FLUID REPLACEMENT SYSTEMS AND METHODS FOR USE IN HEMOFILTRATION

摘要

Fluid replacement systems and methods for use in association with a hemofilter (34) 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 (66). The systems and methods convey blood from the hemofilter through a blood return line (64) 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.
