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.
Claims32
A wound covering for application to a wound area of a patient's body, the wound covering comprising:
- a peripheral sealing ring having an upper surface and a lower surface, and defining an open cavity for placement over and sealing around the wound area;
- a barrier layer spanning the peripheral sealing ring and attached to he peripheral sealing ring proximate the upper surface and spaced apart from the open cavity by the peripheral sealing ring;
- the peripheral sealing ring for supporting the barrier layer above the level of the wound area;
- the peripheral sealing ring and the barrier layer together forming a wound treatment volume;
- wound area attachment means, proximate the lower surface, for permitting attachment to the wound area;
- and
- a heater, proximate the barrier layer for controlling the temperature of the wound treatment volume.
