By forming such a flat surface portion 4a, if the orientation of the blade surface of the puncture needle portion 2a is set in correspondence with the flat surface portion 4a, the blood sampling needle 5 is attached to the holder 10 using the flat surface portion 4a as a guide. Since it can be done, the mounting work becomes easier than the visual inspection of the blade surface. The protector shown in FIG. 5 has a flat surface portion 4a, and the orientation of the blade surface of the puncture needle portion 2a is made to correspond to this flat surface portion 4a.
It suffices that the orientation of the blade surface and the specific portion of the protector 4 can be associated with each other. For example, it is easier and preferable to form a portion having a specific shape, such as forming a convex portion or a concave portion extending in the axial direction on the outer surface of the protector 4, because the mounting work can be performed by tactile sensation. An instruction mark such as a line extending in the direction may be provided. Further, as shown in FIG. 4, ribs 4a extending in the axial direction are provided on the inner surface of the rear end portion of the protector 4.
Two ribs 4a are provided at opposite positions. The rib 4a may be one, or three or more. The rib 4a cooperates with the rib 3h of the hub 3 as described above to form a hub forced rotation mechanism.

ブの保持を解除して行ってもよい。As shown in FIG. 6, the lid member 8 has a hollow needle insertion portion 8e through which the small diameter portion 3a of the hub 3 is inserted.
Around the hollow needle insertion portion 8e, an abutting portion 8a that abuts the hollow needle portion side surface of the expanded diameter portion 3b of the hub 3 is formed.
Further, the contact portion 8a is provided with a hub rotation suppressing mechanism for suppressing rotation of the hub of the hub. Specifically, the hub rotation suppressing mechanism is configured by a concave portion or a convex portion 8b that engages with a convex portion or a concave portion 3c formed on the hollow needle portion side surface of the expanded diameter portion of the hub 3. Further, the concave portion or the convex portion 8b in this embodiment is a knurl (a concave-convex portion having a triangular cross section) formed in an annular shape. By forming the concave portion or the convex portion 8b in such a knurl (a concavo-convex portion continuous in an annular shape), it is possible to suppress the rotation of the hub while the orientation of the blade surface of the puncture needle portion 2a is set to an arbitrary position. it can. Since the engagement between the two is not strong, when the blade surface of the blood collection needle when attached to the holder is not in the desired orientation, the protector 4 is rotated so that the rib 4a of the protector 4 is attached to the hub 3. The hub 3 can be rotated by bringing it into contact with the rib 3h and applying a torque to the hub 3 that exceeds the suppressing force of the hub rotation suppressing mechanism.
The orientation of the blade surface can be finely adjusted. The fine adjustment of the direction of the blade surface may be performed by pressing the pressing portion and releasing the holding of the hub by the holder.
