The self-standing function part is formed by self-standing piece parts (16) formed by dividing the main folding line (13) to forked lines (13A) near the root part of the injection needle and notching the sheet to approximately U shapes with the respective ends of the forked lines (13A) as one-side ends. The self-standing piece parts (16) are provided with sub-folding lines (14).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a technique for preventing a needle stick accident in a medical syringe.

[0002]

2. Description of the Related Art Since a used injection needle has a risk of transmitting AIDS, hepatitis, etc., various measures have been taken for handling the used injection needle. As a part of this measure, the present applicant has invented a sheet material containing a used injection needle and filed an international application (International Application No. PCT / JP99 / 05493).

[0003]

The sheet material shown in FIGS. 9 and 10 is formed into a V-shape when the user of the syringe puts it on a table top or the like with a fold before injection. You can stand alone on that surface. Since the sheet material is coated with an adhesive, the used injection needle is placed at the center of the V-shape and folded further to be included in the sheet material.
At this time, the V-shaped apex of the sheet material is substantially flush with the upper surface of the table. In the case of a winged needle in which the point from the tip of the injection needle to the base of the injection needle is formed on substantially the same plane, the used injection needle is placed at the center of the V-shape and at the same time the base of the injection needle, ie, the wing. The adhesive action works on the part,
The injection needle is fixed.

As shown in FIG. 9, in the case of a syringe needle for a disposable syringe, the outer diameter of the syringe cylinder is several times larger than the root of the syringe needle. When the syringe cylinder is placed shallowly without being placed on the sheet material, both the injection needle itself and the base of the injection needle are in a state separated from the V-shaped apex. In this state, there is no sticking action, so there is a concern that the needle will spill until it is folded further and contained. Therefore, in order to adhere the base portion of the injection needle, the sheet material may be bent anew so as to be floated from the upper surface of the table by the outer diameter of the syringe cylinder. However, since there is no fold line for this, where the user may bend, and if the sheet material is made of a material that can withstand the penetration of the needle, there is resistance to bending, and as a result, it must be bent again Was virtually difficult. On the other hand, if you attach the syringe cylinder to the sheet material,
Although the sheet material and the syringe barrel are fixed, it is difficult to determine the relative position between the sheet material and the syringe barrel. In particular, as shown in FIG. 10, when the relative position of the syringe cylinder is too deep with respect to the sheet material, when the sheet material is further folded and included thereafter,
There is also a risk that the needle tip protrudes from the edge of the sheet material. However, medical sites handling syringes require quick and accurate work.

[0005] In view of the above, according to the first aspect of the present invention, when using a syringe needle for a disposable syringe, the position where the syringe needle is placed on the sheet material can be easily determined, and the tip of the syringe needle can be positioned at the tip of the sheet. It is an object of the present invention to provide a needle containing device which has a low risk of protruding or spilling from an end. Another object of the present invention is to provide a syringe needle containing device that can be operated quickly and accurately with a small force.

[Means for Solving the Problems]

[0006] (1) The invention according to claim 1 is a sheet-like needle-containing device for wrapping a used injection needle from the pointed end to the root of the injection needle, which reduces bending resistance. Bending line (13) formed as described above
And an adhesive (12) applied to the inner surface of the sheet material (10) when the injection needle is wrapped, and the sheet material (10) using the main folding line (13) before wrapping the injection needle.
Has a self-supporting function part that makes the entire sheet material (10) self-supporting when the sheet is folded, and the self-supporting function part has a main folding line (1).
3) is a bifurcated line (13A) near the base of the injection needle, and a free-standing piece (1) formed by providing a cut in a substantially U-shape with each end of the bifurcated line (13A) as one end.
6), and the sub-folding line (1)
4) The present invention relates to a needle containing device provided with 4).

(Definition of terms) The "self-supporting piece" includes not only a wing-shaped portion formed by a substantially U-shaped cut but also a central portion between the wing-shaped portions. Not only the case where the sub-folding line is formed at the central portion but also the case where the sub-folding line is formed only at the wing portion are included in the scope of the present invention.
Furthermore, the case where a sub-fold line is formed at the root of the wing portion is also included in the scope of the present invention. The “injection needle” is intended to include a winged needle (40) used for infusion and the like in addition to the injection needle (50) for a disposable syringe. The reason that the injection needle is wrapped from the tip to the root of the injection needle is that the surface of the needle part (51, 41) of the injection needle is highly slippery and thin, so that only the injection needle is wrapped and the injection needle is sheet material. Because it is difficult to fix to The phrase “from the tip of the injection needle to the base of the injection needle” is intended to mean at least from the tip of the injection needle to the base of the injection needle. For example, even if the sheet material (10) wraps around the syringe barrel (53) of the syringe and the tube (43) of the winged needle (40), it is within the scope of the present invention.

[0008] The "base portion of the injection needle" is a portion made of resin that is thicker than the injection needle portion. For example, a needle base (52) of a disposable syringe injection needle (50), a syringe barrel (53) of a syringe or a wing part (42) of a winged needle (40), etc.
The adhesive effect is higher than that of the needle portions (51, 41). The “main bending line” is a line provided substantially at the center of the sheet material (10) for wrapping the injection needle, and may be a continuous straight line,
It may be a wavy line. Ideally, a material that reduces bending resistance but does not reduce piercing strength is desirable. Specifically, when the sheet material (10) is mainly made of paper or a material similar to paper, there is a so-called “scoring (also called creasing, creasing, cleaving, etc.) processing” and the like. When (10) is mainly made of resin, there is a so-called "hinge processing".

The "sheet material" is formed of a material that can be formed into a sheet, such as paper, cloth, a resin sheet, or a material obtained by combining them. The “cut” is a process of linearly penetrating the thickness direction of the sheet material (10), and is formed by, for example, a punching process used for thick paper or the like. Here, the term “substantially U-shaped” for the notch (15) is not limited to the “U-shaped” but is intended to include, for example, “semicircular” and “oval” cuts. The “sub-folding line” is a line arranged on both sides of the main folding line, and if the main folding line is a valley fold, the sub-folding line is a mountain fold.
The processing method of the sub-folding line is the same as that of the main folding line.

(Operation) The user of the syringe uses the main folding line (13) to prepare the sheet material (1) in preparation for injection.
When (0) is folded into a valley fold, it is bent up to the end of the forked line (13A), but the free-standing piece (16) is formed due to the presence of the cut (15). This self-supporting piece (1
When the sheet material (10) is placed on the upper surface of the table or the like using 6), the entire sheet material (10) forms a V-shape, and the apex of the V-shape is substantially coplanar with the upper surface of the table and becomes self-standing. Further, when the self-standing piece (16) is bent in a mountain fold using the sub-folding line (14) and placed on a table upper surface or the like, both ends of the self-standing piece (16) become feet, so that the V-shaped apex portion is formed. Becomes independent from the table top.

For this reason, when using the injection needle (50) for a disposable syringe, the gap between the V-shaped apex of the sheet material (10) and the upper surface of the table is the outer diameter of the syringe cylinder (53) and the root of the injection needle. Make up for the difference in diameter with the part. Secondary folding line (14)
Is located at a position suitable for compensating for the diameter difference, and is provided to reduce bending resistance. Therefore, it becomes easy to place the injection needle so that the shoulder of the syringe cylinder (53) is aligned with the V-shaped end of the sheet material (10) on the side of the self-standing piece (16). Easy to match without being too deep or shallow. In addition, since the sticking action to the base of the injection needle works at the time of placement, there is an advantage that the needle is easily stabilized.

(Claim 2) The invention according to claim 2 limits the injection needle containing device according to claim 1, wherein the two or more sub-folding line portions are provided, and at least 2. The injection needle containing device according to claim 1, wherein the device includes one proximity portion.

(Definition of terms) Here, "at least one
The “places” are not limited to points that are close to each other, but include cases where the points are close to each other with a certain range. The “proximal location” is not limited to the case where the plurality of sub-folding lines intersect with each other, but also includes a case where there are locations approaching each other.

(Function) When the self-standing piece (16) is bent using the sub-folding line, it is bent with the thumb and the index finger of one hand. Here, the self-standing piece portion (16) is smaller than the sheet material (10), and even if the bending resistance is reduced by the sub-folding line (14), the bending moment by the finger is not large, so it is difficult to bend. Here, as a result of performing various experiments using the sub-folding line (14) as a crimping line, the sub-folding lines (14) are closer to each other than when the sub-folding line (14) is two parallel pressing rules. It has been found that when they meet at one place, they can be bent very easily by a finger. In addition, it has been found that the effect can be obtained not only when they intersect but also when they are close to each other. As a result, bending can be performed with a small force of a finger, which can contribute to quick and accurate work.
