Preparation method of antibacterial dressing

Abstract

The invention discloses a preparation method of an antibacterial dressing. The preparation method comprises the following steps of weighing the following raw materials, by weight, 25-35 parts of a 15% silver nitrate solution, 10-20 parts of plant fibers, 1-5 parts of polyvinylpyrrolidone, 3-8 parts of an antibacterial precursor and 50-80 parts of deionized water; heating the silver nitrate solution and the plant fibers to 120-130 DEG C, keeping the temperature and reacting for 30 minutes, cooling, washing with deionized water for three times, drying to obtain composite fibers, and cooling to room temperature; preparing the composite fibers into carbonized fibers; and adding the polyvinylpyrrolidone into the deionized water, carrying out magnetic stirring for 30 minutes at the rotating speed of 100-150r / min, preparing a polymer aqueous solution, adding the antibacterial precursor and the carbonized fibers, drying, preparing a primary material, washing for three times, and preparing the antibacterial dressing. The dressing plays an antibacterial effect through the silver ions and the antibacterial precursor, the components are environment-friendly, and residues cannot pollute the environment.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, in particular to a preparation method of an antibacterial dressing. Background technique [0002] Traditional wound dressings include gauze, absorbent cotton, bandages, etc. However, from a medical point of view, these traditional wound dressings have limited clinical application because they do not have the properties of treating and repairing wounds, nor do they have antibacterial activity. Therefore, new medical dressings that can promote wound healing, have high antibacterial properties and are more convenient to use have gradually developed. What play a decisive role in these wound dressings are the various antibacterial agents with antibacterial effects contained in the dressings. Different components in the antibacterial agent will play a key role in the healing effect of the wound. How to provide an antibacterial dressing that has high antibacterial properties and is beneficial...
