<p>An oxygenator such as an oxygenator, comprising a cylindrical housing provided with inlet and outlet ports of oxygen, and a bundle of hollow fibers disposed within the housing. The porous hollow fiber made of polyolefin resin, sized at 100 to 300.mu. in inner diameter and 10 to 50.mu. in wall thickness, has an average pore size of 200 to 1,000.ANG. and a porosity of 20 to 80%. The blood is allowed to flow through the hollow fiber and O2-CO2 exchange is effected through the porous wall of the hollow fiber.</p> |
