Medicament injection device

Abstract:

A medicament injection device includes a main body having a cartridge receiving part configured to hold a medicament cartridge; a needle holder holding a needle; a needle sleeve at least partially surrounding the needle holder and needle and axially movable relative to the main body; a removable transverse blocking member separating the cartridge receiving part and the needle holder; and a compressed spring arranged between the needle holder and a distal end of the needle sleeve so that, upon removal of the blocking member, the spring is released, thereby causing the needle carrier to move axially towards cartridge receiving part.
