Abstract
A medicament delivery device comprises: a needle for injecting a medicament; a body; a needle cover axially movable relative to the body between an extended position and a retracted position; a needle cover biasing member configured to bias the needle cover distally; a medicament delivery mechanism; and a latch movable by the needle cover between an engaged configuration, in which the latch prevents delivery of the medicament, and a disengaged configuration, in which the latch allows delivery of the medicament, wherein the needle cover is configured such that: proximal movement of the needle cover from the extended position towards the retracted position moves the latch from the engaged configuration to the disengaged configuration; and distal movement of the needle cover from the retracted position towards the extended position moves the latch from the disengaged configuration to the engaged configuration.
