Combination cardio-pulmonary resuscitation method for chest and belly

Abstract

The invention discloses a combination cardio-pulmonary resuscitation method for the chest and belly. A cardio-pulmonary resuscitator comprises a chest pressing device and a belly lifting and pressing device; when cardio-pulmonary resuscitation is conducted, the chest pressing device is placed on the chest of a salvee, the belly lifting and pressing device is placed on the belly of the salvee; the chest pressing device comprises a chest arched plate and a left foot lug; and the belly lifting and pressing device comprises a belly arched plate and a right foot lug. The cardio-pulmonary resuscitation method creatively proposes the combination cardio-pulmonary resuscitator for the chest and belly, and the resuscitator can simultaneously establish manual blood circulation and respiration circulation through pressing the chest and lifting and pressing the belly by a stamping mode, thereby realizing cardio-pulmonary resuscitation; and simultaneously, the hand pressing mode in the traditional cardio-pulmonary resuscitation method is abandoned, so that the physical strength of medical care personnel is greatly saved and labor intensity is reduced, and the medical care personnel can perform salvage operations continuously for a long time, thereby improving the success rate of cardio-pulmonary resuscitation.

Description

technical field [0001] The invention belongs to the medical field, and in particular relates to a chest-abdominal combined cardiopulmonary resuscitation method. Background technique [0002] It is well known to medical staff that the traditional CPR method uses a 30:2 ratio of chest compressions and artificial respiration. The principle of cardiopulmonary resuscitation (hereinafter referred to as CPR) mainly works through two mechanisms: "heart pump" and "chest pump". The left ventricle ejects blood to the aorta; when the thorax and heart relax, there is negative pressure in the thoracic cavity, and blood near the thoracic cavity flows into the thoracic veins and cardiac cavity. The pressure difference between the aorta and the right atrium is the main factor determining the cardiac perfusion. Increased positive thoracic pressure can increase aortic pressure, and increased pleural negative pressure can promote venous return and myocardial perfusion. The lower the negative t...

AI Technical Summary

Problems solved by technology

However, the success rate of CPR rescue is very low, and the rescued people who are rescued successfully are also prone to serious neurological sequelae, which is related to the limitations of CPR:

[0004] 1. The traditional chest compression resuscitating cardiopulmonary method divides the blood circulation and breathing process into two independent parts. When the chest is pressed, only blood flows and the lungs have no gas exchange. During artificial respiration, there is no blood flow in the lungs, so ventilation The / blood flow ratio is seriously unbalanced. Even if there is blood flow through vital organs, hypoxic damage cannot be guaranteed. Brain hypoxia is the main cause of neurological sequelae

Therefore, CPR usually requires the cooperation of multiple people, which is difficult to achieve in pre-hospital emergency

[0005] 2. The amount of blood pumped by chest compressions is low, which is not enough to supply blood and oxygen to all organs of the body. Long-term chest compressions consume a lot of physical strength for the rescuer, and the frequency and depth of compressions will decrease, and the effect of cardiopulmonary resuscitation will also decrease. drop with it

[0006] 3. The process of pressing will bring different degrees of damage to the rescued person, such as rib fracture caused by excessive force during pressing, and the broken end of the fracture can stab the lungs and heart causing secondary damage, and if the rescued person already has a heart Injury, when pressing, it will inevitably increase the damage and even cause heart rupture. If the pressing position is low, it can directly lead to rupture of abdominal organs, especially the liver, and this kind of liver rupture is difficult to diagnose in the early stage, which seriously threatens the life of the rescued person.
