Priming and air removal systems and methods for dialysis
First Claim
1. A renal treatment fluid priming method comprising:
- priming an extracorporeal circuit connected to a patient with a physiologically compatible fluid, the extracorporeal circuit including an arterial line, a venous line and blood compartment of a blood filter; and
pumping from a renal treatment fluid line in communication with the blood filter (i) pulling blood from the patient through the arterial line to flush the physiologically compatible fluid through the arterial line and the blood filter compartment into the renal treatment fluid line and (ii) pulling blood from the patient through the venous line to flush the physiologically compatible fluid through the venous line and the blood filter compartment into the renal treatment fluid line,such that a greater volume of blood is pulled from the patient via (i) and (ii) than a volume of the extracorporeal circuit.
