Drive apparatus for external pump

Abstract

The present invention relates to one kind of external back beating apparatus comprising solenoid valve, cylinder and pushing board. The solenoid valve controls air with relatively high pressure to drive the piston inside the cylinder for bi-directional motion, and the pushing board acted with the piston applies pressure to limbs and trunk to promote blood circulation. The cylinder is driven with the fluid from the solenoid valve in two directions to produce excellent blood circulation promoting effect. The cylinder is driven with air source of high pressure, and this results in low air consumption, small volume of the air source, valve and pipeline, and small size of the back beating apparatus. The present invention may be used in back beating treatment, salvage in sick bed, health care and rehabilitation.

Description

technical field [0001] The invention relates to a medical device, in particular to an external counterpulsation driving device which presses a push plate on a human body through a cylinder to promote blood circulation. Background technique [0002] External counterpulsation is a method for the treatment of cardiovascular and cerebrovascular diseases that has emerged in the past two decades. This method cooperates with the heartbeat to rhythmically pressurize the patient's limbs, driving the blood in the patient's body to accelerate circulation, so as to achieve the purpose of treatment. [0003] Since the advent of external counterpulsation, the driving device that exerts pressure on the human body usually adopts the method of inflating and deflating the low-pressure airbag. 2 ) drive, so there is an obvious consequence that the volume of the air pump is large, and the size of the connecting pipe is difficult to reduce, and because the pressure of the air source used is low,...

Problems solved by technology

[0003] Since the advent of external counterpulsation, the driving device that exerts pressure on the human body usually adopts the method of inflating and deflating the low-pressure airbag. 2 ) drive, so there is an obvious consequence that the volume of the air pump is large, and the size of the connecting pipe is difficult to reduce, and because the pressure of the air source used is low, the pressure rise rate and exhaust speed in the air bag cannot be fast when inflated, which affects the curative effect of counterpulsation

Slow airbag exhaust will also cause incomplete exhaust, which makes counterpulsation patients feel uncomfortable
