Abstract

The invention relates to an electromagnetic induction energy-supply device used for implantation-type medical equipments, which comprises a transmitting circuit arranged in vitro and a receiving circuit implanted in vivo; the receiving circuit in vivo comprises a receiving coil composed by the spiral inductance coil with board non-core plane, a rectifier circuit and a filter circuit which are connected with the receiving coil sequentially; the transmitting circuit in vitro comprises a transmitting coil composed by the spiral inductor with board non-core plane and a launching driving circuit which is connected with the input end of the transmitting coil and comprises a power circuit, an oscillation circuit and a power amplification circuit. The device adopts the electromagnetic induction principle to transmit the transcutaneous energy from an external control module, thus realizing the energy-supply to the implantation-type medical equipments, and is applied in the implantation-type medical equipments.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to an energy supply device for percutaneous energy transmission of implantable medical equipment. Background technique [0002] There are many types of implantable medical devices, and their applications are also very wide. Common ones include cochlear implants, cardiac pacemakers, deep brain stimulators, artificial sphincters, peripheral nerve stimulators, and muscle stimulators. [0003] The main determinant of the service life of various implantable medical devices is the capacity of the battery. Traditional implantable medical devices are powered by lithium batteries with high energy density. In order to prolong the service life of implantable medical devices, it is necessary to reduce the power consumption of the implanted device circuits as much as possible while increasing the battery capacity, which makes The weight and volume of batteries in implanted medical d...
