Description

SOS cardiopulmonary resuscitator

technical field

The invention relates to a first aid device, in particular to an SOS cardiopulmonary resuscitator.

Background technique

Sudden death is a clinical syndrome, which refers to the sudden unexpected non-artificial death of a person who seems to be healthy or whose condition has basically recovered or stabilized. As we all know, sudden death is very easy to occur after excessive fatigue, strenuous exercise or large emotional fluctuations, and the places where sudden death occurs are mostly sports grounds (including marathon sites), stations, airports, docks, communities, schools, gymnasiums, bathing beaches and other public places . Sudden death rescue methods, that is, cardiopulmonary resuscitation methods, are as follows: the first is to tap the precordial area—knock three times with a fist on the precordial area, and for patients who have just suffered cardiac arrest, some of them can resume beating; Cardiac compression (percussion on the front of the heart if it stops beating)—the patient lies supine on a hard bed or the ground, the operator places the heel of the left back palm on the lower half of the patient's sternum, and places the right palm on the back of the left hand First, press rhythmically with both hands, and use the force of the body to press down rhythmically 100-120 times per minute to avoid rib fractures caused by excessive force; the third is mouth-to-mouth artificial respiration (usually done together with chest compressions) , press the heart 30 times, perform mouth-to-mouth artificial respiration 2 times) - the operator supports the patient's neck with one hand, tilts the head back as much as possible, and keeps the airway unobstructed; pinches the patient's nostrils with the other hand, and aligns the patient's mouth Blow out hard, 12 times per minute. The golden rescue time for sudden death is 4-6 minutes, generally no more than 10 minutes. The above-mentioned rescue method is indeed effective for some patients who have been rescued in time. However, it is not only laborious to perform chest compressions for a long time, but it is also difficult for non-professionals to master the appropriate compression pressure. The effect may not be good if the force is low. If the force is too high, the patient's ribs may be fractured; Sickness, artificial respiration also has the risk of bringing health hazards to rescuers. Therefore, designing a kind of SOS cardiopulmonary resuscitator is a technical problem to be solved at present.
