Balanced single-polar component type multi-channel cochlear implant system with detection feedback function

Abstract

The invention provides a balanced single-polar component type multi-channel cochlear implant system with a detection feedback function, which comprises an external device and an internal device which are connected in a radio frequency (RF) coupling induction way, wherein the radio coupling induction way is realized by a radio proximity coupling and feedback load modulation circuit; the internal device comprises a balanced single-polar component type electrode array, a stimulus control unit, a core control unit, an internal RF coupling induction receiving and feedback output unit and a measurement control unit, wherein the balanced single-polar component type electrode array consists of an active electrode beam array used for stimulating cochlear nerves, and a plurality of common electrodearrays used for feeding measurement current signals back from the internal device to the external device; and the stimulus control unit, the core control unit, the internal RF coupling induction receiving and feedback output unit and the measurement control unit are connected with the balanced single-polar component type electrode array and are integrated on an integrated circuit chip by a binary-coded decimal (BCD) process. Through the technical scheme provided by the invention, the aims of once careful mounting, adaptive adjustment and long-term high-quality use can be fulfilled.

Description

technical field [0001] The invention relates to the fields of electronic information technology and medical equipment, in particular to a cochlear artificial system. Background technique [0002] A cochlear implant is an electronic device that restores or obtains hearing for adults or children with severe, profound or total deafness. This device can convert sound signals into electrical signals to directly stimulate auditory nerve fibers, thereby achieving the purpose of restoring the patient's hearing. At present, the working principle of the cochlear implant system is generally to rely on the external speech processor to complete the digitization of sound and electrical signals, decompose, filter and encode them, and then wirelessly transmit them to the internal circuit, and stimulate the human body in the form of current intensity and cross-phase pulses. cochlear nerve. The external and internal devices of the cochlear implant system communicate and provide energy throug...

Problems solved by technology

[0004] According to cochlear physiological experiments, a cochlear implant with a current generator with a working current of 2mA and a working voltage of more than 10V can be used by a variety of patients. If it cannot reach this range, it can only be used in patients with sensitive auditory nerve responses.

At present, there is no unified specification standard for cochlear implant wireless transmission mode and integrated circuit function characteristics
