摘要：
An apparatus for de-aering, oxygenating and controlling a temperature of blood in an extracorporeal blood circuit. The apparatus includes a housing, a manifold body, a heat exchanger, and an oxygenator. A blood inlet tangentially directs blood into a first chamber of the housing. The manifold body is disposed in a second chamber, and includes a core and a plurality of vanes that define channels. The heat exchanger is arranged around the manifold body, and the oxygenator around the heat exchanger. The channels are open to the heat exchanger. An established blood flow path includes rotational flow within the first chamber to separate air from the blood, generally longitudinal flow from the first chamber and along the channels, and generally radial flow through the heat exchanger and the oxygenator. With this construction, gross air removal occurs prior to the blood passing through the heat exchanger and oxygenator.
