infecting solution.

General safety instructions

Note Adhere to national statutory regulations, national and international standards and directives, and local, clinical hygiene instructions for sterile processing.

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

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.

6.3

Preparations at the place of use

► 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.

6.4

Drinking water Fully desalinated water (demineralized, low microbiological contamination: drinking water quality at least) Room temperature

Preparation before cleaning

Phase I ► Clean the product under running faucet water, using a suitable cleaning brush until all visible residues have been removed from the surfaces. ► Mobilize non-rigid components, such as set screws, links, etc. during cleaning. Phase II ► Dry the product in the drying phase with suitable equipment (e.g. cloth, compressed air), see Validated cleaning and disinfection procedure. Phase III ► Wipe all surfaces of the product with a single-use disinfectant wipe. Phase IV ► After the specified exposure time (at least 1 min), rinse the disinfected surfaces under running FD water. ► Drain any remaining water fully. Phase V ► Dry the product in the drying phase with suitable equipment (e.g. cloth, compressed air), see Validated cleaning and disinfection procedure.

6.7

Inspection, maintenance and checks

► Allow the product to cool down to room temperature. ► Inspect the product after each cleaning and disinfecting cycle to be sure it is: clean, functional, and undamaged. ► After every cleaning and disinfecting cycle, lubricate the product at lubrication point 10 with a drop of oil from

STERILIT Power Systems drip lubricator GA059. ► Check the product for any damage, abnormal running noise, overheating or excessive vibration. ► Inspect tools for broken, damaged or blunt edges. ► Set aside the product if it is damaged.

► Carry out non-fixating/NaCl-free pre-cleaning immediately after use.

6.8 6.5

Cleaning/disinfection

Packaging

► Always observe the instructions for use of packaging and storage devices. ► Pack trays appropriately for the sterilization process (e.g. in Aesculap sterile containers). ► Ensure that the packaging will prevent a recontamination of the product.

Product-specific safety instructions for the reprocessing procedure Damage to, or destruction of the product caused by mechanical cleaning/disinfection! ► Only clean and disinfect the product manually. CAUTION

6.9

Steam sterilization

► Prior to sterilization, remove any tools and adapters and uncouple the handpiece from the motor unit. ► 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

Damage to the product due to inappropriate cleaning/disinfecting agents! ► Only use cleaning/disinfecting agents approved for surface cleaning. Follow the manufacturer’s instructions for the respective cleaning/disinfecting agent. CAUTION

CAUTION

Damage to the product due to inappropriate cleaning/disinfecting agents and/or excessive temperatures! ► Use cleaning and disinfecting agents according to the manufacturer’s instructions which – be approved for plastic material and high-grade steel, – do not attack softeners (e.g. in silicone). ► Observe specifications regarding concentration, temperature and exposure time.

► Do not clean motors/handpieces by ultrasonic treatment and do not immerse them in any liquids. To avoid the

risk of corrosion/malfunctioning, allow any fluid that has entered the product to drain out immediately.

■ When cleaning instruments with movable

Chapter Manual cleaning/disinfecting and subsection:

hinges, ensure that these are in an open position and, if applicable, move the joint while cleaning.

■ Drying phase: Use a lint-free cloth or compressed air for medical purposes

■ Ensure that the product is positioned in such a way that water will not enter the product e.g. through coupling interfaces. (Immediately remove any fluid that entered the product inadvertently.)

■ Chapter Manual cleaning and wipe disinfecting

– Disassemble the instrument – Steam sterilization through fractionated 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 ► When sterilizing several instruments at the same time in a steam sterilizer, ensure that the maximum load capacity of the steam sterilizer specified by the manufacturer is not exceeded.

6.10 Storage ► Store sterile products in germ-proof packaging, protected from dust, in a dry, dark, temperature-controlled area.
