  • Improved Medical Pad and System for Thermotherapy
    Publication number: 20240099878
    Abstract: An improved medical pad for contact thermal exchange with a patient includes a fluid circulation layer for containing a thermal exchange fluid circulatable therethrough, a first port and a second port for circulating the thermal exchange fluid in to and 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. The hydrogel layer can include an ultraviolet light-cured composition with a cross-linking copolymer, water, and glycerol. The hydrogel layer is provided to have a thermal conductivity of at least about 1.9 ca/hr-cm-° C.
    Type: Application
