film oxygenator a device, encased in a container of oxygen, that makes possible reduction of a thin film of blood to facilitate the exchange of gases.
pump oxygenator heart-lung machine.
rotating disk oxygenator a type of film oxygenator in which a series of parallel disks rotate through an extracorporeal pool of venous blood in a container of oxygen; gaseous exchange occurs between the thin film of blood on the exposed surface of the disks and the oxygen in the container.
screen oxygenator a type of film oxygenator in which the venous blood is passed over a series of screens in a container of oxygen, gaseous exchange taking place in the thin film of blood produced on the screens.
