1. A respiratory pressure treatment device for a patient, the respiratory pressure treatment device comprising:
a pressure generator configured to supply a flow of air at positive pressure air;
a humidifier apparatus configured to humidify the flow of air for delivery to the patient, the humidifier apparatus being integrated in the respiratory pressure treatment device, the humidifier apparatus comprising:
a dock comprising a spring-biased heater plate and a recess; and
a water reservoir configured to be engaged with the dock and comprising a chamber that is, when the water reservoir is in an operative position with the dock, in fluid communication with the flow of air, the water reservoir further comprising:
a base structured to hold a volume of water and including a conductive portion in thermal engagement with the heater plate when the water reservoir is received on the dock;
a lid movably connected to the base between a closed position and an open position, the lid including an upper surface that is exposed when the water reservoir is secured in the operative position and in sealed fluid communication with the dock;
a seal that seals between the base and the lid when the lid is in the closed position; and
a protrusion configured to be locked within the recess to secure the reservoir to the dock in the operative position, the protrusion including an exterior portion extending outward from an exterior surface of the water reservoir when the base and the lid are in the closed position, the protrusion being spaced from and distinct from the upper surface that is exposed when the water reservoir is secured in the operative position, the protrusion not being exposed when the water reservoir is secured in the operative position and in sealed fluid communication with the dock; and
a resilient portion configured to be compressed upon direct application of a downwards force to the upper surface of the water reservoir lid that is exposed whilst the water reservoir is secured in the operative position and in sealed fluid communication with the dock to unlock the protrusion from within the recess and thus enable removal of the reservoir from the dock.
