1. A wearable drug delivery device comprising:
- a handheld portion, including a proximal end, a distal end, and a longitudinal axis extending between the proximal and distal ends;
a trigger portion in slidable engagement with the distal end of the handheld portion;
a needle assembly disposed within the handheld portion and aligned with the longitudinal axis, the needle assembly being movable towards the distal end of the handheld portion to an extended position by a penetration spring when the penetration spring is activated by the trigger portion sliding towards the proximal end of the handheld portion;
a drug vial disposed within the handheld portion alongside the needle assembly, the drug vial being moveable towards the distal end of the handheld portion to a seated position by a vial spring when the vial spring is activated by the trigger portion sliding towards the proximal end of the handheld portion;
an integral drug delivery port formed at the distal end of the handheld portion and transverse to the longitudinal axis of the handheld portion, wherein the needle assembly in the extended position and the drug vial in the seated position are in fluid communication with each other by way of the integral drug delivery port;
a rotator coupled to the drug vial, the rotator and the drug vial being urged towards the distal end of the handheld portion by the vial spring;
a yoke extending from the distal end of the handheld portion towards the proximal end, the rotator rests on the yoke thereby resisting movement toward the distal end of the handheld portion and moving the drug vial to the seated position; and
wherein the trigger portion includes a trigger blade extending from the trigger portion and through the distal end of the handheld portion, the trigger blade in slidable engagement with the rotator and configured to lift the rotator off the yolk and allow the rotator to move towards the distal end of the handheld portion and move the drug vial to the seated position when the trigger portion slides toward the proximal end of the handheld portion.

Abstract
A wearable drug delivery device has a needle assembly and a drug vial arranged side-by-side. This arrangement makes the device compact so that it can be easily worn around a user'"'"'s wrist, for example. When the user triggers the device to inject a dose of medication like epinephrine, in an orchestrated sequence, a first spring drives the needle assembly downward and inserts a needle into the user while connecting the needle assembly to the drug vial. A second spring then delivers the dose from the drug vial through the needle and into the user. Advantageously, the small form factor encourages the user to wear the device and have lifesaving medication at the ready.
