Description

Technical Field

[0001] The utility model relates to a cooling and refreshing hydrogel patch. Background Art

[0002] Currently, most of the cooling patches on the market are made of hydrogel. After tearing off the anti-stick film, the user sticks the hydrogel cooling patch on the feverish area to achieve a cooling effect by evaporating the hydrogel. However, the cooling effect of the hydrogel patches on the market at this stage is relatively low. Once the patient's fever is high, the hydrogel patch will hardly bring a cooling effect.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a cooling and refreshing hydrogel patch, which contains mint ingredients and can enhance the cooling effect.

[0005] The utility model provides a refreshing and cooling hydrogel patch, which comprises a first hydrogel layer laid on a backing layer, a second hydrogel layer laid on the first hydrogel layer, and an anti-adhesive film covering the outer surface of the second hydrogel layer, wherein the first hydrogel layer is provided with a liquid seepage concave area on a connection surface close to the second hydrogel layer, a plurality of mint liquid capsules are arranged in the liquid seepage concave area on the first hydrogel layer, a plurality of liquid outlet micropores are distributed on the first hydrogel layer, and the liquid outlet micropores and the mint liquid capsules are staggeredly distributed.

[0006] In one or more embodiments, the first hydrogel layer is provided with a pit for storing the mint liquid capsule, the opening of the pit is connected to the liquid permeation concave area, and the opening of the pit is wide inside and narrow outside.

[0007] In one or more embodiments, the mint liquid capsule includes a film and mint liquid filled in the film.

[0008] In one or more embodiments, the diameter of the liquid outlet micropore gradually shrinks from the input port to the output port, and the output port diameter of the liquid outlet micropore is 0.1-0.5 mm.

[0009] In one or more embodiments, a hand portion is provided on the edge of the anti-sticking film, and the anti-sticking film is made of polyethylene material.

[0010] In one or more embodiments, the backing layer is made of non-woven fabric.

[0011] The beneficial effects of the utility model are as follows: the hydrogel patch contains mint liquid capsules. After the user sticks the hydrogel patch to the heated part, the mint liquid capsules can be broken by pressing the hydrogel patch. The mint liquid capsules seep out along the liquid outlet micropores on the second hydrogel layer and come into contact with the skin, thereby enhancing the cooling effect and having a refreshing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic diagram of the structure of the hydrogel patch according to an embodiment of the utility model. DETAILED DESCRIPTION

[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0014] Please see attached Figure 1 The utility model provides a refreshing hydrogel patch, which includes a first hydrogel layer 2 laid on a backing layer 1, a second hydrogel layer 3 laid on the first hydrogel layer, and an anti-adhesive film 4 covering the outer surface of the second hydrogel layer 3. The backing layer is made of non-woven fabric material, and the anti-adhesive layer is made of polyethylene material. The first hydrogel layer 2 is provided with a liquid seepage concave area 5 on the connecting surface close to the second hydrogel layer 3, and the first hydrogel layer 2 is provided with a plurality of mint liquid capsules 6 in the liquid seepage concave area 5. The first hydrogel layer 2 is provided with a plurality of liquid outlet micropores 7, and the liquid outlet micropores 7 are staggered with the mint liquid capsules 6. After the user sticks the hydrogel patch to the heated part, the mint liquid capsules are crushed by pressing the hydrogel patch, and the mint liquid in the mint liquid capsules first flows out to the liquid seepage concave area and gathers, and then slowly seeps out through the liquid outlet micropores and contacts the skin.

[0015] The first hydrogel layer 2 is provided with a concave pit for storing a mint liquid capsule 6, the opening of the concave pit is connected to the liquid seepage concave area 5, and the opening of the concave pit is wide inside and narrow outside. When the mint liquid capsule is crushed, the opening of the concave pit is wide inside and narrow outside, so that the mint liquid can be prevented from seeping out all at once, and the liquid seepage concave area also plays a buffering role. Specifically, the mint liquid capsule 6 includes a film and a mint liquid filled in the film.

[0016] The caliber of the liquid outlet micropore 7 gradually shrinks from the input port to the output port, and the output port caliber of the liquid outlet micropore 7 is 0.1-0.5 mm, preferably 0.1 mm, 0.2 mm, 0.25 mm, 0.3 mm and 0.35 mm. The different calibers are determined according to the size of the cooling patch. The caliber for adults can be larger, and the small-sized hydrogel patch for infants can use a smaller caliber.

[0017] In order to facilitate the user to tear off the anti-adhesive film, a grip portion 41 is provided on the edge of the anti-adhesive film 4 .

[0018] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
