Abstract

The invention belongs to the technical field of external counter pulsation, in particular to an external counter pulsation device based on dual-direction roller screw rods. The external counter pulsation device comprises a machine frame, a driving motor and two dual-direction screw rods, wherein a driving bevel gear is arranged on an output shaft of the driving motor; the two dual-direction screwrods are symmetrically arranged on two sides of the driving motor; driven bevel gears are respectively arranged at the adjacent ends of the two dual-direction screw rods to be meshed with the drivingbevel gear; a first sliding block and a second sliding block which are arranged at intervals are also arranged on each dual-direction screw rod in a sleeving manner; each first sliding block cooperates with right-hand threads formed in the corresponding dual-direction screw rod, and each second sliding block cooperates with left-hand threads formed in the corresponding dual-direction screw rod; and when the dual-direction screw rods are driven by the driving motor to rotate, the first sliding blocks and the second sliding blocks are mutually closed or mutually departed. According to the external counter pulsation device disclosed by the invention, clamping blocks on two sides can be driven by the driving motor to perform simultaneous counter pulsation treatment on the limbs of a patient, and the external counter pulsation device is simple and convenient; and besides, the responding speed of the mechanical transmission manner is higher, and the problem of gas leakage of a gas path modedoes not exist.

Description

technical field [0001] The invention belongs to the technical field of external counterpulsation, in particular to an external counterpulsation device based on a bidirectional roller screw. Background technique [0002] External counterpulsation is a method of non-invasively pressing the lower body outside the body to reduce and eliminate the symptoms of angina pectoris and improve the hypoxic-ischemic state of important organs of the body. It is also a medical device for preventing and treating cardiovascular and cerebrovascular diseases. Generally, external counterpulsation inflates and pressurizes the airbags wrapped in the limbs and buttocks during the diastolic period, driving the blood in the arteries of the limbs back to the aorta, significantly increasing the diastolic pressure, increasing the blood flow to the heart, and reducing the heart rate. Afterload: During the systole period, the air bag is quickly exhausted, the pressure is relieved, the systolic pressure in...
