Abstract

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.
