Abstract
The present invention is directed to an oxygenator using a hydrophobic porous hollow fiber membrane possessing an inside diameter in the range of 150 to 300 microns, a wall thickness in the range of 10 to 150 microns, and a substantially circular cross section, which porous hollow fiber membrane possesses an average crimp amplitude in the range of 35 to 120% of the outside diameter, a maximum crimp amplitude/crimp half cycle period at maximum crimp amplitude ratio in the range of 0.01 to 0.1, and a crimp ratio in the range of 1.0 to 3.0%, and a method for the production thereof.
