Suction unit
The intended use for the Suction unit is to
extract body fluids from the stomach and
airways.
Suction pressure is regulated by means of the
On/Off switch and the suction unit regulatory
valve. Turning the regulatory valve
counter-clockwise decreases the pressure,
i.e. increases the suction flow. The vacuum
gauge shows the current suction pressure.
The Suction unit is connected to the FLOW-i
Air outlet and is therefore dependant on the
central gas supply pressure for its operation.
The central gas supply pressure should be
above 300 kPa (3.0 bar, 44 PSI) when the
Auxiliary O
2
and suction module is connected
to the system.
MAQUET recommends using single use septic
fluid jars and suction tubings. These shall
comply with ISO 10079-3:2009.
The septic fluid jar used with the unit must
have a usable volume of at least 500 ml and
an integral overflow protection device. The
inner diameter of the inlet to the fluid jar shall
be at least 6 mm.
The length of tubings connecting the septic
fluid jar with the unit shall not exceed 1 m. The
tube material should be rigid enough to
prevent occlusion. The inner diameter of the
tubing connecting the fluid jar with the suction
unit shall be at least 6 mm.
MAQUET recommends using the following
suction unit equipment items (where available):
• SERRES Suction Bag 1000
ml
Art. nr 57157
• SERRES Suction Canister
1000 ml
Art. nr 57308
• SERRES Suction Tubing Art. nr
5823212
A hydrophobic bacterial/viral filter is located
on the back of the suction unit. It protects the
system against contagious particles and acts
as a second overflow protection device in
addition to the device located in the septic
fluid jar. The suction unit cannot be operated
without a correctly placed bacterial/viral filter.
The hydrophobic bacterial and viral filter needs
to be replaced at regular intervals, see Chapter
13, page 245, for more details.
