  • Patent number: 10918775
    Abstract: An apparatus and a method for extracorporeal blood treatment, especially for hemodialysis, wherein blood of a patient is flushed with a dialysate in a dialyzer and wherein a variable correlated with the plasma sodium concentration of the blood is measured. The composition of the dialysate then is adjusted in response to the variable measured so that the plasma sodium concentration of the blood at least at the end of the blood treatment has the same value as at the beginning. For measuring the variable correlated with the plasma sodium concentration of the blood, for example a bypass operation can be implemented in which the dialysate is guided past the dialyzer so that a residual volume on the side of the used dialysate at least partially adopts the concentration of the substances dissolved on the blood side.

  • Patent number: 10905817
    Abstract: Described is a method for controlling fluid volume balance. A controller is configured with a first set of inputs comprising a hematocrit, a total blood volume, and an ACD ratio. A maximum extracorporeal RBC amount during the procedure is estimated based on the first set of inputs. A fluid circuit is primed with a priming fluid. Whole blood is drawn from a blood source and separated into a RBC component, a target cell component, and a plasma component. The target cell component is directed to a product container. The product container comprising the target cell component is treated. A treated target cell component, a portion of the RBC component remaining in the fluid circuit, and/or a portion of the plasma component remaining in the fluid circuit are returned to the blood source. A first response action is provided if the maximum extracorporeal RBC amount estimated is above a programmed limit.
