External counterpulsation device with precision control and actions

Abstract

The invention discloses an external counterpulsation device with precise control and actions. The external counterpulsation device consists of a precise dynamical system, a liquid packing and compressing device and a human body related information acquisition system; the dynamical system performs linear actions by matching a ball screw on a servo motor; the liquid packing and compressing device takes water as a medium, receives the power of the ball screw, and quickly transmits pressure to the surface of a human body to achieve the aim of counterpulsation; and the human body related information acquisition system precisely controls the compression and release of the counterpulsation by acquiring human body related information. The external counterpulsation device is characterized by that: 1, the action response is quick and controllable, the precise control and actions are realized, and equipment is not needed to be increased to quickly realize negative pressure; 2, components of equipment are greatly reduced to greatly reduce weight, volume and manufacturing cost; 3, the running noise is greatly reduced; 4, the system has precise and simple structure, stable running and low maintenance cost; and 5, the energy is only consumed when the device performs actions, and the energy is saved by over 50 percent. The innovations create conditions for the external counterpulsation to enter families for health care.

Description

technical field [0001] The invention relates to an extracorporeal anti-pulse device, which does not use the current air pressure as the energy transmission mode, but uses the principle of electric control to drive the liquid for pressure transmission. Background technique [0002] At present, most external counterpulsation devices at home and abroad use compressed air as the power source. For example, the external counterpulsation devices disclosed in Chinese patents 91103893.1, 02225981.3, and 03210740.4 are all counterpulsation devices with complex pneumatic power sources. Its principle and structure are all different. [0003] For the pneumatic counterpulsation device, there are obviously the following unchangeable defects: 1. The volume is large, the equipment has many complicated pipelines, the cost is high, and the maintenance cost is high; 2. The compressor and the valve switch have relatively large noise, so the noise is large ;3. Due to the compressibility of gas,...

[0003] For the pneumatic counterpulsation device, there are obviously the following unchangeable defects: 1. The volume is large, the equipment has many complicated pipelines, the cost is high, and the maintenance cost is high; 2. The compressor and the valve switch have relatively large noise, so the noise is large ;3. Due to the compressibility of gas, the action response is not timely, it is difficult to achieve precise action based on the principle of electrocardiogram, which affects the actual medical effect; 4. Due to the temperature rise of gas compression, it is necessary to Another cooling device is installed (such as open-loop gas consumption, which will consume more energy and lower efficiency); 5. If negative pressure is to be achieved, a set of air extraction equipment must be added to make the system more complicated

Due to the above reasons, it is difficult to popularize anti-boosting in vitro, and it is even more difficult to enter the family for health care purposes.
