Infant nasal interface prong device

An infant nasal continuous positive airway pressure (nCPAP) device for use in an nCPAP system, the device comprising:

• an nCPAP generator including a housing laterally surrounding first and second tubes, the nCPAP generator adapted to generate a continuous positive airway pressure within each of the tubes;
• and
• an infant nasal interface prong device mounted to the tubes, the infant nasal interface prong device comprising:
• first and second nasal prongs each including:
• a bellows segment,
• a tip extending from a bellows segment, the tip adapted for insertion within an infant's naris and terminating in a tip end opposite the bellows segment, wherein the tip includes a tip body extending distal the tip end. and further wherein relative to an orientation upon insertion within an infant's naris. the tip body defines a top side and a bottom side, and further 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 distal 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 defined by the tip end, and
• a base sized to be received by the housing, the base being connected to each of the nasal prongs and forming first and second passages fluidly connected to respective ones of the first and second lumens, wherein the passages are fluidly connected to respective ones of the first and second tubes upon final assembly;
• wherein the base and the housing define corresponding, non-symmetrical perimeter shapes.
