Claim:
A nasal lavage device comprising: a hand-held controller; a gravity-fed source of saline solution received on the controller; an effluent receptacle received on the controller; a nasal interface configured for engaging nostrils of an associated user of the device wherein the source is above the nasal interface and provides gravity-fed flow of the saline solution through the nasal interface, and the receptacle is positioned below the interface; a fluid passageway disposed to communicate the source of saline solution with the effluent receptacle from the nasal interface through a nasal cavity of the associated user; and a cartridge selectively separable from the controller, wherein the cartridge comprises the nasal interface and at least a portion of the fluid passageway, wherein the nasal interface, the fluid passageway and the cartridge are all included in the controller and wherein removal of the cartridge from the controller disconnects the nasal interface from the source.
