A wearable drug delivery device that can deliver a liquid drug stored in a container to a patient is provided. The container can be a prefilled cartridge that can be loaded into the drug delivery device by the patient or that can be preloaded within the drug delivery device when provided to the patient. A sealed end of the container is pierced to couple the stored liquid drug to a needle conduit that is coupled to a needle insertion component that provides access to the patient. A drive system of the drug delivery device can expel the liquid drug from the cartridge to the patient through the needle conduit. The drive system can be controlled to provide the liquid drug to the patient in a single dose or over multiple doses.

On-body interlock for drug delivery device

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.

Linear shuttle pump for drug delivery

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.

Needle mechanism module for drug delivery device

Drive systems for a drug delivery device are provided. The drive systems can be positioned within a container that stores a liquid drug to be delivered to a user. The drive systems can be coupled to a plunger positioned within the container. The drive systems can be incrementally advanced to drive the plunger further into the container, thereby expelling a portion of the stored liquid drug from the container for delivery to the user. The container can be any type of container including a pre-filled, standardized drug cartridge. The drive systems and container can be components of a wearable drug delivery device.

Drug cartridge with drive system

Drug delivery systems with reduced hold-up volumes are provided. The drug delivery systems include a cartridge configured to hold a liquid drug. A cartridge stopper is positioned in a first portion of the cartridge. A needle guide component is positioned within the cartridge stopper. A needle is positioned within a central opening of the needle guide. A plunger is positioned in a second portion of the cartridge. The plunger includes a fluid path pocket facing and aligned with the central opening of the needle guide component. The plunger is driven toward the cartridge stopper to expel the liquid drug from the cartridge through the needle. An end of the needle can be positioned within the fluid path pocket when the plunger is pushed against the cartridge stopper, ensuring that only a small volume of the liquid drug remains in the cartridge when delivery of the liquid drug is completed.

Cartridge hold-up volume reduction

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.

Single dose drug delivery device

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.

Needle insertion mechanisms for drug containers

Ratchet-based drive systems for more reliable and safer drug delivery are provided. The ratchet-based drive systems restrict angular movement and/or linear movement of components that cause a plunger to expel a liquid drug from a drug container. Movement of the components can be restricted to correspond to a predetermined or desired portion of the liquid drug. In the case that control of the drive system is lost or fails, the maximum amount of drug that could be delivered is limited to a known amount, thereby reducing the likelihood of an overdose.

Ratchet drive for on body delivery system

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.
