A chest and abdomen combined cardiopulmonary resuscitator

Abstract

The invention discloses a combined thoracic and abdominal cardiopulmonary resuscitation device. The combined thoracic and abdominal cardiopulmonary resuscitation device is characterized by consisting of a chest compressing device and an abdomen uplifting device; during implementation of cardiopulmonary resuscitation, the chest compressing device is placed on the chest of a rescued person; the abdomen uplifting device is placed on the abdomen of the rescued person; the chest compressing device comprises a chest arc plate and a left foot supporting lug; abdomen uplifting device comprises an abdomen arc plate and a right foot supporting lug. The invention innovatively provides the combined thoracic and abdominal cardiopulmonary resuscitation device, and the combined thoracic and abdominal cardiopulmonary resuscitation device compresses the chest and uplifts the abdomen in a pedaling way, and can simultaneously establish artificial blood circulation and respiratory circulation, so that the cardiopulmonary resuscitation can be achieved; meanwhile, an arm compressing way in the conventional cardiopulmonary resuscitation method is discarded, so that the physical strength of medical staff is significantly saved, the labor intensity of the medical staff is significantly reduced, thus the medical staff can perform sustained rescue for a long time, and therefore the success rate of the cardiopulmonary resuscitation is improved.

Description

technical field [0001] The invention belongs to the medical field, in particular to a chest and abdomen combined cardiopulmonary resuscitator. Background technique [0002] It is well known to healthcare workers that traditional CPR involves a 30:2 ratio of chest compressions and rescue breaths. The principle of cardiopulmonary resuscitation (hereinafter referred to as CPR) mainly works through two mechanisms: "heart pump" and "chest pump": when the chest wall is pressed, there is positive pressure in the chest, and at the same time, the heart is squeezed by the chest wall, and the right ventricle ejects blood to the lungs. The left ventricle ejects blood to the aorta; when the thorax and the heart relax, there is negative pressure in the thoracic cavity, and the 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 that determines the perfusion of the heart. The inc...

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 pumping volume of chest compressions is low, and the myocardial perfusion decreases during extrusion, 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 compression frequency and depth will decrease, and the effect of cardiopulmonary resuscitation will also decrease

[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.
