An add-on device adapted to be releasably mounted on a drug delivery device, the add-on device comprising an outer assembly with an add-on dose setting member adapted to be coupled to the outer housing of a pen housing, as well as an inner assembly engaging the pen dose setting member and being in rotational engagement with the add-on dose setting member during dose setting. The invention addresses the issue of preventing transfer of movement from the add-on dose setting member to the inner assembly during dose expelling, which in accordance with the invention is realized by rotationally de-coupling the inner and outer assembly during dose expelling.

An electronic system for a drug delivery device including a dose setting and drive mechanism, a communication unit, an electronic control unit, and an electrical use detection. The dose setting and drive mechanism includes a first member and a second member that move relative to each other at least in the dose delivery operation and/or in the dose setting operation of the drug delivery device. The electronic system has a first state in which the communication unit is not activated and a second state in which the communication unit is activated. The electrical use detection unit is configured to generate a first signal indicative that the user has commenced or finished the relative movement between the first member and the second member. The electronic control unit is configured to switch the electronic system from the first state into the second state in response to the first signal.

The present invention relates to a drug delivery device for setting and dispensing of a dose of a medicament is presented comprising a housing to accommodate a cartridge filled with the medicament, an electrically operated drive mechanism to be operably engaged with the cartridge to expel a predefined dose of the medicament from the cartridge, and at least one dose element displaceably arranged relative to the housing to set and/or to dispense the dose of the medicament, wherein the dose element and the drive mechanism are mechanically decoupled from each other.

The disclosure relates to a sensor arrangement for an injection device to determine an axial position of at least one device component of the injection device inside a housing of the injection device. The sensor arrangement includes an elongated member located inside the housing, extending in an axial direction and having at least a first section and a second section of different magnetization. The first and second sections are separated in the axial direction. The sensor arrangement also includes at least one magnetic sensor element attached to the housing to detect the axial position of at least one of the first and second sections.

A method of manufacturing a pen drug delivery device comprising the steps of (i) providing a drug delivery device comprising a dose indicator member adapted to move relative to a housing during dose setting and dose expelling corresponding to an axis of rotation, the indicator member having an initial position corresponding to no dose amount being set, (ii) arranging the indicator member in the initial rotational position, and (iii) providing on the housing and on the indicator member respectively a pair of zero markers having a predetermined rotational offset. By this arrangement the issue of finding the correct initial (zero) rotational position of the indicator member is addressed by providing corresponding and rotationally paired zero markings on the pen housing and the indicator member after the pen device has been assembled, this allowing the “true” initial position to be detected by image capture and subsequent image analysis.

A dropping pipette-type cosmetic container includes a container body having a discharge port formed on one side thereof, a downward movement limiting member coupled to the other side of the container body, a pressing button rotatably coupled to the downward movement limiting member and configured to move downward by pressurization, and an elastic member for elastically supporting the pressing button; the downward movement limiting member has multiple main grooves formed thereon at different depths and has auxiliary grooves formed thereon so as to have the same depths as those of respective main grooves, which have different depths, and to constitute pairs therewith; main protrusions to be inserted into the main grooves and auxiliary protrusions to be inserted into the auxiliary grooves are formed on the pressing button so as to correspond to each other.

A drive-control system for an injection device for delivering settable doses of a pharmaceutical substance contained in a cartridge, including a tubular housing body having a longitudinal axis, a proximal end and a distal end connectable to the cartridge enclosure, a helical spring contained in the housing body and a piston rod moveable towards the distal end and blocked in translation towards the proximal end. The housing body includes a control sleeve on which the spring is mounted, which rotatable around the axis, and a setting sleeve translatable along the axis. Rotation of the control sleeve in a first direction combined with compression of the spring causes the setting sleeve to be translated towards the proximal end of the housing body, and extension of the spring causes the setting sleeve to be translated towards the distal end of the housing body and the control sleeve to be rotated in a second direction and the piston rod to be pushed towards the outside of the housing body.

A medicament delivery device configured to provide a variable single dose of medicament is disclosed. The medicament delivery device includes a main body and a syringe arranged in the main body, wherein the syringe comprises a medicament. The medicament delivery device further includes a removable cap and a plunger rod operatively arranged to eject the medicament through a delivery member i.e. an injection needle attached to the syringe. Still further, the medicament delivery device includes a tubular member coupled to the plunger rod. The tubular member is configured to rotate during removing of the removable cap, and the rotation releases the plunger rod thereby allowing the plunger rod to travel a predetermined distance so as to prime the medicament delivery device.

An electronic device comprising: a housing for attachment to an injection device; a first sensor assembly comprising a first coil and two magnets of opposite polarity, wherein the first coil is configured to provide a first voltage pulse as a first Wiegand wire of the injection device moves from a first position proximate to one of the magnets of the first sensor assembly to a second position proximate to the other magnet of the first sensor assembly; and one or more processors configured to enter an enabled state from a sleep state after receiving the first voltage pulse from the first coil.

An electronically-controlled capturing system for capturing data representing an amount of a drug expelled or discharged from a drug reservoir includes an electronic circuit including an electric energy unit, a processing unit operable by electric power obtained from the electric energy unit and operable to acquire data, and an electronic storage unit connected to the processing unit and configured to store the acquired data. The processing unit is operable to write the acquired data in the storage unit and is operable to read and provide the stored data from the electronic storage unit. The capturing system also includes a data reading disabling unit operably connected to the processing unit , the electronic storage unit and/or the electric energy unit. The data reading disabling unit is switchable into an activated state, in which the data reading disabling unit persistently prevents readout or providing of stored data from the electronic storage unit.
