Abstract
A non-contact controllable heater wound covering and method having a peripheral sealing ring covered by a layer to which is attached a heater and this assembly is attached to the skin with an adhesive so that the heater is held proximate the wound area in a non-contact position. The layer and peripheral sealing ring together define a treatment volume proximate the wound. The wound covering includes a programmable active heater control and the sealing ring may dispense water to control the humidity of the treatment volume. One form of active heat is an electrical resistive filament in variable geometric shapes providing versatility in application of heat to different types of wounds and wound area geometries. Another form of active heat is the transfer of a heated gas to the wound covering.
