Description
が所定の位置に置かれた際に上部食道括約筋の上端に位置するようにマスクの遠位端に位置する端部を有する小径のドレナージチューブが通常は組み込まれており、チューブは、患者の口から外に延在するのに十分な長さを有し、上部食道括約筋から胃排出物を能動的または受動的に取り除くことができる。代替的な提案によれば、ドレナージチューブは、マスクの遠位端を越えて食道自体の中に延在してもよい(米国特許第4,995,388号、図7および図11)。
胃排液チューブへの通路となるアトリウムを含む。理解されるように、アトリウムは、物の逆流または嘔吐が起こった場合にマスクが外れてしまうリスクを実質的に減らす可能性のある拡大された空間または導管を提供し、気道の完全性が維持され、これにより、胃への空気混入のリスクを最小限に抑える可能性がある。
く拡張可能な容量を有する導管が提供される。
法であることがわかる。機能の実行が求められるまでは生体構造内に占める空間を最小化するように胃排液チューブを拡張可能な材料から形成することは、有利である。なぜなら、装置の挿入が容易となり、装置が適所にある場合、特に装置が長期にわたって適所に残される場合において、繊細な生体構造に対する外傷が小さくなるからである。胃排液チューブを構成する柔らかい材料からアトリウム8が形成されるようにこれらの特徴が組み合わされると、さらなる利点が得られる。なぜなら、マスクは、挿入時の外傷を避けるために十分に柔らかく、嘔吐時の圧力によって拡張できるような大きな容積のアトリウム8を提供することができるからである。このような拡張により、マスクが原位置にある場合において喉の後壁部に対してばねのように作用するドーム(図4)のように外皮5bの前面側が変形し、喉頭に対してカフ6が押し込まれ、装置の封止した状態の維持が補助される。
を有する装置において最も重要なことは、胃内容物の流れが妨げられず、上部食道括約筋の周りに形成された封止が破壊されないことであることが分かった。この構成は、この目的を達成するために生体構造内の空間を最も良好に利用する構成である。同様に、従来の装置の簡易な一体の断面を有する導管とは対照的にアトリウム8を設けて胃液流を受けることにより、実際は上部食道括約筋に対する中空の漏れ止めプラグであるマスクの上に低流量かつ高容量の逃げ道が設けられる。本発明のこの実施形態の装置1は、合流する液体のための十分に容量の大きい逃げ経路を提供しながら、ユーザがこのようなプラグを適所に置き、保持することができる。さらに、記載されたように後方に傾斜した胃入口ポートを設けることによって、大きな荷重を受けた場合、特にアトリウムがすぐ上流に設けられた場合において、上部食道括約筋のまわりの封止を無傷のままとなるように補助されることがわかった。
Claims (10)
- 患者の肺換気を容易にするための人工気道装置であって、1つの気道チューブと、1つの胃排液チューブと、前記気道チューブの一端に設けられるマスクとを備え、マスクは、バックプレートを含み、喉頭口の外周の周りに封止を形成することが可能な周囲構造を有し、周囲構造は、マスクの中空内部空間または内腔とマスクの内腔に開放される気道チューブとを囲い、マスクは、食道を離れる胃内容物の排液チューブへの通路となるアトリウムを含み、該アトリウムは、バックプレートによって規定され、規定する部品は、前記バックプレートの壁部であり、前記気道チューブは、前記胃排液チューブの外壁に包囲された空間の内側に取り付けられる、人工気道装置。
- 壁部は外皮と内皮とを含む、請求項1に記載の人工気道装置。
