Abstract
Description
胃腸管へのアクセスすることを目する装置に関する。
有の設備を有する喉頭マスク気道装置が開発されてきた。これらの装置は、一般に、小径の排液チューブを組み込み、排液チューブは、マスクが定位置にあるときに上部食道括約筋の上端部に寄りかかるようにマスクの遠位端に配置された端部を有し、このチューブは、胃の排出物を上部食道括約筋から能動的または受動的に除去することを可能にするために、患者の口から外に延びるのに十分な長さである。代替提案によれば、排液チューブは、マスクの遠位端を超えて食道自体の内部へと延びることができる(米国特許第4,995,388号、図7および図11)。
とができる。管を通って流れる流体は、管内の狭窄があるところで速度を増す。流れる液体は圧力を有し、移動する液体の全エネルギーは同じままとなるはずであるので、図1に示すように、速度の増加は同等の圧力低下を生み出すはずである。
された、以前の喉頭マスク気道装置試作品は、食道から生じる逆流する流体を受容するためのチャネルを提供しており、その中でチャネルの直径は、図4に図示するようにほぼ一定であり、上部食道括約筋と呼ばれる構造の狭窄領域の直径と同等である。
しのけられる危険性を潜在的にかなり低減させ、気道の完全性が維持されることを可能にし、胃の吸入を潜在的に大幅に最小限に抑え、さらに、潜在的にいかなる嘔吐物も食道から効果的に放出されることを可能にし、嘔吐時に食道が破裂する危険性を最低限に抑える。
マスクは、入口を画成することができ、その入口は、折りたたみ可能なリングまたはU字形構成を備える。
の半分のヒンジ機構により、図示の形状を実現する。
で、マスク3の挿入を促進する第1の(膨張されない)状態から第2の(膨張させられた)状態へと動かすことができ、マスク3が定位置にないときに存在する咽頭空間の近似構造を再構築する。
た胃カメラまたは同様のもののケーブルを受けることができ、レールとしてのケーブルに沿ってマスクを摺動させることにより患者の咽頭内へのマスク3の誘導を容易にする。
にくると、直径が大きい胃のチューブを提供することが可能になるが、同時に、挿入時にマスクは、胃の排液チューブの入口が効果的に閉じる非膨張状態になることが意図されるので、患者内へのマスクの挿入が容易になる。
第7の実施形態と同様、第8の実施形態は、マスク部分の内部へと開く2つの気道チューブ73、74を備え、このマスク部分は、膨張可能なカフ76によって取り囲まれる。気道チューブ73、74は、装置78の近位端にて分岐部分77にてつながれて、単一の気道連結具79をもたらす。
9内へと延び、その一方の端部が開口87と整列し、他方の端部は、気道チューブ83が管部分89および開口87を通じてマスクの本体85の内側と気体連通するように、気道チューブ83の遠位端を受ける。気道チューブ82は、図58に示すように、その背側上に平坦な面を備え、かつ、実質的に五角形の断面を有する気道チャネルまたは内腔を備え、そのうちの1つの面が湾曲する。気道チューブは、溶接または接着などなんらかの適当な手段によって、管部分89内へと気密に連結される。開口87自体は、ウェブ内に形成された2つの可撓性のバー90、91を備え、これらのバー90、91は、開口を横切って伸び、患者の喉頭蓋が開口内へと落ちる事を防ぐように作用し、したがってマスク39が定位置にあるときに気道を遮断する。
