Description
ニードル内に配置してこのニードルに対してニードル長さに沿って移動することができる内側細長部材と、
前記内側細長部材を前記ニードルに対して前方に押圧し、使用前には内側細長部材の前方端部がニードルの前記先端よりも前方に位置するが、首の組織を通過する間は首の組織に掛合することによりニードルの前記先端よりも後方に位置し、気管に貫入したときニードルに対して前方に移動させる弾性部材と、
前記ニードルの後方端部側に設けた視覚的インジケータであって、内側細長部材のニードルに対する位置に応じて表示が変化し、気管に貫入したことをユーザーが視覚で知ることができるようにした視覚的インジケータと
を具え、さらに、前記ニードルの外側に沿って延在する気管開口用チューブを設け、気管貫入後にニードルを取り外して気管開口用チューブを気管に残すことができるようにしたことを特徴とする。
器具の初期的使用状況は、図1及び図2の器具と同様にし、通常輪状甲状領域で気管にアクセスする。挿入中、赤色のフラッグ116が窓に見え、緑色のフラッグ117が見えるようになったとき気管まで貫入した状態となる。

Claims (8)
- 気管を介して肺通気を行う医療外科器具であって、首の組織を経て気管に貫入する鋭利な先端(12,112)を有する中空のニードル(10,110)を具える医療外科器具において、
ニードル(10,110)内に配置してこのニードルに対してニードル長さに沿って移動することができる内側細長部材(13,113)と、
前記内側細長部材(13,113)を前記ニードルに対して前方に押圧し、使用前には内側細長部材の前方端部(14,114)がニードルの前記先端(12,112)よりも前方に位置するが、首の組織を通過する間は首の組織に掛合することによりニードルの前記先端(12,112)よりも後方に位置し、気管に貫入したときニードル(10,110)に対して前方に移動させる弾性部材(18,118)と、
前記ニードルの後方端部側に設けた視覚的インジケータ(16,17)であって、内側細長部材(13,113)のニードルに対する位置に応じて表示が変化し、気管に貫入したことをユーザーが視覚で知ることができるようにした視覚的インジケータ(16,1724;116,117,124)と
を具え、さらに、前記ニードル(10)の外側に沿って延在する気管開口用チューブ(30)を設け、気管貫入後にニードルを取り外して気管開口用チューブ(30)を気管に残すことができるようにしたことを特徴とする医療外科器具。 - 前記器具に、ニードル(10)に取り付けた患者側のテーパ付き端部(21)を有する拡張器(2)を設け、前記気管開口用チューブ(30)を前記拡張器(2)の外側に取り付け、拡張器の前記テーパ付き端部が前記気管開口用チューブの患者側端部(34)から突出するようにした請求項1記載の医療外科器具。
- 前記内側細長部材(13,113)を中空とし、この部材に沿ってガス通路をなすようにした請求項1または2に記載の医療外科器具。
