Abstract
A non-contact wound covering for covering a wound. A peripheral sealing ring is covered by a barrier layer and this assembly is attached to the skin with an adhesive. The barrier layer and peripheral sealing ring together define a treatment volume over the wound. The barrier layer may include active and passive heaters and the sealing ring may dispense water to control the humidity of the treatment volume. One form of active heat is the transfer of a heated fluid to the wound covering.
