Intended Use

This washer-disinfector can be used to clean, rinse, disinfect (thermally and chemically) and dry a wide range of reusable medical devices.

Follow the manufacturer's instructions (according to EN ISO 17664) on how to process their items by machine.

Examples of application areas:

surgical instruments,

minimally invasive instruments,

anaesthetic and intensive care instruments,

baby bottles and teats,

stainless steel and aluminium containers (including anodised aluminium),

operating theatre shoes.

Processing medical devices by machine achieves reproducible results, and should be used in preference to processing them by hand.

Where disinfection is required for the protection of staff and/or patients, a thermal disinfection programme, e.g. the DESIN vario TD programme, should be selected.

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.

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.

The cleaning result must ensure that the 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 ORTHOVARIO or OXIVARIO programme where applicable.

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).

This machine complies with EN ISO 15883 for validation purposes.
