    摘要： A combined heat exchanger/blood reservoir, comprises a housing (42) topped by a lid (44) together defining a reservoir chamber (52) within, a venous blood inlet (66) in the lid and a heat exchanger within the chamber including a plurality of heat exchange elements (88). The heat exchange chamber (86) is defined by guides (82, 84) closely surrounding the heat exchange elements (88) and extending downward from a location at an upper portion of the reservoir chamber, the heat exchange chamber (86) having an upper inlet (80) open to the venous blood inlet and a lower outlet (92) open to the reservoir chamber so that blood from the venous blood inlet must flow through the heat exchange chamber before reaching the reservoir chamber. A blood outlet (118) is provided in a lower portion of the reservoir chamber.

    摘要： The obstruction of a curved blood manifold window (27) in a blood oxygenator (10) by oxygenation fibers (46) which lie along a chord (58) of a curved window (27) when wound upon the oxygenator core (44) is avoided by recessing the manifold wall portions (38) most closely adjacent the window (27) sufficiently so that the fibers (46) lying on that chord (58) remain sufficiently spaced from those closest wall portions (38) to allow blood flow between those wall portions (38) and the closest fibers (46).

    摘要： A device (1) for oxygenating blood in an extracorporeal circuit includes a first structure (2) suitable to delimit a portion of space (6)-containing capillaries made of microporous membrane. The capillaries convey oxygen and are wet externally by blood flowing through a portion of space (6) between an intake connector (8), which is connected to a venous line of the extracorporeal circuit, and a delivery connector (10). The device (1) includes a second structure (3) monolithically connected and contiguous to the first structure (2). The second structure (3) is suitable to contain blood filtration means (28) that divide the portion of space delimited thereby into a blood distribution chamber (11), provided with an air vent (15) and connected to the delivery connector (10) of the first structure (2), and a blood collection chamber (13) provided with a delivery connector (10) connected to the arterial line of the extracorporeal circuit.

    摘要： A low prime membrane oxygenator (150) and an integrated heat exchanger/reservoir (24, 40) for use alone or in combination in an extracorporeal blood circuit. The oxygenator has a simple, five-part construction including a housing (152) defining an annular oxygenation chamber (168) within which a plurality of hollow fibers (160) are arranged in an annular bundle with flow spaces therebetween. A blood inlet port and manifold deliver blood through a plurality of evenly circumferentially spaced inlet apertures to the oxygenation chamber, and blood flows generally axially through the elongated annular chamber to a plurality of evenly circumferentially spaced outlet apertures. Specific geometric ratios, a particular hollow fiber architecture, and the absence of a heat exchange function, all combine to reduce the prime volume required by the oxygenator. The reservoir (24, 40) includes heat exchange coils (88) in an annular chamber (86) providing efficient heat transfer with low prime volume.
