An infant nasal interface prong device for use with an nCPAP system. The deviceincludes first and second nasal prongs and a base. Each prong includes a bellowssegment, a tip, and a lumen. The tip extends from the bellows segment to a tip endand is adapted for insertion with an infant's naris. The lumen extends throughthe tip and the bellows segment. In an undeflected state, a central axis of thelumen along the bellows segment is transversely offset from the lumen axis atthe tip end. The base is connected to each of the nasal prongs and is adapted forcoupling to a CPAP generator. The bellows segment renders the correspondingprong highly flexible relative to the base. The offset positioning of the tipend promotes desired positioning of the base/CPAP generator, relative to thepatient and more closely conforms to the expected nasal anatomy.
