Abstract
A thermal blanket particularly suitable for post-operative therapy and a thermally-conductive, fluid-absorbing interfacing pad for use therewith. The pad includes an intermediate or core layer of a pliant, liquid-absorbing, hydrocolloid-containing skin barrier material having both wet and dry tack, a thin backing layer on one side of the intermediate layer, and a porous, fluid-transmitting (and preferably fluid-absorbing) facing layer on the opposite side of the intermediate layer. One or more adhesive patches detachably secure the blanket and pad together, such patches being formed of a pressure-sensitive adhesive material preferably having greater affinity for the surface of the blanket than for the surface of the backing layer of the pad. In one embodiment, the pad's facing layer is provided with openings that expose areas of the adhesive intermediate layer for direct contact between the intermediate layer and a patient's skin.
