A wireless charging device and method for a cochlear implant speech processor

Abstract

The invention discloses a wireless charging device and a wireless charging method for an artificial cochlea speed processor. The wireless charging device comprises a charger and a speed processor wireless charging portion, wherein the charger comprises a charging groove, a charging control microprocessor, a radio frequency transmission driving module, a transmitting coil, a proximity sensing module, a data back-transmission receiving coil and a radio frequency data back-transmission and amplification circuit; and the speed processor wireless charging portion comprises a charge receiving coil, a detection and rectification module, a voltage stabilization module, a current detection module, a charge control chip, a rechargeable battery, a temperature sensor, an ADC module and a load modulation module. According to the invention, a speed processor and a battery compartment are designed into an integral whole, a problem of reliability brought about by mechanical wear of a connector does not exist, and charging is also enabled to be simpler and more convenient, thereby being easy to seal and maintain, prolonging the service life, and being suitable for a new generation of fully-sealed waterproof artificial cochlea speed processors.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a wireless charging device and method for a cochlear implant speech processor. Background technique [0002] At present, the cochlear implant is a multi-channel cochlear implant, which consists of an implanted device in the body and a speech processor worn outside the body. The implant includes a wireless receiving coil, a decoding chip and stimulating electrodes, and the external device includes a microphone, an amplifier circuit, a voice signal Processing and coding circuit and radio frequency transmission circuit, according to the principle of human ear position coding, the in vitro machine first encodes and modulates the voice signal, and sends it to the implant through radio frequency. After the implant receives the signal, its decoding chip performs demodulation and decoding , and then stimulate N implanted electrodes to stimulate the auditory nerve to produce hearing. Since...
