Automatic liquid
drug preparation apparatus for preparing a liquid
drug assemblage with a predetermined dosage of liquid
drug. The liquid drug assemblage is prepared from a preparatory assemblage including a
fluid control device having a body member with a
syringe port, a
vial adapter, and an administration port, a
vial pre-filled with
powder or liquid medicament, and a
syringe pre-filled with
diluent for mixing with the medicament. The automatic liquid drug preparation apparatus includes a housing, a cradle for receiving the preparatory assemblage, and a controller for controlling a motorized
syringe drive unit for selectively transferring liquid contents between the syringe and the
vial, a motorized cradle drive unit for selectively rotating the cradle relative to the housing, and a motorized
vial adapter release unit for selectively detaching the
vial adapter with its attached spent vial from the body member to form the liquid drug assemblage.
