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 an outlet. 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 outlets to deliver the fluid out of the device in a lateral direction and a second axial position that misaligns the outlets to impede the fluid from being delivered out of the device in the lateral direction.
