Artificial cochlea

Abstract

The invention discloses an artificial cochlea to reduce potential hazards of products to a human body. The external machine part of the artificial cochlea comprise a speech processor, an external magnet and a transmission coil, wherein the speech processor processes sound wave signals and generates coded signals; the external magnet attracts an internal magnet which is arranged in an implant device; the transmission coil comprises more than one external coil; the external coils are wound around the external magnet respectively and are grounded; the external coils are exclusively and concentrically connected with the same number of internal coils in the implant device; and each external coil corresponds to an independent speech frequency range of the speech processor, receives the output coded signals of each speech frequency range of the speech processor and correspondingly transmits the coded signals of each speech frequency range to the identical numbers of internal coils in the implant device one by one. The artificial cochlea reduces the potential hazards to the human body, improves the product safety and has high convenience and usability.

Description

technical field [0001] The invention relates to an electronic product, in particular to a cochlear implant. Background technique [0002] figure 1 It is a structural schematic diagram of a cochlear implant in the prior art. Such as figure 1 As shown, the cochlear implant mainly includes an external machine part 100 and an implant device 200 implanted in the human brain. Encoding: After obtaining the encoded signal, it passes through the transmitting coil 130 and transmits it through the skin to the receiving coil 140 of the implant device 200, and then the decoding circuit 150 of the implant device 200 performs decoding to obtain a decoded signal, and transmits the decoded signal to the electrodes of the cochlear implant The array 160 stimulates the user's auditory nerves so that the user can recover hearing. Wherein, the receiving coil 140, the decoding circuit 150 and the electrode array 160 are usually wrapped and sealed together by silica gel. Wherein, the above-men...

AI Technical Summary

Problems solved by technology

[0003] In the existing cochlear implants, although the decoding circuit in the implanted device implanted in the human body is sealed, due to the complexity of the circuit and the components in it are not compatible with human tissue, it is inevitable to soak in human body fluid for a long time. Seal leakage leads to serious consequences such as cochlear implant failure and harmful substances entering the human brain and causing infection. These serious consequences are likely to bring more serious sequelae

Therefore, the existing cochlear implants actually have greater potential harm

[0004] In addition, the existing cochlear implant has a complex structure, resulting in high cost, complicated process, and high difficulty in manufacturing

Moreover, due to its large size, it needs to cause a large trauma to the important part of the human body-the head when implanted in the human body, and it is also difficult to fix it inside the human body.
