Has a wing shape and is generally fixed by inserting a puncture needle into the wing of the wing shape. Figure 10
As shown in FIG. 2, in such a blood collection puncture needle 7, a cap-shaped case 3 made of a tubular body is used to protect the puncture needle 7 in order to prevent danger.
The puncture needle 7 is used after being removed from the cap-shaped case 3, and after use, the puncture needle 7 is stored in the so-called cap 3 to be in a safe state and then discarded.

[0003]

However, as shown in FIG.
Since the conventional protection of the puncture needle 7 as shown in Fig. 2 is used with the puncture needle 7 and the cap case 3 separated, the cap case 3 may be lost during use or the puncture needle 7 may be removed after use. When inserting it into the cap case 3 for storage, you may pierce your finger or hand due to visual error,
Also, it is especially dangerous when the operator accidentally puts the cap on when the puncture needle that is contaminated with blood etc. is stowed when the puncture needle after use is removed from the body in a busy work due to emergency measures at the treatment site. In many cases, this may result in a so-called false needle accident in which the finger or hand holding Case 3 is stabbed, resulting in the risk of infection with viral hepatitis, AIDS, or the like.

Therefore, the inventors of the present invention have integrated the puncture needle portion and the storage case in order to prevent loss of the storage case and accidental needle accident as described above, and when storing the puncture needle in the storage case, Various studies have been made with the idea that the structure and mechanism are not such that the case is brought toward the tip direction of the puncture needle, and the puncture needle portion and the storage case are integrated and the puncture needle is stored on the side surface of the storage case. The present invention has been made on the basis of this finding, by not only preventing loss of the storage case at the time of use but also eliminating false needle accidents.

Therefore, a first problem to be solved by the present invention is to provide a protective cap for preventing accidental needle insertion, which can prevent the storage case from being lost during use or the like and can prevent accidental accidental needle insertion into a finger or hand. The object is to provide a puncture needle member and an infusion / transfusion set using the same. A second problem to be solved by the present invention is an erroneous puncture that can prevent the loss of the storage case during use and the like and can prevent an accidental needle puncture on a finger or hand despite its inexpensive and simple structure. (EN) It is intended to provide a puncture needle member having a protective cap for prevention and an infusion / transfusion set using the same.
