Abstract: The invention relates to a blood treatment device by extracorporeal circulation comprising a filter having a primary chamber and a secondary chamber separated by a semi-permeable membrane; a blood circuit comprising an arterial line intended to come from the patient, the filter's primary chamber and the venous line intended to return to the patient; a dialysate circuit comprising the filter's secondary chamber and at least a drain line for circulating the waste intended to come from the filter and intended to go to a drain; a first bag in fluid communication with the drain line; at least a first gravimetric weighing means linked to the first bag, fluid flow rate adjustment means acting on the drain line; a control unit linked to the first gravimetric weighing means and with the fluid flow rate adjustment means; a second bag in fluid communication with the drain line, the control unit being capable of receiving weight signals from the first gravimetric weighing means and of controlling the fluid flow rate adju

Abstract: A device for the extracorporeal treatment of blood comprising at least one exchanger (1) comprising a semi-permeable membrane (6) dividing said exchanger into a first chamber (7) and a second chamber (8), at least one first inlet (2) for blood to be treated being in fluid communication with the first chamber (7) of the exchanger, a first fluid outlet (4) being in fluid communication with the first chamber (7) of the exchanger and a second fluid outlet (5) being in fluid communication with the second chamber (8) of the exchanger, an input line (10) for blood to be treated connected to the first inlet (2) of the exchanger (1), a blood output line (11) connected to the first outlet (4) of the exchanger (1), at least one treatment unit (21) comprising a semi-permeable membrane (26) dividing the treatment unit (21) into a first chamber (27) and a second chamber (28), at least one first fluid inlet (22) being in fluid communication with the second chamber (28) of the treatment unit (21) and at least one first fluid

Abstract: The invention concerns a device for treating blood by extracorporeal circulation (101) comprising a filter (102) having a first chamber (103) and a second chamber (104) separated by a semi-permeable membrane (105), an arterial line (106) connected to the first chamber (103) of the filter (102), a venous line (108) issuing from the first chamber (103) of the filter (102), a channel (109) used for pre-infusion of a substance for regional anticoagulation and linked to the arterial line (106), a purge channel (110) issuing from the second chamber (104) of the filter (102), an air separator (112) on the venous line (108), a line (112) for post-infusion of a solution at least partially re-establishing the ionic equilibrium of the blood downstream of the air separator (111), and an air detector (113) downstream of the post-infusion line (112).
