DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bandage for injection which covers and protects a puncture site after an injection needle is withdrawn during intravenous injection, subcutaneous injection, blood collection, infusion or the like.

[0002]

2. Description of the Related Art Conventionally, when intravenous injection, subcutaneous injection, blood collection, infusion, or the like is performed, in order to prevent infection from the puncture part after the needle is removed, a cotton swab or a disinfecting gauze is punctured. In order to eliminate the trouble of keeping the cotton swabs and disinfecting gauze by hand in recent years, in order to eliminate the inconvenience of holding the cotton swabs and disinfecting gauze by hand, a bandage for injection (small bandage)
Has been applied to the puncture part to protect the coating.

[0003] In the early type of this type of bandage for injection, since the adhesive portion was simply stuck to the entire surface of the release paper, there was a problem that it was difficult to remove the adhesive from the release paper. However, when sticking to the puncture part, the finger directly touches the adhesive part, so that the adhesive part becomes dirty and it becomes difficult to stick to the puncture part by clinging to the finger. there were.

In order to solve such a problem, as shown in FIGS. 4 and 5, an adhesive portion b is formed on the entire back surface of a band-shaped base material a made of a nonwoven fabric or the like, and the adhesive portion b is formed in a longitudinal direction. And a plurality of pads c are arranged side by side and affixed to one side (the right side in FIG. 4) of the base material a to a release paper e with a tab d interposed therebetween, and each of the pads c is individually Release paper e at a plurality of locations in the longitudinal direction of the base material a so as to be separated.
Plaster g for injection which has been cut to form a plurality of cutting lines f
Has been invented, and in this adhesive bandage g for injection, the knob d is folded back so as to protrude outward from the edge of the base material a. At the same time, the individual pieces are peeled off from the release paper e, and the exposed adhesive part b of the base material a is adhered to the skin surface so that the pad c comes into contact with the puncture part as it is. Attachment can be completed while peeling off from the base material a.

[0005]

However, in the conventional adhesive bandage g for injection as described above, the number of parts is increased by the amount that the tab d is interposed between the base material a and the release paper e. This leads to a new problem in that more garbage must be disposed of after use.

Further, since the entire periphery of the edge of the base material a is finally adhered to the skin surface in the same manner as in the case of the initial type of adhesive plaster for injection, there is no portion to be picked up when peeling off, and the skin surface is not removed. There was a problem that the edge of the attached substrate a had to be peeled off by scratching it with a nail.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and eliminates the need for a knob which has conventionally been interposed between a base material and a release paper to reduce the number of parts and to dispose of garbage which must be disposed after use. It is an object of the present invention to make it possible to extremely easily peel off the base material from the skin surface while leaving a portion to be picked up even after being applied to the skin surface, while reducing the amount of the base material.

[0008]

According to the present invention, an adhesive portion is formed on a back surface of a base material formed in a sheet shape while leaving a non-adhesive portion along one side of the base material. Against
Number of pads are arranged at required intervals in the direction along the non-adhesive part
Affix and cover the entire back surface of the substrate with the release sheet surface
The substrate so that it can be coated and the pads separated separately
Multiple cut lines on the back of the release sheet
An adhesive bandage for injection, characterized in that a wearing part is formed .

According to such an adhesive bandage for injection, a non-adhesive portion is picked and the base material is peeled off from the release sheet without interposing a knob between the base material and the release paper. Makes it possible to stick the adhesive portion of the base material to the skin surface in such a manner that the base material can be easily peeled off by picking the non-adhesive portion when peeling from the skin surface. Become.

[0010]

[0011] Further, the pads are so arranged as to be individually separable.
Multiple cut lines are formed in the material, and a solid
Since the fixed adhesive portion is formed, the back surface of the release sheet can be stuck and fixed to an appropriate fixing portion, and the work of peeling the base material for each pad from the surface of the release sheet can be performed with one hand. Becomes

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an example of an embodiment of the present invention. In the drawings, reference numeral 1 denotes a substrate 1 made of a non-woven fabric or the like formed in a belt shape. The adhesive portion 3 is formed leaving the non-adhesive portion 2 along one side portion (the right side portion in FIG. 1) extending in the longitudinal direction, and the longitudinal direction of the adhesive portion 3 (the direction along the non-adhesive portion 2). ), A plurality of pads 4 for covering and protecting the puncture portion are arranged and attached at required intervals, and the entire back surface of the base material 1 is covered with the base material 1.
It is covered by the surface of the wider release paper 5.

Here, it is preferable that the adhesive portion 3 on the back surface of the substrate 1 is formed using an adhesive such as an acrylic material which does not irritate the skin. What is necessary is just to use what consists of a soft material which has liquid absorbency, such as gauze.

Further, a plurality of cutting lines 6 are formed at a plurality of positions in the longitudinal direction of the base material 1 so that the pads 4 can be separated from each other.
For example, as shown in the drawing, the surplus portion 5a of the release paper 5 is made to protrude from one side of the base material 1 and the surplus portion 5a is formed from the other side of the base material 1 opposite to the surplus portion 5a. What is necessary is just to cut | disconnect and form the base material 1 with the release paper 5 to the position where it entered a little.

However, it is also possible to form the cutting line 6 only on the substrate 1 without cutting the release paper 5, and in this case,
The cutting line 6 may be a continuous cutting line 6 or a discontinuous cutting line 6 such as a sewing line. Also, the virtual
As shown by the line, the back surface of the surplus portion 5a of the release paper 5
The fixed adhesive portion 8 is formed in advance.

Thus, according to the adhesive bandage 7 for injection, the non-adhesive portion 2 is picked and the base material 1 is peeled off without any intervening piece between the base material 1 and the release paper 5. The adhesive portion 3 of the substrate 1 can be adhered to the skin surface by peeling the paper 5 from the paper 5 individually and the pad 4 hitting the punctured portion as it is. The substrate 1 can be easily peeled off by pinching the portion 2.

Therefore, according to the above embodiment, it is not necessary to interpose a knob between the base material 1 and the release paper 5, and the number of parts can be reduced. And the non-adhesive portion 2 of the base material 1 remains as a portion to be pinched even after being adhered to the skin surface, so that the non-adhesive portion 2 is picked and the base material 1 is very easily pulled from the skin surface. Can be peeled off.

Further, the rear surface of the surplus portion 5a of the front SL release paper 5
Since is formed a solid titration, the adhesive portion 8, one hand working the rear surface of the release paper 5 is fixed by pasting to a suitable fixed part, peeling off the substrate 1 from the surface of the release paper 5 for each pad It is possible to do with.

At this time, regarding the fixing adhesive portion 8,
For example, a plurality of similar adhesive bandages 7 are stacked so that the surplus portions 5a of the release papers 5 overlap each other, and the fixing adhesive portion 8 on the lower surface of the upper surplus portion 5a is covered with the upper surface of the lower surplus portion 5a. If you do this,
Only the fixing adhesive portion 8 of the lowermost layer of the adhesive bandage 7 for injection need be covered with a release paper (not shown).

FIG. 3 shows another embodiment of the present invention, in which a surplus portion 5a of the release paper 5 is made to be left-right symmetric by making the surplus portion 5a of the release paper 5 substantially the same as the above-described embodiment. Thus, even with such a configuration, the same operation and effect as described above can be achieved.

The adhesive bandage for injection of the present invention is not limited to the above-described embodiment, and the material of the substrate may be a resin sheet, cloth, paper or the like other than the nonwoven fabric.
Further, the this release sheet is also possible to a resin sheet or the like in addition to the release paper, and other, it is a matter of course that within the scope not departing from the gist of the present invention that various changes and modifications may be made.

[0023]

According to the above-mentioned bandage for injection of the present invention, the following various excellent effects can be obtained.

(I) Even if a knob is not interposed between the base material and the release sheet, the non-adhesive portion is picked, the base material is peeled off from the release sheet, and the pad is directly brought into contact with the punctured part. The adhesive portion can be attached to the skin surface, so that the number of components can be reduced by eliminating the need for a knob which has been conventionally required, thereby reducing the amount of dust that must be disposed after use.

(II) Since the non-adhesive portion of the base material remains as a portion to be picked up even after being attached to the skin surface, the non-adhesive portion can be picked and the base material can be peeled off from the skin surface very easily.

[0026] (III) a back surface of the release sheet can be fixed paste to a suitable fixed portion, because the task of peeling off the substrate from the surface of the release sheet can be performed with one hand, pull the base A series of operations from peeling to pasting to the skin surface can all be performed with one hand.
