Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical patch such as a first aid bandage or an adhesive sheet for skin patch.

[0002]

2. Description of the Related Art There are many types of first-aid bandages that are directly applied to the skin of a patient (user). A general adhesive bandage is an absorbent body that touches a wound, a tape base material fixed to the absorbent body, a release paper attached to the surfaces of the absorbent body and the tape base material, and a wrapping paper that surrounds the entire body. Composed of.

As one type of adhesive plaster, a thin tape base material has been proposed for the purpose of improving moisture permeability and stretchability. As the tape substrate becomes thinner, it becomes difficult to handle. That is, it becomes difficult to keep the posture of the tape substrate itself flat during use, and the ease of mounting is impaired. Therefore, a structure has been proposed in which the tape base material is supported by a support film having high rigidity, and the support film is peeled off from the tape base material at the time of mounting.

[0004]

However, when the support film adhered to the tape base material is peeled off after the adhesive bandage is applied to the skin, the tape base material (the main bandage body) is removed from the skin.
Often come off together.

The present invention has been made in view of the above situation, and an object thereof is to provide a bandage capable of easily and smoothly peeling a supporting film supporting a thin tape base material from the bandage body. And

[0006]

In order to achieve the above object, the adhesive plaster according to claim 1 is an absorber that comes into contact with an affected area of a user; a film that fixes the absorber to the skin of the user. A tape-like base material; a film having a hardness higher than that of the tape base material and supporting the tape base material on the surface opposite to the absorber, and a support film that is peeled from the tape base material during use. Is equipped with. And
A slit having a predetermined length is formed at an end portion of the support film along a peeling direction from an outer edge portion in the peeling direction of the support film.

According to the invention described in claim 1, the support film can be easily and smoothly peeled off from the main body of the plaster. That is, the presence of the slits triggers the peeling of the support film from the tape base material. The support film can be smoothly peeled off as it is once it begins to peel off. If there is no slit, the trigger for peeling cannot be grasped and the supporting film often peels together with the tape substrate.

In the bandage according to claim 2 of the present application, a plurality of the slits are formed symmetrically and intermittently with respect to the center line along the peeling direction of the support film.
With such a configuration, the support film can be smoothly peeled off without twisting the support film and the tape base material.

In the bandage according to claim 3 of the present application, stopper means for dispersing the force applied to the site is provided at the end of the slit. This makes it possible to prevent the film from tearing at the end of the slit when the support film is peeled off.

Here, as the stopper means, as described in claim 4, a tape-shaped member fixed to the end portion of the slit can be used. If the tape of another member is used, the tape can be attached after the production of the plaster main body is completed, and the degree of freedom of the production process is increased.

In the bandage according to a fifth aspect, the stopper means is a circular hole which is formed continuously with the slit and has a diameter wider than the width of the slit. If such a configuration is adopted, the stopper means can be formed at the same time when the slit is formed, so that the manufacturing process can be simplified. Further, since no separate member is provided, it is possible to prevent the thickness of the entire bandage from increasing.

In the adhesive plaster according to the sixth aspect, the stopper means is another arc-shaped slit formed at the end portion of the slit and surrounding the end portion. In this case, since no separate member is provided, it is possible to prevent an increase in the thickness of the entire bandage. Further, compared with the case where the slit is formed continuously, there is an advantage that the force applied to the end portion of the slit is easily dispersed.

The bandage according to claim 7 of the present application is an absorber that comes into contact with an affected area of a user; a film-shaped tape base material that fixes the absorbent body to the skin of the user; and the tape base material. A film having a higher hardness and supporting the tape base material on the surface opposite to the absorber, which is peeled from the tape base material during use; and partially adhered to the support film. A first wrapping paper peeled from the tape base material together with the support film; a release paper provided on the side of the affected part of the absorber opposite to the tape base material; fixed to the release paper, A second wrapping paper that is peeled from the absorber is provided together with the release paper. Then, a slit of a predetermined length is formed along the peeling direction from the peeling direction outer edge portion of the supporting film in the region other than the bonding portion with the first wrapping paper at the end of the supporting film. .

According to the invention described in claim 7, the support film can be easily and smoothly peeled off from the adhesive bandage body, as in the invention of claim 1. That is, the presence of the slits triggers the peeling of the support film from the tape base material. The support film can be smoothly peeled off as it is once it begins to peel off. If there is no slit, the trigger for peeling cannot be grasped and the supporting film often peels together with the tape substrate.

Further, since the slit provided in the support film is formed in a region other than the bonding portion with the first wrapping paper, the support film can be effectively peeled off.

Furthermore, since the support film and the first wrapping paper are fixed and the release paper and the second wrapping paper are fixed, the bandage can be used very easily. That is, when the second wrapping paper is first peeled from the tape base material, the release paper is also peeled together with the wrapping paper. Next, when the adhesive surface of the absorber and the tape base material is applied to the affected area of the user and then the first wrapping paper is peeled off, the support film is also peeled off together with the wrapping paper. In this way, the operability (usage method) is simplified, and the dust after mounting is also the same as that of the first and second wrapping paper.
It becomes a piece and is easy to dispose.

In the bandage according to claim 8 of the present application, there are a plurality of adhesion positions between the support film and the first wrapping paper, and they are intermittently set in a direction orthogonal to the peeling direction of the support film. Has been done. With such a configuration, it is possible to perform a smooth peeling operation without tilting the support film in the direction orthogonal to the peeling direction.

According to the invention described in claim 9, a plurality of slits of the support film are formed symmetrically and intermittently with respect to the center line along the peeling direction, and the adhesion position of the support film and the first wrapping paper. Is at least the end on the peeling start position side of the support film, and is arranged outside the slits on both edge (side) sides along the peeling direction of the support film, so that the support film is a tape substrate. It can be peeled off evenly from the edge. That is, in addition to the effect of claim 8, the support film can be peeled off more smoothly and reliably.

According to the tenth aspect of the present invention, the supporting film and the first wrapping paper are adhered to each other at positions that do not overlap the slits and are not adjacent to each other with the slits interposed therebetween. There can be multiple triggers for peeling off the film, and the support film can be peeled off more reliably.

In the bandage according to claim 11 of the present application, the adhesion position between the support film and the first wrapping paper continuously extends in the vicinity of both edges along the peeling direction of the instruction film. I am trying. With such a configuration, when the support film is peeled off, it is easy to pull the film straight up.

In the bandage according to claim 12 of the present application, the adhesive force between the support film and the tape base material is larger than the adhesive force between the tape base material and the release paper, and the tape base material. And is set to be smaller than the adhesive force with the user's skin. With such a setting, it is possible to accurately perform the operation of peeling the release paper and the operation of peeling the support film. That is, it is not necessary that the release paper and the tape base material be adhered to each other with a strong adhesive force, and it is preferable that they can be peeled off relatively easily. On the other hand, the tape base material needs to be adhered to the user's skin with a relatively strong adhesive force. Otherwise,
This is because when the support film is peeled off, the tape base material is also peeled off together.

In the adhesive plaster according to claim 13 of the present application, the first wrapping paper is formed of a material having transparency so that the inside of the adhesive plaster can be seen. By making the wrapping paper on the upper side transparent, it becomes possible to accurately attach the bandage to the affected area while confirming the position of the bandage.

In the bandage according to claim 14 of the present application, as in the case of claim 2, a plurality of the slits are formed symmetrically and intermittently with respect to the center line along the peeling direction of the support film. To be done. With such a configuration, the support film can be smoothly peeled off without twisting the support film and the tape base material.

In the adhesive plaster according to claim 15 of the present application, as in the case of claim 3, stopper means is provided at the terminal end of the slit to disperse the force applied to the site. This makes it possible to prevent the film from tearing at the end of the slit when the support film is peeled off.

In the adhesive plaster according to claim 16 of the present application, as in the case of claim 4, the stopper means can be a tape-like member fixed to the end portion of the slit. If the tape of another member is used, the tape can be attached after the production of the plaster main body is completed, and the degree of freedom of the production process is increased.

In the bandage according to claim 17, as in the case of claim 5, the stopper means is a circular hole which is formed continuously with the slit and has a diameter wider than the width of the slit. If such a configuration is adopted, the stopper means can be formed at the same time when the slit is formed, so that the manufacturing process can be simplified. Further, since no separate member is provided, it is possible to prevent the thickness of the entire bandage from increasing.

In the adhesive plaster according to claim 18, as in the case of claim 6, the stopper means is formed in the end portion of the slit and has an arc shape other than the end portion. And the slit. In this case, since no separate member is provided, it is possible to prevent an increase in the thickness of the entire bandage. Further, compared with the case where the slit is formed continuously, there is an advantage that the force applied to the end portion of the slit is easily dispersed.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described by taking an emergency bandage applied to an affected area of a user as an example. In addition, in this specification, for convenience of description, the invention has a name of “adhesive plaster”, but the present invention can be applied to variously packaged medical patch materials which are individually packaged.

FIG. 1 is a plan view showing an emergency bandage 10 according to an embodiment of the present invention. FIG. 2 is a sectional view taken along line II of FIG. FIG. 3 is a cross-sectional view showing a state (use state) in which the adhesive bandage according to the example is attached to the affected area.
The first-aid bandage 10 according to the present embodiment is a wrapping paper 1 with two front and back sheets.
2 (12a, 12b), the plaster main body 14, and the support film 20. The adhesive bandage main body 14 includes an absorber 16 that contacts the affected area, a tape base material 18 that fixes the absorber 16 to the user's skin, and a release paper 22 that is in close contact with the absorber 16.

The support film 20 has a tape substrate 1 on one side.
8 and the other surface is fixed to the wrapping paper 12a.
Then, the wrapping paper 12a and the support film 20 operate integrally. That is, when the wrapping paper 12a is peeled off from the bandage main body 14, the support film 20 is also peeled off together. On the other hand, the wrapping paper 12b and the release paper 22 also operate integrally. That is, the wrapping paper 12b
Is peeled off from the adhesive plaster body 14, the release paper 22 is also peeled off together.

The tape base material 18 can be molded from a resin film. Examples of the resin include vinyl chloride, polyacrylic acid such as PMMA (polymethylmethacrylate), polymethacrylic acid derivative, polyester,
Polyurethane or polyolefin resin can be used. The thickness of the tape base material 18 is, for example, 5 μm to 6 μm.
It is preferably 0 μm. In the present embodiment, the tape base material 18 is thinned for the purpose of improving moisture permeability and stretchability.

A tape adhesive (not shown) is applied to the surface (affected area side) of the tape base material 18. Examples of tape adhesives include acrylic adhesives, rubber adhesives, cellulose adhesives, PVA (polyvinyl alcohol)
In addition to the system adhesives, polyamino acid gels such as gelatin, polyglutamic acid, and polylysine can be used. The adhesive force when it is attached to the user's skin and peeled off immediately after is, for example, 0.5 to 15 N / 15 mm. Preferably,
2 to 10 N / 15 mm. The measurement of the adhesive force described above and below is based on JIS Z0237 180 degree peeling method.

The absorber 16 is fixed to the tape base material 18 by the above-mentioned tape adhesive. The body fluid absorbing portion (near the center) of the absorber 16 is a laminate of hydrophilic fibers such as cotton, rayon, acetate, or an absorbent acrylic resin, PVA, gelatin, cellulose, starch, polyglutamic acid, polylysine, etc. The polyamino acid-based resin can be used. In addition, in order to prevent the body fluid leached in the affected area and the absorber 16 from sticking together,
The surface of the absorption site may be covered with a net made of polyolefin resin.

The release paper 22 is a polyolefin film,
Alternatively, a polyolefin resin laminated paper coated with curable silicone can be used. The release paper 22 can be fixed to the wrapping paper 12b with an adhesive or heat seal. Alternatively, the wrapping paper 12
By pattern printing on the surface (inner surface) of b,
The release paper 22 can also be configured. The peel strength (adhesive force) between the tape adhesive and the release paper 22 is, for example, 0.01
N / 15 mm to 0.5 N / 15 mm. Preferably, it is 0.03 N / 15 mm to 0.2 N / 15 mm.

The wrapping paper 12a on the front side has a total light transmittance of 20% (JIS so that the adhesive plaster can be confirmed from the outside.
It is preferable to use a material having high transparency of K7105) or higher. For example, polyethylene, polypropylene,
A composite film such as polyester, nylon, polyethylene terephthalate, or an OPP (biaxially oriented polypropylene) film can be used. By making the wrapping paper 12a transparent, it becomes possible to accurately attach the bandage to the affected area while confirming the position of the bandage. As the lower wrapping paper 12b, the same film resin as the upper wrapping paper 12a or paper laminated with the resin can be used.

At least one of the opposing surfaces of the wrapping papers 12a and 12b is coated with a rubber resin, and 1N / c
The package is sealed by applying a pressure of m ² or more. When applying the rubber resin, the edges in the peeling direction (left and right direction in FIG. 1) are not adhered.
As a result, the wrapping paper 12a, 12b from the non-adhesive part
It becomes easy to peel off.

The support film 20 has a higher hardness than the tape base material 18, and can be formed of, for example, a polyolefin-based or polyester-based resin. The support film 20 and the tape base material 18 can be fixed by the interaction between molecules by applying heat at a low temperature. The adhesive force between the tape base material 18 and the support film 20 at that time is preferably smaller than the adhesive force between the skin and the tape adhesive. If the adhesive strength between the tape base material 18 and the support film 20 is larger than the adhesive strength between the skin and the tape adhesive, the tape base material 18 is likely to peel off from the skin when the support film 20 is peeled off. is there.

FIG. 4 is a plan view showing the structure of the support film 20. The support film 20 includes the film 20.
Peeling direction (longitudinal direction of the plaster, hereinafter simply "peeling direction")
Two slits 24, 26, 28, 30 are formed at both ends from the outer edge of the slit along the peeling direction. The slits 24 and 26 and the slits 28 and 30 are arranged symmetrically and intermittently with respect to the center line C along the peeling direction. The position in the direction orthogonal to the peeling direction is, for example, 2 mm to 20 mm from the end. In addition,
The adhesive bandage 10 according to the present embodiment has a structure that can be peeled from both left and right directions.

In FIG. 4, reference numerals 32, 34, 36 and 3
Reference numeral 8 indicates a bonding position between the wrapping paper 12a and the support film 20. As shown, the slit 2 on the support film 20
4, 26, 28, 30 are formed in regions other than the bonding portions 32, 34, 36, 38 with the first wrapping paper 12a. Thereby, the support film 20 can be effectively peeled off.

The support film 20 is preferably adhered to the wrapping paper 12a only at a part of the peeling start side end. This facilitates the peeling of the support film 20 from the tape base material 18. Further, preferably, the adhesion position between the support film 20 and the wrapping paper 12a includes at least the end on the peeling start position side and is provided near both ends (edges) in the direction orthogonal to the peeling direction. That is, at a minimum,
It is important to form them at the two corners on the peeling start position side. In the case of the present embodiment, since the peeling start positions are on the left and right sides of the drawing, the bonding positions of the support film 20 and the wrapping paper 12a are at least the four corners of the support film 20.
