A system and apparatus are provided for connecting an anesthetic container (14) to a vaporizer. Indicia are provided on the container (14) or on a transfer tube (12) connected to the container (14) and the indicia can include mechanical keys, electrical keys and electronic keys. A transfer device is provided for mounting to the vaporizer and engaging the container (14) or transfer tube (12) connected to the container (14). The transfer device includes a sensing system such as a key or code reader system. A clamping mechanism is provided for clamping the container (14), or end pin (16) of a transfer tube (12) connected to the container (14), in a leak-tight engagement within the transfer device. The transfer device can accommodate movement between a fill position and a drain position. The internal fluid flow passages are blocked except when the transfer device is in the fill or drain position.

[ What is claimed is:] [1.] A device for receiving a coupling member of a transfer tube connectible to an anesthetic container wherein said coupling member defines at least one anesthetic discharge passage, said coupling member includes a pin for engaging said transfer device, said device comprising:a body defining (1) a receiving cavity for said coupling member, (2) a fixed cam surface, and (3) at least one fluid transfer passage extending from said receiving cavity through said body;a rotatable member mounted for rotation on said body and defining a rotatable cam surface; anda clamp member disposed in said body adjacent said receiving cavity and having a first cam follower surface adjacent said fixed cam surface and having a second cam follower surface adjacent said rotatable cam surface whereby rotation of said rotatable member drives said clamp member against said coupling member to clamp said coupling member within said body with communication established between said discharge passage and said transfer passage;wherein said pin includes at least one indicium thereon, said device further including a sensor for sensing said indicium.
