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 between a retracted position and an extended position for piercing into a subjects skin.
Claims27
A drug delivery device, comprising:
- a needle assembly including a needle carrier, a needle hub moveable within the needle carrier, and a needle coupled to the needle hub;
- and
- a drug device having a needle drive comprising a motor, the needle carrier coupleable to the drug device to position a proximal end of the needle inserted through a septum in fluid communication within a container of the drug delivery device;
- and
- an actuator configured to activate the needle drive 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.

A drug delivery device, comprising:
- a needle assembly including a needle carrier, a needle hub moveable within the needle carrier, a needle coupled to the needle hub, a cam within the needle carrier, the cam having a driven gear and a drive surface engageable with the needle hub;
- and
- a drug device having a needle drive, the needle carrier coupleable to the drug device to position a proximal end of the needle inserted through a septum in fluid communication within a container of the drug delivery device;
- and
- an actuator configured to activate the needle drive to rotate the driven gear and the cam, in response to the rotation of the cam, the drive surface engages the needle hub such that the needle hub is moved distally from a retracted needle hub position to an extended needle hub position and the needle is moved distally relative to the septum from a retracted needle position to an extended needle position.

A drug delivery device, comprising:
- a needle assembly including a needle carrier, a needle hub moveable within the needle carrier, a needle coupled to the needle hub, a driven gear within the needle carrier;
- and
- a drug device having a needle drive gear, the needle assembly coupleable to the drug device to mesh the needle drive gear with the driven gear;
- and
- wherein, in response to the rotation of the drive gear, the driven gear is rotated in a first direction and the needle hub is moved from a retracted needle hub position to an extended needle hub position and the needle is moved relative to the needle carrier from a retracted needle position to an extended needle position.
