A transfer guard may provide a fluid path from a vial to a reservoir containing a plunger head connected to a plunger arm operatively engagable with a handle that at least partially covers a casing configured to allow the handle to operatively engage the plunger arm to move the plunger head to transfer fluidic media from the vial to the reservoir. A support structure may have a chamber, a first adapter for mating with a vial containing fluidic media, and a second adapter for mating with a reservoir containing a plunger head moveable within the reservoir. A first needle may provide a fluid path from the vial to the reservoir and a second needle may connect the vial and the chamber containing an air flow control mechanism for allowing air to flow in one direction.
