Validated reprocessing 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 reprocessing of products. 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. 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 B. Braun eIFU 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

Reusable products

Influences of the reprocessing which lead to damage to the product are not known. A careful visual and functional inspection before the next use is the best opportunity to recognize a product that is no longer functional, see Inspection.

3.4

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.

3.5

Cleaning/Disinfection

3.5.1

Product-specific safety information on the reprocessing method

Damage to or destruction of the product due to inappropriate cleaning/disinfecting agents and/or excessive temperatures! ► Use cleaning and disinfecting agents approved for high-grade steel and plastics according to manufacturer’s instructions. ► Observe specifications regarding concentration, temperature and exposure time. ► Do not exceed the maximum allowable disinfection temperature of 95 °C. ► If there are bone, tissue or ancillary material (e.g. plaster, bone cement) residues: pre-clean the product manually (using a cleaning brush).

Phase I ► Fully immerse the product in the cleaning/disinfectant for at least 15 min. Ensure that all accessible surfaces are moistened. ► 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. Phase III ► Fully immerse the product in the disinfectant solution. ► Mobilize non-rigid components, such as set screws, joints, etc. during rinsing. ► Rinse lumens at least 5 times at the beginning of the exposure time using an appropriate disposable syringe. Ensure that all accessible surfaces are moistened.

3.10 Steam sterilization Note To avoid breakage due to stress crack corrosion, sterilize the instruments with the lock fully open or locked no further than on the first ratchet tooth. ► Check to ensure that the sterilizing agent will come into contact with all external and internal surfaces (e.g., by opening any valves and faucets). ► Validated sterilization process – Steam sterilization using fractional vacuum process – Steam sterilizer according to DIN EN 285 and validated according to DIN EN ISO 17665 – Sterilization using fractionated vacuum process at 134 °C/holding time 5 min ► If several devices are sterilized at the same time in the same steam sterilizer: Ensure that the maximum permitted load according to the manufacturers’ specifications is not exceeded.
