Human body auxiliary blood supplying device with wireless power transmission

Abstract

The invention provides a human body auxiliary blood supplying device with wireless power transmission. According to the blood supplying device, an external power supply, a bus capacitor, an inverter and an energy transmitting coil are successively connected, a main controller is connected with the inverter, a repeating coil and the energy transmitting coil are in the same plane, and the repeatingcoil sleeves the outer portion of the energy transmitting coil; a receiving coil, a high-voltage rectifier bridge, a maintaining capacitor and electroactivity polymer thin film are successively connected, the receiving coil receives energy transferred by nuclear resonance which is transmitted by a wireless power transmitting device, the energy is converted into electric waves through the high voltage rectifier bridge, and after filtering conducted by the maintaining capacitor, the electroactivity polymer thin film is controlled to be shrunken. The problems that the traditional human body auxiliary blood supplying device is large in size, and a power supply arranged at the outside can easily cause bacterial infection, therefore health of patients can be threatened are solved. EAP thin filmclosely sleeves the vascular wall outside the ventricle and is small in size, a wireless power receiving device driving the EAP thin film is built in a human body, and the problem that the power supply arranged at the outside causes bacterial infection is avoided.

Description

technical field [0001] The invention relates to a human body auxiliary blood supply device, in particular to a human body auxiliary blood supply device for wireless energy transmission, 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 for t...
