The invention relates to a pain relieving type double-layer artificial skin which comprises a dermis layer and an epidermis layer attached to the dermis layer, wherein the dermis layer is a blended nanofiber layer formed by bioactive material nanofibers and polyurethane nanofibers, the epidermis layer is an expanded polytetrafluoroethylene layer, the blended nanofiber layer and the polytetrafluoroethylene layer are both porous structure layers, the bioactive material nanofibers comprise a skin layer and a core layer, the skin layer is a bioactive material, and the core layer is a pain relieving type medicine. The artificial skin has drug slow release function, and the carried pain relieving drug can relieve pain of patients with skin defect, and reduce influence of pain on patients. |
