Abstract
A gas exchange apparatus for use as a artificial lung incorporates a hollow fiber module for bundling a plurality of thin-walled hollow silicone fibers. The fibers are wound in the form of a twilled pattern so as to form an internal perfusion passage and an external perfusion passage. A housing encloses the hollow fiber module. The housing incorporates a first inlet and outlet formed on the housing for communication of gas or liquid with the internal perfusion passage, and a second inlet and outlet formed for communication of gas or liquid with the external perfusion passage.
