Design Of Laser Acupuncture Instrument Based On SCM And Study On Implementation Of Moxibustion

The research and development of the modern acupuncture therapeutic instruments have stepped in a developmental and associated way of modern technology stage by stage. Especially intelligent instruments with perfect performance and great functions are the important association of both modern instruments technologies and the traditional acupuncture theories and experiences, which are based on traditional Chinese medicine theory and combined with computers, micro-electronics and laser technologies. The laser acupuncture instrument in this paper is based on single chip and associated by semiconductor laser technology, which is superior to traditional acupuncture and has many excellences like low cost,smart application and convenient operation with some shortcoming recuperated like large capacity and weight. It also covers the shortages of continuous irradiation or that of simple disciplinary stimulate signal which is controlled by some simple electronic circuit can be easily adapted to. And the realization of reinforcing and reducing of moxibustion is a technological innovation in traditional moxibustion coming true in engineering. This paper discusses the biologic effect of laser acupuncture, tests the spectra and researches into the mechanism about several kinds of light therapeutic instruments sold in market, after the generation and development history, actualities and subsistent problems of laser acupuncture are introduced. Traditional moxibustion including reinforcing and reducing is implemented by applying chaos method to control the duty cycle of moxibustion signal, which is based on the traditional Chinese medicine and modern dynamic deep level stimulating theories, and software and hardware are designed at the end. In sum, this paper chooses several representative infrared and visible light therapeutic instruments to test their spectra and researches into the mechanism by using three precision spectrophotometers which are the same in structure and fundamental, but different in wave band. The luminescence power of semiconductor laser diode is tested after the radiator element of laser diode is made and the drive circuit is designed. Then, chaos mathematic model is introduced to produce deterministic class stochastic signal and C langrage program, which is based on the hardware circuit design of MSP430, is designed and on-line debugged to implement the dynamic stimulation effect and avoid the body adaptability with the duty cycle of chaos sequence. The duty cycle is adjusted and controlled to accomplish the reinforcing and reducing in moxibustion. At last, Average power of laser diode is tested under the conditions of different duty cycles and the waveforms are collected by applying virtual instrument.
