Abstract
Drug delivery devices adapted to receive liquid medication vials to fill a reservoir, utilize sliding through valves that are closed except when driven by force of liquid medication pushed by a plunger to an open position to feed the medication via needle to a patient or via a connection to an IV port. The devices have multiple seals and automatically close up when pressure on the plunger is released. The methodology is also included.
