(1-1)装置構成
図1に、自動分析装置100の構成例を示す。操作部102はコンピュータ(CPU、記憶部、インターフェース)を有し、分析部を含む自動分析装置100の動作を制御する。CPUは、プログラムの実行により分析部の動作を制御する制御部として機能する。操作部102は、付属するディスプレイ101に各種の情報を表示し、オペレータに自動分析装置100の状態を通知する。また、操作部102は、ディスプレイ101に各種の操作画面を表示し、操作画面に対するオペレータの操作入力を通じて自動分析装置100の動作を制御する。
・ある患者から採取した検体に含まれる成分が別の患者から採取した検体の測定に影響しないようにするため。
・ある項目の測定と別の項目の測定との間で試薬に含まれる成分が影響しないようにするため。
図2に、反応槽水の交換の実行を指示する際に使用される画面(メンテナンス実行指示画面201)の一例を示す。メンテナンス実行指示画面201には、メンテナンスの「実行」を指示する実行ボタン202と、メンテナンスの実行を行なわずに画面を閉じるキャンセルボタン203と、メンテナンスを実行する分析部を指定する分析部1ボタン205及び分析部2ボタン206と、時間差メンテナンス指定チェックボックス204とが配置されている。時間差メンテナンス指定チェックボックス204にチェックを入れるか否かでメンテナンスの実行時の動作が変更される。
(1-3-1)通常時
図3に、時間差メンテナンス指定チェックボックス204(図2)にチェックが入っていない場合に実行される動作の流れを示す。制御部(CPU)は、実行ボタン202が押されたことを検知すると(実行ボタン押下処理301)、時間差メンテナンス指定チェックボックス204のチェック状態の読取処理302を実行する。
図4に、時間差メンテナンス指定チェックボックス204(図2)にチェックが入っている場合に実行される動作の流れを示す。制御部(CPU)は、実行ボタン202が押されたことを検知すると(実行ボタン押下処理401)、時間差メンテナンス指定チェックボックス204のチェック状態の読取処理402を実行する。

本実施例では、自動分析装置100が3台以上の分析部を有する場合について説明する。図6に、本実施例で使用されるメンテナンス実行指示画面601の一例を示す。メンテナンス実行指示画面601には、メンテナンスの「実行」を指示する実行ボタン602と、メンテナンスの実行を行なわずに画面を閉じるキャンセルボタン603と、メンテナンスを実行する分析部を指定する分析部1ボタン605及び分析部2ボタン606と、分析部3ボタン607と、時間差メンテナンス指定チェックボックス604と、同時実行の対象範囲を選択するメニューボックス608とが配置されている。時間差メンテナンス指定チェックボックス604と、図2の時間差メンテナンス指定チェックボックス204とは同じ機能を意味する。
前述の実施例では、メンテナンス実行指示画面201、601を通じ、オペレータが時間差メンテナンスを実行するか否かを指示していたが、予めオペレータによって設定された「水供給量」と「必要量」とに基づいて、制御部(CPU)が、時間差メンテナンスを実行するか否かを自動的に設定するようにしてもよい。
本発明は、上述した実施例に限定されるものでなく、様々な変形例を含んでいる。例えば、上述した実施例は、本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備える必要はない。また、ある実施例の構成の一部を他の実施例の構成に置き換えることができる。また、ある実施例の構成に他の実施例の構成を加えることもできる。また、各実施例の構成の一部を削除することもできる。
