A plunger stopper (12) configured for attachment with a plunger rod (14) for use with a within a syringe barrel for high dose accuracy drug delivery. The stopper having a first portion (40) formed from a first material and a second portion (42) formed from a second material, wherein the second material has a greater rigidity than the first material and wherein the second portion is configured to be attached to a plunger rod. The second material can be in the form of an insert (44) which functions to reduce the amount of distortion of the stopper during use, reduce air bubble size variation from fill to fill, maintain a seal with the inner wall of the syringe barrel with lower contact pressure in a resting state and reduce the amount of hysteresis of the stopper. The stopper can be adapted for use with infusers, pens, and other types of auto-injectors.

Aspects of the present disclosure disclose a system for delivering medication. In one aspect, the disclosure is directed a kit that includes a medical dispensing device with a label with a series of zones of varying widths, with each of the zones corresponding to a pre-determined volumetric dose of the drug that is correlated to one of the physical characteristics of a patient. In one specific example, the label is further affixed to the medicine dispensing device such that the smallest dose of the drug to be administered corresponds to a first zone that is proximate an opening through which the drug is to be dispensed.

A drive assembly for a drug delivery system includes a plunger member configured to engage and move a stopper within a container, with the plunger member having a first position and a second position axially spaced from the first position, a leadscrew configured to move the plunger member from the first position to the second position, and a biasing member configured to bias the leadscrew in a rotational direction, where rotational movement of the leadscrew is configured to move the plunger member from the first position to the second position.

A needle injection array can comprise a plurality of needles that are fluidly interconnected via a fluid manifold. The fluid manifold can be configured to direct fluid from a syringe to arrive at tips of the needles approximately simultaneously. The fluid manifold also be configured to provide approximately equal dosage or fluid volume through each of the needles to an injection site.

Various embodiments relate to a resetting mechanism for resetting a screw spindle of a drug delivery device including a driving element including two opposite driving pillars, connected to a sidewall and disposed in a chamber, a limiting element, movably engaged with the driving element, and two opposite clamping elements, movably disposed on two sides of the screw spindle, each of the clamping elements including a sliding base wherein the sliding base has a guide rail and a recess and a clamping jaw, connected to the sliding base and disposed in the chamber, wherein the opposite driving pillars slide in the guide rails along with the movement of the driving element, when the driving element moves toward the limiting element, the driving pillars drive the two clamping elements to move toward the screw spindle to make the two clamping jaws clamp the screw spindle and when the driving element moves away from the limiting element, the driving pillars drive the two clamping elements to move away from the screw spindle to make the two clamping jaws release the screw spindle.

Methods, systems, and devices are disclosed for administering a medicament to a patient. In one aspect, a system includes an injection pen device in wireless communication with a mobile communication device. The injection pen device includes a housing including a chamber to encase a cartridge containing medicine, a dose setting and dispensing mechanism to set the mechanism to dispense a particular dose of the medicine from the loaded cartridge, a sensor unit to detect a dispensed dose based on positions and/or movements of the dose setting and dispensing mechanism, and an electronics unit in communication with the sensor unit to process the detected dispensed dose and time data associated with a dispensing event and to wirelessly transmit the dose data to a user's device. The mobile communication device provides a software application to provide the user with health information using the processed dose data.

An electronics device provided for a drug delivery device or a drug delivery add-on device is disclosed, wherein the drug delivery device or the drug delivery add-on device comprises a dose measurement function and a data transmission function. The electronics device comprises at least one first controller unit being provided for controlling dose related functions of the drug delivery device or drug delivery add-on device and for data processing functions comprising one or more first numerical calculations with dose related data, and at least one second controller unit being provided for data processing functions comprising one or more second numerical calculations with dose related data having a higher complexity than the first numerical calculations and communication functions, wherein the at least one first controller unit is designed for using less power than the at least one second controller unit.

The present disclosure refers to an electronic module for a drug delivery device comprising a dose setting and drive mechanism, configured to perform a dose setting operation for setting a dose to be delivered by the drug delivery device and a dose delivery operation for delivering the set dose. The electronic module comprises at least one processor, a sensor arrangement connected to the at least one processor and operable to generate measurement data indicative of the dose setting operation and/or the dose delivery operation, a first communication unit with a wireless communication interface connected to the at least one processor and operable to establish an encrypted wireless communication with a second communication unit of another device and to transfer data to said other device, a memory for storing measurement data, and a power source connected to the at least one processor.

Described is an electronics assembly with pressure or force sensing capabilities for use in a drug delivery device. The electronics assembly includes a processor, a sensor arranged to measure the force applied by a drive mechanism to drive a medicament from a cartridge, a wireless module to which an external device can be paired, a power module arranged to supply power to the assembly, and memory storing instructions for the processor to perform. The instructions include receiving a measurement signal during the drug delivery operation, and determining if the dose of the medicament was expelled from the drug delivery device based on the received measurement signal.
