A MEDICAMENT DELIVERY DEVICE COMPRISING A MANUAL ACTIVATION MEMBER WITH IMPROVED GRIPPING AND ACTIVATION ABILITIES.

摘要

The present invention relates to a medicament delivery device comprising a housing having opposite distal and proximal ends, and adapted to store a medicament container assembly to which a delivery member may be attached; a drive member interactively connected to said medicament container assembly for expelling a dose of medicament; a dose actuation assembly operably connected to said drive member; and an actuation member interactively connected to said housing and as well as to said dose actuation assembly by a gear assembly;wherein the actuation member is arranged to be movable in a direction generally perpendicular to a longitudinal axis of the device from an initial position in which the actuation member is positioned within the housing to a dose-set position in which a portion of the actuation member protrudes a certain distance, proportional to the set dose,from the longitudinal surface of the housing when the dose actuation assembly is manually operated for setting a dose and wherein the actuation member is arranged to be manually operated in a direction generally perpendicular to the longitudinal axis of the device from the dose-set position to the initial position for driving the dose actuation assembly and thereby the drive member.
