These Directions for Use covers two
configurations of the Laerdal Suction Unit (LSU):
Reusable, Serres Suction Bag System. Unless
otherwise specified the information in this
Directions for Use applies to both configurations.
Read these Directions for Use carefully, and
become thoroughly familiar with the operation
and maintenance of the LSU before using it.
1 Cautions and Warnings
The LSU should only be used by persons trained
in the use of medical suction equipment.
The LSU is not suitable for use in the presence of
flammable liquids or gases; there can be a danger
of explosion or fire.
Do not use the LSU under environmental
conditions that are outside the ranges specified
under section 11.6.This can endanger safety and
adversely affect operation of the device.
Do not block the Exhaust Outlet during use.
This will lead to reduced flow and can also cause
damage to the LSU.
Always use the Reusable version with the filter
and the Float Ball in place.
Overflow of suctioned material can damage the
device. If overflow of liquid from the Canister
into the pump is suspected, the LSU must be
returned for service (see section 8).
Disconnect the LSU from external power prior
to cleaning. Use a minimum of liquid to prevent
any electrical shock hazard.
Do not immerse the LSU or allow it to stand
in water or other liquids.This might damage the
device, and cause electrical hazard.
Do not pump any cleaning solution or other
liquids through the vacuum pump, i.e. through the
Vacuum Connector.This can damage the LSU.
Use only accessories supplied by Laerdal Medical
or one of our authorised distributors to ensure
that the LSU operates satisfactorily.
Battery
• Only use batteries approved by Laerdal
Medical. Other batteries will have problems
related to the battery status indicator of the
LSU, the battery operation time, and safety.
• To maintain satisfactory operation of the
battery, it is recommended to place the LSU
on continuous charge when not in use.
• The LSU must be placed on charge for
a minimum of 24 hours to reach full
battery capacity.The fast charging gives
approximately 80% battery capacity after
3 hours (for a new battery). Please note
that repetitive 3 hour charging is not
recommended.
• If it is not possible to place the LSU on
continuous charge when not in use, make
sure the battery is charged for a minimum of
24 hours at least once a month.
• Do not store the battery when it is
discharged; always fully charge the battery
before storage.
• We recommend charging a spare battery
every 6 months when stored in room
temperature at 25°C (77°F ).
2 Intended Use
The LSU is a portable, electrically powered,
medical suction equipment intended for field and
transport use. It is intended for intermittent
operation to remove secretions, blood or vomit
from a patient´s airway to allow ventilation.
Higher vacuum levels are generally selected for
oropharyngeal suctioning, and lower vacuum
levels are usually selected for tracheal suctioning
and the suctioning of children and infants.
