Claims (8)
- フラッシュシリンジアセンブリであって、
流体を保持するチャンバを画定する内面および外面を有する側壁と、開いた基端端部と、前記チャンバと流体連通する開口を有する末端壁であって前記末端壁を該開口が通っている末端壁を含む末端端部とを含む筒と、
前記筒内に配置された細長いプランジャーロッドであって、スライド可能に位置決めされた、前記筒の前記内面と流体密封接触するストッパを含む末端端部を備え、そのために、前記ストッパの前記筒に対しての末端移動によって前記筒から流体を押し出す、細長いプランジャーロッドと、
基端面およびそこから末端に延びる側壁を有するバルブであって、前記バルブの前記末端端部の中心部分は突起を有するバルブと、
を備え、前記バルブの前記基端面は、前記バルブが前記開口内に配置された際に前記チャンバと前記開口との間の流通連通を可能にする複数の開口部を含み、前記複数の開口部は、前記突起の長さに沿って一連のチャネルとして延びており、
前記フラッシュシリンジアセンブリは、
前記チャンバと流体連通する通路を備えるキャップであって、該キャップを該通路が通
っており、血管アクセス装置(VAD)と解放可能に接続可能な、末端端部上のルアーコ
ネクター、および前記筒に解放可能に取り付け可能な基端端部を含むキャップをさらに含み、
前記バルブの中心からバルブステムが末端方向に延びており、該バルブステムは基端直径および該基端直径よりも大きい末端直径を有しており、
前記キャップは、前記バルブステムに対して全面的な接触にあるときに流体漏れのない密封を形成するバルブシートを備え、
前記ストッパに末端に向かう力が加えられたときに、前記バルブステムは前記バルブシートと全面的には接触しない位置となり、前記ストッパに基端に向かう力が加えられたときまたは力が加えられないときに、前記バルブステムは前記バルブシートと全面的に接触する位置となり、前記チャンバから前記複数の開口部を通って前記筒の外に流出する流体の通り道を塞ぐことによって前記チャンバを前記VADから分離する流体漏れのない密封を形成する、フラッシュシリンジアセンブリ。 - 請求項1に記載のフラッシュシリンジアセンブリにおいて、前記複数の開口部は、前記バルブの前記基端面に六角形形状を有し、および、前記一連のチャネルは、前記一連のチャネルの長さに沿って円形形状を有する、
フラッシュシリンジアセンブリ。 - 請求項1に記載のフラッシュシリンジアセンブリにおいて、前記キャップと前記筒の前記末端壁との間の、前記筒の前記末端端部に配置されたガスケットをさらに備える、フラッシュシリンジアセンブリ。
- 請求項1に記載のフラッシュシリンジアセンブリにおいて、前記筒と同軸であり、末端端部および基端端部、および、内面および外面を有するスリーブをさらに備える、フラッシュシリンジアセンブリ。
- 請求項4に記載のフラッシュシリンジアセンブリにおいて、
前記スリーブの前記末端端部に接続されており、末端面および前記キャップの前記末端端部に隣接する基端面を有するハブと、
をさらに備える、フラッシュシリンジアセンブリ。 - 請求項5に記載のフラッシュシリンジアセンブリにおいて、前記ハブの前記末端面と接触する殺菌剤を含む殺菌システムをさらに備える、フラッシュシリンジアセンブリ。
- 請求項6に記載のフラッシュシリンジアセンブリにおいて、前記スリーブは、前記ハブの前記基端面が前記キャップの前記末端端部を末端側から見えない状態にする末端位置から、前記スリーブの基端移動の際に前記殺菌システムが前記キャップの前記末端端部との接触によって前記スリーブから離脱される基端位置へスライドするように構成されている、フラッシュシリンジアセンブリ。
- 請求項1に記載のフラッシュシリンジアセンブリにおいて、前記突起は、円錐台形状をしている、フラッシュシリンジアセンブリ。
