Abstract
A drug delivery assembly is used for delivering a medicament to a patient. The assembly includes a main body having a housing and defining a recess, with an actuator associated with the housing. An adhesive pad, configured to attach to a human body surface, is associated with a lower surface of the housing. The assembly also includes a cartridge configured to be at least partially inserted into the recess and having: a cartridge housing, a drug reservoir positioned within the cartridge housing, a stopper movably associated with the drug reservoir, and a needle movably associated with the drug reservoir. The actuator is manipulated to deploy the needle, with the actuator also engaging the cartridge to prevent removal of the cartridge from the recess during drug delivery. A rod of the body engages the stopper to move the stopper and dispense a medicament from the drug reservoir during drug delivery.
