WARNING
In the event of continued problems after taking the action outlined above, send the unit to an
authorised service centre for service or repair.
Collection jar
The device is sold with three different types of jar with a capacity of 1000ml:
- reusable, autoclavable OB-J FA jar –OB500 FA
- reusable, autoclavable OB-J jar –OB500 FM
- reusable SERRES® jar with disposable 1000ml bag –OB500 LINER
OB-J FA reusable, autoclavable jar
OB-J FA jar (Fig. 5) is made of transparent plastic material (polyprophilen). The jar includes
pot (1), cover (2), the shut-off valve (3) and the 90° plastic pipe (4). The lid of the jar
provides the direct inclusion of the protection filter.
The jar can be sterilized in an autoclave (max. pressure 2 bar (g) and maximum
temperature 121°C) for a maximum of 15 minutes. It is strongly recommended that the
collection jar is replaced after 30 autoclave cycles. The jar must always be used in the
upright position, to avoid the intervention of shut-off valve. Should this occur, switch the
device off and disconnect the patient tube (‘VACUUM’ marked on the lid).
Protection filter
To prevent fluid overflow, a special protection filter is used between the jar and the unit. The filter is
produced with PTFE hydrophobic material which prevents fluids entering the pneumatic circuit. Working
together with the shut-off valve on the jar, the filter isolates the pneumatic suction pump from gas and
fluid substances. Replace the filter when you look at contamination, discoloration or increased
resistance of aspiration.
Warnings and precautions on the use of protection filter
If the suction unit is used either in an emergency or on a patient where the risk of contamination is not
known, the filter must be changed after each use.
If instead the patient's pathology is known and / or where there is no danger of cross contamination, we
recommend replacing the filter after each shift. In case of complete inactivity of the unit is recommended
Fig. 5

Rev. 04-2010 USMAN2012-IT
12 - 28
Rev. 10-2018 USMAN500 - UK
to replace the filter once a month. The material it is made should be damaged even under specific
environmental conditions (humidity, heat, cold)
Do not use the suction unit without the protection filter or jar!
Reusable jar with disposable Liner SERRES®
The OB500 LINER is sold with a 1000 ml SERRES® secretions jar equipped with a disposable
bag (Fig.6).
The jar is made of a transparent plastic material (polycarbonate) and can hold a disposable bag
equipped antibacterial and anti-contamination filter. The jar is equipped with an angular junction
placed laterally which allows it to be connected to the suction unit. The filter integrated into the
disposable bag performs the function of preventing the backflow of aspirated liquids towards the
suction unit when it completely fills up, and to avoid cross-contamination. On the top of the
disposable bag there is a white plastic disposable corner joint, which allows to connect standard
suction catheters or cannulas Jankauer.
OB-J collection jar
OB-J includes the jar (1), adaptor for disposable bag SERRES (2) and the fitting "L" (3). The
disposable bag is provided separately. The integrated filter in the bag performs the function of
preventing backflow of aspirated liquid into the suction unit, when it is completely filled.
The OB-J jar can be sterilized by conventional steam autoclave at a maximum temperature of 121
°C and a pressure of 2 bar (200kPa). Every 30 sterilization cycles, the jar should be replaced.
Jankauer suction tube and Finger-typ end-piece
The suction unit is sold complete with a sterile, Jankauer type suction probe which is connected
to a plastic suction tube. The probe and the tube are disposable and must be changed after
each use. To facilitate correct operation, the probe is angled to allow ease of entrance to the
mouth and the respiratory airway.
A different type of suction set, which includes a silicone tube (length 130 cm –51.2 in)
and one Finger-tip sterile joint, is available at customer request. Finger-typ joint allows
the user to control the vacuum by opening or closing a venturi hole with a finger. When
the venturi hole is completely open, the vacuum will operate at the minimum value, with
the venturi hole completely closed the vacuum will operate at the value set on the unit.
Silicone tube is sterilisable, Finger-typ is disposable.
Wall bracket for the jar
The device BSU402 and BSU414 includes one metal bracket, which is necessary for wall mounting
of the bottle jar. The bracket should be installed so as to keep the bottle upright.
The wall bracket is provided with two holes allowing vertical and horizontal adjustment. The best
position, both for its usage and for cleaning and sterilization activities, lies under the control
module. The silicone cable provided with the device may be properly shortened depending on wall
brackets distance from the wall itself.

Rev. 10-2018 USMAN500 - UK
OB500 LINER includes one plastic bracket. The fixing procedure is the same as for OB500 FA.
Power supply
The external power source of the OB500 should be between 12÷15Vdc. Insert in series to the plus wire an appropriate
protection fuse (min. T15A). Check the correctly connections and the insulation of the cable every 2 months. Do not use
the unit if not fixed and not connected to the right power source (12Vdc).
WARNING
Check that the external power source is correctly rated. The external power source has to be protected
by a security fuse with a minimum rating of T15A (delayed type). The mains voltage can be deadly to
humans!
MAINTENANCE AND REUSE
After each reuse
After each use, switch off the suction unit; disconnect the single patient use - disposable parts (e.g. Finger-typ, catheters,
liner etc.) and dispose of them according to local regulations. Check that the suction unit operates correctly - check the
connection tubes and the controls on the front side for damage. Further, inspect the chassis for possible signs of
damage. Clean and disinfect the unit following the instructions in paragraph “Cleaning the unit”. Replace all single use
- disposable parts with new components and recharge the battery. Make a daily function test as described under "Daily
checklist".
Occupational safety and PPE (Current legislation concerning workplace safety and health)
The decontamination process is always a delicate process, which implies a specific training, especially in the field of
emergency, where the patient’s medical condition and contamination level is mostly unknown. For this reason, the user
must always use personal protective equipment (PPE) to protect himself and other people.
In case a proper PPE is not available, please contact the person who is in charge for the workers’ safety in your company
or organisation.

Rev. 04-2010 USMAN2012-IT
