ABSTRACT:
A system is provided for draining an anesthetic agent from a reservoir of an anesthetic vaporizer. The system includes an anesthetic agent container having an inlet into which the agent can drain. The vaporizer has a draining station that defines an outlet and that defines a drain passage between the vaporizer reservoir and the outlet. A valve is operable to open and close the drain passage. A connector is provided with a receiving end for connecting to the draining station at the outlet. The connector has a discharge end for connecting to the container inlet. The connector holds the container below the draining station outlet and defines a transfer passage between the receiving end and the discharge end for draining the agent from the draining station into the container. Structural key configurations, uniquely associated with a specific anesthetic, are preferably provided at the connection of the container and connector and at the connection of the draining station and connector.
