Medicament Delivery Device Comprising a Manual Activation Member with Improved Gripping and Activation Abilities

A medicament delivery device, comprising:

• a housing having opposite distal and proximal ends and configured to store a medicament container assembly;
• 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 to said dose actuation assembly by a gear assembly;
• wherein the actuation member comprises gear racks extending in a direction generally perpendicular to a longitudinal axis of the device and configured for engagement with the gear assembly, whereby said actuation member is movable in a direction generally perpendicular to the longitudinal axis 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 distance proportional to a set dose from a longitudinal surface of the housing when the dose actuation assembly is manually operated for setting a dose;
• and the actuation member is configured to be manually operated in a direction generally perpendicular to the longitudinal axis from the dose-set position to the initial position for driving the dose actuation assembly and thereby the drive member.
