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.
