Description
って、バルブの外面と孔付きカテーテルアダプターの内面との間にギャップをもたらす。サイドポートからの液体は、このギャップを通って、孔付きカテーテルアダプターの基端チャンバーの中へ流入する。注入に続いて、バルブの本体部は、その初期構造を再び取り、それによって、サイドポートの通路に対する流体密封シールを再確立する。
本発明の上述の特徴および利点ならびに他の特徴および利点が得られる様式がより容易に理解されることとなるために、上記に簡潔に説明されている本発明のより特別な説明が、添付の図面に図示されているその特定の実施例を参照して行われよう。これらの図面は、本発明の典型的な実施例だけを示しており、したがって、本発明の範囲を限定するように考慮されるべきではない。
プター20の基端部22の中へ流体を挿入することによって、開けられた位置に一時的に付勢され得る。スリットからバルブアクチュエーターを取り外したとき、即ち、流体圧力が管腔26内で減少するとき、膜の弾性により、スリットが閉じることを引き起こし、それによって、再度、管腔26を通る液体の通過を妨げる。
き出され、カテーテル12は、患者内に放置される。
は、溝部72の内径は、バルブ40の外径よりもわずかに小さくなっており、それによって、溝部72内にバルブ40の締まりばめをもたらす。他の場合では、バルブ40は、接着剤またはエポキシ材料を介して、溝部72の中に保持される。
それによって、管腔26およびバルブアクチュエーター90を通過する流体に関する多様なフローパターンをもたらす。したがって、バルブアクチュエーター90の中空の内部の中の液体は、1以上のウィンドウ97を通過し、管腔26の中へ至ることが可能である。
02にスライドさせ、それによって、図2Aに示されているように、スリット46の流体密封シールを取り戻す。
がある。したがって、いくつかの実施例では、保持クリップ98の最大限許容される末端方向の移動が、先端部94がスリット46の中に過大挿入されることを防止するように、基端溝部79の幅は選択されている。
よりも小さい断面積を含む。
々の通気孔チャネルのそれぞれの間に流体連通をもたらす。
Claims (2)
- 孔付きカテーテルアダプターを使用するための血液制御バルブであって、
基端開口部と、末端膜と、それらの間に延在する内側の空洞とを有する可撓性のチューブと、
孔付きカテーテルアダプターの内径にほぼ等しい直径を有する外面とを含み、
それによって、前記バルブは、摩擦ばめを介して前記カテーテルアダプターの中に保持されるように構成され、前記外面は、前記カテーテルアダプターの管腔と前記孔付きカテーテルアダプターのサイドポートの通路との間にシールを形成するために十分な長さをさらに有しており、
それによって、前記外面は、前記サイドポートと前記管腔との間の流体連通を防止し、
前記末端膜は、前記管腔の中に締まりばめされる場合、前記孔付きカテーテルアダプターの前記管腔を、基端チャンバーおよび末端チャンバーに分割し、
前記バルブは、前記バルブを迂回する空気のための通路をもたらすように、前記外面に凹んだチャネルまたは溝部を形成する第1の通気孔を含み、
前記バルブの前記外面は、前記第1の通気孔に流体連通している環状の通気孔リングであって、該環状の通気孔リングを介して、前記第1の通気孔と前記バルブの前記内側の空洞との間で流体連通させるための第2の通気孔を含む環状の通気孔リングをさらに含む血液制御バルブ。 - 前記シールは、前記サイドポートを介し流体を注入することによって選択的に破壊され得るものであり、それによって、前記流体が、一時的に前記サイドポートの前記通路を通って流れ、前記バルブの前記外面と前記カテーテルアダプターの内面との間に設けられる空間を介して、前記カテーテルアダプターの前記管腔の中に流入できる請求項1に記載のバルブ。
