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 iron the group comprising the blood pressure (1)), the blood temperature (T) and the rate of flow (Q_b) 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
