A liquid transfer device includes a monolithic trifurcated connector body defining a barrel at a first end thereof, a single IV spike at a second end thereof and a vial adapter lumen at a third end thereof. An IV port is connected to the barrel. The single IV spike has a first IV spike lumen fluidly connected at a proximal end thereof with only the vial adapter lumen via the trifurcated connector body and a second IV spike lumen fluidly connected at a proximal end thereof with only the IV port via the trifurcated connector body, thereby separating fluid communication between the vial adapter and the single IV spike from fluid communication between the IV port and the single IV spike.
