MODULAR DISPOSABLE BLOOD OXYGENATORS WITH REUSABLE HEAT SOURCE AND OPTIONAL INTEGRATED BLOOD PUMP

摘要

A blood oxygenator/heat exchanger system includes disposable and durable components, the latter being possible of permanent installation to further reduce costs, inconvenience and risks of use. The system may selectively include a blood pump of axial, centrifugal, or ventricular type, along with an integral venous reservoir. By combination, arrangement and cooperation of structural features blood pumping volume is decreased, advantageous blood flow paths are achieved, blood damage is reduced, and durable components are reusable for lowest costs. The oxygenator/heat exchanger nests upon a durable heat source base to be supported thereby, while redundant boundaries are provided between blood and heat transfer media.
