A kind of improved Medical napkin contact heat exchange and patient include fluid circulation wait include heat-exchange fluid belt there, the fluid circulation layer that enters and leaves of first port and second port circulation heat-exchange fluid is interconnected to the side of hydrogel layer and extends across fluid circulation layer and adhered on patient skin with limiting bonding surface. Hydrogel layer include ultraviolet photo-curing composition, it includes the amount of cross-linked copolymer about 15% to 30% weight composition, the amount of water be about 15% to 40% weight composition and glycerol amount about 25% to 35%. Hydrogel layer, which provides, has thermal conductivity at least about 1.9 ca//hr-cm-°C.
