Electronic performance testing device for artificial cochlea implant

Abstract

The invention discloses an electronic performance testing desk for an artificial cochlea implant. The testing device comprises a housing; a panel is arranged on the housing; a circuit board is arranged in the testing desk; an electrode contact pole testing template is arranged on the circuit board; the surface of the electrode contact pole testing template contains an electrode contact pole made of a metal material, and the back surface of the electrode contact pole testing template contains an insulation layer; the electrode contact pole testing template is connected with one end of an electrode terminal by an electrode lead; and the other end of the electrode terminal is arranged on the panel of the housing. Adoption of the electronic performance testing desk disclosed by the invention not only can be convenient to test a main electronic performance testing index of the artificial cochlea implant, but also greatly improves testing efficiency and accuracy and enables a main electronicperformance testing technology of the artificial cochlea implant to be promoted substantially.

Description

technical field [0001] The invention relates to an electronic testing technology for an artificial cochlear implant, in particular to an electronic testing device for testing electronic performance indicators of an artificial cochlear implant. Background technique [0002] A cochlear implant is an electronic device that converts sound into an electrical signal in a certain coded form by an external speech processor, and directly stimulates the auditory nerve to hear the sound through the electrode system implanted in the body, improving and rebuilding the auditory function of the hearing-impaired patient. [0003] The main electronic performance test indicators of cochlear implant technology include: output signal characteristics, output signal amplitude and pulse width, impedance measurement accuracy, inter-electrode impedance, impulse response range, etc. [0004] Because the electrodes of the cochlear implant are arranged in a tight array, generally 20 to 24 electrodes ar...

AI Technical Summary

Problems solved by technology

[0004] Because the electrodes of the cochlear implant are arranged in a tight array, generally 20 to 24 electrodes are distributed within the range of 15 to 25 mm, and the average electrode spacing is less than 0.4 mm. However, such a dense electrode distribution prevents the inspector from directly checking the electrodes in the electrode array. Single electrode for testing

Even if the test is carried out, it will make it difficult for the inspectors to test and the test results will be inaccurate
