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.

Drug delivery device cassette

An apparatus for delivering a pharmaceutical liquid to a patient includes an outer casing; a needle cassette housed in the casing and containing a plurality of mutually parallel drug injection needles; a drug cartridge housed in the casing, containing a liquid and including a sealable aperture for accessing the liquid; a direct drive assembly housed in the casing and engageable with the drug cartridge to expel a measured dose of the liquid through the aperture; a lifter assembly housed in the casing and engageable with the needle cassette to drive one of the plurality of needles partially out of the casing and into a patient while also accessing the liquid in the drug cartridge through the scalable aperture, and thereafter to withdraw the needle from the patient while halting access of the liquid through the sealable aperture after the measured dose of the liquid has been administered through the needle; motor means in the casing for driving the direct drive assembly and the lifter assembly; computer means for activating the direct drive assembly and the lifter assembly; and a control panel for enabling a user to activate the apparatus.
