カバー１３に納めることが出来る。In the injection needle cover 13 according to the present invention, the fitting groove 1
4 continues to the outlet 12, so that the base 18 of the injection needle is
Is applied to the end 17 of the insertion groove, and the base 18
When the needle tip 19 is lowered into the fitting groove 14 around the root 18 in the fitted state, the injection is performed so as to be guided to both edges 16 of the fitting groove. The whole needle 11 fits into the cover 13, so that the needle tip 19 can be stored in the cover 13 without being inserted toward the insertion port 12.
【００１１】そのように注射針１１を注射針カバー１３

注射針の根元１８を嵌込溝１４に嵌め損じ難く、その際
に針先１９が指先等に触れる危険はない。In this manner, the injection needle 11 is
In the first step, the base 18 of the injection needle and the end 17 of the fitting groove may be aligned, and the base 18 to be fitted is locked to the syringe body 20 which is firmly grasped.
It is difficult to fit the root 18 of the injection needle into the insertion groove 14, and there is no danger that the needle tip 19 touches a fingertip or the like.
【００１２】特に、嵌込溝の端１７がテーパーのある末
広形になっているので、注射針の根元１８を差込口１２
に嵌め込み易く、誤って注射針が指先等に刺さる危険は
皆無となる。In particular, since the end 17 of the fitting groove is tapered and divergent, the root 18 of the injection needle is inserted into the insertion port 12.
The injection needle is easily inserted into the fingertip, and there is no danger of the injection needle being stuck to the fingertip or the like.

危険もなくなる。A groove edge 16 on the insertion port side of the fitting groove 14 is provided.
a protrudes toward the outer surface side in the radial direction of the cover orthogonal to the axial direction of the cover, and the right and left groove edges 16a facing one end of the insertion groove on the insertion side are formed from the insertion surface to the outer surface. When the V-shaped edge 17 becomes divergent toward the side,
It is not necessary to increase the groove width C on the inner surface side, and therefore it is not necessary to increase the diameter of the insertion port 12 as well.
The mounting portion 21 of the injection needle can be strongly adhered to the insertion port 12, and there is no danger that the once inserted injection needle 11 comes off the cover 13.

かによってカバー１３の効用が妨げられることはない。Further, if the groove width C of the fitting groove on the inner surface side of the cover is made smaller than the groove width D on the outer surface side (C ≦
D) Even if the injection needle is slightly curved, the injection needle 11 can easily fit into the internal cavity of the cylindrical cover by sliding on the groove wall 22 inclined in a V-shape, and whether or not the injection needle 11 is curved. This does not hinder the utility of the cover 13.

When it is fitted into the internal cavity of the cylindrical cover, even if blood or the like adheres to the
It is also possible to prevent the sticking to the fingertip by sticking to the outer surface of 3 and the scattering of blood or the like to the surroundings due to the vibration of the needle tip 19.
