Medicament delivery device

Abstract

A medicament delivery device includes a needle disposed at a distal end of the medicament delivery device. The medicament delivery device includes a body for a syringe and a needle cover axially movable relative to the body between an extended position in which the needle cover covers the needle and a retracted position in which the needle protrudes from the distal end of the needle cover. The medicament delivery device includes a plunger axially movable relative to the body to dispense medicament from the medicament delivery device. The medicament delivery device includes a needle cover biasing mechanism configured to bias the needle cover distally from the retracted position to the extended position. The medicament delivery device includes a locking mechanism configured to be moved by the plunger from an initial configuration to an engaged configuration to prevent a distal movement of the needle cover biasing mechanism.
