SU986421A1 - Device for external contrpulsations - Google Patents

Description

The invention relates to a medical technique, namely, apparatus for treating cardiac patients.

A device for external counterpulsation is known, comprising a control unit with synchronization from an ECG and a man-i JETC.

However, this device does not ensure the possible directional effects on hemodynamics.

It is also known to have an external counterpulsation device comprising a rhythm-cardiometer, a cardiac synchronizer, a control unit, an overpressure unit with cuffs, and a vacuum action unit with vacuum containers 2.

However, this device does not provide the range of effects required for a targeted effect on hemodynamics depending on the patient's disease.

The aim of the invention is to increase the efficiency of treatment of cardiac patients by expanding the range of effects on the body.

The goal is achieved by the fact that a device for external co-impulse containing a rhythm-cardiometer, a cardiac synchronizer, a control unit, a unit

overpressure, the mannets and the vacuum unit with vacuum containers are equipped with two venous harnesses and an intensive 5-cuff cuff with corresponding regulating units.

The drawing shows the block diagram of the device for external counterpulsation.

The device for external counterpulsation contains a program unit block 1, a control unit 2, an oscilloscope 3, an intensive action unit 4, a gauge of excessive 5 and vacuum 6 pressure, 5 blocks of vacuum 7 and excess B pressure, a gauge pressure meter 9 and venous 10 pressure, a venous bundle unit 11 , intense cuff 12, cuff entry

20 13 venous bundle, the entrance to the vacuum tank 14, the entrance to the cuff 15 of overpressure, the extractor 16 R-wave and the cardio-synchronizer 17.

25 The device works in the following way.

In accordance with the table below, the doctor chooses a different type of exposure, depending on

30 types of the patient's disease and sets the selected program on the program block 1. The R-wave extractor 16 generates trigger pulses synchronous with the ECG R-wave. The generated pulse goes through the cardiac synchronizer 17 to the control unit 2, where the control and correction signals from the program block 1 and the arterial and venous pressure meters 9 and 10 also arrive. The arterial and venous pressure meters 9 and 10 are systems for constant pressure monitoring The patient during the operation of the device and according to their indications is corrected in the duration and phase of the control pulse from the control unit 2 depending on the changes in the hemodynamics of the patient. Visual Monitoring of the impulse of the R-wave, changes in arterial and venous pressure, pulses of overpressure and vacuum. effects are carried out using an oscilloscope g. The formed impulses from the control unit are supplied to the corresponding units: intensive action unit 4, overpressure unit 8, vacuum action unit 7, venous harness unit 11, which leads to a direct impact on the patient through intensive exposure cuffs 12, overpressure 15, vacuum action 14, or the cuffs 13 of the venous cord, and on the block 11 of the venous cord enters an operative impulse from the control unit 2 in order to obtain a preemptive clamping of the venous bed with a pressure equal to or much greater venous pressure of the patient, it is necessary to obtain a selective effect on both arterial and venous bed to the patient and to reduce the flow to the heart and increase the venous flow of arterial blood. The proposed device for external counterpulsation will allow you to increase the effectiveness of treatment of cardiac patients by targeting the hemodynamics of the patient.
