The reusable canister must be cleaned if needed
according to manufacturer’s instructions for use.
Clean the Serres Vacuum Connector by wiping
with a damp cloth or a sponge. Do not autoclave
or attempt to disassemble.
5.3 Use
Note: Read all the cautions and warnings listed in
section 1 thoroughly before you use the LSU.
5.3.1 Check list
• Check that no parts are missing and that all
parts are clean.
• If you decide to operate the LSU from
external power, connect to either external
AC or DC power as described in section 3.4.
If you decide to operate the LSU from
internal battery, check that the battery is
installed and charged.
• Check that the Serres Vacuum Connector is
properly connected to the LSU and to the
canister
Check that the lid of the canister is properly sealed:
1 Block patient inlet and turn on the LSU.
2 Vacuum will build up when all parts are
assembled correctly.
5.3.2 Using the LSU
Note: The LSU should be operated and
transported in the upright position to prevent
overflow of suctioned material.
1 Unwrap the Serres Suction Tube.
2 Connect the Serres Suction Tube to the
Patient inlet on the canister lid.
3 Attach appropriate suction catheter if
necessary. Not supplied by Laerdal Medical.
4 Set the Operating Knob to the required
vacuum level and the LSU will automatically
be switched on and start to operate.
The green power ON Indicator is lit
continuously while the LSU is switched on.
5 When suctioning is complete, set the
Operating Knob to “0”.
5.3.3 Empty the canister
Note: It is recommended to replace the Suction
Bag when it is ¾ full.
When liquid reaches approximately 1000 ml,
the LSU will not suction any more liquid. If
overflow of liquid from the bag into the pump is
suspected, the LSU must be returned to service
(see section 8).
Overflow of suctioned material can damage the
LSU.
Disconnect Serres Suction tube. Safely dispose
of the Serres suction tube according to local
protocols.
