Abstract:
1. An apparatus for de-aering, oxygenating and controlling a temperature of blood in an extracorporeal blood circuit, the apparatus comprising: a housing generally defining a first chamber and a second chamber, the first chamber being fluidly open to the second chamber; a blood inlet fluidly open to the first chamber and arranged relative to a side wall of the first chamber to direct incoming blood tangentially into the first chamber; a manifold body disposed within the second chamber, the manifold body including a core forming a head and a plurality of vanes projecting from an outer surface of the core to define a plurality of channels, wherein the manifold body is arranged such that the head is aligned with the first chamber; a heat exchanger disposed within the second chamber and including a plurality of heat transfer elements arranged around the manifold body, wherein the channels are open to the heat exchanger; an oxygenator disposed within the second chamber and including a plurality of gas exchange elements arranged around the heat exchanger; and a blood outlet fluidly open to the second chamber; wherein the apparatus establishes a blood flow path from the blood inlet to the blood outlet, including 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 second chamber.
