Intranasal pressure drug delivery device

1. A beneficial agent dispensing device, comprising:

a primary container storing a beneficial agent; and

a dispenser body associated with the primary container and comprising a pressure chamber and a dispensing port, wherein applying a pressurized fluid in the pressure chamber causes penetration of the primary container and wherein the applied pressurized fluid is applied to the primary container to flex the primary container and expel the beneficial agent through the dispensing port,

wherein the dispensing port is fixedly attached to the dispenser body to prevent motion of the dispensing port relative to the dispenser body, and

wherein the dispensing port comprises a fluid pathway providing fluid communication between an interior of the dispenser body and an external environment prior to pressurization.

2. The beneficial agent dispensing device of claim 1 wherein said primary container comprises a blister pack.

3. The beneficial agent dispensing device of claim 2 wherein said blister pack is formed from at least one of a film and a foil.

4. The beneficial agent dispensing device of claim 1 further comprising a pressurized fluid source adapted to provide the applied pressurized fluid.

5. The beneficial agent dispensing device of claim 4 wherein the pressurized fluid source includes a compressed gas cartridge comprising a rupturable membrane and a rupturing pin.

6. The beneficial agent dispensing device of claim 5 further comprising:

an activation mechanism comprising a horizontal plate and a handle disposed to actuate said activation mechanism and to actuate the compressed gas cartridge into the rupturing pin.

7. The beneficial agent dispensing device of claim 1 wherein said primary container comprises a flexible or semi-flexible package.

8. The beneficial agent dispensing device of claim 7 wherein said primary container comprises at least one or more of a blister pack, a molded container, a blow molded container, a sachet, a pouch, a tube, or any combination thereof.

9. The beneficial agent dispensing device of claim 1 wherein said dispensing port comprises at least one of a jet nozzle, a spray nozzle, or a topical applicator.

10. The beneficial agent dispensing device of claim 1 , further comprising another primary container storing a common beneficial agent to the primary container or a different beneficial agent.

11. The beneficial agent dispensing device of claim 1 wherein said primary container comprises a plurality of compartments whose contents are merged upon activation of the dispensing device to reconstitute and form the beneficial agent.

12. The beneficial agent dispensing device of claim 1 further comprising:

a plurality of primary containers including the primary container, wherein contents of the plurality of primary containers are dispensed through said dispensing port.

13. The beneficial agent dispensing device of claim 1 further comprising a cap removably attached to said dispenser body.

14. The beneficial agent dispensing device of claim 1 further comprising a movable activation handle associated with said pressure chamber.

15. The beneficial agent dispensing device of claim 14 further comprising a piston associated with said pressure chamber and movable upon actuation of said handle from a pre-activation position to an activation position.

16. The beneficial agent dispensing device of claim 15 further comprising a piston return spring that is biased to retract the piston and urge the piston into the pre-activation position.

17. The beneficial agent dispensing device of claim 1 further comprising a bleed hole to assist in regulating pressure within said pressure chamber.

18. The beneficial agent dispensing device of claim 1 further comprising:

a tether comprising a connection between a removable cap and a connector, wherein said connector is configured to attach to a firm object.

19. The beneficial agent dispensing device of claim 18 , further comprising:

a second body, wherein the dispenser body is able to retract into or extend from the second body, wherein a retracted configuration of the second body covers said cap so as to prevent said cap from being removed in the retracted configuration; and

wherein an extended configuration permits removal of said cap.

20. The beneficial agent dispensing device of claim 18 , wherein said connector is a carabiner.
