Nerve monitoring device based on human body impedance detection

Abstract

A nerve monitoring device based on human body impedance detection is characterized in that the nerve monitoring device comprises a nerve monitoring host (1), an interface box (2), a power line (4) and a monitoring electrode (5), and an impedance detection module (1-1) and an RFID module (1-2) are arranged in the nerve monitoring host (1); the impedance detection module (1-1) comprises a master control CPU module (6), a digital-to-analog conversion module (7), a first analog signal amplification circuit module (8), a channel switching module (9), a signal filtering module (10), a second analog signal amplification module (11) and an analog-to-digital conversion module (12). The electrode contact effectiveness is judged by measuring the impedance value of the monitoring electrode, and the invention has the advantages of accurate reliable and easy operation.

Description

technical field [0001] The invention relates to a medical device, in particular to a nerve monitoring device used in an operation process, in particular to a nerve monitoring device based on human body impedance detection. Background technique [0002] During surgery, nerve monitoring devices are often used to monitor nerves and provide assistance for surgery. The nerve monitoring systems in the prior art are mostly monitoring electrodes used together with nerve monitors. The monitoring electrode is connected with human tissue to form an electrode circuit. When there is myoelectric vibration in the area to be measured, a myoelectric signal will be generated. At this time, the monitoring electrode collects the myoelectric signal and transmits it to the nerve monitor through the electrode line for data processing, and then records EMG and real-time alarm. Helps surgeons locate and identify nerves at risk in the surgical field, thereby protecting nerves from damage during surg...

Problems solved by technology

[0004] The purpose of the present invention is to design a neuromonitoring device for the existing neuromonitoring system. When judging whether the monitoring electrode is effectively in contact with human tissue, through the doctor's experience or the method of naked eye observation, there are large errors and inconvenient use. , by detecting the impedance value between the monitoring electrode and the human tissue, it is judged whether the monitoring electrode is in contact with the human tissue effectively
