    摘要： A method and device for adjusting a volumetric flow balancing system for an extracorporeal blood treatment system receives a pressure signal and calculates a compensation factor that is used to adjust the relative flow rates of the volumetrically balanced fluids. For example, in a hemofiltration system, the flow of waste and and replacement fluid may be balanced volumetrically. Ultrafiltrate may be pumped in a bypass circuit in such a system. The rate of ultrafiltrate flow may be adjusted by the compensation signal. The compensation signal may be empirically derived.

    摘要： A method and device for renal replacement therapy is described that sterile-filters solution that can subsequently be used as a replacement fluid in the same unit. The devices and methods include a pump that can be reversed from its normal forward-pumping direction to sterilize a container of replacement fluid to produce sterile replacement fluid. The sterile replacement fluid is captured in a fluid bag. Upon sterilization of the contents of the container, the pump switches to run in its normal forward-pumping direction. The sterile replacement fluid produced by the previous process is now injected into a patient to perform renal replacement therapy. The waste produced during the renal replacement therapy can be trapped in the container that previously held the non-sterile solution. Systems for sterile filtration and subsequent renal replacement therapy that include pre-connected, sterilized, disposable kits for fluid management and batch collection of sterilized fluid are also described.

    摘要： Systems and methods balance fluid in a fluid processing procedure during which an outgoing fluid is removed from an individual and an ingoing fluid is supplied to the individual. The systems and methods supply a volume of the outgoing fluid and a volume of the ingoing fluid into a volumetric chamber. The systems and methods discharge a volume of the outgoing fluid and a volume of the ingoing fluid from the volumetric chamber. The systems and methods synchronizes the supply and discharge of fluid to affect a concurrent discharge of the outgoing fluid and ingoing fluid from the volumetric chamber in volumetric balance with a concurrent supply of outgoing fluid and ingoing fluid into the volumetric chamber. The volumetric chamber can include at least one chamber including an interior wall dividing the chamber into a first compartment and a second compartment. The first compartment retains a volume of outgoing fluid. The second compartment retains a volume of ingoing fluid. The interior wall responds to differential fluid pressure to discharge the ingoing fluid from the second compartment as the outgoing fluid is conveyed into the first compartment, and vice versa.
