    • A hollow fiber membrane type blood purifier packed with hollow fiber membranes comprising a polysulfone resin and polyvinylpyrrolidone. Even when sterilized by irradiation with a radiation, the hollow fiber membrane type blood purifier is less apt to suffer polyvinylpyrrolidone dissolution and can be inhibited from decreasing in blood compatibility. The purifier is of the type called semidry, and is lightweight and has excellent handleability. The hollow fiber membrane type blood purifier comprises a bundle of hollow fiber membranes comprising a polysulfone resin and polyvinylpyrrolidone, a container packed therewith, and a potting agent disposed between each bundle end and the container to hold the bundle and thereby form a hollow-fiber-membrane inside chamber and a hollow-fiber-membrane outside chamber. The purifier has fluid ports connected to the hollow-fiber-membrane inside chamber and a fluid port connected to the hollow-fiber-membrane outside chamber. The hollow fiber membrane type blood purifier is characterized in that the hollow fiber membranes have, adherent thereto, a radical trapping agent in an amount of 80-300% based on the dry weight of the hollow fiber membranes, have a water content of 40-100%, excluding 100%, and have been sterilized with a radiation.
    • 一种中空纤维膜型血液净化器,其中填充有包含聚砜树脂和聚乙烯吡咯烷酮的中空纤维膜。 即使通过放射线照射进行杀菌,中空纤维膜型血液净化器也不易受到聚乙烯吡咯烷酮的溶解,可以抑制血液相容性的降低。 净化器属于半干型,重量轻,操作性好。 中空纤维膜型血液净化器包括一束由聚砜树脂和聚乙烯吡咯烷酮组成的中空纤维膜,一个装在其中的容器,以及一个灌封剂,灌封剂位于每一个束端和容器之间以保持该束并由此形成中空纤维膜型血液净化器, 室内的膜和室外的中空纤维膜。 净化器具有连接到腔室内的中空纤维膜的流体端口和连接到腔室外的中空纤维膜的流体端口。 中空纤维膜型血液净化器的特征在于,中空纤维膜附着有基于中空纤维膜干重80-300%的自由基捕获剂,其含水量为40-90% 100%,不包括100%,并已通过辐射灭菌。
