Abstract

The invention discloses an artificial cochlea implant chip leakage detection unit and an artificial cochlea implant chip leakage detection method. The leakage detection unit comprises a leakage resistor, a detection resistor, a pull-up resistor, a grounding resistor, a switch, a first selector, a second selector, a buffer, and an ADC unit. One end of the leakage resistor is connected with output-end detected electrodes of the first selector and the second selector, and the other end is connected with the ground or a power supply. One end of the detection resistor is connected with the input end of the first selector, and the other end is connected with the input end of the second selector via the switch. The input of the buffer is connected with the detection resistor and the switch, and the output of the buffer is connected with the ADC unit. By adopting the unit and the method of the invention, leakage of the output electrode of an artificial cochlea implant chip can be effectively detected inside the chip, and the safety of output is ensured.

Description

technical field [0001] The invention relates to the field of cochlear implants, in particular to a cochlear implant chip leakage detection unit and method. Background technique [0002] Hair cells in the human cochlea are sensory cells that receive sound. Severe hearing loss occurs when cochlear hair cell damage is severe. A cochlear implant is an electronic device that replaces damaged hair cells and regains sound signals through electrical stimulation of the auditory nerve. It usually consists of an external device and an implantable internal device. Devices outside the body are called speech processors and devices inside the body are called implants. The cochlear implant is surgically buried in the subcutaneous part behind the patient's ear, and the electrode array in the implant is inserted into the scala tympani of the patient's cochlea during the operation to interact with the patient's auditory nerve. [0003] The main function of the speech processor is to pick u...
