An integral blood oxygenator and blood temperature controller combination concurrently provides blood oxygenation at a precise blood-gas temperature required by a patient. The integral combination operationally insures that the extra-corporeal circulating blood is equilibrated with oxygen gas at a patient's required blood temperature. Multiple, small diameter aperture, equal length oxygen exchange tubes are adjacently spaced in a patterned, parallel array and secured at the pairs of tube terminus in an opposed pair of tube header plates, forming a blood-gas-energy exchange tube array. The two-phase blood-oxygen-gas mixture flows upward inside each of the single oxygen exchange tubes, absorbing oxygen and evolving carbon dioxide gas. Precisely temperature controlled water circulates through the gas exchange tube array around the exterior of the oxygen exchange tubes, providing precise blood temperature control during oxygenation process. By equilibrating oxygen consumption and carbon dioxide evolution at a precise blood temperature, undesired gas bubble evolution at higher random blood temperature excursions are minimized, lowering the potentiality of gas bubble evolution and gas embolism. |
