INTRODUCTION

1. These reprocessing instructions provide instructions for cleaning, disinfection, sterilization and packaging of manufacturer reusable products intended to be reprocessed in medical facilities.
2. The goal of reprocessing reusable products is to reduce bioburden and to achieve sterility of those products in order to eliminate the risk of product reuse related infection. Decisions regarding cleaning, disinfecting or sterilizing manufacturer’s medical and dental instruments are based on the potential risk of infection associated with their use.
3. It is recommended to use steam sterilization.
4. Remember that sterilization or high-level disinfection cannot be achieved unless the elements of the assembly are cleaned first.
5. If you find that the reprocessing instructions from the manufacturer seem to be inadequate, please inform manufacturer about those inadequacies.
6. We encourage you to report adverse events related to device reprocessing. Report such events directly to manufacturer.

REPROCESSING – INSTRUCTIONS FOR REUSABLE PRODUCTS
The instructions are binding for the reprocessing of all reusable products (Here after called “products”) of manufacturer. When necessary, additional product-specific instructions are included with the product to provide additional information.Important: Before use, carefully read the operating instructions of the manufacturer instrument and devices with which the product will be used. Reusable products must be cleaned and sterilized prior to first use. They must be replaced after the number of operations specified by the manufacturer. Disposable products (single use) cannot be reused.

PREPARATION – Basic principles

It is only possible to carry out effective sterilization after the completion of effective cleaning and disinfection. Please ensure that, as part of your responsibility for the sterility of products during use, only sufficiently validated equipment and product-specific procedures are used for cleaning/disinfection and sterilization, and that the validated parameters are adhered to during every cycle.

Please also observe the applicable legal requirements in your country as well as the hygiene regulations of the hospital or clinic. This applies especially with regard to the additional requirements for the inactivation of prions.

POST-OPERATIVE TREATMENT
The post-operative treatment must be carried out immediately, no later than 30 minutes after the completion of the operation. Additional information, while necessary, is provided in the respective product-specific usage instructions.

Steps:

1. Rinse away any surface soiling on the product with distilled deionized water or with a cleaning agent.
2. Rinse through all lumina (E.g. irrigation and aspiration connection) at least 3 times in the normal direction of flow (no back rinsing) using a disposable syringe (min. volume 50 ml) filled with distilled/ deionized water applied to the back nozzle.
3. An aldehyde-free cleaning and disinfection solution that is compatible with the products may also be used as an alternative rinsing solution. In such cases, it is necessary to rinse thoroughly afterwards at least 3 times with distilled, or deionized water.

CLEANING/DISINFECTION:

MECHANICAL REPROCESSING
Disinfection must be performed no later than 2 hours after the cleaning phase. A machine cleaning and disinfection method should always be used for cleaning / disinfection because of the increased effectiveness of this method.

MECHANICAL CLEANING AND DISINFECTION

1. Thermal disinfection should be used if this function is available on your disinfector. Use if possible a disinfecting cycle compliant with the standard EN ISO 15883.
2. Note that there is a risk of disinfectant residue on products when using chemical disinfectants.
3. Ensure the following criteria are met when selecting a disinfector system:
   • Disinfector is proven effective through testing (E.g. FDA approved or CE marked / EN ISO 15883 compliant).
   • Disinfector has suitable baskets to hold small fragile products and has rinsing connections for the attachment to product lumina.
   • The cleaning program is suitable for products to be processed and the rinsing cycle is sufficient.
   • Only low microbe count (<10 cfu/ml) distilled or deionized water is used for all rinsing steps. (E.g. Aqua purificata, as per the specifications of Pharm. Eur. or USP).
   • Air used for drying is HEPA filtered.
   • Disinfector is serviced and checked on a regular basis.
4. Ensure the following criteria are met when selecting a cleaning and disinfection agent:
   • Chemicals are compatible with products.
   • With non-thermal disinfection, a suitable disinfectant with tested effectiveness (E.g. FDA approved or CE marked), that is compatible with the cleaning agent, must be used. Concentrations and contact times specified by the manufacturer of the cleaning and disinfection agent must be followed. Only freshly prepared solutions may be used.
5. Steps for mechanical cleaning and disinfection with a disinfector
6. Load the WD with the instruments on the tray and start the WD with a full load. Run the cleaning cycle of the “surgical instrument” programme in accordance with the manufacturer’s instructions.
   Instrument cleaning program:

  * pre-wash (5 minutes, ambient temperature water)
  * cleaning (5 minutes, 0.5% neutral pH detergent, 40℃)
  * rinse I (1 minute, ambient temperature water)
  * rinse II (1 minute,ambient temperature water)
  * disinfection (2.5 minutes, pure water 93℃)
2. Immediately after the cleaning cycle, interrupt the program and unload the samples.
3. After cleaning in the WD, examine the instruments visually.
4. Carefully place the products in the disinfection basket. Fastening of the products is only permissible if they are freely moveable in the fixture. The products are not permitted to make contact with one another.
5. Using a suitable rinsing adaptor, connect the product lumina to the rinsing connections of the disinfector.
6. Start the program.
7. Remove the products from the disinfector and start the inspection (see section Inspection and maintenance) after the program ends.
8. Wrap the products directly following disinfection and drying (see section Packaging and sterilization). If necessary, repeat drying of the product in a clean place.

INSPECTION AND MAINTENANCE
If stains are still visible on the product after cleaning/disinfection, the Nentire cleaning/disinfection procedure must be repeated. Products with visible damage, chip/flake loss, corrosion or bent out of shape must be disposed of (no further use is permissible).

PACKAGING AND STERILIZATION

• Compliant with EN ISO 11607,

• Resistant to 138°C, with adequate steam permeability,

• Maintained on a regular basis.
  If double, single-use sterilization packaging (double bag) is to be used, this must also comply with EN ISO 11607 and be suitable for steam sterilization (temperature resistant to 138°C with adequate steam permeability). Use only the following listed steam sterilization procedures for sterilization; other sterilization procedures are not permissible:

• Fractional pre-vacuum procedure (steam sterilization with repetitive pre-vacuum.)

• Steam sterilizer in accordance with EN 13060 or EN 285 validated in compliance with EN IS0 17665,

• Maximum sterilization temperature 138°C,

• Sterilization time at least 3 min. at 134°C (fractional pre-vacuum procedure).

• Sterilization at 134°C for a maximum of 20 minutes is permissible.

The hot-air sterilization and radio-sterilization procedure may not be used (as it causes the destruction of products). The manufacturer assumes no responsibility for the use of other sterilization procedures (E.g. ethylene oxide, formaldehyde and low temperature plasma sterilization). In such cases, please observe the respective valid standards (EN IS0 14937/ANSI AAMl IS0 14937 or the procedure-specific standard) and verify the suitability and effectiveness in principle of the procedure (if necessary, including investigations on sterilizing agent residue), taking into account the specific product geometry as part of the validation.

SERVICE LIFE
The products have been designed for a large number of sterilization cycles. The materials used in their manufacture were selected accordingly. However with every renewed preparation for use, thermal and chemical stresses will result in aging of the products. If the number of permissible re-sterilization cycles is restricted, this will be pointed out in the product specific instructions. The use of ultrasound baths and strong cleaning and disinfection fluids (alkaling pH > 9 or acid pH< 5) can reduce the life span of products. The manufacturer accepts no liability in such cases. The products may not be exposed to temperatures above 138°C.
Note : We reserve the rights to change the design of the equipment, the technique, fittings, the instruction manual and the content of the original packing list at any time without notice. If there are some differences between blueprint and real equipment, take the real equipment as the norm.
