An existing filter syringe does not penetrate into the filter inner channel during the filtering and injection of a single needle, and a glass fragment remaining between the needle and the filter passes through the needle during the injection process A filter needle with a rotating incision removal type inhalation tube which improves the shortness to flow into the human body, and a filter syringe using it are introduced.Solution: the needle part is provided with a suction tube which is slightly larger than the needle, and the suction part formed so as to be able to be incixed in the spiral is put into the needle part, and after the connecting pipe inside the suction part which has been stabbed in the inflow hole is removed from the needle part, the needle part is removed An inflow hole connected to the filter is closed by interlocking the rotary plate stopper of the rotary plate to open the outlet hole connected to the needle.With the above described concise and elaborate operation of the soft part, the needle maintains the state of the outflow pipe, not one-way conduit, even after the suction is completed. Therefore, it is possible to confirm the presence or absence of the blood detection after it is inserted into the human body, and it is possible to confirm the existence of the blood detection, and this filter is completely isolated from the needle, and the human body re injection prevention of the filtering material compared with the existing filter syringe. It is very excellent in stopping effect.【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
