  • Patent number: 11020518
    Abstract: An apparatus for extracorporeal blood treatment comprises a sensor (10) for emitting a signal indicating a variation in blood volume (?Bv?) of an individual (7) subjected to extracorporeal blood treatment and a sensor (14) for emitting a signal indicating a weight loss of the individual. A control unit (20) receives the signals, compares the ratio between the relative variation of blood volume (?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.

  • Patent number: 9821106
    Abstract: 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.

  • Patent number: 8684959
    Abstract: 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.
