Abstract: A tool for removing a cap from a medical injection device comprising a body and a needle extending distally from the body, the cap covering the needle, the tool being characterized in that it comprises a pair of opposite jaws connected by an elastic interface, each jaw comprising: a distal portion forming a distal clamp configured to surround at least a part of the cap; and a proximal portion forming a proximal clamp configured to be removably axially fixed to a body of the medical injection device, the elastic interface forming a fulcrum located between the distal and proximal portions such that a pinching force exerted radially inwardly onto the distal portion of the jaws causes the proximal portion of the jaws to expand radially outwardly.

Abstract: Provided herein is a subassembly for a drug delivery device, including a housing, a displaceable needle cover having a distal end having a flange, the needle cover being received within the housing and configured to have a pre-use position in which the needle cover extends from the housing and a use position in which the needle cover is at least partially displaced into the housing. Displacement of the needle cover into the housing actuates the drug delivery device. The subassembly further includes a cap assembly including a push back element operatively received within the retainer, wherein the push back element is configured to push the retainer in a proximal direction.

Abstract: Provided herein is a subassembly for a drug delivery device, including a housing defining an interior, the housing including at least one opening therethrough, a plunger rod having a proximal end and a distal end, a drive member received in the housing interior and configured to displace the plunger rod distally, a plunger rod follower having a proximal end and a distal end, the distal end of the plunger rod follower configured to couple with the proximal end of the plunger rod, and an indicator having one or more resiliently-biased arms having a protrusion thereon, wherein the protrusion is configured to be received at least partially within the opening in the housing following activation of the drug delivery device.

Abstract: The shell is intended to receive an injection system comprising a syringe received in a safety device which has: a body receiving the syringe; a shield movable relative to the body, for covering a needle; finger flanges extending outwardly. The shell comprises a tubular housing receiving a distal portion of the safety device and a casing receiving the finger flange, and further comprising: several snap features which flex outwardly during insertion of the finger flange in the casing, the finger flange being inserted distally from a distal face of the snap feature in the mounted position; and a protrusion located distally from each distal face, which exerts an inward biasing force on the finger flange in the mounted position.
