the antibacterial filter, because from a bacteriological point of view, it becomes dangerous for the
patient. Keep the device vertical to allow the overflow to function correctly.
All the components of the vessel can be sterilised using a conventional system in an autoclave at a
temperature of 121° C, or by boiling for 10 minutes. We recommend replacing the complete vessel at every
30 sterilisation cycles. Do not overturn the vessel during use, in order to prevent the intervention of the non-
return valve (3-4-5); should this occur, switch the aspirator off and detach the tube connected to the
antibacterial filter. Never use the aspirator without the secretion collection vessel and/or without the
antibacterial filter.
3.1.1 Connection: connect one end of the short, sterilisable silicon tube (7) to the antibacterial filter connector
(6) and insert this latter into the "VACUUM" hole of the blue top (2); connect the other end to the "INLET"
connector (13) of the aspirator. Connect one end of the long sterilisable silicon tube (8) to the
"PATIENT/PAZIENTE" connector of the blue top (2); to the other end, connect the disposable, sterile manual
regulator (11) and connect the disposable, sterile cannula (10) to this latter.
3.2 Secretion collection vessel with disposable bag (9). The aspirator can be used with the re-usable 1000 ml.
transparent secretion collection vessel (1) and with the disposable bag (9) supplied. In this case, the
antibacterial filter is integrated in the disposable bag and therefore the antibacterial filter (6) and blue top
with valve (2) are not used. The filter integrated in the bag also performs the function of preventing the return
of aspirated liquids towards the aspirator. In this case, to restore device operation, it is necessary to
replace the disposable bag. For the cleaning and disinfecting operations of the tubes (7-8) and vessel (1),
sterilise the single parts in an autoclave at a maximum temperature of 121° C, or by boiling for 10 minutes.
The bag is disposable and must always be replaced after every use. The bag must be completely inserted
in the vessel in order to prevent any vacuum losses.
N.B.: maximum disposable bag usage vacuum: – 0.75 bar (75 kPa).
3.2.1 Connection: connect one end of the short sterilisable silicon tube (7) to the yellow connector (VACUUM)
of the top (photograph 3b) and the other end to the "INLET" connector (13) of the aspirator. Connect one
end of the long sterilisable silicon tube to the red connector (PATIENT) and connect the disposable sterile
manual regulator (11) and the disposable sterile cannula (10) to the other.
N.B.: only use the disposable bags supplied by 3A - Code 3A1687.
4. SECRETION VESSEL - 2000 ml (Fig. 4)
The secretion vessel set consists of an overflow valve, a vessel (1) in clear material (polycarbonate) and a blue
plug (2).
Connection: connect one end of the 10 cm tube (8a) to "VACUUM" connector of the blue top (2) and the other
end connect it to the antibacterial filter connector (7). Then connect one end of the 20 cm tube (8) to the free
connector of the antibacterial filter (7) and the other end to the "INLET" connector (13) of the aspirator.
The antibacterial filter also protects the aspiration circuit from any contaminating agents sucked in during use.
Do not use the aspirator without the antibacterial filter, because from a bacteriological point of view, it becomes
dangerous for the patient. Keep the device vertical to allow the overflow to function correctly.
Connect one end of the 130 cm tube (9) to the "PATIENT" connector of the blue cap (2), while at the other end
to connect the disposable, sterile manual regulator (11) and connect the disposable, sterile cannula (10) to this
latter.
All the components of the vessel can be sterilised using a conventional system in an autoclave at a
temperature of 121°C, or by boiling for 10 minutes. We recommend replacing the complete vessel at
every 30 sterilisation cycles. Do not overturn the vessel during use, in order to prevent the intervention
of the non-return valve (3-4-5); should this occur, switch the aspirator off and detach the tube connected
to the antibacterial filter. Never use the aspirator without the secretion collection vessel and/or without
the antibacterial filter.
The LTA420 is fitted with a LED working light (10) which allows use of the device in dark conditions and/or at
night.
Press the button (11) to switch on the light, as shown in Figure 6 of page 5; press the button (11) again to switch
it off. The light switches off automatically after about 60 minutes.
The light is of LED type, so the amount of current it consumes is minimal and it can be used even during
treatment; however, it should be switched off whenever it is not required and/or at the end of the treatment.
