Abstract
Description
以下、図1~図5を用いて、本発明の第1の実施形態である自動分析装置100Aの構成及び動作を説明する。
まず、図5を用いて、No.1の反応容器3における洗浄動作を説明する。図4を用いて説明したように、第1番目のサイクルから第9番目のサイクルにおいて通常の洗浄が実施される。
次に、図5を用いて、No.2の反応容器3における洗浄動作を説明する。第2番目のサイクルから第10番目のサイクルにおいて通常の洗浄が実施される。なお、No.2の反応容器3の洗浄を開始するタイミングは、No.1の反応容器3と比較して、1サイクル分遅れている。
次に、図6~図7を用いて、本発明の第2の実施形態である自動分析装置100Bの構成及び動作を説明する。
検体サンプリング機構5が、特別な洗剤を反応容器3へ吐出するようにしてもよい。この場合、特別な洗剤はサンプル容器1と同様の容器に充填され、サンプルディスク2に設置される。
第1及び第2の実施形態では、計数部201aが特定の試薬項目に対し反応容器3毎の使用回数をカウントして記憶部202に記憶する。ここで、特別な洗剤を用いて反応容器3の洗浄が実施された場合、反応容器3が交換された場合等、所定の動作が実施された場合に、記憶部202に記憶された使用回数をリセットしてもよい。
また、特別な洗剤による洗浄を実施するか否かの基準となる、特定の試薬項目についての使用回数の閾値を複数設けてもよい。例えば2個の閾値をN1、N2(N1<N2)とした場合、使用回数がN1を超えた場合には、使用回数がN1を超えた反応容器について測定中には特別な洗浄が実施されず、測定終了後に新たな測定依頼が無ければ、特別な洗浄が実施される。測定終了後に新たな測定依頼が有れば、特別な洗浄は実施せず、使用回数がN1を超えた反応容器を用いてそのまま新たな測定依頼に対する測定を実施する。一方、使用回数がN2を超えた場合には、使用回数がN2を超えた反応容器について測定終了後に新たな測定依頼が有っても新たな測定を割り当てないで、特別な洗剤による洗浄が実施される。
反応容器3毎に特別な洗剤による洗浄の実施回数を記憶し、表示装置に表示してもよい。また、反応容器の交換タイミングや、その交換タイミングの閾値を表示装置に表示された画面を介して入力装置で変更可能にしてもよい。
