    Abstract: Injection systems for drug delivery are disclosed. A system may include a container filled or fillable with a drug, a stopper movably disposed in the container, a plunger, an energy source outputting a force, a mechanical linkage operable to transmit the force output by the energy source to the plunger to cause the plunger to act on the stopper to expel the drug from the container, and a trigger member. The system may have pre-injection state where the trigger member inhibits actuation of the mechanical linkage, an injection state where the trigger member permits actuation of the mechanical linkage, and a post-injection state where the plunger is stationarily positioned in an end-of-dose position. The system may be designed to limit the number of components included in various force transmission loops present in the pre-injection, injection, and/or post-injection states.

    Abstract: A robotic inspection platform comprises a robotic arm, an imager, and a controller. The controller causes the robotic arm to retrieve, using its end effector, a container, and to manipulate the container such that the container is sequentially placed in a plurality of orientations while in view of the imager. The controller also causes the imager to capture images, with each of the images being captured while the container is in a respective one of the orientations. The controller also determines one or more attributes of the container, and/or a sample within the container, by analyzing the images using a pattern recognition model and, based on the attribute(s), determines whether the container and/or sample satisfies one or more criteria. If the container and/or sample fails to satisfy the criteria, the controller causes the robotic arm to place the container in an area (e.g., bin) reserved for rejected containers and/or samples.

    Abstract: A testing system for a drug delivery device includes a frame member having first and second ends, a driving member positioned near the frame member, a surrogate syringe barrel operably coupled with the frame member, a flange extender adapted to couple with a portion of the surrogate syringe barrel, and a plunger rod adapted to couple with the flange extender and be at least partially disposed within the surrogate syringe barrel while being movable therein. The driving member is movable in an axial direction between the first end and the second end of the frame member. The plunger rod includes first and second ends and a longitudinal length therebetween, the first end being positioned near a portion of the driving member. The driving member measures a maximum urging force exerted on the plunger rod when moving in the axial direction towards the second end of the frame member.
