    • Provided herein are hemo-compatible, anti- and non-thrombogenic, heparin-based bioactive coatings for a surface to be contacted with blood, such as a surface of an oxygenator device (e.g., a Hollow Fiber Membrane (HFM) surface) or an artificial lung, which coatings include a quaternary ammonium salt and heparin complex (QUAT). According to example embodiments, the surface is treated with polyvinylpyrrolidone (PVP), followed by a coating layer of said quaternary ammonium salts and heparin complex (QUAT) to form a PVP-QUAT coating. According to other example embodiments, anionic functional groups are created on the one or more surfaces of the HFM by modifying the surface of the HFM using ionic complexes dissolved in a solvent mixture that includes major quantity of alcohol along with a minor quantity of organic dissolving agents. Also provided are methods of making the provided coatings, methods of coating a surface, oxygenator devices and artificial lungs that have been coated, and kits that include such coatings.
    • 本文提供了与血液接触的表面(例如氧合器装置(例如中空纤维膜(HFM)表面))的表面的血红素相容性,抗和非血栓形成的基于肝素的生物活性涂层,或 人造肺,其涂层包括季铵盐和肝素复合物(QUAT)。 根据示例性实施方案,用聚乙烯吡咯烷酮(PVP)处理表面,随后用所述季铵盐和肝素复合物(QUAT)的涂层处理以形成PVP-QUAT涂层。 根据其他示例性实施方案,通过使用溶解在溶剂混合物中的离子络合物来改变HFM的表面而在HFM的一个或多个表面上产生阴离子官能团,所述溶剂混合物包括主要量的醇以及少量的有机溶解剂 。 还提供了制备所提供的涂层的方法,涂覆表面的方法,已经被涂覆的氧合器装置和人造肺以及包括这种涂层的试剂盒。
