Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the scope expressed in the embodiments.

[0029] like figure 1 As shown, the electric external counterpulsation device of the present invention includes an electrocardiographic detection device, a counterpulsation device control host, and a counterpulsation device servo system. The pulse device servo system is composed of a servo motor drive device, a servo motor and a mechanical transmission mechanism. The central electrical detection device detects the movement signal of the heart. Its function and equipment selection are the same as the traditional detection; The ECG signal detected by the device is processed, the second heart sound is recognized and the command signal for the action of the counterpulsation device is issued. The servo motor drive device in the servo system of the counterpulsation devi...

Abstract

The invention discloses an electric external counterpulsation device, consisting of an electrocardiograph wave detector, a control host of the counterpulsation device and a servo system of the counterpulsation device; the electrocardiograph wave detector, the control host of the counterpulsation device and the servo system of the counterpulsation device are sequentially connected; wherein the electrocardiograph wave detector is used for detecting motion signals of the heart, the control host of the counterpulsation device processes the electrocardiosignals detected by the electrocardiograph wave detector and sends out the command signals for the action of the counterpulsation device, and the servo system of the counterpulsation device implements the command sent out by the control host of the counterpulsation device to realize external counterpulsation. The power source of the invention to realize counterpulsation motion is the electric external counterpulsation, that is to say, the mechanical energy for counterpulsation is directly supplied by a motor rather than the way that the motor drives an air compressor or an oil hydraulic press to transform electrical energy into fluid pressure. Compared with the prior art, the electric external counterpulsation device of the invention has the advantages of compact structure, small volume, little noise, realizable fine control and being suitable for household use, etc.

Description

technical field [0001] The invention relates to an external counterpulsation device, in particular to a non-pneumatic and hydraulic counterpulsation power source. Background technique [0002] At present, external counterpulsation devices at home and abroad all use fluid as the power source, most of them use compressed air as the power source for counterpulsation, and some use fluid (hydraulic pressure) as the power source. For example, the external counterpulsation devices disclosed in Chinese patents 85200090.5, 87200288.8, 88203328.X and 91103893.0 are composed of compressors (air compressors or hydraulic presses), gas storage tanks or oil storage tanks, electromagnetic valve groups and various pipeline parts. , airbags and other components. The principle of these external counterpulsation devices is that the air compressor and the air storage tank generate a high pressure source, and then by identifying the heart sound, when the second heart sound (that is, the beginnin...
