Abstract:
A layered fluid circuit (56) includes first (232) and second (234) panel sections formed from sealed sheets (230A/230B) of flexible material. A pattern of seals (S) is formed in the first panel section to define a first fluid circuit. A pattern of seals is formed in the second panel section to define a second fluid circuit. The flexible sheets are aligned to place the first and second panel sections in a relationship with the first fluid circuit overlaying the second fluid circuit. The layered fluid circuit can be placed in a tray (48) for use. Defined operating regions can be formed in one or both fluid circuits, such as in-line clamping regions (224), in-line pump tubes (155/145/201), in-line sensor regions (204), in-line fluid holding compartments (212/214), or combinations thereof.
Abstract:
System 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 and ingoing fluids from the volumetric chamber in volumetric balance with a concurrent supply of outgoing and ingoing fluids into the volumetric chamber. The volumetric chamber can include at least one chamber including an interior wall dividing the chamber into first and second compartments. The first and second compartments retain a volume of outgoing and ingoing fluids respectively.
