Abstract: The autoinjector has a proximal end and, a longitudinal axis A, and a housing configured to receive a medical container having a barrel defining a reservoir for containing a medical product, and said barrel having a distal end provided with a needle and an opened proximal end configured to receive a plunger rod for pushing a stopper arranged inside the barrel. A needle cover is coupled to and movable with respect to said housing between a first extended position, a retracted position, and a second extended position wherein the needle cover moves back in the distal direction to shield the needle. An injection mechanism is configured to move the plunger rod distally inside the barrel in order to expel the medical product contained inside the barrel. A holder is movable with respect to the housing between a passive position wherein the holder does not trigger the injection mechanism and an active position wherein the holder triggers the injection mechanism.

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: Provided herein is an end-of-dose indicator for a medical injection device including a housing having a proximal end, a distal end, and a sidewall therebetween defining an interior, the housing configured to be secured to a proximal end of a medical injection device. The indicator also includes a switch arranged within the housing interior and having an open position and a closed position, a circuit, and one or more indicators in electrical communication with the circuit. When in the closed position, the switch triggers the circuit to activate the indicator.

Abstract: Provided herein is a safety syringe including a syringe having a barrel having a proximal end, a distal end, and a sidewall therebetween defining an interior, a needle arranged at the distal end of the barrel, and a plunger arranged at the proximal end of the barrel, and a safety subassembly, having a support body having a proximal end, a distal end, and a sidewall therebetween defining an interior, the syringe received within the support body interior, a plurality of finger grips arranged at the proximal end of the support body, and a needle cover arranged at the distal end of the support body and biased distally relative thereto, the needle cover having a proximal end, a distal end configured to contact an injection site of a user, and a sidewall therebetween, the needle cover configured to slide telescopically relative to the support body.

Abstract: Provided herein is a housing assembly for a drug delivery device, including a first housing part having a first proximal end comprising a first engagement portion and a second engagement portion, a first distal end, and a first sidewall therebetween defining a first longitudinal axis and a first interior, the first sidewall comprising one or more windows therethrough; and a second housing part having a second proximal end, a second distal end comprising a third engagement portion and a fourth engagement portion, and a second sidewall therebetween defining a second longitudinal axis and a second interior.

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, comprising configured to prevent movement of the needle cover to the use position.
