る。When the protector 5 is moved toward the distal end of the needle tube, the fourth
As shown in FIGS. 3A and 3B, the blades 2b are retracted into the blade retraction slits 5b, 5b, and the hub 2 and the needle tube 1 are connected to each other with the base end of the hub 2 as a retraction end. It is drawn into the inside of the protector through the needle tube drawing opening 5a.
The product is provided in this condition. As shown in FIGS. 3 (a) and 3 (b), in order to pull out the needle tube and the hub 2 from the protector 5 and use the same, the protruding ends of the blades 2b, 2b are grasped and the blades are moved toward the tip of the needle tube. It moves until it comes off from the retraction slits 5b, 5b. At this time, the wings 2b, 2b are twisted so that the tip of the needle tube is lifted. Then, the tip of the needle tube 1 first protrudes from the needle tube retraction opening 5a, and as the blades 2b, 2b move, the needle tube 1 protrudes greatly into the bevel. After the wings 2b, 2b are removed from the wing retraction slits 5b, 5b, the protector 5 can be used by moving the protector 5 away from the hub 2 by a required length. After use, it is disposed as shown in FIGS. 4 (a) and 4 (b) and then discarded. In this case, the needle tube drawing opening 5a and the blade drawing slits 5b, 5b are closed with an adhesive tape and then discarded.
