6.2 Introduction

6.2.1 These reprocessing instructions provide instructions for cleaning, disinfection, sterilization and packaging of manufacturer reusable products intended to be reprocessed in medical facilities.

6.2.2 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.

6.2.3 lt is recommended to use steam sterilization.

6.2.4 Remember that sterilization or high-level disinfection cannot be achieved unless the elements of the assembly are cleaned first.

6.2.5 lf you find that the reprocessing instructions from the manufacturer seem to be inadequate, please inform the manufacturer about those inadequacies.

6.2.6 We encourage adverse events related to device reprocessing be reported directly to the manufacturer.

6.3 Reprocessing -instructions for reusable products

6.3.1 The instructions are binding for the reprocessing of all reusable products (Here after called "product") of manufacturer. When necessary, additional product-specific instructions are included with the product to provide additional information.

lmportant: before use, carefully read the operating instructions of the manufacturer instrument and devices with which the product will be used.

6.3.2 Reusable product must be cleaned, disinfected and sterilized prior to first use. Reprocessing procedures have only limited implications to this device.

The limitation of the numbers of reprocessing procedures is therefore determined by the function / wear of the device.

From the processing side there is no maximum number of allowable reprocessing.

The device should no longer be reused in case of signs of material degradation.

In case of damage the product should be reprocessed before sending back to the manufacturer for repair.

6.4 Preparation-basic principles

6.4.1 lt 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.

6.4.2 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.

6.5 Preparation at the point of use

Disconnect product. Remove gross soiling of the scaler handpiece with cold water (<40'C) immediately after use. Don't use a fixating detergent or hot water (>40°C) as this can cause the fixation of residuals which may influence the result of the reprocessing process.

Store the scaler handpiece in humid surroundings.

6.6 Transportation

Safe storage and transportation to the reprocessing area to avoid any damage and contamination to the environment.

6.7 Preparation for decontamination

The scaler handpiece must be reprocessed in a disassembled state, as far as possible.

6.8 Pre-cleaning

Do a manual pre-cleaning, until the products are visually clean. Submerge the products in a cleaning solution and flush the lumens with a water jet pistol with cold tap water for at least 10 seconds. Clean the surfaces with a soft bristle brush.

6.9 Cleaning

Regarding cleaning/disinfection, rinsing and drying, it is to distinguish between manual and automated reprocessing methods. Preference is to be given to automated reprocessing methods, especially due to the better standardizing potential and industrial safety.

Automated Cleaning:

Use a washer-disinfector (WD) meeting the requirements of the lS0 15883 series.

Put the scaler handpiece into the machine on a tray. Connect the products with the WD by using suitable adapter and start the program:

4 min pre-washing with cold water (<40°C);

Emptying

5 min washing with a mild alkaline cleaner at 55°C;

Emptying

3 min neutralizing with warm water (>40°C);

Emptying

5 min intermediate rinsing with warm water (>40°C);

Emptying

The automated cleaning processes have been validated by using 0.5% nourisher MediClean forte (Dr. Weigert).

Acc. to EN IS0 17664 no manual reprocessing methods are required for these devices.

lf a manual reprocessing method must be used, please validate it prior to use.

6.10 Disinfection

Automated Thermal Disinfection in washer/disinfector under consideration of national requirements regarding A0 value (see EN 15883).

A disinfection cycle of 5 min disinfection at 93°C has been validated for the product to achieve an A0 value of 3000.

6.11 Drying

Automated Drying:

Drying of outside of products at 40°C, 5 min through drying cycle of washer/disinfector.

lf needed, additional manual drying can be performed through lint free towel. Insufflate

cavities of scaler handpiece by using sterile compressed air.

6.12 Functional testing, maintenance

Visual inspection for cleanliness of the scaler handpiece and reassembling if required. Functional testing according to instructions of use. lf necessary, perform reprocessing process again until scaler handpiece is visibly clean.

Before packaging and autoclaving, make sure that the scaler handpiece has been maintained according to manufacturer's instruction.

6.13 Packaging

Pack the scaler handpiece in an appropriate packaging material for sterilization.

The packaging material and system refer to EN ISO 11607.

6.14 Sterilization

Sterilization of scaler handpiece by applying a fractionated pre-vacuum steam sterilization process (according to EN 285/EN 13060/EN IS0 17665) under consideration of the respective country requirements.

Minimum requirements: 3 min at 134°C (in EU: 5 min at 134°C)

Maximum sterilization temperature: 138°C

Drying time:

For steam sterilization, we recommend a drying time of 15 to 40 minutes.

Choose a suitable drying time, depending on the autoclave and load.

Refer to the autoclave's instructions for use.

After sterilization:

a. Remove the scaler handpiece from the autoclave.

damaged.

   * Flash sterilization is not allowed on lumen 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 ISO 14937/ANSI AAMI ISO 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), considering the specific product geometry as part of the validation.

  • Maximum sterilization temperature 138°C.

Storage of sterilized products in a dry, clean and dust free environment with a relative humidity of 10% to 93%, an atmospheric pressure of 70KPa to 106KPa, and a temperature of-20°C to + 55°C; refer to label and instructions for use.

After sterilization, the product should be packaged in a medical sterilization bag or a clean sealing container and stored in a special storage cabinet.

The storage time should not exceed 7 days. lf it is exceeded, it should be reprocessed before use.

6.16 Service life

The scaler handpiece has been designed for many 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 devices. lf 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 (alkaline pH>9 or acid pH<5) can reduce the life span of devices. 

The manufacturer accepts no liability in such cases.

The scaler handpiece may not be exposed to temperatures above 138°C.

It is the duty of the user to ensure that the reprocessing processes including resources, materials and personnel can reach the required results. State of the art and often national law requiring these processes and included resources to be validated and maintained properly.
