Drug Delivery Device and Method for Sequentially Delivering at Least Two Medicaments

Abstract

Various examples of a drug delivery device and corresponding method for sequentially delivering at least two medicaments via a single dispense interface are provided. In one example, the device includes a variable dose setting mechanism operably connected to a first cartridge containing a first medicament, a fixed dose setting mechanism operably connected to a second cartridge containing a second medicament, a dose setter for setting a user settable dose of the first medicament and a fixed dose of the second medicament, and a connecting feature for detachably connecting the variable dose setting mechanism to the fixed dose setting mechanism. During setting of the fixed dose of the second medicament, the rotationally driven variable dose setting mechanism and the fixed dose setting mechanism are connected via the connecting feature, however, during setting of the user settable dose of the first medicament, the rotationally driven variable dose setting mechanism and the fixed dose setting mechanism are not connected.

Dependencies are inferred from the claim text.
