System Operation
EN
Connect the blue Luer lock connector
(9)
with the hysteroscope inflow stop-
cock. Open stopcock.
Insert tube set
3. To be carried out by non-sterile nurse:
Ensure system is turned on.
Close the clamps
(3)
on the inflow tubing below the bag spikes
(1)
.
Insert the inflow tube set into the inflow tube holder.
Insertion of the roller wheel tube is depicted in Figure 5-11, Positioning the
roller wheel tube.
Carefully insert the pressure chamber
(7)
into the lower notch of the inflow
tube holder
(12)
until you feel resistance. Align pressure chamber and inflow
tube holder using arrows (see Figure 5-11, Positioning the roller wheel tube).
When inserting the roller wheel tube, ensure not to damage the membrane
of the pressure chamber. Insert the pressure chamber
(7)
only if chamber is
not pressurized.
Place the roller wheel tube
(6)
around the roller wheel
(11)
.
Connect the fluid bags
When connecting or removing the tube to or from the irrigation fluid bags,
grasp the bag spike at the provided handle. Observe aseptic technique when
inserting the spike(s) into the fluid bag(s). The surgeon must select a disten-
sion fluid suitable for the type of procedure.

Presetting the Intrauterine Pressure
Intrauterine pressure setting
The intrauterine pressure setting can be adjusted while the system is in opera-
tion. Use the
º
and
»
buttons (Fig. 5-1, Front of Pump). The pressure setting can
be adjusted to between 40 to 150 mmHg in steps of 5 mmHg. The intrauterine
pressure is shown on the intrauterine pressure display
(2)
.
Safety threshold
When scrolling with the
º
button (Fig. 5-1, Front of Pump) if the safety threshold
of 100 mmHg is reached, an audible tone is emitted. Release the
º
button for one
second and scroll again to set higher values up to 150 mmHg.
CAUTION!
If the intrauterine pressure does not react to an increase in the pressure setting
during the procedure, a perforation of the uterine cavity might be the cause. This
results in an increased risk of intravasation. Examine the uterine cavity for inju-
ries.
5.11
Setting the Deficit Limit
Deficit limit setting
The deficit limit can be adjusted while the system is in operation. Use the
º
and
»
buttons (Fig. 5-1, Front of Pump). The deficit limit can be adjusted to between
600 to 2500 ml in increments of 100 ml. The deficit limit is shown on the deficit
limit display
(3)
. The deficit meter is designed to help the user track the deficit
volume. The color of the deficit meter changes as the deficit limit is approached.
The user set deficit limit is marked with a red LED on the top of the deficit meter.
