Patent ID: 7211104

Claim:
A contrast therapy system comprising: a hot reservoir for holding a relatively hot fluid; a cold reservoir for holding a relatively cold fluid; a mixing valve for receiving a selected ratio of the hot and cold fluids from the hot and cold reservoirs and operable to deliver a therapy fluid with a therapy temperature determined by the selected ratio; and a therapy pad for receiving the therapy fluid from the mixing valve and returning the therapy fluid to at least one of the hot reservoir and the cold reservoir; wherein the therapy pad is one of a plurality of therapy pads, each therapy pad configured to individually couple to the mixing valve via a fluidic coupling assembly, and wherein at least two of the plurality of therapy pads are differently configured relative to one another; further wherein, each therapy pad comprises: an active thermal exchange bladder, wherein the active thermal exchange bladder is defined by a perimeter including indentations whereby said indentations are configured to allow the bladder to achieve a close fit at a therapy site when said bladder is under fluid pressure; a stretchable bladder envelope including a first face and an opposing second face, the faces converging at a perimeter of the envelope and collectively defining a deformable volume adapted to receive the thermal exchange bladder and compress the thermal exchange bladder around the therapy site; and an adjustable strapping system coupled to the bladder envelope and adapted to secure the bladder envelope in a fitted position adjacent the therapy site, wherein the first face includes mesh, and the second face includes stretchable loop material configured to releasably receive complementary hook material.
