在膜式氧合器水气传递实验装置上分别对二种不同的交叉流微孔聚丙烯中空纤维膜式氧合器进行了水气传递实验，测得了氧合器的结构因子α、β，并用Ｍｏｃｋｒｏｓ和Ｌｅｏｎａｒｄ对Ｏ２传递建立的半经验数学模型拟合了血气传递实验中氧气在血中的传递速率。结果表明，理论计算与实验数据十分吻合，偏差小于１０％。讨论了α、β与膜式氧合器的传递效果的关系。 Two different cross-flow microporous polypropylene hollow fiber membrane oxygenators were tested for moisture transfer in membrane oxygenator water vapor transfer experiment device. The structure factors α, β, The half-empirical mathematical model established by Mockros and Leonard for O2 transport was used to fit the oxygen transfer rate in the blood gas transfer experiment. The results show that the theoretical calculation is very consistent with the experimental data, the deviation is less than 10%. The relationship between α, β and membrane oxygenator delivery is discussed.
