Fluid replacement systems and methods for use in association with a hemofilter convey an individual's blood through an extracorporeal fluid circuit to the hemofilter to remove waste fluid. The systems and methods convey waste fluid from the hemofilter through a waste line. The systems and methods convey blood from the hemofilter through a blood return line after removal of waste fluid. The systems and methods balance the removal of waste fluid with replacement fluid. The systems and methods can selectively operate in a bolus mode, to increase the volume of replacement fluid supplied to the individual. The systems and methods can also selectively operate in a rinse back mode, during which a volume of replacement fluid circulated into the blood return line, to thereby flush the blood return line.

A method of forming a hollow cured composite aircraft structure using a single cure resin transfer molding process, comprising: positioning a first fiber material piece at least partially around an outer surface of at least one mandrel, said first material piece comprising a dry fiber material piece; positioning a second fiber material piece adjacent said first fiber material piece with a separating film disposed therebetween to form an uncured composite aircraft structure, wherein said separating film has opposing first and second surfaces, and wherein at least one surface of said first material piece is positioned in contact with said first surface of said separating film and at least one surface of said second material piece is positioned in contact with said second surface of said separating film; positioning said uncured composite aircraft structure and said mandrel within a closed mold cavity; introducing a first resin into said closed mold cavity to contact and at least partially impregnate said first fiber material piece with said first resin; allowing said first resin that at least partially impregnates said first fiber material piece to cure within said mold cavity during a single cure cycle to form at least a portion of a cured composite aircraft substructure; allowing a second resin that at least partially impregnates said second fiber material piece to cure within said mold cavity during said single cure cycle to form at least a portion of a cured composite aircraft structure skin, said cured composite aircraft substructure and said cured composite aircraft structure skin together forming a cured composite aircraft structure; removing said cured composite aircraft structure from said closed mold cavity; and removing said mandrel from said cured composite substructure to form said hollow cured composite aircraft structure; wherein said separating film is substantially impermeable to said first and second resins so that said separating film substantia
