Nasal drug delivery device

A device for delivering a compound to an upper nasal cavity comprising:

• a housing body comprising:
• an actuator configured to move relative to the housing body, wherein actuation of the actuator is configured to actuate a canister thereby releasing a contained propellant;
• a stem protruding from the housing body, the stem comprising a delivery opening at a distal end of the stem and a mating interface positioned about the delivery opening, the mating interface comprising an opening, wherein the mating interface is configured to mate with a nozzle containing the compound;
• and
• a release button positioned within the housing body and configured to move relative to the housing body, the release button directly connected to a securing latch that is configured to protrude through the opening of the mating interface, wherein the securing latch is configured to mate with a reciprocal securing interface on the nozzle, thereby coupling the nozzle to the mating interface, and wherein actuation of the release button is configured to displace the securing latch from the reciprocal securing interface, thereby decoupling the nozzle from the mating interface;
• a junction positioned within the housing body, the junction comprising:
• a base;
• a first branch of the junction extending from the base, the first branch comprising a propellant channel configured to be in fluid communication with the canister;
• and
• a second branch of the junction extending from the base, the second branch in fluid communication with the first branch;
• and
• a coupling mechanism configured to removably couple and decouple the nozzle coupled to the stem, the coupling mechanism comprising:
• a compression spring positioned about a distal end of the second branch;
• an ejector sleeve coupled to a distal end of the compression spring, the ejector sleeve configured to couple to a portion of the nozzle, wherein the ejector sleeve is configured to translate between a first position, in which the compression spring is at rest, and a second position, in which the compression spring is compressed;
• and
• wherein when the nozzle is coupled to the stem, the ejector sleeve is configured to be in the second position, and wherein when the release button is depressed, the securing latch is configured to release the nozzle, thereby enabling the ejector sleeve to return to the first position and decoupling the nozzle from the stem.
