Abstract

The invention relates to the technical field of medical supplies, and in particular relates to a medical antimicrobial dressing and a preparation method of the medical antimicrobial dressing. The medical antimicrobial dressing is prepared from the following raw materials in parts by weight: 55-65 parts of sodium carboxymethyl cellulose, 45-50 parts of sodium alginate, 20-35 parts of stearic acid,10-14 parts of nanometer titania, 8-12 parts of sodium carbonate, 15-18 parts of polylactic acid, 10-15 parts of polyethylene glycol, 2-6 parts of glycerol, 5-8 parts of mannose, 7-10 parts of sweet potato starch, and 0.3-3.3 parts of an antimicrobial agent. The prepared antimicrobial dressing has good biocompatibility, can be gradually absorbed by the body, is good in hydrophility and moisture absorption, provides a suitable moist rehabilitation environment for the wound, is easy to remove, causes no adhesion to the wound, can promote the rapid heal of the surface of the wound, can regulate the immune system, can promote the heal of the surface of the wound, is good in inflammation-resisting effect, can effectively prevent wound infection, belongs to an excellent antimicrobial material used for the surface of the wound, is low price, and is wide in source.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a medical antibacterial dressing and a preparation method thereof. Background technique [0002] Biomedical polymer materials are non-living polymer materials used for the diagnosis, treatment, repair or replacement of biological tissues or organs for physiological system diseases, and to enhance or restore their functions. In living matter, protein, muscle, cellulose, starch, and various biological enzymes are all polymer compounds. Therefore, the structure and physical and chemical properties of artificially synthesized polymer materials are closest to those of living organisms, and they are ideal biomedical materials. Polymer materials have the characteristics of rich sources, various varieties, easy storage, wide range of variable properties, and easy processing. [0003] Antibacterial concepts, technologies and products have been widely used in daily life. For medi...
