Abstract

A water reservoir for use with a medical treatment apparatus includes a reservoir base including a cavity structured to hold a volume of water to humidify a supply of pressurized breathable air. The reservoir base includes a heat conductive portion, wherein the heat conductive portion is configured to thermally engage with a heating assembly of a water reservoir dock associated with the medical treatment apparatus to allow thermal transfer of heat from the heating assembly to the heat conductive portion. The water reservoir includes at least one protrusion that protrudes outwardly from a side of the reservoir base, wherein the at least one protrusion is configured to be fully inserted into at least one slot on a side of the water reservoir dock, and wherein the at least one protrusion only extends partially along the side of the reservoir base.
