摘要：
A drug delivery device having a fixed dose setting mechanism with a biasing element. The drug delivery device includes a first dose setting mechanism, where the first dose setting mechanism is operably coupled to a primary reservoir holding a first medicament. The device also includes a dose setter operably coupled to the first dose setting mechanism. The device further includes second dose setting mechanism, where the second dose setting mechanism is operably coupled to a secondary reservoir holding a second medicament. The second dose setting mechanism is mechanically linked to the first dose setting mechanism, and the second dose setting mechanism includes a biasing element. The dose setter is configured to set a variable dose of the first medicament and automatically set a fixed dose of the second medicament upon activation. In addition, the biasing element is configured to assist with dispense of the second medicament.
