Medicament delivery device and medicament delivery assembly

Abstract

The present disclosure provides a medicament delivery device for accommodating a medicament container. The medicament delivery device comprises a base unit with a housing extending along a proximodistal axis and a drive unit arranged to be subject to an expelling movement relative to the base unit into a proximal direction, to act on the medicament container for expelling a medicament. The medicament delivery device further comprises a signal member extending longitudinally and being configured to interact with the drive unit and the base unit to be displaced towards distally upon completion of the expelling movement, and to thereby generate a confirmation signal. One of the signal member and of the drive unit comprises a feedback structure extending along the axial direction and comprising a plurality of indentations and/or protrusions The other one of the signal member and of the drive unit comprises an engaging structure for interacting with the feedback structure. The expelling movement causes the engaging structure to slide along the feedback structure and to thereby sequentially engage a plurality of the indentations and/or protrusions to cause a sequence of feedback signals.
