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.
L'invention concerne un procédé de mesure de la concentration de l'hémoglobine (HGB) dans le sang dans un circuit (2) d'une machine à dialyse (1). Ce procédé consiste à mesurer les valeurs d'absorption (A) d'ondes électromagnétiques par le sang transportées le long d'une section spécifiée (5a) dudit circuit (2). Les mesures des valeurs d'une quantité physique provenant du groupe constitué de la pression sanguine (P), de la température du sang (T) et de la vitesse du débit (Q¿b?) de sang dans la section susmentionnée (5a) et le calcul de la concentration de l'hémoglobine (HGB) comme un fonction des valeurs d'absorption (A) et de la quantité physique susmentionnée.
