  • Integrated membrane oxygenator, heat exchanger and reservoir
    Patent number: 4876066
    Abstract: A membrane oxygenator includes an upper nested arrangement of a hard shell venous reservoir, a bowl-like defoamer within the reservoir and a heat exchanger coil vertically supported within the defoamer, and includes a membrane oxygenator unit mounted on the bottom of the upper arrangement. The oxygenator unit includes an inlet chamber with a tangential inlet providing swirling blood flow to dislodge air bubbles and centrifuge air to an upper center region of an inlet chamber where gas is exhausted through a vent. A bottom blood outlet chamber of the blood oxygenator unit has a relatively thin vertical cross-sectional area such that priming flow velocity therein discharges all air from the outlet chamber.
    Type: Grant
    Filed: July 14, 1987
    Date of Patent: October 24, 1989
    Assignee: Baxter International Inc.
    Inventors: Richard L. Bringham, Lucas S. Gordon, Karl E. Mosch
