  • Rigid shell expansible blood reservoir, heater and hollow fiber membrane oxygenator assembly
    Patent number: 4424190
    Abstract: A closed, air-free blood oxygenator assembly having integrated into one self-supporting unit a rigid-shell blood reservoir having an easily visible, concavity which is closed by an attached expansible, flexible membrane which overlies the concavity and forms a variable volume liquid and air-tight blood reservoir, and an attached blood heater, and a hollow fiber membrane oxygenator. The assembly stores, heats, oxygenates and purifies blood by passing oxygen through the lumens of a mat of small diameter gas-permeable hollow fibers supported on a cylindrical core as blood flows over the outside surfaces of the fibers in a small, easy to use, safe, integrated unit which avoids blood contact with ambient air as blood circulates through the assembly during surgery.
