摘要： The present invention relates to a wound care device, and more specifically to an absorbent wound care device and a method for making the same. The wound care device is obtainable by bringing together a first material and an acidic substance to form an intermediate device, which first material does not substantially gel when exposed to a fluid but does gel when brought together with an acidic substance and exposed to a fluid, and exposing the intermediate device to ethylene oxide.

摘要： The present invention relates to a process for producing a low endotoxin alkali chitosan, and also to a process for producing low endotoxin neutral chitosan, chitosan salt and chitosan derivatives, and to the products of such processes. The process comprises contacting chitosan with an alkali solution to form a mixture and leaving the mixture for at least about 12 hours. The low endotoxin alkali chitosan may be used in the manufacture of other useful chitosan based products.

摘要： 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.

摘要： The present invention relates to a wound dressing composition for use as or in a wound dressing and to methods of making the wound dressing composition. The wound dressing composition comprises an absorbent material, an adhesive material and an anchor material attached to the absorbent material and the adhesive material. The anchor material is operable to maintain a link between the absorbent material and the adhesive material when the wound dressing composition is wet.
