A drive assembly for a medication delivery device is provided, comprising a piston rod which is movable from a start position to an end position for medication delivery and resettable from the end position to the start position. The drive assembly further comprises a guide member, being in engagement with the piston rod, and an impeding element for impeding a movement of the guide member during a reset of the piston rod and thereby impeding the reset of the piston rod. Furthermore, a medication delivery device comprising the drive assembly is disclosed.

Drive assembly for a medication delivery device and medication delivery device comprising a drive assembly

The present invention relates to an assembly for a drug delivery device comprising a dispensing container and a reservoir container for holding a fluid medicinal product, wherein the dispensing container and the reservoir container are connected to one another and are in fluid communication, and wherein the dispensing container is squeezable for dispensing a dose of the fluid medicinal product from the dispensing container, the dispensing container being refillable with the fluid medicinal product from the reservoir container.

Assembly for use in a drug delivery device

The invention relates to a pump unit (), replaceably attachable to a reusable backend () of an injection arrangement () for delivering a liquid medicament, the pump unit () comprising a medicament inlet (), a medicament outlet () and a peristaltic pump for delivering the liquid medicament from the inlet () to the outlet (), the peristaltic pump comprising a pump rotor () and a pump hose (), the pump hose () partially arranged around the pump rotor (), the pump rotor () having protrusions () for engaging the pump hose (), wherein a fixing side () of the pump unit () facing a reusable backend () when attached has a recess () in the shape of a circular arc for allowing a correspondingly shaped stop () protruding from the reusable backend () to enter into the pump unit () so as to support the pump hose () from an outer side opposite the pump rotor () thus allowing the protrusions () to locally squeeze the pump hose () against the stop () when attached to the reusable backend ().

Injection arrangement

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).

Arrangement for determining a longitudinal position of a stopper

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.

Drug delivery device and use of a rotatable roll in a drug delivery device

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.
