Traditional Chinese Simple Small Electrotherapy Apparatus (Workshop Practice) — Circuit, Wiring & Debug Guide
In short: Traditional Chinese Simple Small Electrotherapy Apparatus (Workshop Practice) — Circuit, Wiring & Debug Guide. This entry documents a circuit & prototype taken from Chinese practical-technology literature, written for small-scale makers and home producers. The text below is the full English translation of the original Chinese workshop notes, covering materials and quantities, the step-by-step sequence, and the practical cautions recorded in the source. Roughly 2560 words of English technical text, translated and preserved without editing. It is intended for experimental and reference use, not for regulated or commercial certification.
Simple small electrotherapy deviceThe electrotherapeutic device shown in Figure 45 can not only be used as a pulse source for electroacupuncture, but also play a cupping-style electrical stimulation effect.Transistor VT1, transformer T, capacitor C, resistor R1 and potentiometer RP1 form a frequency-adjustable intermittent oscillator. The intermittent pulse voltage is boosted by the transformer ratio, and pulses up to 50-60V are induced in the secondary winding. The electrical pulse is led to human acupoints through the potentiometer RP2 partial pressure. Adjusting the potentiometer can obtain a more suitable pulse intensity and stimulate acupuncture points. Electric pulses are used instead of silver needles to achieve the effect of treating pain. alt="74.jpg (26087 bytes)"> …
