Artificial lung and heart-lung circuit device

The present invention is an invention which aims to provide a technique for designing an artificial lung can exhibit overall excellent performance can uniformly examined the performance of each element of the artificial pulmonary evaluation, for gas exchange an artificial lung equipped with a heat exchanger unit having elements for gas exchanger unit and the heat exchanger having an external perfusion type hollow fiber membrane bundle, the heat exchange coefficient of performance of the artificial lung, the blood priming volume and the artificial lung oxygenator measuring the blood side pressure loss, Fp3 = calculates the oxygenator heat exchanger performance coefficient / (blood side pressure loss of the blood-filled volume × artificial lung artificial lung), oxygenator value of Fp3 is 0.15 or more I will provide a.
