Abstract
【解決手段】シリンジ口14が設けられた筒体11と、押部12cに通気孔VAが形成され、軸部12bに通気孔VAから内部を通り先端部まで貫通する通気路16が形成されたピストン体12と、押したピストン体12を元の位置へ復帰させるバネ17とから構成される。上記押部12cをその通気孔VAを塞ぎながら親指等で押し、ピストン体12を往動さると、シリンジ口14から送気が行われ、その後に親指等を離すと、筒体内へ通気孔VA及び通気路16を介して空気が流入し、バネ17によってピストン体12は元の位置へ自動的に復帰する。従って、押部12cの繰返しの押し操作により、連続した送気が可能となり、内視鏡装置では、送水、送気を実行することができる。

Description
請求項2の発明は、内視鏡の送気又は送水ポートに上記シリンジ口を管接続し、請求項1記載の自動復帰式シリンジを内視鏡用として用いることを特徴とする。
また、内視鏡用自動復帰式シリンジによれば、送気/送水に関する機器の携帯化、簡易化、ひいては内視鏡装置の携帯化、簡易化が可能となり、設備の整った施設以外の各種場所、ベッドサイド、緊急時等における内視鏡の使用が容易となり、利便性の高い内視鏡装置が得られるという効果がある。
