Abstract
【解決手段】医用注射針をさやに収める安全装置であって、安全装置は、鋭利な針先を持ち医用注射針を形成するカニューレ(34,40)と、ハブにヒンジ的に結合した成形部品とを備える。該部品は長いさや(140)を備え、さやは直列に連結された複数の部分(150,160,170)からなる。各部分(150,160,170)は少なくとも1つの隣接した部分と一体の成形されたヒンジ(152,162,172)で連結されている。少なくとも1つの部分は開放したオリフィスを有し、カニューレはオリフィスの中を通りカニューレの周りに交差の軸を形成する。さやが直線的に伸長したときカニューレが中に入るチャンネル(220)を備える。さやは、カニューレをさやに対し捕らえしっかりと固定する少なくも1つのラッチ部材(210,212)を有する。さやとカニューレは、鋭利な針先を閉じ込め保護し針先への接触を不可能にする剛体を形成する。
【選択図】図7−1
Description
医用注射針装置の他の部品(例えば、しゃ血バレルや医用注射針ハブ)と共に一体として成形できる安全さやを提供することが他の目的である。
バレルならびに注射針アセンブリー及び安全シュラウドからなり、一体で、独立した、安全な装置で、全体が2つの射出成形で作られた部品のみを要する装置を提供することは重要な目的である。
前述した目的や他の目的並びに本発明の特徴は、以下の図面を参照した詳しい説明から明らかになるであろう。
Cは図7で示した安全さやの模式図で、さやが、注射針を使用する状態から注射針を閉じ込める状態に動いていくときのさやの相対位置を示す。
