Patent ID: 8202428

Claim:
A method for filling a hollow fiber dialyser for hemodialysis, comprising the steps of: using a cylindrical filter housing with a bundle of hollow fibers arranged therein, wherein a volume of air is present in the housing in a space surrounding the hollow fibers; guiding a first fluid volume flow from a top portion to a bottom portion of the cylindrical filter housing; and displacing the volume of air present at the beginning of the guiding step in the space surrounding the hollow fibers with the first fluid volume such that the space surrounding the hollow fibers is air-free, wherein a fiber allocation in the cylindrical filter housing is between 60.5% and 70%, and wherein the hollow fibers of the bundle each have a curling according to the following: d 5 < a < λ 5 λ representing a wavelength of each of the curled hollow fibers, d representing an outer diameter of each of the curled hollow fibers, and a representing an amplitude of the periodic texture, wherein 4 mm<λ<12 mm.
