Abstract
A medicament delivery device comprising a body, a needle, and an actuation member movable proximally from an initial position to a protruded position, and distally from the protruded position to an actuation position. The device has a transfer member which is movable proximally between an extended and a retracted position. In the extended position the distal end of the transfer member protrudes from the body. One of the actuation member and the transfer member has a drive slot and the other of the actuation member and the transfer member comprises a protrusion located in the drive slot. The drive slot has a circumferentially-extending portion having an abutment surface. The protrusion engages the abutment surface to move the actuation member from the initial position to the protruded position.
