Abstract: The invention refers to an arrangement and a method for determining a longitudinal position of a stopper for sealing a compartment of a translucent medicament container for a liquid medicament (M). The arrangement comprises a circular light source and a photo sensitive sensor, wherein either the light source or the sensor is laterally arrangeable next to the medicament container extending over at least part of the length of the medicament container, and wherein the respective other of the light source and the sensor is arrangeable in a circular manner around a head of the medicament container. The light source is arranged to emit light into the medicament container. The light is scattered by the medicament or medicament container and detected by the sensor. The sensor is connected to a processor unit for detecting the position of the stopper).

Abstract: A drug delivery device is provided which comprises a housing, a dispensing end for dispensing a drug from the drug delivery device, a flexible container for holding the drug, the flexible container comprising an outlet, the outlet being connected to the dispensing end, and a squeezing member for squeezing the flexible container, wherein, for dispensing a dose of the drug from the drug delivery device, the squeezing member and the flexible container are axially displaceable relative to one another, the squeezing member rotating with respect to the housing during the relative axial displacement and squeezing the flexible container, thereby urging the dose of the drug from the container through the outlet. Furthermore, using a rotatable roll in a drug delivery device is described.

Abstract: The present invention relates to a device for injecting a pharmaceutical into the human or animal body by means of a simply and quickly exchangeable motorized pump head.

Abstract: A fluid drug delivery system comprises a rigid shell having an inner sidewall, an opening and a passage as well as a collapsible cartridge with a distal end and a proximal end. The collapsible cartridge is arranged within the shell with its distal end being closer to the opening than the proximal end. It further comprises a first portion including the proximal end and a second portion including the distal end. The second portion is recoilable from the inner sidewall to urge a fluid, which comprises a drug and is contained in the collapsible cartridge, to the passage of the rigid shell. Further, the rigid shell and the collapsible cartridge are co-extruded.
