Abstract
The present disclosure describes a blood oxygenator that includes a checkerboard layout of fluid (e.g., blood) and gas (e.g., oxygen) channels. When viewed as a cross-section through each of the channels of the oxygenator, the checkerboard configuration includes alternating gas and fluid channels in both the x-axis (e.g., in-plane) and in the y-axis (e.g., out-of-plane) directions. The oxygenator described herein reduces manufacturing complexity by using first, second, and third polymer layers that include asymmetrical channel designs. The channel designs include 'open' gas channels, which are exposed to the ambient atmosphere. The oxygenator is placed within a pressure vessel to drive gas into each of the open gas channels, which in some implementations, negates the need for a gas manifold.
