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.

By promoting the socialization of hospital logistics professional skill services, the logistics support ability and safety production supervision level can be improved. By using the theory and method of system dynamics, the income decision model of public-private-partnership projects in the energy station of Nankai hospital is established. Then, the qualitative factors in the decision-making model are transformed into calculable quantitative factors by using the mathematical method of fuzzy logic, and the reasonable charging interval negotiated between Nankai Hospital and the project company is given. According to the income range and in consideration of the balance of interests of all stakeholders, the concession period and the concession price are adjusted to provide decision-making and analysis reference for energy station construction projects.
