Problems solved by technology

[0002] At present, pulse electrotherapy machines have been widely used, which can excite neuromuscular tissue, promote local blood circulation, relieve pain, calm the central nervous system and reduce inflammation, but the effect is slow and the curative effect is not obvious.
At the same time, due to the improper selection of the waveform of this electrotherapy machine composed of pulse generator, power amplifier, output part and treatment electrodes, when the plates (electrodes) act on the human skin, most of them have a strong acupuncture feeling that makes patients afraid. ; and ...

Method used

Frequency sweep circuit 1 among Fig. 2 mainly is made up of integrated chip IC1, and its model is 4069, and it can carry out frequency modulation to the signal of the narrow pulse generator that pin 14 inserts; Narrow pulse generator is made up of integrated chip IC2 Composition, which is essentially a dual monostable multivibrator, the model is 4528. The signal of pin 6 output by pulse generator IC2 is connected to the base of crystal triode G1, and then connected to adjustable potentiometer W4 via pin 2; pulse shaping circuit 3 is essentially two sets of resistance-capacitance filter circuits connected to the output of IC1, which are controlled by C4 , R5, C3, R4 and C9, R12, C11, R13; the current output pulse waveform is shaped into: the positive high amplitude of the garden head, the negative and negative low amplitude approximate square wave asymmetrical pulse. It has been proved by medical clinical practice that this kind of waveform can quickly open up the meridians, and it also eliminates the strong acupuncture sensation on human skin that is commonly used in pulse therapy instruments, and it has been proved by blood tests that it can achieve iontophoresis of drug ions; the anti-shake circuit In essence, it is a DC voltage generator. When the frequency sweep output signal fluctuates due to poor contact of the output intensity adjustable potentiometer W2 of the instrument, it can keep the output intensity unchanged, and the amplitude can be adjusted by W5 or W6; power amplifier It is composed of BTS130 metal oxide field effect transistor. The signal from the anti-vibration circuit and regulated by W2 is input to its base, amplified without distortion, output from the emitter, and added to the output unit; the output unit is essentially composed of a Composed of an output transformer SB and a resistance-capacitance filter, it can stably increase the output intensity; the display circuit is composed of three level unit integrated chips IC3~IC, which are LM3914 level controllers, and contr...
