Abstract
A device and method for oxygenating blood is disclosed herein. The device includes a plurality of passive mixing elements that causes a fluid to mix as it flows through the device. The passive mixing elements continually expose new red blood cells to the portion of the flow channel where oxygenation can occur. Accordingly, in some implementations, the device and method uses less blood to prime the device and allows for the oxygenation of blood with a substantial shorter flow channel when compared to conventional oxygenation methods and devices.
