Description

  The present invention relates to a wound dressing for protecting the surface of a wound site of a body and a method for manufacturing the same.

  Wound dressings are generally used to treat or protect wounds such as burns, abrasions, cuts, and pressure sores (floor scrub), but also to protect sutures after surgery or orthopedic surgery. Many are used.

  The color of the surface of the wound dressing is generally white (Patent Document 1), but the skin color is used to relieve the color discomfort between the surface of the wound dressing and the surrounding skin. There are many cases.

JP 2008-099773 A

  The skin surface of the body presents a complex pattern due to many fine wrinkles, body hairs and blood vessels, etc., and such skin surface patterns differ in gender and age differences, and also differ in individuals, The color of the skin is also very different. Therefore, as described above, even if the surface color of the wound dressing is set to a uniform skin color, it is difficult to avoid the application of the wound dressing from the surroundings. In particular, when it is used to cover a sutured part or the like after facial orthopedic surgery, even if there is a little discomfort, it is very worrisome for the patient.

  The purpose of the present invention is to reduce the difference in the pattern and color of the wound dressing application site and the surrounding skin surface, and to cover the wound site so that the application site of the wound dressing does not stand out. It is to provide a covering material. It is also an object to provide a production method capable of producing such a wound dressing.

  In order to solve the above-mentioned problems, the wound dressing according to the present invention has a non-wound skin color image of a wound site to be coated on one side of a thermoplastic resin film, or a skin color image of a site other than the wound site. Is printed, and has an adhesive on the other side of the thermoplastic resin film.

  In the wound dressing, preferably, a region surrounding a printing region where the skin color image is printed is a transparent region not including the printing ink layer. Moreover, the skin color ink layer which has light-shielding property is formed in the said other surface side of the said thermoplastic resin film. This flesh-colored ink layer can also be formed between one side of the thermoplastic resin film and the printing ink layer.

  The method for producing a wound dressing according to the present invention includes a reading step of reading a non-wound skin color image of a wound site to be coated or a skin color image of an area other than the wound site, And printing the skin color image on one side of the thermoplastic resin film based on the shape and color data.

  According to the wound dressing according to the present invention, the discomfort regarding the skin pattern and the color can be greatly reduced between the wound dressing and the surrounding skin surface, and the place where the wound dressing is applied is not noticeable and is noticed. It becomes difficult to be.

  In particular, if a transparent area is provided around the print area, the skin surface that is transparent in the transparent area becomes an intermediate view between the skin color image in the print area and the actual skin surface. From the color image of the skin surface to the actual skin surface through the skin surface that can be seen through in the transparent region, it is gradually changed step by step. Thereby, like a gradation, it looks uncomfortable, the boundary between the wound dressing and the actual skin surface is not conspicuous, and it is even more difficult to notice that the wound dressing is being applied.

  Furthermore, when a skin-colored ink layer having a light-shielding property is formed on the other surface of the printing region, it is possible to reliably prevent a wound site or an internal scratch pad covering the wound region from being seen through the surface of the covering material, In addition, since the flesh color ink layer is flesh colored, the hue of the flesh color image in the print area is not harmed.

  According to the manufacturing method according to the present invention, a wound dressing can be manufactured immediately by taking a picture of a patient's skin surface in a hospital or clinic, and for each patient, quickly and accurately, Wound dressings can be used.

  FIG. 1 shows a wound dressing 1 attached to the skin surface A2 of a body. A commercially available wound pad 10 is arranged so as to cover a wound area A1 of a wound site. It is affixed on the skin surface A2. And the wound dressing 1 is arranged so as to cover the wound pad 10 with a sufficient area, and the wound dressing 1 is applied to the wound pad 10 by the adhesive 2 applied to the skin surface A2 side. It is affixed on the skin surface outside the region and the surface of the wound pad 10. A large number of ventilation micropores 3 are formed in a portion outside the area of the wound pad 10 of the wound dressing 1. The adhesive 2 is applied in the form of dots or streaks so as not to block the fine holes 3.

  FIG. 2 is an enlarged cross-sectional view of an arrow II portion in FIG. 1, and the wound dressing 1 is mainly made of a transparent thermoplastic resin film 5 used for a stencil sheet of a stencil printing machine. This thermoplastic resin film 5 Is printed on the other surface side of the thermoplastic resin film 5 with a light-shielding property on the other side. The skin color ink layer 7 and the pressure-sensitive adhesive 2 are included. The skin color image printed on the printing ink layer 6 is a skin surface color image at the time of non-wounding of the wound site to be coated or a skin color image of a site other than the wound site. In particular, when a skin color image of a part other than the wound part is used, a skin color image of a part on the opposite side corresponding to the wound part is preferable in the same patient. This is because the skin pattern or shape of the part corresponding to the left and right of the same person is usually similar.

  As the thermoplastic resin film 5, for example, a stretched polyethylene terephthalate (PET resin) film or a polyolefin film is used. When a thermal head for stencil plate making of a stencil printing machine is used for drilling the fine holes 3, preferably a polyethylene terephthalate film having a thickness of 1.5 to 3 μm is used, and a polyolefin film is thick. Having a thickness of 3 to 10 μm is used. In addition to the polyethylene terephthalate film or polyolefin film, polyester resin, polyethylene resin, polyvinyl chloride resin, polyvinylidene chloride resin, polymethylpentene resin, polypropylene resin, polyethylene naphthalate resin, polyvinyl alcohol resin, nylon 6, etc. No film is available.

  FIG. 3 is an enlarged cross-sectional perspective view of the arrow III portion of FIG. 1, and the area surrounding the print area S1 where the print ink layer 6 on which the skin color image is printed and the skin color ink layer 7 exists is the print ink layer 6. In addition, since the skin color ink layer 7 is not formed, the skin surface A2 is seen through the transparent region S2. P1 indicated by a solid line indicates an actual wrinkle on the skin surface, P2 indicated by a solid line indicates a wrinkle printed on the print region S1, and P3 indicated by a broken line indicates a transparent thermoplastic resin film 5 in the transparent region S2. It shows a cocoon that can be seen through.

  The fine holes 3 are formed with a diameter of about several tens of μm to 50 μm. Further, each microhole 3 is formed by thermal perforation, and therefore, the peripheral edge 3a at both ends of the microhole 3 has a round shape due to shrinkage of a film melted by heat during processing.

  FIG. 4 shows an example of a manufacturing apparatus for the wound dressing material 1 in a medical site such as an examination room. The manufacturing apparatus includes a tablet terminal 21 or a digital camera having a camera function and a printer 22 having a color printing function. I have. The printer 22 may further include a thermal head for making a stencil printing machine for thermal drilling of fine holes.

(Manufacturing and usage)

The example shown in FIG. 4 shows a case where the patient has an injury site (affected part) X1 in the right hand RH, and a site X2 corresponding to the wound site X1 of the right hand RH is selected from the left hand LH of the patient. , Color shooting.

  The data of the photographed skin color image X2a is obtained by photographing the part X2 of the patient's left hand LH. Preferably, the data is reversed left and right in order to match the wound part X1 of the right hand RH. To enter. The printer 22 prints a left-right reversed image of the skin color image of the portion X2 at the same magnification on one side of the thermoplastic resin film 5 based on the left-right reversed data. In FIG. 1, the fine holes 3 may be formed in advance on the outer peripheral end of the thermoplastic resin film 5 before printing, but at the same time as printing, the thermal head is formed on the outer peripheral end of the thermoplastic resin film 5. May be heat drilled.

  After manufacturing the wound dressing 1, as shown in FIG. 1, first, the wound pad 10 is applied to the skin surface so as to cover the wound area A1 of the wound site, and further covered with the wound dressing 1 from above, The wound dressing 1 is attached to the skin surface outside the wound area A1 of the wound site with the adhesive 2.

(Effects of the first embodiment)
(1) Since the color image which image | photographed the skin surface of the patient who has a wound is printed on printing area | region S1, between the wound dressing 1 and the surrounding skin surface A2, a skin pattern and color The discomfort concerning can be greatly reduced, the place where the wound dressing 1 is pasted becomes inconspicuous, and it becomes difficult to notice that the wound dressing 1 is pasted.

(2) The transparent region S2 is formed so as to surround the outer periphery of the print region S1, and the skin surface seen through the transparent region S2 is intermediate between the skin color image in the print region S1 and the actual skin surface. Since it becomes visible, the color changes sequentially from the skin color image of the print region S1 to the actual skin surface through the skin surface seen through in the transparent region S2. Thereby, gradation is formed, the wound dressing material 1 and its surroundings can be seen without a sense of incongruity, the boundary between the wound dressing material 1 and the actual skin surface is not conspicuous, and the wound dressing material 1 is further pasted. It becomes difficult to notice.

(3) Since the skin-colored ink layer 7 having a light-shielding property is formed on the surface opposite to the printing ink layer 6 side of the thermoplastic resin film 5, the wound site or the internal wound pad 10 covering the wound site is a covering material It can be surely prevented from being seen through from the surface, and the flesh-colored ink layer 7 is flesh-colored, so that the hue of the flesh-color image in the printing region S1 is not harmed.

(4) As shown in FIG. 1, the micropores 3 are not formed in the region corresponding to the wound pad 10 covering the wound site, and the micropores 3 are formed only in the region outside the wound pad 10. Later, the wound site remains sealed. Therefore, the exudate L1 exuded from the affected area accumulates at the wound site, maintains the wound site in a moist state, and prevents drying. Thereby, not only the hygienic state of the wound site is maintained, but also the generation of scabs at the wound site is prevented, the generation of pain due to the scabs is suppressed, and the regeneration of the wound is promoted. On the other hand, the outer peripheral edge region adhered to the skin surface is kept in a dry state by the air permeability of the micropores 3 and can prevent stuffiness and the like.

(5) Since the microscopic holes 3 are formed by thermal perforation, both end opening edges 3a of the microscopic holes 3 have a round shape. Therefore, when the thermoplastic resin film 5 comes into contact with the skin, it is smooth. It becomes a touch and does not give the user a discomfort. In addition, the opening edge 3a rounded by heat shrinkage has high strength and is not easily broken from the opening edge 3a.
