摘要： A needle assembly configured to be part of a drug delivery device comprises a plurality of extendable and retractable needles. The needles are fluidly coupled by a flexible connector, which is configured to maintain fluid connection between the needles throughout their movement. When the needles are extended, a first needle pierces a patient's skin, and a second needle pierces a septum of a drug container to deliver a medication. Once the medication has been delivered, the needles may then retract within a needle assembly housing. The needle assembly may also be part of a partially disposable drug delivery device and may be used with multiple different drug cartridges. Multiple embodiments of the needle assembly are disclosed.

摘要： A needle assembly configured to be part of a drug delivery device comprises a plurality of extendable and retractable needles. The needles are fluidly coupled when extended, and fluidly decoupled when retracted. When the needles are extended, a first needle pierces a patient's skin, and a second needle pierces a septum of a drug cartridge to deliver a medication. Once the medication has been delivered, the needles may then retract within a needle assembly housing. The needle assembly may also be part of a partially disposable drug delivery device and may be used with multiple different drug cartridges. Multiple embodiments of the needle assembly are disclosed.

摘要： A drug delivery device may include a cassette with a needle assembly and a cartridge. The cassette is configured to couple and decouple from a reusable module. The device may also comprise an orientation mechanism to orient the cassette in relation to another device, such as a reusable housing. The device may comprise an extendable and retractable needle assembly. The cassette configuration is adapted to have a stopper with a short travel (no more than 14 mm) to deliver 1 mL of medication. The cassette may have a ratio of height to diameter from 2:1 to 1:1. The cassette may include a pair of drivable interfaces for being driven to actuate the stopper to expel medication and to drive the needle assembly between a retracted and extended configuration for controlled fluid communication between the needle and reservoir.
