Abstract: An apparatus for extracorporeal blood treatment comprising a filtration unit, a blood circuit comprising a blood with-line and a blood return line, and a fluid circuit. The fluid circuit comprises at least one or more water inlet ducts for receiving water, a dialysis preparation assembly comprising one or more concentrated sources housing a respective concentrate solution and configured to prepare a mixed solution of a dialysis fluid, wherein the water inlet duct is configured to provide water to the dialysis preparation assembly for preparing said mixed solution of dialysis fluid. The fluid circuit further comprises an infusion preparation assembly comprising one or more concentrated sources housing a respective concentrate solution and configured to prepare a mixed solution of an infusion fluid, wherein the water inlet duct is configured to provide water to the infusion preparation assembly for preparing said mixed solution of infusion fluid.

Abstract: An apparatus (1) for extracorporeal blood treatment comprises a filtration unit (2) having a primary chamber (3) and a secondary chamber (4) separated by a semi-permeable membrane (5), a blood circuit (17) comprising at least a blood withdrawal line (6) and a blood return line (7), a fluid circuit (32) comprising a fluid supply source (50) for providing a sterile fluid, and at least one gas inlet (49) to allow gas to enter into the blood circuit (17). The apparatus further comprises a control unit configured to perform a blood restitution procedure towards the patient for ending an extracorporeal blood treatment and before disconnecting the patient, said blood restitution procedure comprising the steps of infusing a predetermined amount of sterile fluid from the supply source (50) into the blood circuit (17) and causing a predetermined amount of gas to enter into the blood circuit (17) from the gas inlet (49).
