Hemodialysis system

A blood circuit assembly for a dialysis unit, comprising:

• a pair of pneumatic pumps for circulating blood received from a patient through a circuit including a dialyzer unit and returning the blood to the patient, the pneumatic pumps having pneumatic control ports arranged for alignment and mating with corresponding ports located on an exposed panel of the dialysis unit by pushing the control ports into engagement with the corresponding ports with mounting of the blood circuit assembly to the exposed panel;
• an air trap having an inlet and an outlet arranged to remove air from blood circulating in the circuit;
• a single unitary member that defines, at least in part, the pumps, a retaining member for the air trap and a plurality of routing channels for flexible tubing, the plurality of routing channels including a routing channel for a tube extending from the outlet of the air trap to an occluder position, the retaining member for the air trap being configured to support the air trap at a location above a lowermost part of the routing channel for the tube and above an air-in-line detector configured to detect air in the tube;
• a pair of dialyzer connections arranged to connect to the inlet and outlet of a dialyzer unit;
• a pair of blood line connectors, including an arterial blood line connector for receiving blood from the patient and providing blood to the pneumatic pumps and a venous blood line connector for returning blood to the patient;
• and
• flexible tubing fluidly connecting the pumps, the air trap, the dialyzer connections and the blood line connectors.
