Description

Technical Field

[0001] The utility model belongs to the technical field of cold compresses, and in particular relates to a cold compress composed of silicone gel and hydrogel. Background Art

[0002] The cold compress patch is a product developed and improved based on the traditional cold compress method. It lowers the local tissue temperature, causes local capillaries to contract, reduces local congestion, and relieves local swelling and pain. It can effectively relieve pain and swelling in the early stages of acute injuries such as sprains, strains, and bruises.

[0003] During use, existing cold compress patches will produce many wrinkles when they adhere to the body due to the different locations where cold compresses are required, resulting in poor conformity of the cold compress patches and thus poor cold compress effects. In addition, the adhesives of most existing cold compress patches are oil-based hot melt adhesives with active ingredients, which can easily cause allergic reactions after long-term application and are painful when removed. Utility Model Content

[0004] The technical problem to be solved by the present invention is that the existing cold compress patch has poor conformability during use, which results in poor cold compress effect. At the same time, the adhesive of the cold compress patch is mostly oily hot melt adhesive with active ingredients, which can easily cause allergic reactions after long-term application and is painful when removed.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is a cold compress patch composed of a silicone gel and a hydrogel, comprising a hydrogel base layer and a silicone gel base layer, wherein the hydrogel base layer is located in the middle position of one side of the silicone gel base layer, and the other side of the silicone gel base layer is adhered with a tensile layer and a flexible surface layer in sequence, and the outer side of the hydrogel base layer is adhered with a release film.

[0006] Preferably, the peel strength of the hydrogel base layer is 8 N / m, and the stickiness is 2S under the adhesion area of ​​30 mm*24 mm.

[0007] Preferably, the peel strength of the silicone gel base layer is 40 N / m, and the adhesiveness is 45S under the adhesion area of ​​30 mm*24 mm.

[0008] Preferably, the area of ​​the hydrogel base layer is smaller than that of the silicone gel base layer, and the areas of the waterproof layer and the flexible surface layer match the shape of the silicone gel base layer.

[0009] Preferably, the tensile layer is a TPU film.

[0010] Preferably, the flexible surface layer is stretch fabric.

[0011] Preferably, the release film matches the shape of the silicone gel base layer, the middle of the release film adheres to the hydrogel base layer, and the edge of the release film adheres to the silicone gel base layer. The release film is made of transparent material.

[0012] The advantages of this utility model compared with the prior art are:

[0013] This cold compress patch adopts a combination of silicone gel and hydrogel. The flexibility of silicone gel and hydrogel enables it to fit the body parts, making it more comfortable to use. At the same time, silicone gel and hydrogel themselves have strong air permeability, which can effectively ventilate and dissipate heat to the contact parts. The peel strength and adhesion of silicone gel are better than those of the hydrogel in the center part. It can not only be effectively applied to the user's skin, but also has low tear strength, which can effectively avoid allergic reactions, and there is almost no pain when peeling it off.

The areas of the waterproof layer and the flexible surface layer 4 match the shape of the silicone gel base layer 2. The tensile layer 3 is a TPU film, which fixes the shape of the silicone gel base layer 2 through the tensile layer 3. The flexible surface layer 4 is an elastic fabric, which can be deformed to a certain extent through the elastic fabric, and then deformed in accordance with the cold compress area of ​​the body. A release film 5 is adhered to the outside of the hydrogel base layer 1. The release film 5 matches the shape of the silicone gel base layer 2, and the middle of the release film 5 is adhered to the hydrogel base layer 1, and the edge of the release film 5 is adhered to the silicone gel base layer 2. The release film 5 is made of a transparent material. The release film 5 protects the hydrogel base layer 1 and the silicone gel base layer 2 and is easy to peel off and use.

[0023] In the present invention, the peel strength of the hydrogel base layer 1 is 8N / m, and the adhesion is maintained for 2S under the adhesion area of ​​30mm*24mm; the peel strength of the silicone gel base layer 2 is 40N / m, and the adhesion is maintained for 45S under the adhesion area of ​​30mm*24mm.
