ABSTRACT:
A haemodialyzer apparatus in which there are disposed two different types of membranes, namely, semi-permeable membranes that are substantially incapable of passing therethrough blood plasma proteins and filter membranes that are capable of passing therethrough blood plasma proteins. By the use of the present haemodialyzer apparatus, in addition to urea, creatinine and the like, the relatively high molecular weight substances such as the peptides having a molecular weight of more than 1,000 as well as the plasma proteins with their functions lowered, which relatively high molecular weight substances cannot be removed by any of the conventional haemodialyzers, can be effectively removed, to a desired extent, from the blood, thereby not only purifying or detoxifying the blood or components thereof but also recovering the toxic substances-absoring abilities of the plasma proteins so that the patients suffering from renal and/or liver failure may be remedied more satisfactorily.
