OXYGENATOR WITHOUT INTEGRATED HEAT EXCHANGER, WITH COMMON HEAT EXCHANGER FOR PATIENT'S SYSTEMIC BLOOD CIRCULATION AND CARDIOPLEGIA DELIVERY SYSTEM AND METHODS THEREOF

摘要

A medical device for oxygenation, removal of carbon dioxide, temperature exchange in the patient's blood and, in addition, for delivering the cold/warm blood/crystalloid cardioplegia to the cardiac muscle in an extracorporeal circuit during heart surgery. A single heat exchanger is used either for patient's systemic blood circulation or cardioplegia delivery to the heart, whenever it is needed.
