Abstract

An injection device comprises a housing containing a cartridge, a needle holder including an injection needle, and a cap. The cap is removably engaged with the housing. The injection device also comprises a translating mechanism configured such that linear distal movement of the cap causes proximal movement of the needle holder such that the injection needle pierces the cartridge.
