A vaporizer filling system includes a filler assembly, a sump, and a valve. The valve controls fluid communication into the sump. A retaining device retains the valve in an open position. A delay is connected to the retaining device. The delay controls the operation of the retaining device in order to retain the valve in the open position until the delay detects a release condition. The delay then controls the retaining device to release the valve. A method of filling a vaporizer includes engaging a bottle of liquid anesthetic agent with a filler assembly. The bottle and the filler assembly are moved from a first position to a second position. The bottle and filling assembly are locked in the second position with a retaining device. Then the retaining device is released and the bottle and filler assembly are returned to the first position.

1. A vaporizer filling system comprising: an anesthetic agent source filled with liquid anesthetic agent;a sump configured to receive liquid anesthetic agent;a filler assembly connected to the sump, the filler assembly configured to couple with the anesthetic agent source;a valve disposed between the anesthetic agent source and the sump, the valve controlling fluid communication between the anesthetic agent source and the sump;a retaining device that retains the valve in an open position;a delay connected to the retaining device, the delay controls the operation of the retaining device to retain the valve in the open position until the delay detects a release condition, wherein the delay controls the retaining device to release the valve. 2. The system of claim 1 wherein the anesthetic agent source is a bottle and the bottle is coupled to the filler assembly when the filler assembly is in a first position and the bottle is in a generally upward-opening orientation, the filler assembly further being rotatable between the first position and a second position about a pivot point and rotation of the filler assembly from the first position to the second position moves the valve between a closed position and an open position and moves the bottle into a generally downward-opening orientation. 3. The system of claim 2 wherein the valve is a bottle valve coupled to the bottle and disposed between the bottle and the filler assembly. 4. The system of claim 1 wherein the valve is a sump valve disposed between the filler assembly and the sump; and wherein the anesthetic agent source is a bottle and movement of the filler assembly from a first position to a second position opens the sump valve and pours the liquid anesthetic agent from the bottle into the sump. 5. The system of claim 4, further comprising: a bottle valve between the bottle and the filler assembly, wherein the movement of the filler assembly from the first position to the second position opens the bottle valve. 6. The system of claim 1 wherein the delay is a mechanical timer. 7. The system of claim 1 further comprising: a sensor in association with the sump, the sensor measuring a condition of the sump; andwherein the delay is an electronic controller, the electronic controller being coupled to the sensor, the electronic controller receiving the measured condition of the sump and the electronic controller operates the retaining device based upon the measured condition of the sump. 8. The vaporizer filling system of claim 7, wherein the measured condition of the sump is a volume of anesthetic agent in the sump, and the electronic controller operates the retaining device upon detecting a predetermined volume as a release condition. 9. The vaporizer filling system of claim 8, wherein the electronic controller includes a plurality of release conditions, and the electronic controller operates the retaining device upon detecting at least one of the plurality of release conditions. 10. The vaporizer filling system of claim 9, wherein the plurality of release conditions includes a measured length of time that the retaining device retains the filling assembly. 11. A method of filling a vaporizer comprising a filler assembly and a sump with a bottle of liquid anesthetic agent, a valve being disposed between the bottle of liquid anesthetic agent and the sump, the method comprising: engaging the filler assembly with the bottle when the filler assembly is in a first position;moving the bottle and the filler assembly from the first position to a second position to operate the valve to open fluid communication between the bottle and the sump;locking the bottle and the filler assembly in the second position with a retaining device;operating a controller to maintain the bottle and the filler assembly locked in the second position with the retaining device;releasing retaining device locking the bottle and the filler assembly in the second position;returning the bottle and the filler assembly to the first position. 12. The method of claim 11, wherein the bottle is engaged with the filler assembly such that the bottle moves in unison with the filler assembly; and further comprising the step of: disengaging the bottle from the filler assembly once the filler assembly has returned to the first position. 13. The method of claim 11, wherein operating the controller further comprises the controller monitoring at least one release condition, the controller releasing the bottle and filler assembly from the retaining device upon sensing a release condition. 14. The method of claim 11, wherein the vaporizer comprises at least one sensor associated with the sump, and further comprising: measuring, with the sensor, a condition of the sump; andproviding the measured condition of the sump to the controller;wherein the at least one release condition includes a predetermined condition of the sump, and the controller maintains the bottle and filler assembly locked in the second position with the retaining device until the sensor measures the predetermined condition of the sump. 15. The method of claim 14, wherein the sensor measures the volume of anesthetic agent in the sump and the predetermined condition of the sump includes a volume of anesthetic agent in the sump. 16. The method of claim 15, wherein the at least one release condition further includes a predetermined length of time that the bottle and the filler assembly are locked in the second position and the controller further controls the retaining device to release the bottle and the filler assembly after the predetermined length of time has elapsed. 17. An anesthetic agent vaporizer, comprising: a sump configured to retain liquid anesthetic agent;a filler assembly in fluid communication with the sump, the filler assembly being configured for engagement with an anesthetic agent source, the filler assembly being further movable between a first position and a second position;a valve disposed in the filler assembly, the valve regulates the fluid communication through the filler assembly into the sump wherein the valve is closed when the filler assembly is in the first position and the valve is open when the filler assembly is in the second position;a retaining device that selectively engages the filler assembly to retain the filler assembly in the second position; anda delay connected to the retaining device to control the operation of the retaining device to retain the filler assembly in the second position until the delay controls the retaining device to release the filler assembly to return to the first position. 18. The anesthetic agent vaporizer of claim 17 wherein the anesthetic agent source is a bottle of liquid anesthetic agent. 19. The anesthetic agent vaporizer of claim 18 wherein the delay is an electronic controller that monitors at least one release condition while the retaining device is operated to retain the filler assembly in the second position and the electronic controller operates the retaining device to release the filler assembly when the electronic controller determines that the at least one release condition has been met. 20. The anesthetic agent vaporizer of claim 19, further comprising a volume sensor associated with the sump, the volume sensor measuring a volume of the liquid anesthetic agent in the sump, wherein the at least one release condition comprises a predetermined volume of the liquid anesthetic agent in the sump, and the electronic controller operates the retaining device to release the filler assembly when the measured volume matches the predetermined volume of the at least one release condition.
