Title:

DRIVING DEVICE FOR EXTERNAL COUNTERPULSATION

Document Type and Number:

WIPO Patent Application WO/2005/009321

Kind Code:

A1

Abstract:

The present invention relates to a driving device for external counterpulsation, which includes solenoid valves (1), air cylinders (2) and pusher plates (3). The solenoid valves (1) control higher voltage driving the two way motion of pistons (21) in the fir cylinders (2), the pistons (21) act on the pusher plates (3), and the pusher plates (3) bear down on the extremities (5), so it can drive the blood circulation. The air cylinders (2) are driven in two way by liquid brought from the solenoid valves (1), they act quickly, so it can bring good effect of driving the blood circulation. Since the air cylinders (2) are driven by an air source with higher pressure, the air expended is less. The fact that the size of the device of air source for counterpulsation, the valve, the pipeline and so on reducing accordingly, makes the size of the device for counterpulsation reduced. So the device is portable, and it can be used in both the treat of counterpulsation, rescue by the bedside, and improving one’s health, health care, healing, or in the family.
