Keyed anesthetic vaporizer filling system

摘要

A system for facilitating the delivery of a liquid anesthetic agent from an anesthetic bottle (8) to an anesthetic vaporizer (10). The system includes a bottle adapter (10), an anesthetic bottle (8) and a filler arrangement positioned on the anesthetic vaporizer (9). The bottle adapter and filler arrangement each include a keyed configuration such that only the correct type of anesthetic agent can be emptied into the anesthetic vaporizer. The bottle adapter (10) includes an adapter valve assembly that engages a filler valve assembly contained within the filler. The dimensions and arrangement of the adapter valve assembly and the filler valve assembly ensure anesthetic agent is delivered to the anesthetic vaporizer only when the anesthetic agent can safely flow from the anesthetic bottle to the anesthetic vaporizer.
