COLD THERAPY DEVICE WITH THERMO-MECHANICAL MIXING VALVE

摘要

A cold therapy unit incorporates a cold reservoir containing a cold treatment fluid, typically water with ice and a treatment pad with an inlet line and an outlet line. A thermo-mechanical mixing valve receives treatment fluid from the reservoir and warmer fluid from the pad in a ratio that results in treatment fluid of the desired temperature. A pump delivers that treatment fluid to the inlet line on the pad. A portion of the treatment fluid exiting the pad through an outlet line will return to the reservoir and a portion to the mixing valve as required to maintain a predetermined temperature in the mixing valve.

1. A cold therapy unit comprising:
a reservoir containing a cold treatment fluid; a treatment pad with an inlet line and an outlet line; a thermo-mechanical mixing valve receiving cold treatment fluid from the reservoir through a first inlet port and fluid from the pad outlet line through a second inlet port, said thermo-mechanical mixing valve reactive responsive to temperature to mix fluid from the reservoir and fluid from the pad outlet line in a ratio to provide fluid at a predetermined temperature to a valve outlet port; a pump attached to the valve outlet port and the pad inlet line to deliver the mixed treatment fluid from the mixing valve to the pad; and a conduit interconnecting the pad outlet line and the reservoir.
