Abstract

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.
