Device for administering a drug

A device for nasally administering a drug to a user, the device comprising:

• a housing;
• a plurality of first chambers located in the housing, each of the first chambers containing a fluid and arranged in a parallel configuration along a width direction of the housing;
• a plurality of plungers, each plunger of the plurality of plungers movable within a respective first chamber of the plurality of first chambers from a first position to a second position to increase a pressure of the fluid contained in the first chamber;
• a second chamber configured to contain the drug and having an inlet and an outlet, wherein at least part of the second chamber is located in a nozzle of the device, the nozzle configured to be received at least partially in the nose of the user;
• at least one releasable seal located at or adjacent the inlet of the second chamber between the plurality of first chambers and the drug contained in the second chamber, the second chamber, including the outlet, being in selective fluid flow communication with the plurality of first chambers via the releasable seal;
• and
• an actuator comprising a projection extending from a distal end of a first plunger of the plurality of plungers and configured to actuate release of the releasable seal, wherein the releasable seal comprises an interference fit ball, the actuator actuating release of the releasable seal by dislodging the ball from the interference fit;
• wherein moving the plurality of plungers from the first position to the second position causes the actuator to actuate release of the releasable seal to release the fluid under pressure from the plurality of first chambers into the second chamber, thereby entraining the drug in the fluid and causing the drug to be discharged from the outlet for administration;
• wherein the device comprises a manifold that fluidly connects the plurality of first chambers to the inlet of the second chamber, wherein the projection extending from the distal end of the first plunger is configured to extend through the manifold to actuate release of the releasable seal.

• an actuator comprising a projection extending from a distal end of a first plunger of the plurality of plungers and configured to actuate release of the releasable seal;
• and
• a common handle connected to each of the plurality of plungers, wherein the plurality of plungers are movable by the common handle from the first position to the second position;
• wherein moving the plurality of plungers from the first position to the second position causes the actuator to actuate release of the releasable seal to release the fluid under pressure from the plurality of first chambers into the second chamber, thereby entraining the drug in the fluid and causing the drug to be discharged from the outlet for administration;
• and
• wherein the device has a length dimension of less than 86mm and a width dimension of less than 55mm when the plurality of plungers are in the first position.
