More Information
Summary:Provided is a microneedle patch (1) comprising a substrate part (12) and multiple needle parts (11) protruding from the substrate part (12). The substrate part (12) consists of a diffusion-proof layer and a base, and each needle part (11) consists of a needle tip (111), a diffusion-proof layer and a base. The diffusion-proof layer of each needle part (112) is formed between the needle tip (111) and the base of the corresponding needle part (113). The diffusion-proof layer of the substrate part (122) and the diffusion-proof layer of needle part (112) are one-piece structures, and so are the base of the substrate part (123) and the base of the needle part (113). The diffusion-proof layer can prevent the active ingredients from diffusing to the base, limit the active ingredients to the needle tip and control the carrying quantity thereof.
