Apparatus of cardiopulmonary resuscitator
First Claim
1. A cardiopulmonary resuscitator, comprising:
- a panel for supporting a patient;
a first belt, disposed at a side of the panel, for wrapping around the chest of the patient;
a driving device, connected to the first belt and driven by a pneumatic source to cyclically tighten and loosen the first belt around the chest of the patient comprising;
an air cylinder, disposed on the opposite side of the panel, having a piston rod, and receiving the pneumatic power generated from the pneumatic source to drive the piston rod moving back and forth so as to tighten and loosen the first belt around the chest of the patient;
a second belt connecting to the two ends of the first belt; and
a fastener disposed on the end of the piston rod for catching a part of the second belt;
a controlling module, coupled to the pneumatic source, functioning to control and adjust the pneumatic power generated by the pneumatic source; and
a plurality of rollers contacting the second belt for providing an action force on the second belt so as to increase the tension of the second belt.

Abstract
The present invention discloses an apparatus of cardiopulmonary resuscitator that is operated through a driving mechanism controlled and driven by air power. The driving mechanism functions to actuate a belt adapted to extend around the chest of a patient to generate reciprocating movement of pressing and releasing so as to achieve a purpose of cardiopulmonary resuscitation for recovering heartbeat and breathing of the patent. By means of the disclosure of the present invention, the apparatus of cardiopulmonary resuscitator is capable of being operated in any kinds of occasions without worrying about lack of power electricity. Meanwhile, the driving mechanism can provide higher reliability and lower cost through the mechanism design that is more simplified than the design of electrical control element used in the conventional apparatus.
