Noninvasive HbA1c Measurement System Using the Beer-Lambert law and Method Thereof

摘要

The present invention relates to a non-invasive glycated hemoglobin measurement system and method using Beer-Lambert's law. According to the present invention, the first to third LEDs having different first to third wavelength values are positioned on one side of the subject's body, and irradiating light with a photodetector positioned at the opposite point, the step of Acquiring the light intensities of the first to third LEDs measured by the light detection unit, respectively, and when the second LED and the third LED are transmitted, the ratio of the absorbance and the first LED and the third LED are transmitted When the ratio to each absorbance and the light intensity of the first to third LEDs measured by the photodetector are applied to Beer-Lambert's law, the concentrations of the glycated hemoglobin (HbA1c) and arterial blood oxidative saturation (SpO2) of the subject are determined. extracting. As described above, according to the present invention, the concentration of glycated hemoglobin (HbA1C) can be measured non-invasively using LED lights having three different wavelengths, and the LED calculated using the Beer-Lambert Law The concentration of glycated hemoglobin (HbA1C) and arterial blood oxidative saturation (SpO2) can be measured accurately and conveniently through light absorbance.
