Patent

CA 2109672

ABSTRACT WOUND DRESSING The invention provides wound dressings comprising a molecular filtration membrane having a maximum pore size in the range of from 0.001µm to 0.5µm, and preferably in the range of from 0.01µm to 0.25µm. The wound dressings may also comprise an absorbent layer atop the molecular filtration membrane and/or a wound contact layer of wound-friendly bioabsorbable material for contacting the wound. In use, the molecular filtration membrane retains high molecular weight biopolymers and wound healing factors at the wound surface while excluding bacteria and allowing rapid egress of wound exudate through the membrane into the absorbent layer.
