Blood glucose measurement system

A non-invasive blood glucose measurement apparatus in which a measured non-invasive blood glucose level is calibrated using a blood glucose level measured with an invasive blood glucose measurement apparatus that collects blood from the body and measures the blood glucose level on the basis of an invasive measurement command, the apparatus comprising:

• a controller that outputs a non-invasive actuation signal that instructs the non-invasive blood glucose measurement apparatus to begin measuring a blood glucose level, and an invasive actuation signal that instructs the invasive blood glucose measurement apparatus to detect a characteristic quantity in the body;
• a characteristic quantity detector that detects a 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 and calibration data (discussed below);
• a blood glucose level calibration calculator that calculates calibration data from the blood glucose measurement information, including blood glucose levels, measured by the invasive blood glucose measurement apparatus, and the estimated blood glucose level found by the blood glucose level estimator;
• and
• an invasive measurement command component that receives an invasive measurement command signal outputted from the controller when the amount of change in the estimated blood glucose level during calibration has reached or exceeded a preset non-invasive blood glucose threshold, and instructs the invasive blood glucose measurement apparatus to measure the blood glucose level.

A blood glucose measurement system comprises:

• [i] an invasive blood glucose measurement apparatus having:
• 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;
• and
• [ii] a non-invasive blood glucose measurement apparatus with which a blood glucose level measured is calibrated by using a blood glucose level measured with the invasive blood glucose measurement apparatus, wherein the apparatus having:
• a controller that outputs a non-invasive actuation signal that instructs the non-invasive blood glucose measurement apparatus to begin measuring a blood glucose level;
• a blood glucose level estimator that finds an estimated blood glucose level for the body on the basis of the non-invasive actuation signal;
• a blood glucose level calibration calculator that calculates calibration data for calibrating the estimated blood glucose level;
• 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;
• an invasive measurement command component that receives an invasive measurement command signal outputted from the controller, and instructs the invasive blood glucose measurement apparatus to measure the blood glucose level;
• and
• a notification component that notifies the invasive blood glucose measurement apparatus to begin measurement of a blood glucose level when the amount of change in the estimated blood glucose level during calibration has reached or exceeded a preset invasive blood glucose threshold.
