Abstract:
A hemofiltration system, comprising:a hemofilter; a first panel comprising first and second sheets of material sealed to form a first fluid pathway and a first chamber, the first fluid pathway passing a volume of a waste fluid to the first chamber, the first fluid pathway and first chamber free of an air interface; a second panel comprising first and second sheets of material sealed to form a second fluid pathway and a second chamber, the second fluid pathway passing a volume of a replacement fluid to the second chamber, the second fluid pathway and second chamber free of an air interface, wherein the first and second panels are arranged in overlapping fashion and aligned so that the first chamber overlays the second chamber to form a structure so that the first fluid from the first chamber is displaced as the second fluid fills the second chamber; a sensor operatively associated with at least one of the first or second panels to measure fluid pressure in the first or second fluid pathway; and an extracorporeal circuit for circulating blood from an individual through the hemofilter to remove waste and to return blood and replacement fluid to the individual after removal of waste while the first and second panels operate to balance the volume of removed waste fluid with the volume of replacement fluid.
