Description
上記基礎出願により開示された内容は、本願の明細書と請求の範囲と図面に引用されているものである。
また、本発明の他の態様の内視鏡用管路切換装置は、内視鏡に設けられ気体流通管路と液体流通管路を含む複数の管路が接続されるシリンダと、このシリンダに進退自在に嵌挿され、通常位置とこの通常位置よりシリンダの内側に押し込まれる押し込み位置との間で移動されるピストンと、このピストンを前記通常位置に向けて付勢する付勢部材と、を有しており、前記通常位置から前記押し込み位置に移動させることで前記気体流通管路を閉塞して前記液体流通管路を連通するよう、前記複数の管路の連通状態を切り換える内視鏡用管路切換装置において、前記シリンダと前記ピストンのいずれか一方に設けられ、前記ピストンが通常位置もしくは押し込み位置にある場合に、前記シリンダと前記ピストンのいずれか他方の壁面に弾性的に接触して前記気体流通管路と外部とを隔離するシール部材と、前記他方の壁面に設けられ、前記ピストンが前記通常位置と押し込み位置との間の前記液体流通管路を閉塞すると共に前記気体流通管路を連通する位置にある状態で、前記シール部材と他方の壁面との接触を解除することで前記気体流通管路を前記シリンダと前記ピストンの間を介し外部に開放するリーク手段と、を備えた。
Claims (4)
- 内視鏡に設けられた、気体流通管路と液体流通管路を含む複数の管路が接続されるシリンダと、このシリンダに進退自在に嵌挿されたピストンとを有してなり、前記複数の管路の連通状態を切り換える内視鏡用管路切換装置において、
前記ピストンが通常状態にある場合に、前記気体流通管路と外部とを隔離するために前記シリンダと前記ピストンのいずれか一方に設けられ、前記シリンダと前記ピストンのいずれか他方の壁面に弾性的に接触するシール部材と、
前記他方の壁面に設けられ、前記ピストンが押し込まれた状態を解除する動作の途中において、前記液体流通管路を閉塞させた後、シール部材と他方の壁面との接触を解除することで前記気体流通管路を外部に開放するリーク手段と、
を備えたことを特徴とする内視鏡用管路切換装置。 - 前記リーク手段は、前記他方の壁面に設けられた溝であることを特徴とする請求項1に記載された内視鏡用管路切換装置。
- 前記ピストンは、気体流通管路と外部を連通させる開閉可能な開口を有することを特徴とする請求項1に記載された内視鏡用管路切換装置。
- 前記ピストンは押し込まれることにより液体流通管路を連通させることを特徴とする請求項1に記載された内視鏡用管路切換装置。
