7 Safety Functions
The electronic components continuously monitor the proper function of the sys-
tem. System malfunctions are indicated with audible warning signals, error mes-
sages, and/or the blocking of system functions. A table listing a summary of pos-
sible error and warning messages is provided in Error and Warning Messages
[} 48].
If the intrauterine pressure exceeds the intrauterine pressure setting by 10 mmHg
for longer than 5 seconds, the pressure reduction function is activated. The roller
wheel will move forward or backward a few times during the pressure reduction
process. If the pressure cannot be reduced, the message Overpressure/ Open Stop-
cock is displayed, and three audible warning signals are emitted.
The message Maximum Pressure is displayed, and the pump will emit 3 audible
warning signals once the intrauterine pressure exceeds 150 mmHg. The maximum
permissible pressure has now been reached.
If the intrauterine pressure exceeds 200 mmHg for longer than 5 seconds, the
roller wheel stops, and the message Overpressure/Check Stopcock is displayed.
Three short continuous audible warning signals are emitted until the pressure is re-
duced. Once the intrauterine pressure falls below 200 mmHg, the audible warning
signals stop and the pump wheel resumes turning automatically.
If the inflow tube set is not inserted properly into the roller wheel, pressing the
Prime button results in a short audible warning signals and Check Tube Set Install-
ation is displayed. The roller wheel does not start to turn.
If a malfunction is detected in the pressure measurement electronics, Sensor Error
is displayed, and five short audible warning signals are emitted. The roller wheel
stops turning.
If the maximum permissible weight of the scale is exceeded (bag scale or container
scale, a continuous audible warning signals is emitted, and Scale Overloaded Check
Scale is displayed. The warning stops once the excess weight is removed from the
scale.
The following messages are displayed when a container is removed from the scale
or a new fluid bag is added during operation of the system: Container Change,
Press Resume or Bag Change, Please Proceed.
If the last pre-set intrauterine pressure setting is greater than 80 mmHg, this value
is reset to the default value of 80 mmHg.
Each additional deficit increase by 100 ml above the selected deficit threshold trig-
gers 3 audible warning signals that are repeated while the pump continues to op-
erate. The message Deficit Limit Exceeded is displayed.
If the deficit rate exceeds 300 ml/min, 3 audible warning signals are emitted, and
the message High Fluid Loss Check Leakage is displayed. If no obvious source of
high fluid loss can be identified, an assessment of potential cervical or uterine per-
foration should be made.
Five short audible warning signals are emitted, and the message Motor Error is dis-
played. It is possible that errors can occur in the startup sequence prior to the en-
abling of the pump display. In this situation, the pump display will remain blank.
