In one aspect the present disclosure refers to a supplementary device for a manually operable injection device, the supplementary device comprising:

Supplementary device for an injection device

The disclosure relates to a drug delivery device having a drive unit includes a stator comprising a plurality of coils consecutively arranged in an axial direction, and an armature axially movable within the stator, the armature including a number of magnets and pole shoes consecutively arranged in the axial direction. A respective pole shoe is arranged between respectively neighbouring magnets. At least one axial end of the armature comprises a terminal pole shoe.

Drug delivery device with electromagnetic drive unit

The present disclosure relates in one aspect to a measuring arrangement for measuring a volume occupied by a liquid medium inside a liquid reservoir, the measuring arrangement including a container having an interior volume containing a gas reservoir filled with a gaseous medium and containing a liquid reservoir filled with a liquid medium, wherein the gas reservoir and the liquid reservoir are hermetically separated by an impenetrable separation wall, a volume modulator to induce a volume change of the gas reservoir, a pressure sensor arranged inside the gas reservoir to measure a pressure change of the gaseous medium in response to the volume change of the gas reservoir, and a controller connectable to the pressure sensor, wherein the controller is configured to calculate the volume of the liquid reservoir on the basis of the pressure change and the volume change.

Volume measuring arrangement

In one aspect the present disclosure refers to a measuring arrangement for measuring of a volume change of a liquid medium located inside a liquid reservoir, the measuring arrangement comprising:

The invention relates to a linear actor arrangement, comprising a linear actor with two ends whose distance is variable depending on an energizing of the linear actor, wherein each end is attached to a respective first or second coupling element which engage a coupling surface, wherein the coupling surface and the coupling elements exhibit mating surface structures in such a manner that the coupling elements are prevented from moving in a direction while being allowed to move in an opposite direction.

Linear actor arrangement

An arrangement for determining a position (x) of a stopper relative to a container in a drug delivery device includes an acoustic source configured to emit an acoustic signal and an acoustic sensor configured to detect an acoustic signal, a processing unit for controlling the acoustic source and processing the detected acoustic signal for determining characteristics of the acoustic signal correlated with the position (x) of the stopper. A method for determining a position (x) of a stopper relative to a container in a drug delivery device includes the steps of emitting an acoustic signal from an acoustic source, detecting an acoustic signal caused by the emitted acoustic signal by means of an acoustic sensor, and processing the detected acoustic signal for determining characteristics of the acoustic signal correlated with the position (x) of the stopper by means of a processing unit.

Arrangement and method for determining a stopper position

The invention relates to a drug delivery device, comprising a control unit, a drive unit, a pressurizing medium container arranged to contain a pressurizing liquid, a drug container arranged to contain a drug and a discharge nozzle, wherein the drive unit when controlled and energized by the control unit is arranged to generate a pressure gradient in the pressurizing liquid thereby propagating the pressure to the drug container and at least partially displacing the drug from the drug container through the discharge nozzle, wherein the drive unit is arranged as an electro-osmotic actor.

Drug delivery device

The invention relates to a stopper arrangement for a drug delivery device, comprising a stopper, a linear actor coupled with one end to the stopper and with an opposite end to a coupling arrangement, wherein the stopper arrangement is configured to be disposed within a container of a drug delivery device, wherein a shape and/or material of the stopper and the coupling arrangement are configured such that a first frictional force between the coupling arrangement and the container is lower than a frictional force between the stopper and the container when the linear actor is contracting and that second frictional force between the coupling arrangement and the container is greater than the frictional force between the stopper and the container when the linear actor is expanding.

Stopper arrangement for a drug delivery device

The invention relates to an arrangement for determining a position (x) of a stopper relative to a container in a drug delivery device, comprising an acoustic source configured to emit an acoustic signal and an acoustic sensor configured to detect an acoustic signal, a processing unit for controlling the acoustic source and processing the detected acoustic signal for determining characteristics of the acoustic signal correlated with the position (x) of the stopper. Furthermore, the invention relates to a method for determining a position (x) of a stopper relative to a container in a drug delivery device, the method comprising the steps of emitting an acoustic signal from an acoustic source, detecting an acoustic signal caused by the emitted acoustic signal by means of an acoustic sensor, and processing the detected acoustic signal for determining characteristics of the acoustic signal correlated with the position (x) of the stopper by means of a processing unit.
