Abstract

PROBLEM TO BE SOLVED: To lessen uncomfortable odd feel by grittiness in applying a first-aid adhesive plaster to the skin surface by forming a base material to a three- layered structure obtd. by holding a net for imparting required toughness between a pair of synthetic resin films and thermally fusing both films. SOLUTION: A pad for hygienically protecting a wound part by applying the pad to the wound made on the skin surface is stuck to the suitable position of the tacky adhesive layer 2 of the base material 1 which is formed to a sheet form and is formed with the tacky adhesive layer 2 on its rear surface. The entire area of the rear surface of the base material 1 is covered with a release sheet together with the pad. The base material is formed as the three-layered structure obtd. by holding the net 9 for imparting the required toughness between a pair of the synthetic resin films 7, 8 and thermally fusing the films 7, 8. As a result, the direct contact of the net with the skin surface is eliminated and since the smooth film on the inner side eventually comes into contact with the skin surface, the feel of the grittiness by the mesh of the net is lessened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an emergency bandage.

[0002]

2. Description of the Related Art Conventionally, first-aid bandages for hygienically protecting wounds formed on the skin surface have been well known, but when cooking or bathing, the wound area is protected with the first-aid bandages. However, the protection pad applied to the wound may become wet, causing germs to grow easily, or the wound may be soaked with water and pain may occur. Had to be replaced with a new bandage.

[0003] For this reason, in recent years, the base material of the first-aid bandage is made of synthetic resin having both waterproofness and moisture permeability so as to protect the wound from being wetted by water, and is being started to spread. .

[0004] As a synthetic resin having both waterproofness and moisture permeability used for a base material, for example, 25 to 30 μm is used.
m, but generally, this type of synthetic resin film is too soft and easily wrinkled,
There is a drawback that it is difficult to adhere to the skin surface. Generally, as shown in FIG. 9, a net b made of nylon or the like is heat-sealed to the back surface of a base material a made of a polyurethane film or the like formed in a sheet shape. Thus, the pressure-sensitive adhesive layer c is formed after imparting the required toughness.

[0005]

However, in the conventional structure as described above, when the base material a is attached to the skin surface, the net b comes into direct contact with the skin surface. When the user touches the object, the mesh of the net b is rough and uncomfortable.

Further, the substantial heat-sealing area of the net b to the back surface of the base material a is extremely small, and the pressure-sensitive adhesive layer c
Because the adhesive force by the will act directly on the net b, when peeling the base material a from the skin surface, a part of the net b is easily separated together with the adhesive layer c from the back surface of the base material a,
There is a possibility that a part of the adhesive layer c or the net b may remain on the skin surface.

[0007] The present invention has been made in view of the above circumstances, and when applied to the skin surface, prevents the net from directly touching the skin surface, thereby reducing unpleasant discomfort due to roughness, and reducing the base material from the skin surface. The purpose of the present invention is to prevent a part of the pressure-sensitive adhesive layer or the net from separating from the back surface of the base material and not remaining on the skin surface when peeled off.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a base material formed in a sheet shape and having an adhesive layer formed on the back surface thereof, a pad attached to an appropriate position of the adhesive layer of the base material, In an emergency bandage comprising a release sheet covering the entire back surface of the material, the base film was heat-sealed with a net between the pair of synthetic resin films sandwiching a net for imparting required toughness. It is characterized by being formed as a three-layer structure.

[0009] According to such an emergency bandage, when the release sheet is peeled off and the substrate is attached to the skin surface, the net does not directly touch the skin surface, and the net has a smooth inner surface. Because the film will touch, especially when you touch the object by sticking it to your fingertips, etc.
The feeling of roughness due to the mesh of the net is reduced, and unpleasant discomfort is remarkably reduced.

Further, the net for imparting the required toughness to the base material is sandwiched between the two films which are strongly bonded to each other with a sufficiently large heat-sealing area through the gap of the net. Since the pressure-sensitive adhesive layer formed well without inclusions on the entire back surface of the inner film does not directly exert an adhesive force on the net, when the substrate is peeled off from the skin surface, This prevents a problem that a part of the adhesive layer or the net is separated and remains on the skin surface.

Further, in the present invention, the pad can be formed in a rectangular shape, and the base material and the release sheet can be formed in a gourd shape having a constricted portion near the middle portion in the longitudinal direction of the pad. By doing so, it is possible to obtain an emergency bandage which can be satisfactorily stuck to a fingertip which has been difficult to stick in the past, and more specifically, a base material in which the vicinity of the middle portion in the longitudinal direction of the pad is aligned with the fingertip. At one end of the base material, and the other end of the base material on the back of the finger.The side of the base material that protrudes outward in the width direction of the finger is placed inside. The base material can be attached so as to be folded and wrapped around the fingertip.

[0012]

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

1 to 8 show an embodiment of the present invention. FIG. 1 is a plan view of this embodiment viewed from the front side.
2 is a bottom view of the embodiment as viewed from the back side, and FIG. 3 is a bottom view of the embodiment, where 1 is formed in a sheet shape and an adhesive layer 2 is formed on the back surface. A base material is shown. A pad 3 is provided at an appropriate position of the pressure-sensitive adhesive layer 2 of the base material 1 so as to be applied to a wound formed on the skin surface and hygienically protect the wound part.
Is adhered, and the entire back surface of the base material 1 is covered with the release sheet 4 together with the pad 3.

In this embodiment, in particular, the pad 3 is formed in a rectangular shape, and the base material 1 and the release sheet 4 are formed in a gourd shape with a constricted portion 10 near the longitudinal middle portion of the pad 3. This is illustrated in the case of an emergency bandage which can be satisfactorily applied to a fingertip which has been difficult to apply in the past.

A release sheet 4 covering the entire back surface of the substrate 1 is formed by applying a silicone coat to one surface of a paper sheet so that the adhesive layer 2 of the substrate 1 can be easily released. Is divided into a pair of release sheet pieces 4a and 4b with the vicinity of the middle part in the longitudinal direction as a boundary part 5, and the boundary part 5 between the release sheet pieces 4a and 4b is formed at the end of one release sheet piece 4a. The end of the other release sheet piece 4b is superposed on the folded portion 6 thus formed.

In such an emergency bandage, the base material 1
As shown in a schematic cross-sectional view of FIG. 4, the two films 7, 8 were heat-sealed with a net 9 for imparting required toughness between a pair of synthetic resin films 7, 8. It is formed as a three-layer structure, and the material of each of the films 7 and 8 is preferably, for example, a polyurethane film having both waterproofness and moisture permeability. The thickness of each of the films 7 and 8 is about 20 μm. Is preferred.

The material of the net 9 sandwiched between the films 7 and 8 may be a natural fiber such as silk, cotton or wool, or a synthetic fiber such as nylon. The denier may be about 15 deniers, and a regular hexagonal mesh having a side x of about 0.7 mm may be formed as shown in FIG.

Thus, when using such an emergency bandage, the end of the other release sheet piece 4b superposed on the folded portion 6 of the one release sheet piece 4a is picked and the release sheet piece 4b is peeled off. As a result, one side of the pressure-sensitive adhesive layer 2 of the base material 1 is exposed, and as shown in FIG. 6, one side of the exposed pressure-sensitive adhesive layer 2 is moved in the vicinity of the middle part in the longitudinal direction of the pad 3 with respect to the wound part of the fingertip. It is attached to the abdomen of the finger (possibly the back side) while applying, and the side of the base material 1 that protrudes outward in the width direction of the finger is folded inward and attached.

Next, the release sheet piece 4a left on the pressure-sensitive adhesive layer 2 of the base material 1 is peeled by pinching the folded-back portion 6, and the other side of the pressure-sensitive adhesive layer 2 exposed as shown in FIG. Then, the base material 1 is folded back at the constricted portion 10 so that the base material 1 is attached to the back side of the finger (the abdominal side when pasted to the back side first), and then the abdomen side of the finger (FIGS. 6 and 7) (The side opposite to the illustration in the drawing), the side of the base material 1 that protrudes outward in the width direction of the finger is folded inward, and the attachment of the base material 1 is completed so as to wrap around the fingertip.

As apparent from FIGS. 6 to 8, the side of the gourd shape attached to the base material 1, which is formed with a relatively small width, is attached first, and the relatively wide width is formed. Needless to say, it is preferable to attach the side formed by the above later.

As described above, the base material 1 of the first-aid bandage stuck to the fingertip is a net for providing a required toughness between the pair of synthetic resin films 7 and 8. Since the two films 7 and 8 are formed as a three-layer structure that is heat-sealed with the film 9 interposed therebetween, the net 9 does not come into direct contact with the skin surface, and the smooth inner film 7 does not touch the skin surface. , 8 are touched, and when the object is touched with the fingertip to which the base material 1 is attached, the feeling of roughness due to the mesh of the net 9 is reduced, and the uncomfortable feeling of discomfort is significantly reduced.

Further, the net 9 for imparting the required toughness to the base material 1 is sandwiched between the two films 7 and 8 which are strongly bonded to each other with a sufficiently large heat-sealing area through the gap of the net 9. In addition, since the pressure-sensitive adhesive layer 2 formed well without any inclusions on the entire back surface of the inner films 7 and 8 does not directly act on the net 9, the skin When the base material 1 is peeled off from the surface, it is possible to prevent a problem that a part of the adhesive layer 2 or the net 9 is separated and remains on the skin surface.

In this embodiment, the pad 3
Are formed in a rectangular shape, and the substrate 1 and the release sheet 4
Is formed in the shape of a gourd in which the vicinity of the middle portion in the longitudinal direction of the pad 3 is formed as a constricted portion 10, so that it is possible to satisfactorily paste the fingertip so as to wrap around the fingertip, which has conventionally been difficult to paste. Is possible.

The first-aid bandage of the present invention is not limited to the above-described embodiment, but may be any of a variety of other types of bandages other than a gown-shaped first-aid bandage as shown in FIG. Needless to say, the present invention can be applied to emergency bandages of various shapes corresponding to places, and various changes can be made without departing from the gist of the present invention.

[0025]

According to the above-mentioned emergency bandage of the present invention,
Various excellent effects as described below can be obtained.

(I) According to the invention of claim 1 of the present invention, the net does not directly touch the skin surface, and the smooth inner film touches the skin surface. In particular, it is possible to reduce the feeling of roughness due to the mesh of the net when the object is touched by being attached to a fingertip or the like, and it is possible to significantly reduce unpleasant feeling of discomfort.

(II) According to the invention of claim 1 of the present invention, a net for imparting required toughness to a base material can be made tough with a sufficiently large heat-sealing area through voids in the net. The adhesive layer sandwiched between the two bonded films and formed on the back surface of the base material is well formed on the entire back surface of the inner film without inclusions, and directly adheres to the net. Since it does not act on the skin surface, it is possible to prevent a problem that a part of the adhesive layer or the net is separated and remains on the skin surface when the base material is peeled off from the skin surface.

(III) According to the invention as set forth in claim 2 of the present invention, the base material is folded back at the constricted portion while the vicinity of the middle portion in the longitudinal direction of the pad is aligned with the fingertip, and one end of the base material is put on the finger Since the other end can be stuck to the back of the finger on the ventral side, and the side of the base that protrudes outward in the width direction of the finger can be folded inward and the base can be stuck so as to wrap around the fingertip. In addition, it is possible to satisfactorily attach to a fingertip, which has conventionally been difficult to attach.
