Hemodialysis with dialysate osmolarity varied non-linearly with time

摘要

The invention is concerned with a hemodialysis technique employing a dialyzer having a blood flow compartment separated from a dialysate flow compartment by a semi-permeable membrane. According to the invention, this technique is improved by providing for the osmolarity of the dialysate to be increased as a function of time during at least a portion of the total treatment time, whereby dialysis disequilibrium syndrome problems can be alleviated.
