A multi-receiving terminal wireless power transmission auxiliary blood supply device with a relay coil

Abstract

The invention provides a multi-receiving-terminal wireless electric energy transmission device used for assisting blood supply and provided with a repeating coil. An external power supply control system, a bus capacitor, an inverter and an energy transmission coil of the device for assisting blood supply are connected in sequence, the repeating coil and the energy transmission coil are located inthe same plane, and the repeating coil is nested outside the energy transmission coil. Receiving coils, a high-voltage rectifier bridge, a DC-DC conversion device, a maintenance capacitor and an electroactive thin polymer film are connected in sequence, n receiving coils receive energy transferred by the wireless electric energy transmission device through nuclear resonance, the energy is converted into electric waves through the high-voltage rectifier bridge, and the electric waves are transmitted to the DC-DC conversion device, are filtered by the maintenance capacitor and then are suppliedfor the electroactive thin polymer film. The problem is solved that a traditional human body blood supply assisting device is large in size, external arrangement of a power supply causes bacterial infection and accordingly the body health of a patient is threatened. The multi-receiving-terminal power supply mode of the device makes multiple in-vivo implantable EAP thin films work simultaneously, and blood supply of blood vessels at multiple parts can be assisted simultaneously.

Description

technical field [0001] The invention relates to a human body auxiliary blood supply device, in particular to a wireless energy transmission auxiliary blood supply device with a relay coil, belonging to the field of auxiliary blood supply devices. Background technique [0002] Between the four atria (chambers) of the heart are valves that play a vital role in keeping blood circulating in one direction by opening or closing the valves, preventing blood from flowing back into the ventricle it just left. For patients with severe organ failure, the various structures of the heart can no longer function normally, and artificial assisting devices need to be implanted. 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. However, this traditional auxiliary blood supply pump fo...
