ABSTRACT:
This invention relates to a manual pressing and automatic air breathing cardiopulmonary resuscitation first-aid device, mainly comprising a manual pressing shaft, a pump, an air storage tank, a height-adjustable stand, an air control valve and a mouth-nose breather. In operation, the manual pressing shaft is pressed to cause the pump to compress downwards such that air is compressed into the air storage tank and temporarily stored therein. Each time the manual pressing shaft is pressed downwards, the air control valve is activated to rotate a one-fifth revolution. When the manual pressing shaft is pressed five times continuously, that is, the air control valve rotates a complete revolution, the air temporarily stored within the air storage tank will be released and breathed into the patient's mouth via the mouth-nose breather. Such an action must be repeated continuously until the patient is revived.
