Description

考 This invention relates to a wound protection bandage which covers and protects a wound surface of a body with a pad to which a disinfectant is applied.

In general, wound adhesive plasters are prepared by attaching dried gauze to an adhesive tape, covering the adhesive surface and the pad with release paper, and packing them in a paper bag or the like. However, in this wound bandage, the gauze in the pad portion was only impregnated with a dry disinfectant and disinfectant, the disinfectant was small, and the disinfecting effect for deep wounds and dirty wounds was weak.

Therefore, as disclosed in, for example, Japanese Utility Model Application Laid-Open No. Sho 62-42818 and Japanese Utility Model Application Laid-Open No. 9-251, there has been proposed a bandage that is used by impregnating a gauze of a pad portion with a chemical solution when used.

However, in the case of the structure disclosed in Japanese Utility Model Application Laid-Open No. 62-42818, it is difficult to use a sterilizing and disinfecting chemical solution by dripping it from the outside of the bandage. There were drawbacks. On the other hand, in the device disclosed in Japanese Utility Model Laid-Open No. 9-251, a pad portion is superimposed on a blister pack containing a chemical solution, and in use, the blister pack is pushed to break the chemical solution into the pad portion. It is applied to the wound, and can be used in the same manner as a normal wound plaster except that the blister pack is crushed when used. However, there is a problem in that the number of manufacturing processes and materials is increased, and the product cost is increased, for example, a chemical solution is put in a blister pack, sealed and packaged, and a bandage portion is integrally attached. Further, there is another problem that the operation of pushing the blister pack through during use is troublesome.

The present invention has been made in view of the above-mentioned conventional problems, and is intended to provide a wound protecting bandage which is easy to manufacture, inexpensive, easy to use, and has a long-lasting and effective sterilizing effect. Aim.

According to the invention, an adhesive film having an adhesive layer on its surface is provided, a pad portion having a size enough to be surrounded by the adhesive layer, and the pad portion is impregnated with a liquid disinfectant / disinfectant. And a wound protection bandage in which the pad portion and the surrounding pressure-sensitive adhesive layer are covered with a release film.

表面 The surface of the pad portion is covered with a coating material through which the liquid germicide can pass. A resin film having good adhesion to the pressure-sensitive adhesive layer is integrally provided on the pad portion, and the resin film is attached to the pressure-sensitive adhesive layer. The pressure-sensitive adhesive film is a film in which a nylon net is provided on the pressure-sensitive adhesive layer side of a urethane film coated with a pressure-sensitive adhesive. The release film around the pad portion is a heavy release film, and the heavy release film is adhered to the pressure-sensitive adhesive layer by pressing.

According to the wound protection bandage of the present invention, the liquid medicine can be stored for a long period of time, and can be easily used by peeling off the release paper as in the case of the conventional wound bandage. Then, since the liquid disinfectant is in contact with the wound surface of the skin, the healing of the cells at the wound site can be promoted and the natural healing can be sped up as compared with the case where the bandage of the dry pad portion is applied. The availability of liquid drugs increases the variety of drugs that can be used, allowing for more effective disinfection and other benefits. The disinfectant disinfects the drug without damaging the wound surface, uniformly acts on the wound site, and reliably prevents bacteria from entering. Furthermore, it does not adhere to the wound site, heals quickly, and there is no pain when changing the wound protective bandage.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 and 2 show an embodiment of the present invention. A wound protection bandage 10 of this embodiment has a support film 12 such as a thin rectangular PET. The support film 12 is preferably made of a material that does not adsorb a liquid drug. One surface of the support film 12 is provided with a nylon net 14 of the same shape and a pressure-sensitive adhesive layer 16 to constitute a pressure-sensitive adhesive film 18. A pad portion 20 is provided at the center of the surface on which the adhesive layer 16 is formed. Release films 22 and 23 are attached and covered on the adhesive layer 16 and the pad portion 20.

The pad portion 20 is preferably a nonwoven fabric or woven fabric having a basis weight of 150 to 200 g / m ² and a thickness of 0.5 to 1 mm. Further, the pad portion 20 is covered at least on the surface side with a covering material 26 such as a thin perforated film or a net, and covered with the covering material 26 so that the liquid disinfecting and disinfecting agent can pass therethrough.

The release film 22 is a release material made of a soft polyolefin film of 20 to 30 μm. The release film 22 may be a heavy release film that has not been subjected to a surface treatment for losing the adhesiveness with the adhesive layer 16. This makes it difficult for the liquid disinfectant to leak from the pad section 20. Here, heavy peeling refers to the degree of force when a tape having a width of about 25 mm is adhered and peeled off, and when expressed numerically, is 5.0 to 10.0 N / 25 mm, preferably 7.0 to 8.5 N. / 25 mm. Also, light peeling for heavy peeling refers to the degree of force when a tape having a width of about 25 mm is adhered and peeled off, and when expressed numerically, refers to a tape that can be peeled off with a force of 0.5 N / 25 mm or less, It preferably refers to one set to a peeling force of about 0.2 to 0.3 N / 25 mm.

In the pad section 18, as a liquid disinfectant, acrylol, chlorhexidine gluconate, benzalkonium chloride, isopropanol, benzethonium chloride, oxidol, ethyl alcohol, naphazoline hydrochloride, chlorpheniramine maleate, popyon iodine, cetylpyridinium chloride, etc. Is impregnated as a liquid. Further, agents such as lidocaine and dibucaine hydrochloride as a local anesthetic, and allantoin as a skin repair agent may be blended. Further, an antibiotic may be blended. Furthermore, in order to make the affected part wet, physiological saline may be impregnated.

Next, a method for manufacturing the wound protective bandage 10 of this embodiment will be described. First, the covering material 26 is attached to the surface of a material such as a nonwoven fabric forming the pad portion 20. The material such as a nonwoven fabric forming the pad portion 20 is a long material formed in the width of the pad portion 20 in the longitudinal direction, and is a continuous and elongated material wider than the pad portion 20 so as to wrap the pad material. Continuously cover with coating material.

The pad portion 20 is formed on the adhesive film 18 so as to have a width such that the adhesive layer 16 is exposed therearound. The pad portion 20 is impregnated with a liquid disinfectant and disinfectant. Cut to a size that can be stuck to.

Next, the pad section 20 is attached to the adhesive layer 16 of the adhesive film 18. Then, a release film 23 is attached from the adhesive layer 16 at one end of the adhesive film 18 to the pad portion 20. Next, from the other side, the pad 20, a part of the release film 23, and the remaining part of the adhesive film 18 are covered with the release film 22 of the same shape. Further, the release films 22 and 23 around the pad portion 20 are pressed against the pressure-sensitive adhesive layer 16 to reinforce the adhesion so that the liquid disinfectant does not leak to the periphery.

According to the wound protection bandage of this embodiment, the pad portion 20 is covered with the release films 22 and 23, and the release films 22 and 23 are adhered to the surrounding adhesive layer 16 because the liquid disinfectant is impregnated. The pad portion 20 is securely covered, and the chemical solution is not easily evaporated. The packaging is hermetically sealed with an aluminum laminate film, so that evaporation of the chemical solution can be suppressed even during long-term storage. Note that as the sealant material inside the laminate film, a material such as Saralin or EMAA to which a chemical solution is not adsorbed may be used.

使用 In the wound protection bandage of this invention, at the time of use, the liquid disinfectant disinfectant comes into contact with the wound surface of the skin, a reliable disinfecting effect is obtained, and continuous use for a long time is possible. In addition, by sterilizing the wound and covering it in a moist and sealed state, a treatment promoting effect can be obtained, and labor saving of nursing becomes possible. In addition, by providing the covering material 26 at the portion in contact with the wound, the nonwoven fabric or the like does not adhere to the wound.

The wound protection bandage of the present invention is not limited to the above embodiments. As shown in FIG. 3, a resin film 24 such as a soft polyolefin or polyethylene is heat-welded to one surface of the pad portion 20. Alternatively, it may be formed so as to be adhered and securely adhered to the adhesive layer 16.
