rings are autoclavable. However, the filter capsules are ‘Single Patient Use’ and must not be
autoclaved. The external filter must be changed with every patient and renewed in accordance with
the recommendations detailed in the ‘Daily Procedures’.
Warning! The filter capsules are made to withstand limited use and cannot be reused.
Reuse of such devices can be dangerous for both patient and operator.
3.6 Internal Filter
The SA unit must have fitted internally a hydrophobic filter capsule to prevent ingress of foreign
material into the pump. The hydrophobic filter prevents costly pump damage as well as additional
protection against contamination from liquids being sucked through due to jar overfill. Liquid sucked
through to the pump motor will cause damage and invalidate the warranty. The filter is disposable and
must not be autoclaved, but renewed in accordance with the recommended maintenance program.
Warning! A hydrophobic filter must be fitted internally to prevent liquid passing through to
the pump. Hydrophobic filters only work once and should be replaced
immediately it becomes wetted.
3.7 Fluid Collection Containers
The silicon service tube (∅6mm I/D with 3mm minimum wall thickness) must be connected between
the filter and the vacuum port on the collection container. The tube has an elbow connector on each
end for fitting to the filter and for fitting to the ‘VACUUM’ port of the SA 2 collection container. The
silicon tubing used in conjunction with this equipment is a replaceable item. It should be changed
regularly according to the level of usage and where it has become in any way contaminated or
damaged.
Warning! All collection containers must be securely mounted when in use.
An anti-foam agent may be put into the fluid collection container, without disinfectant solution, before
use to reduce the possibility of frothing. It should not however, be placed into the container for
extended storage periods.
3.7.1 SAM 2 Collection System
The SA 2 collection container is fitted as standard to all SA units. They are fully autoclavable
Polyester Carbonate (P.E.C.) collection containers, with integral handle and for IU applications, with a
wide bore. The container is connected to the SA unit via a moulded vacuum connector of the same
type as that fitted to the filter capsules.
• Place the collection container in the
bracket. Connect the tubing from the filter
to the angle connector in the centre of the lid.
• Connect the patient tube to the patient connection.
• Turn on the SA suction unit.
• Check the desired vacuum is established.
• After the suction procedure – disconnect the patient tube.
The SA 2 is fitted with an overflow valve designed to shut off the vacuum to the SA 2 collection
container when the fluid level reaches 1750ml. When the valve operates, the SA 12 and SA 15 units
must be switched off and the full container replaced by an empty one. The SA 14 and SA 16 have
two SA 2 collection containers and where appropriate the full container may be replaced by the
second container through operation of the changeover valve located on the top of the unit.
It should be noted that even after the valve has shut off, fluid might continue to be drawn into the
container to an extent dependent upon the level of vacuum in the container at the time when the valve
closes.
