Abstract:
A hollow fiber blood oxygenator is provided having a plurality of enclosed, coaxial heat exchanger coils, having a common header to insure uniform temperature in the coils. An enclosed fiber bundle is concentrically positioned inside the heat exchanger coils to define a flow path around the coils and through the fiber bundle. The heat exchanger coils and the outside of the fiber bundle are tapered to provide a close fit. Gas manifolds direct gas flow to and from the hollow fibers.
