Abstract

The invention relates to a wound plaster. The wound plaster comprises a sterilizing film, a protective film covering the sterilizing film and adhesive tapes connected with the two ends of the sterilizing film, wherein the sterilizing film comprises graphene or graphene oxide and a traditional Chinese medicine composition, the traditional Chinese medicine composition comprises radix notoginseng, herba taraxaci, flos lonicerae, herba lobeliae chinensis, nepal dock root, herba rabdosiae and folium isatidis, and the graphene or graphene oxide contains active functional groups. The wound plaster has a very good bleeding arresting effect, swelling reducing and pain easing effects, scar removing effect and sterilizing effect, has great progress in use effect and has popularization and applicationvalues.

Description

technical field [0001] The invention relates to the field of medical and sanitary materials, in particular to a band-aid and its preparation method and application. Background technique [0002] Band-aid is the most commonly used surgical drug in people's life. Band-aid, also known as "hemostatic plaster", has the functions of hemostasis and skin protection. Wrapping the wound for a long time will make the wound and the skin around the wound turn white and soften, leading to secondary infection of bacteria. This will make the wound worse. [0003] The Chinese patent publication number is CN104445155A, and the title of the invention is a carboxyl functionalized graphene material and its preparation method. It discloses the preparation of carboxyl function and graphene material. The preparation process of the method is simple, the cost is low, and it can be prepared under mild conditions. A carboxyl-functionalized graphene material, the prepared carboxy-functionalized graph...
