Description
technical field [0001] The invention relates to a wireless power supply annular auxiliary blood supply device, which belongs to the field of wireless energy transmission. Background technique [0002] In the treatment of heart failure, the traditional method uses a human body auxiliary blood supply pump, that is, a motor device is installed in the main blood vessel of the heart to assist and replace the heart pumping function to supply blood to human organs. [0003] However, due to the large volume of the motor pump, it is not conducive to the installation of the surgeon. At the same time, the weight is heavy, which is also a burden to the patient. The main problem is that it needs to go through subcutaneous surgery, connect the power cord externally, and externally connect the power supply required by the motor pump. Long-term exposure of the wound can cause bacterial or viral infection, which seriously threatens the life and health of the patient. Contents of the invent...
