A nasal assembly for delivering breathable gas to a patient includes a frame having lateral connector, a cushion with a pair of nozzles, and a clip to secure the cushion to the frame. The frame includes a vent channel and a plurality of vent holes. The frame/cushion includes structure (lugs/cut outs) to prevent the assembly of an unvented frame with an unvented cushion, for safety purposes. The frame includes cored portions that interface with corner lugs provided on the cushion. A patient interface includes a frame, a cushion (nasal mask, nasal-oro mask, nozzles, etc.) and a vent assembly including a pattern of vent holes including at least two rows.

Mask with vent columns

Nasal assembly

A nasal or full-face mask frame includes a main body and a vent assembly provided to the main body. The vent assembly includes a plurality of holes arranged in at least one column. The holes are positioned on a relatively flat and/or non-recessed portion of the main body.

Frame and vent assembly for mask assembly

A washout vent for a mask for use with a system for supplying breathable gas pressurized above atmospheric pressure to an airway of a mammal for treatment of sleep disordered breathing, includes a solid mask section and a vent orifice extending through a thickness of the solid mask section and adapted for gas washout. The vent orifice includes opposed side walls providing a flow passage that allows gas to flow along the opposed side walls from an interior of the mask to atmosphere in use, and the opposed side walls defining at least a portion of a conic section having a length substantially greater than its width. The vent orifice includes an orifice inlet at the interior of the mask and an orifice exit open to atmosphere, and the opposed side walls converge from the orifice inlet to the orifice exit to reduce noise of gas washout.

Respiratory mask having gas washout vent and method for making the mask

A comfortable low-leak mask assembly for use with Non-Invasive Positive Pressure Ventilation (NIPPV) is provided to improve patient compliance and/or treatment. The mask system may include headgear having straps that are substantially inextensible and/or micro-adjustable; and/or a mask and/or cushion that includes various structures to allow enhanced/tailored sealing and/or fit at selected locations on the patient's face.

Mask and components thereof

Mask system includes frame, cushion, cushion clip, swivel elbow, headgear and/or headgear clips configured for use in a clinical or hospital environment. One or more components of the mask system configured to promote single patient use, for example, by providing an age indicator and/or preventing disassembly and/or cleaning.

Mask system

A ports cap for a mask assembly includes two closure portions adapted to seal respective ports of the mask assembly, a bridge piece that joins the two closure portions, and two gripping tabs extending outwardly from respective closure portions. Each gripping tab includes one or more ribs on at least one side thereof.

Ports cap for mask assembly

An elbow assembly for a mask assembly includes an anti-asphyxia valve (AAV) assembly that may take the form of a box-like frame work, a drop-in arrangement, or a slot-in arrangement. In each case, the AAV assembly may include a flap element which is movable so as to either direct ambient gas/air to the elbow assembly and thus the patient using the mask assembly, or to allow the passage of pressurized gas to the patient.

Anti-asphyxia valve assembly for respirator mask

Frame for respiratory mask

Respiratory mask

A washout vent for a mask for use with a system for supplying breathable gas pressurized above atmospheric pressure to an airway of a mammal. The washout vent includes a vent orifice adapted for gas washout. The orifice includes one or more features that contribute to noise reduction, such as a channel with converging walls towards atmosphere, and/or a channel having one or more walls provided with surface treatment and/or contouring, such as roughening and/or scalloped portions.

A forehead support for a mask assembly includes a frame connector provided to a mask frame, a forehead cushion support movably mounted to the frame connector for generally linear movement between retracted and extended positions with respect to the frame connector, and an adjustment knob movably mounted to the frame connector and threadably engaged with the forehead cushion support such that turning movement of the adjustment knob causes the forehead cushion support to be moved between the retracted and extended positions. The adjustment knob includes a resilient prong having a ratchet bump. The ratchet bump is adapted to selectively engage a series of ridges provided to the frame connector to provide indexed incremental adjustment.
