Simple small electrotherapy devices

Transistor VT1 and transformer T, capacitor C, resistor R1 and potentiometer RP1 intermittent form a frequency adjustable oscillator. Intermittent pulse voltage step-up by the transformer turns ratio, in a sense secondary winding up to 50 ~ 60V birth pulse. After the electrical pulse divider potentiometer RP2 point lead into the body. Adjustment potentiometer can be more appropriate pulse intensity to stimulate acupuncture points. Silver needles to replace the electrical pulses, to the effect of pain treatment.

The characteristics of electrotherapy devices to automatically adsorbed on the electrode body. By glucose injection can be made stopper. Diameter with a knife at one end plug removed. A small cylindrical rubber plug in the center, wearing a small hole with an awl. The bulk of the aluminum rivet head on the plug the small end of the first piercing the stopper head. Put prior to weld the welding wire piece, and then rivet tight. When the points are not easily adsorbed rubber absorber, you can use as electrode E fish folder. Do use the rubber electrode adsorber, then caught alligator clip electrodes connected to lug.

Before treatment, full of light absorption by medical cotton salt water, squeezed in the first rubber plug. Find a good point, points will be opening snapping the skin, two fingers from the side of symmetric direction of a squeeze, let go after the rubber plug automatic suction on the skin. Salt water from the conductivity in this role only. Course of treatment, one can not help electrode. So not only can give on others, but also their treatment.

According to their different situations, you can choose the electric pulse repetition frequency (tone RP1) and strength (adjusted RP2). Then we can see there is a flashing orange neon bulb shining. Generally choose to see the flashing red but not so brilliant even as a standard frequency as well. Regulate the output amplitude, so that those who are needle feeling pain, but also appropriate for the patient can bear.

Electrotherapy device shown in Figure is not only as a source of electrical pulses of acupuncture and cupping can also play a role in type of electric excitement.
