摘要： 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.

摘要： 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.

摘要： 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.

摘要： Embodiments of the present disclosure relate to techniques, processes, devices or systems for automating fluid delivery without the use of an external interface device. In one approach, a wearable drug delivery device may include a reservoir configured to store a liquid drug, a pump mechanism coupled to the reservoir and operable to expel the liquid drug from the reservoir, and a mechanical triggering device engageable by a user. The mechanical triggering device is operable to change between a first configuration and a second configuration to control deployment of a needle to deliver the liquid drug into a patient.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Embodiments of the present disclosure relate to techniques, processes, devices or systems including a floating microneedle assembly decoupled from the device and protected by a pump housing. In one approach, a wearable drug delivery device may include a pump housing including a base attachable to a user, and a microneedle assembly coupled to a cannula. The microneedle assembly may be operable to deliver a liquid drug to the user, wherein the microneedle assembly comprises a carrier positioned proximate an opening of the base, and wherein the carrier comprises a plurality of microneedles operable to extend through the opening of the base to penetrate a skin of the user.
