Problems solved by technology

[0004] At present, the main problem of the external ventricle compression pump is that it can only perform auxiliary compressions according to the preset compression frequency and compression amplitude, and cannot collect the displacement amplitude and frequency of heart expansion and contraction during the compression process. Beat frequency mismatch, resulting in arrhythmia, heart fibrillation and other clinical problems, endangering the life of the patient
Although there is currently a detection device for cardiac beating, it requires a separate device and equipment, and cannot be integrated with the existing ventricular pump

Embodiment 1

[0043] Such as figure 1 As shown, the present embodiment provides an extra-ventricular compression assisting device integrating a displacement sensor and a pressure sensor, including: a displacement acquisition device, a pressure acquisition device, a controller, and an extra-ventricular compression device; the displacement acquisition device includes an elastic belt 4 and The displacement sensor is composed of a plurality of elastic belts 4 arranged in the circumferential direction and vertically to form a mesh structure, the displacement sensor is arranged on the elastic belt 4, and the displacement sensor is connected with the controller 5; the pressure acquisition device is arranged in the center The outdoor pressing device is connected with the controller; the controller is connected with the outdoor pressing device, and the outdoor pressing device is driven to act by the controller.

[0044] Specifically, such as figure 2 As shown, the displacement acquisition device h...

Embodiment 2

[0063] Such as Figure 5 As shown, the present embodiment provides a working method of the above-mentioned extra-ventricular compression assisting device, which is as follows:

[0064] The displacement sensor is connected to the controller, and the collected displacement amplitude and frequency signals of the heart beat are transmitted to the controller through the signal line;

[0065] The pressure sensor is connected to the controller, and the collected pressure signal is transmitted to the controller, and the pressure signal reflects the force of the pressing device on the heart;

[0066] At the same time, it controls and receives external setting signals. The external setting signals are signals adjusted by the medical staff to the ventricular assist device according to the patient's condition. It can be pre-set, or can be adjusted and input in real time according to the patient's condition;

[0067] According to the displacement amplitude and frequency of the left and ri...

Abstract

The invention discloses an external cardiac compression auxiliary device and a working method thereof. The external cardiac compression auxiliary device comprises a displacement quick device, a pressure quick device, a controller and an external cardiac compression device, the displacement quick device comprises elastic belts and a displacement sensor, a plurality of elastic belts arranged in the circumferential direction and the vertical direction form a net structure, and the displacement sensor is arranged on the elastic belts and connected with the controller; the pressure quick device is arranged on the heart chamber outer pressing device and is connected with the controller; the controller is connected with the heart chamber outer pressing device and drives the heart chamber outer pressing device to act. Cardiac impulse information during pressing is collected in real time through the displacement collecting device, acting force between the pressing device and the heart is detected in real time through the pressure sensor, and the controller receives three input signals of a displacement sensor signal, a pressure sensor signal and an external setting signal so as to drive the external cardiac compression device to act.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an extra-ventricular compression assisting device and a working method thereof. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Ventricular assist device is a mechanical device made of artificial materials, which can temporarily or permanently replace the pumping function of the heart, reduce the load on the heart, and help the heart achieve blood circulation. It is an important medical method for treating heart failure and prolonging the life of patients. According to the working mode, ventricular assist devices can be divided into two types: blood-contacting and non-blood-contacting. The blood-contact type is a heart pump, which uses the principle of the pump to connect with the human circulatory system to realize part or all of the ...
