Abstract
An adapter is provided with a base mountable on a bottle containing a liquid anesthetic agent. A spout extending upwardly from the base is received by an inlet port of an anesthetic vaporizer having a movable valve assembly and a stationary portion, such as a radial ledge. The spout includes a stationary contact member configured to contact and open the vaporizer valve assembly when the spout is inserted into the inlet port. The adapter also includes a movable valve assembly that is contacted and opened by the stationary portion of the inlet port when the spout is inserted into the inlet port. The contact member and adapter valve assembly are arranged such that, when the spout is inserted into the inlet port, the contact member opens the vaporizer valve assembly before the stationary portion of the inlet port opens the adapter valve assembly.
