FIELD: medicine.
SUBSTANCE: invention relates to medical equipment. Hollow fibre membrane contains a hydrophobic polymer, a hydrophilic polymer, and a fat-soluble vitamin. Amount of fat-soluble vitamin on the inner surface of the hollow fibre membrane is 10 mg/m2 or more and 300 mg/m2 or less. Oxygen permeability of the tank is 1.8 × 10-10 cm3 × cm/(cm2 × s× cm hg) or less. Container material is selected from the group consisting of vinyl chloride resin, polycarbonate resin, abs resin, acrylic resin, polyester resin, polyolefin resin, polysulfone resin, polyphenylene oxide resin, and polyacetal resin.
EFFECT: hollow fiber membrane blood purifier is disclosed in which the container is filled with a hollow fiber membrane.
