PROBLEM TO BE SOLVED: To display change of a blood glucose level in a manner that a user can easily understand.SOLUTION: The invention is configured so that, a line which indicates a change state of a blood glucose level between respective zones determined by adjacent two measurement times, in respective date of last month in which, per day, the blood glucose level is measured plural times, is displayed in which, the zone in which change of the blood glucose level is larger than a threshold, is displayed with a red color, the zone in which the blood glucose level is reduced is displayed with a blue color, and the zone in which the blood glucose level is not reduced, but change of the blood glucose level is equal to or less than the threshold, is displayed with a gray color, on a same single chart. A doctor can understand that, there are many red color zones in morning, and can grasp tendency of a control state of the blood glucose level of the patient, namely, it is possible to display change of the blood glucose level in a manner that a user can easily understand.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2016,JPO&INPIT【課題】血糖値の変化を理解しやすく表示する。【解決手段】1日に複数回血糖値を測定した過去1カ月の各日の隣り合う2つの測定時刻により定まる各区間の血糖値の変化状態を示す線を、血糖値の変化が閾値より大きい場合には当該区間の線を赤色で、血糖値が減少している場合には当該区間の線を青色で、血糖値が減少していないが血糖値の変化が閾値以下の場合には当該区間の線を灰色で、同じ1つのグラフに表示する。ドクターは、朝方に赤色が密集していることが理解でき、当該患者の血糖値のコントロール状態の傾向を把握することができる。このように、血糖値の変化を理解しやすく表示することができる。【選択図】図7
