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 (26)

1. A nasal irrigation device comprising:

a source of saline solution;

an effluent receptacle, wherein the source of saline solution is positioned above the effluent receptacle;

a nasal interface for engaging a device user's first and second nostrils with first and second nozzles, wherein the nasal interface is disposed above the effluent receptacle;

a powered pressure source for forming a negative relative pressure in the effluent receptacle; and

a fluid passageway to communicate the source of saline solution with the effluent receptacle through first and second fluid conduits and a nasal cavity of the user wherein the first and second nozzles are respectively mounted to the first and second fluid conduits and wherein a flow of the saline solution into the fluid passageway and the nasal cavity is effected by the negative relative pressure.

2. The device of claim 1 wherein the powered pressure source comprises a pump assembly.

3. The device of claim 2 wherein the pump assembly is battery powered.

4. The device of claim 3 including a rechargeable battery for powering the pump assembly.

5. The device of claim 2 wherein a vacuum conduit directs the negative relative pressure to the effluent receptacle from the pump assembly.

6. The device of claim 1 wherein the source of saline solution and the effluent receptacle are selectively separable from the device.

7. The device of claim 6 wherein the source of saline solution and the effluent receptacle comprise an interchangeable cartridge.

8. The device of claim 1 wherein the nasal interface is selectively removable.

9. The device of claim 8 wherein the nasal interface is adjustable to the device user's anatomy.

10. The device of claim 1 including a pressure relief valve associated with the effluent receptacle.

11. The device of claim 1 , further comprising a pressure relief conduit and a pressure relief valve in communication with the source of saline solution, which permit air to replace the saline solution.

12. The device of claim 11 , further comprising a housing that includes a top cover and a lower housing wall, the top cover including a source bottle opening for the source of saline solution; and

wherein the powered pressure source, the fluid passageway, the pressure relief conduit, and the pressure relief valve are located within the housing.

13. A nasal irrigation device comprising:

a source of saline solution;

an effluent receptacle, a powered pressure source for forming a negative relative pressure in the effluent receptacle;

a nasal interface for engaging a device user's first and second nostrils with first and second nozzles, wherein the nasal interface is disposed above the effluent receptacle;

a fluid passageway to communicate the source of saline solution with the effluent receptacle through first and second fluid conduits and a nasal cavity of the user wherein the first and second nozzles are respectively mounted to the first and second fluid conduits and wherein a liquid flow of the saline solution into the fluid passageway and the nasal cavity is effected by the negative relative pressure; and

a housing located between the source of saline solution and the effluent receptacle, wherein the housing includes a top cover and a lower housing wall;

wherein the top cover includes an opening for the source of saline solution, and the lower housing wall includes a mount for the effluent receptacle;

wherein the powered pressure source is located within the housing.
