The fill port defines an open interior. The open interior is configured to receive the nozzle of an anesthetic bottle. An agent reservoir is configured to receive and store anesthetic agent. A valve is disposed between the open interior and the agent reservoir. At least one vent extends through the fill port. A method of filling a vaporizer includes inserting the nozzle of a bottle filled with anesthetic agent into a vaporizer filler. At least one vent is occluded from fluid communication. Fluid communication between and open interior and an agent reservoir is opened. Anesthetic agent is poured into an agent reservoir of a vaporizer. Fluid communication is closed between the open interior and the agent reservoir. At least one vent is opened to fluid communication with the open interior. Pressure within the open interior is released through the at least one vent. ## Claims ### Claim 1 A method of filling a vaporizer, the method comprising: inserting a nozzle of a bottle filled with anesthetic agent into a vaporizer filler, the vaporizer filler having a fill port with an open interior; occluding at least one vent in the fill port from fluid communication with the open interior; opening fluid communication between the open interior and an agent reservoir; pouring the anesthetic agent into the agent reservoir; closing fluid communication between the open interior and the agent reservoir; opening the at least one vent in the fill port to fluid communication with the open interior; and releasing pressurized gas from within the open interior through the at least one vent. ### Claim 2 (depends on 1) The method of claim 1, wherein occluding the at least one vent comprises: translating an elastomeric seal within the fill port between a first position that opens the at least one vent to fluid communication with the open interior and a second position that occludes the at least one vent from fluid communication with the open interior. ### Claim 3 (depends on 1) The method of claim 1, wherein releasing pressurized gas from within the open interior exhausts anesthetic agent through the at least one vent. ### Claim 4 (depends on 3) The method of claim 3, further comprising directing the exhausted anesthetic agent through the at least one vent in a pre-determined direction. ### Claim 5 (depends on 4) The method of claim 4, wherein the at least one vent directs anesthetic agent to a gas scavenger. ### Claim 6 (depends on 4) The method of claim 4, wherein the at least one vent directs anesthetic agent to an expansion chamber. ### Claim 7 (depends on 6) The method of claim 6, wherein the at least one vent directs anesthetic agent to a retainer disposed within the expansion chamber. ### Claim 8 (depends on 1) The method of claim 1, wherein opening the at least one vent comprises: translating an elastomeric seal within the fill port from a second position that occludes the at least one vent from fluid communication with the open interior and a first position that opens the at least one vent to fluid communication with the open interior. ### Claim 9 (depends on 1) The method of claim 1, wherein opening fluid communication between the open interior and an agent reservoir comprises: actuating a valve disposed between the open interior and the agent reservoir.
