Chapter 4 Operating instructions
FLUSHING PUMP OFP-2
34
NOTE
• The tubes and the endoscope's auxiliary channel, instrument channel or
EndoTherapy accessory, must be full of water for it to exit from the
device. Continue to hold down the footswitch while this is happening.
• You can reduce the time it takes for water to start exiting from the
endoscope or EndoTherapy device by pressing the footswitch while
pushing down the pump head lever with your finger.
• Take care not to spray water over equipment, patient or operator when
operating the OFP-2 with the endoscope or EndoTherapy device
outside the patient.
• It may be found that the pump head moves from side to side during
operation. This is perfectly normal and is indicative of the pump head
attachment method.
• The MAJ-1681 and MAJ-1682 tube sets must be primed with sterile
saline in order to fully expel the air already in the tubing. During this
time, the tubing check valve may “whistle” until the air has been
expelled. This is correct operation and not a malfunction.
3.
Press the
flow rate control to minimize the flow rate.
WARNING
For safety reasons, start the water flow at the minimum level and
increase it progressively until the appropriate level for the patient's
condition has been identified.
4.
During the endoscopic procedure, adjust the flow rate using the
and
flow rate controls
on the front panel. When flushing with an instrument channel, use air suction to remove
water from the instrument channel.
5.
Insert the endoscope into the patient after you have completed the necessary preparations in
accordance with the endoscope manual.
6.
While using the OFP-2 on a patient, adjust the flow rate using the
and
flow rate controls
on the front panel.
WARNING
• The operator must assess the condition of the patient and use clinical
and professional judgement to set the flow rate from the pump to a
suitable level to avoid patient trauma. Vigorous flushing may cause
bleeding from lesions or blood vessels.
• The flow control should always be set to minimum at the start of a
procedure and be increased progressively to a level commensurate with
the clinical condition of the patient.
• When flushing with ø2.0 to ø2.2mm instrument channel videoscopes,
remove the EndoTherapy instrument from the MAJ-1606. Otherwise,
leakage or spraying of potentially contaminated fluid may occur. With an
EndoTherapy instrument inserted in the instrument channel, do not flush
and extract at the same time, as there is a potential risk of spraying.
