Abstract
The specification discloses a portable dialysis machine having a detachable controller unit and base unit with an improved reservoir heating system. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The base unit has a reservoir with an internal pan and external pan, separated by a space that holds a heating element. The heating element is electrically coupled to electrical contacts attached to the external surface of the external pan.
