Using the Pump during Surgery


Open bag clamps on the fluid bags ((3) Fig. 5-11).

Fully open hysteroscope inflow stopcock.

If drainage stopcock is available: Fully close drainage stopcock.

Keep the hysteroscope at the height of the patient and above the drape to
ensure the fluid can be collected. Do not insert the hysteroscope into the
uterus at this time.

Press the button Prime ((17) Fig. 5-1).

Pump will run for approximately 20 seconds to purge air from tubes and run
the automatic lumen calibration function.

Pump will display Calibration Running.
The pump is equipped with an automatic lumen calibration function. The system
determines the flow resistance of the hysteroscope. This resistance is used to cal-
culate the pump pressure necessary to maintain the pre-set intrauterine pres-
sure. To overcome this resistance, the pump allows a pressure of up to 80 mmHg
during calibration. This will be shown in the display of the actual intrauterine
pressure. If calibration fails due to high resistance, calibration is repeated with a
permissible pressure of up to 150 mmHg. If calibration is then still not completed,
the pump displays Prime Fail - Open Stopcock Clamps.
The automatic lumen calibration starts once the Prime button is pressed.

Three beeps are heard once the automatic lumen calibration is finished. The
pump display will show Prime Successful Close Stopcock for 5 seconds fol-
lowed by System Operating.

Close hysteroscope inflow stopcock to stop fluid flow. Once all fluid has been
removed from the drape, zero the deficit display.

Check to see if fluid has leaked in the area of the pressure chamber. If you
find leaked irrigation fluid in the area of the pump, change the tube set and
retry the automatic lumen calibration.
NOTE!
The calibration must be performed outside of the patient to ensure a correct lu-
men calibration and deficit calculation.
NOTE!
The pump continues to operate after automatic lumen calibration is complete.
The pump should be stopped by closing hysteroscope inflow stopcock.
CAUTION!
A new lumen calibration must be carried out with each change of the hystero-
scope during surgery (5.15, Changing Instrument during Surgery).

Open stopcock and guide the hysteroscope with fluid flowing into the uter-
us.

Adjust intrauterine pressure setting as necessary to obtain adequate disten-
sion and visualization.

After the medical procedure, if system operation is complete close the hys-
teroscope inflow stopcock.

Wait until the entire fluid volume from the drape and the tube set has been
collected in both containers.

Press the Pause/Resume button.

Note the deficit volume indicated on the deficit display. This is the total fluid
volume that was absorbed by the patient.
