Embodiment Construction

[0017] refer to Figure 1 to Figure 3 , a new type of external counterpulsator, including calf airbags, thigh airbags and buttock airbags, the above-mentioned airbags are connected to an air storage tank and an air compressor through a solenoid valve, and the air storage tank is connected to an electric pressure regulating valve and a silencer. It communicates with the negative pressure tank, and the negative pressure tank communicates with the air compressor. When a person's blood pressure becomes high, the electric pressure regulating valve will open, and the gas in the air storage tank will be discharged to the outside through the muffler, thereby reducing the air pressure of the calf airbag, thigh airbag and buttock airbag, so as to ensure that the blood circulation of the human body is maintained at a certain level. Run in a comfort zone. On the contrary, when the blood pressure of the human body becomes low, the electric pressure regulating valve will close the valve, l...

Abstract

The invention discloses a novel external pressure circulatory assist. The external pressure circulatory assist comprises shank airbags, thigh airbags and hip airbags. The airbags are communicated withan air storage tank and an air compressor through solenoid valves, the air storage tank is communicated with an electric pressure regulating valve and a muffler, the airbags are further communicatedwith a negative pressure tank through solenoid valves, and the negative pressure tank is communicated with the air compressor. The external pressure circulatory assist has the advantages of being highin stability and long in service life.

Description

technical field [0001] The invention relates to a counterpulsator, in particular to a novel external counterpulsator. Background technique [0002] Existing external counterpulsators include calf airbags, thigh airbags and buttock airbags, and the airbags communicate with an air storage tank and an air compressor through respective electromagnetic valves. When inflating, the calf air cells are inflated first, then the thigh air cells, and finally the hip air cells; when deflating, the order is reversed. Thereby promoting blood circulation in the body to achieve the effect of conditioning the body. Since the emotions of the human body are easily affected by the outside world, changes in emotions will affect changes in blood flow and blood pressure in the body. At this time, when using an external counterpulsator to regulate the body, the air pressure of the airbag should also be adjusted in time, otherwise the body will During the conditioning process, there will be an unco...
