Chapter 9 Specification
FLUSHING PUMP OFP-2
53
Pump
operation
Water feed
: controlled by pneumatic footswitch or remotely from endoscope via
compatible OLYMPUS video processor.
Maximum pressure:
Less than 1300 kPa
Flow rate:
variable, controlled from front panel.
Flow rate delivery from the pump will depend on the length and type of OLYMPUS EVIS
EXERA/EXERA II/LUCERA/EUS gastrointestinal/colono/ultrasound videoscope or
EndoTherapy Accessory attached.
The operator must therefore assess the condition of the patient and use clinical judgement
to set the flow rate from the pump to avoid causing patient trauma.
For endoscopes incorporating an auxiliary water channel and using auxiliary water
channel tube MAJ-1608/MAJ-1651
: The flow rate when using the CF-Q180AL should be
approx. 230ml/min when the pump head is new and its flow setting is 9 (maximum). The
flow rate will reduce as the pump head deteriorates.
We recommend flow settings of 1 - 6 for auxiliary water channel use.
For instrument channel flushing (1):
The flow rate when using the CF-Q260AL/DL
(3.2mm diameter channel) without an instrument inserted should be approx. 785ml/min
when the pump head is new and its flow setting is 9 (maximum). The flow rate will reduce
as the pump head deteriorates.
We recommend flow settings of 5 - 9 for instrument channel use.
For instrument channel flushing (2):
The flow rate when using the GIF-Q260 (2.8mm
diameter channel) with a 2.5mm diameter ultrasound probe inserted should be approx.
100ml/min when the pump head is new and its flow setting is 9 (maximum). The flow rate
will reduce as the pump head deteriorates.
We recommend flow settings of 5 - 9 for instrument channel use.
For EndoTherapy device flushing :
The flow rate when using the single-use
electrosurgical knife KD-655U should be approx 45ml/min when the pump head is new and
its flow setting is 5.
The flow rate will reduce as the pump head deteriorates. We recommend flow settings of
1-5 for EndoTherapy device use.
If the pump is connected to any other endoscope or device other than those specified in
these instructions, then damage to the pump or attached device, or injury to the patient or
user may result.
Water
container
The water container supplied with the unit has a 2 litre capacity and will withstand a
minimum of 144 steam sterilisation cycles up to 137
°
C for 3 minutes duration.
