Example Embodiment

[0066] Example 1

[0067] An antibacterial and healing-promoting wound dressing is made of the following components by mass percentage: octenidine 0.1%, clove extract 0.1%, Coptidis chinensis extract 0.25%, Scutellaria baicalensis extract 0.15%, polyethylene glycol 4003%, Tween 80 3%, polyvinyl alcohol 17883%, carbomer 9400.1%, cetostearyl caprylate 1%, octadecyl caprylate 3%, disodium EDTA 0.001%, menthol 0.1%, The remainder is purified water.

[0068] In the present embodiment, described clove extract is extracted according to the following steps:

[0069] (1) take the crude drug of cloves, pulverize until it passes through a 20-mesh sieve, add 60% ethanol equivalent to 15 times the weight of cloves, soak for 12h, and heat under reflux for 2h to obtain medicinal residues 1 and filtrate 1;

[0070] (2) add 15 times of 50-75% ethanol to the obtained medicinal residue 1, heat under reflux for 2 h, filter to obtain medicinal residue 2 and filtrate 2, combine filtrate 1 and fil...

Example Embodiment

[0088] Example 2

[0089] An antibacterial and healing-promoting wound dressing is made from the following components: octenidine 0.001%, clove extract 0.5%, Coptis chinensis extract 1%, Scutellaria baicalensis extract 0.7%, polyethylene glycol 400 2.63%, poly Sorbitan 80 0.001%, polyvinyl alcohol 0588 0.001%, carbomer 940 0.877%, cetostearyl caprylate 2.63%, octadecyl caprylate 2.63%, disodium EDTA 0.001%, menthol 0.1 %, sodium hydroxide 0.088, and the balance is purified water.

[0090] In this example, the preparation process of clove extract, Coptis chinensis extract, and Scutellaria baicalensis extract is the same as that of Example 1.

[0091] The preparation process of the wound dressing described in this example is the same as that of Example 1.

Abstract

The invention discloses an antibacterial healing-promoting wound dressing and a preparation method thereof, and relates to the technical field of medical dressings. The antibacterial healing-promotingwound dressing comprises an effective substance and a wound dressing matrix, wherein the effective substances comprise 0.001-0.5% of otinidine and 0.1-5% of a traditional Chinese medicine extract, and the wound dressing matrix comprises 0.5-8% of a thickening agent, 0.1-10% of an emulsifying agent, 0.002-20% of an oil phase, 0.001-1% of a chelating agent and the balance of water. The antibacterial healing-promoting wound dressing disclosed by the invention is small in dosage, and obvious in effects of inhibiting the growth of wound bacteria and preventing infection; the wound dressing is goodin film-forming property and thin in formed film; the wound dressing is convenient to spray and smear, and meanwhile, the functions of wound disinfection and protection are achieved; no pricking feeling of an organic solvent is caused, the mildness is realized, and the compliance is good.

Description

technical field [0001] The invention relates to the technical field of medical dressings, in particular to an antibacterial wound dressing for promoting healing and a preparation method thereof. Background technique [0002] Wound refers to the damage of human tissues or organs caused by physical, chemical and other factors. Its healing is a dynamic and complex process, including coagulation phase, inflammation phase, cell proliferation phase and new tissue remodeling phase. The speed of wound healing is affected by factors such as wound type, pathological conditions, and dressing type. As a temporary skin substitute, dressing can protect the wound, stop bleeding, prevent infection, and more importantly, promote wound healing. [0003] Traditional dressings such as gauze and cotton pads are the main dressings used clinically. However, the hemostatic effect of traditional dressings is unsatisfactory, and there is no moisturizing effect. The granulation tissue is easy to ente...
