Embodiment Construction

[0012] The technical solutions and other beneficial effects of the present invention will be apparent through the detailed description of specific embodiments of the present invention below in conjunction with the accompanying drawings.

[0013] The electric contraction-relaxation mechanism is used to realize the periodic extrusion of the external counterpulsation part of the rehabilitation subject. The stepping motor (9 in the attached drawing) is connected to the take-up shaft (12 in the attached drawing), the rotation angle and speed of the stepping motor are controlled by the remote control module, and the counterpulsation belt is rolled up or loosened by driving the take-up shaft through the rotation of the motor ;The limiting plate is used to limit the counterpulsation site, preventing excessive deviation between the counterpulsation site and the electric contraction-relaxation mechanism; The total circumference of the belt will change periodically. If this part is expos...

Abstract

The invention discloses a rehabilitation type in-vitro counter-pulsation device. The rehabilitation type in-vitro counter-pulsation device is characterized by adopting a novel electric shrinkage-relaxation mechanism, a remote control module and a supporting device, wherein the electric shrinkage-relaxation mechanism comprises a step motor, a rolling shaft, a storage cavity, a guide shaft, a limiting plate and a counter-pulsation belt, and is used for periodic extrusion and relaxation of a counter-pulsation part; the remote control module comprises an input signal interface, a data processing module, a single chip microcomputer, an auxiliary circuit and an output signal interface, and is used for generating a control signal according to the input signal through a counter-pulsation algorithmand outputting the control signal to the electric shrinkage-relaxation mechanism; and the supporting device is used for attitude adjustment of the electric shrinkage-relaxation mechanism. The devicesolves the problems of great size, high noise and poor comfort of a gasbag type counter-pulsation device, realizes distributed type counter-pulsation, can realize remote-control operation, and is suitable for rehabilitation of the ischemic cardio-vascular disease.

Description

【Technical field】 [0001] The invention belongs to the field of auxiliary devices for rehabilitation treatment of cardiovascular diseases, and in particular relates to a distributed remote control external counterpulsation device based on an electric contraction-relaxation mechanism and a method for using the device. 【Background technique】 [0002] As a simple, safe and non-invasive assisted circulation technique, external counterpulsation has been widely used in the adjuvant treatment of various ischemic diseases such as coronary heart disease, angina pectoris, diabetic foot and stroke. As early as the mid-1960s, four hospitals in the United States successively carried out a non-invasive assisted circulation study called "external pulsation", but the effect was not good due to design problems. In the mid-1970s, Zheng Zhensheng and others took the lead in developing a sequential external counterpulsation device in China, using airbags to sequentially pressurize the limbs, whi...
