Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a waste needle waste box. More specifically, the used injection needle can be easily and reliably removed from the syringe without damaging the fingers and the like, and the entire box can be safely and hygienically discarded, especially with a screw type needle such as a dental injection needle. The present invention relates to a waste needle waste box that can be suitably used for a double-ended needle type injection needle.

[Prior Art] Conventionally, in a dental anesthesia needle or the like, a screw-type double-headed needle type injection needle (a type in which a needle base is fixed to a syringe by a screw, is used on both the human body side and the liquid medicine side. It has many needles). Most of these types of injection needles have recently been disposable, and at present, after use, the injection needle is covered with a cap or container (hereinafter referred to as "cap"), and connected with a screw by a screw. After loosening the needle, the needle is removed from the syringe together with the cap, and then the cap containing the needle is put in an appropriate container or bag for disposal.

[Problems to be Solved by the Invention] However, the operation of inserting the injection needle into the cap is
At first glance, it seems simple, but while handling the needles dozens of times a day, it was easy for an accident to occur, such as when the hand slipped and the finger was injured. Such mistakes are not limited to the pain of a finger and pain, but the fact that the needle is inserted into the patient's body and, in some cases, the person treating the needle may cause hepatitis B and AIDS. It even contains a very serious risk of being infected by such viruses.

Furthermore, although the used needle is covered with a cap for a while, the cap comes off with a little momentum, for example, when carrying a used needle stored in a bag, the needle that pierces the bag may cause the needle or hand to break. There was also a risk of injuring the leg.

In view of the above points, the present invention can dispose of used needles, particularly double-headed needles such as dental needles, safely and easily by removing them from the syringe and discarding the used needles. The purpose is to provide a box.

[Means for Solving the Problems] The waste box of the present invention comprises (a) a cylindrical guide hole provided laterally in the box body, into which the tip portion of a syringe can be inserted, and (b) a lower surface of the guide hole. A slit formed so that the injection needle can be dropped, and (c) a fixed member and a movable member, which are provided in the inner part of the guide hole and hold the needle base of the injection needle screwed to the tip of the syringe. And (d) an operating rod for protruding the movable member to release the holding state, (e) an operating rod tip and a tubular guide. It is characterized by comprising a cap that can be selectively fitted into the opening of the hole.

[Operation] In the present invention, when the syringe is inserted into the tubular guide hole, the needle base of the injection needle is held by the holding means so as not to rotate, and the syringe is rotated counterclockwise by hand, the needle and the syringe are rotated. The screw with is removed. Then, when the operating rod is pushed to release the holding by the fixed member and the movable member, the injection needle held by the holding means falls into the box body. At that time, since the slit is formed on the lower surface of the guide hole, even with a double-ended needle type injection needle, the injection needle can be dropped smoothly without being caught anywhere, and the injection needle can be easily removed. Be seen.

When the injection needle is fully stored in the box, remove the cap at the tip of the operating rod and fit it into the opening of the guide hole.
It is safe because the opening of the waste box is completely closed and the injection needle inside the box does not come out even if it is wrong.

[Examples] Next, examples of the present invention will be described.

FIG. 1 is a perspective view of a waste box according to an embodiment of the present invention,
2 to 3 are perspective views showing the operation of the holding means, FIG. 4 is a front view of the guide hole and the holding means (the mark (16) is not shown in this drawing), and FIG. 5 is a guide. Fig. 6 is a vertical sectional view of the hole and the holding means, Fig. 6 is a partial sectional view showing a state in which a cap is fitted in the opening of the guide hole, Fig. 7 is a perspective view of a mounting plate, and Fig. 8 is formed in a box body. 9 to 10 are side views showing the mounting state of the box body.

In FIG. 1, (1) is a box body, (2) is a cylindrical guide hole,
(3) is a slit.

The box body (1) is a container for accommodating a used injection needle removed from the syringe, and the shape and size thereof are not particularly limited in the present invention.

As the material of the box (1), acrylonitrile butadiene styrene copolymer, polypropylene, polyethylene, polycarbonate, polystyrene, polyacetal, polyamide, vinyl chloride resin and the like can be preferably used.

A cylindrical guide hole (2) is laterally provided on the upper side wall of the box (1). The guide hole (2) is a cylindrical hole having a size into which the distal end portion of the syringe is inserted, and is formed in a tapered shape so that the guide hole (2) is tapered as it goes deeper than the opening. And, a slit (3) is formed on the lower surface thereof. The slit (3) has a width and a length that allow the needle on the drug solution side of a double-headed needle type injection needle to easily pass therethrough.

In addition, the operating rod (4) protrudes above the upper surface of the box (1),
A cap (5) is fitted to the tip of the cap. A mark (16) indicating the rotation direction of the inserted injection needle is integrally formed with the guide hole (2) on the opening of the guide hole (2).

A holding means (6) is provided at the back of the guide hole (2),
It will be described with reference to FIGS. The holding means (6) comprises a fixed member (7) and a movable member (8). The fixing member (7) is fixed to the box body (1) via a bracket (11). The movable member (8) can slide up and down in a guide (12) fixed to the box body (1). The operation rod (4) is integrally formed on the upper single part of the movable member (8), and a spring (13) is interposed between the lower end surface and the guide (12).

FIG. 2 shows a state in which the movable member (8) is pushed up by the spring (13). In this state, the fixed member (7) and the movable member
Holding portions (14) and (15) are formed at positions facing each other (8). Each of the holding parts (14) and (15) is formed in an arc shape so that the needle base of the injection needle can be easily grasped, and the surface has a ridge for preventing the needle base from rotating when grasped. Are formed.

Since the movable member (8) is supported by the spring (13), if the operating rod (4) is pushed down by hand, the movable member (8) can be pushed down as shown in FIG. . In this state, the holding part (14) and the holding part (15) are separated from each other, so that the injection needle whose needle base is grasped by them is released from the holding and drops downward.

The cap (5) is shown in FIG. The base portion (5a) of the cap (5) is adapted to fit with the distal end portion (4a) of the operating rod (4) and can be freely attached and detached. The removed cap (5) can be tightly fitted in the opening of the guide hole (2) as shown in FIG. It is preferable that the fitting is tightly fitted so that the cap (5) cannot be removed without permission.

As shown in FIG. 1, grooves (26) and (27) are formed on the bottom surface and the rear side wall of the box body (1). Grooves (26) are formed on both left and right sides of the box body (1) as shown in FIG. 8, and grooves (27) are also formed. Fig. 7 shows the mounting plate (3
0), and the mounting plate (30) is a plate (31) having substantially the same shape as the bottom surface of the box (1), and key-shaped locking claws (32) formed at the four corners. The locking claw (32) is fitted in the grooves (26) and (27) and can slide. An appropriate coupling member such as a double-sided tape (33) is attached to the back surface of the plate (31).

Then, as shown in FIG. 9, when the locking claws (32) of the mounting plate (30) are fitted to (27), the waste box (A) can be attached to the wall (W), and FIG. Mounting position (3
When the (0) is fitted in the groove (26), the waste box (A) can be mounted on the floor or desk.

Next, using the waste box (A) of the present embodiment, a method for removing a used injection needle sticker from the syringe and storing it in the case will be described.

First, the syringe (20) is inserted into the guide hole (2), and the needle base (22) is inserted between the holding part (15) of the movable member (8) and the holding part (14) of the fixed member (7). (See FIG. 5). Then, the syringe (20) is rotated counterclockwise to unscrew the injection needle (21) and the syringe (20). After that, when the syringe (20) is pulled out from the insertion port (2), the injection needle (21) moves the movable member (8) and the fixed member (7).
And is left behind in the box (1). In this case, the injection needle (21) is held by the elasticity of the needle base (22) itself.
Since it is firmly gripped by (14) and (15), one end of the injection needle (the end on the drug solution side) is pierced into the rubber stopper on the syringe side, such as a double-ended needle type injection needle. Even at this time, the holding force of the rubber stopper does not cause the injection needle (21) to come out of the guide hole (2) together with the syringe without separating from the syringe.

The injection needle (21) removed from the syringe (20) and held by the holding parts (14) and (15) has a movable member by the operation rod (4).
By pushing down (8), it can be dropped and stored in the box (1). In this case, the needle (23) on the drug solution side is slit.
As it falls through (3), make sure that the injection needle (21) is in the box (1).
Can be dropped inside.

Then, in this way, the needle is stored, and when the box is full with the needle, put the cap (5) on the operating rod.
Remove from (4) and push into the opening of the guide hole (2) to cover. Then, the stored injection needle will not pop out. Then you can discard the whole box.

The waste needle waste box of the present invention is a screw type or lure lock type (one in which the needle is inserted into the connecting portion of the syringe and then rotated slightly to one side to connect the two). It can be suitably used for needles, but among them, it is especially for double-headed needles (those that have needles on both the human body side and the drug solution side, such as injection needles for dental anesthesia needles) and blood collection needles. When used, the convenience is particularly remarkable due to the gripping effect of the sandwiching surface.

[Effects of the Invention] As described above, according to the waste box of the used injection needle of the present invention, the following effects can be achieved.

Since the slit is formed in the guide hole, even a double-ended injection needle will drop smoothly into the box without scratching,
The injection needle can be easily stored in the box body.

Since the used injection needle can be disposed of together with the box body and the guide hole can be covered with a cap, it is extremely safe and hygienic.

Even if one of the needles is stuck in the rubber stopper on the side of the syringe, such as a double-ended needle, the needle that has been removed from the syringe due to the gripping effect of the pinching surface When pulling out from the box,
Without coming out of the box with the syringe,
The needle can be reliably removed.
