Blood glucose measuring device and method of measuring average postprandial blood glucose
First Claim
1. A blood glucose measuring device, comprising:
- a storing unit that stores calibration data indicating a correlation between a postprandial urinary glucose at a predetermined time after meal and a time-averaged postprandial blood glucose through a period up to said predetermined time after meal;
a measuring unit that measures postprandial urinary glucose from urine of a subject at said predetermined time after meal;
a processing unit that calculates said time-averaged postprandial blood glucose, based on said postprandial urinary glucose measured; and
an output unit that outputs data indicating said postprandial blood glucose calculated,wherein said correlation between said postprandial urinary glucose and said time-averaged postprandial blood glucose is maintained in a case where water intake or excretion takes place in said subject through drinking water or perspiration.

Abstract
A practical measuring device and a measuring method that allow simply measuring average postprandial blood glucose from urinary glucose. The blood glucose measuring device includes a measuring unit that measures postprandial urinary glucose from subject'"'"'s urine at a predetermined time after meal, a processing unit that calculates average postprandial blood glucose through a period up to the predetermined time after meal, based on the postprandial urinary glucose, a storage unit that stores calibration data including the postprandial urinary glucose and the average postprandial blood glucose in association, and an output unit that outputs data indicating the calculated average postprandial blood glucose. The processing unit calculates the average postprandial blood glucose, based on the postprandial urinary glucose from the urine of the subject who has intaken a desired amount of water or perspired in the period up to the predetermined time after meal, and the calibration data.
