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 the user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The saline solution source is disposed relative to the device to provide gravitational inducement of saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and the relative vacuum from the effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of a 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 hand-held controller;
a source of irrigant;
an effluent receptacle;
a nasal interface comprising first and second nozzles respectively mounted to first and second fluid conduits substantially within and extending from the controller, and spaced to simultaneously engage a first and a second nostril of an associated user, wherein the nasal interface is disposed below the source of irrigant and above the effluent receptacle for gravitational inducement of the irrigant from the source of irrigant, into the first nostril, around a posterior margin of the nasal septum, out of the second nostril, and into the effluent receptacle;
a vacuum source for forming a relative vacuum in the effluent receptacle;
a fluid passageway disposed to communicate a stream of the irrigant from the source to the effluent receptacle through the nasal interface upon sealing engagement of the nasal interface to the nostrils for forming a closed system, and upon urging of the irrigant from the source to the effluent receptacle by a combination of gravitational inducement and the relative vacuum; and
a switch and valve assembly for selectively controlling the vacuum source and the stream of the irrigant through the fluid passageway, and wherein the vacuum source, the fluid passageway, the nasal interface and the switch and valve assembly are self-contained within the controller.
2. The device of claim 1 wherein the vacuum source is an electric motor and pump assembly.
3. The device of claim 2 wherein the electric motor and pump assembly is battery powered.
4. The device of claim 3 including a rechargeable battery for powering the electric motor and pump assembly.
5. The device of claim 1 wherein the source of irrigant and the effluent receptacle are selectively separable from the device.
6. The device of claim 5 wherein the source of irrigant and the effluent receptacle comprise an interchangeable cartridge.
7. The device of claim 1 wherein the first and second nozzles comprise communal nozzles disposed for sealing engagement against the nostrils.
8. The device of claim 1 wherein the nasal interface is selectively removable.
9. The device of claim 1 wherein the nasal interface is adjustable to a user's anatomy.
10. The device of claim 1 further including a handle configured for holding the nasal interface against the nostrils.
11. The device of claim 10 wherein the handle includes control elements that are disposed in the handle to facilitate finger control of the switch and valve assembly upon sealing engagement between the nasal interface and the nostrils.
12. The device of claim 11 wherein the control elements are cooperatively associated for sequentially initiating the relative vacuum before releasing irrigant into the nasal cavity.
13. The device of claim 1 including pressure relief valves associated with the source of irrigant and the effluent receptacle.
14. The device of claim 1 wherein the irrigant comprises a saline solution or a mix thereof including eucalyptus, chamomile, mint, or medicines including antibiotics, steroids or analgesics.
