1. A respiratory pressure therapy (RPT) device for pressurizing and humidifying breathable air to treat a respiratory disorder in a patient, the RPT device comprising:
a blower configured to pressurize the breathable air;
a water reservoir comprising a water reservoir base configured to hold a volume of water to be used for humidification of the breathable air, the water reservoir further comprising a water reservoir lid connected to the water reservoir base, and the water reservoir including a water reservoir inlet and a water reservoir outlet positioned on an insertion side of the water reservoir, the water reservoir having an inside portion and an outside portion, the outside portion having a width that is greater than a width of the inside portion; and
a water reservoir dock that forms a cavity configured to receive the inside portion of the water reservoir, the water reservoir dock and the water reservoir being shaped and dimensioned such that the outside portion of the water reservoir is positioned outside of the cavity when the insertion side of the water reservoir is slidingly received in, sealingly engaged with and secured to the water reservoir dock, the outside portion having a first handling surface positioned on the water reservoir lid, configured to face upwards when the water reservoir is in an in-use orientation, and configured to be grasped by the patient, the outside portion having a second handling surface positioned on the water reservoir base, configured to face downwards and be positioned underneath the first handling surface when the water reservoir is in the in-use orientation, and configured to be grasped by the patient, the second handling surface being formed by a wall of the water reservoir base that is configured to hold the volume of water, and the first handling surface and the second handling surface being exposed when the water reservoir is slidingly received in, sealingly engaged with, and secured to the water reservoir dock,
the water reservoir base having a pair of lateral edges along opposite exterior sides of the water reservoir, at least a portion of the lateral edges being substantially parallel to one another, each of the lateral edges including an exterior shoulder forming a substantially horizontal edge surface extending along a portion of a respective exterior side of the inside portion of the water reservoir, at least one of the substantially horizontal edge surfaces extending along the lateral edge from proximate the insertion side of the water reservoir, a transitional wall that extends outwardly from the inside portion to connect with the outside portion forming a transition from the inside portion to the outside portion, at least one exterior shoulder of the exterior shoulders including an exterior lug that extends from and projects upwardly from the substantially horizontal edge surface, the exterior lug being positioned between the insertion side and the transitional wall,
the water reservoir dock includes a pair of sliding rails positioned within the cavity, each said sliding rail being formed along a side wall within the cavity, the pair of sliding rails positioned on opposite side walls of the water reservoir dock within the cavity, each of the sliding rails including a guide surface that faces downwards, wherein, as the inside portion of the water reservoir slides at least partly into the cavity, and the exterior lug being positioned between the substantially horizontal exterior edge surface of the at least one exterior shoulder and the guide surface of the sliding rail.
