Nasal interface apparatus
First Claim
1. A nasal interface for use in the nares of a patient for positive airway pressure applications comprising:
- a pair of nasal prongs, each prong having a bore, a first end, a second end, and at least one deformable flap disposed proximate to the first end of each prong;
a body having a distal portion and a proximal portion forming a chamber, the proximal portion having apertures to receive the second ends of the nasal prongs, the chamber being in communication with the bores of the nasal prongs;
at least one exhalation port within the body;
at least one gas inlet on the distal portion of the body, the at least one gas inlet in communication with the chamber;
wherein a substantially airtight seal is created within the nares of the patient.

Abstract
A nasal interface device for use in the nares of a patient for positive airway pressure applications includes a pair of nasal prongs, each prong having a bore, a first end, a second end, and at least one deformable flap disposed proximate to the first end of each prong. The device further includes a body having a distal portion and a proximal portion forming a chamber, the proximal portion having apertures to receive the second ends of the nasal prongs, the chamber being in communication with the bores of the nasal prongs, and at least one exhalation port disposed within the body. The device includes at least one gas inlet on the distal portion of the body, the at least one gas inlet in communication with the chamber. In one preferred aspect of the invention, the at least one flap is deformable within the nares of a patient thereby creating a substantially airtight seal.

19. A nasal interface for positive airway pressure applications comprising:
-
a pair of nasal prongs, each prong having a bore, a first end, a second end, and at least one flap disposed proximate to the first end of the prong;
a body having a distal portion and a proximal portion forming a chamber, the proximal portion having apertures to receive the second ends of the prongs, the nasal prongs being releasably engaged with the proximal portion, and wherein the chamber is in communication with the bores of the nasal prongs;
an exhalation port within the body that direct exhaled gas away from the chamber;
at least one gas inlet on the distal portion communicating with the chamber;
wherein one or more of the nasal prongs are rotatable within the apertures of the proximal portion of the body.
