The present disclosure relates to a method of pairing an electronic data logging device of a drug delivery device with an external electronic device and to a respective drug delivery device. The drug delivery device comprises a housing configured to accommodate the medicament and to receive and/or mechanically engage with the electronic data logging device. The drug delivery device further comprises a first device component and a second device component. The first device component is movable relative to the second device component from a first positional state to a second positional state. The first device component comprises a first outer surface, and the second device component comprises a second outer surface. At least one of the first outer surface and the second outer surface comprises a first code portion of a pairing code for establishing a communication link between the electronic data logging device and an external electronic device.

Medication delivery devices are provided having a dose delivery sensing capability. A sensed element is attached to a dose setting member of the device. The sensed element includes surface features radially-spaced from one another. A rotational sensor is attached to an actuator of the device. The rotational sensor includes a movable element that is contactable against the surface features. The rotational sensor is configured to generate a signal in response to the movement of the movable element over the surface features during their rotation. A controller is operatively coupled to the rotational sensor, and in response to receiving the generated signal, the controller is configured to determine a number of the surface features passing the movable element of the rotational sensor during dose delivery. The number can be associated with an amount of dose delivered. Sensing can be provided in a module or integrated in device.

The present disclosure relates to medicament injection devices. An injection device includes: a movable dosage programming component comprising a rotary encoder system having a predefined angular periodicity, a sensor arrangement including a first optical sensor configured to detect movement of the movable dosage programming component relative to the sensor arrangement during dosing of a medicament, wherein the first optical sensor is configured to operate in a strobe-sampling mode at a first frequency, a second optical sensor configured to detect movement of the rotary encoder system relative to the second optical sensor wherein the second optical sensor is configured to operate in a strobe-sampling mode at a second frequency lower than the first frequency, and a processor arrangement configured to, based on the detected movement, determine a medicament dosage administered by the injection device.

A supplemental device for attachment to an injection device, the supplemental device comprising: a housing; an electromechanical switch arrangement having an open state and a closed state, the electromechanical switch arrangement comprising a protrusion configured to contact a surface of the injection device while the supplemental device is attached to the injection device; a dose dialled detector operable to detect a dose of medicament dialled into the attached injection device; and a processor arrangement configured to: monitor the detected dose of medicament dialled into the attached injection device; detect a change in the state of the electromechanical switch arrangement; and change a display output of the supplemental device when a change in the state of the electromechanical switch arrangement is detected while a zero dose is dialled into the attached injection device.

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.

A medication injecting apparatus has a cartridge housing and a drive housing that is threadedly connected to the cartridge housing for axial displacement relative to one another. The drive housing has a helical-shaped passage and a flexible drive member is slidingly disposed within the helical-shaped passage and extends axially outwardly therefrom toward the cartridge housing. The flexible drive member is movable in the axial direction relative to the drive housing during dose setting and is axially fixed relative to the drive housing during injecting. A clutch has an engaged position and a disengaged position. The flexible drive member is axially fixed relative to the drive housing when the clutch is in the engaged position and the flexible drive member is movable relative to the drive housing when the clutch is in the disengaged position.

A drug injection device includes a last dose setting having a main drive pin, a drive wheel, a driven wheel, an abutment element fixedly coupled to, or integrally formed with, the driven wheel. The drive wheel has a rotation axis parallel to a longitudinal axis and is configured to be driven about the longitudinal axis by a knob and to be periodically driven in rotation about the rotation axis by the main drive pin, during a drug dose setting. The driven wheel has a second rotation axis parallel or coaxial to said longitudinal axis and is configured to be periodically driven about the longitudinal axis by the drive wheel. The abutment element is configured to prevent the rotation of the drive wheel about the longitudinal axis when the knob has made a predetermined number of full and/or partial rotations about the longitudinal axis correlated to the predetermined drug volume.

A drug delivery device is provided comprising a dose setting mechanism having a spindle and a cartridge holder coupled to the dose setting mechanism. The cartridge holder comprising a cartridge having a movable bung at one end of the cartridge. The cartridge holder must be rotated before a dose may set with the dose setting mechanism.

A dose setting mechanism for a drug delivery device. The mechanism may comprise a drug delivery device housing. A dose dial component is positioned in the housing and rotatable during dose setting and dose delivery. A split threaded insert is in threaded engagement with the dose dial component. The insert can transform from a first configuration to a second configuration when the dose dial component is rotated. In one dose setting mechanism arrangement, the first configuration may comprise a first open configuration and the second configuration may comprise a second closed configuration.

Systems, devices, and techniques are disclosed for administering and tracking medicine to patients and providing health management capabilities for patients and caregivers. In some aspects, a system includes an injection pen device in communication with a mobile communication device having a software application to determine a recommended dose based on prior dose data, analyte data, and nutrient data and to generate a report illustrative of a relationship between the medicine data, the health data, and the contextual data.
