Dialysis soln. for use with artificial kidneys - contains low calcium ion content, but high citrate content to inhibit coagulation of blood

摘要

A dialysis soln. for use with artificial kidneys contains at most 0.2 mMol/l la and 5-55 mMol/l citrate ions and 130-165 mMol/l Na ions. A device for dialysis treatment with artificial kidneys consists of a dialysis cell (3), a conveyor pump (8) for the patients blood and a conveyor pump (9) for the dialysate soln. A dosing pump (6) is situated in pipe (15) for recycling blood after the dialysis cell (3). This pump adds Ca2+ and/or Mg2+ ions from a container to the patients blood. USE/AVANTAGE - The high citrate ion content ensures that citrate ions diffuse into the blood and act in the membrane filter as anticoagulants. The citrate ions are degraded in the body by the Krebs cycle. Citrate intoxication is prevented by ensuring that the content of free ionised Ca is low and the Ca2+ is continuously added to the blood after the dialysis. Thus the use of heparin is avoided.
