Claims (14)
- 患者の人工気道に呼吸デバイスを接続するためのアダプタアセンブリであって、
換気用ポート、呼吸器官用ポート、およびアクセス用ポートを形成して相互に流体接続し、アクセス用ポートと流体接続して該アクセス用ポートから延びる通路を形成する導管部を備えるマニホールドと、
通路を選択的に閉塞し、弁体と弁支持構造体とを備える弁アセンブリとを有し、
弁体は、対向し合う第1および第2の端と内部チャンバーとを備え、且つ、
前面および後面を備えてその前面が弁体の第1の端を定義する環状のベース部と、ベース部の後面から延びて第2の端で終端するドーム形状の壁部とを備え、スリットが第2の端でチャンバーが開くように壁部に貫通形成され、壁部がスリットの対向し合うシール面を定義し、
弁支持構造体は、
導管部に沿って形成されてベース部を封密に保持し、且つ、ベース部の前面と係合する環状の上側面と、ベース部の後面と係合する環状の下側面とを備え、上側面または下側面の少なくとも一方に隆起部が形成され、
最終組み立て状態において、弁体が通路を横断するように配置されるとともにスリットが弁アセンブリを通過する選択的に開閉可能な経路を形成し、隆起部からの力によって、ベース部が変形するとともに対向し合うシール面が付勢されて接触するアダプタアセンブリ。 - 弁支持構造体が、ベース部から第2の端に向かってスリット面と平行な方向に、弁体の壁部を押圧して付勢する、請求項1に記載のアダプタアセンブリ。
- 最終組み立て状態において、隆起部が、スリット面からオフセットされている、請求項1に記載のアダプタアセンブリ。
- 環状の下側面が、周方向に間隔をあけて設けられた第1および第2の隆起部を備えるリブを有し、
ベース部が、これらの隆起部と接触する領域で大きく変形する、請求項1に記載のアダプタアセンブリ。 - 環状の上側面が、周方向に間隔をあけて設けられた第1および第2の隆起部を備えるショルダー部を有し、
ベース部が、環状の上側面の隆起部と接触する領域で大きく変形する、請求項4に記載のアダプタアセンブリ。 - 最終組み立て状態において、下側面の隆起部が、上側面の隆起部に対して長手方向に位置合わせされている、請求項5に記載のアダプタアセンブリ。
- 壁部が、ベース部から延びる第1の部分と、第1の部分から第2の端まで延びる第2の部分とを備え、
スリットの領域における壁部の厚さが、第1の部分の壁部の厚さに比べて厚くされている、請求項1に記載のアダプタアセンブリ。 - 弁体が、ベース部の前面から突出するフィンガー部を備え、
最終組み立て状態において、フィンガー部が、隆起部に対して長手方向に位置合わせされる、請求項1に記載のアダプタアセンブリ。 - 弁体のスリットが、ベース部の中央に位置し、且つ直線状である、請求項1に記載のアダプタアセンブリ。
- 弁体が、スリット面に対して垂直方向に延びる少なくとも1つのフィンガー部を備える、請求項1に記載のアダプタアセンブリ。
- スリットが、壁部の第2の端を2つの片割れに分割し、
それぞれの片割れに、対向し合うシール面の一つが形成されている、請求項1に記載のアダプタアセンブリ。 - 弁支持構造体が、マニホールドのハウジングによって形成されている、請求項1に記載のアダプタアセンブリ。
- 弁支持構造体の環状の上側面および下側面が、マニホールドの別々の部品によって形成されている、請求項1に記載のアダプタアセンブリ。
- 最終組み立て状態において、ベース部が、壁部の外側表面に作用する非対称な付勢力によって変形する、請求項1に記載のアダプタアセンブリ。
