no. 1 Embodiment approach
[0033] The intradermal needle 10 of the present embodiment is as figure 1 As shown, the intradermal needle (medical needle) 10 is housed in a packaging body 12 that is individually packaged and provided as a product. The intradermal needle 10 is sealed within the package 12 until use so as to remain sterile.
[0034] The package 12 has a container 70 for housing the intradermal needle 10 and a sealing member 72 for closing the container 70 . The sealing member 72 is peeled off from the container 70 by the user during use, so that the intradermal needle 10 can be taken out of the container 70 .
[0035] The container 70 is formed in a cylindrical shape with a space inside. The bottom surface 74 of the container 70 is formed in a circular shape that is slightly larger than the diameter of the diameter-enlarged portion 30 of the hub 16 described later. In addition, the cylinder wall 76 stands up from the bottom surface 74 in the axial direction of the intradermal needle 10 . ...
no. 2 Embodiment approach
[0084] Refer to the following Figure 10 The intradermal needle 10A of this embodiment will be described. It should be noted that the internal structure of intradermal needle 10A is the same as image 3 The illustrated intradermal needle 10 is the same, so description is omitted. In addition, in intradermal needle 10A, for reference Figure 1 to Figure 9 The same components of the described intradermal needle 10 are assigned the same reference numerals, and detailed description thereof will be omitted.
[0085] The difference between the intradermal needle 10A of this embodiment and the intradermal needle 10 is the protector 90 . The protector 90 will be described below. The protector 90 is formed to be rotatable relative to the enlarged diameter portion 30 via a hinge portion 91 provided on the enlarged diameter portion 30 . The hinge portion 91 is provided on the inner side in the radial direction than the enlarged diameter portion 30 . That is, the distance R from the...
no. 3 Embodiment approach
[0093] Refer to the following Figure 11 ~ Figure 15BAn intradermal needle 10B according to a third embodiment of the present invention will be described. It should be noted that the intradermal needle 10B (refer to Figure 13A ) internal structure and image 3 The illustrated intradermal needle 10 is the same, so description is omitted. In addition, in the intradermal needle 10B, with reference to Figure 1 to Figure 9 The same components of the described intradermal needle 10 are assigned the same reference numerals, and detailed description thereof will be omitted.
[0094] Protector 80A of this embodiment (refer to Figure 13A ) by adding Figure 11 Cover assembly 82A is shown mounted on the Figure 12 The shown protector installation part 31 is constituted. Cover member 82A of this embodiment and Figure 5A The difference of the illustrated cover member 82 is that, in order to generate a resistance force in the middle of its turning movement to improve safety, an ...
