Abstract
【解決手段】穿孔部材22と、ハウジング44と、穿孔部材に対して横方向の軸線で配向され、空隙を画定する板を含むクリップ28とを備える。板の空隙が穿孔部材の縦軸に対して回転可能であり、空隙を画定する板の表面が穿孔部材と係合してその滑動運動を防止する。クリップが近位部分および遠位部分を有する第1脚部を含み、遠位部分が医療器具38と係合する空隙を画定する。クリップはまた、近位部分及び遠位部分を有する第2脚部を含み、第2脚部の遠位部分が穿孔部材と係合する支承表面を含む。脚部が、収束方向に運動するように弾力的にバイアス付与され、従って第1空隙が結合方向に配置され、第1脚部の遠位部分が医療器具を係合解除する。

Description
い。安全シールドは、針を使用する様々な器具で使用できることが最も望ましい。安全シールドは容易かつ効率的に製造され、組み立てられる。本開示は、当技術分野で経験された関連の短所および欠点を克服する。
被験者から外し、穿孔部材を外した後、受動的保護を提供するように構成することが有利である。
リアランス開口35も含む。結合方向では、遠位端26はクリアランス開口35と長手方向に整列する。クリアランス開口35は、遠位部分36と遠位端26との係合を防止する。遠位部分36はクリアランス開口35を含まないことが想定される。
1脚部332の留め具333と着脱式に係合し、クリップ28を滑動方向に維持する。上記と同様のクリップ28の結合方向では、脚部332、340は収束運動するようにバイアス付与され、したがって脚部332は横方向および下方向に動作する。第2脚部340の遠位部分はこれによって解放され、留め具333から係合解除されて、第1脚部332および窓330の結合方向への回転を促進する。フック部分370は、自身に取り付けられた医療器具を解放する。
ル38は安全シールド20から分離可能になり、針カニューレ22がクリップ28およびハウジング44によって保護状態で捕捉される。安全シールド20を廃棄することができる。
方向で、針カニューレ422は窓434、434Aを通り抜け、遠位部分436は脚部432の膨張のせいで、横方向に自由に動作する。フック部分470は、同様に横方向に動作して、医療器具を解放し、これはハウジング44から分離可能になる。
向では、針カニューレ22は窓634を通り抜け、遠位部分636は脚部632、640の偏倚力により横方向に自由に動作する。フック部分670は、同様に横方向に動作して、フランジ72を解放する。これで、カテーテル38はハウジング644から分離可能になる。
