Title: 回転切開除去式吸入管が備えられたフィルタニードルおよびフィルタ注射器
IPC: A61M5/31
Filed: 2016-05-04
Abstract: 【課題】既存のフィルタ注射器が一つのニードルでフィルタリング吸入と注射液排出を遂行する過程でフィルタ内側流路まで深く流入せず、ニードルとフィルタとの間に残留したガラス破片が注射過程でニードルを通して人体に流入する短所を改善した、回転切開除去式吸入管が結合されたフィルタニードルと、それを用いたフィルタ注射器が紹介される。 【解決手段】ニードルより若干大きな吸入管を備え、螺旋状に切開され得るように形成された吸入部をニードル部に被せた後、回して取り外す過程で流入孔に刺されていた吸入部内側の連結管が抜け出しながらニードル部の回転板栓を連動させてフィルタに連結された流入孔を塞ぎ、ニードルに連結された流出孔を開放する。軟質部品の前記の簡潔かつ精巧な作動により、ニードルは、吸入完了後にも一方向管路ではなく双方向に開いた流出管の状態を維持する。従って、人体に挿入後、軽く吸い上げて血液検出の有無を確認でき、この時にもフィルタでこされたガラス破片などはニードルと完全に隔離され、既存のフィルタ注射器に比べてフィルタリングされた物質の人体再注入防止効果に非常に優れている。
