ABSTRACT:
A reusable connector is provided for mounting on an anesthetic vaporizer to connect the vaporizer with an anaesthetic container and hold the container in an inverted orientation. Cooperating engaging structures are employed to pull the container and connector together. In a preferred form, the container has a closure defining at least one port occluded by a recessed, pierceable membrane. A screw thread is provided on the container. The connector has a base provided with a first coupling for connecting the base to the vaporizer. The base has a second coupling that includes plug adapted to be connected to the container closure, The base also defines a passage extending from the plug through the first coupling for communicating with the vaporizer, The plug includes at least one projecting conduit that communicates with the passage and that defines a piercing tip for entering into the port to pierce the membrane, A collar is mounted for rotation on the base, The collar engages the base and defines a screw thread for engaging the thread on the container to pull the container onto the plug as the membrane is pierced.
