DRUG DELIVERY DEVICE HAVING A TRIGGER |
摘要 |
<p>A drug delivery device having a trigger biasing member (260) that provides dispense assistance. The drug delivery device includes a variable dose setting mechanism (202) that is operably coupled to a primary reservoir (214) holding a first medicament. The drug delivery device also includes a fixed dose setting mechanism (204) that is operably coupled to a secondary reservoir (218) holding a second medicament. The fixed dose setting mechanism comprises a trigger biasing member or spring. In addition, the drug delivery device includes a mechanical coupling (206) that operably couples the variable dose setting mechanism and the fixed dose setting mechanism. During dose setting, activation of a single dose setter sets a variable dose of the first medicament. Setting of a minimum dose of the first medicament causes a fixed dose of the second medicament to be automatically set, and, during dispense, the trigger spring at least assists with the dispense of the fixed dose of the second medicament.</p> |
