Solid polysaccharide materials for use as wound dressings

摘要

Solid, bioabsorbable materials for use as wound dressings comprise at least 50% by weight of a mixture of xanthan and at least one galactomannan, such as guar gum or locust bean gum. The weight ratio of xanthan: total galactomannans is in the range 1:99 to 99:1, preferably 10:99 to 99:10. The material is preferably made in the form of a sponge by freeze drying a mixed aqueous gel of the xanthan and galactomannans.
