BLOOD OXYGENATOR Russian patent published in 1995 - IPC

FIELD: medical engineering. SUBSTANCE: blood oxygenator includes main mass-exchange chamber, perfluorodecalin outlet which successively communicates via pump with perfluorodecalin oxygenator and chamber to liberate excess gas from perfluorodecalin. Outlet of this chamber communicates with perfluorodecalin inlet of main mass-exchange chamber having blood inlet and outlet in upper portion of side wall, which is in communication with blood transfer line incorporating pump. Main chamber is cylindrical hermetically sealed reservoir made from transparent plastic polymer and provided with electromagnetic agitator, which is metallic rotator, and externally positioned electromagnet. Perfluorodecalin inlet connection communicates with chamber central portion via horizontal passage. Outlet connection is disposed in lower portion of chamber's side wall.
