technical field

The utility model relates to the technical field of medical devices, in particular to a cardiopulmonary resuscitation device for emergency first aid.

Background technique

Cardiopulmonary resuscitation is a technique of rescue with artificial respiration and chest compressions when a patient stops breathing and is in cardiac arrest. Cardiopulmonary resuscitation is a well-known term. It is an emergency technique. Of course, when a sudden cardiac arrest occurs, it must be performed immediately. It is necessary to seize the precious time to save people's lives and avoid the patient's brain and body. Organs are irreversibly damaged.

The golden rescue time for cardiopulmonary resuscitation is 4 to 6 minutes after the heartbeat and breathing stops. If the resuscitation is successful, the patient's nervous system has a better prognosis. Otherwise, serious sequelae will remain even if the heartbeat is restored, which is so short-lived. Therefore, family members of patients with heart disease often know CPR so that they can perform CPR on the patient in time, but CPR requires 100 to 120 chest compressions per minute. /min, the physical strength of family members is relatively high, and the frequency of cardiopulmonary resuscitation will decrease in the later stage, reducing the probability of re-pacing the heart, resulting in the failure of rescue. A cardiopulmonary resuscitation device that can replace manual chest compressions is needed. , in order to ensure the frequency of chest compressions and improve the success rate of CPR.
