This invention provides a portable NRD neural response
signal generator, comprising: a shell, a display screen, a
microcontroller control circuit board, side control buttons, and an input / output connector; the display screen shows the
current amplitude of the neural response
signal, the output status of the neural response
signal, and the battery level; the
microcontroller control circuit board acquires the output
voltage signal of the electrodes of the
cochlear implant and outputs a corresponding simulated neural response signal based on the output
voltage signal; the side control buttons are used for power-on operation and selection and confirmation of the neural response signal waveform; the input / output connector is used for
programming, battery charging, and signal output. This invention provides equipment support for verifying the accuracy of measuring neural response signals in cochlear implants, solving the problems of high
signal interference and insufficient amplitude in existing general-purpose
telemetry equipment for measuring neural responses; the waveform shape can be customized, the minimum output waveform amplitude reaches ±50μV, and the waveform is stable and free from external interference.
