CATH LAB (Azurion 7 M12)
Insufficient cleaning of residues that remain on the equipment after procedures may lead to
patient infection from polluted parts. Ensure that the system is thoroughly and extensively
cleaned after each intervention. When cleaning and disinfecting the system, follow these
general guidelines:
● Use sterile covers to prevent pollution or contamination of the equipment.
● Do not allow liquids to enter the system. This may cause corrosion or electrical damage.
● Do not apply cleaning liquid or spray directly onto the system. Always use a cloth
dampened with the cleaning product.
● Switch the system off prior to cleaning and disinfecting to avoid electric shock or
accidental activation of X-ray. Be aware that even when the system is switched off, live
voltages may still be present on some interfaces.
● The patient straps and ratchet compressor band should be laundered instead of
subjected to surface disinfection.
● Do not use corrosive or abrasive agents or pads.
● Some cleaning agents or disinfection agents may cause discoloration.
● When cleaning scratched or worn painted surfaces, it is to be expected that some
additional paint is removed.
● Before cleaning the mattress, close the air plug to prevent liquids from entering. After
cleaning the mattress, open the air plug to allow the mattress to expand and contract
properly when the patient is positioned on it.
NOTE You should always comply with local instructions, regulations, and guidelines concerning
hygiene.
These cleaning and disinfecting instructions only apply to the X-ray system and do not apply to
other equipment in the room. If cleaning or disinfecting is needed at the interface of third-party
equipment with the X-ray system, dismount the equipment before cleaning or disinfecting. You
should also dismount third-party equipment if you need to clean or disinfect it with agents that
are not compatible with the X-ray system.

NOTE Always follow the manufacturer's instructions for the cleaning agents or disinfectants that
you use
Cleaning
Clean the system as needed with a damp cloth and a detergent solution to remove all visible
residues. 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.
NOTE When cleaning in the vicinity of the X-ray equipment of an OR system, you should leave
the non-sterile covers attached.
Disinfecting
Disinfection may not be effective if the surfaces are not thoroughly cleaned first. Ensure that all
surfaces are cleaned and residues of cleaning agents are removed with water.
To ensure the effectiveness of disinfection, always follow the instructions of the disinfection
product used.
After disinfecting, ensure that no residue disinfection agent remains on the equipment.
It is recommended that any disinfection product is first tested on small areas of the system that
are not visible to verify compatibility.
Disinfectant Agents
You can disinfect the system parts and accessories in the examination room using cleaning
agents consisting of the following disinfectant compounds (note the exceptions that follow this
list). These compounds have been tested for compatibility with the system:
● Ethyl or isopropyl alcohol (95%)
● Quaternary ammonium (300 ppm)
● Glutaraldehyde (2%)
● Ortho-phthalaldehyde (0.55%)

● Hydrogen peroxide (5%)
● Chlorhexidine (0.5%) in ethanol or isopropyl alcohol (70%)
● Sodium hypochlorite (500 ppm)
Be aware of the following exceptions:
● The cover of the mattress is not resistant to chlorine-based detergents.
● The cover of the table tilt movement is not resistant to alcohol-based disinfectants.
● The cover of the MCS frame is not resistant to alcohol based disinfectants.
The following active compounds may not be used:
● Products containing phenol-based components, such as ortho-phenylphenol,
ortho-benzyl-parachlorophenol, or chloroxylenol.
● Products containing fluids such as ether, white spirit, turpentine, trichloroethylene, and
perchlorethylene.
The safety data sheets of a disinfectant product provide detailed information on its composition.
These data sheets can be obtained from the manufacturer of the product.
Using Disinfectant Sprays
Disinfecting a medical equipment room using disinfectant sprays is not recommended. Vapor
can penetrate the equipment causing corrosion or electrical damage. However, if you do use
disinfectant sprays in the vicinity of the X-ray equipment, follow this guidance:
● Do not use flammable or potentially explosive disinfectant sprays. The resulting vapor
could ignite, causing injury to staff or damage to equipment.
● If you intend to use non-flammable, non-explosive disinfectant sprays, first switch off the
equipment and allow it to cool down. This prevents convection currents drawing
disinfectant vapor into the equipment.
● You must cover the equipment thoroughly with plastic sheeting before using disinfectant
sprays.
● When all traces of disinfectant vapor have dispersed, you can remove the plastic
sheeting and disinfect the equipment in the recommended way.
Cleaning the Ceiling Rails

The ceiling rails should be cleaned according to the planned maintenance program to prevent
dust and debris from being released from the rails and polluting the air flow around the table.
Polluted air and contaminated parts of the X-ray system may infect the patient.
1. Clean the ceiling rail track to remove dirt. Insufficient cleaning may result in clots of dirt
that degrade the performance of longitudinal movements.
2. When present, check the fixation of the longitudinal brake strip and clean the strip with
alcohol.
