This Miele washer-disinfector is designed to clean, rinse, disinfect
and dry re-usable medical devices, laboratory equipment and
accessories from these areas. Always comply with the manufacturer's
instructions for the particular medical devices (EN ISO 17664; CAN/
CSA-Z17664) as well as for the laboratory equipment.
Typical applications include:
– surgical instruments,
– minimally invasive instruments,
– instruments for anaesthetics and intensive care,
– baby bottles and teats,
– OR shoes
– rigid sterilization containers made of stainless steel and aluminum
(including colour anodized aluminum),
– laboratory equipment used in research and production
– laboratory equipment for analytical and preparation applications
– microbiology and biotechnology laboratory equipment
Laboratory equipment includes devices from beakers, bottles,
centrifuge tubes, Erlenmeyer flasks, funnels, pipettes, Petri dishes
and round bottom flasks.
Medical devices, laboratory glassware and laboratory utensils for
reprocessing are referred to as the wash load if they are not more
closely defined.
Reprocessing instruments or laboratory equipment by machine
achieves reproducible results and should be used in preference to
processing by hand. Where disinfection is required to protect staff
and/or patients, a thermal disinfection program, e. g. the DES-VAR-
TD program, should be selected.
According to the A0 concept described in EN ISO 15883-1 (CAN/
CSA-Z15883-1-09), thermal disinfection occurs at 80°C (+ 5 °C, - 0
°C) with 10 min holding time (A0 600), or at 90°C (+ 5 °C, - 0 °C) with
5 min holding time (A0 3000), depending on the disinfection result
required. The efficacy standard A0 3000 includes the inactivation of
the Hepatitis Virus.
Regional and/or other official directives may apply (e. g., CSA Z314.8
Decontamination of reusable Medical Devices).
The cleaning parameters should be optimally matched to the type of
soiling and load being processed.
The processing chemicals used for reprocessing the products should
be selected to suit the particular cleaning needs, and where
applicable, to the analysis / analytical methods involved.
