Problems solved by technology

Some eye patches on the market do not have a fixing device, and are directly absorbed by wet hydrogel or wet film cloth by the tension of water. However, due to the low adhesion of this form of product, the user needs to lie on the supine position. The stickers are easy to fall off or fall off, and there are also other fixing methods such as using eye masks or headbands to fix them on the head, but this is more troublesome

Embodiment 1

[0027] like figure 1 and figure 2 As shown, the hydrogel eye protection patch of the present embodiment includes a hydrogel layer 1, a medical tape layer 2 and a non-woven layer 3 that is hydrophilic on one side and water-repellent on the other side, and the non-woven layer 3 It is arranged between the medical tape layer 2 and the hydrogel layer 1, and the hydrogel layer 1 is connected by a hydrophilic surface, and the adhesive surface of the medical tape layer 2 is connected by a water-repellent surface; the medical tape layer 2 is completely Covers the setting positions of the hydrogel layer 1 and the non-woven fabric layer 3, and is provided with an adhesive edge 21 beyond the setting positions of the two. In this arrangement, due to the existence of the medical tape layer 2, compared with a separate hydrogel or using an additional fixing device, it can not only play a good fixing role, but also avoid tedious operation steps. You can also walk around freely during the pr...

Embodiment 2

[0039] This embodiment is basically the same as Embodiment 1, and the difference is that, such as image 3 As shown, in this embodiment, a through hole penetrating through the hydrogel layer 1 , the non-woven fabric layer 3 and the medical tape layer 2 is provided in the middle of the hydrogel eye protection sticker. Although this setting method is connected with the environment and affects the moisturizing and hydrating effect of the product to a certain extent, it is more convenient for users to use their eyes and does not affect user activities.

Abstract

The invention discloses a hydrogel eye protection patch and a preparation method thereof.The hydrogel eye protection patch comprises a hydrogel layer and further comprises a medical adhesive tape layer and a non-woven fabric layer, one side of the non-woven fabric layer is hydrophilic, the other side of the non-woven fabric layer is water-repellent, the non-woven fabric layer is arranged between the medical adhesive tape layer and the hydrogel layer and is connected with the hydrogel layer in an attached mode through the hydrophilic surface, and the hydrogel layer is connected with the medical adhesive tape layer through the non-woven fabric layer. The adhesive surface of the medical adhesive tape layer is attached and connected through the water-repellent surface; the medical adhesive tape layer completely covers the setting positions of the hydrogel layer and the non-woven fabric layer and is provided with an adhesive edge exceeding the setting positions of the hydrogel layer and the non-woven fabric layer. The hydrogel eye protection patch has the advantages of being simple in structure, reasonable in arrangement, firm in adhesion and the like, the method for preparing the hydrogel eye protection patch also has the advantages, and the hydrogel eye protection patch further has the advantages of being simple in step, convenient to implement and the like.

Description

technical field [0001] The invention relates to the technical field of eye patch structures, in particular to a hydrogel eye protection patch and a preparation method thereof. Background technique [0002] Medical eye patch is mainly used outside the eyes of patients undergoing general anesthesia surgery or patients in deep coma. It provides patients with a relatively closed and humid environment to prevent exposure keratitis. It can also be used to protect eyes, relieve fatigue, and eliminate dark circles. At present, some eye patches on the market do not have a fixing device, and are directly adsorbed by wet hydrogel or wet film cloth by the tension of water. However, due to the small adhesion of this form of product, the user needs to lie on the back, and the eyes in other positions The stickers are easy to fall off or fall, and there are other fixing methods such as using eye masks or headbands to fix the head on the head, but this is more troublesome.
