Title:
LIPID CONCENTRATION MEASURING DEVICE, PROGRAM, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/138902
Kind Code:
A1
Abstract:
[Problem] To provide a device and method capable of measuring blood lipid concentration. [Solution] This lipid concentration measuring device includes: a radiating unit which radiates light onto a predetermined position of a specimen; a light receiving unit which detects the intensity of light emitted from the specimen, in a plurality of positions that are separated a prescribed spacing from the position at which the light is radiated by the radiating unit, or that are consecutive therewith; and a control unit which calculates a blood turbidity from the light intensity at the plurality of positions, calculates a turbidity change amount from the blood turbidity on the basis of correlation data between the elapsed time after a meal and the blood turbidity, created in advance by means of statistical processing, calculates a lipid concentration change amount from the turbidity change amount on the basis of correlation data between the turbidity change amount and a lipid concentration change amount, created in advance by means of statistical processing, and calculates a lipid concentration absolute value estimated amount by adding the lipid concentration on an empty stomach to the lipid concentration change amount.
