Abstract: A drug delivery device assembly is provided, including an injector housing, a needle assembly, a drive assembly, and an alignment accessory. The injector housing may include a body with a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end. The needle assembly is at least partially disposed within the body and may include a syringe barrel containing a medicament and a needle or a cannula. The drive assembly is at least partially disposed within the body and operably coupled with the needle assembly to urge the medicament through the needle or cannula during an injection sequence. The needle or cannula is configured to pierce a patient's skin at an injection site. The alignment accessory includes an accessory body configured to be selectively coupled with the injector housing and an alignment aid configured to aid alignment of the accessory body with respect to the patient's skin at the injection site.

Abstract: A drug delivery device including a housing, a drug storage container, and a removable cap is provided. The removable cap may be configured to be removably coupled with the housing such that the removable cap has a storage position where the removable cap is coupled with the housing and at least partially covering an opening in the housing and a removed position where the removable cap is not coupled with the housing. The removable cap may include an outer portion, an inner portion, and a gap separating at least a portion of the inner portion and at least a portion of the outer portion such that the at least a portion of the outer portion is allowed to bend with respect to the at least a portion of the inner portion if the at least a portion of the outer portion is subjected to an external force. Additionally or alternatively, the removable cap may be configured such that an external force applied to the removable cap induces at least one bending moment in a proximal end and/or a distal end of the removable cap.
