Rapid performance evaluation system of multichannel synchronous electrical cochlea equipment

Abstract

The invention relates to a rapid performance evaluation system of multichannel synchronous electrical cochlea equipment. The system comprises a pulse parameter configuration module (1), an electrical cochlea parameter setting module (3), a signal collection module (5), a pulse detection module (7) and an electrode performance result displaying module (8). The pulse parameter configuration module (1) is used for setting pulse parameters, then a list of testing pulse sequences is generated, and the pulse parameters comprise the total pulse width, the positive-phase pulse width, the negative-phase pulse width, the pulse clearance, the pulse amplitude, the stimulation ratio and the pulse number. The electrical cochlea module is used for setting the parameters of detection items of an electrical cochlea according to the set pulse parameters. The signal collection module (5) is used for collecting electric signals emitted by an electrode of the electrical cochlea. The pulse detection module (7) is used for detecting the electrode performance of an electrical cochlea implant based on the collected signals, and can detect parameter information of stimulation pulses.

Description

technical field [0001] The invention relates to the field of engineering detection, and proposes an evaluation system for electric stimulation pulse parameters of multi-channel electronic cochlear, which is used for quality evaluation of electronic cochlear hardware equipment and research on electronic cochlear speech strategies. Background technique [0002] A cochlear implant is a medical device that converts sound signals into electrical signals and needs to be implanted into the brain of deaf patients to replace the function of the cochlea. Since the device is essentially a sound-to-electricity conversion device that discharges directly to the human brain, the duration of the cochlear discharge to the brain, the magnitude of the current, and the amount of charge must be strictly controlled within a safe range. The above parameters directly reflect the electrode performance of the cochlear implant as well as the stability and reliability of the current source and the crys...
