<p>2.1 Metal ions, in particular aluminium ions, are insufficiently excreted by dialysis patients and may be deposited in the bones, which may lead to bone cysts and osteomalacia. The apparatus is intended to permit metal ions, in particular aluminium ions, being removed from the blood during the dialysis treatment without the risk of serious side effects for the patient. 2.2 This problem is solved by an apparatus, in particular a dialyser 10, in which the blood circulation (100, 30, 120) has, upstream of the dialyser (10), not only a source (150) of an anticoagulant, in particular heparin, but also another source (170) which has a solution which complexes aluminium ions and which is connected to the blood supply line (100) of the blood circulation (100, 30, 120). A pump (220) can be used to supply predetermined amounts of solution which complexes aluminium ions from the other source (170) to the blood circulation (100, 30, 120). The anticoagulant source (150) and complexing source (170) may be combined in a common source (150, 170) which preferably has either membrane-crossing heparin or a mixture of citrate or membrane-crossing heparin with essentially non-dialysable heparin.</p> |
