The compact anesthesia system uses a keyed filling system to ensure
maximum safety and maximum accuracy. The keyed filling system
consists of three elements:
• the bottle collar
• the adapter
• the filling/draining unit fitted to the vaporizer
Key fill and drain systems are designed to prevent the wrong agent from
being used in the vaporizer. For example, an Isoflurane vaporizer cannot
be filled using a Halothane bottle adapter. Similarly, the Halothane bottle
adapter will not fit on the Isoflurane bottle or into the Isoflurane
vaporizer.
To fill the vaporizer:
Attach the bottle adapter to the
1.
appropriate bottle.
Ensure the vaporizer control is set in the
2.
'Off' position.
Turn the top retaining screw
3.
counterclockwise and pull out the filler plug.
Turn the cap slowly if the vaporizer is
4.
pressurized.
Insert the keyed block of the adapter
5.
fully into the filling tunnel, with the two
holes aimed DOWN.
• To prevent spillage, take care to bend
the tube slightly so the bottle is situated
below the inlet level.
Turn the retaining screw above the
6.
filling tunnel clockwise and tighten to seal
the fill adapter in the filling tunnel.
Raise the bottle above the level of the
7.
filling tunnel, without kinking the tube. A
steady stream of air bubbles should emerge
from the inner tube within two seconds.
