1. A nasal drug delivery device comprising:

  • a housing including a spray port;

    a reservoir housing a liquidous medicament;

    a selectively actuable pump supported by said housing and operatively connecting said reservoir to said spray port;

    said pump having a plunger controlling operation thereof;

    a deformable drive element operatively connected to said plunger and elastically deformable between a higher potential energy state and lower potential energy state;

    a breath actuated triggering mechanism associated with said housing and including a mouthpiece and a diaphragm, said triggering mechanism controlling release of said drive element from said higher potential energy state to said lower potential energy state wherein a pressure differential across said diaphragm, higher towards said mouthpiece, causes said drive element to change from said higher state to said lower state, said plunger moving in response thereto to thereby cause said pump to supply said medicament to said spray port.
