Claim 18:
19. A cold therapy device comprising:
a reservoir container configured to contain a coolant;
a reservoir coolant mixing chamber positioned within said reservoir container;
a cover positioned within said reservoir container and enclosing said reservoir coolant mixing chamber, said cover dividing said coolant in said reservoir container into a primary volume of coolant external to said cover within said reservoir container and a secondary volume of coolant internal to said cover within said reservoir coolant mixing chamber, wherein said primary volume of coolant is made up of a cold reservoir coolant at a cold reservoir coolant temperature and said secondary volume of coolant is made up of a coolant inlet mixture at a coolant inlet mixture temperature greater than said cold reservoir coolant temperature, wherein said coolant inlet mixture includes a warmed reservoir coolant and a portion of said cold reservoir coolant mixed together in said reservoir coolant mixing chamber, wherein said warmed reservoir coolant has a warmed coolant outlet temperature greater than said coolant inlet mixture temperature, wherein said coolant inlet mixture has a coolant inlet ratio and said coolant inlet ratio and said coolant inlet mixture temperature are defined by relative proportions of said warmed reservoir coolant and said cold reservoir coolant in said coolant inlet mixture, wherein said cover has a plurality of coolant openings formed therein enabling said portion of said cold reservoir coolant to enter said reservoir coolant mixing chamber from said primary volume of coolant external to said cover, and wherein said cover is submersible in said primary volume of coolant;
a coolant pump having a coolant pump inlet and a coolant pump outlet, wherein said coolant pump inlet is positioned within said reservoir coolant mixing chamber and is submersible in said coolant inlet mixture;
a coolant discharge for said warmed reservoir coolant, wherein said coolant discharge is positioned within said reservoir coolant mixing chamber and is submersible in said coolant inlet mixture;
a coolant outlet line connected to said coolant outlet port and said coolant discharge;
a coolant inlet line connected to said coolant pump outlet and said coolant inlet port;
a warmed reservoir coolant flowpath extending from said pad flowpath through said coolant outlet port, said coolant outlet line and said coolant discharge to said reservoir coolant mixing chamber, thereby enabling flow of said warmed reservoir coolant from said pad flowpath to said reservoir coolant mixing chamber;
a coolant inlet mixture flowpath extending from said reservoir coolant mixing chamber through said coolant pump inlet, said coolant pump, said coolant pump outlet, said coolant inlet line and said coolant inlet port to said pad flowpath, thereby enabling flow of said coolant inlet mixture from said reservoir coolant mixing chamber to said pad flowpath; and
a diverter panel in said cover wherein said diverter panel is continuously fluid-impermeable and free of any coolant openings and is positioned adjacent to said coolant discharge and oriented relative to said coolant discharge and said coolant pump inlet such that said warmed reservoir coolant is dispersed from said coolant discharge in a direction away from said coolant pump inlet and is redirected in an opposing direction back toward said coolant pump inlet by said diverter panel.
