Described is a dose tracking mechanism for a drug delivery device, including a moveable component configured to move with respect to a housing during operation of the drug delivery device and an RFID device with an electric circuit having a resonance frequency. The electric circuit includes an antenna configured to transmit a wireless RFID signal at the resonance frequency and an electrical component operatively coupled to the moveable component and configured to modify the resonance frequency based on a position of the moveable component, such that the resonance frequency of the electric circuit is an indication of the position of the moveable component. In some instances, the position of the moveable component indicates a dose set or dispensed from the drug delivery device.

RFID dose tracking mechanism for injection devices

An optical decoding system including an optical sensor integral with or attachable to a housing of a drug delivery device and configured to be directed at first and second rotatable components of a dose setting and dispensing mechanism of the drug delivery device and a processor configured to: (i) cause the optical sensor to capture images of the first and second rotatable components at least at the beginning and end of a medicament dose dispensing process; (ii) determine a rotational position of both the first and second rotatable components in each of the captured images; and (iii) determine from the rotational positions of the first and second rotatable components an amount of medicament delivered by the dose setting and dispensing mechanism of the drug delivery device.

Sensor for use with a drug delivery device

The present disclosure relates to a drug delivery device for setting and injecting of a dose of an injectable medicament, the drug delivery device comprising: an elongated housing extending along a longitudinal axis and having a sidewall with at least a first aperture, at least one number sleeve rotatably supported inside the housing and comprising an outer surface, wherein a first portion of the outer surface is visible through the first aperture and wherein the number sleeve comprises a non-visible code in the region of the first portion.

Drug delivery device with removably attachable sensor device

A drug delivery device comprising a housing body; a piston rod configured to rotate in a rotational direction during dose dispensing under a driving force; and a threaded insert, wherein the piston rod is in threaded engagement with the threaded insert such that during the dose dispensing. the piston rod displaces axially in a distal direction relative to the threaded insert for displacement of a cartridge hung. The threaded insert is movable relative to a stop provided in the housing body and a spring is provided to bias the threaded insert against the stop so that the rotation of the piston rod causes the threaded insert to move away from the stop in response to reaction forces, induced by the cartridge bung into the threaded insert, acting on the piston rod in a proximal direction when the reaction forces exceed a biasing force of the spring.

Drug delivery device

The disclosure provides a dose controlled multi-shot injection device comprising a housing and a dose setting mechanism, wherein the dose setting mechanism includes a drive spring, a rotatable dose setting handle adapted to set a dose of medicament, thereby biasing the drive spring, and a ratchet mechanism for maintaining the drive spring in a biased state against a spring force at a set dose. The ratchet mechanism includes a fixed ratchet element coupled to the housing and having a circumferential teething, a movable flexible ratchet element provided with at least two teethed portions configured to engage the circumferential teething at least pairwise at any one of a plurality of engaging positions, which respectively represent a set dose, and a rotational element coupled to the dose setting handle configured to translate torque from the dose setting handle into a number of forces radially acting on the flexible ratchet element resulting in an elastic deformation of the flexible ratchet element, thereby releasing the engagement between the teethed portion and the circumferential teething.

Dosing mechanism for multi-shot injection device comprising flexible ratchet element

The disclosure relates to a drug delivery device for dispensing a liquid drug through a needle with a proximal and a distal needle tip, comprising
