[0023] Embodiment:

[0024] The embodiments of the present application disclose a patch having the function of retaining liquid medicine on the skin surface. Please refer to Figure 1 and Figure 2, including a protective layer 1, a dressing layer 2 is provided on one side of the protective layer 1, an adhesive layer 4 is provided on the side of the dressing layer 2 facing away from the protective layer 1, a release layer 5 is provided on the side of the adhesive layer 4 facing away from the dressing layer 2, and the protective layer 1 and the release layer 5 are respectively located on the outermost layers on the upper and lower sides of the dressing. A plurality of through holes 3 are formed in the inner cavity of the adhesive layer 4 in a penetrating manner, and a half hole 6 is correspondingly communicated with one side of each through hole 3, and each half hole 6 is formed on the side of the dressing layer 2 facing the adhesive layer 4. A connecting semi-circular piece 51 is fixedly connected to a corner on the side of the release layer 5 facing away from the adhesive layer 4, a traction wire body 52 is fixedly connected to one side of the connecting semi-circular piece 51, and a wax dripping point 53 is jointly provided on the outer surface of the release layer 5 at the end of the traction wire body 52 facing away from the connecting semi-circular piece 51. Among them, under the design of the connecting semi-circular piece 51, the traction wire body 52 and the wax dripping point 53 on one side of the release layer 5, while the wax dripping point 53 can be used to drip-wax and fix one end of the traction wire body 52, it can also be used in the process of using the overall dressing. By pulling the traction wire body 52, the release layer 5 can be lifted on the surface of the adhesive layer 4. However, before pulling the traction wire body 52, it is necessary to first break the adhesion and integrity of the wax dripping point 53 so that the traction wire body 52 can be separated from the close state on the outer surface of the release layer 5.

[0025] Please refer to Figure 1 , the plurality of through holes 3 and the half holes 6 are distributed in a matrix at the connection of the dressing layer 2 and the adhesive layer 4, and the hole diameters of each through hole 3 and the half hole 6 are in the range of 0.1 mm to 1 mm, and the distance between the holes is controlled in the range of 1 mm to 5 mm. The dressing layer 2 is made of polyurethane film or TPE film material, and the thickness of the dressing layer 2 is controlled in the range of 5 μm to 50 μm. Among them, under the material design of the dressing layer 2, it has good waterproof and antibacterial functions, and at the same time it has a certain water vapor permeability, so that the sweat of the skin at the pasting part can be discharged normally, preventing maceration or water vapor accumulation. The material of the adhesive layer 4 is one of hot melt pressure-sensitive adhesive, polyacrylate pressure-sensitive adhesive, polyurethane pressure-sensitive adhesive or silicone gel, and the weight per square meter of the adhesive layer 4 itself is between 10 g / ㎡ and 100 g / ㎡. Under the material limitation of the adhesive layer 4, it is mainly used to paste on the skin surface to play a fixing role. Moreover, under the design of the adhesive layer 4, the overall dressing itself has good self-adhesion, so it does not need to be used in combination with a secondary fixing dressing, and there is an extended effect of being more convenient and efficient to use;

[0026] The protective layer 1 is a film body material made of PET film or PE film, and the weight per square meter of the protective layer 1 itself is in the range of 40 g / ㎡ to 120 g / ㎡. The function of limiting the material of the protective layer 1 is to form a supporting effect on the dressing layer 2 and the adhesive layer 4 to facilitate application. The release layer 5 is a paper material made of glassine release paper or CCK release paper, and the weight per square meter of the release layer 5 itself is in the range of 40 g / ㎡ to 120 g / ㎡. The function of limiting the material of the release layer 5 is to protect the adhesive layer 4, thereby preventing the pressure-sensitive adhesive from being contaminated and affecting the adhesive use effect on the skin surface. Moreover, under the design of the paper material of the release layer 5, it can also play a transient high-temperature resistance effect on the wax dripping work of the wax dripping point 53 when fixing one end of the traction wire body 52 on the surface of the release layer 5 by using the wax dripping point 53.

[0027] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
