Claims15
A medication delivery pen comprising:
- a pen-needle assembly;
- a vial retainer including a vial containing a medication to be delivered and having said pen-needle removably attached to a distal end;
- a housing having said vial retainer mounted to a distal end and including;
- a dose control mechanism for setting a desired dose to be delivered from the vial;
- a drive mechanism for dispensing the desired dose from the vial when in an armed condition;
- means for arming said drive mechanism into the armed condition;
- and
- means for indicating whether said drive mechanism is in the armed position;
- wherein said dose control mechanism includes a dose knob and a dose barrel, and
- wherein said means for arming said drive mechanism arms said drive mechanism when said dose knob is pulled a predetermined distance out of said housing, said arming means including:
- a sliding sleeve slidably mounted on said dose knob having a distal edge and a detent on an outer surface;
- and
- a shoulder on a proximal side of said dose barrel that contacts said distal edge of said sliding sleeve to push said sliding sleeve out of the proximal end of a pawl assembly on said housing and into the armed position.
