Abstract
Drug delivery devices are provided having a needle assembly portion and a drug device portion, where the needle assembly portion is removably coupleable to the drug device portion. In some embodiments, the needle of the needle assembly may be moveable from a retracted position to an extended position for piercing into a subjects skin. In some embodiments, the needle may also be moveable back to a retracted position.
Claims19
A drug delivery device, comprising:
- a needle assembly including a needle carrier, a needle hub moveable relative to the needle carrier, the carrier drive element comprising an axially compressible spring, and a needle coupled to the needle hub;
- a drug device having a container with a septum disposed at a container end opening and a carrier drive element, the needle carrier removably coupleable to the drug device;
- and
- a deployment trigger coupled to a distal end of the needle carrier, wherein the deployment trigger is configured to activate the carrier drive element to move the needle hub distally from a retracted needle hub position to an extended needle hub position and to move the needle distally relative to the septum from a retracted needle position to an extended needle position,
- wherein in response to coupling of the needle assembly to the drug device said spring is loaded, and
- wherein the deployment trigger is actuated by force applied in a proximal direction against the deployment trigger to unload said spring and to move the needle to the extended needle position.
