Abstract
According to the present invention, a temperature controlled therapy device is provided which maintains a desired temperature in a fluid. The temperature controlled therapy device includes a fluid reservoir, a temperature controlled fluid, a watertight blanket having an internal space located therewith, a conduit connected between an exit port of the reservoir and an entry port of the blanket and between an exit port of the blanket and an entry port of the reservoir for defining a fluid circuit within which the temperature controlled fluid may circulate, a pump for circulating the temperature controlled fluid through the fluid circuit, a differential temperature sensor for generating an output signal proportional to a difference in fluid temperature in the blanket and a temperature at a remote location, an absolute temperature sensor for generating an output signal proportional to the temperature at the remote location, a control circuit having as inputs the outputs of the differential temperature sensor and the absolute temperature sensor for generating a control signal for operating the pump in order to maintain a defined temperature range in the fluid in the blanket, and a power supply for supplying power to the device.
