BLOOD RINSEBACK SYSTEM AND METHOD

Abstract:

A hemodialysis system includes a dialyzer; a dialysis fluid circuit including a fresh dialysis fluid pump, and a used dialysis fluid pump; a blood circuit including a blood pump operable with an arterial line upstream of the dialyzer, a medical fluid source in fluid communication with the arterial line between a patient end of the arterial line and the blood pump, a drip chamber located along a venous line; a blood rinseback sequence wherein blood is transferred to the patient by the medical fluid, wherein the medical fluid is introduced from its source into the arterial line between an arterial line patient end and the blood pump, and flowed through the dialyzer, through the venous drip chamber along the venous line; and a blood circuit priming sequence initiated in the blood circuit via the arterial line.
