双波长多通道激光针灸仪的设计与实现

Design of a dual wavelength multi-channel laser acupuncture instrument

目的利用弱激光的生物刺激效应，针对中医针灸穴位配伍的临床应用特点，在中医针灸理论指导下设计一种双波长多通道激光针灸仪。方法采用单片机与半导体激光器设计硬件电路，以实现仪器的基本功能，并设计相应的上位机软件。结果所设计的激光针灸仪可对多个穴位同时进行相同或不同激光参数（波长、功率密度、连续，脉冲）的激光针灸治疗，每个通道均可输出635、808nm两种波长的激光，且激光功率连续可调。结论双波长多通道激光针灸仪实现了对针刺疗法中提、插等手法以及艾灸疗法中小炷、中炷、大炷等灸法的模拟，可满足针灸临床治疗中对穴位配伍、量化治疗参数及电子病历管理等多方面需求，操作简单，使用方便，具有良好的临床应用价值。

Objective To design a laser acupuncture instrument with dual wavelength and multi-channel, under the guidance of traditional Chinese medicine acupuncture theory and according to low-level laser induced effect in bio-tissues and compatibility characteristics of acupuncture points. Methods Using SCM and semiconductor laser, hardware circuitry was designed to achieve the basic functions of the instrument, and the corresponding PC software was developed. Results The laser acupuncture treatment for several acupuncture points could be carried out at the same time with the same or different laser parameters （wavelength, power density, continuous/pulse）, and each channel could output 635 nm and 808 nm laser, with continuous adjustable power. Conclusions The dual wavelength multi-channel laser acupuncture instrument can meet the needs of compatibility during clinical acupuncture treatment and is easy to operate.
