Claims25
A method for assembling a patient interface for treatment of sleep apnea by delivering breathable gas under pressure above ambient to at least one airway of a patient while sleeping, said patient interface including a substantially rigid frame defining a cavity with an opening, a silicone seal to seal with the patient's face, and a substantially rigid clip member, the method comprising:
- engaging the clip member with the silicone seal;
- and, thereafter,
- moving a resilient portion of the clip member to clip the clip member to the frame such that the clip member retains the seal in contact with the frame and such that the clip member is detachable from the frame.
A method for assembling a respiratory device for delivering breathable gas to a patient, said respiratory device comprising a frame having a first cooperating interlocking structure;
- a cushion provided to the frame;
- and a plastic cushion clip to retain the cushion on the frame, the cushion clip having a second cooperating interlocking structure and being selectively attachable to and detachable from the frame, the method comprising:
- engaging the cushion and the frame;
- interlocking the first cooperating interlocking structure and the second cooperating interlocking structure with one another in a cooperating relationship to secure the cushion clip on the frame, the first cooperating interlocking structure and the second cooperating interlocking structure are provided to at least two sides of the frame and the cushion clip and include a tab-recess arrangement in which a plurality of resiliently movable tabs are engageable within respective recesses in interlocking relation to clip the clip to the frame;
- and
- securing an elbow joint to the frame, said elbow joint having a swivel tube adapted to connect to a gas delivery conduit.
