[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a needle removing device for a used injection device, which is used for removing the injection needle from the injection device without directly touching the used injection needle. .

[0002]

2. Description of the Related Art When removing an injection needle from a used injection device, touching it directly with a hand may cause a secondary infection of a disease. However, it is very troublesome. Therefore, as shown in FIG. 5, in the center of the end plate b of the container a, a hole c into which the tip of the syringe is inserted and a squeezing hole d for squeezing the needle base are provided in series. It has been devised and used that after inserting it into the container, it is moved to the ironing hole d, and the syringe is pulled down into the container by pulling the syringe while holding the container a.

[0003]

However, in the conventional needle removing device for a used injection device, the tip of the syringe held by one hand is first inserted into the hole and then moved to the hole for squeezing, and the other end. You have to use both hands because you have to squeeze the injection needle into the container by pulling the syringe while holding the container with your hands, and you cannot easily remove it with one touch. If the injection needle is tightly fitted, the syringe must be pulled with a strong force, and in this case, the syringe will be shaken with the force of pulling, so the drug solution and blood remaining in the syringe may be scattered around. It was not easy to use. The present invention is a needle removing device for a used injection device in which the syringe is held with one hand, the tip of the syringe is inserted into the hole, and is pressed as it is, so that the needle can be removed easily and with one touch by the pressing force. Is intended to provide.

[0004]

In order to achieve the above object, the present invention provides a position on the end plate of a removal needle container in which one end plate is provided with a drop hole so as to communicate with the drop hole. A needle removal slider having a container cap having a communication hole formed therein, an insertion hole for inserting a syringe tip portion on the container cap, and a keyhole-shaped bifurcated wedge hole formed on the lower surface. Installed a needle removal mechanism that allows a movable table that is horizontally slidably moved across the insertion hole to be moved downward in parallel by a parallel crank mechanism, and a drop passage is provided between the container cap and the movable table. With a leaf spring curved in a U-shape being interposed, one end of the leaf spring is connected to be interlocked with the movement of the moving table and the other end is connected to the needle removing slider.

[0005]

In the needle removing device for a used injection device constructed as described above, the tip of the syringe with the needle is inserted into the insertion hole of the moving table, and the cylinder end of the syringe is placed on the surface of the moving table. When it comes into contact with and presses against, the moving table moves in parallel while descending against the leaf spring. At this time, the leaf spring is expanded, whereby the needle removal slider slides in the horizontal direction, and the keyhole-shaped bifurcated wedge hole portion forming the needle removal slider enters the injection needle fitting end surface portion of the tip of the syringe. Then, a force in the removing direction is applied to the end surface to remove the injection needle and drop the needle into the removal needle container.

【Example】

FIG. 1 is a partially cutaway front view of a needle removing device for a used injection device according to an embodiment of the present invention, FIG. 2 is a side view of the same, and FIG. 3 is a sectional view of a needle removing slider and a needle removing state. 4 is a plan view of the needle removing slider, and as is clear from these drawings, the end plate of the removing needle container 3 in which one end plate 1 is provided with a drop hole 2 is shown. On 1,
A container cap 5 having a communication hole 4 formed at a position communicating with the drop hole 2 is capped, and a needle removing mechanism B is fixed on the container cap 5 to remove the needle. Mechanism B
Is a base 11 integrally fixed to the container cap 5; two pairs of parallel links 12 pivotally attached to the left and right ends thereof; and a movable table 9 pivotally attached to the other end of the parallel links. The moving table 9 has an insertion hole 6 into which the tip of the syringe is inserted, and the needle removal slider 8 consisting of a keyhole-shaped bifurcated wedge hole 7 is formed in the insertion hole. Guide member 1 so as to cross 6
It is held by 3 and can be slid horizontally. Then, a leaf spring 10 curved in a U shape to the left and right is interposed between the container cap 5 and the moving table 9 so as to avoid the needle drop passage, and one end thereof is interlocked with the movement of the moving table 9. Is connected to one shaft 14 forming a parallel crank mechanism, and the other end is connected to the left and right of a moving shaft 15 engaged with the needle removing slider 8.

In the needle removing device for a used injection device constructed as described above, when the movable table 9 is pressed against the leaf spring 10 arranged on the lower surface thereof, the movable table 9 is horizontally moved by the parallel crank mechanism. While descending. At this time, the leaf spring 10 is compressed and both ends thereof are opened in the left and right directions in FIGS. 1 and 3, and the needle removal slider 8 is slid horizontally. Therefore, as shown in FIG.
When the tip of the syringe h with the injection needle e is inserted through the insertion hole 6 and the cylinder end of the syringe h is pressed against the surface of the moving table 9, the needle removal slider 8 slides in the horizontal direction. The keyhole-shaped bifurcated wedge hole 7 portion forming the needle removal slider 8 enters the needle fitting end surface portion of the distal end portion of the syringe h and imparts a force in the removal direction to the end surface to move the injection needle e. It is removed and dropped into the removal needle container 3 to be housed.

[0008]

As described above, the needle removing device for a used injection device according to the present invention is designed so that one end plate is provided with a drop hole and the drop needle container is provided with a drop hole. A container cap with a communication hole at a position communicating with the hole is capped, and the container cap has an insertion hole into which the tip of the syringe is inserted, and a keyhole-shaped bifurcated wedge hole is formed on the lower surface. The movable table holding the slidable needle removing slider horizontally slidable so as to cross the insertion hole is provided with a needle removing mechanism configured to be moved downward in parallel by a parallel crank mechanism. Between,
Avoid the drop passage, and interpose a U-shaped curved leaf spring,
Since one end of the syringe is connected to the movement of the moving table and the other end is connected to the needle removal slider, the tip of the syringe with the injection needle is inserted through the insertion hole, and the cylinder end of the syringe is inserted. The needle removal slider slides in the horizontal direction simply by abutting against the surface of the moving table and pressing it, and the keyhole-shaped bifurcated wedge part that forms the needle removal slider is the injection needle fitting end surface part of the tip of the syringe. The injection needle can be removed by applying a force in the removal direction to the end face, and dropped into the removal needle container. Therefore, according to the present invention, by holding the syringe with one hand and inserting the tip of the syringe into the hole and pressing it as it is, the injection needle can be easily removed with one touch without using both hands by the pressing force. A needle removing device for a used injection device can be provided, the used injection device can be easily treated, and a secondary infection of a disease due to the treatment can be prevented.
