Abstract
A hemodialysis system comprising: a source of priming fluid; an extracorporeal circuit including an arterial line, a venous line, and a drip chamber; a level sensor operable with the drip chamber; a reversible blood pump operable with the extracorporeal circuit; a connection between the arterial and the venous line; and a priming sequence in which priming fluid from the source is pumped in a reverse pump direction through the extracorporeal circuit and reversibly in a normal pump direction through the extracorporeal circuit, wherein an output from the level sensor is used to determine when to stop pumping in at least one of the directions.
