Appendix A
Care and Maintenance
Th
e probe connectors must be kept clean and free from dust. Connectors
should be inspected before each use. Dust can be removed from the
connectors using an air-duster.
Th
e integrity of probes may be checked by holding the probe end to a source
of bright diff use light, for example a lamp, and inspecting the connector end.
Two bright spots of light of equal intensity should be visible from the pins
within the connector.
Storing the Probes
When not in use, probes should be stored either in the probe box or, following
sterilization, stored unopened in the packaging in which they were sterilized.
Probes should be stored with the optical fi ber coiled neatly.
Cleaning
Probes are cleaned prior to packing and dispatch. It is recommended that the
probe end on all new probes be wiped with a soft cloth, preferably one that
does not shed fi bers, impregnated with 70% alcohol in water.
It is recommended that aft er use probes are cleaned immediately as it is
easier to remove soiling and particulate matter before it dries onto the probe
surfaces.
1. Visually inspect the probe end, cable and connector. If there is
no visible soiling, wipe the probe end and cable with a soft cloth
impregnated with 70% alcohol in water. Allow the alcohol to dry
completely before using the probe.
2. If there is visible soiling, clean the probe with warm water containing
a mild detergent.
3. Careful rubbing with a soft cloth or brush should be employed to
ensure that all soiling and particulate matter is removed. Th
ese actions
should be carried out beneath the surface of the cleaning solution.
Note:
Avoid immersing the probe connector in the cleaning solution.
4. Rinse the probe end and cable in clean water.
5. Wipe the probe end and cable with an absorbent cloth and leave the
probe to dry completely.
