As shown in the figure, the electronic frostbite treatment instrument circuit designed by SL9711. The electronic frostbite treatment instrument adopts the integrated circuit SL9711 to form an oscillating circuit, a power amplifying circuit and a controller. The working principle: the integrated circuit generates a sine wave of 100 Hz and 3 Hz, and the potentiometer adjusts the current in the electric needle circuit after being boosted by the transformer. Since a diode is added to the output, the current waveform flowing through the human body is a pulsating current. When applied to the human body, the motor nerve is stimulated to cause muscle fibrillation. After several tens of seconds, the feeling of hemorrhoids disappears, the sensory and motor nerves begin to enter a state of inhibition, and the pain threshold rises to exhibit an analgesic effect. The pulsating current suppresses the alternating nerve and causes a small amount of denaturing and decomposition of the protein through which the current passes, and opens a vasoactive peptide. Substance, therefore, after the pulsating current is stopped, there is still an improvement in local blood circulation and late analgesic effects.
