Claims

[Claims for Utility Model Registration] 1. The needle holder 7 of the injection needle 3 is removed from the tapered nozzle 4 for fitting and fixing the injection needle taper provided on the tip wall 2a of the injection barrel 2 of the syringe 1, and the removed injection needle 3 is accommodated in the needle accommodation space X, and the needle extraction unit 13 includes a needle extraction unit 13 with an operating tool for pressing and fixing the needle holder 7 on the injection needle extraction stand 12;
Two extracting means 13 and 14 are provided, including a self-boosting type syringe needle extracting means 14, and one of the operating tool boosting type syringe needle extracting means 1 is provided.
3 is an operating tool 1 supported on a syringe needle extraction stand 12;
7, the pressing tool 18 is configured to be driven with a boost force, and a syringe needle mounting portion 20 is provided on the syringe needle extraction stand 12 facing the syringe needle storage space X, and the operating tool 17 and the pressing tool 18 are unclamped. An unclamping spring 24 for returning the needle to the side is interposed from the fixed side of the needle extraction stand 12 to the operating tool 17 via the pressing tool 18, and the other self-powering needle extraction means 1
4 is configured to apply a withdrawal force in the axial direction of the injection needle 3 that is increased by a lever ratio approximately corresponding to the barrel length and diameter of the syringe barrel 2, and a needle extraction groove 32 is provided in the needle extraction stand 12.
The injection needle removal groove 32 faces the injection needle accommodation space In the fitted state, the tip wall 2a of the syringe barrel 2
and the holder flange 7a of the injection needle 3 can be received by the inner circumferential wall 35 of the injection needle removal groove 32. 2. The injection needle placement part 20 is formed on the upper wall 12a of the injection needle extraction table 12, and the operation tool 17 is formed into a long lever, and the pressing tool 18 is integrally formed on the lower surface side at a mid-length position. The proximal end 17a of the elongated lever-like operating tool 17 is pivoted to the syringe needle extracting stand 12 so as to be able to move up and down, and the elongated lever-like operating tool 17 and the syringe needle extracting stand 12 are used for unclamping. The syringe needle extractor according to claim 1, further comprising a spring (24).
