図1は、本発明の一実施形態に係る血糖測定装置100の外観構成を示す図である。図1に示すように、血糖測定装置100は、測定装置本体部110と、測定装置本体部110に装着される測定用チップ120とを備える。
次に、血糖測定装置100の測定装置本体部110の機能構成について説明する。図2は、血糖測定装置100の測定装置本体部110の機能構成を示す図である。
次に血糖測定装置100、情報処理端末及びRFIDリーダ/ライタにおける静的限値設定処理の流れについて図3A、図3B及び図4を用いて説明する。図4は、病院等において医師等が取り扱う情報処理端末400に接続されたRFIDリーダ/ライタ410に対して、血糖測定装置100をかざすことで、血糖測定装置100に静的限値を設定する様子を示した図である。また、図3A及び図3Bは、血糖測定装置100及び情報処理端末400における静的限値設定処理の流れを示す図である。
次に血糖測定装置100における動的限値設定処理の流れについて図5を用いて説明する。図5は、動的限値設定処理の流れを示す図である。
次に、血糖測定装置100における血糖測定処理の流れについて図6A、図6Bを用いて説明する。図6A及び図6Bは、血糖測定装置100における血糖測定処理の流れを示すフローチャートである。
上記第1の実施形態では、静的限値の設定に際してRFIDリーダ/ライタを用いる構成としたが、本発明はこれに限定されず、無線送信により静的限値を送信できる構成であれば他の方式であってもよい。
