Thoracoabdominal alternate pressing type cardio-pulmonary resuscitator

Abstract

The invention discloses a thoracoabdominal alternate pressing type cardio-pulmonary resuscitator which comprises a back plate, a support frame, a left support, a right support and two press devices. The press devices are used for thoracoabdominal-alternate-pressing cardio-pulmonary resuscitation. Telescoping mechanisms used for adjusting the interval between the press devices are arranged between the press devices. The press device used for pressing the chest is fixedly connected to the support frame. The upper ends of the left support and the right support are hinged to two ends of the support frame through hinges respectively. The lower ends of the left support and the right support are fixed with two ends of the back plate through fasteners respectively. The thoracoabdominal alternate pressing type cardio-pulmonary resuscitator belongs to the field of medical instruments, has two additional functions of lifting and pressing abdomens, overcomes the single thoracic-pressing resuscitation mode of existing cardiac resuscitators, promotes returned blood volume, increases cardiac preload and assists in increasing salvage success rate; by thoracoabdominal alternate pressing, flowing of blood towards important organs is facilitated, aortic pressure and central arterial pressure are increased, and blood supply and oxygen supply for the important organs are guaranteed.

Description

technical field [0001] The invention relates to a medical device, in particular to a chest and abdomen alternate compression cardiopulmonary resuscitation device. Background technique [0002] When the human body suffers from acute diseases or accidental injuries such as heart disease, high blood pressure, car accidents or drowning, it may cause shock and sudden stop of breathing and heartbeat. At this time, brain cells and organ tissues often cannot obtain enough blood and oxygen supply. resulting in hypoxia. In order to avoid the occurrence of hypoxia, cardiopulmonary resuscitation (CPR) must be performed continuously before and after the patient arrives at the hospital to maintain the patient's blood oxygen concentration and heartbeat. [0003] Traditional cardiopulmonary resuscitation relies on rescuers to perform artificial respiration and heart compressions on patients to help sick and injured patients maintain blood oxygen concentration. The effect is not good, so t...

AI Technical Summary

Problems solved by technology

[0003] Traditional cardiopulmonary resuscitation relies on rescuers to perform artificial respiration and heart compressions on patients to help sick and injured patients maintain blood oxygen concentration. The effect is not good, so the auxiliary cardiopulmonary resuscitation first aid device has also been developed

Existing cardiopulmonary resuscitation equipment adopts a single resuscitation method of pressing the chest, which does not fully consider the impact of the return blood volume on the resuscitation effect, and cannot further increase the return blood volume and central arterial pressure
