発明の名称 (英語) NON-INVASIVE BLOOD GLUCOSE LEVEL MEASUREMENT METHOD AND NON-INVASIVE BLOOD GLUCOSE LEVEL MEASUREMENT DEVICE コモンズ
発明の概要(英語) This non-invasive blood glucose level measurement device (1) is provided with: a pulse waveform measurement unit (2) having FBG sensors (4) for measuring an acceleration of pulse waveform of a test subject; and a data-processing unit (3) for calculating the blood glucose level of the test subject at the point in time of measurement of the acceleration of pulse waveform, from waveform information of the measured acceleration of pulse waveform, on the basis of a predetermined correlation relationship. The correlation relationship is a standard curve constructed by carrying out a PLS regression analysis, using the blood glucose level measured by a non-invasive method as the objective variable, and a simultaneously-measured acceleration of pulse waveform as the explanatory variable. A non-invasive blood glucose level measurement device capable of measuring blood glucose level at about the same measurement accuracy as an invasive blood glucose level measurement device can be achieved thereby.
