THERMAL CONTROL SYSTEM

Abstract:

A thermal control system for controlling a temperature of a fluid delivered to a patient is provided. The system includes a thermal control unit having a fluid inlet and outlet, a circulation channel, a pump, a heat exchanger, a fluid temperature sensor and a controller that controls the heat exchanger in order to automatically bring a patients temperature to a target temperature. In some embodiments, the control unit includes a user interface adapted to receive a non-temperature patient parameter (e.g. BMI) that the controller uses, along with patient core temperature readings, to control the heat exchanger. The controller may also or alternatively control the heat exchanger based on both core and peripheral patient temperature readings. An auxiliary thermal therapy device for controlling a temperature of the patients blood, air breathed by the patient, and/or other fluid, may also be controlled by the thermal control unit.
