    摘要： A copolymer comprising a monomer of formula (1) below and a monomer having a basic functional group copolymerizable with the monomer as monomer components, wherein molar ratio of the monomer of formula (1) to the monomer having a basic functional group is 85/15 to 99.9/0.1 and wherein the copolymer has a number based mean molecular weight of 5,000 to 500,000. The copolymer is excellent in antithrombotic activity and further in biocompatibility and can be used as a medial material having high hydrophilicity. It also can serve as an antithrombotic surface treating agent. (wherein R1 is an alkylene group having 1 to 4 carbon atoms, R2 is an alkyl group having 1 to 4 carbon atoms, and R3 represents hydrogen or a methyl group).

    摘要： A remover unit for use in a circuit for removing at least leukocyte from blood or blood preparations, which comprises a remover includes a housing having a blood inlet, a blood outlet, and a filter interposed between the blood inlet and the blood outlet, and at least one air vent having a cap for opening and closing the air vent to ambient atmosphere. With the air vents having such a cap, the removal of air in the course of priming the remover, the operation of starting or stopping filtration, the recovery of residual liquids in the remover and the removal of air from the recovery bag can be facilitated. The filter includes a three-dimensionally reticular, porous member with continuous open pores having a most frequent pore diameter to a number average pore diameter ranging from 1.5 to 2.5.
