  • Device for the automatic injection of two doses of a medicament
    Patent number: 8961463
    Abstract: A two-dose autoinjector for a medicament wherein the locking and releasing of the drive spring of the autoinjector is controlled through stepped guides with ramps for two successive slidings of slides operated by the spring and connected with the syringe and plunger. The guides and the slides are pivotable relative to one another and the sliding direction, while the syringe can only slide axially. To enable or disable the sliding of the slides within the guides an angularly angularly mobile arming member is provided formed with a guide track substantially equal to that of the stationary member where the guides are formed.
