CLAIMS

What is claimed is:

1. A resettable respiratory inhaler training device, comprising;

a device housing comprising an unlocked position and a locked position, the housing comprising a chamber;

a cartridge for placement into the chamber, the cartridge comprising a body and a base, wherein the body is receivable within the chamber, said cartridge comprises a status indicator window to indicate a new or used status of the cartridge, an aperture in the base of the cartridge, and a shutter to selectively open or close the aperture; and

a reset cap comprising a protrusion for interfacing with the aperture during reset of the device;

wherein removal of the cartridge from the device housing changes the status in the indicator window from the used status to the new status and resets the cartridge for a subsequent use.

2. The resettable respiratory inhaler training device of claim 1, wherein the device housing comprises an upper portion and a lower portion, wherein the device housing lower portion is rotatable relative to the upper portion.

3. The resettable respiratory inhaler training device of claim 2, further comprising a biasing member associated with the lower portion of the device housing, for rotating the lower portion in a second direction, unlocking and resetting the device for a subsequent use.

5. The resettable respiratory inhaler training device of claim 2, wherein the upper portion comprises an upper interfacing surface, and the lower portion comprises a lower interfacing surface, wherein the upper and lower interfacing surfaces interface upon rotation of the lower portion relative to the upper portion during removal of the cartridge.

6. The resettable respiratory inhaler training device of claim 5, wherein the interface between the upper and lower interfacing surfaces causes radial movement of the lower portion.

7. The resettable respiratory inhaler training device of claim 1, 4, 5, and 6, wherein rotation of the reset cap in a first direction on the device housing rotates the lower portion in the first direction, extends the cartridge from the chamber and ejects the reset cap from the device housing.

8. The resettable respiratory inhaler training device of claim 7, wherein upon removal of the cartridge from the device housing, the aperture is open.

9. The resettable respiratory inhaler training device of claims 1, 7, or 8, wherein prior to removal of the cartridge from the device housing, the aperture is partially obstructed.

10. The resettable respiratory inhaler training device of claim 8 or 9, wherein rotation of the reset cap on the device in a second direction rotates the second portion, and resets the device to an unlocked position.

11. The resettable respiratory inhaler training device of claim 1, wherein the cartridge comprises a primary lock and a secondary lock.

12. The resettable respiratory inhaler training device of claim 11, wherein when the primary and secondary locks are engaged, the aperture is partially obstructed.

13. The resettable respiratory inhaler training device of claim 11, wherein when the primary lock is released and the secondary lock is engaged, the aperture is partially obstructed.

14. The resettable respiratory inhaler training device of claim 11, wherein when the primary lock is released and the secondary lock is released, the aperture is open.

15. The resettable respiratory inhaler training device of claim 7 wherein rotation of the lower portion in the first direction releases the primary lock.

16. The resettable respiratory inhaler training device of claim 1, wherein removal of the cartridge releases the secondary lock.

17. A method for resetting the respiratory inhaler training device of claim 1, comprising: placing a reset cap on a lower portion of the device housing, comprising an upper portion and lower portion wherein the lower portion is rotatable relative to the upper portion;

rotating the reset cap and lower portion of the housing in a first direction relative to the upper portion of the device housing to release the reset cap, extend the cartridge from the chamber, and lock the device housing;

removing the reset cap from the device;

removing the cartridge from the device, wherein removal of the cartridge causes a change of a status in the status indicator window from used to new, resetting the cartridge;

reinserting the cartridge into the device housing changing the status indicator window to used;

replacing the reset cap onto the cartridge;

rotating the reset cap and lower portion of the device housing in a second direction relative to the upper portion to reset the device to an unlocked position for a subsequent training.

18. The method of claim 17, wherein a biasing member rotates the lower portion relative to the upper portion.

19. A method for training a user to replace a cartridge of a respiratory inhaler device, comprising:

placing a reset cap on a lower portion of the respiratory inhaler training device of claim 1, wherein the housing comprises an upper portion and lower portion wherein the lower portion is rotatable relative to the upper portion;

rotating the reset cap and lower portion of the housing in a first direction relative to the upper portion of the device housing to release the reset cap, extend the cartridge from the chamber, and lock the device housing;

removing the reset cap from the device;

removing the cartridge from the device, wherein removal of the cartridge causes a change of a status in the status indicator window from used to new, resetting the cartridge;

reinserting the cartridge into the device housing changing the status indicator window to used;

replacing the reset cap onto the device;

rotating the reset cap and lower portion of the device housing in a second direction relative to the upper portion to reset the device to an unlocked position for a subsequent training.

20. The method of claim 19, wherein a biasing member rotates the lower portion relative to the upper portion.
