Abstract
The present disclosure relates to a medicament delivery device comprising a housing, a needle, a needle cover, a needle cover biasing member, a drive mechanism, and a needle cover extension mechanism. The needle cover is axially movable between an extended position and a retracted position. The needle cover biasing member is configured to bias the needle cover axially in the distal direction towards the extended position. The needle cover extension mechanism comprises a second biasing member and a release element. The second biasing member is configured to bias the needle cover into its extended position post-use of the device. The release element has a first state configured to prevent the second biasing member from biasing the needle cover into the extended position and a second state configured to allow the second biasing member to bias the needle cover into the extended position.
