  • Patent number: 11904153
    Abstract: Described is a medicament delivery device comprising a case adapted to hold a container with a medicament and having a needle, a needle sleeve telescopically coupled to the case and having a first extended position relative to the case in which the needle is covered, a retracted position relative to the case in which the needle is exposed, and a second extended position relative to the case in which the needle is covered, a first indicia disposed on the needle sleeve which is visible in the first extended position and the second extended position, and a second indicia disposed on the needle sleeve and not visible in the first extended position and visible the second extended position.

  • Patent number: 11129945
    Abstract: An auto-injector device comprising an injector body having a proximal end and a distal end; a syringe received in the injector body; a needle disposed in a first end of the syringe to extend toward an opening in the distal end of the injector body; and a sealing element disposed at the distal end of the injector body for making a seal against a patient's skin. The auto-injector is configured to generate a reduced pressure to draw the auto-injector device against the patient's skin. The auto-injector device comprises a pressure-reducing mechanism configured to generate the reduced pressure within the injector body during an injection process. The pressure reducing mechanism comprises a moveable member configured such that movement of the moveable member from a first position to a second position enlarges a closed volume within the injector body to generate the reduced pressure within the closed volume.
