Devices and Methods for Delivering Fluid to a Nasal Cavity

A device to deliver fluid from a container to a nasal cavity, the device comprising:

• a selector and a nozzle that are connected together and configured to connect to the container;
• the selector comprising an opening configured to align with an outlet in the container;
• the nozzle comprising:
• a base and an outwardly-extending extension, the extension comprising a length measured between a proximal end at the base and an opposing distal end;
• a first passage that extends along the extension and comprises a first inlet at the base and first openings that face just towards the distal end and a first lateral side of the extension to expel the fluid from the first openings and to prevent the fluid from being expelled from a second lateral side of the extension;
• a second passage spaced away from the first passage, the second passage extends along the extension and comprises a second inlet at the base and second openings that face just towards the distal end and the second lateral side of the extension to expel the fluid from the second openings and to prevent the fluid from being expelled from the first lateral side of the extension;
• the nozzle being rotatable relative to the selector between a first position to align the first passage with the outlet in the container and the second passage being misaligned with the outlet, and a second position to align the second passage with the outlet in the container and the first passage being misaligned with the outlet.

A method of delivering fluid from a container to a nasal cavity, the method comprising:

• rotating a nozzle relative to a selector to a first position and aligning a first passage of the nozzle with an outlet of the container while the nozzle is connected to the selector and both the nozzle and the selector are connected to the container;
• directing the fluid that is expelled from the container through the first passage that extends along the length of the nozzle and out through first openings that face outward towards a distal end and a first lateral side of the nozzle;
• while in the first position, positioning a second passage of the nozzle away from the outlet and preventing the fluid from being moved into the second passage and preventing the fluid from being expelled outward from a second lateral side of the nozzle;
• rotating the nozzle relative to the selector to a second position and aligning the second passage of the nozzle with the outlet of the container while the nozzle is connected to the selector and both the nozzle and the selector are connected to the container;
• directing the fluid that is expelled from the container through the second passage that extends along the length of the nozzle and out through second openings that face outward towards the distal end and the second lateral side of the nozzle;
• and
• while in the second position, positioning the first passage of the nozzle away from the outlet and preventing the fluid from being moved into the second passage and preventing the fluid from being expelled outward from the first lateral side of the nozzle.
