摘　　要：本文对自制的血管内置入型人工肺 (IVOX)的性能以生理盐水为介质进行了invitro测试 ,并用Vaslef等人的半经验理论模型对实验测试结果进行了计算 ;结果表明自制的IVOX具有一定的氧合和排二氧化碳功能 ,Vaslef等人的半经验模型可方便有效的表达IVOX的传质效果。In vitro tests with physiological saline were carried out for evaluating self-made IVOX. Its data were treated with Vaslef′s semi-empirical theoretical model. The results show that self-made IVOX had certain oxygenation and CO 2 removal capacity, and Vaslef′s semi-empirical theoretical model was effective and reliable for predicting gas transfer in IVOX.
