The present invention is related a nasal positive airway pressure device. The nasal device utilizes an engagement means located about nasal cannulae to engage and secure the cannulae within the nares of a patient. The engagement means is a nasal scaling flap. The flap in its natural bias is tapered, the wide-open end of which is shaped to conform to the facial contours of a patient's nose around the outside of the nose. Thus in a closed form, the flap provides a cup-like device that is fitted around the patient's nose and prevent the nasal device from falling from the patients nose. In the open form, which allows for placement and fitting of the nasal device, the flap is intended to be in a bent back position to aid insertion of the nasal cannulae into the patient's nares.

We claim: 1. A device for use as part of a system for delivering a supply of gases to a patient comprising: a nasal member in fluid communication with a pair of nasal cannulae, said nasal member adapted to receive breathing gases and direct said gases to said nasal cannulae, a securing flap arranged about said nasal cannulae and adjustable between a first biased position and a second biased position, in said first biased position, said flap is arranged in an open curve adjusted away from said nasal cannulae, permitting said nasal cannulae to be inserted or removed from the nares of said patient, in said second biased position, said flap conforms to a cup-like shape, substantially conforming to, and engaging with the bridge of said patient's nose, said engagement providing a compressive force about said patient's nose and securing said nasal cannulae in the nares of said patient. 2. A device according to claim 1 wherein one end of said nasal member is adapted to connect to a flexible conduit. 3. A device according to claim 2 wherein said nasal member is a tubular member defining a further passage for the flow of gases from said flexible conduit to the nares of said patient. 4. A device according to claim 1 wherein said nasal member is integrally formed with said flap. 5. A device according to claim 4 wherein said nasal cannulae are also formed integrally with said flap. 6. A device as claimed in any one of claims 1, 2, 3, 4 and 5 wherein in said first biased position said securing flap is arranged in an open configuration with peripheral portions of said securing flap deflected outwardly, the open configuration permitting the nasal cannulae to be inserted within and removed from the nares of the patient without said securing flap interfering with the patient's nose, and in said second biased position said securing flap is arranged in a closed configuration with said peripheral portions deflected inwardly, said securing flap substantially conforming to the bridge of the patient's nose in the closed configuration and providing said compressive force. 7. A device as claimed in claim 6 wherein said securing flap will remain in either said first or second biased position unaided, said securing flap elastically adjustable between said first and second biased positions, substantial movement of said securing flap from said first biased position toward said second biased position causing the securing flap to bias to the second biased position and assume a predefined shape, said securing flap is adjusted between said biased positions by applying a force to peripheral portions of the securing flap in a direction of the desired biased position, said securing flap moving through a transition region between the first and second biased positions, the securing flap biasing to the second biased position after moving past the transition region. 8. A device as claimed in claim 7 wherein said securing flap is arranged around said nasal cannulae, the open configuration permitting the nasal cannulae to be inserted within and removed from a patient's nares, the closed configuration conforming to an exterior contour of a patient's nose and providing said compressive force. 9. A device for use as part of a system for delivering a supply of gases to a patient comprising: a nasal member in fluid communication with a pair of nasal cannulae, said nasal member adapted to receive breathing gases and direct said gases to said nasal cannulae, a securing flap arranged about said nasal cannulae and adjustable between a first biased position and a second biased position, said securing flap being adjusted between said first and second biased positions by applying a forced to peripheral portions of the securing flap in a direction of the desired biased position, said securing flap remaining in said first biased position and said second biased position unaided, in said first biased position said securing flap is arranged in an open configuration, with peripheral portions of said securing flap deflected outwardly in an open curve away from said nasal cannulae to permit said nasal cannulae to be inserted or removed from the nares of said patient, in said second biased position said flap is arranged in a closed configuration with said peripheral portions deflected inwardly to form a cup-like shape so that said flap substantially conforms to, and engages with, the bridge of said patient's nose, said engagement providing a compressive force about said patient's nose that secures said nasal cannulae in the nares of said patient, wherein said securing flap is elastically adjustable between said first and second biased positions, substantial movement of said securing flap from said first biased position toward said second biased position causing the securing flap to pass through a transition region and bias to the second biased position and assume a predefined shape. 10. A device for use as part of a system for delivering a supply of gases to a patient comprising: a nasal member in fluid communication with a pair of nasal cannulae, said nasal member adapted to receive breathing gases and direct said gases to said nasal cannulae, a securing flap arranged about said nasal cannulae and adjustable between a first biased position and a second biased position, in said first biased position, said flap adjusted away from said nasal cannulae, permitting said nasal cannulae to be inserted or removed from the nares of said patient, in said second biased position, said flap substantially conforming to, and engaging with the bridge of said patient's nose, said engagement providing a compressive force about said patient's nose and securing said nasal cannulae in the nares of said patient, wherein in said first biased position said securing flap is arranged in an open configuration with peripheral portions of said securing flap deflected outwardly, the open configuration permitting the nasal cannulae to be inserted within and removed from the nares of the patient without said securing flap interfering with the patient's nose, in said second biased position said securing flap is arranged in a closed configuration with said peripheral portions deflected inwardly, said securing flap substantially conforming to the bridge of the patient's nose in the closed configuration and providing said compressive force, wherein said securing flap will remain in said first biased position and said second biased position unaided, said securing flap elastically adjustable between said first and second biased positions, substantial movement of said securing flap from said first biased position toward said second biased position causing the securing flap to bias to the second biased position and assume a predefined shape, said securing flap is adjusted between said biased positions by applying a forced to peripheral portions of the securing flap in a direction of the desired biased position, said securing flap moving through a transition region between the first and second biased positions, the securing flap biasing to the second biased position after moving past the transition region, and wherein in the first biased position the securing flap is arranged in an open curve, and in the second biased position the securing flap conforms to a cup-like shape.
