摘要：
Devices and methods for delivering fluid to the nasal cavity that include a delivery tube (20) and cap (40) configured to be connected to a container (100) that houses the fluid. The delivery tube (20) includes an inner cannula (31) that is positioned within an outer cannula (21). Each of the cannulas (31, 21) includes a first outlet with one or more openings (25) aligned along a first lateral section and a second outlet with one or more openings (25) aligned along a second lateral section. The cap (40) is configured to secure the delivery tube (20) to the container (100). The delivery tube (20) and cap (40) are configured to provide relative axial movement between the cannulas (31, 21). The cannulas (31, 21) are positionable between a first axial position that aligns the first outlets along the first lateral section of the delivery tube (20) to deliver the fluid to a first portion of the nasal cavity, and a second axial position that aligns the second outlets along the second lateral section to deliver fluid to a second portion of the nasal cavity.
