A device for delivering fluid to a nasal cavity comprises an elongated member comprising a hollow exterior cannula and a hollow interior cannula. The interior cannula is flexible, is at least partially housed within the exterior cannula, and comprises an inlet for intake of the fluid and at least one outlet for ejecting the fluid. The exterior cannula has outlets for ejecting the fluid which are positioned within the nasal cavity by inserting the distal end of the device through a given nostril. A portion of the device has a continuously curving centerline that divides the device into a first and second lateral section. At least one outlet is positioned in each of the first and second lateral sections. Rotation of the distal section of the interior cannula within the exterior cannula permits the ejection of fluid predominantly out of outlets on respective lateral sides of the outer cannula.
