A method for testing cochlear electrode performance and output pulse parameters

Abstract

The invention provides a method for detecting the electrode performance of an electrical cochlea and outputting pulse parameters. The method comprises the steps that step 101, a threshold value of pulse sequence signals which are collected in an initial segment is set; step 102, the pulse sequence signals are detected on the basis of the set threshold value, and then an initial point of each pulse is located; step 103, the pulse parameters of the pulses which are output by an electrode of the electrical cochlea are calculated on the basis of the formulas, and the pulse parameters comprise the positive pulse width W+, the negative pulse width W-, an electrode pulse signal positive amplitude value, an electrode pulse signal negative amplitude value and a gap G between biphase stimulating pulses. The performance detecting method is used in quality management assessment before electrical cochlea equipment leaves a factory; according to the method, a pulse parameter detecting module is used for detecting the electrical stimulation pulse information emitted by an electrical cochlea implant and objectively determining the performance of the electrical cochlea, and a result generating module is used for collecting testing information and data and generating analysis evaluation results.

Description

technical field [0001] The invention relates to the field of engineering detection, and proposes a detection method for cochlear electronic stimulation pulse parameters, which is used for evaluating the chip quality of electronic cochlear implants, and specifically relates to a method for detecting the performance of cochlear electronic electrodes and output pulse parameters . Background technique [0002] The mechanism by which people hear sound is that the sound signal is transmitted from the outer ear to the middle ear, the middle ear converts the sound signal into a mechanical vibration signal, and then transmits it to the cochlea in the inner ear, and then the cochlea converts the mechanical vibration signal into an electrical signal, and then passes through Neural pathways transmit to the brain. After research, it is found that the voltage of a complete electrical signal transmitted by the human body's own cochlea is negative in the front and positive in the back. Th...

Problems solved by technology

At present, at home and abroad, the performance of the electrode is basically detected by manually looking at the oscilloscope. The efficiency of this method is very low, and there is a large detection error, which objectively increases the safety hazard of this product.
