Abstract
A blood purification means whereby blood of a patient to be treated is led around an external circuit connecting to the patient's blood stream and is brought into direct or indirect contact with a fumarate solution, and is further brought into direct or indirect contact with an enzymic preparation, which is suitably an aspartase preparation, which catalyzes a reaction of L-aspartic acid formation from fumaric acid and ammonia. The purification means may further include a preliminary stage or stages whereat an unrequired substance in a patient's blood is decomposed to a non toxic substance and ammonia subsequently convertable to aspartic acid, and may also include a low molecular sieve means preventing re-entry of aspartic acid produced into the patient's blood stream.
