International ClassA61F 005/00Foreign Application Priority Data1992-03-27 DKAbstractA heat dressing for treatment of skin areas and comprising a heat generating unit and a liquid-absorbing adhesive layer which prior to use is coated with a strippable release layer. The adhesive layer is preferably of a hydrocolloidal material and may optionally contain one or more medicaments or be coated with alginate fibre mats. The heat generating unit generates heat preferably by means of galvanic or chemical energy, and the heat dressing may further comprise elements for controlling the heat development and/or the surface temperature.Field of SearchWith light, thermal, or electrical applicationSkin or wound facing adhesive layer System for adhesive layer release (e.g., release sheet) Skin laceration or wound cover Wound contact surface Having means for cooling or heating body, treating or collected material or device Electric means Means for cooling or heating material Combined with other radiant or wave energy source (e.g., electromagnetic, thermal, microwave etc.) | |
