[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The embodiment of the present application solves the problem that the wound recovery condition cannot be directly observed through the band-aid by providing an ultra-thin band-aid, thereby realizing the widespread use of the band-aid.

[0028] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0029] The design mainly considers that the existing band-aid cannot directly observe the wound recovery, and how to directly observe the wound through the outer layer of the band-aid when the band-aid is attached to the wound. Based on the above considerations, the inventor found through research that by adjusting the material and thickness of the band-aid, it is easier to directly observe the wound through the band-aid while improving the function of the band-aid.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Example:

[0032] like Figure 1-Figure 3 As shown, an ultra-thin wound patch, the thickness of which is 100 microns to 130 microns, comprises a patch 3, and the patch 3 comprises a base material layer and a glue coating layer;

[0033] The substrate layer is an ultra-thin transparent PU film, and the adhesive layer is evenly coated on the substrate layer;

[0034] The coating layer is an acrylic adhesive mixed with a hydrophilic polymer material.

[0035] The adhesive layer can absorb exudate and has lasting stickiness. The patch 3 is configured as a combination of a base layer and an adhesive layer. The base layer adopts an ultra-thin transparent PU film, and the adhesive layer adopts an acrylic adhesive mixed with a hydrophilic polymer material. The thickness of the band-aid is set to 100 microns to 130 microns. This solves the problem in the prior art that the wound recovery cannot be directly observed through the patch 3 in the band-aid, and the band-aid needs to be removed when checking the wound, which makes the wound difficult to heal, increases the patient's pain, and increases the probability of bacterial infection.

[0036] The wound dressing also includes a release film layer 1 and a protective layer 2 for protecting the patch 3. The wound dressing is divided into a four-layer structure, which is a substrate layer, a glue layer, a release film layer 1 and a protective layer 2 in sequence. The release film layer 1 is divided into two pages, which are a placement page 11 and a cover hinge 12. A plurality of patches 3 are provided, and the plurality of patches 3 are pasted on the placement page 11. The glue layer is located between the placement page 11 and the substrate layer. The placement page 11 is used to carry the substrate layer and the glue layer, and the cover hinge 12 is a blank page.

[0037] A perforated dotted line is provided between the placement page 11 and the cover hinge 12 of the release film layer 1 to facilitate folding of the two pages, thereby achieving protection of the substrate layer and the adhesive layer on the placement page 11 by the cover hinge 12 .

[0038] The release film layer 1 is adjacent to the adhesive layer. After die-cutting, release films 31 of different shapes and die-cutting notches 32 corresponding to the release films 31 are formed on the release film layer 1 .

[0039] The peeling piece 31 and the die-cutting notch 32 are formed by die-cutting, so that the patch 3 can be peeled off through the peeling piece 31 , which is convenient for using the patch 3 .

[0040] The release film layer 1 and the protective layer 2 are both made of PET. The protective layer 2 is the same size as the release film layer 1, and the release film layer 1 is thicker than the protective layer 2. Figure 3 shown.

[0041] By providing the protective layer 2 , the peeling sheet 31 on the release film layer 1 can be torn off in one direction, preventing the user from peeling off the product in the wrong direction, while protecting the peeling sheet 31 on the release film layer 1 from being broken by external forces.

[0042] The plurality of patches 3 are arranged in different shapes.

[0043] When in use, the three layers of the base material layer, the adhesive layer and the release film layer 1 are first cut according to the different designs and layouts of the patch 3 to form a peeling piece 31 and a die-cutting notch 32. The peeling piece part formed does not overlap with the patch 3. After die-cutting, the protective layer 2 is installed on the side of the release film layer 1 away from the patch 3, and then holes are punched along the symmetry axis of the release film layer 1 to form a punching dotted line to facilitate the protection of the patch 3 by the cover hinge 12. When using the patch 3, the patch 3 is peeled off from the small part of the die-cutting notch 32 on the release film layer 1 through a small part of the peeling piece 31 for use, and most of the peeling piece 31 does not detach from the release film layer 1, so that the patch 3 can be used directly.

[0044] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0045] 1. By setting the patch 3 as a combination of a base layer and a coating layer, the base layer adopts an ultra-thin transparent PU film, the coating layer adopts an acrylic adhesive mixed with a hydrophilic polymer material, and the thickness of the band-aid is set to 100 microns to 130 microns, the problem in the prior art that the wound recovery cannot be directly observed through the patch 3 in the band-aid, and the band-aid needs to be removed when checking the wound, which makes the wound difficult to heal, increases the patient's pain, and increases the probability of bacterial infection.

[0046] 2. The peeling sheet 31 and the die-cutting notch 32 are formed by die-cutting, so that the patch 3 can be peeled off through the peeling sheet 31 and the patch 3 can be used more easily.

[0047] 3. By providing the protective layer 2, the peeling sheet 31 on the release film layer 1 can be torn off in one direction, preventing the user from peeling off the product in the wrong direction, and at the same time protecting the peeling sheet 31 on the release film layer 1 from being broken by external forces.
