Abstract: An injection device may include a housing and a baseplate coupled to the housing. The baseplate may include a flange portion and an axial portion that extends from the flange portion in a longitudinal direction of the housing. The baseplate may be an opaque, polymer material that is more thermally conductive than a material of the housing. The injection device may additionally include a syringe at least partially disposed within the housing. The syringe may include a needle. The injection device may include a deployment mechanism configured to move the syringe relative to the housing from a retracted position to a deployed position in which the needle projects beyond the baseplate. At least a portion of the syringe may be visible when the syringe is in the retracted position.
