Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a front surface and a rear surface, opposite the front surface, and adapted in use to face the patient. The frame defines an inner wall and an outer wall extending from the rear surface, the inner and outer walls being spaced to define a channel therebetween. A cushion is removably attachable to the frame such that the cushion and frame are repeatably engagable with and disengagable from one another. The cushion includes a side wall to be inserted into the channel of the frame, the side wall having a first interlocking surface that engages a second interlocking surface provided in the channel when the cushion and frame are engaged with one another. The first and second interlocking surfaces interlock with one another to removably attach the cushion to the frame.

Abstract: A method and system for providing health task notifications to users. In one embodiment, the method comprises establishing a schedule for the delivery of health task notifications or reminders. The schedule may be entered by the user or provided as an editable default schedule based on the user's inputted health goals. Notifications and/or reminders are then provided according to the schedule. The system includes a means by which the user may interact with the messages to provide a response. For example, the user may acknowledge, dismiss, and/or delay the message. Based on the user's interaction, the message display is completed or reiterated at a predetermined delay time. In some instances, the schedule may also be updated based on the user's response.

Abstract: A patient interface includes a frame having a circular opening to receive pressurized gas and a cushion supported on the frame and defining a breathing chamber configured to receive the pressurized gas. The patient interface further includes support structure configured to support the patient interface on the patient's head, a plurality of gas washout holes configured to vent gas from the breathing chamber to atmosphere, and an elbow assembly. The elbow assembly includes a rotatable elbow that is releasably snap-fittable to the frame. The rotatable elbow having a pair of diametrically opposed flexible sides that are configured to flex upon engagement with the frame and produce an audible click when the rotatable elbow has been securely attached to the frame. The rotatable elbow further includes a pair of diametrically opposed finger depressable release portions that are resiliently movable towards one another to allow release of the rotatable elbow from the frame.

Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a front surface and a rear surface adapted in use to face the patient. The frame includes a main body providing an aperture therethrough for the introduction of breathable gas into a nasal breathing cavity. An elbow assembly is swivelably coupled to the front surface of the frame. The elbow assembly includes a swivel elbow that defines an intake port and an exhaust port separated from the intake port using a baffle. The elbow assembly includes an end portion that interfaces with the aperture of the frame.

Abstract: A patient interface has a frame with an opening to receive pressurized gas; a cushion permanently co-molded to frame and defining a breathing chamber; an elbow assembly releasably snap-fittable to the frame with an audible click signaling secure attachment between the elbow assembly and the frame, the elbow assembly including a rotatable swivel elbow; headgear to support the patient interface on the patient's head; and a plurality of gas washout holes to allow escape of CO2 from the breathing chamber.

Abstract: A PAP system includes a PAP device to generate a supply of pressurized air, a patient interface adapted to form a seal with the patient's face, air delivery tubing to interconnect the patient interface and the PAP device, and a cover that substantially encloses at least a portion of the PAP device and a portion of the air delivery tubing. The cover allows the PAP device to be carried by and/or supported on the patient's head.
