Abstract

The invention discloses an antibacterial adhesive bandage containing zinc oxide nanoparticles and a preparation method thereof, and belongs to the technical field of medical supplies. The prepared adhesive bandage consists of an adhesive backing, a drug layer, a chitosan nonwoven layer and strippable layers. The chitosan nonwoven layer contains nano zinc oxide connected through an immersion method; and medicament containing Chinese herbal medicinal ingredients is attached to the drug layer and includes a field thistle extract, chitosan quaternary ammonium salt, growth factors, amino acid, decavitamin and other ingredients. Thus, the problems that existing adhesive bandages cannot promote wounds to heal can be solved, and the technical effects of promoting the wounds to heal quickly and preventing the wounds from being infected can be realized. The prepared adhesive bandage is simple in manufacturing technology, good in biocompatibility, low in cost, non-irritating to the wounds and safe in product, has no toxic and side effects and can absorb the exudate from the wounds; and the adhesive bandage can be applied to the nursing care of superficial wounds such as small wounds, abrasions and cuts.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to an antibacterial band-aid containing zinc oxide nanoparticles and a preparation method thereof. Background technique [0002] Trauma is the damage of normal skin under the joint action of external injury factors (external force, heat, surgery, electric current, chemical substances and low temperature, etc.) and internal factors of the body (local blood supply insufficiency). The appearance of wounds is generally accompanied by the destruction of skin integrity and the loss of some normal tissues, resulting in impairment of normal skin function. Wound repair is a complex process involving multiple cells and cytokines, and wound dressings play an important role in the process of healing and repairing wounds. When using a dressing to treat a wound, the dressing can isolate external microorganisms, avoid further infection of the wound, and then use its own heali...
