Abstract: A patient temperature control system (10) uses variable temperature gradient warming/cooling in combination with a warming/cooling device (16), such as a blanket, to increase efficiency in driving a patient's temperature to a desired setpoint, with reduced occurrence of and magnitude of overshoot conditions. In operation, the controller (26) of the system (10) senses the temperature of a patient (12) via a sensor (31), for comparison to a temperature of the circulating water, sensed via sensor (30). If the patient temperature is not sufficiently close to a setpoint temperature, the system (10) is operable to warm/cool the circulating water to a temperature which differs from the patient's temperature by a temperature gradient of 10 ° C., or some other preselected initial temperature gradient.

Abstract: A cold therapy system for appyling a cooling pad to an area of the body of the user. The system comprises a portable insulated cooler with a lid. A reservoir bag of plyable waterproof material is locatable within said cooler and has a closable open top for the introduction of water and ice into the bag. A multispeed pump is located in a housing affixed to the exterior of the cooler. The pump has an inlet operatively connected to an outlet tubing flange affixed to the bag. The pump has an outlet operatively connected to an insulated delivery tube connected to an inlet of the pad. The outlet of the pad is connected by an insulated return tube to an inlet flange of the reservoir bag. A portion of the insulation of one of the delivery and return tubes, is retractable to expose a segment of its respective tube containing a liquid crystal temperature indicator for determining the temperature of the fluid flowing through the system.
