Provided are surface treatment agents that enable surfaces with a chemically fixed lubricant to be produced instead of a resin coating which has drawbacks, such as that lubricity is reduced due to separation, peeling or the like of the coating during the movement within a vessel or tube; and medical devices, such as catheters, having a surface at least partially treated with such a surface treatment agent. The present invention relates to a surface treatment agent for medical devices which contains a copolymer of a hydrophilic functional group-containing monomer and an epoxy group-containing monomer.
本发明提供的表面处理剂可代替具有缺点(如涂层在容器或管道内移动时因分离、剥落或类似情况而导致润滑性降低)的树脂涂层,生产出具有化学固定润滑剂的表面;本发明还提供了表面至少部分经过这种表面处理剂处理的医疗器械,如导管。本发明涉及一种用于医疗器械的表面处理剂,它包含一种含亲水官能团单体和一种含环氧官能团单体的共聚物。
