The Development Of Synthetic Leg Physiotherapy Based On Microcomputer Unit

This paper proposes a method of traditional Chinese medicine combined with a variety ofphysical factors in the treatment of leg pain According to the mechanism of physical factorsleg disease treatment, and developed an instrument for the treatment of leg pain disordersbased on a variety of physical factors. The instrument combines the aerodynamic physicalmassage, heat therapy, electrical stimulation therapy, to achieve a variety of treatments, andhas heating protection. Paper is divided into the overall function of the system design,hardware design, software design and system testing four parts.The system is designed to be built based on the analysis of the treatment on the leg,including the use of intermittent massage pump and valve work to achieve the contraction andexpansion of the airbag pneumatic massage physical, infrared heat therapy around thetemperature field of electric heating, electrical stimulation used as a physical factor react in thetreatment of leg body electric pulse therapy.Hardware circuit design mainly includes the use of internal resources ATmega48microcontroller, the power supply circuit design, the drive control circuit of the heating, thepump valve driving circuit, high voltage electrical pulses required for the stimulation of thebooster circuit, electrical stimulation of the human body discharge circuit and the realization ofhuman-computer interaction buttons and the display circuit. System software design includes aresponse to the input keys, each module working hours be set and working conditions display,PWM pulse width modulation to be used to change the heating current, the internalmicrocontroller interrupt timer is used to control the pump, valve work and realized workinghours, and a wide range of digital boost programs and three pulse waveform control programbe designed, the supply voltage is raised to50V-150V and short-term storage in the capacitor,and discharge procedures to be used for intermittent skin contact with electrical stimulationpulses to realize the strength of three models and a variety of treatments.Each module in the system were to be carried out functional testing, which boost anddischarge section conducted several tests corrected, continue to refine and improve the program, to achieve a variety of modes electrical stimulation treatments stability.Compatibility of each module is tested on the test machine, the expected function is obtained,the product has a good promotion prospects.
