Abstract
A system for the delivery of a liquid anesthetic agent to a sump of an anesthetic vaporizer includes a filler assembly rotatable about a pivot point. The filler assembly further includes a sump valve that controls fluid communication between the filler assembly and the sump. An adapter is coupled with the filler spout and includes a sealing surface that forms a seal against fluid communication between the anesthetic bottle and the adapter. The filler assembly, the filler spout, and the adapter are rotated about the pivot point along the rail. The rotation of the filler assembly, the filler spout, and the adapter about the pivot point opens the sump valve and the seal between the adapter and the anesthetic bottle.
