Embodiment 1

[0026] figure 1 It is a schematic diagram in which the main body of power generation of the self-powered brain pacemaker in Embodiment 1 is a quadrilateral, such as figure 1 As shown, a self-powered brain pacemaker 20 has a power generating portion 200 , a pulse generator 17 and stimulating electrodes 18 . Wherein, the power generating unit 200 includes a power generating body 21 , an output unit, an electric energy storage unit 16 , a fixing unit 22 and an encapsulation layer. The generating body 21 is rectangular, and has a fixing unit 22 on each of the two narrow sides of the rectangle, which is used to fix the generating body 11 on the epicardium in the long axis direction along the systolic direction. When the power generating body is implanted, the heart is exposed through surgery, the power generating body is set along the direction of heart contraction and the fixing part is sutured on the epicardium, so that the power generating body and the epicardium fit together. ...

Embodiment 2

[0032] image 3 It is a schematic diagram of a self-powered brain pacemaker whose power generation part is a triangle in an embodiment of the present invention, as image 3 As shown, the power generation main body 12 of the self-powered brain pacemaker 11 of the present invention is a triangle, and each apex position of the triangle has a fixed unit 13, and the output electrode 14 is connected with the electrode layer (see figure 2 ), the rectification and filtering circuit 15 is connected to the output electrode 14 , and the electric energy storage unit 16 is connected to the rectification and filtering circuit 15 to store the electric energy generated by the power generation unit.

[0033] figure 2 is a cross-sectional view of a self-powered brain pacemaker of an embodiment of the present invention, as figure 2 As shown, the central layer of the power generation body is a piezoelectric material layer 31, and the piezoelectric material layer 31 is composed of a ZnO nanow...

Abstract

The invention provides a self-powered brain pacemaker, which is characterized in that it includes a pulse generator, a stimulating electrode and a power generation unit. The power generation unit includes a power generation body, an output unit, an electric energy storage unit, a fixing unit and an encapsulation layer. Among them, the power generating body is a multi-layer film structure, including a piezoelectric material layer located in the center of the power generating body, and electrode layers located on both sides of the piezoelectric material layer. The power generating body is attached to the surface of the heart to collect heart energy for generating electrical energy. The output unit is connected with the electrode layer, and is used for outputting the current generated by the power generating body to the electric energy storage unit. The energy storage unit is used to store electrical energy and power the pulse generator. The fixing unit is located on the edge of the generating body and is used for fixing the generating body on the epicardium. The encapsulation layer covers the surfaces of the generating body, the output unit, the electric energy storage unit and the fixing unit. The self-powered brain pacemaker of the present invention does not need to replace batteries and can be used for a lifetime.

Description

technical field [0001] The invention relates to a self-powered brain pacemaker, which belongs to the field of medical equipment. Background technique [0002] With the deepening of human understanding of various diseases, more and more diseases can be diagnosed or treated with implanted electronic devices. [0003] Among them, the implanted brain pacemaker can stimulate the nerves that control movement in the brain, inhibit the abnormal signals that cause Parkinson's disease, relieve or even eliminate the symptoms of tremor, stiffness, and slow movement in patients, and restore their original mobility and self-care ability. However, the service life of the battery of the brain pacemaker is 5 to 8 years, and the battery of the brain pacemaker must be replaced by a surgical operation after the power is exhausted. This will not only cause physical pain and psychological fear and anxiety to patients, but also increase the financial burden on patients and their families. Cont...
