ようにしていた。2. Description of the Related Art Needless to say, a thin injection needle is attached to the tip of a syringe. A dedicated cap made of synthetic resin is attached to the injection needle for the purpose of ensuring hygiene before use and safety at the time of disposal. Thus, the conventional cap for an injection needle has an elongated sheath shape, and the work of covering the injection needle cap on the injection needle has a syringe with one hand and a cap for the injection needle with the other hand. The axis of the injection needle cap was aligned with the axis of the injection needle and was lowered straight.

Once inside the body, it may be contaminated with pathogenic bacteria. If you accidentally stick your finger with an injection needle that is contaminated with such pathogens, you may be infected with the pathogens. However, since the conventional cap for an injection needle has a structure in which the cap is dropped straight down toward the needle tip of the injection needle as described above, there is a possibility that a finger may be stabbed with a slight deviation. In particular, medical personnel who frequently handle syringes in their daily work do not have enough time to carefully cover the needle caps, and therefore a finger stick accident with a used needle is likely to occur with a high probability.

注射針用キャップを提供することにある。The present invention has been made in view of the above circumstances, and an object thereof is to provide a cap for an injection needle which is free from the risk of sticking a finger when covering the injection needle.

プを提供する。In order to achieve the above-mentioned object, the present invention is a cap for an injection needle which is detachably attached to an injection needle at the tip of a syringe, and which is from the middle of the height of the side surface to the lower end. There is provided a cap for an injection needle, which is provided with a longitudinal groove that is open over the entire length and through which at least a part of the body of the injection needle passes.

い。[Function] The body of the injection needle is inserted into the vertical dividing groove from the side and is slid in that state to insert the needle tip of the injection needle into the injection needle cap. If the cap for the injection needle is lowered to the base end portion of the injection needle in this state, there is no risk of piercing a finger with the needle tip of the injection needle.

(A)-(d) is a longitudinal section explaining a usage.

自在に取り付く基端部３ｂとからなる。The syringe 1 is well-known, and comprises a cylindrical main body 2 for containing a drug and an injection needle 3 attached to the tip of the main body 2. The injection needle 3 includes a needle body 3a having a thin tubular shape and a sharp tip, and a base end portion 3b detachably attached to the tip of the body portion 2 of the syringe 1.

Sheath-shaped cap body 4a that completely covers the needle body 3a of the needle, and skirt portion 4b that fits on the proximal end portion 3b of the injection needle 3.
Consists of The cap body 4a is a dome shape having a prismatic outer periphery and a round head.

ける。Thus, the cap 4 is formed with a vertical split groove 5 which opens from the middle of the height of one side surface of the cap body 4a to the lower end of the skirt portion 4b. The groove width of the vertical dividing groove 5 can be appropriately set depending on the material of the cap 4. For example, when a hard synthetic resin is used for the material of the cap 4, the groove width needs to be substantially the same as the diameter of the needle body 3a of the injection needle 3 (may be slightly thinner) or wider than it. On the other hand, when a soft synthetic resin is used as the material of the cap 4, the groove width of the vertical dividing groove 5 can be made considerably smaller than the diameter of the needle body 3a, and ultimately, a single score line may be used. In this case, since the soft synthetic resin is easily bent, the needle body 3a pushes the longitudinal groove 5 and opens it.

出る可能性があって危険である。The height of the vertical dividing groove 5 may be the same as or larger than that of the injection needle 3, but is preferably the injection needle 3.
It is better to set it lower than the needle tip. Then, the needle tip is positioned above the longitudinal groove 5 with the cap 4 fitted on the injection needle 3, so that the safety is high. If the needle tip of the injection needle 3 is located lower than the upper end of the longitudinal groove 5, the needle tip may come out of the longitudinal groove 5 when a lateral force is applied to the head of the cap 4. There is a danger.

This will be described with reference to (a) to (d). First, when covering the injection needle 3 with the cap 4, as shown in FIG.
The vertical groove 5 of is directed toward the injection needle 3 side. At this time, since the cap body 4a has a prismatic shape, the position of the vertical dividing groove 5 can be easily confirmed. Next, as shown in FIG. 3 (b), the cap 4 is inclined and the barrel of the injection needle 3 is inserted into the opening below the longitudinal groove 5. In this state, the cap 4 is erected as shown in FIG. 3C, and the needle tip of the injection needle 3 is put into the cap 4.
Then, the cap 4 is lowered as it is, and the skirt portion 4b is fitted to the base end portion 3b of the injection needle 3 as shown in FIG. When removing the cap 4, the cap body 4a may be held and pulled out as it is.

Of course, the present invention is not limited to the above embodiment. For example, in the embodiment, the cap body 4a has a prismatic shape, but other polygonal prismatic shapes or cylindrical shapes may be used. The shape of the cap body 4a may be cylindrical, and a flat surface portion may be provided on a part thereof. In this case, since there is only one flat surface portion, the position of the vertical dividing groove 5 can be more easily understood. Further, in the embodiment, the vertical dividing groove 5 is formed to have the same width from the top to the bottom, but the skirt portion 4b may be widened in a tapered shape as shown in FIG. By doing so, the body portion of the needle body 3a can be easily aligned with the vertical split groove 5.
