Abstract
A delivery tube and cap are configured to be connected to a container that houses fluid to be delivered to a nasal cavity. The delivery tube includes an inner cannula that is positioned within an outer cannula. Each of the cannulas includes a first outlet with one or more openings aligned along a first lateral section and a second outlet with one or more openings aligned along a second lateral section. The delivery tube and cap are configured to provide relative axial movement between the cannulas. The cannulas are positionable between a first axial position that aligns the first outlets along the first lateral section of the delivery tube to deliver the fluid out of the device in a first lateral direction, and a second axial position that aligns the second outlets along the second lateral section to deliver fluid out of the device in a second lateral direction.
