Abstract:
1. A system for transferring fluidic media, the system comprising: an outer reservoir having an interior volume for containing fluidic media; and an inner reservoir having an interior volume, the inner reservoir having a septum pierceable by a needle, the needle for providing a path from a vial containing fluidic media to the interior volume of the inner reservoir in a case where a first end of the needle is in the vial and a second end of the needle opposite the first end of the needle is in the interior volume of the inner reservoir; the outer reservoir having a septum pierceable by the needle, the needle for providing a fluid path from the vial containing fluidic media to the interior volume of the outer reservoir in a case where the first end of the needle is in the vial and the second end of the needle is in the interior volume of the outer reservoir; at least a portion of the inner reservoir configured to be moveable in the outer reservoir between at least a first inner reservoir position and a second inner reservoir position wherein pressure in the interior volume of the inner reservoir is substantially equal to pressure in the vial when the inner reservoir is in the first inner reservoir position; and wherein pressure in the vial is greater than pressure in the interior volume of the outer reservoir when the inner reservoir is in the second inner reservoir position.
