Safety Functions

The electronic components continuously monitor the proper function of the sys-
tem. System malfunctions are indicated with audible warning beeps, error mes-
sages, and/or the blocking of system functions. A table listing a summary of
possible error and warning messages is provided in Chapter 10, Error and Warn-
ing Messages.
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 Stopcock is displayed and three warning beeps are emitted.
The message Maximum Pressure is displayed and the pump will emit 3 warning
beeps once the intrauterine pressure exceeds 150 mmHg. The maximum permis-
sible 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 beeps are emitted until the pressure is
reduced. Once the intrauterine pressure falls below 200 mmHg, the audible
warning beeps 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 beep and Check Tube Set Installation is
displayed. The roller wheel does not start to turn.
If a malfunction is detected in the pressure measurement electronics, Sensor Er-
ror is displayed and five short warning beeps are emitted. The roller wheel stops
turning.
If the maximum permissible weight of the scale is exceeded (bag scale or con-
tainer scale, a continuous audible warning beep 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 val-
ue is reset to the default value of 80 mmHg.
Each additional deficit increase by 100 ml above the selected deficit threshold
triggers 3 warning beeps that are repeated while the pump continues to operate.
The message Deficit Limit Exceeded is displayed.
If the deficit rate exceeds 300 ml/min, three audible warning beeps 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
perforation should be made.
Five short audible warning beeps are emitted and the message Motor Error is dis-
played. It is possible that errors can occur in the start up sequence prior to the en-
abling of the Pump Display. In this situation, the Pump Display will remain blank.
