Description

A cardiopulmonary resuscitation compression and breathing assistance device for respiratory emergency

technical field

The invention relates to the technical field of medical equipment, in particular to a cardiopulmonary resuscitation compression and breathing assistance device for respiratory emergency.

Background technique

Cardiopulmonary resuscitation, also known as CPR, is a rescue measure for heartbeat and respiratory arrest, that is, to use chest compressions or other methods to form a temporary artificial circulation and restore the heart's own beating and blood circulation, and to replace spontaneous breathing with artificial respiration and restore autonomy. Breathe, achieve the purpose of recovery and save life. It can make the patient's heart, brain and vital organs of the whole body obtain the minimum emergency oxygen supply after the patient's cardiac arrest, and provide the most basic life support.

Cardiopulmonary resuscitation is suitable for circulatory arrest caused by various reasons, including cardiac arrest, ventricular fibrillation, and extremely weak heartbeat. If the operation is carried out for a long time, it is easy to cause the medical staff to be physically exhausted, and it is easy to ignore the small changes in the pressure and position of the chest compression, resulting in inaccurate positioning of the chest compression site, posture deformation, etc., thereby causing safety hazards.

The diseases mainly treated by the Department of Cardiology include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, myocardial infarction and other cardiovascular diseases. When these patients seek medical treatment, they often encounter emergencies such as cardiac arrest and respiratory arrest. At this time, the doctors present need to carry out emergency rescue on the spot, usually performing cardiopulmonary resuscitation first aid measures to restore the patient's heartbeat and breathing, and then send them to the emergency room Or the operating room for treatment, but sometimes when only one doctor is present, it is very inconvenient to perform chest compressions and artificial respiration at the same time. Moreover, it is easy to cause direct infection or potential cross-infection of the disease, endangering the health of medical staff and patients.
