Implantable heart assist blood supply device based on wireless power transmission

Abstract

The invention provides an implantable heart assisted blood supply device based on wireless power transfer. The device comprises an external power source, an outside wireless power supply transmissionmodule, an inside wireless power supply transmission module and an EAP, the outside wireless power supply transmission module comprises a high-frequency inverter and a transmitting coil, the inside wireless power supply transmission module comprises a receiving coil, a high-frequency rectifier bridge and a filter circuit, the external power source is connected with the high-frequency inverter which is connected with the transmitting coil, the transmitting coil and the receiving coil are in inductive coupling, the receiving coil is connected with the high-frequency rectifier bridge which is connected with the filter circuit, the filter circuit is connected with the EAP which is attached on the outer side of a vascular wall, the EAP is of a structure with upper, middle and lower layers, andthe upper layer and the lower layer are electrified. An EAP loaded wireless power supply mode is adopted for assistant blood supply, so that burden of a patient is relieved, and risks of skin infection and secondary operation which are prone to being caused by wired connection are reduced.

Description

technical field [0001] The invention belongs to the technical field of cardiac assisted blood supply, in particular to an implantable cardiac assisted blood supply device based on 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] The volume of the motor pump is large, which is not conducive to the installation of the surgeon. At the same time, it is heavy, which is also a burden to the patient. The main problem is that the power supply required by the motor pump needs to be externally connected to the external power cord through subcutaneous surgery, so that the long-term The exposed wound can cause bacterial or viral infection, which seriously threatens the life and health of the patient and increa...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention aims to propose an implantable cardiac auxiliary blood supply device based on wireless energy transmission, which solves the problems that the traditional human body auxiliary blood supply device is large in size, and the external power supply is easy to cause bacterial infection and thus threaten the health of the patient. Reduce the burden on patients by eliminating the trouble and risk of secondary surgery
