Storage, Handling and Disposal

Storage, Handling and Disposal • Reusable devices that will be stored between cleaning and sterilization should be dry to prevent microbial contamination that could result from wet devices. Containment devices can be stacked for storage. Store in a dry dust-free place. • Storage of devices after cleaning and sterilization should be in designated, limited access areas that are well ventilated and provide protection from dust, moisture, insects, vermin and temperature and humidity extremes.

• Be sure to arrange the items so that the water can easily flow out of cannulations, blind holes, and cavities. • For instruments with long or narrow lumens, standard processing should be used only if the disinfectant can flow easily through the lumens and safe rinsing is guaranteed. • The cases/trays used for cleaning must always be loaded correctly to ensure proper cleaning.

• Storage is event related and not time related.

• After cleaning, check instruments for cleanliness (visible dirt). This especially applies to cannulated instruments or those with blind holes and crevices.

• ASCENSION◊ Orthopedics does not recommend stacking of wrapped containment devices or rigid containers.

• To ensure proper instrument functioning, verify that all movable parts have been thoroughly cleaned.

• Reusable devices that have been inspected and have reached the end of their lifetime should be sterilized, if possible, and disposed according to institutional procedures. Single use devices should be disposed of according to institutional procedures, after use. Devices that are unable to be sterilized before disposal should be disposed properly as a potential biohazard.

• Pay special attention to slots, ratchets, joints and box locks, narrow lumens, blind holes, and other areas that are hard to access. • Deionized or distilled water should be used for the final rinse. Note: following cleaning, the instruments must be macroscopically clean, i.e. free from visible dirt or deposits. All movable parts, working tips and blades should be inspected with particular care. After cleaning, visually inspect devices under normal lighting for the removal of visible debris. Repeat cleaning if not visibly clean and reinspect the device.

• No hazardous substances are contained or come in contact with the device, components, or raw materials. Therefore, the risk of environmental impact upon proper disposal of the subject devices is considered negligible. The subject devices have not been evaluated for long term environmental impact.

Preparation/General Guidance For Cleaning

The following steps should be completed in sequence. Please note that all instructions provided are validated. Depending upon the detergent selection, minimum processing times and temperature settings may need to be adjusted for optimal processing:

Verify that all instruments required for use are present in the case. It is not recommended to use chloride containing cleaning solutions since its use has been linked to corrosion of metallic instruments, especially stainless steel. Please also note the following: • Disinfect and clean devices immediately after use in order to avoid device encrustations.

1. Prepare a neutral pH enzymatic detergent as per the manufacturer’s recommendation (e.g. Enzol® prepared at 1 oz. per gallon of lukewarm deionized water). 2. Disassemble instruments to lowest level.

• Use a suitably sized non-metallic bristle brush for cleaning lumens, cannulations, blind holes, and cavities, making sure that every part of the inner surface can be properly accessed.

3. Rinse devices under lukewarm running water to remove all gross soil. Use a soft bristled brush to aid in the brushing. Agitate the instruments under the running water. Agitation includes actuating all movable parts such as opening and closing hinges and moving the instruments around under the running water. Use a clean soft bristled brush and/or pipe cleaner to brush and aid in the rinse for the exterior and interior of instruments. Use a syringe to flush any lumens.

• Clean jointed instruments in closed as well as open positions.

4. Fully immerse each device in the prepared detergent and allow it to soak for a minimum of two minutes.

• Solutions used for cleaning must always be prepared in accordance with the manufacturer’s instructions. • Never use metal brushes or metal sponges for manual cleaning.

• Disassemble instruments as far as possible before cleaning.
