Safety Notes

Using the Hysteroscopy Indication
en
Differential volume > threshold value If the differential (deficit) volume exceeds the set threshold value, a short warn-
ing beep is emitted 3 times and the screen depicts the following: Deficit exceed-
ed!.
Every additional 100 ml the value exceeds the threshold value is indicated with
the same warning signal.
10.14.4Exceeding Nominal Pressures When Using Standard Tube Set
Overpressures may occur during device operation. The device features corre-
sponding safety mechanisms that support the physician performing the surgery
in deciding on appropriate responses.
Actual pressure > nominal pressure If the actual pressure exceeds the nominal pressure,the following safety mecha-
nisms are automatically triggered by the device:
• Immediately: A pressure relief function is activated that consist of turning the
roller wheel backwards.
• If the actual pressure falls below the nominal pressure, the roller wheel starts
turning forward again and irrigation continues.
Actual pressure > nominal pressure
+10mmHg
If the actual pressure exceeds the nominal pressure by more than 10 mmHg (ex-
ample: nominal pressure = 45 mmHg, actual pressure = 56 mmHg), the following
safety mechanisms are automatically triggered by the device:
• Immediately: A continuous acoustic signal is emitted. The status line depicts
Overpressure! in red letters.
• A pressure relief function is activated that consist of turning the roller wheel
backwards.
• If the actual pressure falls below the nominal pressure, the roller wheel starts
turning forward again and irrigation is continued. The warning message in the
status line is no longer displayed.
Actual pressure > 150 mmHg If the actual pressure exceeds a value of 150 mmHg, the following safety mech-
anisms are automatically triggered by the device:
• Immediately: The color of the actual pressure display bar changes from blue to
red. The center of the bar depicts the actual pressure.
• A pressure relief function is activated that consist of turning the roller wheel
backwards.
• If the actual pressure falls below the nominal pressure, the roller wheel starts
turning forward again and irrigation is continued.. The warning message in the
status line is no longer displayed.
Actual pressure > 200 mmHg If the actual pressure exceeds a value of 200 mmHg, the following safety mech-
anisms are automatically triggered by the device:
• Immediately: A continuous acoustic signal is emitted. The status line depicts
Critical overpressure! in red letters.
• A pressure relief function is activated that consist of turning the roller wheel
backwards.
• The roller wheel stops after 5 additional seconds.
• If the actual pressure falls below the nominal pressure, the roller wheel starts
turning forward again and irrigation continues. The warning message in the
status line is no longer displayed.
