摘要：
A breathable gas supply apparatus for treatment of respiratory disorders comprising a flow generator with an air inlet (807) on a rear wall (803), the air inlet configured to provide a supply of ambient air to a blower of the flow generator； a water tub (698) with a first air opening, a second air opening, a top portion, a side surface configured to face the rear wall in use and having the second air opening therein and a bottom portion, the bottom portion having a heat conducting surface； a base (602, 803) with a heater (800), the base being configured to receive the water tub； a lid (700)； a rotatably engageable catch (646) for the lid, the catch securing the water tub in the base in use； a seal (699) between the lid and the top portion of the water tub； an outlet pipe for connection with an air delivery tube in use； a first gas flow port aligned with and in a facing arrangement with the first air opening； a second gas flow port in a facing arrangement with the second air opening； and a peripheral seal (722) between the second gas flow port and the second air opening to create a sealed air path therebetween. The water tub and the base include complementary configurations (698, 632) that facilitate alignment of the water tub with respect to the base to ensure alignment between the second air opening and the second gas flow port. When the catch is engaged, downwards pressure is maintained on the water tub to maintain heat-transfer contact between the bottom portion of the water tub and the heater. The water tub can be removed and refilled with water without requiring disengagement of the air delivery tube from the outlet pipe. The first air opening, the second air opening, the first gas flow port and the second gas flow port are part of a flow path between the flow generator and the outlet pipe.
