Document Type and Number:
WIPO Patent Application WO/2023/080237
Kind Code:
A1
Abstract:
This hollow fiber membrane blood purifier includes hollow fiber membranes and a container in which the hollow fiber membranes are packed, wherein the hollow fiber membranes in the hollow fiber membrane blood purifier contain a fat-soluble substance, the proportion of flat fibers among all hollow fibers included in the hollow fiber membrane blood purifier is 5% or less, the flat fibers being such that the flatness calculated by formula (1): "short diameter of the outside diameter of the hollow fiber cross-section/long diameter of the outside diameter of the hollow fiber cross-section" is 0.5 or less, and the amount of the fat-soluble substance immobilized on the hollow fiber membrane being 1-500 mg/m2.
