Abstract
A woven pattern consists of curved tubes with periodically varying curvature, such as serpentine tubes, and it gives two primary benefits; first gas transfer performance is augmented due to secondary flow induced at the curved portion of the tubing and second, the packing density of tubes becomes larger. These features make it possible to design a compact membrane oxygenator by utilizing the curved tubes wound in woven patterns. In this study, gas transfer performance in blood was investigated by ex vivo dog experiments for prototypes having curved tubes wound in woven patterns. All prototypes were built with microporous teflon tubing (Gore Tex). The augmentation effect of gas transfer performance similar to that of helically coiled tubes was obtained for all of the prototypes built, but the flow resistance in the blood path turned out to be relatively lower than that of helical coils. The packing density of woven tubes went up to 1. 4 times as high as that of helically coiled tube of a similar diameter. These results offer the fundamental design characteristics with which the optimal woven structure used for practical applications can be determined.
