摘要
The present invention relates to a non-invasive glycated hemoglobin measurement system and method using photon diffusion theory. According to the present invention, in the non-invasive glycated hemoglobin measurement system using photon diffusion theory, first to third LEDs, first to third LEDs having different first to third wavelength values, and positioned on one side of the body of a subject to be measured 3 A photodetector that measures the intensity of light transmitted from the LED, and transmittance or reflectivity including the total absorption coefficient and scattering coefficient for the wavelengths of the first to third LEDs according to the photon-diffusion theory. obtain an equation for , and obtain two ratio equations for transmittance or reflectivity according to two wavelengths among a plurality of different wavelengths using the obtained equation for transmittance or reflectivity, respectively, and then the obtained two ratio equations and a calculation unit for calculating the concentrations of glycated hemoglobin (HbA1c) and arterial blood oxygen saturation (SpO2) of the subject to be measured in combination with the . As described above, according to the present invention, the concentration of glycated hemoglobin (HbA1C) is non-invasively measured using the rate of change of intensity of LED light having three different wavelengths, but according to the photon diffusion theory, the rate of change in intensity of light to which the transmittance of LED light is applied or the LED The concentration of glycated hemoglobin (HbA1C) and arterial blood oxygen saturation (SpO2) can be measured accurately and simply through the rate of change of light intensity to which the light reflectance is applied.
