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.
