摘要：
The device of the present invention includes a dual chamber gas exchanger that is configured for increased flexibility and scalability for many clinical applications. The dual chamber oxygenator can be configured and used in various applications, such as in a heart-lung machine for cardiopulmonary support during cardiothoracic surgery, in an extracorporeal membrane oxygenation (ECMO) circuitry, as a respiratory assist device for patients with lung failure, and the like. The dual chamber gas exchanger features two sweep gas flow paths and two gas exchange membrane bundles enclosed in a housing structure with various blood flow distribution and gas distribution mechanisms. The gas exchanger includes an outer housing, an intermediate housing, two gas exchange fiber bundles, a blood inlet, a blood outlet, two gas inlets, two gas outlets, two gas distribution chambers and an optional heat exchanger.
