Abstract: The present disclosure relates generally to tubular wound dressings that include a superabsorbent component that can be used to treat exuding wounds. The tubular wound dressings may include a superabsorbent component sandwiched between two tubular elastic and resilient components. Alternatively, the dressing may be concentrically arranged to include at least three components, including a superabsorbent component, and two elastic and resilient components. Also disclosed herein are kits including the tubular wound dressings of the present technology, and instructions for use.

Abstract: An anti-microbial absorbent chitosan, optionally in the form or fibres, derivatised by reaction with an optionally substituted alkylene oxide, a non-woven fabric and an absorbent device comprising the derivatised chitosan, methods for the preparation of such a chitosan, non-woven fabric and an absorbent device, and the use of said absorbent device in wound care.

Abstract: A process for producing a salt of a chitosan acid anion derivative, which comprises contacting chitosan fibre (a) with a base in an aqueous or non-aqueous medium and (b) with a solution in an aqueous or non-aqueous medium of a salt of the formula (I): M-R-T wherein M is a Group IA metal cation; R is a hydrocarbyl oxoacid anion, substituted by T; and T is a nucleophilic leaving group, all at a temperature below 50° C., preferably in the range of 30 to 40° C.

Abstract: An anti-microbial absorbent chitosan, optionally in the form or fibres, derivatised by treatment with high energy, in particular gamma, radiation, a non-woven fabric and an absorbent device comprising the derivatised chitosan, methods for the preparation of such a chitosan, non-woven fabric and an absorbent device, and the use of said absorbent device in wound care.

Abstract: A two layer bandage includes a padding layer; and an elastic layer, wherein the padding layer which includes a nonwoven material, and wherein fixing of filaments in the nonwoven material is implemented solely via needling and the padding layer is fixed to the elastic layer solely by needling.
