Verfahren zur Eichung eines Paares von Sensoren in einem Dialysatkreislauf.

摘要

The calibration procedure for a pair of sensors (De,Ds) on the inlet and outlet sides of a blood dialysis system consists of performing an initial calibration with the system (4) in a short-circuited mode to determine the response factor of each sensor and to define an initial calibration coefficient, followed by a correction phase while the system is in operation. The procedure incorporates at least one phase for determining an auxiliary calibration coefficient for the inlet sensor, using an auxiliary sensor (Da) which is of the same time as the inlet and outlet sensors, defining the response factors for the inlet and auxiliary sensors, and defining the auxiliary calibration coefficient for the inlet sensor which allows an equal measuring value to be obtained for the inlet and auxiliary sensors. A similar procedure is carried out with the auxiliary and outlet sensors to produce the auxiliary calibration coefficient for the latter.
