DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency bandage provided with an ointment.

[0002]

2. Description of the Related Art An adhesive layer is formed by laminating an adhesive layer on one side of a synthetic resin foam sheet, forming a concave portion on the adhesive layer side, and providing an ointment or salve containing salicylic acid in the concave portion. This is known from Japanese Utility Model Laid-Open No. 4-27912. Conventional emergency bandages use a gauze impregnated with a germicide and dried.

[0003]

In the bandage described in the above publication, the ointment is directly placed in the concave portion formed in the foamed sheet.
The ointment penetrates into the foam sheet through the pores and loses weight.
In addition, since the ointment has fluidity, the ointment leaches between the adhesive layer and the release paper during storage, or leaches between the skin and the adhesive layer during use. Reduces adhesive strength,
Drops off during use. In addition, the conventional first-aid bandage does not have a bactericidal effect because the bactericide is in a dry state, and there is also a problem that it sticks to the wound and causes pain.

The present invention solves the above-mentioned conventional problems, and provides an emergency bandage with an ointment, which has an excellent protective effect on an affected area and a remarkable medicinal effect and can prevent weight loss of the ointment. It is an object of the present invention to provide an ointment-equipped emergency bandage which does not leach between the agent layer and the release paper and does not allow the ointment to flow to a site other than the affected part during use.

[0005]

According to a first aspect of the present invention, there is provided an emergency bandage with an ointment, wherein a concave portion is formed on one surface of a foam sheet having closed cells and contains at least one kind of a bactericide for antibiotics or an antibiotic. An ointment is impregnated with a fibrous substance and loaded into the concave portion, an adhesive layer is provided on the foam sheet surface excluding the concave portion, and a release sheet is laminated on the adhesive layer surface.

According to a second aspect of the present invention, there is provided an emergency bandage with an ointment, wherein a concave portion is formed on the adhesive layer side of a foam sheet provided with an adhesive layer on one surface, and an isolating film is laminated on the surface of the concave portion. An ointment containing at least one of a bactericide for antibiotics or an antibiotic is loaded in the concave portion by impregnating the fibrous substance, and a release sheet is laminated on the surface of the adhesive layer excluding the concave portion. .

The first-aid bandage of the present invention is intended to protect wound sites and treat purulent diseases, and includes a bactericidal agent for the outer skin such as benzalkonium chloride and acrynol, and / or a sulfa agent, tetracycline hydrochloride, penicillin and the like. An ointment containing a purulent agent or the like is used. Ointment base is oily,
Emulsion type or water-soluble type may be used.

For the adhesive layer, an acrylic adhesive used in general plasters can be used.

The release sheet is made of paper such as kraft paper, glassine paper, high-quality paper, etc., on which a polyethylene resin is laminated on a base material surface and a silicone release layer is provided on the polyethylene resin surface, polypropylene, polyester, chloride, etc. A synthetic resin sheet of vinyl or the like is used, and a sheet whose surface is release-treated with a silicone resin, a fluororesin, or the like is used as necessary.

The release sheet is preferably divided at the surface of the adhesive layer so that the release sheet is easily peeled off when used. When the release sheet is divided in this way, the division should avoid the concave portion where the ointment is loaded. It is.

The foam sheet used for the ointment emergency bandage according to the first aspect is composed of closed cells, and the resin is particularly preferably low-density polyethylene, and polypropylene, linear low-density polyethylene and ethylene-vinyl acetate are preferred. A mixture of a polyolefin resin such as a polymer can also be used. Open cells may be mixed in the foamed sheet, but preferably 80% or more are closed cells.
The above-mentioned foamed sheet is preferably crosslinked, because the bubbles are fine and uniform and the strength is excellent. Further, the expansion ratio of the foamed sheet is preferably in the range of 20 to 40 times from the viewpoint of followability to skin expansion and contraction, feel to the skin, and the like.

An adhesive layer is provided on one surface of the foamed sheet, and a concave portion for loading an ointment is formed on one surface, but no adhesive layer is provided in the concave portion. In order to form the concave portion where the adhesive layer is not provided, for example, an adhesive is applied to one surface of the release paper subjected to the release treatment and dried, and the adhesive is removed together with the release paper by punching out the concave portion to the size of the release paper. When the release paper is removed after laminating the release paper on the foam sheet, the part where the release paper is punched becomes a part without the adhesive. When the foamed sheet in this portion is heated and pressed by hot stamping, a concave portion without an adhesive is formed.

An ointment containing at least one of a bactericide for skin or an antibiotic is impregnated with a fibrous substance in a concave portion formed on one surface of the foamed sheet. Polyester, cellulose, acrylic,
Examples include synthetic resin fibers such as polyolefins and polyvinyl alcohols, and natural fibers such as cotton, hemp, and wool. These fibers may be used alone or as a mixture of two or more kinds, and the form thereof may be an absorbent cotton-like one in which the fibers are simply gathered and entangled, a nonwoven fabric or a woven one.

When the ointment is oily, it is particularly preferable to use a hydrophilic substance such as a cellulosic substance as the fibrous substance, since the cellulosic fibers can absorb the exudate of the affected part of the suppuration.

When an ointment is impregnated with a fibrous substance, its fluidity is limited by the viscosity of the ointment itself and its adhesion to fibers. As a result, the ointment is prevented from leaching between the adhesive layer and the release sheet during storage and between the adhesive layer and the skin during use. Therefore, even an ointment having a lower viscosity than usual can be concentrated on the affected area, and the plaster does not fall off naturally during use.

Further, by laminating the release sheet on the surface of the adhesive layer, the ointment does not flow out during storage, and various bacteria and dust are not mixed into the ointment, so that the adhesive layer can be protected.

The foamed sheet used in the ointment-equipped emergency bandage according to the second aspect may be closed cells, open cells, or a mixture of both.
Therefore, a foamed sheet of a polyolefin resin, a vinyl chloride resin, a polyurethane resin, an acrylic resin, or the like can be used. In addition, when an open-cell foam sheet is used, air permeability can be obtained, so that it can be used comfortably without stuffiness even when used for a long time. The expansion ratio of the foamed sheet is preferably in the range of 15 to 35 times from the viewpoint of followability to skin expansion and contraction, feel to the skin, and the like.

In order to form a concave portion on the adhesive layer side of the foamed sheet, an isolating film having the same size as the surface of the concave portion to be formed is placed on the adhesive layer surface, and heated and pressed by hot stamping from above the isolating film. A concave portion in which the isolation film is adhered to the inner surface can be formed in the foam sheet.

Any isolation film can be used as long as it is made of a thermoplastic resin, but is chemically inert.
A film that easily fits into a concave curved surface is preferable, and a film of a polyolefin resin is preferable. In addition, metal foil such as aluminum, or a film obtained by vacuum-depositing a metal on the above film can also be used. The isolating film may be provided only on the inner surface of the concave portion, but a flange-shaped portion may be formed from the periphery of the concave portion to the outside, so that the pain caused by the end of the isolating film sticking to the skin may be reduced. There is no feeling.

[0020] The ointment used for the emergency bandage with ointment is
A fibrous material similar to that of claim 1 is impregnated and loaded into the recess. According to the ointment with bandage according to claim 2, wherein composed as described above, the ointment its fluidity adhesion to the viscosity and the fiber having been impregnated in the fiber material ointment itself is limited. As a result, the ointment is prevented from leaching between the adhesive layer and the release sheet during storage and between the adhesive layer and the skin during use. Therefore, even an ointment having a lower viscosity than usual can be concentrated on the affected area, and the plaster does not fall off naturally during use. or,
Even if the foamed sheet is open-celled, the ointment does not pass through the isolation film, and the ointment does not leach out of the concave portion into the foamed sheet and lose weight. Further, since the ointment and the adhesive layer do not come into contact with each other by the isolating film, the ointment does not lose its efficacy due to the migration of the ointment component to the adhesive layer.

[0021]

According to the first aspect of the present invention, since the ointment is impregnated with a fibrous substance, the fluidity of the ointment itself is limited by the viscosity and the adhesive force to the fiber.
As a result, the ointment is prevented from leaching between the adhesive layer and the release sheet during storage and between the adhesive layer and the skin during use. Therefore, even an ointment having a lower viscosity than usual can be concentrated on the affected area, and the plaster in use does not fall off naturally.

According to the second aspect of the present invention, the ointment is impregnated with a fibrous substance, and the fluidity of the ointment itself is limited by the viscosity of the ointment itself and the adhesive force to the fiber.
As a result, the ointment does not leach between the adhesive layer and the release sheet during storage, and does not leach between the adhesive layer and the skin during use, and the adhesive bandage during use does not drop off naturally.
Further, even if the foamed sheet is open cells, the ointment does not permeate the isolation film, and does not leach out from the concave portion to the foamed sheet to reduce the weight. Further, since the ointment and the adhesive layer do not come into contact with each other by the isolating film, the ointment does not lose its efficacy due to the migration of the ointment component to the adhesive layer.
