1. A device for injecting a medicament, comprising:
a housing having a distal end opening and a proximal end opening;
a needle guard;
a biasing member that biases the needle guard in a proximal direction; and
an activation member slidably positioned within the housing such that a first portion of an outer surface of the activation member extends longitudinally from an inside surface of the distal end opening when the activation member is in an initial position, where during injection of the medicament the activation member is moved axially relative to the housing in a proximal direction to a final position such that a second portion of the outer surface extends longitudinally from the distal end opening, where the second portion is smaller than the first portion,
wherein the activation member has a blocking member configured to prevent movement of the needle guard when the activation member is in the final position and the needle guard is in an extended position relative to the housing.
