A nasal cannula diffuses a gas stream to distribute the volume of the gas stream as it is delivered into a user's nostril. The nasal cannula can direct flow of gas, such as oxygen, away from the more sensitive nasal tissues. The nasal cannula can diffuse the gas flow out of a plurality of orifices formed in the nostril prongs of the nasal cannula device, rather than sending the entire volume of gas out of a single orifice, as is the case with conventional nasal cannula devices.

An apparatus and method for preparing saline solution and using the saline solution for rinsing nasal passages. The apparatus includes a container (10) having sidewalls and opening for a removable cap (13). The cap has an external tapering hollow nozzle (14). The nozzle (14) is inserted into one end of a flexible tube (21). The other end of the tube (21) is inserted into a hollow removable contoured dispenser tip (23) which is shaped to fit a human nostril comfortably. A thin tubular conduit (19) is attached to the cap by means of a fitting (16) and the conduit extends into the container (10) close to its bottom when the apparatus is fully assembled. A saline solution is prepared by adding iodine free common salt to warm distilled or boiled water in the container. After attaching the cap (13) to the container (10) and inserting the dispenser tip (23) into one nostril, a user bends forward and tilts the head to the side of the other nostril and breaths through open mouth. The user then allows the saline solution to flow by gravity through one nostril and come out through the other open nostril, after passing through nasal passages, by holding the container (10) inverted (bottom up cap down) and raising it above the level of nostrils. The rate of flow of the saline solution to the nostril can be controlled by varying the height at which the container is held above the level of nostrils.

The invention is an apparatus that blocks out light and improves breathing. The apparatus includes a sleep mask with an integral nasal dilation system. The nasal dilation system includes a nasal element mounted with on the nose section of the mask, where the nasal element in one version has a channel through which a band can move substantially orthogonal to the wearer's nose. Sidewalls center the band, and inward folded cuffs retain the band. The band encircles the wearer's head between the mask straps. It is threaded through the slideway and can slide therein equalizing side-to-side forces. The band is elastic and when stretched it generates an opposing force. Pressure is exerted on the nose by using the band in a stretched state. The extended band creates pressure on the slideway, which causes the nose section to press against the nostrils causing them to distend, which in turn dilates the nasal passages, and breathing is improved.

An improved, preferably plastic, universal breathing aid device for insertion into the nasal passages having a first pair of septum-engaging and gripping arms, from which are cantilevered a pair of curved, spring-action nostril-expanding arm that keep the nasal passages open. The septum-engaging arms are supported by a base member in the form of an open loop that includes a living hinge to provide flexibility and accommodation to varying sizes of nasal septums. The flexibility of both sets of arms promotes user comfort. The living hinge urges the septum arms together to provide grip yet comfort via the flexibility of the hinge. The nostril-expanding arms act in the opposite direction, opening the airway. The contours of the arm and tip cross sections may be varied for comfort, and device may range from generally planar to three-dimensional. The inventive device is unobtrusive and easily kept sanitary.

An inconspicuous nasal-dilating device for a constricted nostril, the device being insertable into and frictionally retained in the constricted nostril. The device has a circular cross-sectional shape that is laterally squeezable to an oval shape for purposes of inserting the device into the constricted nostril and, upon being released from the oval shape, attempts to return to its circular cross-sectional shape thereby dilating an air passageway of the constricted nostril.

A device for relieving congestion in restricted nasal passages, by the dilation thereof with an internal prosthesis placed within the nasal passages of an individual. This prosthesis comprises an adjustable bow having a pair of appendages extending from each end thereof. A separate tensioning element engages complimentary features on / in the bow to limit flexure thereof, and thereby provide a counterforce to bending of the bow. Accordingly, when the bow is flexed or bent, the extent of flex or bending of the bow is constrained by the tensioning element. The combined effect of the natural recoil of the resilient bow from the distended to flat position, combined with the counter forces imparted to the bow by the tensioning element, causes each appendage on the end of the bow to exert a constant pressure within each nasal passage to maintain such passages in a relatively open position.

A nasal breathing aid includes a base portion and two extending diverging arms. The arms, near their base include inward facing contact elements which are adapted to “pinch” the vomer bone within the nose. The arms, at their outer ends, include outward facing contact elements which are adapted to apply pressure to the inner wall of the nostrils, urging a wider passageway through the nostrils.

A nasal interface uses asymmetrical nasal delivery elements to deliver an asymmetrical flow through the interface to both nares or to either nare, and a mouthpiece may be inserted to maintain a leak, to improve dead space clearance in the upper airways, decrease peak expiratory pressure, reduce noise, increase safety of the therapy for smaller patients and reduce resistance in the interface allowing desired flow rates to be achieved at reduced motor speeds of associated flow generating devices. Different forms of fittings, such as sleeves or inserts can be attached to nasal delivery elements to improve or optimise the therapeutic effects of nasal high flow. It may allow high pressures to be achieved at lower flow rates, reduce noise, improve patient comfort and efficiently clear anatomical dead space.
