Abstract

Wrist watch with in-built sensors which measures and evaluates the biological parameters of a human being, e.g. blood pressure, pulse rate, body temperature and the like, and displays the biological time as a BIOLOGICAL WRIST WATCH. <IMAGE>

Description

The invention relates to a wristwatch with built-in Sensors, the important biological quantities of a human being, like blood pressure, pulse, body temperature etc. continuously measures, evaluates and displays as "biological time".

Known clocks show the "physical time". Your By appointment, the unit of time is the middle sun second, which is called second for short.

The "biological time" is a quantity that varies greatly depends on the behavior and lifestyle of an individual, on the other hand, "physical time" is independent of it Size.

By comparing the "physical time" with the "biological Time "a statement can be made how much time an individual in a time interval (e.g. lost or won in 24 hours) in his life Has.

A "biological wristwatch" must therefore be used on the basic values of the sizes of the individual to be measured be calibrated to related to the person concerned To be able to receive statements. These basic values must be caught up by a doctor.

The sensors are in the bottom plate of the watch case and / or built into the bracelet itself so that a constant acquisition of measured values is guaranteed.  

If a measured size exceeds the individual Value, as the default value, e.g. B. small light emitting diodes, preferably built into the dial of the watch, light up and warn of danger, which is inevitable connected is.

As an alarm system, e.g. B. also a small alarm clock is often built into the usual wristwatches, be used. It can be switched as required start up.

The "biological second" is made up of several components educated.

Blood pressure makes an important contribution: A rule of thumb says that the "systole value" of blood pressure the value

BD _s = 100 + age - 10) Hg mm

should have.

For a person aged 50 years:

BD _s = (100 + 50 - 10) Hg mm = 140 Hg mm = setpoint.

If you integrate the electrical impulses of the blood pressure sensor, this gives a target mean value as a reference to the setpoint.

Well, this value changes depending on excitement, physical exertion, fever etc. all the time, often from Minute to minute.

This makes the measured value a variable. He lets himself convert into clock pulses so that they make a variable time contribution deliver to the "biological second".  

Experience still teaches us that from the above Rule of thumb for genetic factor-dependent deviations can exist above but also below. There is People born a high or high have "low" blood pressure. The last one expresses itself - as is well known - in constant fatigue and fatigue. Modern medication can help here as needed.

The upward deviation is dangerous because it entire circuit. As a result, there are effects which life expectancy u. U. radically reduce can.

When calibrating a "biological clock", this is Effect takes into account that the age-dependent Setpoint. The individual then becomes register that it is e.g. B. daily more time of his life that it could have saved if it were one had undergone medical treatment.

Since the setpoint of the BD _{s is} age-dependent, the "biological clock" should be re-verified annually. This correction is intended, for. B. be made when changing the clock battery.

Another important biological variable is the pulse. Be The normal value for healthy people is between 60 and 80 Beats per minute. Nervousness, excitement, hectic pace, alcohol consumption etc. are factors that increase the normal value. There is a rapid heartbeat (tachycardia) is known as "palpitations".

So his contribution to the "biological second" is imperative be taken into account.

When calibrating the watch, you have to be careful that an increased pulse count still depends on the physical exertion (Walking, running, etc.) is also dependent. The pulse number  however, increases with a given load in a sportsperson Man less. There are tables that do this Capture context. You and the doctor decide on the Calibration value.

Body temperature also makes a contribution to "biological Second ". It is 36.7 in healthy people up to 37.5 ° C. In addition, one speaks of elevated temperature, the cause of which must be determined by a doctor. The calibration should be based on the normal temperature of the individual can be set.

So far only blood pressure, Pulse and body temperature indicated. Your overall impact is detected by appropriate switching technology.

An electronic circuit as a block diagram is shown as an example in Fig. 1. Miniaturization does not pose any problems since modern semiconductor chip technology is already available.

The basic idea of this circuit is:

The systole value of blood pressure and the value of the pulse will be detected here with a sensor. Then possibly follows Chopper, whose output pulses are both from the systole value depend on the pulse as well.

After integration you get a voltage, its mean value depends on blood pressure. This average is with a Setpoint value compared and when "exceeding" by a LED shown as "warning".

A counter records the number of pulses. It also comes with a Compare setpoint and exceeding with a LED indicated as "warning".  

The formation of the total "biological time" takes place in the Block where the temperature contribution from the sensor is included becomes. In addition setpoint adjustment and LED.

Block shows the "biological time".

Although the integrator value also depends on the number of the pulse depends, can nevertheless make a clear statement about it whether the "cause" is just blood pressure or Not. The pulse is on when the LED lights up responsible for.

The result can only be seen as a difference from the "physical Time ".

Analogously, however, a "biological wristwatch" both types of times show a continuous To be able to achieve comparison at any time.

Does a person read after z. B. 24 hours + 4 hours "biological Time ", he lived 28 hours instead of 24 hours. This 4 hours "extra time" does the same way of life 1460 hours out in one year. Pure loss time!

The aim of this invention is to give everyone a permanent To give self-control possibility. He should immediately go to the doctor when his "biological time" warns him.
