The invention relates to a medical bleeding-stopping and disinfecting biological dressing which can be used inflammation eliminating, bleeding stopping, bacteria resisting, disinfecting, dampness removing, adhesion preventing, skin tissue healing promoting, and skin tissue reparation of various wounds. There are a lot of existing medical dressing products, and most of the existing medical dressing product provides bleeding-stopping functions with a compression hemostasis principle. Bleeding stopping is achieved with platelets and coagulation promotion factors in human blood. Therefore, populations with less platelets and coagulation promotion factors can hardly stop bleeding by merely using common bandages. Also, wound disinfection and antibacterial treatments depend on disinfection product with high irritation to wounds. Traditionally, bacteria and viruses are isolated by using bandages after pre-disinfection. Irritation is caused to skin, cornea and conjunctiva, and muscle. Also, toxicity is caused to keratinocytes and fibroblasts. Therefore, traditional dressings have poor biological safety. The biological dressing provided by the invention is a pure biological preparation which is prepared through strict screening and formulation according to experiments. The dressing provides good bleeding-stopping and disinfecting effect, and has the advantages of wound surface protection, infection prevention, healing promotion, simple application, convenient carrying, good air permeability, reliable treatment effect, convenient manufacturing and application, no chemical addition, no side effect, no irritation or harm to skin, and suitability for various types of skins.
