Portable transcutaneous electrical nerve stimulation system and method thereof

Abstract

The present invention relates to a portable transcutaneous electrical nerve stimulation system and a method thereof. The portable transcutaneous electrical nerve stimulation system comprises a power control unit, a micro-control unit, a digital analog converter, a feed circuit unit, a working waveform driver, a monitoring circuit unit, a power amplifier and an output circuit unit, wherein the micro-control unit outputs a preset electric stimulation signal via the working waveform driver, and the electric stimulation signal stimulates the skin electrically after passing the power amplifier and via the output circuit unit; the monitoring circuit unit real-timely monitors an output current of the output circuit unit, a current signal is converted by the digital analog converter and then is sent to the micro-control unit to be compared with a preset electric stimulation parameter, and the micro-control unit corrects the electric stimulation signal; the power control unit and the feed circuit unit control the electric energy needed by the power amplifier via the micro-control unit, and turn off the electric energy at the working clearance of the electric stimulation signal. The portable transcutaneous electrical nerve stimulation system and the method thereof are reasonable in design, are suitable for the habitus of the people of our country, and provide important parameter support for preventing the lower limb deep venous thrombosis via the transcutaneous electrical nerve stimulation and a new prevention approach.

Description

technical field [0001] The invention relates to a technology in the field of medical equipment, in particular to a portable transcutaneous electrical nerve stimulation system and a method thereof. Background technique [0002] Overseas studies on the prevention of deep vein thrombosis by electrical stimulation started earlier, but only in recent years have there been more developments, mainly including the short-term and long-term effects of electrical stimulation on different parts of the lower extremity on the hemodynamics of deep veins of the lower extremities, and its Compared with the effects of several other physical prevention methods, etc. The methods of electrical stimulation mainly include neuromuscular electrical stimulation (Neuromuscular electrical stimulation) and transcutaneous electrical nerve stimulation (Transcutaneous electrical nerve stimulation). The former uses electric current to stimulate the movement point of the target muscle or muscle group, thereb...

AI Technical Summary

Problems solved by technology

In addition, the electrical stimulation devices used in these studies were not specifically designed for deep vein thrombosis prevention, and while some stimulators are powerful, they are expensive and non-portable, making them unsuitable for everyday home use

[0004] There are no domestic electrical stimulation products dedicated to the prevention of deep vein thrombosis, and rela...
