Abstract

Dans l'hémodialyseur selon l'invention, l'augmentation du contact est obtenue en augmentant en même temps le trajet d'écoulement et la vitesse du sang pour éviter l'accumulation de fibrine. L'hémodialyseur comporte une boîte 11 contenant deux groupes indépendants 15 et 17 de tubes 13 en membrane semi-perméable, les deux groupes étant séparés par une cloison 47 arrivant à peu de distance de la paroi latérale 45 de la boîte afin que le sang arrivant par l'entrée 31 soit obligé de passer d'abord entre les tubes 13 du groupe 15 et ensuite entre les tubes 13 du groupe 17 vers une sortie correspondant à l'entrée 31.In the hemodialyzer according to the invention, the increase in contact is obtained by simultaneously increasing the flow path and the speed of the blood to prevent the accumulation of fibrin. The hemodialyzer comprises a box 11 containing two independent groups 15 and 17 of tubes 13 made of semi-permeable membrane, the two groups being separated by a partition 47 arriving at a short distance from the side wall 45 of the box so that the blood arriving through the inlet 31 is obliged to pass first between the tubes 13 of the group 15 and then between the tubes 13 of the group 17 to an outlet corresponding to the inlet 31.
