Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of body surface infrared radiating light spectrum detection method and instrument of wide cut.
Background technology
In recent years, both at home and abroad the report of relevant acupuncture points on the human body Infrared Physics characteristic research seldom, research means still stays in the Infrared Thermography Technology level.Infrared Thermography Technology is mainly used to the Temperature Distribution that human body body surface thermal radiation forms, can not do infrared spectrum analysis, and it is high that sensitivity is owed, so can not detect the faint characteristic acupuncture point spontaneous infrared radiation of covering in the thermic infra-red radiation of body surface temperature.Therefore, adopt the new and high technology means of Infrared Physics, invent new infrared radiometer device and carry out acupuncture point Infrared Physics characteristic research and seem very necessary.
Tellurian all objects are when temperature is higher than absolute zero, and its inner molecule will produce infra-red radiation because of warm-up movement.Different objects is under different temperature, and the wavelength and the intensity of its infra-red radiation also have nothing in common with each other.The infra-red radiation of human body can reflect the metabolic alterations of human internal organ and each one of whole body.The acupuncture point is the position that viscera QI of channels and collaterals infusion is come in and gone out, also be human body and extraneous window of getting in touch communication, the infra-red radiation of acupuncture points on the human body and transmission characteristic should be able to reflect the state of cave district QI and blood infusion operation from a side, and then the physiological activity and the pathological change of reflection internal organs organ.Therefore, to the detection of acupuncture points on the human body infra-red radiation and the further investigation of transmission characteristic, a series of essential problems such as energy and information transmission conversion are significant when stinging moxibustion to disclosing acupuncture points on the human body, also provide new research means and theoretical foundation for improving the acupuncture clinical efficacy and explaining acapuncture action mechanism simultaneously.
Still the report that does not have acupuncture point and moxa-moxibustion infrared spectroscopic study and instrument development at present both at home and abroad.
Summary of the invention
