Abstract
Waterless temperature control of blood in a blood oxygenator is achieved by providing a non-disposable heater/cooler with a temperature-controlled surface that can be intimately mated with a heat-conducting surface of a disposable blood heat exchanger associated with the oxygenator. Blood flows in a shallow path past the heat-conducting surface so that substantially all of the blood will assume the temperature of the heat-conducting surface as it flows past that surface.
