Design of a dual wavelength multi-channel laser acupuncture instrument / 国际生物医学工程杂志

ABSTRACT

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.
