METHOD FOR MEASURING CONCENTRATION OF BLOOD COMPONENTS WITHOUT DRAWING BLOOD AND APPARATUS THEREFOR

摘要

PURPOSE: Provided are a method for measuring concentration of blood components without drawing blood and an apparatus therefor by using a multi-colored light source emitting specific light of 800-1850nm in the area of fore infrared rays, as a light source. CONSTITUTION: The method comprises the steps of: providing power supply to a light source, a microprocessor, a plurality of light detectors, a plurality of analog/digital converter and a display; emitting fore infrared rays of 800-1850nm using the light source; condensing the fore infrared rays through a reflector and a condensor then radiating it to the skin; collecting the fore infrared rays having information about blood components then inducing it to a plurality of spectrum selection parts; converting the light with at least three waves output from the spectrum selection parts into an analog electric signal; amplifying the analog electric signal; converting the amplified the analog signal to a digital signal by using the analog/digital converter then transmitting it to the microprocessor; calculating the concentration of blood components; and displaying the calculation results.
