| description | PROBLEM TO BE SOLVED: To make a generally used blood drawing needle provide with a hub having an external thread part easily attachable and detachable, to make only the blood drawing tube removable without touching the blood drawing needle with the hand at the time of removing the blood drawing needle and to prevent the disengagement of the blood drawing needle during blood drawing. SOLUTION: An elastic holding member 3 is arranged on the outer side of the end face 2a of a cylindrical body 2 into which the vacuum blood drawing tube of the blood drawing tube holder is inserted. The member 3 is composed of a cylindrical member which has a notch 3a extending approximately parallel to an axial direction and is provided with a projecting part 3b fittable to the thread grooves of the blood drawing needle in its inner peripheral surface. In such a case, the width of the notch 3a of the elastic holding member 3 is expanded to expand the diameter of the member 3, by which the insertion of the blood drawing needle is made possible. The elastic holding of the blood drawing needle by the member 3 is made possible by the elastic restitutive force of the member 3. The easy removal of the blood drawing needle is made possible by expanding the diameter of the member 3 after blood drawing. |
