Dialysis system and method therefor
First Claim
1. A dialysis system comprising a dialyzer having (i) a dialysis liquid input side and a dialysis liquid output side for the flow of a dialysis liquid therethrough, and (ii) a blood input side and a blood output side for the flow of blood therethrough, control means for controlling one or more parameters of the dialysis liquid at a non-measured desired set value on the dialysis liquid input side of said dialyzer, measuring means for measuring the value of at least one of said parameters of said dialysis liquid on the dialysis liquid output side of said dialyzer, and comparison means for comparing the value of the measured parameter with the non-measured desired set value of the corresponding parameter being controlled by said control means.

Abstract
A dialysis system and method is based upon a comparison of the value of a parameter being measured of the dialysis liquid after the dialyzer with a set value of the corresponding parameter being controlled before the dialyzer. Based upon this comparison, a measure of the dialysis performed is obtained, and with the assistance of this measured value, as well as the knowledge of other factors, for example, adjusted values relevant for the analysis, conditions of the patient'"'"'s blood can be determined theoretically and thereby controlled.
