Do not ignore the safety mechanism.
3.4.1 Filling and Draining the Vaporizer
Install the vaporizers with a Selectatec® interlock system that are compliant with ISO 80601-2-13 on
the unit. Refer to the vaporizer manufacturer’s Instructions For Use for filling or draining the vaporizer
and other information.
WARNING: Ensure that the correct anesthetic agent is used. The vaporizer is designed
with the specific anesthetic agent named on it and further indicated by
color coded labeling. The actual output concentration of the anesthetic
agent will vary if the vaporizer is filled with the wrong agent.
WARNING: The anesthetic liquid discharged from the vaporizer must not be used
again. Please regard it as a dangerous chemical and dispose of it
properly in accordance with local regulations.
3.5 Negative Pressure Suction Device
The negative pressure suction device comprises the negative pressure regulator, the liquid collection
bottle, the suction tube and the filter. It is primarily used to collect the hydrops, hematocele, pus and
other contaminants from the patient’s pharynx. The unit supports overfill protection to prevent
backflow of effluent after the bottle is full to ensure pipeline and tube safety.
1. Place the liquid collection bottle to the bracket. Connect the suction tube, the liquid collection
bottle and the filter following the screen printed instructions.
