A nasal mask assembly for nasal CPAP therapy, comprising: a mask frame; a silicone nasal seal which can be repeatedly detached from and reattached to the frame; an elbow rotatably coupled to the frame and adapted to connect to a gas delivery tube; and a headgear assembly to secure the frame and nasal seal to a patient's head. The headgear assembly includes a pair of relatively flexible, Y-shaped straps (84) having a relatively soft fabric and foam material construction, and a stiffening support structure (92) made of a relatively rigid material compared to the strap material. The stiffening support structure is attached to an outside surface of a portion of the pair of straps resting against the cheek regions in use. Mounting means (100) integral with the stiffening support structure is provided to detachably mount the headgear assembly relative to the frame. |
