Изобретение касается мембран из полого волокна на основе полисульфона. Мембрана из полого волокна имеет внутренний плотный покрывающий слой, образованный из полисульфона и меньшего количества поливинилпирролидона, причем содержание поливинилпирролидона в плотном покрывающем слое выше, чем во внешнем поверхностном слое. Данная мембрана обладает прекрасной биосовместимостью и антитромбогенными свойствами и поэтому может использоваться для обработки жидкостей организма, такой, как гемодиализ, гемофильтрация и гемоконцентрация, без забивания их тромбами.The invention relates to polysulfone-based hollow fiber membranes. The hollow fiber membrane has an inner dense coating layer formed of polysulfone and less polyvinylpyrrolidone, wherein the content of polyvinylpyrrolidone in the dense coating layer is higher than in the outer surface layer. This membrane has excellent biocompatibility and antithrombogenic properties and therefore can be used to treat body fluids, such as hemodialysis, hemofiltration and hemoconcentration, without clogging them with blood clots.
