Electronic frostbite treatment device circuit diagram

The electronic frostbite treatment instrument special integrated circuit SL9711 constitutes an oscillation circuit, a power amplifier circuit and a controller, which generates 100Hz and 3Hz sine waves. After being boosted by a transformer, the potentiometer adjusts the current in the electroacupuncture circuit. Since a diode is added to the output , the current waveform flowing through the human body is a pulsating current. When acting on the human body, the motor nerves are stimulated and cause muscle tremors. After tens of seconds, the tingling sensation disappears, the sensory and motor nerves begin to enter a state of inhibition, the pain threshold rises and exhibits an analgesic effect. Because the pulsating current inhibits the AC nerves and causes trace denaturation and decomposition of the proteins through which the current passes, it is converted into vasoactive peptides, etc. Substance, therefore after the pulsating current stops, it still has the effect of improving local blood circulation and later analgesic.
