HOLLOW FIBER MEMBRANE BLOOD PURIFICATION DEVICE Russian patent published in 2018 - IPC A61M1/18 A61L31/00 A61K31/355 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment field. Device includes membranes in the form of hollow fibers, loaded into a reservoir. Membranes contain a hydrophobic polymer, a hydrophilic polymer, and a fat-soluble vitamin. When the bundle of membranes in the form of hollow fibers is divided into five sections in the longitudinal direction and divided sections, located in the most terminal areas, are defined as the end parts of the body, the amount of fat-soluble vitamin, which is present in at least one of the end parts of the body, is the largest among the amounts of a fat soluble vitamin, which are present, respectively, in any of the divided sections. Amount of fat-soluble vitamin per unit area of the inner surface of the membrane in the form of hollow fibers, at least one end portion of the body is 20 mg/m² or more and 300 mg/m² or less.

EFFECT: technical result consists in improving the antioxidant characteristics, water conductivity and compatibility with blood.
