ABSTRACT:
An oxygenator for blood which comprises means for removably holding a membrane oxygenator unit, means for conveying blood to a patient through the oxygenator unit in a first flow path and back to the patient, and means for supplying oxygen gas through the oxygenator unit in a second flow path separated from the first flow path in the unit by a semi-permeable membrane. The oxygenator unit holding means carries a plate which has an oxygen inlet manifold port positioned to communicate with a mounted oxygenated unit, to provide a sealed oxygen flow path through the plate into the oxygenator unit and to provide for dispersal of effluent oxygen in a plurality of directions, thereby preventing the accidental obstruction of the oxygen outlet of the unit.
