General Safety Functions

The device is equipped with an automatic venting system.
When the insufflator detects that the nominal pressure was exceeded by more
than 3 mmHg for longer than 3 seconds, it automatically activates the venting
system. The status line then depicts Venting active!.
WARNING!
Please note that the automatic venting system is not active during initial insuf-
flation.
WARNING!
The venting rate of the automatic venting system is limited. Always monitor the
actual pressure when using additional insufflation sources.
If the overpressure of more than 3 mmHg exists longer than 5 seconds, the status
line depicts a corresponding message and a warning signal is emitted.
CAUTION!
In case of overpressure above 30 mmHg for longer than 5 seconds insufflation is
deactivated.
When tube, Veress needle, or AirSeal® cannula are blocked, the message Occlu-
sion is depicted and a warning signal is emitted. The actual pressure display de-
picts 0.
The warning signal can be deactivated in the user menu (see chapter 8 "User
Menu"). Remove the occlusion if this is not done intentionally, e.g. with a closed
valve. Check tubes or cannula for proper fit (not in tissue) and check for possible
blockages.
7.2

Contamination Alarm for Standard Insufflation Mode

Contamination occurs when fluid has penetrated the device via the conventional
barbed fitting tube connection. A contamination message and an audible signal
occurs. It is possible to conclude the currently ongoing surgery with this device.
Insufflation is no longer possible after turning the device off and back on using
the ON/OFF switch. This is to prevent cross-contamination.
The display depicts Contamination if you are switching on an already contami-
nated device. The device can no longer be used. The contaminated device has to
be clearly marked as contaminated and sealed in two separate protective layers
of safety foil. Make sure the device can no longer be operated until a qualified
service technician conducts the appropriate tests and repairs.

Safety Functions in AirSeal Mode

The pressure is reduced slowly before the system comes to a complete stop when
stopping the AirSeal® insufflation.
The stopping procedure consists of an automatic calibration routine so that the
unit keeps running a few seconds after stop key is pressed. During this process no
pressure or insufflation is built up.
