Artificial lung and cardiopulmonary circuit device

摘要

The present invention is an invention that aims to provide a technique for designing and evaluating an artificial lung that can comprehensively examine the performance of each element of the oxygenator and that can exhibit comprehensively excellent performance. An oxygenator comprising a gas exchanger part having an external perfusion-type hollow fiber membrane bundle and a heat exchanger part having a heat exchange element, which has gas exchange performance, heat exchange performance coefficient, blood filling amount and blood side pressure loss. Measure and calculate Fp = (Gas exchange performance × Heat exchange performance coefficient) / (Blood filling amount × Blood side pressure loss) to provide an artificial lung whose Fp value is 1.5-2.5.
