  • Patent number: 11129847
    Abstract: An antibacterial wound dressing, a method for preparing the antibacterial wound dressing, and a use of the antibacterial wound dressing are provided. The antibacterial wound dressing is obtained by amidating carboxymethyl cellulose with a guanidine compound. The carboxymethyl cellulose has a substitution degree of 0.1-0.6, and the guanidine compound has a grafting degree of 0.2%-10.0%.

  • Patent number: 11131040
    Abstract: The present disclosure provides an antimicrobial alginate fiber, a method for manufacturing an antimicrobial alginate fiber dressing thereof, and an application thereof. When the cationic polymer polyhexamethylene guanide salt is mixed with the anionic polymer alginate, the antimicrobial activity of the guanide salt is quickly passivated. The present disclosure achieves a lower content of polyhexamethylene guanide salt in an alginate dressing with good long-term antimicrobial activities. The polyhexamethylene guanide salt has a low dissolution rate, and significantly reduces a potential risk of carcinogenicity, mutagenicity and reproductive toxicity.
