Abstract

Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline solution with the effluent receptacle through the nasal interface and a nasal cavity of a user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The source of saline solution is disposed relative to the device to provide gravitational inducement of the saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and a relative vacuum from the effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of the user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.

Claims (32)

1. A nasal irrigation device, comprising:

a source receptacle;

an effluent receptacle; and

a housing comprising:

a nasal interface comprising first and second nozzles configured to simultaneously contact first and second nostrils, respectively, of a device user's nose, wherein both the nasal interface and the source receptacle are located above the effluent receptacle;

a fluid passageway for communicating irrigant from the source receptacle to the effluent receptacle via a nasal cavity of the device user, wherein the fluid passageway comprises a supply conduit from the source receptacle to the first nozzle and an effluent conduit from the second nozzle to the effluent receptacle, and wherein the supply conduit is separate and distinct from the effluent conduit; and

a vacuum source for applying a relative vacuum to at least a portion of the fluid passageway.

2. The nasal irrigation device of claim 1 , wherein the housing is located at least partially between the source receptacle and the effluent receptacle.

3. The nasal irrigation device of claim 1 , wherein the source receptacle and the effluent receptacle are selectively separable from the housing.

4. The nasal irrigation device of claim 1 , wherein the nasal interface is selectively removable from the housing.

5. The nasal irrigation device of claim 1 , wherein the vacuum source comprises a pump assembly.

6. The nasal irrigation device of claim 5 , wherein the pump assembly is battery powered.

7. The nasal irrigation device of claim 1 , wherein the portion of the fluid passageway to which the relative vacuum is applied comprises at least a portion of the effluent conduit.

8. The nasal irrigation device of claim 1 , wherein the housing further comprises a battery source for powering the vacuum source.

9. The nasal irrigation device of claim 8 , wherein the battery source is rechargeable.

10. The nasal irrigation device of claim 1 , wherein the housing further comprises a switch for selectively controlling the vacuum source.

11. The nasal irrigation device of claim 10 , further comprising a trigger for engaging the switch to selectively control the vacuum source.

12. The nasal irrigation device of claim 1 , further comprising a trigger for controlling a flow of the irrigant through the fluid passageway.

13. The nasal irrigation device of claim 1 , further comprising a pressure relief valve associated with the effluent receptacle.

14. The nasal irrigation device of claim 1 , further comprising a pressure relief conduit and a pressure relief valve in communication with the source receptacle, which permits air to replace the irrigant.

15. The nasal irrigation device of claim 1 , wherein the nasal irrigation device is a hand-held assembly.

16. The nasal irrigation device of claim 1 , wherein the source receptacle is coupled to the housing by at least one of a threaded neck, a pinch fit, or a bayonet mount.

17. The nasal irrigation device of claim 1 , wherein the effluent receptacle is coupled to the housing by at least one of a threaded neck, a pinch fit, or a bayonet mount.

18. The nasal irrigation device of claim 1 , wherein the housing further comprises a base configured to cause the nasal irrigation device to stand upright on a surface.

19. The nasal irrigation device of claim 18 , wherein the base is shaped to match a contour of the effluent receptacle to facilitate support and positioning of the effluent receptacle relative to the housing.

20. The nasal irrigation device of claim 1 , wherein the first and second nozzles are further configured to simultaneously form a fluid-tight seal against the first and second nostrils, respectively, of the device user's nose.

21. The nasal irrigation device of claim 1 , wherein the source receptacle is mounted to the housing.

22. The nasal irrigation device of claim 1 , wherein the effluent receptacle is mounted to the housing.

23. The nasal irrigation device of claim 1 , further comprising a thumb switch for controlling a flow of the irrigant through the fluid passageway and selectively controlling the vacuum source.

24. The nasal irrigation device of claim 1 , wherein the source receptacle is disposed adjacent to the effluent receptacle.

25. The nasal irrigation device of claim 1 , further comprising a trigger for varying a speed of flow of the irrigant.

26. The nasal irrigation device of claim 1 , wherein the relative vacuum is configured to induce a flow of the irrigant.
