Research And Practice On Detection Massager Of Foot Acupoint On Paralysis Patients

Through Chinese medical science thousands of years’study,there are12meridian lines thoughout our body,all of those meridian lines reach the feet. The meridian lines are connected by countless acupoints.The Meridian can get dredged and thedisease can be cured by stimulating the the meridian acupoint in the soles.The modern electronic technique has been showed more superiority and practicality in the detection of the foot points.Now a large amounts of foot massager can not develop the advantage of modern electronic technique.They massage the soles of the feet as a whole,instead of massaging the the single acupoint. Through the actual survey,they can not achieve the desired therapeutic effect,so their practical effect were poor. For those problems, this article presents a practical and reliable solution.Firstly,we make the organization section of foot massage based on the feet shape.The organization section including the aluminium massage support, the signal acquisition system, the stepping motor and its orbits. The aluminium massage support is composed by insulating panel,434pair of copper sounding heads and the massage heads. The signal acquisition system is composed by a sensor and signal acquisition board. The foot points signal which collected by the sensor can be transerred to the signal acquisition board, then the main control panel send order to the stepping motor.The stepping motor parts including the stepping motor, the X, Y direction orbit, and driving system.In order to acquire the resistance of the feet acupoint, I studied electrophysiological properties of the skin, and the foot can be connected to the circuit as a resistance by using the R-C equivalent circuit model.Meanwhile, I desgined a headware circuit to choose the signal,deal with the data and move the stepping motor.It achieved the collect of the feet signal, the locate of the acupoint confirmation, and the locate of the oscillator! use32fixed point DSP-TMS320F2812controller IC to achieve the design of hardware curcuit part.To achieve control of the system, I use C programming language for the preparation of the DSP program. And then I use the DSP specialized programming simulation software CCS to achieve the simulation and download the program.The CCS help me to achieve the F2812port initialization,the choice of multiple signals and the driving of the stepper motor.In order to make the control of the system visually, I used VC++to design the PC interface.At last,the software achieved the data processing and showed the result in the interface operation. This system has proved the veracity and feasibility of the system about the detect and massage of the foot acupuncture point in paralysis patinet by experimenting many people and analyzing the error results.And then send the order about the stepping motor,preliminarily accomplished the automatic positioning and shift function.At the same time has checked the accuracy and feasibility of the instrument.
