Systems and methods for nasal irrigation
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.
1. A nasal irrigation device, comprising:
a source of irrigant;
an effluent receptacle; and
a housing located between the source of irrigant and the effluent receptacle, the housing comprising:
a vacuum source for applying a relative vacuum to the effluent receptacle;
a nasal interface comprising first and second nozzles configured to simultaneously contact first and second nostrils, respectively, of a device user's nose; and
a fluid passageway for communicating the irrigant from the source of irrigant to the effluent receptacle via a nasal cavity of the device user, wherein the fluid passageway comprises a supply conduit from the source of irrigant 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.
2. The nasal irrigation device of claim 1 , wherein the effluent receptacle is located below the source of irrigant.
3. The nasal irrigation device of claim 1 further comprising a trigger for stopping flow of the irrigant through the fluid passageway.
4. The nasal irrigation device of claim 1 , wherein the nasal interface is part of the fluid passageway.
5. The nasal irrigation device of claim 1 , wherein the nasal interface is selectively removable from the housing.
6. The nasal irrigation device of claim 1 , wherein the nasal interface is located above the effluent receptacle.
7. The nasal irrigation device of claim 1 , wherein the housing comprises a top cover with an opening for the source of irrigant and a lower housing wall with a mount for the effluent receptacle.
8. The nasal irrigation device of claim 1 , wherein the vacuum source comprises a pump assembly.
9. The nasal irrigation device of claim 8 , wherein the pump assembly is battery powered.
10. The nasal irrigation device of claim 8 further comprising a vacuum conduit for directing the relative vacuum to the effluent receptacle from the pump assembly.
11. The nasal irrigation device of claim 1 , wherein the housing further comprises a battery source for powering the vacuum source.
12. The nasal irrigation device of claim 1 , wherein the housing further comprises a switch for selectively controlling the vacuum source.
13. The nasal irrigation device of claim 1 , wherein the source of irrigant and the effluent receptacle are selectively separable from the housing.
14. The nasal irrigation device of claim 1 , further comprising a pressure relief valve associated with the effluent receptacle.
15. The nasal irrigation device of claim 1 , further comprising a pressure relief conduit and a pressure relief valve in communication with the source of irrigant, which permits air to replace the irrigant.
