摘要： A wound dressing comprising acylated chitosan fibre. The dressing has a wet strength of 0.3 N/cm or above. The acylated chitosan fibre may have a degree of substitution of 0.10-0.50. The acylated chitosan fibre may preferably have a degree of substitution of 0.20-0.40. The dressing may have an absorbency of 5-25g/g of a solution containing 8.298g/l of sodium chloride and 0.368 g/l of calcium chloride dehydrate as measured by BSEN 13726-12002 Part 1 Aspects of Absorbency. The base material of the dressing may be chitosan fibre that has been chemically modified through an acylation process using anhydride and ethanol as the solvent. A method of manufacturing the wound dressing involves reacting chitosan fibre with anhydride and making acylated chitosan felt through a nonwoven process, and through cutting, packing and sterilizing processes.

摘要： The present invention provides a 3-layered wound dressing comprising two outer layers fabrics and one middle layer fabric. The density of the said two outer layer fabrics is greaterthan that of the middle layer. The weight of the two outer layerfabrics is between 8-140 gsm, density 0.08-0.32 g/cm3. The said dressing provides a good fluid and moisture retention property, allowing a large amount of wound exudates to be absorbed and contained within the middle layer and preventing the absorbed wound exudates to contaminate healthy skin.

摘要： The present invention discloses a 3-layered wound dressing and its method of manufacturing. The dressing comprises a wound contact layer, absorbent middle layer and outer layer. The said wound contact layer is a nonwoven made of a blend of hydrophilic fibres and hydrophobic fibres. The said absorbent middle layer is also a nonwoven made of another blend of hydrophilic fibres and hydrophobic fibres. The said outer layer is a hydrophobic nonwoven. The said wound dressing can transfer the fluid vertically so that the wound exudates can be absorbed and transferred to the middle layer, preventing the maceration of the surrounding skin. The said wound dressing can be used in the management of chronic wounds, particularly for heavy draining wounds.
