    • PROBLEM TO BE SOLVED: To achieve a medical treatment which has a new function and is excellent in lubricity, lubricating durability, and a water-holding property without spoiling the flexibility of a metal coil even when performing coating a metal base material with a thin film, since securing of the lubricating durability is difficult although various methods for making the film thickness of a coating resin layer as thin as possible are so far examined in manufacturing of a guide wire for PTCA, etc.SOLUTION: A hydrophilic polymer is chemically fixed by coating a surface of the base material, which composes a medical instrument, with a specific polyurethane urea resin, and thereby attaining the object such as the outstanding lubricity when wetted.
    • 要解决的问题:为了实现具有新功能,具有优异的润滑性,润滑耐久性和保水性的医疗,即使在用薄膜进行金属基材涂覆时也不会破坏金属线圈的柔性 由于尽管在制造PTCA导丝等方面尽可能多地制作涂膜树脂层的薄膜的方法尽可能薄,但确保润滑耐久性是困难的。解决方案:亲水性聚合物通过以下方式化学固定: 将构成医疗器械的基材的表面与特定的聚氨酯脲树脂进行涂布,从而达到润湿时优异的润滑性的目的。
