Antibacterial and anti-inflammatory membrane

Abstract

The invention discloses an antibacterial and anti-inflammatory membrane, which is mainly prepared from the following raw materials in parts by mass: 7-11 parts of fructus gardeniae, 6-10 parts of coix seeds, 11-15 parts of radix rubiae, 13-17 parts of rhizoma bletillae, 9-17 parts of concha arcae, 8-12 parts of dried orange peel, 7-10 parts of fistular onion stalk, 9-13 parts of herba violae, 6-12 parts of rhizoma cimicifugae, 13-16 parts of longstalk condorvine herb, 11-14 parts of cortex moutan, 40-60 parts of carboxymethyl chitosan, 10-20 parts of hyaluronic acid, 4-8 parts of lysozyme, 1-5 parts of polyvinyl alcohol, 1-4 parts of polyhexamethylene biguanidine hydrochloride and 2-5 parts of menthol. The membrane prepared by the invention has good absorptivity, and the membrane is well bonded to a wound surface and non-adhesive to wound; and the membrane is loaded with active ingredients of traditional Chinese medicines, so that the membrane, besides excellent antibacterial and anti-inflammatory effects, also has functions of stopping bleeding and removing stasis, cooling blood and relieving swelling, and the like; and the membrane is good in biocompatibility to the wound surface, conducive to wound healing and is capable of inhibiting hyperplastic scars.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to an antibacterial and anti-inflammatory film. Background technique [0002] In daily life and work, our skin is often damaged by external injury factors (such as surgery, external force, heat, electric current, chemical substances, low temperature) and internal factors (such as local blood supply disturbance, etc.). Often accompanied by disruption of skin integrity and loss of a certain amount of normal tissue, at the same time, the normal function of the skin is impaired. After the tissue loss is caused, the local tissue is repaired through regeneration, repair, and reconstruction. In the process of wound healing, there will be hyperplasia of granulation tissue and formation of scar tissue, and there will be pathogenic microorganisms in the process, which will cause skin infection and make the wound difficult to heal. Once the wound is not well healed, it will cause great harm to...
