[0032] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0033] like Figure 1 As shown, an embodiment of this utility model provides a band-aid, comprising:

[0034] Backing layer 1;

[0035] Hemostatic layer 2 is fixedly connected to the first side of the backing layer 1;

[0036] The first release layer 31 is bonded to the first side of the backing layer 1;

[0037] The backing layer 1 is provided with indentations 4 to facilitate tearing and cutting.

[0038] In this embodiment, as Figure 1 As shown, the first side of the backing layer 1 has adhesive material, and a first release layer 31 is adhered to the top of the backing layer 1. The first release layer 31 adheres to the backing layer 1 and does not cover the hemostatic layer 2, thus protecting the adhesive bandage before use and preventing it from sticking together. The edge of the first release layer 31 has raised portions that protrude from the edge of the backing layer 1, making it easy to tear and remove. The hemostatic layer 2 is located in the center of the adhesive side of the backing layer 1 and is loaded with chitosan / gelatin / collagen / alginate or other natural polymers that can achieve hemostasis. The preferred material of the hemostatic layer 2 is polyolefin. Spunlace nonwoven fabric is bonded to natural polymer hemostatic materials with adhesives. Alternatively, natural polymer materials can be directly prepared into hemostatic materials with a certain structure through spinning, cross-linking, or freeze-drying to achieve hemostasis, block microorganisms, and promote wound healing. The backing layer 1 has indentations 4 for easy tearing. The indentations 4 are designed and made during the printing of the backing layer 1. When using the bandage, it can be torn along the indentations 4 according to the application position. This is intended to solve the problem of not being able to pull according to the shape of the wound, especially for skin injuries such as joints, fingertips, and cracks that cannot be comfortably and effectively applied.

[0039] In an optional embodiment of this utility model, the backing layer 1 is folded along the crease 5 toward the second side to form a strip.

[0040] In this embodiment, as Figure 4 , Figure 5As shown, the backing layer 1 can be folded into a smaller shape along the crease 5 to the second side as needed, the crease 5 divides the backing layer 1 into a central part and a foldable part, such as folding the band-aid into a long strip shape which is often used by the general band-aid, so as to facilitate storage and carrying.

[0041] In an optional embodiment of the utility model, the band-aid further comprises: a second release layer 32 covering the folded part of the backing layer 1.

[0042] In the embodiment, as shown in Figure 1 、 Figure 3 、 Figure 5 As shown, after the backing layer 1 is folded to the second side, the second release layer 32 is used to paste and cover the folded part, so that the band-aid maintains the overall shape when not in use, and is easy to peel and unfold when in use.

[0043] In an optional embodiment of the utility model, the backing layer 1 is circular or elliptical.

[0044] In the embodiment, as shown in Figure 6 、 Figure 7 After the backing layer 1 is unfolded, it is circular or elliptical, and uniformly provided with indentations 4, so as to be easily torn into different shapes according to different use conditions.

[0045] In an optional embodiment of the utility model, the indentations 4 of the backing layer 1 are regularly distributed with eyelets.

[0046] In the embodiment, as shown in Figure 6 、 Figure 7 、 Figure 8 The indentations 4 are printed with regular breathable mesh holes, so as to be quickly and conveniently torn into different shapes when in use.

[0047] In an optional embodiment of the utility model, the backing layer 1 is made of non-woven fabric or polyurethane film.

[0048] In an optional embodiment of the utility model, the first side of the backing layer 1 is provided with an acrylic adhesive material, and the first release layer 31 is pasted and connected with the first side of the backing layer 1 through the acrylic adhesive material.

[0049] In the embodiment, acrylic is used as the adhesive material, which can not only have adhesion, but also not harm the skin.

[0050] In an optional embodiment of the utility model, the first release layer 31 comprises at least two pieces of release paper.

[0051] In the embodiment, as shown in Figure 2 、 Figure 9 、 Figure 10As shown in the first release layer 31 includes at least two pieces of release paper, so as to facilitate the use of convenient, fast tear release paper.

[0052] In an optional embodiment of the utility model, the second release layer 32 includes at least two pieces of release paper.

[0053] In the embodiment, as shown in the first release layer 32 includes at least two pieces of release paper, so as to facilitate the use of convenient, fast tear release paper. Figure 2 、 Figure 9 、 Figure 10 As shown in the first release layer 32 includes at least two pieces of release paper, so as to facilitate the use of convenient, fast tear release paper.

[0054] In an optional embodiment of the utility model, the hemostatic layer 2 is located at the center position of the first side of the backing layer 1.

[0055] In the embodiment, as shown in the first release layer 32 includes at least two pieces of release paper, so as to facilitate the use of convenient, fast tear release paper. Figure 6 、 Figure 7 As shown in the first release layer 32 includes at least two pieces of release paper, so as to facilitate the use of convenient, fast tear release paper.

[0056] Before use, according to the wound position to determine whether to need to unfold or partially unfold the adhesive plaster and can be along the indentation tear cutting, according to the wound position changes form, facilitate more flexible and stable to the wound place where need hemostasis or physical barrier and can be according to the shape of the wound to pull, especially suitable for joints, fingertips and cracking skin damage.

[0057] The above is the preferred embodiment of the utility model, it should be pointed out that, for the ordinary skilled person in the art, without departing from the principle of the utility model described, can also make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the utility model.
