Preparations at the place of use ► If applicable, rinse non-visible surfaces preferably with deionized water, with a disposable syringe for example. ► Remove any visible surgical residues to the extent possible with a damp, lint-free cloth. ► Transport the dry product in a sealed waste container for cleaning and disinfection within 6 hours.

Cleaning/disinfection Product-specific safety notes on the reprocessing procedure

CAUTION

Symbols on product and packages Caution, general warning symbol Caution, see documentation supplied with the product

Damage to the product due to inappropriate cleaning/disinfecting agents and/or excessive temperatures! ► Use cleaning and disinfectant agents in line with the manufacturer's instructions that are approved for stainless steel. ► Observe specifications regarding concentration, temperature and exposure time. ► Do not exceed the maximum allowable temperature of 96 °C.

► Use suitable cleaning/disinfecting agents if the product is put away in a wet condition. To prevent foam forma-

tion and reduced effectiveness of the process chemicals: Prior to mechanical cleaning and disinfection, rinse the product thoroughly with running water. ► Carry out ultrasound cleaning:

– as an effective mechanical supplement to manual cleaning/disinfecting. – as a pre-cleaning procedure for products with encrusted residues, in preparation for mechanical cleaning/disinfecting. – as an integrated mechanical support measure for mechanical cleaning/disinfecting. – for additional cleaning of products with residues left after mechanical cleaning/disinfecting.

Validated reprocessing procedure General safety instructions Note Adhere to national statutory regulations, national and international standards and directives, and local, clinical hygiene instructions for sterile processing. Note For patients with Creutzfeldt-Jakob disease (CJD), suspected CJD or possible variants of CJD, observe the relevant national regulations concerning the reprocessing of products.

Manual cleaning/disinfection ► Prior to manual disinfecting, allow water to drip off for a sufficient length of time to prevent dilution of the dis-

infecting solution. ► After manual cleaning/disinfection, check visible surfaces visually for residues. ► Repeat the cleaning /disinfection process if necessary.

Note Mechanical reprocessing should be favored over manual cleaning as it gives better and more reliable results. Note Successful processing of this medical device can only be ensured if the processing method is first validated. The operator/sterile processing technician is responsible for this. The recommended chemistry was used for validation. Note If there is no final sterilization, then a virucidal disinfectant must be used. Note For up-to-date information about reprocessing and material compatibility, see also the Aesculap Extranet at https://extranet.bbraun.com The validated steam sterilization procedure was carried out in the Aesculap sterile container system.

General information Dried or affixed surgical residues can make cleaning more difficult or ineffective and lead to corrosion. Therefore the time interval between application and processing should not exceed 6 h; also, neither fixating pre-cleaning temperatures >45 °C nor fixating disinfecting agents (active ingredient: aldehydes/alcohols) should be used. Excessive measures of neutralizing agents or basic cleaners may result in a chemical attack and/or to fading and the laser marking becoming unreadable visually or by machine for stainless steel. Residues containing chlorine or chlorides e.g. in surgical residues, medicines, saline solutions and in the service water used for cleaning, disinfection and sterilization will cause corrosion damage (pitting, stress corrosion) and result in the destruction of stainless steel products. These must be removed by rinsing thoroughly with demineralized water and then drying. Additional drying, if necessary. Only process chemicals that have been tested and approved (e.g. VAH or FDA approval or CE mark) and which are compatible with the product’s materials according to the chemical manufacturers’ recommendations may be used for processing the product. All the chemical manufacturer's application specifications must be strictly observed. Failure to do so can result in the following problems: ■ Optical changes of materials, e.g. fading or discoloration of titanium or aluminum. For aluminum, the application/process solution only needs to be of pH >8 to cause visible surface changes. ■ Material damage such as corrosion, cracks, fracturing, premature aging or swelling. ► Do not use metal cleaning brushes or other abrasives that would damage the product surfaces and could cause corrosion. ► Further detailed advice on hygienically safe and material-/value-preserving reprocessing can be found at www.ak-i.org, link to Publications, Red Brochure – Proper maintenance of instruments.

Drinking water Fully desalinated water (demineralized, low microbiological contamination: drinking water quality at least) RT: Room temperature *Recommended: BBraun Stabimed ► Note the information on appropriate cleaning brushes and disposable syringes, see Validated cleaning and dis-

infection procedure. Phase I ► Clean the product in an ultrasonic cleaning bath (frequency 35 kHz) for at least 15 min. Ensure that all accessible surfaces are immersed and acoustic shadows are avoided. ► Clean the product with a suitable cleaning brush in the solution until all discernible residues have been removed from the surface. ► If applicable, brush through non-visible surfaces with an appropriate cleaning brush for at least 1 min. ► Mobilize non-rigid components, such as set screws, links, etc. during cleaning. ► Thoroughly rinse through these components with the cleaning disinfectant solution (at least five times), using a disposable syringe. Phase II ► Rinse/flush the product thoroughly (all accessible surfaces) under running water. ► Mobilize non-rigid components, such as set screws, joints, etc. during rinsing. ► Drain any remaining water fully.
