A nasal interface device (20) comprising:
first and second nasal prongs (22,24); and
a base (26) connected to each of first and second nasal prongs (22, 24) by means of a first passage (72) and a second passage (74) respectively, each defining a passage axis (P),
the first and second nasal prongs (22,24) each including:
a bellows segment (42),
a tip (40) having a tip body (48) extending from the bellows segment (42) and terminating in a tip end (46) opposite the bellows segment,
a foot (44) extending from the base (26) to the bellows segment (42); and
a lumen (28, 30) extending through the prong and open at the tip end,
wherein in an undeflected state, a central axis (Abellows) of the lumen as defined by the bellows segment (42) is transversely offset from a central axis (Atip) of the lumen as defined by the tip end (46), and, relative to the passage axis (P), a central axis (Afoot) of the foot (44) projects laterally outwardly with proximal extension of the foot (44) from the base (26). |
