摘要： An artificial lung comprises a venous blood reservoir to receive and store venous blood. A heat exchanger communicating with the venous blood reservoir receives the venous blood so the blood temperature is regulated by heat exchange through a wall between flowing water and the venous blood. A blood oxygenator concentrically disposed within a hollow space of said heat exchanger comprises a cylindrical body defining a cylindrical space and at least one gas permeable membrane separating said cylindrical space into a first space and a second space. The first space receives the venous blood from the heat exchanger and the second space communicates with an oxygenating gas feed line so that the blood is oxygenated through the gas permeable membrane.

摘要： A blood oxygenator includes an elongated hollow housing having an elongated chamber therein, an elongated fiber assembly disposed within the chamber along an axis thereof and including a bundle of hollow fibers of a microporous membrane. The opposite ends of the fiber bundle are sealingly secured to the inner peripheral surface of the housing by a potting material. Gas inlet and outlet members are connected respectively to the opposite ends of the housing and communicate respectively with the opposite ends of the hollow fibers. Blood inlet and outlet are formed on the housing and communicate with the chamber intermediate the opposite ends of the hollow fibers. The fiber assembly includes a plurality of layers of spirally-wound fiber bundles arranged one upon another. Each turn of one of each adjacent spirally-wound bundles is disposed in a plane intersecting the plane in which each turn of the other fiber bundle is disposed. The outer periphery of the outermost layer of the spirally-wound bundle is held in contact with the inner peripheral surface of the housing.

摘要： An integrated heart-lung machine, which includes a blood pump having a casing of a cup-like shape interiorly defining a pump chamber at an intermediate portion thereof for pumping in and out blood from a blood inlet to a guide flange formed at opposite ends of the casing; a rotor having a rotary member securely fixed to the fore end thereof within the pump chamber and journalled in the guide flange; an artificial lung of a doughnut-like or cylindrical shape connected contiguously to a blood flow passage in the guide flange and concentrically with the rotor; a stator detachably fitted in an intermediate portion between the rotor and the artificial lung; and a pedestal base located at one side of the artificial lung and provided with a blood outlet in communication with the artificial lung. Accordingly, influent blood to the pump chamber is sent into the artificial lung through the blood passage by the pumping action of the rotor, and is refreshed by contact with air or oxygen in the lung, which is maintained in a heated state by the stator, and returned to the patient's body through the blood outlet. This arrangement permits minimizing of the length of the blood circulating passages to and through the machine and permits shortening and minimizing of the blood passages interconnecting the blood pump, artificial lung and blood filter, while preventing blood contamination and leaks as well as blood cell destruction. Easy installation and handling is also permitted in a sanitary region on a bed or on an operating table.
