Medical pad and system for thermotherapy

A medical pad for contact and thermal exchange with a patient, comprising:

• a fluid circulation layer for containing a thermal exchange fluid circulatable therethrough;
• a first port fluidly interconnected to the fluid circulation layer for circulating the thermal exchange fluid into the fluid circulation layer;
• a second port fluidly interconnected to the fluid circulation layer for circulating the thermal exchange fluid out of the fluid circulation layer;
• and,
• a hydrogel layer interconnected to and extending across one side of the fluid circulation layer to define an adhesive surface for adherence to a patient's skin, wherein said hydrogel layer comprises an ultra violet light-cured composition that includes:
• a cross-linking copolymer in an amount of between about 15% to 30% by weight of said composition;
• water in an amount of between about 15% to 40% by weight of said composition;
• and,
• glycerol in an amount of between about 25% to 35% by weight of the composition;
• wherein said hydrogel layer has a thermal conductivity of at least about 1.9 cal/hr-cm-° C.
