A METHOD FOR MEASURING HEMOGLOBIN CONCENTRATION (HGB) IN THE BLOOD IN A CIRCUIT OF A DIALYSIS MACHINE, MEASURING DEVICE AND CIRCUIT FOR THE APPLICATION OF THE METHOD

摘要

A method for measuring the hemoglobin concentration (HGB) in the blood in a circuit (2) of a dialysis machine (1), the method comprising the measurement of the values of absorption (A) of electromagnetic waves by the blood conveyed along a specified section (5a) of the said circuit (2), the measurement of the values of a physical quantity from the group comprising the blood pressure (P), the blood temperature (T) and the rate of flow (Qb) of the blood along the aforesaid section (5a), and the calculation of the hemoglobin concentration (HGB) as a function of the values of absorption (A) and of the aforesaid physical quantity.
