WOUND DRESSINGS

摘要

A wound dressing is characterised in that the wound-contacting surface thereof comprises carboxymethyl cellulose filaments capable of absorbing at least 15 times their own weight of 0.9 % by weight aqueous saline solution (as measured by the free-swell absorbency test) to form a swollen transparent gel. The dressing when thus swollen to form a transparent gel retains sufficient fibrous character to be removed as a coherent dressing from a wound. The carboxymethyl cellulose filaments can be used to treat a traumatic surgical or chronic wound.
