Abstract: Methods and apparatus for an improved Contrast Therapy Device that delivers alternating heated and chilled temperature fluids to a contrast thermal therapy pad. Mitigation processes maintain water temperature in hot water tanks and cold water tanks in order to keep water temperatures in the respective tanks from drifting beyond a desired setpoint range when the system switches a therapy state from a cooling cycle to a heating cycle or from heating cycle to a cooling cycle. Thermal shock is reduced to the fluid tanks. Mitigation techniques include delaying actuation of a return path flow, such as via a diverting solenoid. Mitigating delay can be a static time delay based upon one or both of: a volume of water in a therapy pad and related volume and rate of flow; and meeting a threshold transition temperature for return fluid temperature.

Abstract: A system including apparatus and methods for sanitizing or otherwise reducing biologics present on thermal therapeutic treatment wraps used for treating athletes after workouts or games, physical therapy patients after injury, and hospital patients after surgery is disclosed. The system includes a storage cabinet with an internal conveyor system that exposes each wrap to periodic sanitization or other biologic reduction means, such as ultraviolet light. This prevents growth of bacteria and mold. In some embodiments, warm air is blown into the storage cabinet to assist with drying the wraps.

Abstract: A novel thermoelectric liquid heat exchange device for corrosive or high purity liquids is provided for. The heat exchange device has an array thermoelectric modules, with first and second heat exchanger plates arranged so as to sandwich the thermoelectric modules between the heat exchanger plates. One of the heat exchanger plates has a thermally conductive metal base plate, plastic tubing and a cover plate. The base plate has a flat side contacting the thermoelectric modules, and an opposing side with grooves of a preselected depth. The plastic tubing has a diameter to match the depth of the grooves so that the tubing engages the grooves. The cover plate is fastened to the base plate and over the plastic tubing in the grooves of the base plate to press the tubing into the grooves to improve thermal contact between the plastic tubing and the base plate.
