Claim:
An infant nasal interface prong device for use with a continuous positive airway pressure (CPAP) system, the device comprising: first and second nasal prongs each including: a bellows segment, a tip extending from the bellows segment, the tip adapted for insertion within an infant's naris and terminating in a tip end opposite the bellows segment, the tip further including a tip body extending distal the tip end and wherein relative to an orientation upon insertion within the infant's naris, the tip body defines a top side and a bottom side, wherein at least a portion of the top side forms a convex curve and at least a portion of the bottom side forms a concave curve; a lumen extending through the prong and open at the tip end, wherein in an undeflected state, a central axis of the lumen as defined by the bellows segment is transversely offset from a central axis of the lumen as defined by the tip end; and a base connected to each of the nasal prongs and adapted for coupling to a CPAP generator, the base forming first and second passages fluidly connected to respective ones of the first and second lumens.
