Abstract
A blood processing apparatus includes an optional heat exchanger and a gas exchanger disposed within a housing. In some instances, the gas exchanger can include a screen filter spirally wound into the gas exchanger such that blood passing through the gas exchanger passes through the screen filter and is filtered by the spirally wound screen filter a plurality of times.
Claims18
A blood processing apparatus, comprising:
- a hollow core in fluid communication with a blood inlet;
- and
- a gas exchanger disposed about the hollow core;
- wherein the gas exchanger includes a screen filter wound in a continuous series of loops around the hollow core, and a plurality of hollow fibers secured to the screen filter, wherein at least some of the hollow fibers have an outer diameter ranging from about 100 microns to about 1000 microns.
