Abstract: Systems and methods for monitoring an operational state and/or a fill status of a drug container of a drug delivery device are provided. The drug container can hold a liquid drug. A plunger can be positioned within the drug container. A drive system can advance the plunger to expel the liquid drug from the container. A monitoring system can detect a movement and/or a position of the plunger and/or any component coupled to the plunger. The detection can enable determination of an amount of liquid drug that has been expelled and/or an amount of liquid drug remaining in the drug container. Dosing rates, flow rates, and dosage completion can also be determined.

Abstract: Examples of fluid delivery drive system and/or pump system that creates a vacuum in a fluid line for drawing and expelling fluid are provided. The vacuum may be created by separating two components that are positioned within the sealed fluid line. Once the two components are separated and the fluid is contained within the volume created between the separated components, the two components may be shuttled within the sealed volume. The movement of the two components can seal off an inlet to the fluid line and then open a pathway to an outlet from the fluid line while ensuring the created volume between the two components is maintained constant. The two components can then be moved back together to expel the fluid from the created volume through the outlet for delivery, for example, to a patient. Other examples are disclosed and described.

Abstract: Systems for piercing a septum of a drug delivery device is disclosed. The drug delivery device may include a needle conduit having an end and a drug container having a septum. The septum piercing mechanism may include a needle support operatively coupled to the needle conduit. The septum piercing mechanism may be movable from a first, unactivated configuration to a second, activated configuration. In the unactivated configuration, the septum seals an interior of the drug container from the end of the needle conduit. In the activated configuration, the end of the needle conduit pierces through the septum placing the needle conduit in fluid communication with the drug container. In one embodiment, activation may cause the needle support to move towards the drug container. In one embodiment, the needle support may be moved by a biasing member. Alternatively, in another embodiment, the needle support may be moved by a cam mechanism.

Abstract: A needle mechanism module for automatically inserting a fluid path into a patient for drug delivery is provided. The needle mechanism module can be a component of a wearable drug delivery device. The needle mechanism module can insert a needle and cannula into the patient responsive to activation of the drug delivery device by a user. After insertion, the needle can be automatically retracted, leaving only the cannula in the patient. As a result, discomfort of the user is reduced.

Abstract: Systems, components, and methods are disclosed for withdrawing drug from a liquid drug container and transferring drug to a medical device. One or more components may have keying features so that only the correct liquid drug container and medical device are accessed, making sure the medical device is filled with the correct drug. A syringe needle hub may have keying features corresponding to keying features on a cap on the liquid drug container and on the medical device. An alignment device facilitates easy-to-operate filling of a medical device. The alignment device aligns a liquid drug container over a fill port of the medical device and can include components for moving the liquid drug container into engagement with the medical device and for automatically initiating drug transfer to the medical device. A retractable skirt or needle cover protects the needle and is unlocked only when the skirt or needle cover is close to or touching the medical device.
