Warning
The user of the FX-100 Flexible Sigmoidoscope should be thoroughly
trained in the medical procedures appropriate to the equipment.
Furthermore, time should be taken to read and understand these
instructions before performing any procedures. Instructions for
other equipment used in conjunction with the flexible sigmoidoscope
(e.g. electrosurgical generators, suction machines, snares, etc.)
should also be read and understood. Failure to do so may result in
injury to the patient and/or damage to the instrument.
While this manual describes the recommended protocol for inspecting
and operating the equipment, it does not outline procedure tech-
niques. Only physicians trained and versed in the procedure of flexible
sigmoidoscopy should use this equipment.

Before preparation or set up of the equipment, check all components
received against list of components (see components section) to
verify complete set. If parts are missing, please notify Welch
Allyn.
Review the nomenclature, setup, operation and cleaning/disinfection
sections to become familiar with the equipment.
Specifically, inspect:
Fiber Optic Sigmoidoscope
l Insertion tube
l Control section
to assure smooth rotation of controls
l Biopsy channel
channel to verify smooth passage
-
for tears, cuts, dents, bubbles, bumps
-
depress valves, test bending section deflection
-
pass cleaning brush through biopsy/suction
Light Source
l Cabinet
-
for any dents, scratches or other abnormalities
System Setup
Light Source
Plug the light source into a properly grounded 110-120 volt
AC outlet. Activate power and air switches to verify functionality
of illumination and pump.
Fill water bottle approximately 3/4 full of clean tap water. Replace
and tighten the cap and attach to water bottle bracket on the
right side of light source.
Connect air input hose on water bottle to air output connector on
right side of light source.

NOTE:
use, following the steps starting on page 24 and 35, or in the FX-100
cleaning and disinfection video tape.

Plug endoscope connector terminal into endoscope connector port
of light source. Push gently until it “snaps” into place.
Connect ends of dual lumen air/water line to the color coded
air/water outputs on endoscope connector terminal (White =
Water, Green = Air). Attach remaining end to water bottle. Mount

4. Verify biopsy seal is seated in place over biopsy port opening.

System Inspection
The following steps should be repeated prior to every procedure to
verify that the system is working. If any problem is encountered,
immediately consult the troubleshooting section of this manual or
contact your local Welch
assistance.
Physical Inspection:
Insertion Tube and Bending Section
l Inspect the insertion tube for tears, cuts, dents, bubbles, bumps
or other abnormalities on the surface.
l
Run your fingers carefully over the entire length to check for
protruding braid, internal looseness or other abnormalities.
Allyn
distributor or representative for
CAUTION: Do not wind insertion tube into a tight radius. Serious
damage to internal fibers could result. Proper storage procedures
are outlined on page 50.
Deflection Controls
Operate deflection controls slowly
in all directions. Make sure that
deflection is smooth and that no
friction or grinding is present.
Up/down plane - rotate the up/
down deflection control knob to its
limit in each direction. It should
rotate without excess friction.
l Right/left plane
-
rotate the
right/left deflection control knob to
its limit in each direction. Unlike the
up/down control, a slight resistance
or “drag” should be apparent. This
is a design of the scope that allows
the bending section to remain in
position without holding the control
knob. The bending section should
not lock into position. To verify this,
deflect the control to maximum and
release. The bending section should
return to a straight or neutral posi-
tion by applying gentle pressure with
your index finger.
WARNING: If the resistance in the right/left deflection plane
is higher than normal, DO NOT USE the instrument. Contact
Welch Allyn Customer Service for assistance.
CAUTION: Do not deflect the bending section by hand. This
applies excess force to the deflection mechanism and may
result in failure.
12
Light Source
1. Activate “power” switch. This will start the lamp and cooling fan.
CAUTION: Do not look directly into the endoscope connector
port when activating the light source.
2.
The output of the light source is then controlled by the illumination
intensity control. Clockwise rotation will increase illumination
output. Counter clockwise will decrease illumination.
3. Activate “air” switch. This will start the internal insufflation pump.
Inspection of Air Feed
1.
Place tip of bending section into clear water. Cover hole on top of
air/water valve with finger tip. Do not depress valve. Air should flow
freely through the instrument and water should bubble vigorously.
2. Remove finger - bubbling should end immediately.
13
Inspection of Water Feed
1.
Depress air/water valve completely. Water should flow in a
constant stream over objective lens and light guides.
2.
Release valve - water flow should end immediately.
NOTE: Upon initial setup, depress and hold down valve for a few
seconds for water to completely fill line in instrument.
Inspection of Suction
1.
Verify that suction tubing is attached and suction machine is on.
Immerse tip of bending section into clear water and completely
2.
depress suction valve.
Verify aspiration by viewing water flow into suction receptacle.
3.
Releasing valve should stop suction immediately.
14
Inspection of Manual
Water Feed
1.
Connect manual irrigation
tubing to auxiliary water
inlet on endoscope.
2. Fill syringe with clean tap
water and connect to
remaining end.
3. Feed water through inlet
and verify that it exits from
water nozzle over objective
lens and light guides.
NOTE: If leak occurs at inlet, tighten connector. If leak
continues, call Welch Allyn Customer Service.
Inspection of Biopsy/Suction Channel
1.
Deflect bending section 90o in “up” direction.
2. Pass cleaning brush or forceps through the
biopsy channel to verify a clear pathway.
3. Repeat Steps "1 and 2” in three remaining
directions.
NOTE: If resistance is encountered, DO NOT force. Contact
Welch Allyn Customer Service.

Inspection of Light
Guides and Optics
1.
With lamp on, hold distal tip
approximately 40 mm from
any printed surface.
2. Verify light is being emitted from light guides.
3.
Hold eyepiece to your eye and rotate diopter ring until print is in
focus. Verity focus from 10-40 mm from surface.
Inspection of Umbilical Cord
1.
Check the umbilical cord for cracks, dents, crushed and
twisted areas.
2.
Verify that the endoscope connector terminal’s light guide terminal
fitting is tight and does not move when moderate pressure is
applied.
NOTE:
prior to every use. (Follow steps starting on pages 22 and 47, or
demonstrated in the FX-100 cleaning and disinfection video tape).
Instrument should be cleaned, disinfected and sterilized
