Validated processing procedure

3.1

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 processing of products. Note Mechanical processing 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. Note Sterilization should always be favored over disinfection under all circumstances. Only if final sterilization is not possible should disinfection with a virucidal agent be preferred. Note Up-to-date information about processing and material compatibility can be found on the B. Braun eIFU site at eifu.bbraun.com The validated steam sterilization procedure was carried out in the AESCULAP sterile container system.

3.2

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 precleaning 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.a-k-i.org, link to "AKI-Brochures", "Red brochure".

3.3

3.7.1

Product-specific safety information on the processing method

Danger to the patient! The product must not be manually processed. ► Process the product only by manually pre-cleaning followed by cleaning in a mechanical washer/disinfector. Risk to patient due to cross contamination! ► Do not use contaminated products that have already been used in the CNS in other areas unless they have been cleaned with an alkaline cleaner (pH ≈ 11). Damage to or destruction of the product due to inappropriate cleaning/disinfecting agents and/or excessive temperatures! ► Use cleaning and disinfecting agents according to the manufacturer's instructions. ► Observe specifications regarding concentration, temperature and exposure time. ► Do not exceed the maximum allowable disinfection temperature of 95 °C. ► If the microsurgical products can be securely fixed in machines or storage devices in such a way that they will be cleaned thoroughly, clean and disinfect them mechanically.

3.7.2
