摘要： A non-invasive device for measuring blood temperature in a circuit for the extracorporeal circulation of blood includes a line in which blood taken from a patient flows. The device also includes a temperature sensor connected to the line and provided with a device for measuring the intensity of an electromagnetic radiation. The measuring device faces a connecting portion or window of the line that is permeable by electromagnetic radiation in a first wave band, and generates a first signal, correlated with the electromagnetic radiation in the first band and therefore with the temperature of the blood flowing in the line.

摘要： A method for measuring the hemoglobin concentration in the blood in a circuit of a dialysis machine includes directing electromagnetic waves against one section of the circuit, measuring values of the electromagnetic waves transmitted through the section, and determining values of absorption of electromagnetic waves by the blood along the section from the measured values of transmitted electromagnetic waves. The values of absorption are correlated with the values of the hemoglobin concentration. The method also includes measuring the values of at least one physical quantity of the blood, wherein the at least one physical quantity is selected from blood pressure and blood temperature, and calculating the values of hemoglobin concentration as a function of the values of absorption and the at least one physical quantity.

摘要： An extracorporeal blood treatment apparatus comprises a sensor (10) for emitting a signal indicating a change of hematic volume of an individual (7) subjected to a treatment and a weight loss system for actuating the individual's weight loss. A control unit (20) receives an effective weight value of the individual and a desired weight loss value and from these values determines a desired value of a change in hematic volume at end of treatment. The weight loss system is controlled on a basis of the hematic volume change signal and the desired value of the hematic volume change. The apparatus enables automatic control of a dialysis operation while preventing some complications arising from hypotension.
