PURPOSE:To surely fix a medical needle in one touch at the top edge opened port part of a holder by chucking a stepped part as engagement recessed part on the top edge side of a hub by a chuck hook as engagement projection and setting a stepped part formed on the hub and fitting the side surface of the hub onto a hub supporting wall. CONSTITUTION:A protecting case K is held, preventing the taking-out from the protecting case K, and the basic edge side part 1c of a needle pipe 1 covered with the rubber sheath 2 of a medical needle A is strongly pushed in so as to penetrate through the top opened port part of a holder B. Then, a pushing opening hook 23 installed onto the hub 2 of the medical needle A pushing-spreads a chuck hook 12 as engagement projection which is formed at the top edge of the flexible wall 11 of the top edge opened port part of the holder B. At the time point when the pushing opening hook 23 passes through the chuck hook 12 as engagement projection, the pushing opening hook 23 and the chuck hook 12 are close-attachment-engaged, and the medical needle A is prevented from being pulled out, and the stepped part 21 formed on the hub 2 of the medical needle A contacts the top edge opened port part of the holder B and stops. Thus, the medical needle A can be surely fixed. |
