A membrane-type artificial lung adapted to perform exchange of gases between blood and a gas through a membrane by passing blood over one side of the membrane and oxygen or an oxygen-containing gas over the other side, said membrane being a hollow fiber membrane which is composed mainly of a polyolefin, has an inside diameter of 10 to 500 micrometers, a thickness of 5 to 100 micrometers, a porosity of 7 to 50% and an oxygen flux, Q(O.sub.2), of at least 1.times.10.sup.-6 [cm.sup.3 (STP)/(cm.sup.2.sec.cmHg)] and is substantially impermeable to ethanol.

Artificial lung and method of using it

Disclosed is a fluid treating apparatus of hollow fiber type. The apparatus can prevent channeling or stagnation of the fluid which flows inside it by specifying the densities of the hollow fibers and the warps forming a hollow fiber sheet and the laminating conditions for laminating the hollow fiber sheets to form a laminate which is to be housed in a housing.
