摘要：
A tub or tank for holding fluid to be humidified as part of sleep apnoea breathing device, comprising a bottom surface and a plurality of walls forming a cavity configured to hold a predetermined maximum volume of water when the water reservoir is in a working orientation, the bottom surface of the water reservoir defining a bottom plane that is substantially horizontal when the water reservoir is in the working orientation, the water reservoir including an inlet tube (5124) providing an inlet flow path for a flow of pressurized breathable gas entering the cavity, the inlet tube including an inlet tube outer end arranged in one of the plurality of walls, an inlet tube inner end arranged within the cavity, and an inlet tube axis defined between the inlet tube inner end and the inlet tube outer end, the water reservoir including an outlet tube (5126) providing an outlet flow path for a flow of humidified, pressurized breathable gas exiting the cavity, the outlet tube including an outlet tube inner end arranged within the cavity, an outlet tube outer end arranged in one of the plurality of walls, and an outlet tube axis defined between the outlet tube inner end and the outlet tube outer end, wherein the inlet tube axis is oriented at a first angle relative to the bottom plane and the outlet tube axis is oriented at a second angle relative to the bottom plane, the first angle being different than the second angle, wherein the inlet tube and the outlet tube are arranged such that: at least one of the inlet tube inner end and the inlet tube outer end is above a level of the predetermined maximum volume of water when the water reservoir is in the working orientation and when the water reservoir is rotated by 90 degrees in at least one direction from the working orientation； and at least one of the outlet tube inner end and the outlet tube outer end is above a level of the predetermined maximum volume of water when the water reservoir is in the working orientation and when
