Abstract
A medicament delivery device comprises a housing, a needle, a needle cover, a needle cover biasing member, a skin sensor, a skin sensor biasing member, and a retaining 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 towards the extended position. The skin sensor extends from the distal end of the needle cover and is configured to contact an injection site. The skin sensor biasing member is configured to bias the skin sensor from a proximal position to a distal position away from the needle cover. The retaining mechanism is configured to temporarily retain the needle cover in the retracted position and transfer at least a part of the force of the needle cover biasing member to the housing to prevent the needle cover biasing member from moving the needle cover distally.
