Polygonatum polysaccharide dressing and preparation method of finished product thereof

Abstract

The invention provides a polygonatum polysaccharide dressing and a preparation method of a finished product thereof. Every 100 g of the polygonatum polysaccharide dressing comprises 5-10 g of polygonatum polysaccharides, 1-4 g of antibacterial peptide, 6-15 g of polyethylene glycol 400 and the balance of purified water. The preparation method of the polygonatum polysaccharide dressing comprises steps as follows: firstly, sequentially adding the polygonatum polysaccharides, the polyethylene glycol 400 and the purified water to a reaction container, heating the mixture for dissolution, stirring the mixture for cooling, then dissolving the antibacterial peptide in the purified water, adding an obtained solution to the reaction container in the last step, and performing heating, even stirring, cooling, filtering and defoaming to obtain the polygonatum polysaccharide dressing; finally, directly canning the polygonatum polysaccharide dressing to prepare polygonatum polysaccharide gel, or evenly spraying the polygonatum polysaccharide dressing on surface layers of sanitary napkins, and performing vacuum freeze-drying to prepare gynecological protection pads. The provided polygonatum polysaccharide dressing can keep wound surfaces wet, cannot cause secondary damage to wounds during dressing replacement and can effectively prevent bacterium invasion and wound infection, the preparation technology is simple, and a few of raw materials are needed.

Description

technical field [0001] The invention relates to an antibacterial and anti-inflammatory liquid dressing and a preparation method of the finished dressing. Background technique [0002] Wound healing techniques include dry healing and wet healing. Dry healing generally allows the wound to scab, the scab falls off, and the underlying wound heals. However, if there is fluid under the scab or the scab does not fall off, it will be difficult to heal; wet wound healing techniques It is to make the wound never scab, flatten the granulation directly, grow a layer of membrane to cover the wound, and finally heal. Because the wound is always in a moist state, it is called wet healing. A humid environment can speed up the migration of wound epidermal cells. , to prevent the epidermal cells from migrating around the scab and prolong the healing time, stimulate the formation of capillaries, promote the growth of fibroblasts and endothelial cells, and thus make the wound heal quickly.
