Description
FIELD OF THE INVENTION

[0001] The present invention relates generally to an anti-snoring device for insertion into a user's mouth for providing an unobstructed buccopharyngeal pathway for inspiratory and expiratory airflow to prevent snoring, sleep disordered breathing and/or obstructive sleep apnea.

BACKGROUND

[0002] Sleep Apnea is a common disorder affecting approximately 20,000,000 Americans. Sleep Apnea refers to a cessation of breathing during sleep that lasts at least 10 seconds. Snoring is another common sleep disorder. By conservative estimates, approximately 80,000,000 Americans are afflicted with snoring.

[0003] These sleep disorders cause countless hours of lost sleep and productivity for the afflicted persons, as well as their sleeping partners. In addition, Sleep Apnea is highly associated (50%) with essential hypertension, obesity and heart disease. Moreover, extreme cases of Sleep Apnea can be life threatening.

[0004] Current therapy includes sleep position modification, weight loss, and/or lifestyle changes such as the elimination of alcohol, drug use and/or over-eating. Other therapies include the use of mechanical devices such as oral or nasal devices that augment the airway, surgical procedures to enlarge and stabilize the airway during sleep, and continuous positive airway pressure devices.

[0005] Nasal devices that dilate the anterior nares by external traction or internal splinting have been used with minimal success. Nasal intubation is poorly tolerated and traumatic to the user.

[0006] Current oral devices are typically of two types. One type of oral device involves a tongue retention device that advances and secures the tongue using suction, or mechanical tongue depression and stabilization. However, this type of oral device has limited success and is poorly tolerated by the user. A second type of oral device is a mandibular repositioning device that advances the lower jaw relative to the fixed upper jaw to expand the cross-sectional area of the pharynx thereby improving airflow and preventing collapse. These devices have been variably effective, but commonly have both comfort and compliance problems.

[0007] Surgical treatments are varied and include reconstruction of the palate and uvula, various methods to shrink and stiffen the soft tissue of the upper airway, tonsillectomy, laser treatment, radio frequency tissue reduction, hyoid suspension, and tongue base excision and retention. More radical surgical treatments for severe disorders include tracheotomy and surgical advancement of the upper and lower jaws. Surgical treatments are typically highly expensive, painful, complicated and have varying success rates (typically 40-60%).

[0008] Nasal and/or oral continuous positive airway pressure has been the most successful of the current sleep disorder treatments. However, this treatment is highly expensive and poorly tolerated by many user's who typically find the treatment intrusive and intolerable. Accordingly, a need exists for an effective, well tolerated, economical treatment for persons afflicted with sleep disordered breathing.

SUMMARY

[0009] In one embodiment, the present invention is an anti-snoring device that includes a flexible hollow tube for insertion into a user's mouth, having proximal and distal ends and an outer perimeter. The tube includes an extraoral segment at its proximal end, an intraoral segment at its distal end and an intermediate segment extending therebetween. The extraoral and intraoral segments each include at least one opening. The extraoral segment is for extending beyond the user's outer lips, the intermediate segment is of sufficient length for extending along the buccopharyngeal pathway of the user's mouth, and the intraoral segment is of sufficient length for extending beyond a retromolar space in the user's mouth, into the oropharynx and terminating between the posterior tongue and the soft palate. The anti-snoring device also includes a stop extending from the outer perimeter of the tube on the intraoral segment for securing the intraoral segment within the user's oropharynx.

[0010] Another embodiment of the present invention includes a method of reducing snoring in a user's mouth. The method includes inserting into the user's mouth a flexible hollow tube that has an extraoral segment at its proximal end, an intraoral segment at its distal end and an intermediate segment extending therebetween, wherein the extraoral and intraoral segments each include at least one opening. The method further includes positioning the extraoral segment of the tube exterior to the user's lips, positioning the intermediate segment of the tube along the buccopharyngeal pathway of the user's mouth and positioning the intraoral segment of the tube beyond a retromolar space in the user's mouth, into the oropharynx and terminating between the posterior tongue and the soft palate.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0023] As shown in FIGS. 1A-5, an embodiment of the present invention is an anti-snoring device for insertion into a user's mouth for providing an unobstructed buccopharyngeal pathway for inspiratory and expiratory airflow to prevent snoring, sleep disordered breathing and/or obstructive sleep apnea. Snoring is a common benign condition characterized by noisy harsh breathing during sleep resulting from soft tissue airway collapse and vibration during the respiratory cycle. This creates a dynamic vibratory resonance between the pressure of respiratory effort and the inherent elastic recoil of the soft tissues.

[0024] In the embodiments of FIGS. 1A-5, the anti-snoring device 10 includes a flexible hollow tube 8 having three segments, an extraoral segment 14, an intermediate segment 16, and an intraoral segment 18. The extraoral 14 and intraoral 18 segments each include at least one opening. For example, in the depicted embodiment, the extraoral segment 14 includes an open end 20 and the intraoral segment 18 includes an open end 21.

[0025] As shown in FIG. 3, when the anti-snoring device 10 is inserted into a user's mouth 25 a buccopharyngeal pathway 11 is created for inspiratory and expiratory airflow as illustrated by arrows 22. The buccopharyngeal pathway 11, as used herein, is defined as a pathway extending along an outer surface 28 of the of the user's dentition, between the outer surface 28 of the user's dentition and an inner surface 26 of the user's inner cheek, wherein dentition is defined as the user's teeth and gums in the user's dental arch.

[0026] When the anti-snoring device 10 is positioned as shown, the intraoral segment 18 extends past a retromolar space 27 (defined as an area in the user's upper or lower dentition past the user's last molar or an area past the user's upper and lower dentitions when the user's mouth is closed), enters the oropharynx 30 (defined as the posterior oral cavity behind the user's dentition) and terminates between the posterior tongue and the soft palate. The retromolar space 27 as defined herein is created by the removal or nonexistence of at least the upper and/or lower third molar in the user's mouth 25.

[0027] In the depicted embodiment, the user's mouth contains a first upper molar 31 and a second upper molar 32, but does not contain a third upper molar. The absence of the third upper molar allows the anti-snoring device 10 to cross behind the user's dentition and enter the user's oropharynx 30. Although, the upper teeth are depicted, a depiction of the lower teeth would be substantially similar and is not included herein to avoid duplicity.

[0028] Adjacent to the intraoral segment 18 is the intermediate segment 16. The intermediate segment 16 extends along the buccopharyngeal pathway 11. The intermediate segment 16 may be positioned adjacent to the user's upper dentition, lower dentition or both the upper and lower dentitions, and may pass through the retromolar space 27 in the user's upper dentition, lower dentition or both the upper and lower dentitions, as long as the intermediate segment 16 passes along the buccopharyngeal pathway 11 and the intraoral segment 18 enters the oropharynx 30. The extraoral segment 14 is adjacent to the intermediate segment 16. The extraoral segment 14 extends past the user's lips 34 and outside the user's mouth 25.

[0029] When the anti-snoring device 10 is positioned as described above, the unique buccopharyngeal pathway 11 is created as depicted by arrows 22 for inspiratory and expiratory airflow during sleep. The buccopharyngeal pathway 11 is unique because it utilizes a route of airflow that is typically not used in normal breathing patterns and is not previously described in the medical literature as a route for respiratory airflow. The buccopharyngeal pathway 11 presents a pathway for airflow during normal breathing patterns only when it is “stented” open by the anti-snoring device 10 as described above. The anti-snoring device 10 also allows for the buccopharyngeal pathway 11 to be stented open even with the user's mouth closed and allows the user's dentition to remain in its natural and normal position, while accommodating normal jaw movement. As a result, normal swallowing, throat clearing, yawning, coughing and sneezing are not disturbed when the anti-snoring device 10 is in the user's mouth. In addition, since the intraoral segment 18 is positioned in the posterior oropharynx 30 and terminates on the lateral-posterior tongue the naturally triggered gag reflex is markedly diminished.

[0030] The anti-snoring device 10 eliminates snoring, sleep disordered breathing and obstructive sleep apnea for several reasons. For example, the intraoral segment 18 “stents” open or separates the posterior tongue and the soft tissue of the soft palate, which tend to collapse and vibrate during sleep to create the sound of snoring. The anti-snoring device 10 also allows free flow of air to the posterior oral cavity at a markedly reduced resistance which allows for a decreased vacuum (negative) pressure of inspiration and a reduced pulsion (positive) pressure of expiration.

[0031] The anti-snoring device 10 also contains a flexible outwardly extending stop 13 that forms a portion of the intraoral segment 18. In one embodiment, the stop 13 extends annularly about the tube 8. In another embodiment, the stop 13 extends from the outside diameter of the tube 8, but does not extend annularly about the tube 8. The stop 13 serves to secure the anti-snoring device 10 against anterior displacement, and secures the intraoral segment 18 within the oropharynx 30 of the user's mouth 25. The stop 13 is larger than the retromolar space 27 and therefore prevents retraction therethrough. The stop 13 frictionally secures the intraoral segment 18 within the oropharynx 30 by abutting the last tooth in the retromolar space 27, which in the depicted embodiment is the second molar 32, and/or the portions of the jaw bone and/or gums that surround the retromolar space 27.

[0032] The stop 13 may be adjustable along the length of the tube 8, for example, by being slidably mounted on the outside diameter 42 of the tube 8. For example, in the embodiments shown in FIGS. 1-3, the stop 13 is a sleeve, that has an inner opening 52 that is slightly smaller than or approximately equal to the outside diameter 42 of the tube 8. As a result, the stop 13 is frictionally secured to the tube 8, but can be adjusted by the user along the outside diameter 42 of the tube 8 by the application of an appropriate force. The adjustability of the stop 13 allows the anti-snoring device 10 to conform to the user's particular anatomy and allows the user to vary the length of the tube 8 that enters the oropharynx 30.

[0033] The stop 13 may have any shape and size as long as it comfortably fits within the oropharynx 30 of the user's mouth and secures the intraoral segment 18 within the oropharynx 30 of the user's mouth 25. For example, in the embodiments shown in FIGS. 1-3, the stop 13 is a sleeve having concentric circular outside and inside surfaces, wherein the outside diameter d is approximately 28 French (Fr) to approximately 38 Fr, the inside diameter id is approximately 26 Fr to approximately 36 Fr, the length l is approximately {fraction (3/16)} inch to approximately {fraction (1/2)} inch and the thickness t is approximately 0.3 Fr to approximately 2.5 Fr, wherein 1 French is a unit of measure equal to 3.01 millimeters.

[0034] In one embodiment, the stop 13 has an outer diameter d of approximately 30 Fr, an inside diameter id of approximately 28 Fr, a length l of approximately {fraction (1/4)} inch, a thickness t of approximately 1.0 Fr and the tube 8 has an outside diameter 42 of approximately 28 Fr.

[0035] In the embodiments of FIGS. 1C-1D and 2B-3, the anti-snoring device 10 also contains a thin flexible retention diaphragm 12 that forms a portion of the intermediate segment 16. The retention diaphragm 12 contains a first side 38 that, due to its flexibility, conforms to the user's inner lips and/or inner cheek and a second side 40 that conforms to an outer surface of the user's teeth. The retention diaphragm 12 secures the intermediate segment 16 within the user's buccopharyngeal pathway 11 and prevents anterior displacement of the anti-snoring device 10. The retention diaphragm 12 also acts as a saliva dam to prevent drooling of naturally occurring saliva developed during sleep.

[0036] The retention diaphragm 12 is adjustable, for example, by being slidably mounted to the outside diameter 42 of the tube 8. For example in one embodiment, the retention diaphragm 12 includes an opening 50 that is slightly smaller than or equal to the outside diameter 42 of the tube 8. As a result, the retention diaphragm 12 is frictionally secured to the tube 8, but can be adjusted by the user along the outside diameter 42 of the tube 8 by the application of an appropriate force. The adjustability of the retention diaphragm 12 allows the anti-snoring device 10 to conform to the user's particular anatomy.

[0037] The retention diaphragm 12 may have any shape and size, as long as it fits comfortably within the user's mouth between the user's inner lips and/or inner cheek and an outer surface of the user's teeth. For example, the retention diaphragm 12 may be circular, rectangular, square, oval-shaped or any other suitable shape. In the embodiment shown herein, the retention diaphragm 12 has a square outer perimeter or shape, having sides that are approximately {fraction (3/4)} inch to approximately 1½ inch. The square shape helps to prevent rotation of the device 10 when it is in use as described above. In the depicted embodiment, the retention diaphragm 12 has an outer perimeter that is square having 1 inch sides, wherein the opening 50 is circular with a diameter of approximately 28 Fr and the tube 8 has an outside diameter 42 of approximately 28 Fr. In the embodiments depicted, the retention diaphragm 12 has a thickness T of approximately 0.030 inches to approximately 0.060 inches.

[0038] In the embodiment of FIGS. 2A-2C, each of the segments of the tube 8 (the extraoral segment 14, the intermediate segment 16, and the intraoral segment 18) additionally contains side openings or side ventilation openings 24A-24G. The ventilation openings 24A-24G serve to maximize airflow that may be restricted, for example by pillows, bed sheets or other objects obstructing the open end 20 of the extraoral segment 14 and/or soft tissue or other objects obstructing the open end 21 of the intraoral segment 18.

[0039] For added ergonomic effect and comfort, and for proper fitting in the user's mouth, the anti-snoring device 10 depicted in FIG. 1A-2C has a preformed bend such that a convex side 44 of the tube 8 and an opposite concave side 45 of the tube 8 are curved to closely follow the shape of a typical user's dentition. For example, in one embodiment the bend approximates an arc of a circle having a radius in the range of approximately 2.5 inches to approximately 5.0 inches, such as 4.0 inches.

[0040] In the depicted embodiment the ventilation openings 24A-24G are circular in shape with a diameter of approximately 5 mm. In this embodiment, the extraoral segment 14 contains one ventilation opening 24A disposed on the convex side 44 of the tube 8, the intermediate segment 16 contains two ventilation openings 24B and 24C disposed on an upper 46 side, between the convex 44 and concave 45 sides, of the tube 8, and two ventilation openings 24D and 24E disposed on an opposite lower 48 side of the tube 8, and the intraoral segment 18 contains two ventilation openings 24F and 24G disposed on the convex side 44 of the tube 8 and one ventilation opening 24H disposed on the concave side 45 of the tube 8.

[0041] However, the ventilation openings 24A-24G may have any size and shape and each segment 14, 16 and 18 may contain any number of ventilation openings 24A-24G as long as the ventilation openings 24A-24G allow airflow to enter into the tube 8 and allow sufficient airflow through the tube 8 when the openings 20 and 21 at the extraoral 14 and the intraoral 18 segments are obstructed. The ventilation openings 24A-24G may also be disposed on the tube 8 at positions other than that shown in FIGS. 2A-2C. However, the positions shown minimizes the likelihood that the ventilation openings 24A-24G will be obstructed.

[0042] For example, positioning ventilation openings in the convex side 44 of the extraoral segment 14 minimizes the likelihood that the user's outer lips will obstruct the ventilation openings in the extraoral segment 14 since the user's lips are adjacent to the concave side 45 of the tube 8 when the anti-snoring device 10 is in use; positioning ventilation openings between the convex 44 and concave 45 sides in the upper 46 and/or lower 48 sides of the intermediate segment 16 minimizes the likelihood that the inner surface 26 of the user's inner cheek and/or the outer surface 28 of the of the user's dentition will obstruct the ventilation openings in the intermediate segment 16; and positioning ventilation openings in the concave 45 and the convex 44 sides of the intraoral segment 18 minimizes the likelihood that the user's tongue or soft palate will obstruct the ventilation openings in the intraoral segment 18.

[0043] The preformed bend of the anti-snoring device 10, having the convex 44 and the concave 45 sides that are curved to closely follow the shape of a typical user's dentition, facilitates the user in properly inserting the anti-snoring device 10 into the user's mouth and ensures that when the anti-snoring device 10 is inserted properly, the ventilation openings 24A-24G are properly aligned within the user's mouth. However, as shown in FIG. 3, when the user positions the intraoral segment 18 beyond the retromolar space 27 in the user's mouth, into the oropharynx and terminating between the posterior tongue and the soft palate, the intraoral segment 18 may bend inwardly more sharply than the preformed bend for proper placement in the user's mouth. In one embodiment, the above described preformed bend contains an additional inward bend 60 near the junction of the intermediate 16 and intraoral 18 segments as shown in FIG. 3. The inward bend 60 is bent at an angle &agr; in the range of approximately 65 degrees to 135 degrees, such as 100 degrees.

[0044] In the embodiment of FIG. 1A, the open end 21 of the intraoral segment 18 is cut straight across the tube 8, i.e. approximately straight across from the upper side 46 of the tube 8 to a lower side 48 of the tube 8. In the embodiments of FIGS. 1B-2C, the open end 21A of the intraoral segment 18 is angled starting from the upper side 46 of the tube 8 to a lower side 48 of the tube 8 at an angle. In one embodiment, this angle is approximately 45 degrees, however, in other embodiments larger or smaller angles may be used. The angled open end 21A of the intraoral segment 18 facilitates insertion of the intraoral segment 18 into the retromolar space 27. In addition, the angled open end 21A of the intraoral segment 18 makes it less likely that the tongue or soft palate will occlude the open end 21A when the anti-snoring device 10 is in use.

[0045] In one embodiment, the tube 8 has a predetermined length of approximately 9 cm to approximately 13 cm. Although other lengths may be used, when the tube length is longer than 15 cm the extraoral segment 14 extends too far from the typical user's mouth, which may cause the extraoral segment 14 to bind or become obstructed, and when the tube length is shorter than 9 cm the tube 8 is not long enough for both the extraoral segment 14 to extend from the user's mouth and the intraoral segment 18 to extend into the oropharynx 30 of the user's mouth for a typical user. In one embodiment, the tube 8 has a length of 12 cm.

[0046] In one embodiment, the tube 8, the retention diaphragm 12 and the stop 13 are each composed of a flexible, elastic material, such as a non-latex polyvinyl chloride material. When the anti-snoring device 10 is composed of a flexible, elastic material, the anti-snoring device 10 is allowed to negotiate the contours of the user's buccopharyngeal pathway 11 while maintaining user comfort. In addition, the flexibility and elasticity of the anti-snoring device 10 allows for a compression of the anti-snoring device 10 during normal sleeping functions, such as swallowing and teeth clenching, while allowing the anti-snoring device 10 to regain its original dimension when those force are relieved.

[0047] In the depicted embodiments, the outside diameter 42 of the tube 8 is approximately 26 Fr to approximately 36 Fr, the inside diameter 43 of the tube is approximately 24 Fr to approximately 34 Fr, and the thickness 41 of the tube 8 is approximately 0.3 Fr to approximately 2.5 Fr. In one embodiment, the outside diameter 42 of the tube 8 is approximately 28 Fr, the inside diameter 43 of the tube 8 is approximately 26 Fr and the thickness 41 of the tube 8 is approximately 1.0 Fr.

[0048] The outside diameter 42 of the tube 8 may be larger than 36 Fr, but at diameters larger than 36 Fr user comfort begins to decrease. The inside diameter 43 of the tube 8 may be smaller than 26 Fr, but sufficient airflow begins to diminish at 26 Fr. The thickness 41 of the tube 8 may be smaller than 0.3 Fr or larger than 2.5 Fr, but at smaller thicknesses the device 10 becomes too flimsy and a larger thicknesses the device 10 becomes too stiff.

[0049] In one embodiment, all of the outer edges of the tube 8, the retention diaphragm 12 and the stop 13 are rounded to avoid abrasion or irritation of the user's soft tissue when the device is in use, as described above.

[0050] Any of the embodiments described above may include the preformed shape as shown in FIG. 5. In the preformed shape of FIG. 5, the tube 8 includes a first concave surface 54A and an opposite first convex surface 56A that each integrally adjoin, respectively, a second convex surface 54B and an opposite second concave surface 56B, such that the tube 8 is approximately “S-shaped”. In one embodiment, the first concave surface 54A and the first convex surface 56A are disposed on the extraoral 14 and intermediate 16 segments and the second convex surface 54B and the second concave surface 56B are disposed 16 on the intraoral segment 18.

[0051] In any of the embodiments shown in FIGS. 1-3, the stop 13 may be formed as a preformed expansion in the tube 8 (as is shown in FIGS. 4A and 4B), that extends from outside diameter 42 of the tube 8. In one embodiment, the preformed expansion extends annularly about the tube 8. In another embodiment, the preformed expansion extends from the outside diameter of the tube 8, but does not extend annularly about the tube 8.

[0052] In one embodiment shown in FIGS. 4A and 4B, the dimensions of the stop 13 when the stop 13 is formed as a preformed expansion in the tube 8 (the outer diameter d, the inside diameter id, the length l, and the thickness t) are approximately the same as the dimensional ranges given above in the embodiments where the stop 13 is a sleeve.

[0053] The preceding description has been presented with reference to various embodiments of the invention. Persons skilled in the art and technology to which this invention pertains will appreciate that alterations and changes in the described structures and methods of operation can be practiced without meaningfully departing from the principle, spirit and scope of this invention. Accordingly, the foregoing description should not be read as pertaining only to the precise structures described and shown in the accompanying drawings, but rather should be read as consistent with and as support for the following claims, which are to have their fullest and fairest scope.

an extraoral segment, which extends to the proximal end of the tube and has at least one opening, for extending beyond the user's outer lips;
an intraoral segment, which extends to the distal end of the tube and has at least one opening, having a sufficient length for extending beyond a retromolar space in the user's mouth, into the oropharynx and terminating between the posterior tongue and the soft palate; and
an intermediate segment, which extends between the extraoral and intraoral segments, having a sufficient length for extending along the buccopharyngeal pathway of the user's mouth; and
a stop extending from the outer perimeter of the tube on the intraoral segment for securing the intraoral segment within the user's oropharynx, wherein the outer perimeter of the stop is larger than the outer perimeter of the tube, and wherein the tube comprises an outer preformed bend having a convex side and an opposite concave side.

26. The anti-snoring device of claim 25, wherein the stop comprises an outer perimeter that is larger than the retromolar space and the outer perimeter of the tube is smaller than the retromolar space.

27. The anti-snoring device of claim 25, wherein the stop comprises an inner perimeter that is slightly smaller than the outer perimeter of the tube and wherein the stop has a thickness in the range of approximately 0.3 French to approximately 2.5 French.

28. The anti-snoring device of claim 25, wherein the extraoral segment comprises an open end and wherein the intraoral segment comprises an open end.

29. The anti-snoring device of claim 28, wherein the extraoral segment comprises at least one ventilation opening disposed on the convex side of the tube, wherein the intermediate segment contains at least one ventilation opening disposed on at least one of an upper side between the convex and concave sides of the tube and an opposite lower side of the tube, and wherein the intraoral segment comprises at least one ventilation opening disposed on at least one of the convex side and the concave side of the tube.

30. The anti-snoring device of claim 25, further comprising a retention diaphragm on the intermediate segment of the tube for securing the intermediate segment within the user's buccopharyngeal pathway.

31. A method of reducing snoring in a user's mouth comprising:

inserting into the user's mouth a flexible hollow tube having proximal and distal ends;
positioning an extraoral segment of the tube, which extends to the proximal end of the tube and has at least one opening, exterior to the user's lips;
positioning an intraoral segment of the tube, which extends to the distal end of the tube and has at least one opening, beyond a retromolar space in the user's mouth, into the oropharynx and terminating between the posterior tongue and the soft palate; and
positioning an intermediate segment of the tube, which extends between the extraoral and intraoral segments, along the buccopharyngeal pathway of the user's mouth.

32. The method of claim 31, further comprising securing the intermediate segment within the buccopharyngeal pathway.

33. The method of claim 32, wherein securing the intermediate segment within the buccopharyngeal pathway comprises positioning a retention diaphragm between the user's inner lips and an outer surface of the user's teeth.

34. The method of claim 31, further comprising securing the intraoral segment within the oropharynx.

35. The method of claim 34, wherein securing the intraoral segment within the oropharynx comprises positioning a stop adjacent to a last tooth that is adjacent to the user's retromolar space.

36. The method of claim 31, further comprising separating at least a portion of the posterior tongue and the soft palate by positioning at least a portion of the intraoral segment therebetween.
