Nasal appliance

Abstract: A device for enabling a person to breathe more easily while alleviating snoring problems. The device (10) is a generally W-shaped frame (20) providing a pair of suitably sized spacing tips (12) for insertion into the user's nostrils. These tips serve to open and shape the nasal passages so that breathing is facilitated.

Description: This invention relates to devices used to improve breathing through a person's nasal passageways and, more particularly, to devices used to alleviate snoring and ease breathing. In brief, particular arrangements in accordance with the present invention include a specially shaped frame having a pair of spacing tips adapted for insertion into the nasal fossa to expand the breathing passages when the device is in use. Each spacing tip covers the free end of a corresponding strut provided at an associated frame end such that the tipped struts can be inserted into, and maintain their position within, the nostrils of the user. The present invention improves the flow of air through the nose through a stenting, i.e. preventing collapse, of the cartilages of the nose on inspiration. The mechanism of action may be more easily understood with the following conceptual model. Imagine the anatomy of the nose as a simple tent open at both ends. However, instead of tent poles holding up the tent, a wall-like partition exists between the two sides. This wall is the nasal septum, dividing the two nostrils, and the sides of the tent represent the cartilages of the nostrils. In a normal nose, air flows smoothly through the two sides of the tent as breathing occurs. As inhalation effort increases, so does the likelihood of collapse of the sides of the nose due to the venturi effect. Referring to our tent model, the apex of the tent, i.e. the area where the sides come together with the wall at the top of the tent, exerts the most critical influence on air flow. In the nose, the portion of the apex near the front of the nose forms the upper part of what is referred to as the nasal valve. The present invention acts at this area, serving to prevent collapse of the nostrils when air is inspired. Even in a normal nose, collapse of the nostrils will occur as air flow speed is increased. In persons with distorted nasal anatomy, the effects are far worse. If a person has a deviated septum, which may be thought of as a "warped" wall of the tent, increased effort is required to move the same volume of air through the nasal valve. This increased effort may manifest itself as snoring. Finally, if the sides of the tent are narrowed at the top, as is commonly seen after cosmetic surgery to narrow the tip of the nose, the same effects are noted; i.e. increased effort is required to pass a given volume of air through a narrowed passageway. WO-A-96/01093 describes a resilient band which tends to force wall tissues in the human body away from each other. US 5479944 discloses two tabs joined by a connecting member which is formed of a resilient material. Upon bending the connecting member, each tab may be placed in a respective nostril where they will be biased outwardly against the nasal sides to open the nostrils. US 2515756 is considered as representing the closest prior art. The present invention is concerned with the appliance defined in claim 1. The appliance of the present invention serves to prevent collapse of the sides of the nose from the venturi effect as described above. The present invention maintains patency of the apex of the nasal valve during inspiration through the stenting of the cartilages of the nose by the placement of the spacing tips at the apex of the nasal valve which thereby form stents. The appliance comprises a generally double U-shaped frame terminating in a pair of spacing tips forming the stents. The device is dimensioned and shaped so that the spacing tips may be inserted into the outer ends of one's nasal passages (the nasal fossa). The frame is preferably fabricated of a spring material exhibiting a degree of malleability, such as copper or stainless steel or a suitable plastic, rubber, silicone or the like, so that the device can be easily fitted to an individual user. The spacing tips may be enlarged attachments placed over the ends of a pair of intra-nasal struts which form the ends of the frame that is bent and shaped to bridge the nostrils. Preferably, each spacing tip is made of a hypo-allergenic, non-irritating, cushioning material such as surgical-grade silicone. If the frame is fabricated of a suitable material, the entire unit, including the spacing tips, may be integrally formed as one. In the accompanying drawings: FIG. 1 is a perspective view of one arrangement of the present invention and identifies some of the approximate dimensions of one particular embodiment of the device; FIG. 2 is a detailed schematic view of one of the spacing tips of the arrangement of FIG. 1, again identifying some of the approximate dimensions of the embodiment of FIG. 1; FIG. 3 is an elevated side view of the arrangement of FIG. 1; FIG. 4 is an end view of the arrangement of FIG. 1, looking from the right side of the figure; FIG. 5 is a top view of the arrangement of FIG. 1, again identifying some of the approximate dimensions of the device of FIG. 1; FIG. 6 is a partial view of one part of the device in place, showing the increased cross-sectional area that is achieved through the use of the device (left nasal passageway) in comparison with the shape of the nasal passageway without the device (right nasal passageway); and FIG. 7 is a side view showing the device as it would be inserted by a user. FIG. 1 shows a device 10 embodying the present invention. The device 10 eases breathing and enlarges the nasal passageways by properly positioning each of a pair of spacing tips 12 , shown in FIG. 1, within the nasal fossa. In the FIG. 1 embodiment each spacing tip 12 measures approximately 3/8" in diameter and approximately 1/2" in length. In order to fit a wide variety of noses, several sizes of the present invention may be offered. The spacing tips 12 may vary from 1/16" to 3/8" in diameter and may vary from 1/16" to 1/2" in length. For comfort and cleanliness, each spacing tip 12 is made of a hypo-allergenic, nonirritating, cushioning material, such as surgical grade silicone. If desired, the spacing tips 12 may be formed of latex rubber, polyurethane or ordinary plastic. The spacing tips 12 could even be formed of metal, if shaped and given a smooth outer surface which would not cause the user discomfort. An added possibility is that the spacing tips 12 might be fabricated in the form of fluid-filled flexible membranes, as indicated in FIG. 5, for example, for more readily conforming to the interior surfaces of a user's nostrils. The present invention provides for the repeated accurate and proper placement of the spacing tips 12 through their arrangement at each end of a frame 20 . The frame 20 is formed of a material having some spring properties yet retaining a degree of malleability and is configured to resemble a series of compound curves, as seen in elevated side view FIG. 3, top view FIG. 4, and front view FIG. 5. FIG. 3 shows the spacing tips 12 covering the free ends of a pair of intra-nasal struts 21 . The intra-nasal struts 21 are formed adjacent a pair of generally U-shaped nasal curves 22 . The opposing ends of the nasal curves 22 are formed adjacent the ends of a pair of extra-nasal struts 23 . The opposing ends of the extra-nasal struts 23 connect to a pair of saddle curves 24 . A saddle 25 extends between, and connects, the saddle curves 24 . For additional user comfort, the saddle 25 may be outfitted with a saddle pad 26 , positioned over the saddle 25 , to cushion the bridge of the user's nose from contact with the saddle 25 . The saddle 25 may be provided with an adhesive surface 28 , if desired, in order to assist in providing secure positioning of the nasal appliance in place for use. The adhesive surface 28 may be formed integrally with the saddle 25 or, alternatively, it may be disposed upon the saddle after forming thereof. In still another version, the adhesive surface 28 may be applied to the frame by the user. In another version, an adhesive surface 29 may be affixed to the saddle pad 26 , rather than to the saddle 25 . In one particular preferred embodiment, as indicated in FIGS. 1, 2 and 3, the spacing tips 12 have an outer diameter of 3/8" and a length of 1/2". The transverse dimension (width) of the saddle 25 is approximately 1/2" with the spacing between the nasal curves 22 being approximately 3/8". The overall dimension of the frame from the saddle pad 26 to the nasal curves 22 is approximately 3/4" whereas the overall dimension from a nasal curve 22 to the end of an associated spacing tip is approximately 1". The distance between spacing tips is approximately 1/4". These dimensions may vary proportionally for the variety of sizes of the device 10 provided to accommodate different users. In use of the device 10 , the spacing tips 12 and intra-nasal struts 21 are carefully inserted into the user's nasal fossa (nostrils). The device is gently elevated into the nasal fossa until resistance is felt. The user would then depress the saddle 25 and saddle pad 26 onto the nasal dorsum while stabilizing the intra-nasal struts 21 with his thumbs. Customizing the fit of the device may be realized by slightly bending the malleable frame 20 , specifically at the nasal curves 22 and the saddle curves 24 . When used in this fashion, after perhaps a slight initial adjustment, the device provides increased ease of breathing and relief from snoring without any discomfort. Additionally, the user will be able to achieve the same successful results time and again, due to the capability of the device to be cleaned by washing with soap and water, after which it is ready for re-use. Side view FIG. 7 shows the device 10 being inserted, adjusted and worn by the user. Device 10 is available in a variety of sizes (e.g. small, medium, large) to accommodate all users.
