Problems solved by technology

[0003] With the deepening of the research, we found that in order to improve the antibacterial performance of the gel dressing, antibacterial particles are generally added to the gel in the prior art, but the pure physical doping is used to cover it with the gel. Easy to fall off, the actual antibacterial performance cannot be guaranteed

Abstract

The invention discloses a repairing dressing containing ginseng extract and a preparation method thereof, wherein the main components are functionalized chitosan, oxidized sodium alginate, chitosan microspheres, plant extracts and other components to prepare A repair dressing containing ginseng extract with excellent antibacterial properties was obtained; a hydrogel was prepared with functionalized chitosan and oxidized sodium alginate as the main components, and the whole hydrogel presented a porous network, which was beneficial to The slow release effect of chitosan microspheres and plant extracts; the application introduces plant extracts, which are ginseng extracts and centella asiatica extracts, which can facilitate skin absorption on the one hand, and plant extracts also It has anti-inflammatory and antibacterial effects, improves the antibacterial properties of repair dressings, and avoids wound inflammation. The process design of the invention is reasonable, and the prepared repair dressing not only has excellent antibacterial performance, but also has excellent water retention and moisturizing performance, and can effectively promote wound repair.

Description

technical field [0001] The invention relates to the technical field of dressings, in particular to a repair dressing containing ginseng extract and a preparation method thereof. Background technique [0002] Hydrogel dressing is one of the more common dressings on the market. It is generally suitable for the repair of epidermal defect wounds, painful wounds and other wounds. When used, hydrogel dressings can provide a moist environment for the wound to promote wound healing. At the same time, it can absorb wound exudate and relieve wound pain. [0003] With the deepening of research, we found that in order to improve the antibacterial properties of gel dressings, antibacterial particles are generally added to the gel in the prior art. It is easy to fall off, and the actual antibacterial performance cannot be guaranteed. [0004] Based on the above situation, we disclose a repair dressing containing ginseng extract and a preparation method thereof, which have solved the tec...
