Intended Use
Re-usable medical devices, laboratory equipment and accessories can be cleaned, rinsed, disinfected and dried in this Miele washer-disinfector. Follow the medical device and laboratory equipment manufacturer's instructions (according to EN ISO 17664) and local and national regulations and guidelines, on how to reprocess their items by machine.
Examples of application areas:
–surgical instruments,
–with the Vario-TD programme: minimally invasive instruments can be processed immediately after being used,
–anaesthetic and intensive care instruments,
–baby bottles and teats,
–operating theatre shoes,
or
–laboratory equipment used in research and development,
–laboratory equipment used in areas of analysis and specimen taking,
–laboratory equipment used in micro-biology and biotechnology.
The type of laboratory equipment which can be processed ranges from evaporating dishes to centrifugal test tubes.
Reprocessing medical devices and laboratory equipment by machine achieves reproducible results, and should be used in preference to reprocessing them by hand.
Where disinfection is required for the protection of staff and/or patients, carry out thermal disinfection using e.g. the DESIN vario TD programme.
- Except for operating theatre (OP) shoes which are not heat-resistant, for which the CHEM-DISIN programme should be used.
The parameters for thermal disinfection according to EN ISO 15883-1 (A0 concept) vary depending on the disinfection standard required. They are 80 °C (+ 5 °C, - 0 °C) with a 10 min holding time (A0 600) or 90 °C (+ 5 °C, - 0 °C) with a 5 min holding time (A0 3000). An A0 value of 3000 is suitable for deactivating the HBV virus.
National health and safety regulations regarding disinfection must also be observed (CfPP 01-01, Part D and Harmonised EU Norm EN 15883-2 in the UK).
The cleaning programme as well as any chemical agents must be chosen according to the type of soiling and load being processed.
The agents used for processing the products should be selected to suit the level of cleaning required as well as the method of analysis used.
11
Intended Use
The cleaning result must ensure that instruments can be disinfected correctly, that no residues are left behind, that subsequent sterilisation can be carried out and that the instruments can be used again safely. Medical devices are best processed using the DESIN vario TD programme, or the OXIVARIO programme where applicable.
Programmes OXIVARIO PLUS and OXIVARIO are available for the OXIVARIO process.
The DOS 2 dispensing system is used for dispensing the H2O2 solution.
These cleaning processes use hydrogen peroxide under alkaline conditions to oxidise and remove protein soiling. The cleaning agent used must be tenside free and have a pH value of between 11 and 11.5.
The OXIVARIO procedure has an alkaline main wash making it particularly suitable for the processing of surgical instruments where existing procedures are not satisfactory. It is also suitable for reprocessing instruments used in high frequency surgery, orthopaedic surgery and for instruments that cannot be processed immediately after use.
The OXIVARIO PLUS programme is recommended for preventing the iatrogenic spread of CJD.
The cleaning process is gentle enough for instruments used in minimally invasive surgery, including fibre optics, where the manufacturer has declared that they are suitable for processing with an alkaline cleaning agent.
It is not suitable for anodised aluminium.
Be aware that items made from alloys containing titanium such as some implants, do not always state the material's compatibility. Processing such items can result in colour changes, rendering any coding on them ineffective. If in doubt please consult the manufacturer of the item.
Due to the high efficacy of the Oxivario process it is important to lubricate joints and contact parts on instruments pre sterilisation. Please refer to the instrument manufacturer for guidance.
The use of a suitable carrier (mobile unit, module, insert etc.) is important to ensure the adequate cleaning of the load. Examples are given in the section "Areas of application".
The washer-disinfector is programmed to carry out the final rinse with mains water or with processed water of a quality to suit the application (e.g. aqua destillata, purified water, de-ionised water, demineralised water).The water quality is of particular importance for applications requiring analytically clean laboratory glassware.
This machine complies with EN ISO 15883 for validation purposes.
Optional:
- DOS 4 for retro-fitting
