[Embodiment of the invention]

 Hereinafter, an example of the holder for a syringe according to the present invention will be described with reference to the drawings. FIG. 1 is a view showing the structure and appearance of a preferred embodiment of the syringe barrel holder of the present invention, (a) is a front view, (b) is a side view, and (c) is a rear view. . FIG. 2 is a view showing a state in which the syringe barrel holder of FIG. 1 is attached to a commercially available syringe.

As shown in FIG. 2, the syringe barrel holder of the present invention includes a barrel body 6 having a needle mounting portion 7 at a front end thereof and a flange portion 8 at a rear end thereof. It is used by being attached to the outer peripheral surface of the cylinder body 6, and as shown in FIGS. 1 (a) to 1 (c), the cylinder body 6 can be securely attached while surrounding the outer peripheral surface of the cylinder body 6. Finger holders 3a and 3b are integrally formed at both ends of a substantially cylindrical injection cylinder holder 1 having an inner peripheral surface 2 that can be held. Then, on one side surface of the syringe barrel holder 1, an injection barrel fitting / dismounting opening 4 is provided over the entire length of the syringe barrel holder 1 so that half or more of the circumference of the syringe barrel holder 1 is left. The syringe barrel 5 can be fitted and fixed from the side. The finger holders 3a, 3b are formed outward from both ends of the syringe barrel holder 1 on a plane forming an angle of 90 ° with respect to the center axis of the syringe barrel holder 1. It is formed to be larger than the flange portion 8 of the syringe barrel 5 to be attached so as to be easily caught by the fingertip when performing (see FIG. 2). In the present invention, the length in the circumferential direction of the syringe barrel holder without the syringe barrel fitting / dismounting opening 4 is generally about 5/8 to 3/4 of the circumference (FIG. 1). (See (b)). In the present invention, the finger holder portions 3a and 3b can distribute the force applied to the flange portion 8 during injection to the entire circumference of the flange portion excluding the injection cylinder fitting and removing opening 4. It is possible to prevent damage to the flange portion 8. Note that FIG. 2 illustrates an example in which the liquid medicine 11 is filled in the injection cylinder 5, and a piston having a piston head 9 at the tip of the piston rod 10 is also illustrated, and the needle mounting portion 7 has a cap. 12 is attached.

In the present invention, the finger holder portions 3a, 3b may be of a size such that the fingers are sufficiently caught during injection, and the shape thereof is not limited to the one illustrated in the drawings. . The finger holders 3a and 3b may have the same size and shape or may have different shapes, but it is preferable that they are a pair as shown in FIG. This is convenient because it is not necessary to consider the front and back of the holder when attaching the tool to the syringe barrel. In the present invention, the inner diameter of the syringe holder 1 may be appropriately selected according to the size (outer diameter) of the syringe to be attached, and it can be applied to various commercially available syringes.

When the holder for the syringe barrel of the present invention is attached to the syringe barrel, it suffices to push the spray barrel in parallel with the syringe barrel fitting opening 4 and push it in. Conversely, from the syringe barrel of the present invention. When removing the holder, it is only necessary to twist the finger holder portions 3a and 3b on both sides in opposite directions by hand, and the holder can be easily removed. The material of the holder for an injection barrel of the present invention which is suitable for such detachment may be any material that can be deformed when the holder is twisted by hand, and a flexible plastic such as polyethylene. Resins and polypropylene resins are preferred. The syringe holder of the present invention is generally used by inserting the syringe from the side at the time of use, and the injection cylinder is inserted from either side of the finger holder portions 3a and 3b. It may be inserted from the central axis direction of the holding body 1.

[0010]

【Example】

 A commercially available polyethylene resin was used to fabricate the syringe barrel holder of the present invention having the structure and shape shown in FIG. The dimensions of this holder were 34 mm in total length, 20 mm in width, 47 mm in height, 14.5 mm in inner diameter of the portion into which the injection cylinder was fitted, and 10 mm in width of the opening provided on the side surface. When the syringe holder of the present invention thus produced was used by attaching it to a commercially available glass syringe (capacity: 5 ml), the finger was stably caught on the finger holder part, and the injection drug was viscous. I was able to easily make an injection. Moreover, it was possible to easily remove it from the syringe barrel by holding the finger holder by hand and twisting it in opposite directions.

[0011]

[Effect of the invention]

 By attaching the syringe holder of the present invention to a commercially available syringe, the part where the fingertip is caught becomes large, and the syringe can be held stably, and the drug solution filled in the syringe is high. Even if it is viscous, it can be injected with a relatively small force. Further, even if the flange portion formed on the rear end side of the glass syringe barrel is broken, the finger can be protected by the syringe barrel holder of the present invention, which is safe. Furthermore, with a holder that is molded using flexible plastic resin, you can easily remove the holder from the syringe barrel by simply twisting the two finger holder parts in opposite directions by hand. There is also an advantage that it can be used many times by detaching it instead of being disposable. According to the present invention, the finger holders, which are positioned parallel to each other at regular intervals, allow the syringe to be stably placed on a desk or the like. It is hygienic as it does not come into contact with the upper surface of the needle, and is excellent in terms of preventing contamination of the injection needle.
