Cardiopulmonary resuscitator

Abstract

The invention relates to a cardiopulmonary resuscitator, in particular to a cardiopulmonary resuscitator capable of stimulating abdominal respiration, comprising a micro control unit (MCU), a first pressing unit and a second pressing unit, wherein the first pressing unit comprises a first motor driving circuit, a first motor, a first connecting rod and a first pressing head; the MCU outputs a first control signal to the first motor driving circuit; based on the first control signal, the first motor driving circuit drives the first motor to rotate in order to drive the first connecting rod and the first pressing head connected at the tail end of the first connecting rod to move in a reciprocating manner so as to press the breast of a patient; the second pressing unit comprises a second motor driving circuit, a second motor, a second connecting rod and a second pressing head, and the MCU outputs a second control signal to the second motor driving circuit; based on the second control signal, the second motor driving circuit drives the second motor to rotate to drive the second connecting rod and the second pressing head connected at the end part of the second connecting rod to move in a reciprocating manner so as to press the belly of the patient; the second pressing head is detachably attached at the abdomen of the patient; the first and second pressing units work asynchronously and collaboratively; when the first pressing head of the first pressing unit executes the pressing operation, the second pressing head of the second pressing unit executes the lifting operation; and when the first pressing head of the first pressing unit executes the lifting operation, the second pressing head of the second pressing unit executes the pressing operation. As the patient is stimulated to perform abdominal respiration while the breast is pressed, the cardiopulmonary resuscitator can be used for effectively improving the respiratory effect and increasing the treatment efficiency.

Description

technical field [0001] The invention relates to a cardiopulmonary resuscitator, in particular to a cardiopulmonary resuscitator with the function of abdominal compression. Background technique [0002] Cardiopulmonary resuscitation is a technique that combines artificial respiration and external cardiac compression for first aid when breathing stops and heartbeat stops. The current cardiopulmonary resuscitator mainly presses the patient's chest repeatedly to make the heart beat again. At the same time, it cooperates with the ventilation device to blow oxygen from the patient's mouth to the patient's lungs. The external compression promotes blood exchange from the lungs to the brain. The body and the whole body, so as to maintain the survival of brain cells and organ tissues. [0003] A cardiopulmonary resuscitator is known, which controls the motor drive circuit through the MCU, and the motor is controlled by the motor drive circuit. The output end of the motor is connected...

AI Technical Summary

Problems solved by technology

[0004] One of the shortcomings of existing cardiopulmonary resuscitators is that they do not effectively use abdominal breathing, so the treatment effect is relatively poor

Another shortcoming of the existing cardiopulmonary resuscitator is that the pressure and depth of the chest can not be controlled, often causing the patient to damage soft tissues or even internal organs due to excessive compression
