Problems solved by technology

This in turn significantly affects the consistency of specific nostril diameters
Because the existing flexible nasal prong design cannot automatically correct for the actual nostril diameter encountered, it is necessary to have a relatively large number of different sized nasal prongs at hand
As can be expected, medical institutions are likely to prefer not to keep a large number of products in different sizes in stock; when

Embodiment Construction

[0021] exist figure 1 One embodiment of an infant nasal interface prong device for a continuous positive airway pressure (nCPAP) system 20 is shown in FIG. The interface device 20 includes a first prong 22 , a second prong 24 and a base plate 26 . Details about the individual components are provided below. In general, however, the prongs 22, 24 extend from the base plate 26 in a generally juxtaposed manner, each defining a lumen 28, 30 (generally designated) respectively. Substrate 26 is configured to create an nCPAP generator (in Figure 5A Shown at 150 in ) and the fluid connection between lumens 28,30. Accordingly, each of the first and second prongs 22, 24 is configured to be inserted within a patient's nostril. Furthermore, the prongs 22 , 24 are suitably highly flexible, allowing longitudinal movement and lateral / transverse pivoting relative to the base plate 26 without collapse of the respective lumens 28 , 30 . In this way, patient interface device 20 readily acco...

Abstract

An infant nasal interface prong device for use with an nCPAP system is disclosed. 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.

Description

technical field [0001] The present invention relates to patient nasal interface devices for use in continuous positive airway pressure (CPAP) systems. More particularly, the present invention relates to a nasal interface prong device for delivering CPAP therapy to the nasal airway of a patient, such as an infant. Background technique [0002] For many years, CPAP therapy has been used to treat patients experiencing dyspnea and / or respiratory failure. More recently, CPAP therapy has been modified to benefit patients with underdeveloped lungs (especially infants, especially premature infants or newborns) by preventing lung collapse during expiration and assisting lung inflation during inspiration . [0003] In general, CPAP therapy entails delivering continuous positive pressure to the lungs of a spontaneously breathing patient during the breathing cycle. A CPAP system generally includes a CPAP generator adapted to generate or generate a continuous positive airway pressure ...
