1. A nasal portion for a patient interface device of an airway pressure support system, the airway pressure support system comprising a gas flow generator, the gas flow generator being configured to generate a flow of breathing gas to be delivered to an airway of a patient, the patient interface device being in fluid communication with the gas flow generator in order to receive the flow of breathing gas generated by the gas flow generator, the nasal portion comprising:
an extension portion comprising a base configured to be in fluid communication with the gas flow generator, a conical end portion coupled to the base, and a first annular-shaped coupling portion disposed between the conical end portion and the base, wherein the conical end portion includes an exit opening defined in a distal end of the conical end portion, a first side opening defined on a first side of the conical end portion, and a second side opening defined on a second side of the conical end portion opposite the first side of the conical end portion, wherein the first side opening and the second side opening in the conical end portion are generally aligned along a first axis; and
a conical shaped cap member defining an exit opening and being provided on the extension portion such that conical end portion of the extension portion extends into an interior of the cap member and such that the exit opening is coaxially aligned with the exit opening of the extension portion, wherein the cap member includes a second annular-shaped coupling portion adapted to engage the first annular-shaped coupling portion, wherein the cap member includes a first side opening defined on a first side of the cap member and a second side opening defined on a second side of the cap member opposite the first side of the cap member, wherein the first side opening and the second side opening of the cap member are generally aligned along a second axis, wherein the first axis and the second axis are perpendicular to one another.
