Description
本開示は、一般に、静脈内カテーテル(例えば、血管アクセス装置)に関する。より具体的には、本出願は、バネ駆動の針安全性を備えたカテーテルおよび針アセンブリのさまざまな使用方法およびシステムを開示している。一般に、血管アクセス装置は、診断または治療上の理由から、末梢血管または中心血管を介して静脈に挿入される。血管アクセス装置は、患者への液体(生理食塩水、血液、医薬品、および/または完全非経口栄養)の注入、患者からの液体(血液など)の回収、および/または患者の血管系のさまざまなパラメータの監視に使用できる。さらに、この開示では、医療従事者に最も近い装置の部分に言及するために用語「基端」を使用し、患者に向かうまたは医療従事者から離れた装置の部分に言及するために用語「末端」を使用する慣例に従う。
本開示は、概して、引き込み可能な針を備えたカテーテルおよび針アセンブリに関する。より具体的には、本開示は、偶発的な針刺しを防止する格納式針を備えたカテーテルおよび針アセンブリについて説明する。これらのカテーテルおよび針アセンブリを使用する方法も説明する。
開示された実施形態の上記および他の特徴および利点が得られ、容易に理解されるように、上記で簡単に説明したシステムおよび方法のより具体的な説明は、その特定の実施形態を参照することにより提供され、それらは添付の図面に示されている。これらの図面は典型的な実施形態のみを示しており、したがってその範囲を限定すると見なされるべきではないことを理解する。開示されたシステムおよび方法の例示的な実施形態は、添付の図面を使用することにより、以下で追加の特徴および詳細とともに詳述され実証される。
以下の説明は、説明されたカテーテルおよび針アセンブリの完全な理解を提供するために特定の詳細を提供する。それにも関わらず、当業者は、これらの特定の詳細を使用することなく、説明されたカテーテルおよび針アセンブリ、およびそれらを作成および使用する方法を実装および使用できることを理解するであろう。実際、カテーテルおよび針アセンブリは、図示された装置と方法を修正することで実用化でき、業界で従来使用されている他の装置と技術と組み合わせて使用できる。
