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.
Claims32
An apparatus comprising:
- a frame member having a base and a spout, the base adapted to be secured to an opening of a reservoir and the spout having at least one external thread, wherein a through-hole extends through the base and the spout;
- a nozzle having an inner surface with at least one internal thread that is adapted to engage with the at least one external thread on the spout, and an outer surface which is adapted to couple with a machine, wherein the nozzle is moveable between a first position and a second position relative to the frame member;
- a plug member fixedly attached to the inner surface of the nozzle, wherein the plug member is adapted to block the through-hole when the nozzle is in the first position;
- and
- a biasing member coupled to the frame member and the nozzle to thereby bias the nozzle relative to the frame member.
