[0002] Honey itself contains a lot of enzymes and various nutrients needed by human cells, tissues and organs, and can generate a lot of heat without fat. It contains effective bactericidal and hemostatic components, which can be used to assist in the treatment of external wounds. A high-quality medical product, but at present domestic honey products are mainly taken orally, and there are very few honey products used for medical external application. Therefore, a product and its preparation method that can fill the gap in honey medical external application are very useful practical value

Abstract

The invention provides a wet wound dressing. The wet wound dressing comprises a back pasting layer, a dressing core and a protective layer. The dressing core is arranged between the back pasting layer and the protective layer, and the back pasting layer is formed by laminating a preservative film and a PU film. The dressing core comprises non-woven fabric and composite honey powder, wherein the non-woven fabric is coated with the composite honey powder, the non-woven fabric is attached to one face of the PU film, and the composite honey powder is attached to one face of the protective layer. The invention further provides a preparation method of the wet wound dressing. Manuka honey is adopted as the core component of the wet dressing, the honey contains antibiotic constituents UMF, the dressing has good antibiotic performance, and vitamins, sodium carboxymethylcellulose, growth factors and an antibacterial agent capable of promoting wound healing are introduced. The wet wound dressing has the advantages of being soft, good in ductility, good in attachment performance and the like, and has good application potential.
