A kind of medical antibacterial dressing and preparation method thereof

Abstract

The invention provides a medical antibacterial dressing and a preparation method thereof. The dressing comprises the following raw materials: an artemisia sieversiana extract, an aconitum tanguticum extract, chitosan, sodium alginate, collagen, polyacrylic acid, acrylamide, vitamin C, polyethylene glycol, polyvinyl alcohol, calcium chloride, sodium borate, monoammonium phosphate, glycerinum, sorbitol, ethylene glycol, mannose and deionized water. The preparation method comprises the following steps: firstly, respectively preparing the artemisia sieversiana extract and the aconitum tanguticum extract; adding chitosan, vitamin C, calcium chloride, sodium borate and monoammonium phosphate to 1 / 3 of deionized water in parts by weight to obtain mixed liquid I; adding the residual components to the rest of deionized water in parts by weight to obtain mixed liquid II; and finally mixing the artemisia sieversiana extract, the aconitum tanguticum extract, the mixed liquid I and the mixed liquid II, so as to obtain the medical antibacterial dressing. The dressing disclosed by the invention is capable of effectively sterilizing and diminishing inflammation, improving microcirculation of surrounding tissues of the wounds, and playing roles in easing pain, inhibiting bacteria reproduction and repairing wounds.

Description

technical field [0001] The invention belongs to the field of medical equipment machinery, and in particular relates to a medical antibacterial dressing and a preparation method thereof. Background technique [0002] Medical dressings are wound-wrapping supplies, medical materials used to cover sores, wounds or other damages. As a covering for wounds, medical dressings can replace damaged skin to act as a temporary barrier during wound healing, avoid or control wound infection, and provide an environment conducive to wound healing. With the aging population and the increase of chronic ulcerative wounds, the market value of medical dressings is also becoming more and more important. In 1962, the British Winter proposed the "moist wound healing theory", that is, wounds heal faster in a moist environment than in a dry environment, which made a breakthrough in people's understanding of the wound healing process. [0003] Chitosan is the product of partial or complete deacetylat...

AI Technical Summary

Problems solved by technology

[0006] At present, the antibacterial dressings put into clinical production in the industry generally have problems such as unsatisfactory antibacterial effect and poor adhesion to the skin. Therefore, it is still necessary to further improve and improve its antibacterial effect and adhesion to skin tissue.
