Abstract
Description
安全IVカテーテルは、先行技術に記載されている。
欧州公開EP1785159A1(D1)は、カテーテル装置およびハウジング内に収容されたセプタムを通過するニードルを備えたカテーテル装置に関し、セプタムはハウジングを封止するように設計される。D1はさらに、ハウジングからニードルを取り出す際、ニードルを保持するニードルシールドを備えたカテーテル装置を開示する。ニードルがハウジングから取り出された場合、ニードルシールドは、セプタムから外れて、ニードルシールドは分離できる。
ドイツ公開DE4434569A1は、ニードルを含み、ニードルシャフト上にスライド可能に配置されたニードル先端プロテクタを備えたカテーテル装置に関する。ニードル先端プロテクタまたはニードルガードは、中空本体およびシールを有し、ニードル先端プロテクタの接続部に受け入れられる。シールを含む先端プロテクタは、カテーテルハブに取り外し可能に装着され、カテーテルハブからの血液の流れを一時的に制限する。
