1. A medicament delivery device comprising:
a chamber housing defining an interior volume, wherein the interior volume defines a medicament delivery flow path; and
a vibration inducing device disposed in and communicating with the interior volume, wherein the vibration inducing device is operable to introduce vibrations into the medicament delivery flow path, wherein the vibration inducing device is configured to induce vibrations in the medicament delivery flow path in response to an inhalation flow along the medicament delivery flow path actuating the vibration inducting device.
2. The medicament delivery device of claim 1 wherein the chamber housing comprises a holding chamber having an input end, an output end, and a one-way inhalation valve positioned at the output end, wherein the medicament delivery flow path is defined between the input and output ends.
3. The medicament delivery device of claim 2 wherein the vibration inducing device comprises a rotating turbine communicating with the interior volume.
4. The medicament delivery device of claim 3 wherein the rotating turbine is rotatable in response to a gas flow in the flow channel.
5. The medicament delivery device of claim 2 wherein the vibration inducing device comprises a vibratory device communicating with the interior volume.
6. The medicament delivery device of claim 5 wherein the vibratory device comprises a tuning fork.
7. The medicament delivery device of claim 6 further comprising an actuator engagable with the tuning fork.
8. The medicament delivery device of claim 7 wherein the actuator comprises a moveable pin.
9. The medicament delivery device of claim 7 further comprising a sensor operably connected to a controller, wherein the controller provides an input to the actuator.
10. The medicament delivery device of claim 9 wherein the sensor comprises at least one of a flow pressure sensor and/or a microphone.
11. The medicament delivery device of claim 1 wherein the vibration inducing device is wirelessly connected to a user interface.
12. The medicament delivery device of claim 11 wherein the user interface is operable to provide audio, visual and/or haptic feedback to user.
13. The medicament delivery device of claim 2 wherein the vibration inducing device comprises a resonating chamber having an inlet and an outlet communicating with the interior volume of the chamber housing, and a pea disposed in the resonating chamber, wherein the pea is moveable within the resonating chamber in response to a flow between the input and output.
14. The medicament delivery device of claim 13 further comprising an edge spaced apart from the inlet adjacent the outlet.
15. The medicament delivery device of claim 13 wherein the outlet comprises a sound reflector and/or airflow converter directed to the output end.
16. The medicament delivery device of claim 13 wherein the inlet faces the input end of the first chamber.
17. The medicament delivery device of claim 1 wherein the vibration inducing device comprises a cantilever spring and a mass coupled to the spring.
18. A medicament delivery device comprising:
a chamber housing defining an interior volume, wherein the interior volume defines a medicament delivery flow path, and wherein the chamber housing comprises a passage opening defining in part the medicament delivery flow path; and
a vibration inducing device communicating with the interior volume, wherein the vibration inducing device is operable to introduce vibrations into the flow path, wherein the vibration inducing device comprises a cantilever spring and a mass coupled to the spring, and wherein the vibration inducing device further comprises a valve connected to the cantilever spring, wherein the valve is disposed adjacent the passage opening and is moveable relative to the passage opening.
19. A medicament delivery assembly comprising the medicament delivery device of claim 2 and a drug delivery device coupled to the input end.
20. A method of delivering a medicament comprising:
providing a medicament delivery device of claim 2 ;
introducing a medicament into the interior volume of the chamber housing;
creating a flow through the interior volume of the chamber housing;
inducing vibrations in the interior volume of the chamber housing with the vibration inducing device; and
inhaling the medicament.
21. The method of claim 20 wherein the inducing vibrations is initiated prior to the introducing the medicament into the interior volume.
22. The method of claim 20 wherein inducing the vibrations in the interior volume comprises inducing the vibrations with the vibration inducing device in response to the flow through the interior volume.
23. The medicament delivery device of claim 1 , wherein the vibration inducing device is configured to induce vibrations in the medicament delivery flow path in response to shaking the chamber housing.
