2. CLEANING:
The endoscope has three optical surfaces that must be
cleaned and inspected routinely to ensure both maximum
transmission of illumination and a high quality image.
All optics and surfaces of the scope should be cleaned with
warm water and a pH-neutral cleaning and disinfecting
solution recommended for reprocessing medical
endoscopes. Remove the light post fittings and let the
endoscope soak inside the pH-neutral solution. Closely follow
the manufacturer’s instructions for appropriate chemical
concentrations and immersion time. Thoroughly rinse the
endoscope and fittings to remove the cleaning solution. After
the scope and fittings are dry, inspect the instrument for any
remaining stains. It is important to closely check the three
optical surfaces, as detailed above, to ensure that proper
cleaning has been achieved for optimum performance.
Note: Never clean and/or sterilize endoscopes together with
other instruments unless they are individually secured within a
specialized cleaning container.
Removing stains or deposits on optical surfaces:
Insufficient cleaning or foreign matter in steam during
autoclaving process may leave deposits on any of the three
optical surfaces of the endoscope. If stains or particles are
still present on any of the optical surfaces after cleaning, use
an enzymatic solution together with a clean gauze cloth or
cotton swab and gently clean the optical surface in circular
motions. Rinse the optical surfaces with distilled water to
remove any remaining enzymatic solution. If stains or particles
persist, repeat the previous steps with a mixture of (1:1)
isopropyl alcohol to acetone applied to a fine woven cloth or
lens tissue for gentle cleaning. Rinse again with distilled water
and carefully dry with a soft woven cloth or lens tissue.
If stains, particles or mineral deposits still persist after
following the previously described steps, use the polishing
paste (see below cautionary note) which is enclosed with each
endoscope. Apply a small amount to a cotton swab and gently
clean/polish the optical surface in circular motions. Rinse the
optical surfaces with distilled water to remove any remaining
polishing paste and carefully dry with a soft woven cloth or
lens tissue.
Note: Cleaning with a polishing paste should not be a part of
your routine cleaning procedures and should only be applied
when the image is cloudy due to deposits on the optical surfaces.
Check each optical surface with reflective light for foreign
particles and scratches that could have a negative effect on
the image quality.
Warning: Never use Ultrasonic Cleaners which will damage the
optical system.
Warning: Prior to autoclaving and due to the extreme steam
temperatures, be sure to follow the previous instructions to
remove foreign particles and debris so that they do not harden
onto the optical surfaces.
3. CHEMICAL DISINFECTION AND STERIS ® PROCESS
Miltex ® scopes can be immersed and disinfected using processes
and chemical solutions clearly approved for use on endoscopes.
Always follow individual chemical manufacturer instructions
for proper use. The scopes are materially compatible with the
Steris
® sterilization process. The endoscopes should be rinsed
after soaking with sterile water and dried with a sterile cloth.
4. STERILIZATION
Important: Be sure that the scope is cleaned thoroughly before
sterilizing. Never clean and sterilize endoscopes together with
other instruments unless they are individually secured within a
specialized cleaning container. Endoscopes should be
sterilized in containers that are specifically designed for the
purpose of sterilization. Unless otherwise noted, it is NOT
recommended to wrap endoscopes in towels. Towels may
leave residue on the optical surfaces of the instrument.
4.1. GAS STERILIZATION
Follow standard hospital procedure for gas sterilization. Place
scopes separately from other instruments in a container
approved for general use with gas sterilization (such as
perforated metal tray).
Note: Verify that there is NO contact between the endoscope
and any other metal parts during the sterilization process.
This will result in direct heat transfer from the tray to the
instrument. Use gauze or loosely woven cloth inserts folded
around each item to prevent contact with metal surfaces and
to avoid movement during sterilization.
