PROBLEM TO BE SOLVED: To prevent wrong sticking and contact with blood when an injection needle is put in and take out of a needle cover, by providing a wing or a injection needle with a rotation preventing means by which rotation of the needle cover is allowed which is divided into an axial direction of the injection needle by taking a junction part as a center of rotation, and rotation an angle more than a specified angle is prevented. SOLUTION: An injection needle 1 with fixed wings is composed of a sheet- shaped needle cover 3 and an injection needle which is covered with a needle cover 3, and is connected with the needle cover 3 by means of a junction part 5 in a needle base 4. The needle cover 3 can be divided into approximately equal two parts in an axial direction of a needle tube 2, and wings 3a, 3b which are the divided needle cover 3 can be rotated around the needle base 4 by making the junction part 5 as a rotational center. The injection cover 3 can easily be divided by opening the needle cover 3 from the head end side thereof when the injection needle 1 is used. The two divided wings 3a, 3b can be rotated at an angle made by both wings for example in a range of 0-180 deg., but further rotation is prevented by means of the wiring or a blade 9 which is provided on the injection needle 1. |
