Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a defibrillation device and a defibrillation method capable of performing cardio-pulmonary resuscitation.
Background
Sudden cardiac arrest refers to the sudden termination of the ejection function of the heart, the disappearance of the aortic beating and heart sound, and the termination of life caused by severe ischemia and anoxia of vital organs (such as the brain). Sudden cardiac arrest is more and more common in modern society, and besides some problems of the heart, the work pressure, the living pressure, unreasonable living work and rest, unhealthy diet, long-term lack of exercise and the like are all one of the fierce murders causing the sudden cardiac arrest. In the rescue of patients with cardiac arrest, the combined use of an Automatic External Defibrillator (AED) and cardiopulmonary resuscitation (CPR) can improve the survival rate of patients to a greater extent.
An Automatic External Defibrillator (AED) is a portable medical device that diagnoses certain arrhythmias and delivers shock defibrillation, and is a medical device that can be used by non-professionals to rescue a cardiac arrest victim. During cardiac arrest, defibrillation and cardiopulmonary resuscitation are performed on a patient by using an AED within the 'gold 4 minutes' of the optimal rescue time, which is the most effective method for stopping sudden death. Meanwhile, the AED is set in a self-contained program, and after electric shock or when the AED diagnoses the heart rhythm and does not need electric shock defibrillation, the AED can prompt rescuers to carry out cardio-pulmonary resuscitation by voice.
The final goal of cardiopulmonary resuscitation is to increase the perfusion blood flow of the heart and brain of a patient with sudden cardiac arrest, avoid the heart and brain from entering an irreversible death state, and gradually restore the organ work function of the heart and brain. The continuous and effective external chest compression is necessary, rapid and powerful, and is uninterrupted as much as possible, because excessive compression interruption can interrupt coronary artery and cerebral blood flow, and the resuscitation success rate is obviously reduced. Unfortunately, conventional free-hand CPR involves very little blood flow to the heart and brain, difficult control of compression depth, gradual exhaustion of rescuers by long-term manual compression, and difficulty in sustaining, and when used in conjunction with automated external defibrillator rescue, rescuers have to stop cardiopulmonary resuscitation before shock to avoid accidental injury.
Currently, excellent AED products and cardiopulmonary resuscitation devices have been developed. However, the two products are independent, and when the combination is used, if the cardiopulmonary resuscitation instrument is continuously used, the AED can acquire interfering electrocardiosignals to influence the issue of AED defibrillation instructions; if the correctness of the AED heart rhythm analysis is ensured, human intervention is still needed, and the use of the cardiopulmonary resuscitation instrument is stopped, so that the cardiopulmonary resuscitation effect is weakened, and the rescue success rate of a patient is reduced.
AED products on the market still need to be matched with manual cardiopulmonary resuscitation at present, the manual cardiopulmonary resuscitation has the phenomenon of inaccurate pressing depth and pressing frequency, and continuous high-frequency pressing can gradually exhaust rescuers and reduce the rescue effect; during electric shock, the rescuers need to be far away from the patient to avoid accidental injury, so that continuous cardiopulmonary resuscitation is interrupted, and the rescue effect is reduced.
