First Claim
Patent Images
1. A dose setting mechanism for use with a drug delivery device, the dose setting mechanism comprising:
- a dose setter for selecting a dose; and
a locking mechanism configured to prevent movement of the dose setter and selection of the dose,wherein the locking mechanism is configured such that inserting a correct cartridge into the drug delivery device unlocks the locking mechanism so as to allow movement of the dose setter and selection of the dose, andwherein the locking mechanism is configured such that inserting an incorrect cartridge into the drug delivery device locks the locking mechanism so as to prevent the dose setter from setting a dose, wherein the locking mechanism prevents the dose setter from rotating, and wherein, when the correct cartridge is inserted into the drug delivery device, the locking mechanism unlocks so as to allow the dose setter to rotate.

Abstract
A dose setting mechanism having a locking mechanism for preventing selection of a dose in a drug delivery device is disclosed. The dose setting mechanism includes a locking mechanism that prevents movement of the dose setting mechanism. When a correct cartridge is inserted into the drug delivery device, the locking mechanism unlocks so as to allow movement of the dose setting mechanism. In one arrangement, the locking mechanism prevents rotation of the dose setting mechanism.

15. A dose setting mechanism for use with a drug delivery device, the dose setting mechanism comprising:
-
a body a dose setter for selecting a dose; and a locking mechanism configured to prevent movement of the dose setter and selection of the dose, wherein the locking mechanism comprises a movable locking element supported by the body, mechanically engageable with the dose setter, and movable between a first position and a second position, wherein, when in the first position, the movable locking element prevents the dose setter from rotating relative to the body, and wherein when the movable locking element is in the second position the dose setter is free to rotate relative to the body, and wherein the locking mechanism is configured such that inserting a correct cartridge into the drug delivery device moves the movable locking element from the first position into the second position to unlock the locking mechanism and to allow movement of the dose setter and selection of the dose. - View Dependent Claims (16, 17, 18, 19, 20)
