Abstract
An apparatus and system for transferring a liquid, such as a liquid anesthetic, from a reservoir to a machine while minimizing the release of the liquid to the surrounding environment. The apparatus can include a frame member defining a frame passage extending from a first end of the frame member to a second end of the frame member and a nozzle connected to the frame member. The nozzle can be moveable between a first position and a second position relative to the frame member, and can define a plug member configured to block the second end of the frame passage when the nozzle is in the first position. The apparatus can further include a biasing member connected to the frame member and the nozzle.
