Double-independent mode low-frequency therapy apparatus

Abstract

The invention relates to the field of medical electronic equipment, in particular to a double-independent mode low-frequency therapy apparatus which mainly comprises a power circuit, a control switchcircuit, an intelligent controller CPU, an LCD and a polarity control driving circuit. The low-frequency therapy apparatus is characterized in that the polarity control driving circuit is provided with two channels A and B; the LCD is internally provided with a backlight circuit; the power circuit and the control switch circuit are respectively connected with the CPU, the channels A and B of the polarity control driving circuit and the backlight circuit; the CPU is respectively connected with the LCD, the backlight circuit and the channels A and B of the polarity control driving circuit; and the channels A and B of the polarity control driving circuit can respectively and independently output and has the adjustable intensity. The low-frequency therapy apparatus has the advantages that thebacklight LCD is arranged, the channels A / B can be controlled to simultaneously or respectively output, the intensity can be adjusted, a plurality of affected parts can be treated at the same time, and the use is very convenient.

Description

technical field [0001] The invention relates to the field of medical electronic equipment, in particular to a low-frequency therapeutic instrument with dual independent modes. Background technique [0002] Most of the low-frequency therapeutic instruments currently on the market use low-frequency oscillation, voltage regulation and frequency doubling, output intensity control, or low-frequency oscillation, signal amplification, transformer boosting and other technologies to generate adjustable high-voltage direct current pulses. The human body produces stimulation, using Chinese acupuncture and moxibustion points, has a certain effect on cervical syndrome, muscle contraction, rheumatic pain, etc. and relieves pain. And health care function, electrical stimulation can dredge acupuncture points and meridians and wake up suspended pore cells, and promote the recovery of nerve cells, but because the muscles controlled by peripheral nerves are in a paralyzed state after injury, w...

Problems solved by technology

[0002] Most of the low-frequency therapeutic instruments currently on the market use low-frequency oscillation, voltage regulation and frequency doubling, output intensity control, or low-frequency oscillation, signal amplification, transformer boosting and other technologies to generate adjustable high-voltage direct current pulses. The human body produces stimulation, using Chinese acupuncture and moxibustion points, has a certain effect on cervical syndrome, muscle contraction, rheumatic pain, etc. and relieves pain. And health care function, electrical stimulation can dredge acupuncture points and meridians and wake up suspended pore cells, and promote the recovery of nerve cells, but because the muscles controlled by peripheral nerves are in a paralyzed state after injury, when sports are injured, they lose the sense of controlling muscles. Electrical stimulation and dredging of the meridians by therapeutic instruments can significantly improve the curative effect, but the market generally has a single-channel output, which cannot treat multiple affected areas at the same time, so its application is limited
