Claims (11)
- 1次注入ラインに接続された1次容器、および2次注入ラインを通して1次注入ラインに接続された2次容器から、流体を注入可能な注入ポンプを含む注入システムにおいて、不具合状態を判断するシステムにして、2次注入ラインが、2次注入ライン内の2次流体の流れを制御する弁を有し、前記1次注入ラインが1次容器と、2次注入ラインの1次注入ラインへの接続部との間に配置された逆止め弁を有し、該逆止め弁が、1次注入ラインから1次容器への逆流を阻止するシステムであって、該システムが、
2次注入ラインの1次注入ラインへの接続部の下で1次注入ラインに隣接して配置された圧力センサにして、1次注入ライン内の圧力を測定するために、1次注入ラインで動作する配置構成にあり、1次注入ライン内の圧力を表す信号を提供する圧力センサと、
圧力に関連した値を記憶するメモリと、
メモリと通信し、圧力センサによって提供された信号に応答するプロセッサとを有し、該プロセッサが、圧力信号をサンプリングして、基線圧力値を確立し、基線圧力値をメモリに記憶し、基線圧力値を後にサンプリングする圧力値と比較するようプログラム化され、さらに、後にサンプリングした圧力値が選択した圧力閾値以上である場合は、不具合状態が存在するという警報を提供するようにしたシステム。 - プロセッサが、後にサンプリングした圧力値を圧力閾値と比較する前に、後にサンプリングした圧力値の時間が測定ウィンドウ内であるか判断する請求項1に記載のシステム。
- 測定ウィンドウが開始境界と終了境界を有し、後にサンプリングした圧力値が、開始境界と終了境界内の時間にサンプリングされ、後にサンプリングした圧力値が選択した圧力値以上である場合に、警報が提供される請求項2に記載のシステム。
- プロセッサがさらに、基線圧力値を確立した後に、流体の塊を1次注入ラインに注入する逆モードで注入ポンプを操作するようにプログラムされる請求項1に記載のシステム。
- プロセッサは、後にサンプリングした圧力値が選択した圧力閾値より低い場合に、流体の塊を1次注入ラインに注入する逆モードで注入ポンプを操作するようにプログラムされる請求項1に記載のシステム。
- プロセッサが、注入ポンプを逆モードで操作した後に、圧力センサから受信した圧力信号をサンプリングし、圧力信号を分析して、圧力信号が表す圧力波の特徴を判断し、その特徴を記憶した基線圧力値と基線特徴と比較して、特徴が選択された閾値以上である場合に、不具合状態が存在することを示す警報を提供するようにプログラムされる請求項5に記載のシステム。
- 特徴が選択された閾値未満である場合に、機構チェックの警報を介護者に提供する請求項6に記載のシステム。
- 注入システムの不具合状態を判断するシステムにして、前記注入システムが流体を1次注入ラインに接続された1次容器、および2次注入ラインを通して1次注入ラインに接続された2次容器から注入することができる注入ポンプを含み、2次注入ラインが、2次注入ライン内の2次流体の流れを制御する弁を有し、1次注入ラインが、1次容器と、2次注入ラインの1次注入ラインへの接続部との間に配置された逆止め弁を有し、該逆止め弁が1次注入ラインから1次容器に向かう流れを防止するシステムであって、該システムが、
2次注入ラインの1次注入ラインへの接続部の下で1次注入ラインに隣接して配置された圧力センサにして、1次注入ライン内の圧力を測定するために1次注入ラインと動作する配置構成を有し、1次注入ライン内の流体圧力を表す信号を提供する圧力センサと、
圧力に関連した値を記憶するメモリと、
該メモリと通信し、圧力センサによって提供される信号に応答するプロセッサとを有し、該プロセッサが、圧力信号をサンプリングして、基線圧力値を確立して、メモリ内に基線圧力値を記憶し、基線圧力値を後の時間にサンプリングされる圧力値と比較するようプログラムし、さらに前記1次注入ラインの圧力を増大すべく前記ポンプを作動した後にサンプリングされる圧力値が選択した圧力閾値以上である場合に、不具合状態が存在するという警報を提供するようにしたシステム。 - プロセッサが、1次注入ライン内の圧力を増加させるために、逆モードでポンプを操作する請求項8に記載のシステム。
- 1次注入ラインに圧力を加える制御可能な装置をさらに含み、該装置が注入ポンプの取り入れ部と、2次注入ラインを1次注入ラインに接続するコネクタとの間に配置される請求項9に記載のシステム。
- 制御可能な装置が、プロセッサからの信号に応答して、1次注入ラインに圧力を加える請求項10に記載のシステム。
