曲り管膜型人工肺の試作:物質伝達促進を利用したコンパクト化

抄録

One of the attractive ways to design compact oxygenators with high gas transfer performance, is to weave tubings tightly. This gives basically two advantages: the augmentation of gas transfer due to curved tube and larger packing density of tubes. In this study gas transfer performances in water and blood were investigated experimentally for prototype units having four single tubes wound in two kinds of weaving patterns. The augmentation effects similar to that of helical coils were obtained for both units, however, the flow resistance in the blood path turned out to be half that of helical coils.
