Description
本出願は、2018年4月10日に出願された“Protector Housing Plastic Spike with Flash Intended for DVO Last Drop Extraction”というタイトルの米国特許仮出願第62/655,427号に対する優先権を主張し、該特許の開示全体は、その全体の参照によって本願明細書に組み込まれるものとする。
本発明は、クローズドシステム移送装置に使用されるスパイクに関し、該スパイクは、流体開口部を覆って、最後の一滴の引出しを容易にし、およびコアリングを減らすプレカットフラッシュを含む。
医療用の医薬品や溶剤は、多くの場合、ゴム、プラスチックまたはエラストマー栓、栓、膜または穿刺可能なキャップによってシールされているバイアル、瓶またはバッグ等のガラスまたはプラスチック製の容器内に供給される。このようなシール部材は、該医薬品の劣化または汚染を防止し、シェイクすることによって容器の内容物が混合されることを可能にし、および該容器の該内容物が漏出することや周囲を汚染することを防ぐ。流路および該流路と連通する開口部を備えているカニューレまたは中空スパイクは、一般的に、流体を該容器に供給して、そこから流体を引き出すようなシール部材を介して挿入される。
本願明細書における以下の説明のために、「端部」、「上方」、「下方」、「右」、「左」、「垂直方向」、「水平方向」、「上部」、「底部」、「横方向」、「長手方向」およびこれらの派生語等の用語は、図面において特定の方向に向けられているように本発明に関連するものとする。しかし、本発明は、明確に記述されていない限り、さまざまな代替的な変形例および工程の順序を想定することができることを理解すべきである。また、添付図面に図示されている、および以下の明細書に記載されている特定の装置およびプロセスは、本発明の単に例示的な実施形態であることも理解すべきである。したがって、本願明細書に開示された該実施形態に関連する具体的な寸法および他の物理的特性は、限定的であると見なすべきではない。さらに、本発明は、明確に記述されていない限り、さまざまな代替的な変形例および工程の順序を想定することができることを理解すべきである。
Claims (20)
- 流体容器から外部に流体を移送する装置であって、
前記流体容器のシール部材を貫通させるための遠位端と近位端を有し、および流体流通のための長手方向の流路を画定し、第一の開口部がその該遠位端に配置され、該第一の開口部が該長手方向の流路に流体的に連通している穿刺部材と、
前記第一の開口部を覆って配置されたカバーとを備え、
前記カバーは、第一の部分と第二の部分とに分ける前記カバーの中心部に沿った切れ目にプレカットパターンを有し、
