Infant nasal interface prong device
First Claim
1. 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;
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.

Abstract
An infant nasal interface prong device for use with an nCPAP system. The device includes first and second nasal prongs and a base. Each prong includes a bellows segment, a tip, and a lumen. The tip extends from the bellows segment to a tip end and is adapted for insertion with an infant'"'"'s naris. The lumen extends through the tip and the bellows segment. In an undeflected state, a central axis of the lumen along the bellows segment is transversely offset from the lumen axis at the tip end. The base is connected to each of the nasal prongs and is adapted for coupling to a CPAP generator. The bellows segment renders the corresponding prong highly flexible relative to the base. The offset positioning of the tip end promotes desired positioning of the base/CPAP generator, relative to the patient and more closely conforms to the expected nasal anatomy.

19. An infant nasal continuous positive airway pressure (nCPAP) device for use in an nCPAP system, the device comprising:
-
an nCPAP generator including 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, 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 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. - View Dependent Claims (20, 21)

22. 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 including a tip body extending from the bellows segment and terminating at a tip end, the tip adapted for insertion within an infant'"'"'s naris, wherein the tip body defines a top side forming a convex curve and a bottom side forming 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 defined by the bellows segment is transversely offset from a central axis of the lumen 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;
wherein the first and second prongs extend in a juxtaposed fashion relative to the base, with the bellows segment of each of the prongs being non-symmetrical relative to an axis of the tip body.
