Abstract

Изобретение относитс к медицинской технике, а именно к устройствам дл электрической стимул ции импульсными токами низкой частоты нервно-мышечной системы и опорно-двигательного аппарата человека в профилактических и лечебных цел х, а также дл получени тренировочного эффекта. Цель изобретени - повышение комфортности воздействи . В электростимул тор введены счетный триггер 21 и в каждом канале регулируемый источник 13 напр жени , двухтактный коммутатор 16 и оптоэлектрон- ный коммутатор 22 с0 формирователем 23 управл ющих импульсов. 4 ил.The invention relates to medical technology, namely, devices for electrical stimulation by pulsed currents of the low frequency of the neuromuscular system and the human musculoskeletal system for prophylactic and therapeutic purposes, as well as for obtaining a training effect. The purpose of the invention is to increase the comfort of exposure. A counting trigger 21 and in each channel an adjustable voltage source 13, a push-pull switch 16 and an optoelectronic switch 22 c0 by a driver of 23 control pulses are introduced into the electrostimulator. 4 il.
