The cold therapy unit of this invention includes a small portable ice chest and an electronic control unit to provide a unit which is safe to use right after surgery and has a portion which may be taken home by the patient. The combined unit provides the safety and accuracy of an institutional unit and the practicality and affordability of a portable take home unit. The cold therapy device includes an electronic control unit similar to the current institutional units in that it includes a thermoelectric module along with its associated electronic controls and a pump. The electronic control unit includes couplings to connect hoses leading to the patient and the cooling pad. Further, the portable ice chest having a lid fitted with an electric fluid pump which includes quick connect couplings allowing the ice chest to be placed in fluid communication with the electronic control unit. Finally, the fluid pump is electrically connected to the electronic control unit.

[ We claim:] [3.] A small portable cold therapy unit having a reservoir for holding a quantity of liquid, a first pump extending into the reservoir for pumping fluid from the reservoir, a hose set and pad connectable to the pump for receiving fluid pumped from the first pump and returning it to the reservoir after the fluid has traveled through the pad, the cold therapy unit removably connected to an electronic control unit having a second pump such that the electronic control unit is in flow communication with the pad and hose set and monitors the temperature of the liquid relative to a predetermined set point, wherein if the electronic control unit senses that temperature of the liquid exceeds the predetermined set point the control unit turns on the first pump in the portable cold therapy unit to reinfuse the liquid within the pad and hose set with a quantity of chilled liquid.
