D. CONNECTING THE ASPIRATION TUBING
Steps What to do
IMPORTANT WARNINGS

1 Check the integrity of
the aspiration tubing
(#19138)
Visually check tubing integrity before and after set up.
MORIA strongly advises against the re-use of aspiration tubing as
it may damage connector, resulting in vacuum loss or damage the
vacuum pumps.
2 Connect the sterile,
single use aspiration
tubing (#19138) to the
unit:
• place the chamber
in position (H1)
• then get it down
(H2)
Change tubing for each patient.
Poorly connected tubing, either on the console or on the ring, may
also cause insufcient aspiration. It is very important to check the
integrity of all connections.
Warning:
• do not reverse the chamber position of the aspiration tubing
(H3)
• if liquid appears in the chamber, replace the chamber
immediately (H4)
• visually check tubing integrity before and after set up (H5)
If moisture seeps into the console, activate vacuum to remove it.
If water is sucked up, it is recommended to let the pumps run to let
residual water out.

1 Clamp the aspiration
tubing at its end (close
to the ring connector)
Before connecting the suction ring on the aspiration tubing, check
that internal air lumen of the ring are not obstructed by surgical
residues.
This obstruction, resulting from insufcient or inappropriate
cleaning, would create pseudo-aspiration and risk the loss of
vacuum.
2 Press the test button
(A8)
The unit will check each
pump: P1, then P2.
Vacuum test ends with a
short audible “beep”.
This test procedure will check the efciency of the pumps and the
pressure (if gas turbine is selected).
The test should be made :
• prior to surgery,
• whenever tubing is changed,
• whenever a red indicator light is illuminated
The unit can only be operated if the test is passed.
The display (A7) indicates:
• “PE”
• then atmospheric pressure (mmHg)
• then “P1”
• then the pressure obtained by pump P1 (mmHg)
• then “P2”
• then the pressure obtained by pump P2 (mmHg)
• then atmospheric pressure (mmHg)
When atmospheric pressure “PE” is indicated on the display, one
can hear a single “beep”.
Stopping suction is indicated by a “beep” sound”.

3 The test is passed if
LED (A3) is ON
The vacuum level provided by the console depends on the local
atmospheric pressure, and thus on the elevation. The system
displays the actual vacuum value (in mmHg).
The higher the elevation, the less efcient the suction. The
atmospheric pressure decreases with elevation (approx: 8
mmHg/100 m).
The suction capacity is proportional to the difference in pressure
between the lowest level of vacuum pump and the local
atmospheric pressure.
The higher the vacuum power, the smaller the value displayed.
When the ring is xated on the eye the vacuum value must be less
than 250mmHg. If the value displayed is above, the unit must be
immediately turned off and sent back to Moria for a servicing.
