Systems and devices for interfacing between a medicinal vial, a hypodermic needle, and an injection device such as a syringe, comprising a valve, functionally associated with said vial adaptor, said injection device port, and said needle, said valve having a first orientation wherein said injection device port is in fluid flow communication with said vial adaptor and a second orientation wherein said injection device port is in fluid flow communication with said hypodermic needle, wherein rotation of said injection device port between a first position and a second position thereof, drives transition of said valve from said first orientation to said second orientation.
