The invention discloses a preparation method of medical konjac glucomannan antibacterial dressing, which comprises the steps of preparing nano-silver aqueous solution by adopting a water phase reduction method, and then adding sodium hydroxide to prepare nano-silver base solution; adding the mixture of the konjac fine powder and the anhydrous sodium sulfate into the nano-silver base solution, fully dissolving and expanding to form gel, freezing and thawing the gel to prepare the konjac glucomannan medical antibacterial sponge, and then cutting, packaging and performing radiation sterilization to obtain the konjac glucomannan medical antibacterial dressing. The medical konjac glucomannan antibacterial dressing prepared by the method has good hardness and elasticity, uniform pores and good water absorption performance, has stronger inhibition on escherichia coli, staphylococcus aureus and bacillus subtilis, has good biocompatibility with a human body, and has no adverse side effect. The preparation method has the advantages of simple preparation process, high reaction efficiency, low equipment requirement and low production energy consumption, and is suitable for industrial production. |
