Abstract

The invention discloses a trauma patch for treating chronic trauma and belongs to the technical field of preparation of medical applied materials. The trauma patch is composed of a three-layer structure of a substrate cloth layer, a seaweed sponge layer and a spin silk treating layer. The spin silk treating layer is composed of three layers of coaxial spin silk, the spin silk of the first layer is internally provided with a golden cypress extract, the spin silk of the second layer is internally provided with a fibroblast growth factor, and the spin silk of the third layer is internally provided with borneol. The trauma patch for treating the chronic trauma accords with a 6864 medical hygienic material and applied material and a 6866 medical high molecular material and product, and referring to the secondary medical treatment appliance product standard, the trauma patch has the therapeutic function and is capable of diminishing inflammation, promoting granulation and recovering tissue growth for traumatic skin and suitable for treating of general trauma and the chronic trauma.

Description

technical field [0001] The invention belongs to the technical field of preparation of medical dressings, in particular to a bandage suitable for general wounds and chronic wounds. Background technique [0002] Trauma can be classified according to location, site of injury, injured tissue, causative agent, and degree of skin integrity. According to the location of occurrence, it can be divided into war injuries, industrial injuries, agricultural injuries, traffic injuries, sports injuries, life injuries, etc.; According to the type of injury, it can be divided into fracture, dislocation, concussion, organ rupture, etc.; those who are injured at the same time in adjacent parts are called joint injuries; when classified according to the injured tissue or organ, it can be divided into soft tissue trauma, trauma, etc. according to the depth of the injured tissue. Bone and joint trauma and visceral trauma. Soft tissue trauma refers to damage to the skin, subcutaneous tissue, and...
