As mentioned above, the conventional technology for the purpose of blocking UV rays is to simply blend UV blockers into pressure-sensitive adhesive drug-containing adhesive layers such as poultices and gel preparations, add inorganic fillers, and breathability. The purpose of use, such as application and UV blocking, is different, but it contains UV blocking substances such as zinc oxide and titanium oxide over the entire surface of the base film of medical adhesive tape. It did not disclose an ultraviolet blocking technique in an emergency bandage in which a pad such as a cloth, non-woven fabric, or knitted fabric was stuck and a drug was carried on the pad.
For the purpose of avoiding wound healing delay due to UV exposure in the emergency bandage carrying the drug, or preventing alteration of the drug due to UV light, an ultraviolet blocking agent is applied over the entire surface of the adhesive tape as the base film. In order to obtain a proper moisturizing effect, it is not only costly to manufacture, but also in the case of insufficient breathability, it causes rashes on wounds and delayed healing. There was a concern that would arise.
Furthermore, in the emergency bandage, the pad is brought into contact with the wound part, so it is not necessary to check the state of the wound part through the base film of the affected part, and avoids the uncomfortable feeling in sticking to the skin surface. In order to achieve this, it is sufficient to have the light transmittance that is achieved with the base film used in ordinary emergency bandages, and it is necessary to have a transparency close to the skin color and not to cause a sense of incongruity. It is not satisfactory as a technique to be applied to an emergency bandage that has to be provided at a low cost because it is complicated and expensive to manufacture while maintaining the visible light permeability. There wasn't.

  The present invention has been made in view of such problems, and the object of the present invention is to attach a pad part to the central part of the adhesive surface of the adhesive layer on the upper surface of the support, and the pad part of the adhesive layer is In the emergency adhesive bandage formed by releasably attaching the release film to the upper surface of the part that is not attached, without blending it into the drug-containing pressure-sensitive adhesive layer such as the pap plaster or the base film, By applying a device to arrange a layer containing an ultraviolet blocking agent in emergency bandages, it is possible to easily and inexpensively effectively suppress wound healing due to ultraviolet exposure, pigmentation, etc., and carry it on a pad. An object of the present invention is to provide an emergency bandage that can effectively prevent alteration or the like of drugs due to ultraviolet rays.

  Under such circumstances, as a result of intensive research to achieve the above object, the present inventor has found that an emergency adhesive bandage, in particular an emergency adhesive bandage with an ointment, includes a film kneaded or coated with an ultraviolet blocking agent between the pads. , Intervene between the pad and cushion material, between the pad part and the adhesive surface of the adhesive layer, knead UV blocker into the adhesive body of the adhesive layer, coat the adhesive surface of the adhesive layer, and support The inventors have found that the above problem can be solved by providing a layer containing an ultraviolet blocking agent, such as coating on the body, and have completed the present invention.

It is about.

According to invention of Claim 1, a pad part is stuck on the adhesive face center part of the adhesion layer of a support body upper surface, and it is a mold release on the upper surface of the part to which the said pad part of the said adhesion layer is not stuck. In the emergency bandage formed by sticking the film so that it can be peeled off, a layer containing an ultraviolet blocking agent is disposed, so that the entire surface of the substrate film does not contain an ultraviolet blocking agent, and a poultice In addition, the pressure sensitive adhesive layer plaster containing a drug, such as a gel preparation, does not contain an ultraviolet blocking agent, and has a moderate breathability of conventional general emergency bandages and emergency bandages with ointments, While maintaining properties such as moisture permeability and light transmissivity, UV exposure to wounds is effectively suppressed, healing delay of wounds is effectively suppressed, and alteration due to UV exposure of drugs is also effectively suppressed. can do.
In particular, UV-A, which is said to promote melanogenesis and promote skin aging when exposed to skin with a wavelength of 400 to 320 nm as an ultraviolet blocker, and acute inflammation and immunosuppression when exposed to skin with a wavelength of 320 to 290 nm. Because it is a layer containing UV-B UV-blocking agent (UV-scattering agent or UV-absorbing agent), which is said to be one of the causes of skin cancer, stains and freckles, the effect of wounds It is possible to promote general healing and suppress drug alteration.

In particular, as an ultraviolet blocking agent, titanium oxide, zinc oxide, which is an ultraviolet scattering agent blocking by scattering ultraviolet rays, or a processed product thereof such as titanium oxide or zinc oxide-based ultrafine particles is used. The effect on the skin can be effectively blocked by reducing the influence on the skin, and in combination with the bactericidal effect of zinc oxide and titanium oxide, an excellent healing promotion effect of the wound is exhibited.
In particular, by setting the ultraviolet ray cut rate at a wavelength of 380 to 290 nm to 95% or more, it is possible to reliably suppress the ultraviolet ray exposure to the drug impregnated in the pad portion and the affected surface.

  Since the pad portion uses two or more pads or an emergency bandage in which a pad and a cushion material are laminated, a layer containing an ultraviolet blocking agent, for example, a film kneaded or coated with an ultraviolet blocking agent Can be placed not only below the pad part (below the pad or cushion material, below the pad part covered with the net, etc.) but also between two or more pads or between the pad and cushion material. It can be manufactured in the same manufacturing process as a conventional emergency bandage, and does not cause a significant increase in manufacturing cost. In the case of an emergency bandage with an ointment with an ointment layered on the upper surface of the pad part, penetration of the ointment below the pad part includes two or more pads, a pad and a cushioning material, and a UV blocker. It is still a preferred embodiment because it can be effectively suppressed by the layer. Furthermore, when the cushioning material is disposed below the pad, it becomes an appropriate pressing force rich in elasticity, and the wound healing promotion effect can be enhanced without damaging the wound opening.

  Furthermore, the UV-blocking agent-containing layer is transparent or skin-colored, or is colored in other colors to an inconspicuous extent (slightly colored). Thus, even if it is applied to the skin, the applied part is not conspicuous, and the advantages of the emergency bandage provided with a layer containing an ultraviolet blocking agent can be enjoyed without impairing the beauty.

  In addition, by using an emergency plaster with an ointment with an ointment layered on the upper surface of the pad of the pad part, the problems of general emergency adhesive plaster and emergency adhesive bandages containing medicinal solution capsules are solved, and an ultraviolet blocking agent is used. By disposing the layer to be contained, it is possible to ensure the healing of the wound part by exposure to ultraviolet rays and to effectively suppress the alteration of the ointment.

By adopting a structure in which an ointment protective cover formed by forming a blister section having a dome-shaped cross section is releasably attached to the adhesive surface of the adhesive layer, avoiding the wound part and ointment from exposure to ultraviolet rays, In addition to the above-mentioned advantages such as permeation suppression, contact with the outside air can be avoided, and the use of capsules etc. can be avoided, so that it is possible to effectively prevent deterioration of the ointment and reduction of the effective amount due to transfer. it can.
In the present invention, the ointment protective cover is formed into a blister section having a dome-shaped cross section by bulging and forming the central section upward in a gentle arc shape, or further blister section Are formed in a plane rectangular shape, and both side wall portions on the long side thereof are formed as standing wall portions inclined in a direction approaching each other upward from the lower end, or further, an ointment protective cover is provided. A blister on a flat rectangle in which the pad portion with the ointment layered on the upper surface is formed on the adhesive surface of the rectangular adhesive layer, and the four peripheral walls are formed higher than the thickness of the pad layered with the ointment The bulge is formed at the center, and is detachably attached to the pad to cover the pad with the blister. Bulging toward the parallel ridges upwardly directionally, by as those formed, in addition to the advantages, it is possible to firmly prevent such accidental crushing when carried.

  Further, according to the present invention, in the emergency bandage, the film containing an ultraviolet blocking agent is used as the layer containing the ultraviolet blocking agent, and the film is formed between the adhesive surface of the adhesive layer and the pad portion. It is placed between the adhesive surface and the net covering the pad part or in the pad part, and with the same manufacturing method as the conventional emergency bandage, it simply and reliably achieves UV blocking. In addition, it is possible to avoid the healing delay of the wound due to the exposure to ultraviolet rays, and to effectively suppress the alteration of the drug due to the exposure to ultraviolet rays, so that the drug can effectively act on the affected area. In addition, this technique of kneading or coating an ultraviolet blocking agent on a film can be easily colored by adding other pigments and dyes, and can be colored to other colors to such an extent that it is not noticeable. It becomes easy. Furthermore, especially in the emergency bandages with ointments, the usual bandages for emergencies and emergency bandages with liquid capsules have been used to eliminate the problems of damaging the wounds, splashing liquids, and expensiveness, and the use of ointments due to UV exposure. It is possible to effectively suppress alteration.

  According to the invention of claim 2, by using a perforated film as a film kneaded with or coated with an ultraviolet blocking agent, in addition to the effect of claim 1, the air permeability and moisture permeability are sufficient. In any emergency bandage, especially an emergency bandage with ointment, it can be safely applied for a long time without causing rash.

  According to invention of Claim 3, the film which kneaded or coated the ultraviolet blocker was arrange | positioned in the lower surface of a pad part, and the circumference | surroundings of the film which kneaded or coated the pad part and the ultraviolet blocker were carried out with the net | network. In addition to the advantages of claim 1, in addition to the advantages of claim 1, even if the pad portion is displaced or two or more pads, or a pad and a cushion material are used, they are separated. Thus, it is possible to effectively prevent the effective treatment of the affected area from being hindered. In particular, in emergency bandages with ointment, since the drug contacts the affected area via the net, it is possible to prevent adhesion between the pad and the wound opening, without damaging the wound part during peeling, and alteration of the drug Can also be suppressed, and the drug can effectively act on the affected area.

  According to the invention of claim 4, the film kneaded with or coated with the ultraviolet blocking agent is a perforated film, and the air holes of the perforated film are blocked by contact with the adhesive surface of the adhesive layer in the lower layer. By providing a diffusing material for preventing the above problem, it is possible to ensure air permeability and achieve the same effect as that of claim 3 in addition to the advantage of claim 1.

  According to invention of Claim 5, the circumference | surroundings of a pad part are coat | covered with a net | network, and it fixes by heat welding, A plane a little smaller than a pad part between the lower surface of this net | network covering pad part and the adhesion surface of an adhesion layer. In addition to the advantage of claim 1, the same effect as in claim 3 can be achieved by disposing a film kneaded or coated with the ultraviolet blocking agent.

  According to the invention of claim 6, by disposing a film kneaded or coated with an ultraviolet blocking agent between two or more pads or between a pad and a cushion material, Not only can UV exposure be cut, but the underlying pad or cushioning material will act as an appropriate pressing force with elasticity against the wound, effectively promoting wound healing by UV exposure, It is possible to effectively suppress the alteration of the drug due to exposure to ultraviolet rays and to cause the drug to effectively act on the affected area. In addition, it has a structure that can ensure air permeability, rather than overlapping the pads or simply overlapping the pads and the cushioning material, and is more effective when using a perforated film. In particular, in the emergency bandage with ointment, in addition to the above-mentioned advantages, it is possible not only to effectively prevent the ointment layered on the pad part from penetrating below the pad part, but also due to ultraviolet exposure. Alteration of the ointment can be prevented.

  According to invention of Claim 7, a pad part is stuck on the adhesive face center part of the adhesion layer of a support body upper surface, and a release film is applied to the upper surface of the part to which the said pad part of the said adhesion layer is not stuck. In the adhesive bandage for emergency use, which is attached in a peelable manner, as a layer containing an ultraviolet blocking agent, by taking a configuration in which an ultraviolet blocking agent is kneaded into the adhesive body of the adhesive layer on the upper surface of the support, It can be manufactured simply by changing the adhesive layer as if it were a conventional emergency bandage, and it can also be given appropriate breathability and moisture permeability to the adhesive layer. In the same manner as in the case of claim 1 in which a layer is provided as a film, it is possible to reliably achieve UV blocking, avoid delay in healing of the wound due to UV exposure, and effectively suppress alteration of the drug due to UV exposure. You It is possible, it is possible to effectively act the drug to the affected area. In addition, this technique of kneading an ultraviolet blocking agent into an adhesive body can be easily colored by adding other pigments and dyes, and can easily be transparent or skin-colored or slightly colored. In particular, in the emergency bandage with ointment, as in the first aspect of the invention, the problems such as damage to the wound, spraying of the liquid, and high cost of the normal bandage for emergency and the bandage for emergency with the liquid medicine capsule are solved. At the same time, it is possible to effectively suppress the alteration of the ointment due to exposure to ultraviolet rays by a simple production method.

  According to the invention of claim 8, in the emergency bandage according to claim 1, as the layer containing the ultraviolet blocking agent, the entire upper surface of the support is laminated with a film kneaded or coated with the ultraviolet blocking agent By using a film that has been kneaded or coated with an ultraviolet blocking agent before laminating the pressure-sensitive adhesive on the upper surface of the support, a normal pressure-sensitive adhesive is layered on the upper surface. Yes, it can be manufactured more easily than the partial laminating technique of claim 6 and can achieve the same effect as that of claim 7 in which an ultraviolet blocking agent is kneaded into the adhesive body of the adhesive layer. That is, as in the case of claim 1 in which a layer is provided as a film in which an ultraviolet blocking agent is kneaded or coated, it is possible to reliably achieve ultraviolet blocking and avoid healing of wound healing due to ultraviolet exposure, Since the alteration of the drug due to exposure to ultraviolet rays can be effectively suppressed, the drug can effectively act on the affected area. This technique of laminating a film kneaded or coated with an ultraviolet blocking agent can be easily colored by adding other pigments and dyes, and can easily be transparent or skin-colored or slightly colored. In particular, in the emergency bandage with ointment, as in the first aspect of the invention, the problems of ordinary emergency bandages and emergency bandages with drug capsules are solved, and the alteration of the ointment due to UV exposure is also effective. Can be achieved by a simple production method.

  According to the invention of claim 9, in the emergency bandage of the invention of claim 8, the film in which the ultraviolet blocking agent is kneaded or coated is formed as a perforated film, so that it is more effective than the emergency bandage of claim 8. There is an advantage that it is easy to ensure appropriate air permeability and moisture permeability.

  According to the invention of claim 10, the layer containing the ultraviolet blocking agent is disposed, and two or more pads are laminated, the ointment is applied on the upper surface of the upper layer pad, and the penetration of the ointment into the pad is prevented. There is provided an emergency bandage that also has a suppressing function. In particular, a more preferable embodiment of the emergency bandage with an ointment having a function of suppressing the penetration of such an ointment is an emergency bandage, an ultraviolet blocker in which the ultraviolet blocking agent is for UV-A and UV-B The agent is titanium oxide, zinc oxide, or an emergency plaster that is a processed product thereof, an emergency plaster that has an ultraviolet cut rate of 95% or more, and the UV-blocking agent-containing layer is transparent, skin-colored, or slightly colored An emergency bandage, an emergency bandage in which a film kneaded with or coated with an ultraviolet blocking agent is disposed between the adhesive surface of the adhesive layer and the pad portion (claim 11), and an ointment on the lower surface of the lower layer pad A film that suppresses the penetration of the drug and a film kneaded or coated with an ultraviolet blocking agent is disposed, and the upper layer pad, the lower layer pad, the film that suppresses the penetration of the ointment, and the ultraviolet ray Covering the periphery of the film in which the cutting agent is kneaded or coated with a net, heat-adhesive bandage (Claim 12), and penetration of the ointment between the upper layer pad and the lower layer pad A film to suppress, a film kneaded or coated with an ultraviolet blocking agent on the lower surface of the lower layer pad, an upper layer pad, a lower layer pad, a film to suppress the penetration of an ointment, and an ultraviolet blocking agent It is an emergency bandage (Claim 13), which is a kneaded or coated film coated with a net and fixed by heat welding (Claim 13).

Salicylic acid ultraviolet absorbers such as 2-ethylhexyl (octyl), benzophenone ultraviolet absorbers such as oxybenzone that absorbs UV-B to short wavelength UV-A, p-methoxycinnamic acid that absorbs UV-B 2 Cinnamic acid-based UV absorbers such as ethylhexyl (octyl), benzotriazole-based UV absorbers such as 2- (2-hydroxy-5-methylphenyl) benzotriazole, 2-ethylhexyl paramethoxycinnamate (octyl), 2-ethylhexyl salicylate And 2-ethylhexyl-2-cyano-3,3-diphenyl acrylate Cyanoacrylate-based ultraviolet absorbers, p-aminobenzoic acid, p-dimethylaminobenzoic acid octyl, ultraviolet absorber of salicylic acid homosalate and various.

  The “support” used in the present invention functions as a backing and backing member for an emergency bandage, and is a thin polyolefin film having moderate flexibility, stretchability, moisture permeability, breathability, light permeability, etc. A rectangular sheet piece having a fixed width and a fixed length made of a synthetic resin sheet, nonwoven fabric, woven fabric, paper, or the like, and as such a material, in particular, plasticized polyvinyl chloride, amorphous polyolefin Synthetic resins such as olefin resins, polyester resins, ethylene vinyl acetate resins, elastomer resins, copolymers of olefin resins and thermoplastic elastomers, and polymer alloys of olefin resins and thermoplastic elastomers are preferred. In particular, polyolefin resin, polyester resin, or polyolefin resin and thermoplastic elastomer Polymers are more preferred. The support is embossed and uniaxially stretched to give the properties desired as a support for emergency bandages, such as breathability, moisture permeability, strength, weather resistance, operability during application, and skin irritation. Those subjected to various processes such as biaxial stretching and annealing, and those containing various additives and fillers are preferably used. Examples of such additives include antioxidants, light stabilizers, heat stabilizers, antistatic agents, lubricants, flame retardants, pigments, and dyes, and fillers include calcium carbonate, calcium sulfate, and oxidation. Examples thereof include titanium, barium sulfate, magnesium hydroxide, and clay. Such materials are kneaded with various components to be blended with various kneaders, Banbury mixers, etc., heated and melt-kneaded with a single-screw or twin-screw extruder or the like to form resin pellets, and then formed into a film.

  The pressure-sensitive adhesive layered on the support is capable of being layered and held on the support, has a pressure-sensitive adhesive force that can be stuck to the adherend, and holds the pad portion attached. Restricted to adhesives that have a function, desirably good adhesiveness, maintain the adhesiveness without being significantly attenuated, and have safety that does not cause rash even if applied for a long time Acrylic adhesives, rubber adhesives, silicone rubber adhesives, vinyl ether adhesives, urethane adhesives, and the like can be used. In particular, when the ultraviolet blocking agent such as zinc oxide, titanium oxide, and their processed product is kneaded into the adhesive body of the adhesive layer in the ultraviolet blocking emergency bandage of the present invention, these blocking agents are easily and in large quantities. Adhesive resins that can be filled in are suitable, and specific examples include acrylic resins, urethane resins, and silicone resins.

  The “pressure-sensitive adhesive sheet” means a sheet composed of the support and the pressure-sensitive adhesive layer layered thereon, and the pressure-sensitive adhesive sheet in which an ultraviolet blocking agent is kneaded into the pressure-sensitive adhesive body of the pressure-sensitive adhesive layer is It is an important material for the UV-blocking emergency bandage with excellent invention.

The “film kneaded or coated with an ultraviolet blocking agent” used in the present invention means a film obtained by the following two production methods.
In the first production method, the ultraviolet blocking agent described above is mixed with a liquid dispersion such as an aqueous dispersion of a polyolefin resin such as a polyethylene thermoplastic resin, together with various additives, and an ultraviolet blocking agent or a combination thereof. After heating, kneading and forming into a film, it is cooled and solidified or crosslinked to give the film an ultraviolet blocking effect, or in a liquid dispersion such as an aqueous dispersion of a polyolefin resin such as a polyethylene thermoplastic resin. Then, various additives are blended, heated, kneaded, formed into a film, then cooled, solidified or cross-linked, previously formed as a film, and a developing solution containing an ultraviolet blocking agent or a combination thereof on one side of the film is calendered. Coating with a spreading method commonly used in the field, such as a roll method, to impart an ultraviolet blocking effect to the film It is carried out by. In addition, the production of a film coated with an ultraviolet absorber is carried out by emulsifying and dispersing the ultraviolet absorber in water and impregnating and adsorbing the film by dipping.
In addition, “kneading the ultraviolet blocking agent into the adhesive body of the adhesive layer” means that the ultraviolet blocking agent is added to a liquid dispersion such as an aqueous dispersion of the pressure sensitive adhesive together with various additives. This combination is blended, kneaded, layered on the support, dried, cooled, solidified, or cross-linked to give the UV-blocking effect to the adhesive sheet. Necessary for these dispersions and developing solutions. Additives added accordingly include cross-linking agents, softeners (plasticizers), dispersion stabilizers, tackifier resins, fillers and antioxidants.
Therefore, “kneading” means a state in which the ultraviolet blocking agent is incorporated into the film or the adhesive body so as to be contained after heating and kneading. It is not intended to limit.
Similarly, “coated” means a state in which an ultraviolet blocking agent is coated on a film or support so that it is laminated on the film or support through a coating operation. The manufacturing method which makes such a state is not limited.
In the second production method, an ultraviolet blocking agent is mixed with a polyester-based urethane resin and a vinyl chloride copolymer resin, and blended with various additives to form a solvent dispersion.
It is carried out by printing on a film with a gravure coater, drying, adsorbing and impregnating.
In addition, the thickness of the film, the thickness of the adhesive layer, and the like can be appropriately changed depending on the blending amount of the ultraviolet blocking agent in the present invention, and are not limited. About 500 micrometers is preferable and especially about 5-20 micrometers is used suitably.

  The “layer containing an ultraviolet blocking agent” in the present invention refers to a layer containing an ultraviolet blocking agent in a layered portion of an emergency bandage other than the support, specifically, an ultraviolet blocking agent-containing laminate on the support. Layer, UV-blocking agent-containing adhesive layer, part of the UV-blocking agent-containing laminate layer, adhesive layer adhesive surface and pad part, net, or between pads, between pad and cushioning material It represents an ultraviolet blocking agent-containing or coated film.

Any of the “layer containing an ultraviolet blocking agent” of the present invention can be blended with a colorant, a pigment, and a dye, and can be subjected to skin color processing generally used in the field of the emergency bandage. Further, it is possible to appropriately finish various colors so as to be slightly inconspicuous. Specific examples of such colorants, pigments, and dyes include titanium oxide pigments, insoluble azo yellow pigments, and insoluble azo red pigments, with titanium oxide pigments being particularly preferred.
In addition, the “layer containing an ultraviolet blocking agent” of the present invention can be made porous in order to further improve the air permeability and moisture permeability, but in particular, an ultraviolet blocking agent is kneaded. Alternatively, if the coated film is made of a perforated film, the effect of improving the air permeability is high, and the film can be perforated with an appropriate size and number in consideration of the location of the film. For example, when a film kneaded or coated with an ultraviolet blocking agent is used as the layer containing the ultraviolet blocking agent and the film is disposed below the pad portion, 1 hole having a hole diameter of about 50 to 70 μm is formed. It is preferable to drill about -15 pieces / square centimeter.
In addition, when a film kneaded or coated with a UV blocking agent that has been subjected to perforation treatment is disposed between the adhesive layer of the adhesive layer below the lower layer pad, the air permeability of the film that has been subjected to perforation treatment In order to ensure this, it is preferable to dispose a “diffusion material” between the film kneaded or coated with the perforated ultraviolet blocking agent and the adhesive surface of the adhesive layer.
“Diffusion material” is a material for preventing the UV cut film from being bonded to the adhesive surface of the adhesive layer and blocking the air holes formed in the UV cut film, and can provide a certain gap. The material is not particularly limited, and may be woven fabric, non-woven fabric, knitted fabric, or non-adherent paper, but preferably the same non-woven fabric as the pad is used.

  In addition, the “film for suppressing the penetration of the ointment” may be a film that effectively inhibits the ointment from penetrating into the lower layer of the pad portion over time due to the capillary phenomenon in the pad, and is a plastic such as a polyolefin film or a polyester film. Various materials such as film can be used. Depending on the degree of penetration, a fine perforation treatment may be sufficient to achieve the object of the present invention.

A specific embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 to 3, the support 1 serving as a base of an emergency bandage has appropriate flexibility, moisture permeability, breathability, and light transmittance. It is a rectangular sheet piece having a certain width and a certain length made of a synthetic resin sheet such as a thin polyolefin film having an adhesive, and an adhesive body is layered on the entire upper surface thereof. It is formed by applying a pressure-sensitive adhesive body on the upper surface of the support 1 by a calender roll method or the like, and constitutes a pressure-sensitive adhesive sheet (the support 1 and the pressure-sensitive adhesive layer 2 on one side of the support 1).
A pad portion 4 is fixed to the center of the upper surface of the adhesive surface 3 of the adhesive layer 2, and the pad portion 4 is usually impregnated or adsorbed with a drug 7. In the drawings of FIGS. 1 to 13, an ointment 7 a as a drug 7 is layered on the pad upper surface of the pad portion 4. The feature of the present invention is that a layer containing an ultraviolet blocking agent is supported. It is in the point arrange | positioned in parts other than 1, and is not limited to the emergency adhesive bandage which layered the ointment 7a. Therefore, in this feature, it is a technique (see, for example, FIG. 14) that is usually applied to a general emergency bandage and an emergency bandage on which a capsule containing a drug solution is placed. An adhesive bandage is a preferred embodiment, and the drawing shows an emergency bandage with an ointment. This technique can also be applied to ordinary emergency bandages using gauze (see, for example, FIG. 14).

  In FIG. 1, an ointment protective cover 8 is further superimposed on the adhesive surface 3 of the adhesive layer 2, and the lower surface of the ointment protective cover 8 is detachably attached to the adhesive surface 3 of the adhesive layer 2. Yes. This ointment protective cover 8 is made of a transparent synthetic resin thin-walled sheet such as a vinyl chloride resin that is non-breathable and has an appropriate rigidity, and has the same width as the support 1 made of the pressure-sensitive adhesive sheet and has a pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer. It is formed in a rectangular shape shorter in length. Further, a constant width and a constant length portion of the central portion of the ointment protective cover 8 in the length direction are bulged upward and formed into a gentle arc shape to form a blister portion 81 whose lower end is fully opened. Forming.

  Release films 91 and 92 are detachably attached to the adhesive surfaces 3 of the adhesive layer 2 at both ends of the support 1 projecting from both ends of the ointment protective cover 8. The inner end portions of the ointment protective cover 8 extend to the lower surfaces of both end portions, and the extended portions are folded upward to form overlapping end portions 91a and 92a, and the ointment protective cover is placed on the overlapping end portions 91a and 92a. Both ends of 8 are placed.

The pad 41 of the pad part 4 is characterized in that the layer containing the ultraviolet blocking agent is disposed in a portion other than the support 1 as described above, and contains the ultraviolet blocking agent of the present invention. In the technique for arranging the layers to be applied, the number of pads is not limited and can be applied to an emergency bandage for a single layer pad. However, in the case of an emergency bandage with an ointment, two or more pads 41a, 41b, .., Preferably laminated in the same quality, in order to suppress the penetration of the components of the ointment 7 below the pad portion 4 due to the capillary action of the ointment 7a.
In FIG. 2, the pad 4 is formed by laminating pads 41 (upper layer pads 41 a and lower layer pads 41 b), and the film 5 kneaded or coated with an ultraviolet blocking agent is the lower surface of the lowermost pad 41 b of the pad unit 4. And the entire side surface of the film 5 kneaded or coated with the ointment 7a layer pad 41a, the lower layer pad 41b, and the ultraviolet blocking agent. The entire pad portion 4 is fixed by coating and heat-welding the side surface of the net 6, and the pad portion 4 covered with the net 6 having a film 5 kneaded or coated with an ultraviolet blocking agent sandwiched between the layers. Is attached to the adhesive surface 3 of the adhesive layer 2.

The film 5 kneaded with or coated with an ultraviolet blocking agent is made of a thermoplastic film such as polyester as described above, and has a thickness of about 10 to 20 μm. Similarly, various additives can be blended or appropriate processing can be performed. Therefore, if necessary, a perforated film may be used to give the desired air permeability, or the desired light transmittance and moisture permeability may be obtained by appropriately selecting the type and amount of the compounding agent, or the skin color. Processing and slight coloring can also be applied.
It should be noted that a UV cut film obtained by applying UV cut processing to a synthetic resin film such as polyester film with an inorganic material UV scattering agent (zinc oxide, titanium oxide) and UV light applied to the synthetic resin film such as polyester film. 5b of UV cut processed film impregnated and adsorbed with absorbent, blended with synthetic resin film such as polyester film, inorganic material UV scattering agent (zinc oxide, titanium oxide) and UV absorber Then, the UV cut film subjected to the UV cut process is designated as 5c.

The pad portion 4 is composed of at least a pad 41 and a medicine 7 impregnated in the pad 41 (particularly an ointment 7a layered on the pad). Is preferably composed of an ointment 7a layered on the uppermost pad 41a, and if necessary, a film 10 for suppressing ointment permeation and a net 6 that surrounds and surrounds the pad 41 and is fixed by thermal fixation. The lower surface of the pad portion 4 is stuck on the adhesive surface 3 of the adhesive layer 2.
Two or more pads 41a, 41b,... Are made of gauze, absorbent cotton, other woven fabrics, non-woven fabrics, soft plastic fibers, or a laminate of these, and have a rectangular shape with a width. Is formed smaller than the width of the support 1 and shorter.
Each pad 41a, 41b,... Uses a different material and can give strength to suppression of permeation of the components of the ointment 7a. However, even if fibers of the same material are used, 2 pads are used. It has been found that by providing more than one sheet and providing an interface between the pads, the penetration of the ointment 7a fluid component due to capillary action is suppressed, but it is rather cheaper to use the same material while maintaining high quality Therefore, it is advantageous in industrial production.
Further, in FIGS. 2 to 3, the net 6 is covered over the lower surface both sides (FIG. 2) of the upper layer pad 41 a and the lower layer pad 41 b (FIG. 2) or the lower surface both sides (FIG. 3) of the pad 41. Is integrally fixed to both side surfaces of the pad portion 4 by thermal welding, and a predetermined amount of the ointment 7a is applied to the upper surface of the pad portion 4 from the net 6 through the mesh (not shown) of the net 6. Thinly layered. Accordingly, the ointment 7a is held in the mesh of the net 6, and there is no possibility of flowing on the pad 41 in the plane direction.

  The ointment protective cover 8 having the blister part 81 can be formed in various shapes. However, as described in Japanese Patent Application Laid-Open No. 2001-104367, the ointment protective cover 8 has a planar rectangular shape, and the central part is gently upward. A blister portion 81 having a dome-shaped cross section is formed by bulging and forming a circular arc shape, and both side wall portions on the long side of the blister portion 81 are inclined so as to approach each other upward from the lower end. The pad part which forms the wall part and the ointment is mounted on the upper surface is formed on the adhesive surface of the rectangular adhesive layer, and the four-sided peripheral wall part is higher than the thickness of the pad part 4 on which the ointment is layered. It is preferable to form such that the pad portion 4 is covered with the blister portion 81 by being detachably attached. When the ointment protective cover 8, the blister part 81, the standing wall part 82, and the pad part 4 are the same in covering form, the description of the aspect is the same as that described in JP-A-2001-104367. It is quoted as is in the description.

  That is, in FIG. 1, the shape of a typical ointment protective cover 8 is shown, and the blister portion 81 covers the pad portion 4 attached to the center of the upper surface of the rectangular adhesive sheet 2 and The adhesive surface of the adhesive layer 2 except for the lower surface of both ends of the ointment protective cover 8 in the length direction of the ointment protective cover 8 including the lower surface of the outer peripheral portion of the open end of the blister unit 81 in the state of being housed in the blister unit 81. 3 is attached to be peelable.

The blister part 81 is designed to be slightly larger than the pad part 4 at the four sides of the opening end of the blister part 81, and the pad part 4 is formed in the opening part so as to be housed.
Further, on the long side at the lower end of the opening of the blister portion 81, both sides thereof are formed as standing wall portions 82 having a crescent-shaped cross section inclined in a direction approaching each other upward from the long edge side of the opening end.
Further, the height of the ceiling wall portion 84 of the blister portion 81 is formed slightly larger than the thickness of the pad portion 4 on which the ointment 7a is layered, and is therefore accommodated in the open end of the blister portion 81. There is a gap between the adhesive layer 2 on the pad portion 4 and the lower surface of the ceiling wall portion 84 of the blister portion 81 so that the adhesive layer 2 does not adhere to the lower surface of the ceiling wall portion 84 of the blister portion 81. It is configured.

The emergency bandage of the present invention configured as described above is 95% even when irradiated with ultraviolet rays from the lower surface of the support 1 (the surface not having the adhesive layer) when attached to the lower surface of the pad portion 4, that is, the skin surface. As described above, preferably, not only can 98% to 100% be blocked and ultraviolet transmission can be effectively suppressed, but also the penetration of the ointment 7a component into the lower layer pad 41b is effectively suppressed and the wound mouth is prevented. Since it presses softly with moderate pressure, it has the advantage that it can be treated without damaging the wound.
The ultraviolet transmittance can be measured by a test method using a visible / ultraviolet spectrophotometer, an ultraviolet lamp, an ultraviolet sensor, and an ultraviolet radiometer.

  Next, in use, first, the ointment protective cover 8 is peeled from the adhesive layer adhesive surface 3 on the support. At this time, both ends of the ointment protective cover 8 are not adhered to the adhesive surface 3 of the adhesive layer 2, and release films 91 and 92 are interposed between the both ends and both ends of the adhesive sheet 2. Therefore, the end of the support 1 is picked with the fingertips of one hand, the ends of the ointment protection cover 8 are picked with the fingertips of the other hand, and these ends are separated, so that the ointment protection cover 8 can be removed with one touch. It can peel from the adhesion layer adhesion surface 3 of the support body 1, and the pad part coat | covered with the blister part 81 can be exposed. Next, the release films 91 and 92 are removed from both end portions of the support 1, and then the ointment 7 a layered on the pad portion 4 is applied to the wound mouth to adhere the adhesive layer on the support 1. Adhere surface 3 to the skin surface.

In FIG. 4, from the lower side of the pad portion 4, a thickness of 12 μm obtained by performing UV cut processing on one surface of the polyester film with an ultraviolet ray scattering agent (zinc oxide, titanium oxide, and / or a processed product thereof) made of an inorganic material. The UV-cut polyester film 5a, the woven fabric 60g / square meter pad 41b, and the woven fabric 80g / square meter pad 41a are laminated in sequence, leaving these 3 layers on both sides and the adhesive layer on the lower adhesive layer. It is covered with a net 6 made of a plastic such as polyethylene, and is fixed to the both sides by heat welding. The ointment 7a is passed through the net 6 through a mesh (not shown). By applying on the upper surface of the pad portion 4, the ointment 7a can be thinly layered.

  FIG. 5 is identical to the UV-cut polyester film 5a in FIG. 4 except that a UV-cut polyester film 5b having a thickness of 16 μm that is UV-cut by adding or coating an ultraviolet absorber is used. It is an enlarged view of a pad part. With this configuration, it is possible to obtain an emergency bandage that exhibits substantially the same ultraviolet transmittance as when an ultraviolet scattering agent is added even when an ultraviolet absorber is added.
