Abstract
A wearable drug delivery device that can deliver a liquid drug stored in a container to a patient is provided. The container can be a prefilled cartridge that can be loaded into the drug delivery device by the patient or that can be preloaded within the drug delivery device when provided to the patient. A sealed end of the container is pierced to couple the stored liquid drug to a needle conduit that is coupled to a needle insertion component that provides access to the patient. A drive system of the drug delivery device can expel the liquid drug from the cartridge to the patient through the needle conduit. The drive system can be controlled to provide the liquid drug to the patient in a single dose or over multiple doses.
