A modular assembly for a portable hemodialysis system may include a dialysis unit, e.g., that contains suitable components for performing hemodialysis, such as a dialyzer, one or more pumps to circulate blood through the dialyzer, a source of dialysate, and one or more pumps to circulate the dialysate through the dialyzer, and a power unit having a housing that contains suitable components for providing operating power to the pumps of the dialysis unit. The power unit may be selectively connected to the dialysis unit and provide power (e.g., pneumatic power in the form of pressure and/or vacuum) to the dialysis unit for the pumps when connected to the dialysis unit, but may be incapable of providing power to the dialysis unit when disconnected from the dialysis unit. The dialysis unit and the power unit are sized and weighted to each be carried by hand by a human.

The system of claim 1, wherein the blood circuit connections at the front opening include arterial and venous blood line connectors, and the dialysate fluidic connections at the front opening include a connection point for an acid or bicarbonate source, connection points for dialyzer dialysate connections, and a blood line connection point for connecting the arterial and venous blood line connectors to a drain circuit of the dialysis unit. 16. The system of claim 1, further comprising a control interface that is connected to the dialysis unit housing by a flexible cable, the control interface being arranged to allow a user to receive information from and provide information to the hemodialysis unit. 17. The system of claim 16, wherein the dialysis unit housing includes a control interface mounting area at a top of the housing where the control interface is mountable. 18. The system of claim 16, wherein the dialysis unit housing includes at least one door that is movable to expose the front opening. 19. The system of claim 18, wherein the at least one door includes a hook to support the control interface. 20. The system of claim 18, wherein the dialysis unit housing includes a pair of vertical, side-by-side doors. 21. The system of claim 20, wherein at least one of the doors includes a seal to resist air exchange between an interior and an exterior of dialysis unit housing when the doors are in a closed position. 22. The system of claim 1, wherein the electronics section includes pneumatic controls for controlling flow of control fluid for the one or more pumps of the dialysis unit.
