Maintenance - Hologic MyoSure 40-250 Gebrauchsanleitung

ENGLISH
• Flush all lumens of the hysteroscope and removable outflow
channel with warm tap water
• Scrub the hysteroscope and removable outflow channel using
a nylon-bristled brush that is suitable to contact the full interior
dimensions (diameter and length) of the lumens. Scrub all
surfaces, crevices, interior cavities of the stopcock and lumens
to remove any visible debris. Do not scratch any of the optical
surfaces.
• The following brushes dimensions are recommended
• For the main lumen, a nylon-bristled brush with bristle
area length of 2" (50mm), bristle diameter of .236" (6mm) and
an overall length of 14" (35cm) is recommended
• For all other lumens, a nylon-bristled brush with bristle area
length of 2" (50mm), bristle diameter of .197" (5mm) and an
overall length of 14" (35cm) is recommended
• Utilizing the stopcocks, flush the lumens with an enzymatic,
neutral pH cleaner a minimum of three (3) times ensuring that no
air remains within the lumen.
• Hysteroscope, removable outflow channel and accessory
components should be soaked in an enzymatic, neutral pH
cleaner in accordance with cleaning solution instructions.
• Thoroughly rinse the hysteroscope, including flushing all lumens
and accessory components to completely remove the cleaning
solution.
• Dry the hysteroscope with a lint free soft cloth or filtered
compressed air.
• Check visually for cleanliness to ensure that all debris have been
removed. If not visually clean, repeat reprocessing steps until
the device is visually clean.
Hysteroscope Cleaning Instructions—
Optical Surfaces
Due to insufficient cleaning or foreign matter contamination,
deposits may develop on the three optical surfaces of the
hysteroscope as shown below.
These are:
• The distal tip
• The proximal window or eyepiece
• The fiber optic light post

To remove these deposits, a tube of bio-compatible polishing paste
is enclosed with each hysteroscope.
To remove the deposits, dab some polishing paste onto a clean,
cotton-tipped swab. Gently press the swab onto the optical surface
to be cleaned and scrub the surface with a circular motion. Rinse
the optical surface with water to remove any remaining polishing
paste.


NOTE: Cleaning should only be performed when the image as
viewed through the scope is cloudy, and not as part of your
routine cleaning procedures.
NOTE: Do not use any ultrasonic cleaning methods. The energy
transmitted through fluid cavitations will damage seals and
optical surfaces and will void the warranty.
NOTE: Foreign matter remaining on the fiber surface of the
light post after cleaning may tend to burn and discolor the
surface when exposed to a high intensity light source.
Sterilization
Hysteroscope and outflow channel should be sterilized in a
container which secures the instruments in place. Be sure the
distal working length does not experience any undue forces or
stress which can damage the delicate internal optics.
Sterilize the hysteroscope and outflow channel with the following
validated steam autoclave, ethylene oxide (Et0) gas, Sterrad
STERIS Amsco V-PRO
® ®
Ethylene Oxide (100% EtO – wrapped)
Follow standard hospital procedure maintaining the following
parameters:
Temperature:
Relative Humidity:
Gas Concentration:
Exposure Time:
Aeration Time:
Sterrad —Devices meet guidelines for Sterrad 100S, NX, and
®
100NX systems and require the use of a Sterrad-compatible
tray or container systems. Refer to manufacturer's Instructions
for Use for more information. STERIS
meet guidelines for Amsco
maX Low Temperature Sterilization Systems and should use
the STERIS compatible tray or container systems. Refer to
manufacturer's Instructions for Use for more information.
Steam Autoclave Wrapped
Follow standard hospital procedures:
Pre-vacuum method:
Gravity method:
IMPORTANT: It is recommended that the institution employ
procedures which include the use of biological indicators in order
to determine the effectiveness of the sterilization process.

Maintenance

We recommend that you inspect the hysteroscope carefully before
and after the procedure for possible signs of damage.
First, check the image quality of the scope by viewing the monitor.
If image quality is impaired:
• Check the distal and proximal lenses of the hysteroscope for
cracked or scratched lenses.
• Check the surface cleanliness of the distal and proximal lenses.
A foggy or cloudy image can be the result of moisture entering
the optical system or lack of cleanliness of exterior surfaces.
When viewing reflected light, the surfaces should appear smooth
and shiny.
