DRIVING DEVICE FOR EXTERNAL COUNTERPULSATION

摘要

An external counter-pulsation device in accordance with the present invention includes an electromagnetic valve (1), cylinder (2) and pushing board 3. The electromagnetic valve controls gases of comparatively high pressure to drive the bidirectional movement of the piston 21 which is positioned in the cylinder 2; the piston 21 then acts on the pushing board 3 which exerts pressure to limbs of a human body so as to drive blood circulation. The cylinder 2 is bidirectionally driven by gas flow set by electromagnetic valve (1) and is moved quickly which is benefit to driving the blood circulation well. Since the cylinder 2 applies gas source of higher pressure, the gas consumption is reduced and the gas source assembly, the valve and the gas-supplying pipe of the external counter-pulsation device in accordance with the present invention are accordingly reduced. Therefore, the integrate external counter-pulsation device of the present invention is smaller and lighter and can be used not only for clinical emergency treatment but also for exercise, health care, recovery or for family use. <IMAGE>
