• The red vent flap should always be open (Fig.8)
during direct aspiration with the thick hose (2nd
stage). The suction is built up by closing the vent
duct with the index finger and can also be regu-
lated by opening and closing this duct.
• Should the thick aspiration hose (2nd stage) be
sucked onto the patient's tongue or mucous
membranes, the vent duct in the secretion cap
must be opened by lifting the index finger or the
red vent flap reopened. Suction is then interrupt-
ed immediately and the aspiration hose freed.
Pumping by hand, foot or knee can be contin-
ued throughout.
• During aspiration, the secretion bottle must be
placed or held upright (secretion cap pointing
upward). If nessary, the secretion bottle can also
be held vertically or obliquely, however, the
secretation cap must point upwards.
If the secretion cap is held downwards, the over-
flow protection device seals off the connection
to the vacuum pump. If this happens, you should
hold the secretion cap pointing upwards again
and interrupt the aspiration process for a few
seconds by opening the red vent flap on the se-
cretion cap until the safety ball falls back again.
• Once the secretion bottle is full, the overflow
protection device cuts off the suction process
and the pedal can be operated only with consid-
erable difficulty. The secretion bottle should
then be emptied immediately as follows:
– Remove the secretion cap
– Empty the secretion bottle
– Replace the secretion cap
– Continue to aspirate.
