We have developed oxygenetor for pumpless Extracorporeal Membrane Oxygenation (ECMO) system. It is required low pressure drop, blood priming volume and gas exchange performance in pumpless ECMO. In this study, we performed analysis of oxygenetor using computational fluid dynamics (CFD) for increase in performance. In addition, oxygenetor was fabricated based on the result of CFD. In the CFD, it was calculated uniformity of flow velocity in fiber bundle, low blood pressure and low riming volume. O_2 was fully added to oxygenator, on the other hand, CO_2 removal was difficult in in vitro evaluation. The value of pressure drop was not constant was by nonuniformly of flow velocity. In conclusion, this result indicates that uniformity of flow velocity was depended on gas exchange performance and pressure drop.
