Instruments
Any deposits such as dental cement, composite, polishing paste or
similar must be removed immediately after examination of the patient,
e.g with a swab, before it hardens.
Instruments with particularly complex functional ends or very stub-
born deposits may require ultrasonic pre-treatment.
To avoid injury from double-ended instruments or upright instru-
ments with upward-facing probes, the washer-disinfector should
be loaded from rear to front, and unloaded from front to rear.
After thermal disinfection, manual secondary cleaning can be under-
taken according to relevant bio-substance regulations without danger
of infection, although the process must be monitored as necessary.
Transmission instruments
Transmission instruments with light guide rods can be regarded as
durable, whereas fibre optic bundles can be susceptible to more
rapid wear.
Use a neutral to mildly alkaline liquid cleaning agent for cleaning.
Where there is build-up of deposits, a citric acid-based neutralising
agent should be dispensed.
The wash fluid must be filtered prior to internal cleaning so that the
narrow channels in transmission instruments do not become blocked
with treatment residues from the wash fluid. The injector basket A 105
should therefore be used for reprocessing transmission instruments,
in conjunction with the re-usable tubular filter A 800 and the holder
for transmission instruments
A 803 or the holder AUF 1.
The injector basket, tubular filter and the holder AUF 1 each come
with their own operating instructions.
After processing dry internal sections of transmission instruments
with sterilised compressed air and then sterilise as required follow-
ing manufacturer's instructions and national health and safety regu-
lations.
Before using transmission instruments again following repro-
cessing, a function check must be carried out, e.g. by spraying into
a basin, to ensure they are clear.
UK only: This washer-disinfector is NOT intended for repro-
cessing transmission instruments such as turbines, hand-pieces
and contra-angles.
