An apparatus for extracorporeal blood treatment comprises a sensor () for emitting a signal indicating a variation in blood volume (&#x394;Bv&#x2033;) of an individual () subjected to extracorporeal blood treatment and a sensor () for emitting a signal indicating a weight loss of the individual. A control unit () receives the signals, compares the ratio between the relative variation of blood volume (&#x394;Bv/BV) and the relative variation of weight loss (AWL/TW) of the individual with a desired value, and controls the weight loss of the individual on the basis of the comparison. The apparatus enables automatically controlling a dialysis, preventing some complications due to hypotension.

Apparatus and a method for extracorporeal blood treatment

An apparatus for extracorporeal treatment of blood () comprising a treatment unit, a blood withdrawal line, a blood return line, a preparation line and a spent dialysate line. A control unit () is configured to calculate values of a parameter relating to treatment effectiveness based on measures of the conductivity in the spent dialysate line. The value of the effectiveness parameter is calculated using one or more values representative of the conductivity in the spent dialysate line obtained relying on a mathematical model.

Apparatus for determining a parameter indicative of the progress of an extracorporeal blood treatment

An apparatus is described for extracorporeal blood treatment, comprising a treatment unit, an extracorporeal blood circuit and a fluid evacuation line. The apparatus comprises a control unit connected to a pressure sensor and configured to move a blood pump, generating a variable flow with a constant component equal to a desired blood flow value and a variable component having a nil mean value; the variable flow generates, in the expansion chamber, a pressure progression that is variable over time with a pressure component oscillating about a mean value. The control unit receives a plurality of values over a period of time comprising a plurality of oscillations of the pressure about the mean value, calculates a control value representative of the oscillating pressure component, and then determines the verification or not of a condition of variation of the blood level in the expansion chamber.

Disposable extracorporeal blood circuit and apparatus for the extracorporeal treatment of blood

An extracorporeal blood treatment apparatus comprises a sensor () for emitting a signal indicating a change of hematic volume of an individual () subjected to a treatment and a weight loss system for actuating the individual's weight loss. A control unit () 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.
