Abstract

The present invention is to provide a thermometer that can measure temperature with high precision regardless of fluctuations in heat transfer characteristics resulting from differences in the body types of organisms or from contact with clothing or bedding, a eletronic device with the thermometer and a method for measuring body temperature. A deep-area temperature calculating device (441) calculates the temperature Tcore of a deep area on the basis of a first body-surface temperature and second body-surface temperature from body-surface sensors (31 A and 31 B), and on the basis of a first intermediate temperature and second intermediate temperature from intermediate sensors (32 A and 32 B). Since the temperature Tcore of the deep area is determined from two body-surface temperatures and two intermediate temperatures, the temperature Tcore of the deep area can be calculated regardless of the heat resistance of the thermometer without making any assumptions regarding the heat resistance of the area that extends from the deep area of the human body to the body surface. Thereby, the temperature Tcore of the deep area can be calculated and the body temperature can be measured with high precision regardless of differences in the body type or contact with clothing or bedding.

In the present invention, preferably, described the 1st thermal resistance value has identical value with described the 2nd thermal resistance value; If described the 1st reference temperature is T _B1, described the 1st reference temperature(TR) is T _B2, described the 2nd reference temperature is T _B3, described the 2nd reference temperature(TR) is T _B4The ratio of the thermal resistance value between thermal resistance value between described the 1st reference temperature measuring position and the 1st reference temperature(TR) measuring position and the 2nd reference temperature measuring position and the 2nd reference temperature(TR) measuring position is α, and then described deep temperature calculation step is according to the described deep temperature T of following formula computing _Core:

$\mathrm{Tcore}=\frac{\{\mathrm{<figure-callout\; id="3"\; label="Tb"\; filenames="C200510103113E00681.png,C200510103113E00701.png"\; state="\{\{state\}\}">Tb</figure-callout>}3\&CenterDot;(\mathrm{Tb}1-\mathrm{Tb}2)-\mathrm{\&alpha;}\&CenterDot;\mathrm{<figure-callout\; id="1"\; label="Tb"\; filenames="C200510103113E00711.png,C200510103113E00811.png"\; state="\{\{state\}\}">Tb</figure-callout>}1\&CenterDot;(\mathrm{Tb}3-\mathrm{Tb}4)\}}{\{(\mathrm{Tb}1-\mathrm{Tb}2)-\mathrm{\&alpha;}\&CenterDot;(\mathrm{Tb}3-\mathrm{Tb}4)\}}.$

According to the present invention, because in the deep temperature calculation step, according to the 1st reference temperature T _B1, the 1st reference temperature(TR) T _B2, the 2nd reference temperature T _B3, and the 2nd reference temperature(TR) T _B4The deep temperature of computing live body, thereby when having measured these temperature, the direct substitution arithmetic expression of these measured values, but with regard to the computing deep temperature.Therefore, there is no need to calculate from the deep of live body to the thermal resistance value of surface, make computing simple according to these measured values.And like this, because calculation process is rapid, thereby the response of clinical thermometer is good.

Measurement of bldy temperature method of the present invention is characterised in that to have: the measurement of bldy temperature preparation process, calculate and storage from the deep of described live body to the skin section thermal resistance value of reference temperature measuring position; And the measurement of bldy temperature step, use the described skin section thermal resistance value in this measurement of bldy temperature preparation process, calculate, calculate deep temperature, described measurement of bldy temperature preparation process has: the reference temperature measuring process, measure the calculating reference temperature of described live body; The thermoflux measuring process is measured the calculating thermoflux that described reference temperature measuring position is located; The thermal resistance calculation step, according to described calculating with reference temperature and described calculating calculating deep temperature with the deep of the simultaneously-measured live body of thermoflux, calculating from the deep of described live body to the skin section thermal resistance value of reference temperature measuring position; And storing step, being stored in the described skin section thermal resistance value of calculating in this thermal resistance calculation step, described measurement of bldy temperature step has: the reference temperature measuring process, measure described reference temperature; The thermoflux measuring process is measured described thermoflux; And the deep temperature calculation step, according to described reference temperature, described thermoflux and the described skin section thermal resistance value of in described storing step, storing, calculate described deep temperature.

According to the present invention, owing to use aforementioned clinical thermometer to measure the deep body temperature of live body, thereby can obtain the effect identical with the effect of aforementioned clinical thermometer.That is, owing in the thermal resistance calculation step, use the calculating of the live body that in calculating, is obtained to calculate the skin section thermal resistance value with calculating, thereby can calculate the intrinsic thermal resistance value of live body with reference temperature(TR) with reference temperature with the temperature survey step.Therefore, the deep temperature corresponding can be calculated, deep body temperature can be measured more accurately with the heat transfer characteristic of live body.

And, if in the measurement of bldy temperature preparation process, calculate and storage skin section thermal resistance value, then in the measurement of bldy temperature step, use the skin section thermal resistance value computing deep temperature of being stored, thereby when for the second time later measurement of bldy temperature, can omit the measurement of bldy temperature preparation process.Therefore, the measurement of bldy temperature operation is simplified, and temperature measuring time is shortened.

In the present invention, preferably, described thermoflux measuring process is measured the temperature of reference temperature(TR) measuring position as reference temperature(TR), and wherein said reference temperature(TR) measuring position is different from described reference temperature measuring position, and and described reference temperature measuring position between thermal resistance value be known; Calculate the thermoflux value according to described reference temperature, described reference temperature(TR) and described known thermal resistance value.

According to the present invention, serviceability temperature is measured such short-cut method and is measured thermoflux.

Measurement of bldy temperature method of the present invention is measured the deep body temperature of live body, it is characterized in that having: the temperature survey step, measure respectively from the thermal resistance value of the surface of the described live body temperature of different positions mutually; The Temperature Distribution calculation step is used a plurality of temperature and a plurality of described thermal resistance value measure in described temperature survey step, come the relation of computing thermal resistance value and temperature by curve approximation, as Temperature Distribution; And the deep temperature calculation step, the described Temperature Distribution of use computing in described Temperature Distribution calculation step is come the deep temperature of the described live body of computing.

According to the present invention, measure the temperature of a plurality of measurement section by the temperature survey step.Here, because different mutually to the thermal resistance value of each measurement section from the surface, thus can obtain from the deep of live body to the surface and from the surface by the thermal resistance value of clinical thermometer to the Temperature Distribution of extraneous air the temperature data of different a plurality of measurement points mutually.In the Temperature Distribution calculation step, by carrying out curve approximation according to these a plurality of temperature datas, computing from the deep of live body to the thermal resistance value of surface and the relation of temperature.In the deep temperature calculation step, use the deep temperature of this Temperature Distribution computing live body then.

Owing in the Temperature Distribution calculation step,, thereby consider that the intrinsic thermal resistance value from the deep to the surface of live body comes the deep temperature of computing live body according to the intrinsic thermal resistance value of a plurality of temperature data computing live bodies and the relation of temperature.Because according to the measured value of reality and the thermal resistance value computing deep temperature that sets, thereby there is no need the thermal resistance value from the deep of live body to the surface is assumed to fixed value, like this, even that heat transfer characteristic is existed is different owing to the size difference of live body etc., also can calculate deep temperature exactly according to the surface temperature of live body.

And, because in the Temperature Distribution calculation step, carry out curve approximation by basis in the measured temperature of a plurality of measurement section and come the computing Temperature Distribution, thereby be similar to the situation of the relation of computing thermal resistance value and temperature to compare with for example straight line by 2 measurement points, Temperature Distribution is more accurate.That is, even the relation of thermal resistance value from the live body of human body etc. to the surface and temperature also be non-linear under steady state (SS) usually, thereby when carrying out straight line according to for example 2 measurement data when being similar to, with respect to the Temperature Distribution generation error of reality.In the present invention owing to obtain a plurality of temperature datas and carry out curve approximation, but thereby the Temperature Distribution of the more realistic Temperature Distribution of computing, therefore can be in the deep temperature calculation step deep temperature of computing live body more accurately.

Here, aforementioned deep temperature arithmetic element, Temperature Distribution arithmetic element and thermal resistance calculation unit can be realized by the hardware of IC etc., also can make this computing machine carry out clinical thermometer and realize with control program by computing machine is set in clinical thermometer.

That is, it is characterized in that the clinical thermometer control program is to be used to make the computing machine that is arranged in aforementioned each clinical thermometer to bring into play the functional programs of aforementioned deep temperature arithmetic element, Temperature Distribution arithmetic element and thermal resistance calculation unit.

And aforementioned clinical thermometer can be enclosed in the clinical thermometer by wireless or cable network with control program, records the recording medium of aforementioned clinical thermometer with the embodied on computer readable of control program yet also can pack into.

According to clinical thermometer of the present invention, electronic equipment and measurement of bldy temperature method with clinical thermometer, can obtain following effect, that is: because in live body, the measured value of use from the surface to the temperature of the position with identical thermal resistance value comes the computing deep body temperature, thereby can be irrelevant with the heat transfer characteristic difference that causes by contacting of the build of live body or clothes or bedding etc., measure deep body temperature more accurately.

[first embodiment]

Fig. 1 shows the structured flowchart of the clinical thermometer 1 of present embodiment.This clinical thermometer 1 has: the thermometer body 3 that contacts with surface 2A (with reference to Fig. 3) as the human body 2 (with reference to Fig. 3) of live body, and the display device 4 that was arranged in 3 minutes with thermometer body.

Fig. 2 shows the enlarged drawing that thermometer body 3 is installed in the state on the human body 2, and Fig. 3 illustrates the figure that thermometer body 3 and display device 4 have been installed.

At first, as shown in Figure 2, thermometer body 3 has two (a pair of) temperature measurement unit 3A, 3B as the 1st and the 2nd temperature measurement unit.Temperature measurement unit 3A has: have the thermal insulation material 37 of the surface of contact 300A that contacts with the surface 2A of human body 2, and the thermal insulation material 38A that is arranged on conduct the 1st thermal insulation material between thermal insulation material 37 and the extraneous air as the thermoflux adjustment unit.On the other hand, temperature measurement unit 3B has: have the thermal insulation material 37 of the surface of contact 300B that contacts with the surface 2A of the position of the contact position that is different from temperature measurement unit 3A, and the thermal insulation material 38B that is arranged on conduct the 2nd thermal insulation material between thermal insulation material 37 and the extraneous air as the thermoflux adjustment unit.That is, thermal insulation material 37 is common for temperature measurement unit 3A and temperature measurement unit 3B, has common thermal resistance value.

Temperature measurement unit 3A has: as the surface sensor 31A of the 1st reference temperature measurement section, the temperature of its measuring body surface 2A is as the 1st reference temperature; And as the intermediate sensor 32A of the 1st reference temperature(TR) measurement section, its temperature of measuring the interface 301A between thermal insulation material 37 and the thermal insulation material 38A is as the 1st reference temperature(TR).

And temperature measurement unit 3B has: as the surface sensor 31B of the 2nd reference temperature measurement section, the temperature of its measuring body surface 2A is as the 2nd reference temperature; And as the intermediate sensor 32B of the 2nd reference temperature(TR) measurement section, its temperature of measuring the interface 301B between thermal insulation material 37 and the thermal insulation material 38B is as the 2nd reference temperature(TR).

The thermometer body 3 that is made of these temperature measurement units 3A, 3B constitutes, and can use bonding agent etc. that surface of contact 300A, 300B are attached to respectively on the human body 2, and can use this bonding agent etc. by excellent contact pressure and with surface 2A fluid-tight engagement.In the present embodiment, thermometer body 3 and child's's (human body 2) chest fluid-tight engagement.

Here, expectation is that the sticking position of thermometer body 3 is set at positions such as the forehead of measuring body surface temperature more stably and the back side of head, chest, the back of the body.And even wear clothes on thermometer body 3, thermometer body 3 also can contact with bedding.And, what expect is, thermal insulation material 37,38A, 38B have size to a certain degree, make when temperature measurement unit 3A, 3B are attached on the 2A of surface, can under steady state (SS), be approximately constant by surface 2A and thermal insulation material 37,38A, 38B to the thermoflux on surface from the deep of human body 2.That is to say, what expect is, the size of thermal insulation material 37,38A, 38B is following size, that is: moving in heat is under the situation of equilibrium state, can ignore with the deep that is connected human body 2 and be pasted with the direction direction of quadrature roughly of position of the surface 2A of temperature measurement unit 3A, 3B, particularly, move along the heat of the direction of surface 2A, regard that moving to the heat of surface 2A single shaft direction, thermoflux can be approximately mobile in one direction as from the deep of human body 2.

Temperature measurement unit 3A and temperature measurement unit 3B are configured to have preset distance L mutually.Here, expectation be that preset distance L is set to the distance more than or equal to predetermined value, makes to regard the single shaft direction as moving to the heat of surface 2A from the deep of human body 2, that is, the heat along the direction of surface 2A that can ignore between temperature measurement unit 3A, the 3B moves.

And, can thermal insulation material 37 be set respectively in the part of temperature measurement unit 3A and the part of temperature measurement unit 3B, temperature measurement unit 3A is separated fully with temperature measurement unit 3B.

And the thermal insulation material 38A of temperature measurement unit 3A and the thermal insulation material 38B of temperature measurement unit 3B are made of different materials, and like this, the thermal resistance value of the thermal resistance value of thermal insulation material 38A and thermal insulation material 38B is set to different value.Therefore, the thermoflux value of the thermoflux value of temperature measurement unit 3A and temperature measurement unit 3B is a different value.

Surface sensor 31A, 31B and intermediate sensor 32A, 32B can adopt and the temperature value of the temperature of surface 2A and interface 301A, 301B be converted to the sensor of resistance value or temperature value is converted to sensor of magnitude of voltage etc.In addition, the sensor as temperature value being converted to resistance value can adopt slice heat sensitive resistor, be printed with flexible substrate, platinum temperature detecting resistance of thermistor figure etc.And,, can adopt thermocouple element, PN junction element, diode etc. as the sensor that temperature value is converted to magnitude of voltage.

And temperature measurement unit 3A, 3B are except surface sensor 31A, 31B and intermediate sensor 32A, 32B, and be shown in Figure 1 as described above, also has A/ D converter 34A, 34B and Transmit-Receive Unit 35A, 35B respectively.In addition, because temperature measurement unit 3A, 3B form as one, thereby also can be A/ D converter 34A, 34B as shared A/D converter, Transmit-Receive Unit 35A, 35B are packed into as shared Transmit-Receive Unit.

The resistance value that A/ D converter 34A, 34B are changed surface sensor 31A, 31B and intermediate sensor 32A, 32B or the analog signal conversion of magnitude of voltage become digital signal, and export to Transmit-Receive Unit 35A, 35B.Perhaps, can use RF transducer replacement A/D converter 34A, the 34B that utilizes the CR vibration.

Transmit-Receive Unit 35A, 35B have aerial coil 36A, 36B respectively, and the signal of the temperature value that converts digital signal in A/ D converter 34A, 34B to (resistance value or magnitude of voltage) is sent to display device 4 sides by electric wave.In addition, aerial coil 36A, 36B also can adopt shared aerial coil.

Display device 4 constitutes portable Wristwatch-type as shown in Figure 3, thereby the operator 5 who has the child that thermometer body 3 is housed in arms can be worn.Display device 4 is shown in Figure 1 as described above, have: and thermometer body 3 between the Transmit-Receive Unit 41 of receiving and transmitting signal, display body temperature measurement result's etc. display part 42, operating portion 43 from peripheral operation display device 4, the control module 44 of action of control display device 4, and the storage part 45 of the information that obtained from Transmit-Receive Unit 41 and control module 44 etc. of storage.

Transmit-Receive Unit 41 has aerial coil 46, carries out the electric wave transmitting-receiving between aerial coil 36A, the 36B of thermometer body 3 respectively.And aerial coil 46 makes aerial coil 36A, 36B produce electromotive force by electromagnetic induction by sending electric wave to aerial coil 36A, 36B, and temperature measurement unit 3A, 3B are charged.Therefore, thermometer body 3 is driven by this electromotive force, does not need power supplys such as battery in inside.

Display part 42 uses displays temperature information and operation screens such as liquid crystal panel, can show the deep temperature of for example measured surface temperature, institute's computing etc.In the present embodiment, be provided with display part 42, but display device 4 be worn over visualization display part 42 under the state on the wrist operator 5 in the part of the common dial plate that is equivalent to wrist-watch.

Operating portion 43 constitutes and can use button, control lever, key etc. to be input to the display device 4 from the outside information, and constitute and can select menu according to shown picture on the display part 42 for example, perhaps can import the information of name, the age of other the measured (being the child in the present embodiment), the Measuring Time of body temperature etc.

Control module 44 has deep temperature arithmetic element 441, this deep temperature arithmetic element 441 is according to from the 1st surface temperature of surface sensor 31A, 31B and the 2nd surface temperature and from the 1st medium temperature and the 2nd medium temperature of intermediate sensor 32A, 32B, the deep temperature of computing human body 2.

The 1st surface temperature (the 1st reference temperature) T that deep temperature arithmetic element 441 uses surface sensor 31A to be obtained _B1, the 1st medium temperature (the 1st reference temperature(TR)) T that intermediate sensor 32A obtained _B2, the 2nd surface temperature (the 2nd reference temperature) T that obtained of surface sensor 31B _B3, and the 2nd medium temperature (the 2nd reference temperature(TR)) T that obtained of intermediate sensor 32B _B4Come the deep temperature T of computing human body 2 _Core

Fig. 4 shows from the deep of human body 2 by surface 2A and thermometer body 3 temperature distribution model to extraneous air.For the temperature distribution model of temperature measurement unit 3A and temperature measurement unit 3B, use the expression of solid line (temperature measurement unit 3A side) and dot-and-dash line (temperature measurement unit 3B side).The longitudinal axis is represented temperature (T), and transverse axis is represented thermal resistance (R).Here, if the relation of temperature (T) and thermal resistance (R) is a straight line, then its slope is represented thermoflux Q.Because the temperature distribution model of temperature measurement unit 3A and temperature measurement unit 3B is carried out identical action, thus following be that the center describes with the temperature measurement unit 3A side shown in the solid line.

As shown in Figure 4, from the deep of human body 2 to the temperature transfer model of extraneous air, the deep temperature T of human body 2 _CoreBe constant.In skin section, owing to the influence of the thermal resistance of skin and external air temperature descends body temperature than the more close shell side in deep.In addition, in fact, the part of the housing that is equivalent to thermometer body 3 can be arranged between the surface of contact 300A of surface 2A and temperature measurement unit 3A.And, owing to produce the gap on the microcosmic, thus since the heat radiation etc. in this gap make and also reduce in thermal contact resistance portion temperature.Therefore, under the situation of reality, by the 1st surface temperature T after this thermal contact resistance portion measurement decline with the body temperature of sensor 31A measuring body surface, the surface 2A of temperature measurement unit 3A _B1

And, because self there is thermal resistance (the thermal resistance value R of thermal insulation material 37 in temperature measurement unit 3A _U0), even thereby in temperature measurement unit 3A also occurrence temperature descend, be the 1st medium temperature T on the 301A of the interface of temperature measurement unit 3A _B2In intermediate sensor 32A, measure the 1st medium temperature T _B2And, have thermal resistance value R owing between the interface of temperature measurement unit 3A 301A and extraneous air, exist _U1 Thermal insulation material 38A, thereby temperature descends, and the heat radiation (based on the heat radiation of the thermal resistance value Rv of contact site) of external air temperature contact site is also arranged, thereby temperature further descends and finally becomes external air temperature T _Amb

Under steady state (SS), because the thermoflux Q of each one is constant, thereby slope of a curve is constant in Fig. 4.At this moment, if know the 1st surface temperature T of temperature measurement unit 3A _B1With the 1st medium temperature T _B2, then can use thermal resistance value R _U0, calculate from the surface of the surface sensor 31A side of the 3A of temperature survey unit to the thermoflux Q of interface 301A according to following formula (1) _U1

Here, the thermal resistance value R of thermal contact resistance portion _tExcept as the part suitable with the housing of thermometer body 3 because of the Substance Properties in thermal contact resistance portion changes, also the thermal resistance value because of the thermal insulation material 37 of the clinical thermometer 1 that contacts with surface 2A changes.Promptly, if the pyroconductivity of human body 2 is λ 1, the pyroconductivity of clinical thermometer 1 is λ 2, and the surfaceness of human body 2 is δ 1, and the surfaceness of the surface of contact 300A of clinical thermometer 1 is δ 2, clinical thermometer 1 is P to the pressing force of surface 2A, a soft side's hardness is H in human body 2 and the clinical thermometer 1, and the pyroconductivity of the intervention material between surface 2A and the surface of contact 300A is λ f, and the surfaceness that gets involved material is δ f, and constant is c, for example can obtain according to following formula (3).Like this, because the thermal resistance value R of thermal contact resistance portion _tBecause of various conditions change, thereby in the present embodiment, expectation be the thermal resistance value R of thermal contact resistance portion _tBe set to minimum, and the expectation be to set between surface 2A and surface of contact 300A not vacate the gap.In addition, as the thermal resistance value R that reduces thermal contact resistance portion _tMethod, consider to have and for example smear wet goods and make the good method of contact condition etc. in the contact portion of surface 2A and surface of contact 300A.

Therefore, contain this formula (6) as deep temperature T at deep temperature arithmetic element 441 internal memories _CoreArithmetic expression.

Contain the 1st surface temperature T that is sent from thermometer body 3 at storage part 45 internal memories _B1, the 2nd surface temperature T _B3, the 1st medium temperature T _B2, and the 2nd medium temperature T _B4And, also store the deep temperature T of the human body 2 of 441 computings of deep temperature arithmetic element _Core

Here, storage part 45 constitutes and can store the temperature information relevant with a plurality of human body 2, deep temperature T _CoreDeng storing at each human body 2.And storage part 45 can be stored in and calculate deep temperature T _CoreThe time measured the 1st surface temperature T _B1With the 2nd surface temperature T _B3Deng the measuring position.In addition, in storage part 45, except aforementioned temperature information, can also store the metrical information such as name, age, Measuring Time of the measured (human body 2, child) for example.In the case, these metrical informations can be from operating portion 43 inputs.

In this clinical thermometer 1, be performed as follows action.

Fig. 5 shows the process flow diagram of the action of the clinical thermometer 1 in the present embodiment.

Go up installation thermometer body 3 at human body 2 (being child's chest in the present embodiment), the operator 5 who has child's clinical thermometer 1 in arms is worn on display device 4 on the wrist.When operator 5 connected the switch of display device 4 by the operating portion 43 of operation display device 4, Transmit-Receive Unit 41 sent electric wave to thermometer body 3 (temperature measurement unit 3A and temperature measurement unit 3B).Make aerial coil 36A, 36B produce electromotive force by the electromagnetic induction that utilizes this electric wave, to thermometer body 3 charge (step S1).Thermometer body 3 relies on electromotive force starting (step S2), surface sensor 31A, 31B and intermediate sensor 32A, 32B starting.When these sensors 31A, 31B, 32A, 32B starting, thermometer body 3 sends standby signal (step S3) from Transmit-Receive Unit 35A, 35B to display device 4.

The control module 44 of display device 4 sends temperature survey command signal (step S4) from Transmit-Receive Unit 41 when receiving this standby signal.Thermometer body 3 receives this temperature survey command signal, driving body surface probe 31A, 31B and intermediate sensor 32A, 32B, the 1st surface temperature T of measuring body surface 2A _B1, the 2nd surface temperature T _B3The 1st medium temperature T with interface 301A, 301B _B2, the 2nd medium temperature T _B4(step S5, the 1st temperature survey step and the 2nd temperature survey step).These surface temperature T _B1, T _B3With medium temperature T _B2, T _B4Temperature information become digital signal by A/ D converter 34A, 34B from analog signal conversion, and send to display device 4 by Transmit-Receive Unit 35A, 35B.In addition, expectation is measuring body surface temperature T after the process schedule time _B1, T _B3With medium temperature T _B2, T _B4, so that the heat transfer from the deep of human body 2 to surface 2A becomes steady state (SS) (equilibrium state).

In the deep temperature arithmetic element 441 of control module 44, according to the surface temperature T that is sent from thermometer body 3 _B1, T _B3With medium temperature T _B2, T _B4, use formula (6) computing deep temperature T _Core(step S6, deep temperature calculation step).Control module 44 makes storage part 45 storing temperature T _Core(step S7), and on display part 42 displays temperature T _Core(step S8).Operator 5 can have in arms under child's the state, confirms temperature T on the display part 42 of Wristwatch-type display device 4 _Core

Control module 44 uses built-in timer to from the surface temperature T _B1, T _B3Measurement the time elapsed time of rising count, monitor whether passed through the schedule time (step S9).When elapsed time during more than or equal to the schedule time, get back to step S4, control module 44 sends to thermometer body 3 and measures commencing signals, carries out the surface temperature T once more _B1, T _B3With medium temperature T _B2, T _B4Measurement.

Like this every schedule time measuring body surface temperature T _B1, T _B3With medium temperature T _B2, T _B4Come computing deep temperature T _Core, and be stored in the storage part 45.

According to this first embodiment, can obtain following effect.

(3) since thermometer body 3 constitute and can be attached to integratedly on the skin of human body 2, thereby there is no need picture in the past auxillary temperature and the measurement of sublingual temperature with clinical thermometer 1 maintenance certain hour.Therefore, can improve the usability of thermometer body 3.And, because thermometer body 3 constitutes and can attach integratedly, even thereby situation about using child and baby, children etc. mobile a little down, thermometer body 3 also can well contact with skin, therefore can measure body temperature accurately.And, even under clothes or bedding and thermometer body 3 state of contact, also can calculate deep temperature T _CoreTherefore, even in the situation of wanting continuously long-time monitor temperature to change etc. down, also can measure easily and exactly.

For example in the situation of women's Fundamentals of Measurement body temperature etc. down, must after getting up, under rest state, measure soon etc., many to the restriction of body temperature antihunt means, the measurement of bldy temperature trouble.Yet, if using the clinical thermometer 1 of present embodiment measures, then can be under the state that is attached to for a long time on the 2A of surface continuous coverage body temperature, if thereby under the state that thermometer body 3 has been installed, go to bed, then can be in going to bed Fundamentals of Measurement body temperature automatically, just can finish the measurement of basal body temperature at WA.Therefore, owing to can eliminate the numerous and diverse of measurement of bldy temperature, thereby also can prevent to forget measurement in family and Reiseziel, the energy reliable measurements is basal body temperature accurately.

And the clinical thermometer of present embodiment 1 be owing to can often measure the body temperature of human body 2, thereby is suitable for monitoring the body temperature variation etc. of inpatient for example etc.

(4) since thermometer body 3 and display device 4 constitute separately, and constitute and to communicate by Transmit-Receive Unit 35A, 35B, 41, thereby can with thermometer body 3 that human body 2 contacts on the component count that carries be suppressed to Min., can promote the lightweight and the miniaturization of thermometer body 3.Therefore, even, can not become burden yet, thereby can improve the portability of thermometer body 3 because thermometer body 3 attaches for a long time.And,, can further promote the lightweight and the miniaturization of thermometer body 3 by the control module 44 with deep temperature arithmetic element 441 is arranged on display device 4 sides.

Because Transmit-Receive Unit 35A, 35B, 41 constitute by aerial coil 36A, 36B, 46 and carry out radio communication, thereby distribution etc. can not become obstacle, can improve the usability of clinical thermometer 1.

And because display device 4 forms Wristwatch-type, thereby operator 5 can be worn over visualization display part 42 on the wrist.Therefore, as present embodiment, show owing to can under the state of having the child who wants take temperature in arms, confirm body temperature, thereby can improve the operability of clinical thermometer 1.

[second embodiment]

Below, with reference to the accompanying drawings second embodiment of the present invention is described.

Fig. 6 shows the structured flowchart of the clinical thermometer 1 of present embodiment.This clinical thermometer 1 has: the thermometer body 3 that contacts with surface 2A (with reference to Fig. 8) as the human body 2 (with reference to Fig. 8) of live body, and the display device 4 that are provided with separately with thermometer body 3.

Fig. 7 shows the enlarged drawing that thermometer body 3 is installed in the state on the human body 2, and Fig. 8 illustrates the figure that thermometer body 3 and display device 4 have been installed.

At first, as shown in Figure 7, thermometer body 3 has two (a pair of) temperature measurement unit 3A, 3B as the 1st and the 2nd temperature measurement unit.Temperature measurement unit 3A has: as the surface sensor 31A of the 1st reference temperature measurement section, it has the surface of contact 300A that contacts with the surface 2A of human body 2, and the temperature of measuring this surface 2A is as the 1st reference temperature; As the outer surface sensor 33A of the 1st reference temperature(TR) measurement section, it has the outside surface 302A of the extraneous air side that is exposed to temperature measurement unit 3A, and the temperature of measuring this outside surface 302A is as the 1st reference temperature(TR); And as the thermal insulation material 37A of the 1st thermal insulation material, it is between surface sensor 31A and outer surface sensor 33A.

And, temperature measurement unit 3B and temperature measurement unit 3A are provided with separately, and have: as the surface sensor 31B of the 2nd reference temperature measurement section, it has the surface of contact 300B that contacts with the surface 2A of the position of the contact position that is different from temperature measurement unit 3A, and the temperature of measuring this surface 2A is as the 2nd reference temperature; As the outer surface sensor 33B of the 2nd reference temperature(TR) measurement section, it has the outside surface 302B of the extraneous air side that is exposed to temperature measurement unit 3B, and the temperature of measuring this outside surface 302B is as the 2nd reference temperature(TR); And as the thermal insulation material 37B of the 2nd thermal insulation material, it is between surface sensor 31B and outer surface sensor 33B.

The thermal insulation material 37A of temperature measurement unit 3A uses pyroconductivity λ identical materials to constitute with identical sectional area with the thermal insulation material 37B of temperature measurement unit 3B.Here, by being the thickness setting of each thermal insulation material d and d ', the thermal resistance value of the thermal resistance value of thermal insulation material 37A and thermal insulation material 37B is set to different value.Therefore, the ratio α of thermal resistance value is by d/d ' expression.That is, by changing thickness, thermal insulation material 37A and thermal insulation material 37B play the effect of thermoflux adjustment unit.

Here, can adopt different materials formation thermal insulation material 37A and thermal insulation material 37B to form the thermoflux adjustment unit, yet in the case, be necessary to measure in advance the thermal resistance value of each thermal insulation material.If be the thermal insulation material of same material as present embodiment, then can know the thickness ratio.

And if thermal insulation material is a same material, then pyroconductivity λ is identical, thereby the thermal contact resistance difference of the surface of temperature measurement unit 3A and temperature measurement unit 3B is also little.

The same chest fluid-tight engagement with child's (human body 2) of the thermometer body 3 that constitutes by these temperature measurement units 3A, 3B with first embodiment.

Here, expectation is that the sticking position of thermometer body 3 is set at skin temperature on the human body 2 and is not easy to be subjected to extraneous air influence, positions such as the forehead of measuring body surface temperature and the back side of head, chest, the back of the body more stably.And, what expect is, thermal insulation material 37A, 37B have size to a certain degree, make when temperature measurement unit 3A, 3B are attached on the 2A of surface, can under steady state (SS), be approximately constant to the thermoflux of outside surface 302A, 302B from the deep of human body 2 by surface 2A and thermal insulation material 37A, 37B.Promptly, what expect is, the size of thermal insulation material 37A, 37B is following size, that is: moving in heat is under the situation of equilibrium state, can ignore with the deep that is connected human body 2 and be pasted with the direction direction of quadrature roughly of position of the surface 2A of temperature measurement unit 3A, 3B, be specially along the heat of the direction of surface 2A and move, regard that moving to the heat of surface 2A single shaft direction, thermoflux can be approximately mobile in one direction as from the deep of human body 2.

Temperature measurement unit 3A is the same with first embodiment with temperature measurement unit 3B to be configured to have mutually preset distance L.

Surface sensor 31A, 31B and outer surface sensor 33A, 33B can adopt and the temperature value of the temperature of surface 2A or outside surface 302A, 302B be converted to the sensor of resistance value or temperature value is converted to sensor of magnitude of voltage etc.In addition, the sensor as temperature value being converted to resistance value can adopt cited in the first embodiment sensor.

And temperature measurement unit 3A, 3B are except surface sensor 31A, 31B and outer surface sensor 33A, 33B, and be shown in Figure 1 as described above, also has A/ D converter 34A, 34B and Transmit-Receive Unit 35A, 35B respectively.

The resistance value that A/ D converter 34A, 34B are changed surface sensor 31A, 31B and outer surface sensor 33A, 33B and the analog signal conversion of magnitude of voltage become digital signal, and export to Transmit-Receive Unit 35A, 35B.Perhaps, can use RF transducer replacement A/D converter 34A, the 34B that utilizes the CR vibration.

Display device 4 constitutes portable Wristwatch-type as shown in Figure 8, thereby the operator 5 who has the child that thermometer body 3 is housed in arms can be worn.Display device 4 is shown in Figure 6 as described above, have: and thermometer body 3 between the Transmit-Receive Unit 41 of receiving and transmitting signal, display body temperature measurement result's etc. display part 42, operating portion 43 from peripheral operation display device 4, the control module 44 of action of control display device 4, and the storage part 45 of the information that obtained from Transmit-Receive Unit 41 and control module 44 etc. of storage.

Transmit-Receive Unit 35A, 35B, Transmit-Receive Unit 41, display part 42 and operating portion 43 omit explanation owing to identical with first embodiment.

Control module 44 has deep temperature arithmetic element 441, this deep temperature arithmetic element 441 is according to from the 1st surface temperature (the 1st reference temperature) of surface sensor 31A, 31B and the 2nd surface temperature (the 2nd reference temperature) and from the 1st hull-skin temperature (the 1st reference temperature(TR)) and the 2nd hull-skin temperature (the 2nd reference temperature(TR)) of outer surface sensor 33A, 33B, the deep temperature of computing human body 2.

The 1st surface temperature T that deep temperature arithmetic element 441 uses surface sensor 31A to be obtained _B1, the 1st reference temperature(TR) T that obtained of outer surface sensor 33A _B2, the 2nd surface temperature T that obtained of surface sensor 31B _B3, the 2nd reference temperature(TR) T that obtained of outer surface sensor 33B _B4, and the 1st thermal resistance value R of temperature measurement unit 3A _U1The 2nd thermal resistance value R with temperature measurement unit 3B _U2Ratio α come the deep temperature T of computing human body 2 _Core

Fig. 9 shows from the deep of human body 2 by surface 2A and thermometer body 3 temperature distribution model to extraneous air.Because the temperature distribution model of temperature measurement unit 3A and temperature measurement unit 3B is identical, thereby the temperature distribution model to temperature measurement unit 3A illustrates in Fig. 9.

As shown in Figure 9, from the deep of human body 2 to the temperature transfer model of extraneous air, the deep temperature T of human body 2 _CoreBe constant.In skin section, owing to the influence of the thermal resistance of skin and external air temperature descends body temperature than the more close shell side in deep.In addition, in fact, owing to producing the gap on the microcosmic between surface 2A and the temperature measurement unit 3A, thereby owing to the heat radiation in this gap, make and also reduce in thermal contact resistance portion temperature.Therefore, under the situation of reality, by the 1st surface temperature T after this thermal contact resistance portion measurement decline with the body temperature of temperature measurement unit 3A measuring body surface 2A _B1

Because also there is thermal resistance (the 1st thermal resistance value R in temperature measurement unit 3A self _U1), thereby also occurrence temperature decline in temperature measurement unit 3A, on the outside surface 302A of temperature measurement unit 3A the 1st hull-skin temperature T _B2In outer surface sensor 33A, measure the 1st hull-skin temperature T _B2And owing to also there is the heat radiation of external air temperature contact site between the outside surface 302A of temperature measurement unit 3A and extraneous air, thereby temperature descends, and finally becomes external air temperature T _Amb

Here, when transverse axis is made as thermal resistance, when the longitudinal axis was made as temperature, the slope of temperature distribution history was thermoflux Q, and under steady state (SS), because the thermoflux Q of each one is constant, thereby slope of a curve is constant in Fig. 9.At this moment, as long as know the 1st surface temperature T of temperature measurement unit 3A _B1With the 1st hull-skin temperature T _B2, with regard to the 1st thermal resistance value R of energy serviceability temperature measuring unit 3A _U1, calculate from the surface of the surface sensor 31A side of temperature measurement unit 3A to the thermoflux Q of outside surface 302A according to following formula (7) _U1

[mathematical expression 9]

$\mathrm{<figure-callout\; id="1"\; label="Qu"\; filenames="C200510103113E00711.png,C200510103113E00811.png"\; state="\{\{state\}\}">Qu</figure-callout>}1=\frac{\mathrm{Tb}1-\mathrm{<figure-callout\; id="2"\; label="Tb"\; filenames="C200510103113E00701.png,C200510103113E00721.png"\; state="\{\{state\}\}">Tb</figure-callout>}2}{\mathrm{<figure-callout\; id="1"\; label="Ru"\; filenames="C200510103113E00711.png,C200510103113E00811.png"\; state="\{\{state\}\}">Ru</figure-callout>}1}\&CenterDot;\&CenterDot;\&CenterDot;\left(7\right)$

On the other hand, the part of fitting in skin section and thermal contact resistance portion, promptly from the deep of human body 2 to the thermoflux Q of the part of surface 2A (in fact from the deep to the part of surface of contact 300A) _S+tUse the deep body temperature T of human body 2 _CoreAnd from the deep of human body 2 to the thermal resistance R of the part of surface 2A _s+ R _tRepresent by following formula (8).

[mathematical expression 10]

$\mathrm{Qs}+t=\frac{\mathrm{Tcore}-\mathrm{<figure-callout\; id="1"\; label="Tb"\; filenames="C200510103113E00711.png,C200510103113E00811.png"\; state="\{\{state\}\}">Tb</figure-callout>}1}{\mathrm{Rs}+\mathrm{Rt}}\&CenterDot;\&CenterDot;\&CenterDot;\left(8\right)$

Here, the thermal resistance value R of thermal contact resistance portion _tBecause of the Substance Properties in thermal contact resistance portion changes, also the thermal resistance value because of the clinical thermometer 1 ( thermal insulation material 37A, 37B) that contacts with surface 2A changes except the same with first embodiment.

Because thermoflux Q is constant in each one, thereby at the thermoflux Q of thermometer body 3 inside _U1With from the deep of human body 2 to the thermoflux Q of the part of surface 2A _S+tEquate (Q _U1=Q _{s + t}).Therefore, formula (7) and formula (8) are organized into following formula (9), deep temperature T _CoreObtain according to this formula (9).

[mathematical expression 11]

$\mathrm{Tcore}=\frac{\mathrm{Rs}+\mathrm{<figure-callout\; id="1"\; label="Rt\; Ru"\; filenames="C200510103113E00711.png,C200510103113E00811.png"\; state="\{\{state\}\}">Rt</figure-callout>}}{\mathrm{Ru}}\&CenterDot;(\mathrm{Tb}1-\mathrm{Tb}2)+\mathrm{<figure-callout\; id="1"\; label="Tb"\; filenames="C200510103113E00711.png,C200510103113E00811.png"\; state="\{\{state\}\}">Tb</figure-callout>}1\&CenterDot;\&CenterDot;\&CenterDot;\left(9\right)$

Here, from the deep of human body 2 to the thermal resistance value R of the part of surface 2A _s+ R _tIt is unknown-value.Therefore, in temperature measurement unit 3B, if equally with temperature measurement unit 3A obtain the 2nd surface temperature T from surface sensor 31B and outer surface sensor 33B _B3With the 2nd hull-skin temperature T _B4, deep temperature T then _CoreCan obtain by following formula (10).

[mathematical expression 12]

$\mathrm{Tcore}=\frac{\mathrm{Rs}+\mathrm{<figure-callout\; id="2"\; label="Rt\; Ru"\; filenames="C200510103113E00701.png,C200510103113E00721.png"\; state="\{\{state\}\}">Rt</figure-callout>}}{\mathrm{Ru}}\&CenterDot;(\mathrm{Tb}3-\mathrm{Tb}4)+\mathrm{<figure-callout\; id="3"\; label="Tb"\; filenames="C200510103113E00681.png,C200510103113E00701.png"\; state="\{\{state\}\}">Tb</figure-callout>}3\&CenterDot;\&CenterDot;\&CenterDot;\left(10\right)$

Here, owing to know the 1st thermal resistance value R of temperature measurement unit 3A _U1The 2nd thermal resistance value R with temperature measurement unit 3B _U2Ratio α, thereby when from formula (9) and formula (10) cancellation thermal resistance value R _s+ R _tThe time, usage rate α obtains deep temperature T according to following formula (11) _Core

[mathematical expression 13]

$\mathrm{Tcore}=\frac{\mathrm{<figure-callout\; id="3"\; label="Tb"\; filenames="C200510103113E00681.png,C200510103113E00701.png"\; state="\{\{state\}\}">Tb</figure-callout>}3\&CenterDot;(\mathrm{Tb}1-\mathrm{Tb}2)-\mathrm{\&alpha;}\&CenterDot;\mathrm{<figure-callout\; id="1"\; label="Tb"\; filenames="C200510103113E00711.png,C200510103113E00811.png"\; state="\{\{state\}\}">Tb</figure-callout>}1\&CenterDot;(\mathrm{Tb}3-\mathrm{Tb}4)}{(\mathrm{Tb}1-\mathrm{Tb}2)-\mathrm{\&alpha;}\&CenterDot;(\mathrm{Tb}3-\mathrm{Tb}4)}\&CenterDot;\&CenterDot;\&CenterDot;\left(11\right)$

Therefore, contain this formula (11) as deep temperature T at deep temperature arithmetic element 441 internal memories _CoreArithmetic expression.

In storage part 45, stored because identical with first embodiment, thereby omit explanation.

[the 5th embodiment]

Below, the 5th embodiment of the present invention is described.The 1st measurement section in the 5th embodiment and the 4th embodiment and the thermal resistance value of the 2nd measurement section are that common this point is different, in addition, identical with the 4th embodiment.

Figure 15 shows the thermometer body 3 of the 5th embodiment.In this Figure 15, thermometer body 3 is the same with the 4th embodiment to have temperature measurement unit 3A, 3B.

Temperature measurement unit 3A has: have the thermal insulation material 37 of the surface of contact 300A that contacts with the surface 2A of human body 2, and the thermal insulation material 38A that is arranged on conduct the 1st thermal insulation material between thermal insulation material 37 and the extraneous air.On the other hand, temperature measurement unit 3B has: have the thermal insulation material 37 of the surface of contact 300B that contacts with the surface 2A of the position of the contact position that is different from temperature measurement unit 3A, and the thermal insulation material 38B that is arranged on conduct the 2nd thermal insulation material between thermal insulation material 37 and the extraneous air.That is, thermal insulation material 37 is common for temperature measurement unit 3A and temperature measurement unit 3B, therefore, has common thermal resistance value R _U0

Temperature measurement unit 3A has: surface sensor 31A, and it contacts with surface 2A, the temperature of measuring body surface 2A; Interface sensor 39A, it measures the temperature of the interface 301A between thermal insulation material 37 and the thermal insulation material 38A; And intermediate sensor 32A, it is arranged between surface sensor 31A and the interface sensor 39A.And temperature measurement unit 3B is the same with temperature measurement unit 3A to have: surface sensor 31B; Interface sensor 39B, it measures the temperature of the interface 301B between thermal insulation material 37 and the thermal insulation material 38B; And intermediate sensor 32B.

In addition, the thermal resistance value from surface 2A to intermediate sensor 32A, 32B is a given value, is set to thermal resistance value R respectively _UA1With thermal resistance value R _UB1And, in the present embodiment, adopt to make intermediate sensor 32A, 32B the method for being provided with, with these thermal resistance value R apart from phase or the like apart from surface 2A _UA1, R _UB1Be set at identical value (R _UA1=R _UB1).

On the other hand, the thermal resistance value of thermal insulation material 38A and thermal insulation material 38B is set to different value mutually, therefore, temperature measurement unit 3A, 3B are different thermal resistance value as a whole, yet the thermal resistance value till surface sensor 31A, the 31B, thermal resistance value and the thermal resistance value till interface sensor 39A, 39B till intermediate sensor 32A, 32B are set to equal respectively.

In the 5th embodiment, the same with the 4th embodiment, two Temperature Distribution T of computing in Temperature Distribution arithmetic element 442 _A(R) and Temperature Distribution T _B(R), deep temperature arithmetic element 441 is according to these Temperature Distribution T _A(R) and Temperature Distribution T _B(R) computing deep temperature T _CoreAt this moment, because the thermal resistance value difference as a whole of temperature measurement unit 3A, 3B, thereby at the thermoflux difference of internal flow, Temperature Distribution T _A(R) and Temperature Distribution T _B(R) also different respectively.Yet, because the thermal resistance value (R=0) till surface sensor 31A, the 31B, the thermal resistance value (R=R till intermediate sensor 32A, the 32B _UA1=R _UB1) and the thermal resistance value (R=R till interface sensor 39A, the 39B _U2) be set to respectively equal, thereby when deep temperature arithmetic element 441 computing deep temperatures and since in computing cancellation these common thermal resistance value, thereby can not use these thermal resistance value and computing deep temperature T _CoreThat is only measured surface temperature T, according to surface sensor 31A, 31B _B1, T _B3, the measured medium temperature T of intermediate sensor 32A, 32B _B2, T _B4, and the measured interface temperature T of interface sensor 39A, 39B _B5, T _B6Measured value, can measure deep temperature T _Core

According to the 5th embodiment, except can obtaining the effect identical, also can obtain following effect with the effect of (11) of the 4th embodiment.

(12) be configured in the common thermal insulation material 37 owing to temperature measurement unit 3A, 3B, thereby can make temperature measurement unit 3A, 3B constitute one, therefore can improve the usability of clinical thermometer 1.

Because temperature measurement unit 3A, 3B have different thermal resistance value mutually as a whole, and, in the thermal resistance value of the position of surface sensor 31A, 31B, equate respectively in the thermal resistance value of the position of intermediate sensor 32A, 32B and thermal resistance value in the position of interface sensor 39A, 39B, thereby in the deep temperature computing of deep temperature arithmetic element 441, cancellation these thermal resistance value.Therefore, the calculation process in the deep temperature arithmetic element 441 becomes simply, can carry out calculation process rapidly.

And, owing to when the computing deep temperature, do not need each thermal resistance value, if thereby temperature measurement unit 3A, 3B have different thermal resistance value mutually as a whole, and in the thermal resistance value of the position of surface sensor 31A, 31B, equate respectively, then there is no need this setting value of strict control in the thermal resistance value of the position of intermediate sensor 32A, 32B and thermal resistance value in the position of interface sensor 39A, 39B.Therefore, carry out the management of thermal resistance value owing to there is no need when the manufacturing of clinical thermometer 1 strictness, thereby can simplify the manufacturing management of clinical thermometer 1.

And, if for example wear clothes and clothes contacted with clinical thermometer 1 from clinical thermometer 1, contact with bedding when perhaps lying on the bedding when clinical thermometer 1 is installed, then the thermal resistance value of temperature measurement unit 3A, 3B changes, yet, just can accurately measure deep temperature as long as the thermal resistance value of the integral body of temperature measurement unit 3A, 3B is different mutually.Therefore, the restriction of the posture of installing during the clinical thermometer 1 and clothes etc. can be reduced, the usability of clinical thermometer 1 can be improved.

[the 6th embodiment]

Below, with reference to the accompanying drawings the 6th embodiment of the present invention is described.

Figure 16 shows the structured flowchart of the clinical thermometer 1 of present embodiment.This clinical thermometer 1 has: the thermometer body 3 that contacts with surface as the human body 2 (with reference to Figure 17) of live body, and the display device 4 that are provided with separately with thermometer body 3.

Figure 17 shows thermometer body 3 and is installed in figure on the human body 2, and Figure 18 illustrates the figure that thermometer body 3 and display device 4 have been installed.

At first, as shown in figure 17, thermometer body 3 has: as the surface sensor 31 of reference temperature measurement section, it contacts with the surface 2A of human body 2, detects the temperature of this surface 2A; As the outer surface sensor 33 of reference temperature(TR) measurement section, it has the outside surface 30 of the extraneous air side of thermometer body of being exposed to 3, and detects the temperature of this outside surface 30; And thermal insulation material 37, it is between surface sensor 31 and outer surface sensor 33.This thermometer body 3 constitutes can use bonding agent etc. that the face of surface sensor 31 sides is attached on the human body 2, and uses this bonding agent etc. to make thermometer body 3 and surface 2A by excellent contact pressure and fluid-tight engagement.In the present embodiment, thermometer body 3 and child's's (human body 2) forehead fluid-tight engagement.

Here, expectation is that the sticking position of thermometer body 3 is set at skin temperature on the human body and is not easy to be subjected to extraneous air influence, positions such as the forehead of measuring body surface temperature and the back side of head, chest, the back of the body more stably.And, what expect is, thermal insulation material 37 has size to a certain degree, make when thermometer body 3 is attached on the 2A of surface, can under steady state (SS), be approximately constant from the deep of human body 2 by surface 2A and thermal insulation material 37 to the thermoflux of outside surface 30, can be thought of as and thermal insulation material 37 is formed have more than or equal to the essentially rectangular shape of the size of 10cm in length and breadth.In the case, owing to can ignore with the deep that is connected human body 2 and be pasted with the direction direction of quadrature roughly of position of the surface 2A of thermometer body 3, specifically the heat along the direction of surface 2A moves, regard move to the heat of surface 2A as the single shaft direction as from the deep of human body 2, heat is moved obtain rectilinearity, thereby thermoflux can be approximately constant.

Surface sensor 31 and outer surface sensor 33 can adopt cited in the first embodiment sensor.

And thermometer body 3 is except surface sensor 31 and outer surface sensor 33, and is shown in Figure 1 as described above, also has A/D converter 34 and Transmit-Receive Unit 35.

A/D converter 34 becomes digital signal to the resistance value of being changed and the analog signal conversion of magnitude of voltage in surface sensor 31 and outer surface sensor 33, and exports to Transmit-Receive Unit 35.

Transmit-Receive Unit 35 has aerial coil 36, and the signal wave of the temperature value that converts digital signal in A/D converter 34 to (resistance value or magnitude of voltage) is sent to display device 4 sides.

Display device 4 constitutes portable Wristwatch-type as shown in figure 18, thereby the operator 5 who has the child that thermometer body 3 is housed in arms can be worn.Display device 4 is shown in Figure 16 as described above, have: and thermometer body 3 between the Transmit-Receive Unit 41 of receiving and transmitting signal, display body temperature measurement result's etc. display part 42, operating portion 43 from peripheral operation display device 4, the control module 44 of action of control display device 4, and the storage part (storage unit) 45 of the information that obtained from Transmit-Receive Unit 41 and control module 44 etc. of storage.

Transmit-Receive Unit 41 has aerial coil 46, and the aerial coil 36 of thermometer body 3 between carry out the electric wave transmitting-receiving.And aerial coil 46 makes aerial coil 36 utilize electromagnetic induction to produce electromotive force by sending electric wave to aerial coil 36, and thermometer body 3 is charged.Therefore, thermometer body 3 is driven by this electromotive force, does not need power supplys such as battery in inside.

Display part 42 and operating portion 43 is because identical with first embodiment, so omit explanation.

Control module 44 has: thermoflux computing unit 444, and it calculates from surface 2A to outside surface the thermoflux 30 according to from the surface temperature of surface sensor 31 with from the hull-skin temperature of outer surface sensor 33; Thermal resistance calculation unit 443, it is according to the thermoflux of being calculated, and calculates from the deep of human body 2 to the thermal resistance value of surface 2A; And deep temperature arithmetic element 441, the thermal resistance value that it is calculated according to this thermal resistance calculation unit 443, the deep temperature of computing human body 2.

The surface temperature T that thermoflux computing unit 444 is measured according to surface sensor 31 _B1, and the measured hull-skin temperature T of outer surface sensor 33 _B2, calculate the thermoflux Q that between surface 2A and outside surface 30, flows _u

Figure 19 shows from the deep of human body 2 by surface 2A and thermometer body 3 temperature distribution model to extraneous air.As shown in Figure 19, from the deep of human body 2 to the temperature transfer model of extraneous air, the deep temperature T of human body 2 _CoreBe constant.In skin section, owing to the influence of the thermal resistance of skin and external air temperature descends body temperature than the more close shell side in deep.And, owing to producing the gap on the microcosmic between surface 2A and the thermometer body 3, thereby owing to the heat radiation in this gap, make and also reduce in thermal contact resistance portion temperature.In addition, under the situation of reality, by the temperature T after this thermal contact resistance portion measurement decline with the body temperature of thermometer body 3 measuring body surface 2A _B1

Because self also there is thermal resistance in thermometer body 3, thus in thermometer body 3 also occurrence temperature descend, be temperature T at the outside surface 30 of thermometer body 3 _B2In outer surface sensor 33, measure this temperature T _B2And owing to also have the heat radiation of external air temperature contact site between the outside surface 30 of thermometer body 3 and extraneous air, thereby temperature descends, and finally becomes external air temperature T _Amb

Here, when transverse axis is made as thermal resistance, when the longitudinal axis was made as temperature, the slope of temperature distribution history was thermoflux Q, and under steady state (SS), because the thermoflux Q of each one is constant, thereby slope of a curve is constant in Figure 19.At this moment, because the thermal resistance value R of thermometer body 3 _U0With the thermal resistance value of thermal insulation material about equally and be known, if thereby know the surface temperature T of thermometer body 3 _B1With hull-skin temperature T _B2, then can use following formula to calculate thermoflux Q _u

[mathematical expression 15]

$Q_u=\frac{T_{b1}-T_{b2}}{R_{u0}}$

Thermal resistance calculation unit 443 uses the thermoflux Q that is obtained by this mathematical expression 15 _u, by following calculating from the deep of human body 2 the thermal resistance value R to the part of surface 2A _s+ R _t

The part of fitting in skin section and thermal contact resistance portion, promptly from the deep of human body 2 to the thermoflux Q of the part of surface 2A _S+tUse the deep body temperature T of human body 2 _CoreWith thermal resistance R _s+ R _tBe expressed from the next.

[mathematical expression 16]

$Q_{s+t}=\frac{T_{\mathrm{core}}-T_{b1}}{R_s+R_t}$

Here, because thermoflux Q is constant in each one, thereby the thermoflux Q of thermometer body 3 inside _uWith from the deep of human body 2 to the thermoflux Q of the part of surface 2A _S+tEquate.Therefore, these formulas can be organized into following formula.

Shown in this formula, if know the calculating surface temperature T that sensor 31 measured thermal resistance calculation in surface are used _{0, b1}, the calculating hull-skin temperature T that uses of outer surface sensor 33 measured thermal resistance calculation _{0, b2}, and the calculating deep temperature T in the deep used of thermal resistance calculation _{0, core}, then can obtain from the deep skin section thermal resistance value R of the part of surface 2A _s+ R _t

[mathematical expression 17]

$R_s+R_t=\frac{T_{0,\mathrm{core}}-T_{0,b1}}{T_{0,b1}-T_{0,\mathrm{<figure-callout\; id="2"\; label="b"\; filenames="C200510103113E00701.png,C200510103113E00721.png"\; state="\{\{state\}\}">b</figure-callout>}2}}\&CenterDot;R_{u0}(R_s+R_t=\frac{T_{0,\mathrm{core}}-T_{0,b1}}{Q_u})$

The control module 44 of display device 4 sends temperature survey command signal (step S14) from Transmit-Receive Unit 41 when receiving this standby signal.Thermometer body 3 receives this temperature survey command signal, driving body surface probe 31 and outer surface sensor 33, the calculating surface temperature T of measuring body surface 2A _{0, b1}With the calculating of outside surface 30 external air temperature T _{0, b2}(step S15 and step S16, thermal resistance calculation temperature survey step).These calculate uses the surface temperature T _{0, b1}Use external air temperature T with calculating _{0, b2}Temperature information in A/D converter 34, become digital signal from analog signal conversion, send to display device 4 (step S17) by Transmit-Receive Unit 35.In addition, expectation is to use the surface temperature T through measuring after the schedule time to calculate _{0, b1}Use external air temperature T with calculating _{0, b2}, so that the heat transfer from the deep of human body 2 to surface 2A becomes steady state (SS).

Here, control module 44 must be judged and is to use the temperature information that is obtained from surface sensor 31 and outer surface sensor 33 to carry out skin section thermal resistance value R _s+ R _tCalculating, still carry out the calculating of deep temperature.Therefore, in control module 44, be provided with and do not make illustrated selected cell.This selected cell can constitute, and for example show to select either party the selection picture in " measurement of bldy temperature ready mode " and " measurement of bldy temperature pattern " on display part 42, makes operator 5 select arbitrary pattern by operating operation portion 43 grades.Here, operator 5 can selective body temperature measurement ready mode, indication control module 44 serviceability temperature information calculations skin section thermal resistance value R _s+ R _tThe control module 44 of display device 4 is according to the calculating surface temperature T that is sent from thermometer body 3 _{0, b1}Use hull-skin temperature T with calculating _{0, b2}, in thermoflux computing unit 444, calculate thermoflux Q _S+r(step S18, thermoflux calculation procedure).

Then, display device 4 display requirement in display part 42 is used to import the calculating deep temperature T of the deep temperature of using as thermal resistance calculation _{0, core}Picture.Operator 5 imports measured calculating deep temperature T by operating operation portion 43 _{0, core}Like this, display device 4 obtains to calculate and uses deep temperature T _{0, core}(step S19).In addition, calculating deep temperature T _{0, core}Can use the known clinical thermometer of measuring auxillary temperature or sublingual temperature etc. to measure.

The thermal resistance calculation unit 443 of control module 44 is according to obtained calculating deep temperature T _{0, core}The thermoflux Q that is calculated with thermoflux computing unit 444 _S+r, use mathematical expression 3 to calculate from the deep of human body 2 to the skin section thermal resistance value R of surface 2A _s+ R _t(step S20, thermal resistance calculation step).The skin section thermal resistance value R that control module 44 is calculated storage part 45 storages _s+ R _t(step S21, storing step) finishes measurement of bldy temperature and prepares.

Below, the action of the clinical thermometer 1 in the measurement of bldy temperature step during to the body temperature of continuous coverage human body 2 practically describes.

Figure 21 is the process flow diagram that the action of clinical thermometer 1 is shown.In this Figure 21, at first the same when using clinical thermometer 1 to measure the body temperature of human body 2 with abovementioned steps S11, be used to make aerial coil 36 electromagnetic induction, to thermometer body 3 charge (step S31) from the electric wave of the aerial coil 46 of display device 4.When each sensor 31,33 of thermometer body 3 starts (step S32), thermometer body 3 sends standby signals (step S33) to display device 4.Like this, display device 4 is judged as the preparation that thermometer body 3 has been carried out take temperature, reads the skin section thermal resistance value R of human body 2 from storage part 45 _s+ R _t(step S34).Then, send measurement of bldy temperature commencing signal (step S35) by Transmit-Receive Unit 41 to thermometer body 3.

Thermometer body 3 receptions are brought into use the surface temperature T of surface sensor 31 measuring body surface 2A from the measurement commencing signal of display device 4 _B1Measure hull-skin temperature T with use outer surface sensor 33 _B2(step S36, temperature survey step).The temperature value T that surface sensor 31 is detected _B1, T _B2After being converted to digital signal by A/D converter 34, send to display device 4 by Transmit-Receive Unit 35.

In addition, in control module 44,, thereby be necessary to use aforesaid selected cell to select " measurement of bldy temperature pattern " owing to the temperature information computing deep temperature that uses from surface sensor 31 and outer surface sensor 33.

In the deep temperature arithmetic element 441 of control module 44, according to the surface temperature T that is sent from thermometer body 3 _B1With hull-skin temperature T _B2, the aforementioned formula computing deep temperature T shown in the use in the present embodiment _Core(step S37, deep temperature calculation step).Control module 44 makes storage part 45 storing temperature T _Core(step S38), and on display part 42 displays temperature T _Core(step S39).Operator 5 can have in arms under child's the state, confirms temperature T on the display part 42 of Wristwatch-type display device 4 _Core

Control module 44 uses built-in timer to from the surface temperature T _B1Measurement the time elapsed time of rising count, monitor whether passed through the schedule time (step S40).When elapsed time during more than or equal to the schedule time, get back to step S35, control module 44 sends to thermometer body 3 and measures commencing signals, carries out the surface temperature T once more _B1With hull-skin temperature T _B2Measurement.

Like this every schedule time measuring body surface temperature T _B1With hull-skin temperature T _B2Come computing deep temperature T _Core, and be stored in the storage part 45.

In addition, because skin section thermal resistance value R _s+ R _tExcept the special circumstances that build that human body 2 is arranged sharply changes etc., significantly do not change, thereby can when the beginning take temperature, at first once use thermoflux computing unit 444 calculating thermoflux Q _S+r, and use thermal resistance calculation unit 443 to calculate skin section thermal resistance value R _s+ R _tIn addition, sharply change etc. and make under the situation that the heat transfer characteristic of human body 2 changes, can obtain the temperature data T in deep once more at build _{0, core}, measuring body surface temperature T _B1With hull-skin temperature T _B2, calculate thermoflux Q _S+rWith skin section thermal resistance value R _s+ R _t

And, because the intrinsic skin section thermal resistance value R of human body 2 _s+ R _tVariation little, thereby under the situation that reuses clinical thermometer 1, also can use the skin section thermal resistance value R of last computation _s+ R _t, therefore, from for the second time measurement the time, can shorten to the time till measurement of bldy temperature begins.In the case, as long as the skin section thermal resistance value R of a plurality of human bodies 2 _s+ R _tBe stored in the storage part 45, just can operate, read and utilize once more the skin section thermal resistance value R of last computation by using operating portion 43 _s+ R _tIn the case, when carrying out the measurement of bldy temperature step, the live body that can use operating portion 43 to be used to specify human body 2 is selected.

(13) since thermal resistance calculation unit 443 according to the calculating of human body 2 surface temperature T _{0, b1}, calculate and to use hull-skin temperature T _{0, b2}, thermal insulation material 37 etc. known thermal resistance value R _U0, and calculate and to use deep temperature T _{0, core}Calculate skin section thermal resistance value R _s+ R _t, thereby can obtain the skin section thermal resistance value R corresponding with the heat transfer characteristic of human body 2 _s+ R _tBecause deep temperature arithmetic element 441 is according to this skin section thermal resistance value R _s+ R _tCalculate deep temperature T _Core, thereby can not be subjected to the influence that the size difference etc. by human body 2 causes, can be according to the heat transfer characteristic of human body 2 computing deep temperature T exactly _Core

And, be this constant situation owing to utilize thermoflux from the deep of human body 2 to extraneous air, thermal resistance calculation unit 443 calculates the skin section thermal resistance value R of human bodies 2 _s+ R _t, thereby do not need as clinical thermometer in the past, to be used to eliminate the heating unit of the well heater etc. of hot-fluid, therefore can make the simple in structure of clinical thermometer 1.Can further promote the miniaturization of clinical thermometer 1 like this.And, owing to do not need in the past heating unit, thereby can promote the electric power of clinical thermometer 1 to save, even and clinical thermometer 1 to be attached to for a long time also be safe on the 2A of surface, thereby can improve the security and the usability of clinical thermometer 1.

(14) since thermometer body 3 and display device 4 constitute separately, and constitute and to communicate by Transmit-Receive Unit 35,41, thereby can with thermometer body 3 that human body 2 contacts on the component count that carries be suppressed to Min., can promote the lightweight and the miniaturization of thermometer body 3.Therefore, even, can not become burden yet, thereby can improve the portability of thermometer body 3 because thermometer body 3 attaches for a long time.And,, can further promote the lightweight and the miniaturization of thermometer body 3 by the control module 44 with thermal resistance calculation unit 443 and deep temperature arithmetic element 441 also is arranged in the display device 4.

Because Transmit-Receive Unit 35,41 constitutes by aerial coil 36,46 and carries out radio communication, thereby distribution etc. can not become obstacle, can improve the usability of clinical thermometer 1.

And because display device 4 forms Wristwatch-type, thereby operator 5 can be worn over visualization display part 42 on the wrist.Therefore, as present embodiment, show owing to can under the state of having the child who wants take temperature in arms, confirm body temperature, thereby can improve the operability of clinical thermometer 1.

(15) owing to contain skin section thermal resistance value R at storage part 45 internal memories _s+ R _t, thereby can in the measurement of bldy temperature step, read and use the skin section thermal resistance value R that is stored _s+ R _tTherefore, there is no need to carry out continuously measurement of bldy temperature preparation process and measurement of bldy temperature step, can calculate skin section thermal resistance value R in advance _s+ R _tTherefore, the usability of clinical thermometer 1 can be improved, and the Measuring Time of measurement of bldy temperature step can be shortened.And, because storage part 45 can be stored the skin section thermal resistance value R of a plurality of human bodies 2 _s+ R _t, thereby clinical thermometer 1 also can be used alternatingly for many people, can improve the convenience of clinical thermometer 1.

[the 7th embodiment]

Figure 22 shows the structured flowchart according to the clinical thermometer 1 of present embodiment.This clinical thermometer 1 has: the thermometer body 3 as temperature measurement unit that contacts with surface as the human body 2 (with reference to Figure 23) of live body, and the display device 4 that are provided with separately with thermometer body 3.

Here, expectation is that the sticking position of thermometer body 3 is set at skin temperature on the human body and is not easy to be subjected to extraneous air influence, the position of the forehead of measuring body surface temperature and the back side of head, chest, the back of the body etc. more stably.In the present embodiment, thermometer body 3 is attached to the chest of child's (human body 2).

And, what expect is, thermal insulation material 37 has size to a certain degree, make when thermometer body 3 is attached on the 2A of surface, do not allow to be subject to external environment influence from the deep of human body 2 by surface 2A and thermal insulation material 37 to the thermoflux of outside surface 30 is stable, for example can consider that thermal insulation material 37 forms and has more than or equal to the essentially rectangular shape of the size of 10cm in length and breadth.

In addition, by selecting the thermal resistance value R of suitable material with thermal insulation material 37 _U0Be set at predetermined value, therefore, the thermal resistance value of 33 thermal resistance value and thermal insulation material 37 is thermal resistance value R about equally from surface of contact 300 to outer surface sensor _U0And 32 thermal resistance value is to wait the predetermined value of setting according to the distance from surface of contact 300 to the position that is provided with intermediate sensor 32 from surface of contact 300 to intermediate sensor, in the present embodiment, is set to thermal resistance value R _U01

The sensor that temperature value is converted to resistance value shown in surface sensor 31, outer surface sensor 33 and intermediate sensor 32 can adopt in the first embodiment or temperature value is converted to sensor of magnitude of voltage etc.

And thermometer body 3 is except surface sensor 31, outer surface sensor 33 and intermediate sensor 32, and is shown in Figure 22 as described above, also has A/D converter 34 and Transmit-Receive Unit 35.

A/D converter 34 becomes digital signal to the resistance value of being changed or the analog signal conversion of magnitude of voltage in surface sensor 31, outer surface sensor 33 and intermediate sensor 32, and exports to Transmit-Receive Unit 35.Perhaps, can use the RF transducer replacement A/D converter 34 that utilizes the CR vibration.

Transmit-Receive Unit 35 has aerial coil 36, and the signal of the temperature value (resistance value or magnitude of voltage) that is converted to digital signal by A/D converter 34 is sent to display device 4 sides by electric wave.

Display device 4 constitutes portable Wristwatch-type as shown in figure 24, thereby the operator 5 who has the child that thermometer body 3 is housed in arms can be worn.Display device 4 is shown in Figure 22 as described above, have: and thermometer body 3 between the Transmit-Receive Unit 41 of receiving and transmitting signal, display body temperature measurement result's etc. display part 42, operating portion 43 from peripheral operation display device 4, the control module 44 of action of control display device 4, and the storage part (storage unit) 45 of the information that obtained from Transmit-Receive Unit 41 and control module 44 etc. of storage.
