A double lumen tube adaptor and valve assembly for lung anesthesia circuits, said assembly comprising: a housing, a central passageway in said housing, a pair of lateral passageways in said housing, a plurality of inlet ports in said housing including a pair of lateral ports each fluidically communicating with a separate one of said lateral passageways and a common inlet port fluidically communicating with said central passageway, each of said inlet ports including means adapted for connection to a medical anesthesia machine, a pair of outlet ports in said housing, each fluidically communicating with a separate one of said lateral passageways and separately aligned with a separate one of said lateral inlet ports, each of said outlet ports including means adapted for connection to a patient circuit patient, and a pair of valve members rotatably mounted in said housing in alignment with said central and lateral passageways, said valve members each including passage means selectively positionable to be in alignment with said central and lateral passageways for selectively communicating certain of said inlet ports with said outlet ports, said passage means when aligned with said lateral passageways defining a straight-through passage from said lateral inlet ports to said outlet ports.
