Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an accident prevention device that is used by being attached to a syringe needle cap in order to prevent syringe accidents caused by recapturing used syringe needles.

<Conventional Technology> Among medical workers such as doctors and nurses who come into contact with people with infectious diseases, needle accidents are the most common, and the risk of infection is extremely high. These needle accidents often occur during recapturing, and when returning the used needle to the needle cap (also called protector), the tip of the needle must be inserted accurately into the needle cap opening. It was difficult to use, and I sometimes accidentally stuck my finger holding the needle cap. Furthermore, if the needle is exposed and disposed of without being recaptured, there is a risk of infection to cleaning staff and the like during the subsequent disposal process.

Therefore, in order to prevent such syringe needle accidents, a syringe needle cap as shown in Figure 6 has been proposed (Utility Model Application No. 59-16648, Utility Model Application No. 59-1983).
(See Publication No. 19146).

This is designed to make it easier to insert the injection needle and to protect the fingers holding the injection needle cap by widening the open end of the injection needle cap into a brim shape.

<Problems to be solved by the invention> However, this type of injection needle with a cap must be sterilized in large quantities to avoid bacterial contamination before use, and a compact shape is required due to packaging issues. In contrast, with conventional caps with flanges, the flanges are bulky and
The problem was that this requirement was not met.

In addition, for such caps with flanges,
The problem is that it lacks versatility because it has to be manufactured for each syringe needle cap with a variety of external shapes, and a new cap with a flange must be produced in place of the cap without a flange that has been used up until now. The points were also hot.

In view of these conventional problems, the purpose of the present invention is to provide a needle accident prevention device that can be used as an accessory separate from the needle cap and can be used with caps having various outer diameters. shall be.

<Means for Solving the Problems> Therefore, the present invention consists of a synthetic resin plate-like body having an insertion portion smaller than the outer diameter of the syringe needle cap, and the surface of the plate-like body is provided with a syringe needle slip prevention material. Embossing is applied to the edge of the insertion part,
A flexible thin-walled portion that can be elastically deformed in the direction of diameter expansion is formed, and a thick-walled frame portion for preventing the needle from slipping is formed on the outer periphery of the plate-like body to prevent needle accidents caused by recapping. constitutes a prevention device.

Further, the thin portion may be formed in multiple stages or in a tapered shape, and the plate-like body may have a polygonal outer shape.

<Function> According to the above configuration, by inserting the injection needle cap into the insertion portion formed in the plate-shaped body, the flexible thin wall portion provided at the edge allows the injection needle to be inserted. Since it expands according to the outer diameter and shape of the cap, the needle cap and the insertion part of the plate-shaped body can be attached tightly together without any gaps between them.
This allows for recapturing (when returning the used needle to the needle cap before use).
In addition, even if the tip of the injection needle cannot be accurately inserted into the cap opening, the device according to the present invention protects the needle and prevents the finger from sticking while holding the cap.

Further, in this case, since the surface of the plate-like body is embossed with a satin finish or the like, it is possible to avoid an accident in which the injection needle slides on the surface of the plate-like body and pierces a finger.

Furthermore, since the thick frame portion is formed on the outer periphery of the plate-like body, it is possible to reliably prevent the injection needle from slipping out from the plate-like body.

<Example> Examples of the present invention will be described below.

1 to 3 show a first embodiment.

The plate-shaped body 1 is made of a synthetic resin having appropriate hardness and a certain degree of flexibility so that the needle tip does not penetrate, such as polypropylene, polyethylene, vinyl chloride, or an elastomer. In particular, polypropylene is suitable, and polyethylene has a high density. The one is good.

The plate-like body 1 has a thick part 2, which is the main part, about 0.8 mm thick, and a frame part 3 provided on the outer periphery of the thick part 2, which has a thickness of 1.2 mm.
It is a square with a side of about 25 mm, and has a hole 4 as an insertion part approximately in the center. This hole 4 is not necessarily limited to the central part as long as it is convenient for attaching the cap and can protect the fingers holding the cap. Further, the shape is not limited to a circular shape, but any shape that can be tightly attached to the cap may be used.

As shown in FIG. 2, the peripheral part of the hole 4 is formed thinner than the thick part 2 of the plate-shaped body 1 in multiple steps, and
The thinner part is defined as a first thin part 5, and the outside thereof is defined as a second thin part 6. From the center of hole 4
The inner diameter of the thin section 5 and the second thin section 6 is sequentially increased,
The wall thickness is also increased. in this case,
The first thin part 5 and the second thin part 6 constitute a flexible thin part.

The thickness of the first thin part 5 may be 1/5 to 4/5, preferably 1/3 to 1/2 of the thickness of the thick part 2. Furthermore, the thickness of the outer second thin part 6 is set to be the thickness between the first thin part 5 and the thick part 2. Further, the inner diameter of the hole 4 needs to be slightly smaller than the outer diameter of a commonly used cap, preferably slightly smaller than the outer diameter near the opening. For example, the inner diameter of the hole 4 is about 6.4 mm, the first thin part 5 has an outer diameter of about 7.5 mm, and the second thin part 6 has an outer diameter of about 10.0 mm. Note that depending on the outer diameter of the injection needle cap, a cap with suitably different dimensions may be used, but these dimensions are sufficient for those commonly used.

The first thin-walled portion 5 has increased flexibility so as to be able to accommodate the various outside diameters of the cap described above, and when the cap is inserted into the hole 4, it bends well and comes into close contact with the outside surface of the cap. It is better to do this.

In the above embodiment, two steps, the first thin part 5 and the second thin part 6, are provided in the structure of the flexible part, but one or two steps may be added. However, in addition to gradually increasing the thickness outward from the hole 4, the second thin part 6 may be formed thinner than the first thin part 5. This can be achieved by forming a groove around the outer periphery of the first thin part 5. This groove portion promotes flexibility of the first thin portion 5. Further, although an example is shown in which the first thin portion 5 is formed with a uniform thickness around the hole portion 4, the thickness does not necessarily have to be uniform and can be changed as appropriate. Furthermore, the thickness of the peripheral portion of the hole 4 may be alternately formed into thick portions and thin portions.

In addition, the thin wall portion is made of a flexible synthetic resin and has a thin wall, so that it can be made to respond well to variations in the outer diameter of the injection needle cap.

Further, the surface of the thick portion 2 is embossed with a satin finish or the like to prevent slipping.

The slightly thick frame portion 3 on the outer periphery of the plate-like body 1 provides strength to the whole plate-like body 1 and prevents the needle from slipping out from the plate-like body 1.

Next, the function of the device for preventing needle accidents caused by recapturing provided by the present invention will be described.

As shown in FIG. 3, a plate 1 is attached to the cap 10.
Attach the cap by pushing it as close to the opening 10a as possible, hold the other end with your fingers, and in this state insert the tip of the injection needle, which is the source of bacterial infection, into the cap. If the needle tip directly enters the cap, there will be no problem, but since the cap opening 10a is small, it may come off.At this time, even if the needle tip touches the plate-like body 1, it is possible to avoid pricking the fingertip.

Next, a second embodiment will be explained with reference to FIG.

In the first embodiment, the thin wall portion 7 is formed by a plurality of step portions, but the thin wall portion 7 may be formed by tapering as shown in FIG. Even in this case, similar effects can be obtained.

Next, a third embodiment will be explained with reference to FIG.

This is provided with radial slits 9 in order to give the one-stage thin wall portion 8 more flexibility, and in this case, it may be combined with any of the configurations of the thin wall portions described above. Even in this case, similar effects can be obtained.

Further, the outer shape of the plate-shaped body 1 is not limited to a square, but may be various polygonal shapes, circular or non-circular. However, if the syringe is circular, care must be taken to prevent the syringe from rolling.

<Effects of the invention> As explained above, according to the needle accident prevention device of the present invention, by attaching it to the outside of the needle cap and using it, it is possible to hold the cap during recapturing. This prevents you from accidentally pricking your finger with the tip of the needle.

Since the surface of the plate is embossed, it is possible to avoid an accident in which the injection needle slips on the surface of the plate and pierces a finger.

Furthermore, since the thick frame portion is formed on the outer periphery of the plate-like body, it is possible to reliably prevent the injection needle from slipping out from the plate-like body.

In addition, unlike conventional products that have a brim-like finger guard on the cap itself, this product can maintain the compact shape of the needle with a cap until use, so after mass sterilization, bacteria can be removed during use. It is particularly suitable for needs such as avoiding contamination.

Furthermore, the product of this invention has a flexible structure with a thin wall on the edge of the insertion part of the plate-shaped body, so it can be attached to syringe needle caps with various outer diameters and shapes. This is also an excellent point that conventional products do not have.

Furthermore, since this product is a plate-shaped body made of synthetic resin, patient names, drug names, etc. can be written on the surface of the plate-shaped body, and if this plate-shaped body is color-coded, it will be possible to mark the wards, medicines, etc. Classification of type, number of injections, etc. can be easily and accurately grasped.

Furthermore, by forming the thin wall portion in multiple stages or in a tapered shape, it can be given appropriate flexibility, and by making the plate-shaped body have a polygonal outer shape, rolling accidents can be prevented. It can be prevented.
