Description
Technical field：
During the present invention is medical device technology product scope：A kind of instrument for measuring human blood-pressure situation.It is to use
Air pressure promotes corrugated tube to promote the liquid in sealed glass tube to be flowed up and down to measure blood pressure again, and is equipped with the electronic surveying heart
The medical device product of rate and a kind of electromechanical integration for showing.
Background technology：
In the product of measurement human blood-pressure situation：A kind of is the mercurial sphygmomanometer being usually used for many years.Its method
It is：By to the sleeve bag being banded on human body arm, sleeve bag inflation being given by pressure air-inflating tube with pressurization inflatable ball, in sleeve bag
Air pressure promotes the hydrargyrum in mercury boxes to rise or fall along the graduated hollow glass tube of band by connectivity trachea again.Such people
On body arm arteriotony bounce situation the hydrargyrum in glass tubing will be promoted to move up and down, hydrargyrum movement situation and
It is provided with the glass tubing of rule and shows.Appropriate increase air pressure or aerofluxuss blood pressure lowering will show the high pressure of human blood-pressure
With the blood pressure conditions of low pressure so as to the blood pressure for measuring human body is next.This method is simple, stable, effective, but hydrargyrum is also with regard to hydrargyrum
A large amount of uses or it is discarded can bring pollution to ecological environment, be unfavorable for environmental conservation.
Also one kind is gauge outfit formula sphygomanometer：It is to promote metal bellowss with air pressure, promotes gear by corrugated tube,
Drive indicators turn to measure blood pressure by gear shift by gear again.As pointer is that rotation indicates blood pressure data,
The mode for moving up and down during measurement with mercury column in traditional mercurial sphygmomanometer in glass tubing does not meet, and visual effect is not
Together, it has not been convenient to observe.The degree of accuracy of this sphygomanometer is low in addition, and error ratio is larger, uses and blood pressure conditions generally as carrying
Reference use.
Another is electric sphygmomanometer：Its method is to being banded on human body arm by electric gas-filled method
Sleeve bag inflation, the air pressure situation tucked inside the sleeve in bag are sent to the signal of telecommunication in microprocessor to enter by the blood pressure sensor being arranged in sleeve bag
Row is processed, then the blood pressure data for processing is passed through electronic display screen displays out.It is this it is electric gas-filled also can progressively bleed,
So as to the number of times i.e. heart rate for measuring the high pressure of human blood-pressure, one point of kind of low pressure and heart is beated.The advantage of this method is
The sub- display of blood pressure of number is directly perceived, but numeral fluctuation is larger, and accuracy rate is relatively low, is generally used to make as the reference of human blood-pressure situation
With.
The content of the invention：
All it is also to change to measure making for blood pressure, hydrargyrum i.e. hydrargyrum with regard to the height of mercury column with hydrargyrum in mercurial sphygmomanometer
With or discarded can bring pollution to ecological environment.The present invention is replacing the use of hydrargyrum with liquid.
Technical scheme proposed by the present invention is：Can be stretched with elasticity with what air pressure promotion metal or rubber carbon moulding material were made
Contracting and be enclosed in a corrugated tube filled in the tubular bobbin of liquid as air pressure size carries out telescopic displacement, then by ripple
The telescopic displacement of pipe promotes the liquid in bobbin to be provided with the glass tubing of blood pressure rule by connection along the outside that attenuates to extrude
The principle of gas make the liquid in glass tubing in glass tubing can as the size of air pressure is flowed in glass tubing up and down, and
The blood pressure that human body is measured on blood pressure rule comes.The following of glass tubing is fully sealed with the UNICOM's part equipped with liquid, glass
The top of pipe passes through a breather and gas storage letter is also fully sealed.Heart rate sensor is additionally provided with to heart rate shape in sleeve bag in addition
Condition is measured, and the heart rate data of measurement is sent to the signal of telecommunication on heart rate digital display by electric wire and is shown.
The technical solution adopted for the present invention to solve the technical problems is：
In an openable rectangular box, a mark mercury column and pressure are provided with the upper lid of box
Blood pressure rule, rule be provided with adjustment screw can adjust rule move up and down for proofread rule zero point with
The correspondence position of fluid level light bright spot zero point in glass tubing.A glass for flowing up and down for liquid is provided with the centre of rule
Glass pipe, in order to the top for preventing the evaporation of liquid, glass tubing is mutually sealed with a breather and a gas receiver with negative pressure
Connection, by outside and inner when negative pressure gas receiver had not only prevented the evaporation of liquid but also protected liquid to be flowed in glass tubing up and down
The obstruction of face air pressure and impact.The following of glass tubing is provided with the three-way elbow of an energy printing opacity, the upper shed of three-way elbow and glass
The glass seal of tube couples, and another fluid connection pipe excessively all of three-way elbow is mutually sealingly connected with the liquid storage cylinder equipped with liquid,
Below three-way elbow, general one piece of transparent glass jam is sealed.Laser fulgurite, laser are provided with below glass jam
The light that fulgurite sends is irradiated on liquid by glass jam, due to liquid light conduction can in glass tubing liquid column
A light bright spot is formed above, is so easy to the correspondence position in liquid column plane and blood pressure rule in sight glass pipe.Glass
Liquid in glass pipe passes through fluid connection pipe and liquid storage cylinder by three-way elbow can carry out phase under the principle effect of UNICOM's gas
Mutually flow.Liquid can be it is transparent can also be coloured.A following sealing top is fixed on the inside of liquid storage cylinder
The corrugated tube made with metal or rubber carbon moulding material of ventilation, among the corrugated tube of sealing is fully immersed in the liquid of liquid storage cylinder,
A blow vent is provided with above corrugated tube and is connected with the sleeve bag being banded on human body arm by a connectivity trachea.Glass
Gas part and liquid below part above inside pipe all fully seals, and gas and liquid are carried out in glass tubing
Do not affected by outside air pressure during lower flowing.
When bag of tucking inside the sleeve is bundled in blood pressure measurement is carried out on human body arm, give sleeve bag by pressure air-inflating tube with pressurization inflatable ball
Inflating pressure.Air pressure in sleeve bag can promote the corrugated tube being enclosed in liquid storage cylinder to make corrugated tube with gas by connectivity trachea
The change of pressure is stretched, corrugated tube it is flexible can extrude the liquid being enclosed in liquid storage cylinder make liquid by fluid connection pipe and
Three-way elbow is flowed under the principle effect of UNICOM's gas in glass tubing up and down.As three-way elbow is arranged below laser electricity
Pipe, the light that laser fulgurite sends are irradiated on the liquid column in glass tubing by glass jam, and due to the conduction of light, meeting exists
A light bright spot is formed in glass tubing in the plane of liquid column, the situation that liquid column light bright spot is moved up and down in glass tubing is also
It is the situation of human blood-pressure, can be measured by blood pressure rule.
Turn on the power switch, the heart rate sensor being arranged in sleeve bag can be measured to the heart rate of human body and handle is measured
The heart rate data for coming is sent on numerical heart rate display and shows.Heart rate detection sensor, laser fulgurite in sleeve bag, heart rate
The parts such as numerical monitor are by the on and off switch control power supply on lid on box by the set of cells being arranged in box lower cover.
In order to bind together wire intertwist, the transmission electric wire of heart rate signal and connectivity trachea.
