Abstract:
A blood heat exchange system for a blood oxygenator, comprising;a) a non-disposable heater-cooler unit having a temperature-controlled external surface;b) a disposable oxygenator unit releasably matable with said heater/cooler unit, said oxygenator unit including:i) an oxygenation section arranged to oxygenate blood flowing therethrough; andc) said path being defined at least in part by a heat-conducting external surface of said oxygenator unit, said heat conducting surface being arranged to lie in intimate contact with said temperature-controlled surface when said heater/cooler unit and said oxygenator unit are mated;d) said path along said heat-conducting surface being sufficiently narrow so that the blood passing through said path will substantially uniformly assume the temperature of said heat-conducting surface as it passes said heat-conducting surface.
