ABSTRACT OF THE DISCLOSURE The present invention discloses a blood cleaning hollow fiber membrane characterized by comprising a hydrophobic porous hollow fiber membrane and having a hydrophilic thin layer formed at least on the inner surface of said hollow fiber membrane by the grafting of a hydrophilic compound through the agency of a gamma ray. Also disclosed is a method for the cleaning of freeze preserved blood in which either first or second liquid passing spaces of a plurality of blood cleaning apparatuses are connected in series, each such apparatus incorporating therein a multiplicity of porous hollow fiber membranes. As a result, continuous blood flow paths are formed, and these paths are disposed substantially linearly and effect the required cleaning of blood by passing the blood to be cleaned through the continuous blood flow paths. Different or similar cleaning liquids are fed to the plurality of second liquid passing spaces or first liquid passing spaces which are independent of each other.
