Abstract

The invention discloses a wireless rechargeable-type artificial cochlea, which comprises an implant and an extracorporeal machine, wherein the wireless rechargeable-type artificial cochlea is characterized in that: a micro-battery and a charging circuit are arranged inside the implant; a wireless signal receiving and sending antenna and a wireless charging transmitter coil are arranged on the extracorporeal machine; the extracorporeal machine carries out speech processing on a voice signal after amplifying the collected voice signal, and then performs signal and electric energy transmission with the implant through the wireless signal receiving and sending antenna and the wireless charging transmitter coil; the implant outputs the voice signal from the received voice signal and the electric energy in a current manner out of an exciting electrode via a decoding stimulator and charges the micro-battery at the same time. Compared with the prior art, the wireless rechargeable-type artificial cochlea disclosed by the invention is simple in structure, convenient in use and good in beautiful degree; an ear machine is removed, so that the daily activity of a sufferer is not affected. Psychological health of the sufferer is further facilitated, and the reliability and the security of the artificial cochlea are improved by various work modes.

Description

technical field [0001] The invention relates to the technical field of bionic medical electronics, in particular to a wireless rechargeable cochlear implant. Background technique [0002] The cochlear implant is an electronic device with a high content of bionics science and technology at present, and it is mainly used to help patients with severe or extremely severe deafness who wear hearing aids that are not effective or effective at all. The cochlear implant converts sound waves into weak current signals and transmits the current signals to the inner ear (cochlea). The multi-channel electrodes implanted in the cochlea stimulate the auditory nerve fibers in the cochlea to generate nerve impulses and transmit the nerve impulses to the brain. Thus forming the sense of hearing. [0003] The cochlear implant consists of an implanted device in the body and a speech processor worn outside the body. The external device includes a microphone, an amplifier circuit, a speech signal...
