Sectioned pressure reduction thrombus prevention instrument and control method thereof

Abstract

The invention discloses a sectioned pressure reduction thrombus prevention instrument which comprises a control module (1), a gas pump (2), a gas cavity (3), a gas release valve (4), a pressure sensor(5), a plurality of gas inlet valves (7) and a plurality of gas bags (8), the control module (1) is used for controlling starting and stopping of the gas pump (2) to control gas pressure of the wholeinstrument and adjusting sectioned pressure parameters, the gas pump (2) is used for generating gas with pressure, the gas cavity (3) is used for containing gas generated by the gas pump (2), the gasrelease valve (4) is used for completing gas release of the gas cavity (3) and the gas bags (8), the pressure sensor (5) is used for measuring pressure of the gas cavity (3) and feeding back pressureto the control module (1), the gas inlet valves (7) is used for controlling the gas of the gas cavity (3) to enter the gas bags (8), and the gas bags (8) are mounted at the body positions for preventing thrombus, so that superficial veins of the mounting positions are pressed and relaxed.

Description

technical field [0001] The invention relates to, in particular, to a segmental decompression thrombosis prevention instrument and a control method thereof. Background technique [0002] Due to long-term bed rest and slow blood circulation in the lower extremities, patients are prone to deep venous thrombosis. In order to prevent the formation of such thrombosis, elastic stockings are commonly used preventive measures at present, which can reduce the incidence of deep venous thrombosis to a certain extent, but the corresponding Since the superficial veins are always in a state of tension and contraction, there is no spontaneous venous return, which easily damages the function of the superficial venous valves. [0003] The electronic sphygmomanometer uses pressure pumps, pressure relief valves, pressure sensors and other means to judge the blood pressure of the human body by pressurizing the upper limbs of the human body and gradually releasing the pressure to detect the press...
