Thermal system with improved user interface

A thermal control unit for controlling a patient's temperature during a thermal therapy session, the thermal control unit comprising:

• a fluid outlet adapted to fluidly couple to a fluid supply line;
• a fluid inlet adapted to fluidly couple to a fluid return line;
• a circulation channel coupled to the fluid inlet and the fluid outlet;
• a pump for circulating fluid through the circulation channel from the fluid inlet to the fluid outlet;
• a heat exchanger adapted to add or remove heat from the fluid circulating in the circulation channel;
• a fluid temperature sensor adapted to sense a temperature of the fluid;
• a patient temperature sensor port adapted to receive patient temperature readings from a patient temperature sensor;
• a display;
• a memory;
• and
• a controller adapted to perform the following:
• to control the heat exchanger in order to control the patient's temperature, to display on the display a graph comparing a current parameter of the current thermal therapy session to past statistical data from previous thermal therapy sessions implemented using the thermal control unit, to record in the memory patient temperature readings with respect to time during a current thermal therapy session, to record in the memory a first number equal to a total amount of time the patient temperature is within a threshold range of a patient target temperature during a maintenance phase of the current thermal therapy session, to display on the display the recorded patient temperature readings with respect to time after the current thermal therapy session is completed, to display on the display the first number after the current thermal therapy session is completed, to determine a second number equal to an amount of overshoot of the recorded patient temperature readings with respect to the patient target temperature, and to display the second number after the current thermal therapy session is completed.
