Adjustable nasal dilator

1. A nasal dilator comprising:

a first leg and a second leg insertable into a pair of respective nasal openings, the first leg and the second leg being separated by a clearance and each of the first and second legs having a first end and a second end, an outwardly facing surface of each of the first end of the first and second legs including a contact region configured to contact an interior surface of a nostril, wherein the first leg and the second leg are movable between an extended position and a retracted position, wherein the first leg and the second leg are integrally formed from a resilient material having a bias toward the extended position and a thickness of at least one of the first leg and the second leg tapers from the second end towards the first end;

a connecting member extending between the first leg and the second leg; and

an adjustment mechanism operably coupled to both the first leg and the second leg, wherein the adjustment mechanism includes a tension shaft that is rotatable about an axis to oppose the bias of the first and second legs towards the extended position and control an outward pressure configured to be applied to each nostril.

2. The nasal dilator of claim 1 , wherein the tension shaft is threadably coupled to at least one of the first leg and the second leg.

3. The nasal dilator of claim 2 , wherein the first and second legs in combination with the connecting member form a body, wherein lateral movement of the tension shaft is restricted relative to the body.

4. The nasal dilator of claim 3 , wherein the tension shaft includes a head arranged at a first end of the tension shaft and a nut arranged at a second end of the tension shaft, the head being located adjacent a first surface of the body and the nut being arranged adjacent a second, opposite side of the body.

5. The nasal dilator of claim 4 , wherein a first through opening is formed in the first leg and a second through opening is formed in the second leg and the tension shaft extends through both the first through opening and the second opening.

6. The nasal dilator of claim 5 , wherein the second through opening is threaded.

7. The nasal dilator of claim 1 , wherein at least one of the first leg and the second leg is formed from a high flexure material.

8. The nasal dilator of claim 1 , wherein the connecting member is formed from a medium flexure material.

9. The nasal dilator of claim 1 , wherein the first leg, the second leg, and the connecting member are integrally formed.

10. The nasal dilator of claim 1 , wherein at least one of the contact region of the first and second legs includes a contoured surface for gripping a nasal surface.

11. The nasal dilator of claim 10 , wherein each of the contact region of the first and second legs is formed by a pad mounted to a distal end of the first leg and the second leg, respectively.

12. The nasal dilator of claim 1 , wherein the first and second legs in combination with the connecting member form a body, wherein at least a portion of the body is coated with a layer of soft material.

13. The nasal dilator of claim 1 , wherein the contact region of the first and second legs each includes at least one gripping feature configured to contact the interior surface of the nostril.

14. A nasal dilator comprising:

a first leg and a second leg insertable into a pair of respective nasal openings, the first leg and the second leg each having a first end and a second end an outwardly facing surface of each of the first end of the first and second legs including a contact region configured to contact an interior surface of a nostril, wherein the first leg and the second leg are movable between an extended position and a retracted position, the first leg being arranged at an angle relative to the second leg in the extended position, wherein the first leg and the second leg are integrally formed from a resilient material having a bias toward the extended position;

a connecting member connected to and extending between the second ends of the first leg and the second leg such that a clearance is defined between the connecting member, the first leg, and the second leg; and

an adjustment mechanism receivable within an opening formed adjacent to the second end of both the first leg and the second leg, wherein the adjustment mechanism includes a tension shaft that extends through the clearance and is rotatable about an axis to oppose the bias of the first and second legs towards the extended position and control an outward pressure configured to be applied to each nostril.
