Self-adaptive device and method for controlling load of nerve and muscle stimulator

Abstract

The invention relates to a self-adaptive device and method for controlling the load of a nerve and muscle stimulator, in particular to a device and a method for monitoring and outputting the electrode load of a medical nerve and muscle stimulator in real time so as to prevent the load of the nerve and muscle stimulator from being subjected to open circuit and generating a high voltage to cause electric shock to a patient or user when the nerve and muscle stimulator is in use. The device comprises an output spigot, a load sensor, an isolation outputting module, an isolation back-feeding module, a main control chip, a display unit and a sound unit. The main control chip is provided with a data processing module, a display mode generating module and a display outputting module. The isolation outputting module is connected with the data processing module arranged in the main control chip through an electronic circuit board and is also connected with the output spigot through the load sensor. The data processing module arranged in the main control chip is connected with the display outputting module through the display mode generating module. The displaying unit and the sound unit are connected with the display outputting module.

Description

technical field [0001] The present invention relates to a nerve and muscle stimulator load adaptive control device and a control method thereof, which relate to a device and a control method for real-time monitoring of electrode load and control output in a medical nerve and muscle stimulator (hereinafter referred to as stimulator), which are used for Avoid electric shocks to patients or users caused by high voltage generated by open-circuit loads of such instruments during clinical treatment in hospitals. Background technique [0002] In the medical field, various types of stimulators generally use skin electrodes as the current channel in contact with the human body. The output circuit of the stimulator is generally designed with a constant current source, and its characteristic is that the output voltage changes with the change of the load resistance to keep the output current constant. When the stimulator is working, if the electrode load is open for some reason (the lo...

AI Technical Summary

Problems solved by technology

[0003] In actual use, due to poor contact of the electrode output plug, internal breakage due to aging of the electrode connecting wire, poor contact between the electrode sheet and the patient's skin, and the patient's movement causes the electrode sheet to fall off, etc. Load open circuit or sudden increase in resistance often occurs. So this kind of electric shock happens more often
