Cleaning: Manual (continued) e) Dry the probe thoroughly with a disposable wipe and leave to air dry. It is extremely
unlikely that the probe cable will become contaminated; however, if it does,
the same procedure as above can be followed.
f) Reconnect the cable and probe and turn on the C-Trak Apollo System. If the system is still
indicating a high background, turn the system o and repeat the steps above. If the system
still indicates a high background, contact nuclear medicine or biomedical engineering for
evaluation. The probe may have been damaged.
3) Cleaning prior to disinfection or sterilisation
Tristel Trio Method (Step 1: Cleaning)
The Pre-Clean Wipe (CE Marked as a Class I Medical Device) is impregnated
with a triple-enzymatic detergent and surfactant.
a) Disinfect hands and wear gloves when handling disinfectants and medical devices.
b) Take one Pre-Clean Wipe sachet.
c) Remove the Wipe from its sachet and lay it out in the palm of your hand.
d) Wipe the surface of the medical device until soil and organic matter have been visibly removed.
In case of heavy soiling more than one Wipe may be used.
e) Discard the used Wipe and gloves in accordance with local regulations.
Do not reuse. Keep the empty Wipe sachet for traceability.
Disinfection The OmniProbe and cable have been validated against the Tristel Trio Wipes System.
Following Step 1: Cleaning described above, the following steps must be
observed to obtain high-level disinfection:
Tristel Trio Method (Step 2: Activating and High-Level Disinfecting)
The second step in the decontamination procedure is the high-level
disinfection of the medical device.
The Sporicidal Wipe is CE Marked as a Class IIb Medical Device.
a) Disinfect your hands and put on new gloves.
b) Take one Sporicidal Wipe sachet.
c) Remove the Wipe from its sachet and lay it out in the palm of your hand.
Note: Activate the Sporicidal Wipe as soon as you have removed
it from the sachet and use it immediately.
d) Remove the lid from the Activator Foam bottle.
• If you are using Trio Wipes System (50), apply two aliquots
of Activator Foam onto the Sporicidal Wipe.
• If you are using Trio Wipes System (5), apply four aliquots
of Activator Foam onto the Sporicidal Wipe.
Note: If the Activator Foam bottle is being used for the first time, depress the pump two to
four times to prime it. The first output from the foam bottle can be left on the Wipe, to be
followed by complete aliquots. The Activator Foam bottle is then primed for subsequent Wipes.
e) Fold the wipe in on itself and scrunch together for 15 seconds to activate.
Ensure that the Wipe is evenly covered with foam. Use the activated Wipe immediately.
Presence of a chlorine-like odour confirms that the Wipe is ready to use.
f) Wipe the surface of the medical device in one movement to cover it with foam, ensuring all
areas come into contact with the Wipe. Pay special attention to edges, ridges and indentations.
g) Observe a 30-second contact time.
h) Discard the used Wipe in accordance with regulations. Do not reuse.
Keep the empty wipe sachet for traceability.
Tristel Trio Method (Step 3: Rinsing)
The third and final step in the decontamination procedure is rinsing of the medical device. The
Rinse Wipe is impregnated with de-ionised water and a low-level of antioxidant which removes
chemical residues from a surface.
Each Rinse Wipe sachet is packed and then sterilised by gamma-irradiation.
The Rinse Wipe is CE Marked as a Class I Sterile Device.
