1.4 Precautions

Chapter 1 General Policy

• An insufficiently cleaned, disinfected, or sterilized endoscope

and/or accessories may pose an infection control risk to the

patients and/or operators who contact them.

• All disinfection methods (whether performed manually or by
an automated endoscope reprocessor), and all sterilization

methods (whether performed by ethylene oxide gas or

steam) require thorough prior cleaning of the instrument

being reprocessed. If the equipment is not adequately
cleaned prior to disinfection/sterilization, these processes will

be ineffective. Immediately after each patient procedure and

before disinfection/sterilization, thoroughly clean the
endoscope and the accessories used with the endoscope.

• All channels of the endoscope, including the instrument

channel and all accessories used with the endoscope during

the patient procedure, such as all valves, must be cleaned
and high-level disinfected or sterilized after each patient

procedure, even if the channels or accessories were not

used during the patient procedure. Insufficient cleaning and
disinfection or sterilization of these components may pose an

infection control risk to patients and/or operators.

• Disinfectant solutions are hazardous. After disinfection, rinse

all external surfaces and channels of the endoscope and
accessories thoroughly with water to remove residual

disinfectant solution.

• The results of sterilization depend on various factors. These

factors include how the equipment was packaged, and the
placing and loading of the package in the sterilization device.

Verify the sterilization process using biological and/or

chemical indicators. Follow the guidelines for sterilization
issued by national authorities, professional organizations and

infection control professionals, as well as the instruction

manual for the sterilization device.

EVIS EXERA II TJF TYPE Q180V REPROCESSING MANUAL

Chapter 1 General Policy

Leakage tester

• Establish an internal system of identifying contaminated
versus reprocessed endoscopes and accessories to prevent

both mix-ups and cross-contamination. Touching a

reprocessed endoscope and/or accessories with
contaminated gloves or placing them on a contaminated

hanger or surface, including letting them touch the floor, will

recontaminate them.

• Prior to each patient procedure, confirm that the endoscope
and accessories have been properly reprocessed and stored.

If there are any doubts or questions, reprocess them again

before the patient procedure, following the instructions given

in this manual.

• Perform a leakage test on the endoscope after each
precleaning procedure. Do not use the endoscope if a leak is

detected. Use of an endoscope with a leak may cause a

sudden loss of the endoscopic image, damage to the
bending mechanism, or other malfunctions. Use of a leaking

endoscope may also pose an infection control risk.

Figure 1.1

• Store alcohol in an airtight container. Alcohol stored in an

open container may cause a fire hazard and may result in a

loss of efficacy due to evaporation.

EVIS EXERA II TJF TYPE Q180V REPROCESSING MANUAL

Chapter 1 General Policy

AW channel cleaning
adapter (MH-948)

• Do not use the AW channel cleaning adapter (MH-948) for

patient procedures. It will cause continuous insufflation and

could result in patient injury.

Figure 1.2

• The accessories listed on the front cover of this manual are

consumables, meaning that these accessories cannot be

refurbished or repaired and are intended to be replaced once

they show any signs of wear. Should any irregularity be
observed, use a replacement accessory instead. Using

defective accessories may cause equipment malfunction,

reduce the efficacy of reprocessing, present a risk to patients
and/or operators, or damage the endoscope and/or

accessories.

• Single-use brushes, such as the single use channel cleaning

brush (BW-201T), the single use combination cleaning brush
(BW-412T), the single use channel-opening cleaning brush

(MAJ-1339), and the single use soft brush (MAJ-1888), are

designed for cleaning only one endoscope and its related
accessories. Dispose of the single-use brush immediately

after use. Using a single-use brush to clean multiple

endoscopes and/or accessories may reduce its cleaning
efficacy and may damage the brush leading to brush

breakage or endoscope and/or accessory damage.

EVIS EXERA II TJF TYPE Q180V REPROCESSING MANUAL

Chapter 1 General Policy

• Patient debris and reprocessing chemicals are hazardous.
To guard against contact with dangerous chemicals and

potentially infectious material, wear appropriate personal

protective equipment during cleaning, disinfection, and
sterilization. Such protective equipment should include

appropriate eyewear, face mask, cap, moisture-resistant

clothing, shoe covers, and chemical-resistant gloves that fit
properly and are long enough to prevent skin exposure.

• The reprocessing room must be adequately ventilated.

Adequate ventilation protects against the buildup of toxic

chemical fumes.

• Always remove contaminated personal protective equipment

before leaving the reprocessing area to prevent
contamination from spreading.

• Only Olympus-recommended or Olympus-endorsed

automated endoscope reprocessors (AERs) have been

validated by Olympus. When using an AER that is not
recommended by Olympus, the manufacturer of the AER is

responsible for validating compatibility of the AER with each

Olympus endoscope and accessory.

• Before using an AER, confirm that it is capable of
reprocessing the endoscope including all channels, the

forceps elevator recess, and accessories. Be sure to attach

all required connectors. Otherwise, insufficient reprocessing
may pose an infection control risk. If you are uncertain as to

the ability of your AER to reprocess the endoscope including

all channels, the forceps elevator recess, and accessories,
contact the manufacturer of the AER for specific instructions

and information on compatibility and required connectors.

When you use an AER which allows you skip some steps in
precleaning and manual cleaning of endoscopes, confirm

with the AER manufacturer that such skip is applicable to this

endoscope and establish detailed precleaning and manual
cleaning procedures of this endoscope according to both

instructions of this manual and the AER manufacturer.

• Put the forceps elevator in intermediate position of the range

of movement by turning the elevator control lever and set it in
your AER.

Creutzfeldt-Jakob disease (CJD), cannot be destroyed or

inactivated by the cleaning, disinfection, and sterilization

methods stated in this instruction manual. When using the

endoscope and accessories on patients with CJD or variant
Creutzfeldt-Jakob disease (vCJD), be sure to use them for

such patients only, or immediately dispose of them after use

in an appropriate manner to prevent the usage of exposed
devices on other patients. For methods to handle CJD, follow

the respective guidelines in your country.

• The endoscope and accessories may be damaged by

published methods for destroying or inactivating prions. For
information on the durability of Olympus equipment against a

particular reprocessing method, contact Olympus. In general,

Olympus cannot guarantee the effectiveness, safety, and
durability of cleaning, disinfection, or sterilization methods

not described in this reprocessing manual. If you chose to

use a reprocessing method not recommended in this manual,
the local institution and/or physicians must assume

responsibility for its safety and efficacy. Make sure to

carefully inspect each piece of endoscopic equipment for
irregularities (damage) prior to each patient procedure. Do

not use the equipment if any irregularity is found.

• Good quality control practices typically require appropriate

documentation. Items such as local SOPs (standard
operating procedures), confirmation of operator training,

routine testing of the disinfectant’s MEC (minimal effective

concentration), confirmation of the disinfectant’s use-life,
etc., should be documented as performed.

sterile packaging and wraps according to national guidelines.

Chapter 1 General Policy

1.7 Reprocessing before patient procedure

• Improper storage practices, such as not thoroughly drying

external and internal surfaces (lumens) including the forceps

elevator recess prior to storage, will lead to an infection
control risk.

• Improper handling, such as touching a reprocessed

endoscope and/or accessories with contaminated gloves,

placing a reprocessed device on a contaminated hanger or
surface, allowing devices to touch the floor, etc., will

recontaminate the device.

Some national or professional guidelines recommend

reprocessing endoscopes prior to their first use of the day.

Confirm that the endoscope and accessories have undergone proper

reprocessing following their last use and that they have been stored properly.
Check the storage period of reprocessed endoscopes, and check for surface

contamination (e.g., dust). Check the sterilization expiration date(s) of all items

so marked and for tears or breaches in sterile packaging. If there are any doubts
or questions concerning whether a device is contaminated, reprocess it again

3.1 Compatibility summary

The endoscope and accessories are compatible with several methods of

reprocessing. However, not all reprocessing methods are compatible with all
endoscopes and all accessories. Reprocessing with incompatible methods can

cause equipment damage even if the number of reprocessing cycles is small.

For appropriate reprocessing methods, see Table 3.1.

Follow the policies at your local institution when choosing which methods listed
in Table 3.1 to employ.

• Methods listed as “compatible” in Table 3.1 are compatible

for routine use only when used according to manufacturer’s
instructions. Repeated use and reprocessing of endoscopes

and accessories leads to gradual wear and tear. But

reprocessing methods that employ higher temperatures and
more caustic/corrosive materials may lead to faster

deterioration. In general, sterilization processes are harsher

on equipment than disinfection processes. Before each
patient procedure, inspect the endoscope and accessories

for damage, according to the instructions described in this

manual and its companion “OPERATION MANUAL”.

• Instructions provided in this manual regarding material
compatibility are not valid for Olympus devices repaired by a

non-Olympus facility. Olympus repairs devices to

manufacturer’s specifications using original equipment
manufacturer’s (OEM) materials. The use of non-OEM

materials to repair an Olympus device may affect the material

compatibility of the device with certain reprocessing
chemicals or methods. In the event that your device has

been repaired by a non-Olympus facility, contact that repair

facility for instructions regarding material compatibility.

Certain accessories are required to manually reprocess the endoscope. Some of

these accessories are cleaned and disinfected along with the endoscope. The

steps for reprocessing the endoscope and these accessories are explained in
this chapter. Chapter 6, “Reprocessing the Accessories” describes the steps for

reprocessing accessories that are not reprocessed together with the endoscope.

The reprocessing workflow of all accessories is outlined in Chapter 4,

“Reprocessing Workflow for the Endoscope and Accessories”.

Figure 5.1

The TJF-Q180V endoscope has a forceps elevator. The

surface and surrounding area of the forceps elevator, such as
the groove, guidewire locking groove, and forceps elevator

recess, have a complex shape. Reprocess these parts

carefully following the procedure described in Chapter 5.
Insufficient reprocessing may pose an infection control risk to

patient and/or operators.

Bending section

Insertion section

Insertion tube

Distal end

• The insertion section of the endoscope is composed of the
insertion tube, the bending section, and the distal end. The

bending section is covered by a thin, easily damaged elastic

covering. Do not allow reprocessing equipment to forcefully
contact the bending section. Do not allow any sharp edges,

such as the distal ends of EndoTherapy accessories

(needles, forceps, snares, etc. used in the instrument
channel of the endoscope) to contact the bending section.

Such improper handling may damage the covering and

cause the endoscope to leak.

Figure 5.2

• Handle the insertion section carefully. Tightly gripping or

sharply bending the insertion tube or the bending section can

stretch or severely damage the insertion tube and/or the
covering of the bending section.

• To prevent damage to the endoscope, do not immerse the

endoscope with objects other than the equipment used for

reprocessing the endoscope.

• To prevent damage, do not coil the insertion tube or the
universal cord of the endoscope with a diameter of less than

12 cm.

Use sterile equipment, such as sterile syringes and cloths, for all reprocessing

steps occurring after immersion of the endoscope and accessories in

disinfectant solution.

Perform the leakage test

• If you identify a leak during leakage testing, remove the

endoscope from the water with both the water resistant cap
(MH-553) and the leakage tester (MB-155) still attached.

Contact Olympus regarding instructions for reprocessing a

leaking endoscope in preparation for returning the
endoscope to Olympus for repair.

• Do not attach/detach the water resistant cap or the leakage

tester while immersed. Attaching/detaching under water

could allow the water to enter the endoscope, resulting in

endoscope damage.

• When attaching the connector cap of the leakage tester to

the venting connector of the water resistant cap, make sure

that both the connector cap and the venting connector are

thoroughly dry. Water on the surface of either component
may enter the endoscope and could cause endoscope

damage.

• When attaching the connector cap of the leakage tester to

the venting connector of the water resistant cap, push on and
rotate the connector cap clockwise fully until it stops. If it is

not fully and properly attached, the interior of the endoscope

will not be properly pressurized and accurate leakage testing
will be impossible.

• Detach the leakage tester from the maintenance unit (MU-1)

or the light source before detaching the leakage tester from

the water resistant cap. If the leakage tester is detached from
the water resistant cap before detaching the leakage tester

from the maintenance unit or the light source, the air

pressure inside the endoscope will not vent properly. This
may damage the endoscope.

• A continuous series of air bubbles emerging from any

location on the endoscope indicates a leak at that location. If

there is a leak in the instrument channel or suction channel of

the endoscope, a continuous series of air bubbles will
emerge from one or more channel openings (e.g., distal end,

suction connector, suction cylinder, instrument channel port)

on the submerged endoscope.

• The channel cleaning brush (BW-20T) is consumable. The
single use channel cleaning brush (BW-201T) and the single

use combination cleaning brush (BW-412T) are for single

use. Repeated usage of these brushes may cause the brush
head to become bent or kinked, which could cause it to come

off during use. Confirm that the brush is free from any

damage or other irregularities before and after use. If a piece
of the brush comes off inside the endoscope channel,

immediately retrieve it. Confirm that no parts remain inside

either the instrument channel or the suction channel of the

endoscope by carefully passing a new brush through both
channels. Any part left in the channels can drop into the

patient during a subsequent patient procedure. Depending

on the location of the missing part, the part may not be
retrievable by passing a new brush. In this case, contact

Olympus.

• Do not attempt to pass the channel cleaning brush or the
single use channel cleaning brush backwards – i.e., by

inserting the brush directly into the open end of the

instrument channel at the distal end of the endoscope’s
insertion section or directly into the suction connector on the

endoscope connector. It may get caught, making retrieval

impossible.
