DRUG DELIVERY DEVICE

摘要

A drug delivery device having a fixed dose setting mechanism with a biasing element (114, 214, 314). The drug delivery device includes a first dose setting mechanism (102, 202, 203), where the first dose setting mechanism is operably coupled to a primary reservoir holding a first medicament (1). The device also includes a dose setter (112, 212, 312) operably coupled to the first dose setting mechanism. The device further includes second dose setting mechanism (104, 204, 304), where the second dose setting mechanism is operably coupled to a secondary reservoir (5) 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.
