3. 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 oper-
ator/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 pre-cleaning temper-
atures >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. Fail-
ure 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 applica-
tion/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 Preparing for cleaning
► Unscrew attachment from handle prior to cleaning.
3.6 Cleaning/Disinfection
3.6.1 Product-specific safety information on the reprocessing method
Damage to or destruction of the product due to inappropriate cleaning/disinfecting agents and/or excessive temper-
atures!
► Following the manufacturer's instructions, use cleaning and disinfecting agents
– that are approved for high-grade steel,
– that do not attack softeners (e.g., in silicone).
► Observe specifications regarding concentration, temperature and exposure time.
► Do not exceed the maximum allowable disinfection temperature of 95 °C.
► Use suitable cleaning/disinfecting agents if the product is disposed of in a wet condition. To prevent foaming and
degradation of the efficacy of the process chemicals: prior to mechanical cleaning and disinfection, rinse the
product thoroughly with running water
