Abstract
A hemodialysis system configured to purge air from a blood circuit comprises a dialyzer; a dialysis fluid circuit operable with the dialyzer via dialysis fluid inlet and outlet lines, the dialysis fluid circuit including a fresh dialysis fluid pump, and a used dialysis fluid pump; the blood circuit operable with the dialyzer and including an arterial line, a venous line, a blood pump operable with the arterial line upstream of the dialyzer, a physiologically acceptable fluid source in fluid communication with the arterial line upstream of the blood pump, a drip chamber located along the venous line, and a container for accepting air purged from the blood circuit; and an air purging scheme wherein, with the dialysis fluid inlet and outlet lines connected to the dialyzer, the blood pump pumps a fluid through the dialyzer and into the drip chamber, forcing air from the drip chamber into the container.
