Embodiment Construction

[0011] Such as Figure 1~4 Shown, the present invention has pressing plate (1) and the negative pressure suction head (2) that is installed on it, miniature vacuum pump (3), displacement sensor (4), tension pressure sensor (5), central processing unit (6), Digital display (7), metronome (8), battery (9), handle (10), above-mentioned installation is firm connection. The displacement sensor (4) is connected with the A / D input end of the central processing unit (6), and the D / A output end of the central processing unit (6) is connected with the digital display (7). The internal components of the displacement sensor (4) are selected from U15 (AC650), and the interface circuit composed of U3 (AD574A), U2 (74HC244), U1 (74HC244), U13 (TLC5615), U14 (OP-07) and other components is connected with the The central processing unit is connected, and the displacement sensing element U15 converts the sensed voltage boosting range into a voltage change value and transmits it to the central ...

Abstract

The invention discloses an induction control type abdomen lifting and pressing cardio-pulmonary resuscitator comprising a negative-pressure adsorption mechanism, a lifting and pressing amplitude and displacement measuring and display mechanism, a pulling pressure measuring and display mechanism and a lifting and pressing frequency and quantizing beat promoting mechanism. When a miniature vacuum pump is turned on, negative-pressure suction heads are adsorbed on the abdomen skin of a patient to be rescued; a rescuer holds handles to lift up and press down according to frequencies prompted on a metronome, a displacement sensor measures and displays the lifting and pressing displacement, and a pulling pressure sensor measures and displays the lifting force and the pressing pressure. The cardio-pulmonary resuscitator has the advantages that the cardio-pulmonary resuscitator has favorable resuscitation effect on both respiration and circulation without mouth resuscitation, can ensure that the rescuer is not infected by diseases and avoid rib fracture, and is possible to successfully resuscitate by needing one rescuer.

Description

technical field [0001] The invention relates to a cardiopulmonary resuscitator, in particular to a cardiopulmonary resuscitator capable of displaying displacement, tension and pressure for lifting and pressing on the abdomen. Background technique [0002] At present, known cardiopulmonary resuscitators are all cardiopulmonary resuscitation devices that pressurize or depressurize the chest. [0003] The invention provides a sensor-controlled abdominal lifting and compression cardiopulmonary resuscitator. During the implementation of abdominal lifting and compression cardiopulmonary resuscitation, the rapid rise of abdominal pressure can promote the return of blood in abdominal organs containing 25% of the blood supply of the human body through the inferior vena cava. It flows into the right atrium, and at the same time keeps the aortic pressure higher than the right atrial pressure, so as to ensure that the hypoxic blood does not flow back into the heart. However, traditiona...
