Functional test
NOTE
Connecting several septic fluid jars in series can cause delayed suction effect and
reduced suction power.
Prior to each use, carry out the following functionality checks:
• All components are properly attached.
• The mains cable is undamaged.
• Components made of plastic or rubber (e.g. control panel film, tube, septic fluid jar cap, septic
fluid jar) are in good condition and show no damage due to ageing.
• Bacterial filter paper is in proper condition.
• The overflow protection device and hydrophobic bacterial and viral filter are mounted and
functional.
• The overflow protection device and hydrophobic bacterial and viral filter have been properly
cleaned and neither residue nor contamination are present.
• Tube connectors and septic fluid jar cap are tightly seated and do not leak.
• No mechanical forces are acting on the tubes.
• Tubes may not be kinked.
•
Maximum vacuum of approximately −90 kPa is reached within about 20 seconds when the
connection tube is held shut.
• The vacuum can be infinitely variably regulated throughout the entire range.
• The septic fluid jar is attached to the aspirator.
• The aspirator has been properly cleaned and neither residue nor contamination are present.
• Damaged parts have been replaced by new parts.
4.2
Suction
WARNING!
Backflow of aspirated secretion!
In the event of oversuction, the aspirated secretion may flow back to the patient if
there is secretion still left in the suction tube.
Before replacing the septic fluid jar in the event of oversuction or switching off the
vacuum, always remove the tube from the patient first.
WARNING!
Risk of injury!
Use an extraction catheter with openings at the side during endobronchial
extraction.
WARNING!
Injury hazard if the catheter attaches itself to tissue!
Always use a fingertip so that the extraction process can be interrupted quickly by
releasing the fingertip.
