Frontloaded Drug Delivery Device with Dynamic Axial Stop Feature

摘要

Drug delivery device adapted to receive a cartridge and comprising a housing, a front-loaded cartridge holder adapted to receive and hold a cartridge in a loaded position, and stop means adapted to engage a proximal surface of a received cartridge The stop means is actuatable between a receiving state in which the stop means is positioned in a first axial position thereby defining how far proximally a received cartridge can be inserted, and an operational state in which the stop means allows an inserted cartridge to be moved axially to a second more proximal position.

1. A drug delivery device adapted to receive a cartridge comprising a cylindrical body portion, a distal outlet portion and an axially displaceable piston, the drug delivery device comprising:
a housing, a front-loaded cartridge holder adapted to receive and hold a cartridge in a loaded position, and a stop member adapted to engage a proximally facing surface of a received cartridge, the stop member being actuatable between:
a receiving state in which the stop member is positioned in a first axial position thereby defining how far proximally a received cartridge can be inserted, andan operational state in which the stop member allows an inserted cartridge to be moved axially to a second more proximal position.
