Abstract:
In a hemodialysis method, a method for priming a blood compartment of a hemodialyzer, the method comprising:(a) providing a liquid;(b) conducting the liquid through a first positive displacement pump, then through a first flowmeter, then to a dialysate inlet of a dialysate compartment of the hemodialyzer, the first pump delivering the liquid to the dialysate inlet at a first volumetric pumping rate as measured by the first flowmeter;(c) after passing the liquid through the dialysate compartment, conducting the liquid from an outlet of the dialysate compartment through a second flowmeter, then through a second positive displacement pump, the second pump pumping the liquid at a second volumetric pumping rate, as measured by the second flowmeter, that is less than the pumping rate of the first pump so as to urge net flow of the liquid from the dialysate compartment to the blood compartment of the hemodialyzer.
