Abstract

The invention discloses an artificial cochlear implant chip leakage detection unit and a method, wherein the leakage detection unit includes: a leakage resistance, a detection resistance, a pull-up resistance, a grounding resistance, a switch, a first selector, a second selector, a buffer One end of the leakage resistance is connected to the measured electrode at the output end of the first selector and the second selector, and the other end is grounded or connected to the power supply; one end of the detection resistor is connected to the input end of the first selector, and the other end The switch is connected to the input end of the second selector; the input of the buffer is connected to the detection resistor and the switch, and the output is connected to the ADC unit. The invention can effectively detect the electric leakage of the output electrode of the artificial cochlear implant chip in the chip, and ensure the output safety.

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...
