On the inner side of a, a plurality of circumferential grooves are continuously formed. The nozzle of the syringe barrel 31 is formed with an external thread, and the nozzle of the syringe barrel 31 is screwed into the groove formed inside the tip portion 30a. Further, the groove formed inside the chip portion 30a may be formed as an internal screw.

Put on the cap and dispose of the case. Further, a plurality of ribs are formed on the outer periphery of the tip of the injection needle.
Also, ribs are similarly formed on the inner peripheral surface of the storage opening of the case, so that when the used syringe needle is attached to the used syringe needle while the used syringe needle is still attached to the syringe outer cylinder 31, the ribs are connected to each other. When the case is engaged and the case is rotated, the used injection needle can be removed from the nozzle.

きるようにしたものが存在している。[0006] In the work of removing the used injection needle from the syringe barrel 31 and discarding it, there is a danger that the used injection needle may accidentally stick into the skin during the operation and cause serious infection. It has been pointed out that there is something. Therefore, there is a type in which a used injection needle can be removed from the nozzle of the syringe barrel 31 in the case of the injection needle as described above.

以下に示す内容のものが記載されている。However, the case itself accommodating the injection needle is an extremely small-diameter cylindrical body, and an operator sometimes performs such an operation under various circumstances. Accidentally, a used injection needle may pierce the skin. Therefore, Japanese Patent Application Laid-Open No. 9-224985 discloses a device for disposing of used injection needles. Although the above invention includes various embodiments, the following contents are described in the embodiments.

である。That is, after the syringe stops at the receiving position, the motor or the driving means for fixing the injection needle provided with the weight is rotated through the hollow shaft separating the injection needle space portion, so that the needle removal operation is performed. The needle remover is a fastener provided with a pair of toothed flat plates that operate in front or substantially simultaneously to grip or pinch and fix the injection needle mounting portion.

The fixed used needle also rotates,
The used injection needle falls off the nozzle of the syringe barrel 31 and falls into the storage device as it is.

きるものであるとされている。In this way, when the used injection needles accumulate in the storage device, the entire storage device is discarded. According to the above procedure, the worker removes the used injection needle from the syringe barrel 31 without touching the used injection needle portion at all, and stores the used injection needle as it is in the storage device. It is said that the safety of workers can be sufficiently ensured.

The tip of the toothed flat plate has many teeth formed in a sawtooth shape. When the tip portion 30a of the used injection needle is actually pinched with such a cutting edge, the following problems occur.

チップ部３０ａとが空回りしてしまうことがある〔図１
０（Ａ）参照〕。First, the number of ribs formed along the axial direction of the tip portion 30a differs depending on the manufacturer. As shown in FIGS. 9A, 9C, and 9D, there are many cases in which four, six, eight, and the like are used. Therefore, the intervals between adjacent ribs are also different. Therefore,
If the teeth at the tip of the toothed flat plate are the saw-toothed teeth c, as the number of ribs of the tip portion 30a increases, the saw-toothed teeth c at the tip of the toothed flat plate become the tip portion 30a.
Incompletely caught on the rib of
0a, and the tip portion 30a is inserted into the syringe barrel 31.
The toothed flat plate and the tip portion 30a may run idle even when the tip portion 30a is rotated so as to be removed from the device [FIG.

When the ribs are thick, they cannot engage with the above-mentioned saw-tooth c (see FIG. 10 (C)), and even when the interval between adjacent ribs is narrow, they cannot engage with the saw-tooth c. (See FIG. 10D).

There is a danger of an accident in which the used injection needle sticks into a worker's finger or the like as described above.
