Abstract:
1. A blood glucose measurement system comprising: an invasive blood glucose measurement apparatus; and a non-invasive blood glucose measurement apparatus; wherein the invasive blood glucose measurement apparatus includes: a blood sampling component that collects blood from the body on the basis of an invasive measurement command from the non-invasive blood glucose measurement apparatus; and a blood glucose level measurement component that measures a blood glucose level from blood collected by the blood sampling component, wherein the non-invasive blood glucose measurement apparatus calibrates a measured blood glucose level by using a blood glucose level measured with the invasive blood glucose measurement apparatus, wherein the non-invasive blood glucose measurement apparatus has: a controller that outputs a non-invasive actuation signal that instructs the non-invasive blood glucose measurement apparatus to detect a characteristic quantity in the body, and an invasive actuation signal that instructs the invasive blood glucose measurement apparatus to begin measuring a blood glucose level; a characteristic quantity detector that detects the characteristic quantity in the body on the basis of the non-invasive actuation signal; a blood glucose level estimator that finds an estimated blood glucose level on the basis of the characteristic quantity detected by the characteristic quantity detector; an invasive blood glucose information memory that stores blood glucose measurement information including a blood glucose level measured by the invasive blood glucose measurement apparatus; a blood glucose level calibration calculator that calculates calibration data for calibrating the estimated blood glucose level on the basis of the blood glucose measurement information stored in the invasive blood glucose information memory and the estimated blood glucose level found by the blood glucose level estimator; a blood glucose level calibrator that calibrates the estimated blood glucose level found by the blood glucose level estimator on the basis of the calibration data; a non-invasive blood glucose level display component that displays the estimated blood glucose level calibrated by the blood glucose level calibrator; and an invasive measurement command component that receives the invasive actuation signal outputted from the controller and instructs the invasive blood glucose measurement apparatus to measure the blood glucose level, wherein the controller outputs the invasive actuation signal when the difference between the estimated blood glucose level and the blood glucose level measured by the invasive blood glucose measurement apparatus during calibration has reached or exceeded a preset non-invasive blood glucose threshold.
