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.

Claims

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; and

a controlling module, coupled to the pneumatic source, functioning to control and adjust the pneumatic power generated by the pneumatic source.

2. The cardiopulmonary resuscitator according to claim 1, wherein the pneumatic source is selected from a group consisting a high pressure bottle and a inflator, which generates air flow through a compression and inflation movement operated by a action force.

3. The cardiopulmonary resuscitator according to claim 1, wherein the driving device further includes an air cylinder, disposed on the other side of the panel, having a piston rod connecting to two ends of the first belt, 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.

4. The cardiopulmonary resuscitator according to claim 1, wherein the driving device further includes:

an air cylinder, disposed on the other 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.

5. The cardiopulmonary resuscitator according to claim 4, further comprising a plurality of roller contacting the second belt for providing action force on the second belt so as to increase the tension of the second belt.

6. The cardiopulmonary resuscitator according to claim 1 wherein the driving device further comprises:

an air cylinder, disposed on the other side of the panel and coupled to the controlling module, having a piston rod performing a reciprocating motion;

a clamping member, disposed at one end of the piston rod;

a pair of second belts connecting to the two ends of the first belt respectively; and

a pair of holders disposed on the two side of the air cylinder and connected to the pair of second belt respectively.

7. The cardiopulmonary resuscitator according to claim 6 wherein the holder further comprises:

a frame;

a slider, disposed on the frame and connected to the second belt, being capable of sliding along to inner side of the frame; and

a strap having two ends, wherein one end of the strap is connected to the slider, and the other end of the strap is connected to the clamping member.

8. The cardiopulmonary resuscitator according to claim 7, further comprises at least a roller contacting the strap for providing action force on the strap so as to increase the tension of the strap.

9. The cardiopulmonary resuscitator according to claim 1, further comprising a massage pad, made of a rubber material and disposed on side of the first belt toward the chest of the patient.

10. The cardiopulmonary resuscitator according to claim 1, wherein the panel further comprises a handle for carrying.

11. The cardiopulmonary resuscitator according to claim 1, wherein the first belt further comprises a fastener for adjusting the first belt according to the size of chest of the patient.

12. 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 flexible body, disposed on one side of the panel opposite to the side for supporting the patient, functioning to tighten and loosen the first belt for compressing and releasing the chest of the patent through a inflating and deflating motion generated by a pneumatic power; and

a controlling module, connected to a pneumatic source, being capable of adjusting the air flow provided from the pneumatic source to pass in and out the flexible body.

13. The cardiopulmonary resuscitator according to claim 12, wherein the flexible body is a bladder.

14. The cardiopulmonary resuscitator according to claim 12, further comprises a second belt with two ends connecting to two ends of the first belt respectively and contacting with the flexible body.

15. The cardiopulmonary resuscitator according to claim 14, wherein there is a buckle disposed between the first belt and the second belt.

16. The cardiopulmonary resuscitator according to claim 14, further comprises a hook-and-loop fastener disposed between the second belt and the flexible body for attaching the flexible body to the second belt.

17. The cardiopulmonary resuscitator according to claim 12, wherein the pneumatic source is selected from a group consisting a high pressure bottle and a inflator, which generates air through a compression and inflation movement operated by a action force.

18. The cardiopulmonary resuscitator according to claim 12, further comprising a massage pad, made of a rubber material and disposed on side of the first belt toward the chest of the patient.

19. The cardiopulmonary resuscitator according to claim 12, wherein the panel further comprises a handle for carrying.

20. The cardiopulmonary resuscitator according to claim 12, wherein the first belt further comprises a fastener for adjusting the first belt according to the size of chest of the patient.
