Application

WARNING Risk of injury and/or malfunction! ► Prior to each use, inspect the product for loose, bent, broken, cracked, worn, or fractured components. ► Always carry out a function test prior to each use of the product.

®

Sterility

The product is delivered in an unsterile condition. ► Clean the new product after removing its transport packaging and prior to its initial sterilization.

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 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 "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

► Disassemble the product prior to cleaning, see Disassembly.

3.6

Disassembly

► Push in push button 4 at least halfway down. ► Rotate push button 4 by approx. 90° in any direction and release the push button.

The locking mechanism becomes detached. ► Remove push button 4 and spring 5.

Note Never unscrew lateral locking screw 6 on the rasp handle. This screw has been sealed with a special adhesive during the manufacturing process; it must not be removed.

3.7

Cleaning/Disinfection

3.7.1

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! ► Following the manufacturer's instructions, use cleaning and disinfecting agents that are approved for, e.g., aluminum, plastics and high-grade steel. ► Observe specifications regarding concentration, temperature and exposure time. ► Do not exceed the maximum allowable disinfection temperature of 95 °C.
