Claim Text:
1. A thermal contrast therapy device comprising: a cooling system comprising a first pump configured to circulate cold fluid through a cooling block via a cold fluid recirculation line that provides fluid communication with a cooling block inlet, and a heating system comprising a second pump configured to circulate hot fluid through a heating block via a hot fluid recirculation line that provides fluid communication with a heating block inlet; wherein, the first pump is further configured to circulate cold fluid through a treatment pad via an outflow fluid line while the second pump circulates hot fluid through the heating block with at least a portion of said hot fluid bypassing the treatment pad via the hot fluid recirculation line, and the second pump is further configured to circulate hot fluid through the treatment pad via the outflow fluid line while the first pump circulates cold fluid through the cooling block with at least a portion of said cold fluid bypassing the treatment pad via the cold fluid recirculation line, in a sequence of alternating cooling periods and heating periods; and a shared reservoir configured to allow fluid to flow by gravity to: the cooling system via a first supply line providing fluid communication between the cooling system and the shared reservoir, the first supply line configured to allow fluid to flow by gravity to the cooling system in proportion to a corresponding volume of fluid having left the cooling system; and the heating system via a second supply line providing fluid communication between the heating system and the shared reservoir, the second supply line configured to allow fluid to flow by gravity to the heating system in proportion to a corresponding volume of fluid having left the heating system.
