Maintenance
The patient contact surfaces of mammography equipment are noncritical, and either low level or interme-
diate level disinfection is adequate for routine use. These surfaces are the Bucky/Image Receptor, com-
pression paddles and magnification stands. Other surfaces, such as the face shield, which may have
casual contact with the patient should be considered for intermediate level disinfection.
CAUTION
Improper cleaning methods or the use of certain cleaning and disinfecting agents can
damage the equipment, cause poor imaging performance or increase the risk of electric
shock.
To avoid possible injury or equipment damage:
• Unless specified otherwise, do not use harsh detergents, abrasive cleaners, high alcohol concentra-
tion or Methanol at any concentration. If skin preparations contain high alcohol concentrations, allow
sufficient drying time before applying compression.
• Do not expose equipment parts to steam or high temperature sterilization.
• Never allow liquids to enter the internal parts of the equipment. Do not apply cleaning sprays or liq-
uids directly to the equipment; always use a clean cloth dampened with the spray or liquid. If you
become aware of liquid entry, disconnect the electrical supply and have the equipment checked by
qualified service personnel before returning it to use.
1-3 Patient contact surface cleaning instructions
Patient contact surfaces should be washed with mild soap in lukewarm water. Removable parts that do
not contain electrical components, such as the compression paddles, may be removed from the equip-
ment and immersed if needed. Equipment parts such as the Bucky/Image Receptor that enclose electri-
cal components must not be immersed but rather cleaned with a soft dampened cloth, taking care not to
allow liquids to enter the equipment. Surfaces should be scrubbed as needed using a soft sponge, gauze
or cloth to remove all visible residue. Scrubbing with a soft bristle brush (such as a toothbrush) may be
necessary to reach corners or to remove material that has dried onto the surface. Subsequent disinfec-
tion may not be effective if the surfaces are not thoroughly clean.
Rinse all surfaces with clean water to remove visible soap residue, taking care to avoid liquid entry to
internal equipment parts. Dry surfaces with a soft cloth to remove any visible residue.
1-4 Low level or intermediate level disinfection
Patient contact surfaces may be disinfected with a suitable liquid chemical germicide. Surfaces must first
be cleaned of all visible contamination (see above). The liquid germicide must have a minimum contact
time with the surface to be effective. Equipment parts should be wiped with a wet cloth or sponge as
directed by the instructions for use provided with the germicide. If needed, removable parts not contain-
ing electrical components (compression paddles and magnification stands) can be removed and
immersed. Further rinsing or wiping with clear water and drying with a soft cloth should be done to
remove any germicide residue that may remain. Take care to avoid liquid entry to internal equipment
parts.
1-5 High level disinfection
In the event that you feel a high level disinfection is necessary due to equipment contact with broken
skin, or being used with infected or immune compromised patients, the same patient contact surfaces
may be high level disinfected with a liquid chemical germicide rated for high level disinfection. The same
process used as that for intermediate level disinfection is generally followed; however, the time of con-
tact is usually much longer for high level disinfection.
