Problems solved by technology

At present, in the process of cardiopulmonary resuscitation, medical workers at home and abroad only pay attention to the position, frequency and strength of cardiac compression during cardiopulmonary resuscitation, but there is no better way to increase venous return to the heart and improve circulation efficiency. Increase the frequency and intensity of heart compressions to maximize the efficiency of CPR

Abstract

The invention provides a cardiopulmonary resuscitation auxiliary device which is characterized in that the seat of the internal cavity is provided with an oxygen supply end communicated with an oxygen supply tube, an air supply expiration end communicated with a patient mask or throat air duct, and an air evacuation end communicated with the air; the oxygen supply end is provided with a one way control valve and a first one way valve film; and the air evacuation end is provided with a second one way valve film. During the implementation of the cardiopulmonary resuscitation, while the chest wall elastically retracts after being pressed, the gas suction amount in lungs is blocked by the one way control valve at intervals, thereby enhancing the negative pressure of the chest cavity, increasing the returned blood volume and the cardiac ejection volume, ensuring the blood supply to important organs, such as the cardiac coronary artery, brain, liver, kidneys and the like, and increasing thesuccess ratio of cardiopulmonary resuscitation. The invention has the advantages of simple structure, convenient operation and sensitive operation, thereby being an ideal cardiopulmonary resuscitation auxiliary device.

Description

technical field [0001] The invention provides an auxiliary device, in particular a cardiopulmonary resuscitation auxiliary device, which belongs to the technical field of medical instruments. technical background [0002] In recent years, with the continuous research on cardiopulmonary resuscitation by domestic and foreign medical workers, it has been found that maintaining blood flow and necessary lung gas exchange during cardiopulmonary resuscitation is the key to the success of cardiopulmonary resuscitation, while maintaining the internal circulation of the circulatory system The blood flow of the heart is an important condition to ensure the blood perfusion of vital organs and the normal function of the heart, lung, brain, liver, and kidney. Increasing the return blood volume of the lungs and systemic veins is to maintain left and right cardiac output, establish blood circulation, and ensure tissue oxygen supply. An important means to balance oxygen consumption and impro...
