Blood rinseback system and method

Abstract:

A hemodialysis system is provided and includes a dialyzer, a dialysis fluid circuit in fluid communication with the dialyzer, a blood circuit, a blood detector and a blood rinseback scheme, wherein the blood rinseback scheme includes transferring blood to the patient using a physiologically acceptable fluid, wherein the physiologically acceptable fluid is introduced from its source into an arterial line between an arterial line patient end and a blood pump of the blood circuit, and flowed through the dialyzer, through a venous drip chamber and to the blood detector along a venous line of the blood circuit, where the physiologically acceptable fluid is sensed by the blood detector to indicate an end of the blood rinseback.
