2 Safety Instructions

Conditioning Information

Attention Risk of injury if the BIOM® 5 is not sterile If the patient or his bodily fluids come into contact with the BIOM® 5, it can become contaminated, e.g. when putting it away. 

Make sure that the BIOM® 5 is cleaned, disinfected and sterilised. Condition the BIOM® 5 before the first and every subsequent use.



Comply with the legal provisions in force in your country, and with the hygiene and waste disposal regulations of the hospital or clinic. Condition the BIOM® 5 only after you have fully understood this instruction manual. The BIOM® 5 and all sterilisable components of the BIOM® 5 must be cleaned, disinfected and sterilised prior to initial use and prior to every subsequent use. To do so, take the BIOM® 5 out of the packaging. Make sure that only validated device and product-specific procedures are used for cleaning/disinfection and sterilisation and that the validated parameters are observed for each cycle. Use a machine (disinfector) for cleaning/disinfection purposes. This is much more effective.

Notes on returning

Attention Personal injury caused by contaminated BIOM® and components 

Before returning the product to OCULUS: Prepare the BIOM® and sterilisable components according to this treatment instructions.  Send only visibly prepared OCULUS products back to OCULUS

5.3 5.3.1

Cleaning/Disinfection by Machine Information About Cleaning/Disinfection by Machine Cleaning/Disinfection Unit (CDU) 

Make sure that the CDU meets the following criteria.

It must have been tested for efficiency (e.g. DGHM I or FDA approval, or CE marking, in conformity with DIN EN ISO 15883-1 )  Use a tested disinfection programme (at least 5 minutes at 90°C) for thermal disinfection, as with chemical disinfection, there is a risk of disinfectant residues being left on the products. The A0 value=3000 must be reached.  Use water of a quality that meets the requirements of DIN EN 285 (including demineralised water with an electrical conductivity of approx. 15S/cm).  Use air that meets the compressed air requirements in a hospital, for drying purposes.  Make sure that the detergent and the disinfectant do not react with each other. 

Also see “Appendix” on page 25 

Regularly inspect and service the CDU in accordance with in-house specifications.

Detergents and Disinfectants 

Make sure that the detergents and disinfectants meet the following criteria.

The detergent (e.g. neodisher MediClean concentration 0.5 %, Dr. Weigert, Hamburg) must:   

Be suitable for cleaning the products. Be compatible with the disinfectant that is used. Be listed with the DGHM (German Society for Hygiene and Microbiology)

Conditioning Instruction BIOM® 5 (G/55185/0818/en)

5 Cleaning and Disinfection

Note Risk of malfunctions and surface damage if alkaline detergents are used. If you use alkaline detergents: 

Properly neutralise after use in accordance with the manufacturer’s specifications.  Check whether the chemicals that are used are compatible with the products. Alkaline detergents can attack the surfaces of the products and lead to malfunctions. If thermal disinfection (at least 5 minutes at 90°C) is not performed, the disinfectant must: Be of a proven efficiency (e.g. have DGHM or FDA approval, or CE marking).  Be compatible with the detergent that is used.  Always adhere to the detergent and disinfectant concentrations specified by the manufacturer. 

Cleaning method The following cleaning method was used for validation of the steamautoclavability of the BIOM optics:

See sect. 12, page 25

5.3.2

Use the cleaning method that meets the requirements of your national standards.

Cleaning and Disinfecting by Machine     

10 / 26

Check whether the components have been pre-cleaned, sect. 5.2, page 8. Place the components of the BIOM® 5 into the disinfector basket or into a sterilisation tray. Secure the loupes in the tray with the holders provided for that purpose. Loose loupes could get scratched. To ensure that the effectiveness of the cleaning/disinfection is not impaired, make sure that the components do not touch each other. Place the disinfector basket or the sterilisation tray with the components in the CDU. For stackable disinfection baskets or sterilisation trays, heed the manufacturer’s instructions.

Conditioning Instruction BIOM® 5 (G/55185/0818/en)

5 Cleaning and Disinfection



☞

To prevent water stains on the optics, keep the loupes and reduction lenses as vertical as possible during the cleaning process.  Start the cleaning programme, see sect. 12, page 25, e.g.:  3 Minute pre-wash cycle with cold water  Empty  Clean for 5 minutes at 55°C with cleaning detergent  Empty  3 Minute rinse cycle with cold, demineralised water  Empty  2 Minute rinse cycle with demineralised water  Empty  At the end of the programme: Remove the disinfector basket or the sterilisation tray from the disinfector.  Check whether the BIOM® 5 needs to be dried with compressed air. 

Conduct a function test before you sterilise the BIOM® 5 with steam, sect. 6.1.1, page 15.

For more information about these jobs, refer to sect. 12, page 25.
