Patent number: 11020518Abstract: 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.Type: GrantFiled: October 15, 2018Date of Patent: June 1, 2021Assignee: Gambro Lundia ABInventors: Francesco Fontanazzi, Francesco Paolini, Fabio Grandi

Patent number: 9821106Abstract: 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.Type: GrantFiled: July 26, 2017Date of Patent: November 21, 2017Assignee: Gambro Lundia ABInventors: Alessandro Vasta, Francesco Fontanazzi, Mauro Suffritti
