FIG. 1 (a) is a perspective view showing an embodiment of the needle tip cap of the present invention, and FIGS. 1 (b) and 1 (c) are FIG.
It is a longitudinal cross-sectional view of (a).

Referring to FIG. 1A, the needle tip cap 6
Is made of an elastic material such as rubber and has a cross-sectional area longer than the length of the needle and larger than the cross-sectional area of the needle. The one end surface is the injection needle insertion surface 1, and it has a sufficient area such that it is easy to pierce the needle and that cracks and the like do not occur even when the needle is pierced.

The injection needle insertion 1 may be flat as shown in FIG. 1 (b), but it may be provided with an inverted drooping shape as shown in FIG. 1 (c) as a guide to the center when the needle is pierced. Even better.

Further, even if the injection needle is pushed all the way to the base, it does not penetrate, but it has a sufficient length to accommodate other kinds of needles,
It is large enough to protect even if the human body touches it. The shape does not have to be particularly limited.

Further, when the needle is pierced, the needle can be smoothly inserted, has elasticity such that the needle cannot be easily removed after the puncture, and the syringe is made of bubble-free rubber from which the residual drug solution does not exude.

Therefore, as a material, these conditions are satisfied,
Rubber materials such as natural rubber, neoprene rubber, urethane rubber, and silicone rubber are considered.

FIG. 2 is a view showing an embodiment of an injector device using the needle tip cap 6 of FIG. 1. In the figure, a magazine 7 stores a plurality of needle tip caps 6 on the same circumference at substantially the same pitch. This is a possible structure. At the center of the magazine 7, there is provided a rotary drive 8 having a rotating shaft 8 supported by a bearing 11 and having a bevel gear 10, and a bevel gear 9 mounted so as to mesh with the bevel gear 10. The magazine 7 is rotationally driven by the driving body 8.

With the magazine 7 positioned, the insertion guide portion 3 of the syringe 2 is coaxial with the needle tip cap 6.
Is provided in the main body 4.

In such a structure, the used syringe 2 is inserted into the insertion guide portion 3 of the main body 4. At this time, it is assumed that the needle 5 of the syringe 2 and the needle tip cap 6 in the magazine 7 are coaxially positioned. Therefore, the needle 5 of the syringe 2 is stuck in the center of the needle tip cap 6.

Further, the needle tip is pressed to the base so that the needle tip completely covers the needle tip cap 6. As a result, the syringe 2 and the needle tip cap 6 can be disposed of as an integrated body. In this state, the syringe 2 and the needle tip cap 6 are removed from the main body 4 as an integrated body and discarded in a predetermined disposal place.

Next, the rotary driver 8 is operated. This rotation is caused by the bevel gear 1 fixed to the rotating shaft 8 from the bevel gear 1.
Transmitted to 0. Since the rotating shaft 8 attached to the center of the lower surface of the magazine 7 rotates smoothly by the bearing 11, the rotating shaft 8 moves smoothly until the next needle tip cap 6 becomes coaxial with the insertion guide portion 3. After rotating at a constant pitch, the operation of the rotary drive body 8 is stopped. At this time, the next syringe 2 can be inserted.

Further, when the needle tip cap 6 in the magazine 7 becomes empty, the needle tip cap 6 can be inserted from the insertion guide portion 3 and the upper portion of the main body 4 is opened to supply the needle tip cap 6. It is also possible to do so.

The intermittent feed mechanism is not limited to this example, but may be a worm gear or an ordinary gear. Needless to say, a mechanism using a cam such as Geneva can be used.

FIG. 3 is a view showing another embodiment of the injector processing device according to the present invention, and the same parts as those in FIG. 2 are designated by the same reference numerals. As shown in the drawing, a magazine 7 capable of accommodating a plurality of needle tip caps 6 (not shown) in a straight line, a guide 21 and a rack 18 are fixed in parallel to the lower surface of the magazine 7 and are attached so as to engage with the rack 18. Pinion 19
The insertion guide portion 3 is coaxial with the needle tip cap 6 at the position where the rotary drive body 8 having the
And a main body 4 provided with.

Next, the operation of the apparatus shown in FIG. 3 will be described.
The used syringe 2 is inserted into the insertion guide portion 3 of the main body 4. The needle 5 of the syringe 2 and the needle tip cap 6 in the magazine 7 are coaxially positioned. Therefore, the needle 5 of the syringe 2 pierces the center of the needle tip cap 6. Further, the needle tip 5 is pushed to the base of the needle tip so that the needle tip 5 can completely cover the inside of the cap 6. In this state, the cap 6 is removed from the main body 4 and discarded at a predetermined disposal place.

Next, the rotary driver 8 is operated. This rotation is transmitted from the pinion 19 to the rack 18. Since the magazine 7 is guided by the guide 21, it smoothly moves straight. After going straight for a fixed pitch, the operation of the rotary drive body 8 is stopped. This allows the next syringe 2 to be inserted.

The supply method when the needle tip cap 6 in the magazine 7 becomes empty is the same as in the embodiment of FIG.
Needless to say, the intermittent feeding mechanism is not limited to this example, and can be a mechanism using a feed screw, a belt, and a wire.
