具有亲水涂层的改进的医疗装置
摘要：
公开了一种医疗装置，其包含基底和布置在所述的基底上的亲水表面涂层。该基底在它的涂覆有所述的亲水表面涂层的表面上具有表面纹理，该表面纹理具有至少3μm的表面轮廓算术平均偏差(Ra)和/或至少18μm的轮廓剖面高度差(Rdc(1-99％))。已经发现提高基底的表面粗糙度提供了例如在亲水涂层保水性方面的明显改进。
摘要（英）：

A medical device is disclosed, comprising a substrate and a hydrophilic surface coating arranged on said substrate. The substrate has, on its surface coated with said hydrophilic surface coating, a surface texture with an arithmetical mean deviation of the surface profile (Ra) of at least 3 [mu]m and/or a profile section height difference (Rdc (1-99%)) of at least 18 [mu]m. It has surprisingly been found that the increased surface roughness of the substrate provides significant improvements in e. water retention for the hydrophilic coating.
