Abstract

The present invention relates to a method and apparatus for correction of non-invasive blood glucose measurement, and more specifically, to a method for correcting a blood glucose signal measured from a video image of the white light reflected from the skin. The present invention provides a method and apparatus for measuring the exact amount of blood glucose in blood by extracting fundamental blood glucose signals. The method may comprise the steps of irradiating white light on the skin by using a white light source, filtering the white light reflected from the skin by a first wavelength filter and a second wavelength filter, obtaining a first signal including a blood glucose signal and a pulse signal based on a video image generated by the white light filtered by the first wavelength filter, obtaining a second signal including a pulse signal based on a video image generated by the white light filtered by the second wavelength filter, obtaining a blood glucose signal by subtracting the second signal from the first signal, and calculating the amount of blood glucose in a subcutaneous blood vessel based on the obtained blood glucose signal. According to the method and apparatus for correction of non-invasive blood glucose measurement disclosed in the present invention, fundamental blood glucose signals can be extracted in real time by a method that does not collect blood.

Description

technical field [0001] The present invention relates to a method and apparatus for correcting blood glucose measurements of subcutaneous blood vessels, and more particularly to a method and apparatus for correcting signals other than blood glucose signals by subtracting signals based on white light reflected from the skin and equipment. Background technique [0002] Generally, blood sugar refers to the glucose contained in the blood. The human body must maintain a certain amount of blood sugar to maintain life, and high blood sugar can induce diabetes. By measuring the amount of blood sugar in the blood, you can know whether a certain amount of blood sugar is maintained. In cases where measured blood sugar levels are outside the normal range, appropriate measures can be taken to maintain health. [0003] Methods of performing blood glucose measurement in a living body are generally classified into invasive methods and non-invasive methods. The invasive method refers to a...
