Abstract: An auto-injection device including a housing, cartridge, needle, and needle cover. The housing includes longitudinally extending flexible arms. The cartridge moves relative to the housing and contains fluid medicament. The needle is at a proximal end of the device. The needle cover has openings along the longitudinal direction and moves between a first position, a second position, and a third position, wherein the needle is unexposed in the first and third positions and in the second position the needle is exposed. The needle cover is biased towards the third position. An abutment on the at least one longitudinally extending arm of the housing is receivable within the at least one opening along the longitudinal direction of the needle cover when the needle cover is biased into the third position.

Abstract: An auto-injection device for delivery of a fluid medicament is provided. The device includes an ampoule having a fluid medicament contained between first and second stoppers; a first sleeve movable along the longitudinal direction relative to the ampoule; a second sleeve at least partially surrounding the ampoule and movable along the longitudinal direction relative to the ampoule; and a needle. The first sleeve is movable along the longitudinal direction relative to the second sleeve and the ampoule between a first position and a second position. The needle is unexposed in the first position but exposed along the longitudinal direction in the second position. The second sleeve is also movable along the longitudinal direction relative to the ampoule between a first position and a second position. The needle is fluidly isolated from the medicament in the first position and is in fluid communication with the medicament in the second position.
