Implantable wireless electric energy transmission device

Abstract

The invention discloses an implantable wireless electric energy transmission device. The device comprises a transmitting circuit, a transmitting coil, a receiving coil and a load circuit; the transmitting circuit is mainly composed of a power supply module, a high-frequency inversion module and an RLC electric energy transmitting module; the load circuit is mainly composed of an RLC electric energy receiving module, a high-frequency rectifying module, a DC-DC voltage stabilizing module and a battery charging module; the transmitting circuit converts alternating current into direct current through rectification, converts the direct current into alternating current through high frequency inversion, and finally applies electric signals onto the RLC transmitting module so as to convert electric field energy into magnetic field energy; the magnetic field energy can be transmitted from the transmitting coil to the receiving coil, and is finally transferred to the load circuit; and the load circuit converts the magnetic field energy transmitted from the receiving coil into electric field current signals through the RLC electric energy receiving module, obtains a direct-current signal through high-frequency rectification, and can obtain stable direct-current current for charging an implanted device through the DC-DC voltage stabilizing circuit.

Description

technical field [0001] The invention belongs to the technical field of medical implant power transmission, in particular to an implantable wireless power transmission device. Background technique [0002] With the continuous development and progress of medical technology in our country, the application of implantable devices is becoming more and more extensive, but as we all know, the biggest obstacle to its development is the problem of difficult charging. General implantable devices mainly use a built-in battery as a power source. This battery usually has a certain working life, but once the energy is nearly exhausted, the battery needs to be replaced. However, there is no definite judgment on when the power will be exhausted. It even needs to be checked several times before the end of life, so as to avoid a series of serious consequences caused by the battery power depletion, and multiple unscheduled checks will undoubtedly cause a lot of inconvenience.

General implantable devices mainly use a built-in battery as a power source. This battery usually has a certain working life, but once the energy is close to exhaustion, the battery needs to be replaced. However, there is no definite judgment on when the battery will be exhausted.

It even needs to be checked several times before the end of life, so as to avoid a series of serious consequences caused by the battery running out, and multiple irregular checks will undoubtedly cause a lot of inconvenience
