Description

Portable cardiopulmonary resuscitation protection device

Technical Field

The invention belongs to the technical field of medical auxiliary instruments, and particularly relates to a portable cardio-pulmonary resuscitation protection device.

Background

Sudden cardiac arrest refers to sudden and non-exogenous sudden death in a short time, the number of sudden cardiac death in China reaches 54.4 thousands, and timely and effective cardio-pulmonary resuscitation (CPR) can effectively prevent the development of the illness state of patients suffering from sudden cardiac arrest and save the lives of patients. Practice proves that the effective rescue of CPR is carried out on a patient within 4min after the patient has sudden cardiac arrest, the gold time for saving life is provided, and the survival rate of the patient can be 49-75 percent higher; if the rescue is not carried out in time, the survival rate is reduced to 7-10% every minute of delay. While about 70% of cardiac arrest occurs out of hospital, 97% of out-of-hospital cardiac arrest (OHCA) events are first witnesses before professional rescue teams arrive on site, and therefore, timely and effective CPR on OHCA patients by first witnesses is of great value.

However, the proportion of the first witnesses to perform CPR on the patient with cardiac arrest outside the hospital is only 2% -5%, and the CPR implementation rate is only 4.5% even in large and medium-sized cities. The reason why the CPR administration rate is low is that the CPR popularization rate is low, and there are concerns about factors such as people's disputes due to unexpected events such as rib fractures caused by administration of CPR. After a lot of research and development, the lack of an auxiliary first-aid safeguard device is one of the main factors obstructing the rescue will of CPR, so that the provision of a CPR protector and the reduction of accidental damage caused by the implementation of CPR are of great significance for improving the rescue will of the first witness, improving the CPR implementation rate and improving the survival rate of OHCA patients.
