technical field [0001] The invention relates to the field of medical equipment, in particular to an electroacupuncture treatment system. Background technique [0002] Traditional electro-acupuncture instruments or other low-frequency physiotherapy equipment adopt fixed power amplifier power supply or series potentiometer power amplifier voltage adjustment, which cannot achieve dynamic fluctuation of signal modulation waveform, and is not regulated by the control system, and the output accuracy is poor. [0003] And during the output process, the output signal amplitude cannot be detected. For some applications that require constant current output, the constant current output cannot be realized without a detection link.

AI Technical Summary

Problems solved by technology

[0002] Traditional electro-acupuncture instruments or other low-frequency physiotherapy equipment use a fixed power amplifier power supply or series potentiometer power amplifier voltage adjustment, which cannot achieve dynamic fluctuations in signal modulation waveforms, and is not regulated by the control system, resulting in poor output accuracy.

[0003] And in the output process, the output signal amplitude cannot be detected. For some applications that require constant current output, constant current output cannot be achieved without a detection link.

[0004] Moreover, the output terminal of the traditional electroacupuncture instrument, that is, the electroacupuncture is directly connected to the human body without isolation. When the system is charged, the charging part is damaged, or the power adapter breaks down, there is a great potential safety hazard.
