Membrane unit and device for cleansing blood
First Claim
1. A membrane unit for simultaneously removing toxic metabolites and metabolites normally present in urine from blood, comprising at least one cavity through which the contaminated blood passes, said cavity being defined by a first wall comprised of a permselective membrane having a pore size adapted to selectively remove from the blood metabolites normally present in urine, including water, electrolytes, urea and ammonia, and a second wall spaced from said first wall and comprising at least one adsorbant for removing toxic metabolites from the blood, whereby the blood simultaneously directly contacts both said first and second walls in said cavity.
