Instrument care 1. Limitations on reprocessing Repeated processing has not been shown to have an effect on these instruments.
2. Cleaning and sterilization instructions The surgical instruments are provided non-sterile and must be cleaned and sterilized before use.
3. From point of use • • •
Wherever possible, do not allow blood, debris or bodily fluids to dry on the instruments. Reprocess immediately after use for best results and to prolong the life of the instruments. If they cannot be reprocessed immediately, use a damp cloth over the instruments to help prevent the soil from drying.
4. Preparation before automated cleaning • •
•
Rinse with cold running tap water until all visible soil is removed. Pre-clean the instruments by fully immersing the device and using a soft bristled brush with the enzymatic detergent to scrub the device. Make sure to brush all crevices, grooves and slots, taking care to ensure that the measuring rod is not damaged. Rinse the instruments until no visible detergent is present.
