Abstract

Many people die because they fail to recognise in good time that the stress on the heart and blood circulation has reached or exceeded the maximum permissible, critical personal stress level. This applies not just to ill people but also to many others who believe they are healthy. The measurements of blood pressure and other parameters are almost always carried out under the conditions and stresses which differ greatly from the real critical values. The present blood circulation monitoring apparatus continuously monitors the human blood pressure and pulse rate and signals 1. that the maximum permissible blood pressure and pulse rate values, and 2. the critical limits for blood pressure, pulse rate and pulse failure are reached or exceeded. The individual can immediately limit or eliminate the stress or, if necessary, consult a doctor. The present apparatus can be produced in a conventional laboratory design or in a micro form, e.g. in conjunction with a wristwatch.

Title: A Blood Circulatory Control Device.

(Technical name) Application- The invention relates to a blood circulatory area : control device that continuously monitors blood pressure and pulse and the achievement of the maximum permitted as well as the critical measured values of the blood pressurea, Pulse and dangerous irregularities in the bloodstream.

This blood circulation control device is primarily for those with severe heart disease, for people with high or low blood pressure and with irregularities in the blood circulation, but also for apparently healthy people who work in their jobs, in sports or heavy loads of all kinds are exposed in normal life.

Purpose: As things stand now, a lot of people die because of them do not recognize in time that the strain on the heart and blood circulation is the highest permitted and critical personal stress value reached, or has exceeded.

This is true not only with the sick, but also with many others who believe they are healthy.

The blood pressure and other measurements are almost always with the conditions and loads that are far from the really critical values. purpose this invention is to signal in time that in the first place the permitted ones masimal values of blood pressure, heart rate and, in the second row, the critical ones Limits of blood pressure, pulse and pulse failure reached or exceeded are that the person limits the load equally, exposes it, event. visit the doctor.

State of the art The blood pressure measurements change from case to case technique : performed with the cuff system (pressure equalization system).

Continuous measurements of blood pressure are not possible here.

This measurement is an experimental method in which the dynamic Blood pressure limits are controlled. You are already with the principle a high personal burden, which is very large even if it is qualified medical staff.

The mistakes are all the greater if unskilled people do it, E.g. patients themselves, as it often happens today.

The pulse measurements are always personal from case to case carried out so that one counts pulses for a certain time interval and these from a Minute converted.

The various devices that are on the market today measure time a pulse and convert it to a minute.

In one minute you get different information about the irregularity correspond to the pulses.

The dangerous pulse failure is rarely checked and when it is, then personally.

All these measurements are carried out discontinuously, unfortunately not at that time, when the load is so great that the readings of the blood circulation are critical.

Task: The invention is based on the task of a blood circulation control device to develop which is attached to a part of the human body and is continuous Checks the level of blood pressure, pulse and pulse failure and displays it on request and signals that the maximum permitted and critical measured values have been reached.

Solution: According to the invention, this object is achieved in that with an inductive, capacitive, resistive, optical, nuclear or other rem Donor which is placed on a part of the body, e.g.

Hand, is attached, the pulse characteristics recorded and in the input module M 1 is evaluated.

The starting position is set up in module M 2 and the volume changes of the body part are compensated in module BB 3.

In module M 1-1, the first (yt) and the second lerivation (y ',) of the rising part of the pulse characteristic is carried out.

When this second derivation is reached, a short-term release is given given for the maximum amplitude of the pulse characteristic on module M I-2.

The output signal of the module M I-2 is firstly Zlim module M 1-3 supplied, where the width of the mamaximum amplitudes the time t2 are stored, second to module M I-8, where the number of pulses per time t2 is calculated.

After the time "t2" has elapsed, the sum of the maximum amplitudes becomes the pulse characteristic from module X 1-3 into module M I-4 at the same time as the signal of module M I-8 initiated.

In module M I-4, the division of the sum of the values from module M I-3 executed by the signal from module M I-8 and the average Measured value the upper limit of the blood pressure is determined and a second t2 time period is stored.

The output signal of module X I-4 is fed into a comparison module (M I-5) with an adjustable setpoint of the maximum permitted upper limit of the Blood pressure and in a comparison module (M I-6) with an adjustable setpoint the critical upper limit of blood pressure.

Reaching or exceeding these values is indicated.

This task can also be done with a module with two setpoints will.

The access signal of the module M I-4 can be read off.

In Part II the same task is given for the lower limit of blood pressure executed.

In Part III, in module M III-1, the integral # l of the area between two second derivations executed and fed into the module M III-3, where this Measured values are saved in time t2.

After the time t2 has elapsed, the sum of these measured values is transferred from module M III-2 simultaneously with the signals from module M I-8 of part I in module M. II 1-4 supplied, where the average measured value is calculated and the second time period t2 is saved.

This output signal is used in the comparison modules M IIT-5, 6, 7, 8 evaluated and when the allowed maximum and critical values of the upper limit, as well as the allowed minimum and critical values of the lower limit of blood pressure signals.

The output sign # -l of the module M III-4 can be read in part IV is allowed and the critical limit of the pulses is implemented. The number of pulses becomes read on module M 1-8 in part I.

In parts V and 71, the unauthorized failure of the pulses is monitored.

In the module M V-1 is the signal from the module 'M 1-8 (number of pulses supplied in time t2) and time t2. The time of a pulse is calculated here.

The output signal is fed to the modules M V- '»and M JI-2, where the maximum and minimum time interval is set. On this time interval the time of each pulse is compared.

If the comparison time is exceeded, the module M V-3 or M VI-2 a pulse, which switches a time module on and at the same time this pulse is stored in module X V-5 or M VI-4.

After 1 minute of the time modules M V-4 and M VI-3, the number becomes the irregular impulses are transferred to the module M V-6 or M V1-5, where the measured values evaluated and saved for one minute.

Reaches or exceeds the number of in a time of 1 minute This is signaled if irregular impulses exceed the setpoint of the module M V-6 or M VI-5.

The number of irregular impulses can be seen on the module M V-6 or M Read VI-5.
