memory)などの半導体メモリ等により構成され、製剤の使用期限データ等を記録する。ROMは、マイクロプロセッサ23により実行されるソフトウェアプログラムや固定データを予め格納されている。RAMは、投与時刻・投与量など投与に関するデータや、使用時間カウントデータ、演算に使用するデータ及び演算結果等を一時的に記憶するいわゆるワーキングメモリとして使用される。RAMは、電源バックアップされることにより、又はEEPROMにも上記データの一部若しくは全部を記憶することにより、電源ボタン6OFF後も、予め定められた製剤の使用期限データなどを記憶している。
図10は、本発明の実施の形態2に係る製剤を自動溶解させる薬剤投与装置の内部断面図である。図6と同一構成部分には同一符号を付して重複箇所の説明については、ここでは省略する。
定められている。また、薬剤投与装置1は、粉末製剤44aと薬液44cとを自動又は半自動で溶解させることができる。したがって、薬剤投与装置1は、製剤溶解時を使用開始時としてタイマ21(マイクロプロセッサ23の内蔵タイマ21Aでもよい)をスタートさせることで、有効使用期間の管理が可能となる。
