Abstract
A method of sealably locating a humidifier water tub in a humidifier base comprising positioning a rear surface of the humidifier water tub to abut a humidifier seal to form an air path from a flow generator outlet into an interior of the water tub, and pressing a humidifier lid of the humidifier to engage a surface of a tub lid of the humidifier water tub to form a sealed air path between an interior of the humidifier water tub and an air delivery conduit connector positioned on the humidifier lid.

96. In a humidifier assembly for a flow generator used in delivery of a supply of breathable gas to a patient for treatment of sleep disordered breathing, the humidifier assembly comprising a water tub having an inlet, a base having a blower outlet and a water-tub-receiving-portion, and a hinged lid with an engagable locking mechanism, a method of forming a seal between the water tub inlet and the blower outlet of the base comprising the steps of:
- (i) placing the water tub in the tub-receiving-portion of the base so as to position the inlet and the outlet adjacent one another;
(ii) closing the hinged lid; and
(iii) engaging the locking mechanism. - View Dependent Claims (97, 98, 99)

122. In a humidifier assembly for a flow generator used in delivery of a supply of breathable gas to a patient for treatment of sleep disordered breathing, the humidifier assembly comprising a water tub having an inlet, a base having an aperture adapted to communicate with output from the flow generator and a water-tub-receiving-portion, and a hinged lid with an engagable locking mechanism, a method of forming a seal between the water tub inlet and the aperture of the base comprising the steps of:
- (i) placing the water tub in the tub-receiving-portion of the base so as to position the inlet and the outlet adjacent one another;
(ii) closing the hinged lid to establish the seal with the water tub inlet; and
(iii) engaging the locking mechanism. - View Dependent Claims (123, 124, 125)
