1Neutral pH detergent: Adjust concentration according to the detergent manufacturer’s directions regarding water quality and the extent of instrument soiling.
2Minimum exposure conditions for thermal disinfection.
3As cleaning frequently involves mixed instrument loads, the efficacy of drying will vary based on the equipment and the nature and volume of the load being processed. Therefore, the drying parameters must be determined by observation.

  1. Following processing, carefully inspect the instrument for cleanliness, any evidence of damage, and proper operation. If visible soil remains on the instrument following processing, it should be reprocessed or manually cleaned.

Manual Cleaning

  1. Disassemble the instrument as applicable and inspect the instrument for damage or corrosion.
  2. Pre-rinse the instrument by holding it under cold running water for at least 30 seconds, rotating the instrument to expose all surfaces and cavities to flowing water. Additional rinsing may be necessary depending on the size and extent of soiling of the instrument.
  3. Place the instrument into a suitable clean basin filled with fresh neutral pH cleaning solution prepared according to the directions of the solution manufacturer. Use only cleaning solutions that are labeled for use with medical devices or surgical instruments. Ensure that the instrument is fully immersed in the cleaning solution. The following conditions were validated using a neutral pH detergent (Steris ProKlenz NpH) and a severe organic soil challenge (Biomedical Instrumentation and Technology 2007;41(4):324-331).
  4. Using a soft cleaning brush gently scrub all surfaces of the instrument while keeping the instrument submerged in the cleaning solution for at least 5 minutes. Clean the instrument until all visible soil has been removed.
  5. Rinse the instrument by holding it under cold running water for at least 30 seconds, rotating the instrument to expose all surfaces and cavities to flowing water. Additional rinsing may be necessary depending on the size of the instrument and the amount of soil.
  6. Place the instrument in an ultrasonic bath filled with fresh neutral pH cleaning solution and sonicate for 5 minutes. Use only cleaning solutions that are labeled for use with medical devices or surgical instruments. Ensure that the instrument is fully immersed in the cleaning solution. Do not overload the ultrasonic bath or allow instruments to contact one another during cleaning. Do not process dissimilar metals in the same ultrasonic cleaning cycle.

WARNING: Do not process powered instruments in an ultrasonic cleaner.

  1. The cleaning solution should be changed before it becomes visibly soiled. The ultrasonic bath should be drained and cleaned each day it is in use or more frequently if visible soiling is evident. Follow the instructions of the manufacturer for the cleaning and draining of the ultrasonic bath.
  2. Repeat steps 4-6 as necessary if visible soil remains on the instrument.
  3. Rinse the instrument by holding it under warm (27º to 44ºC/80º to 111ºF) running water for at least 30 seconds, rotating the instrument to expose all surfaces and cavities to flowing water. Additional rinsing may be necessary depending on the size of the instrument.
  4. If the instrument has lumens, the lumens should be flushed using a syringe filled with 50cc of warm distilled or deionized water using a stopcock as follows:
    1. Place syringe tip into a beaker of warm (30º to 40ºC/86º to 104ºF) distilled or deionized water and fill to the 50cc mark.
    2. Connect the end of the syringe to the center stopcock fitting.
    3. Rotate the stopcock lever to the male luer fitting (irrigation) or to the female luer fitting (aspiration) to allow fluid to flow to the appropriate luer fitting.
    4. Connect the stopcock to the appropriate luer connector on the instrument.
    5. Push on the syringe plunger to force fluid through the lumen into another beaker for proper disposal. Do not draw flushing fluid back through the lumen. Disconnect the syringe. Disconnect the syringe/stopcock from the instrument.
    6. Repeat steps a-e at least three times, for each lumen.
    7. Fill the syringe with 50cc of air, reattach the stopcock, and push on the plunger to force air through each lumen. Disconnect the syringe/stopcock from the instrument.
      NOTE: The CX7120 Universal Maintenance Kit contains a syringe and stopcock suitable for cleaning instrument lumens
  5. Immerse the instrument in a clean basin containing fresh deionized or distilled water and soak the instrument for at least three minutes.
  6. Immerse the instrument in a second clean basin containing fresh deionized or distilled water and soak for at least three minutes.
  7. Perform a final rinse of the instrument with sterile distilled or deionized water for at least 30 seconds, rotating the instrument to expose all surfaces and cavities to flowing water.

Disinfection
Due to the potential for residual chemicals to remain on the instrument and cause an adverse reaction, Bausch + Lomb does not recommend the use of liquid chemical disinfectants or sterilants with instruments. See Automated Cleaning and Thermal Disinfection above for procedures for thermal disinfection of instruments in an automated washer/disinfector.

Drying
Carefully dry the instrument with a lint-free surgical wipe or blow the instrument dry with micro-filtered forced air.

Maintenance, Inspection and Testing
Following cleaning, inspect the instrument to ensure that all visible soil has been removed and that the instrument operates as intended.

Packaging
Package the instrument in a suitable sterilization pouch, Central Supply Room (CSR) wrap or tray.

Sterilization
Unless otherwise indicated in the Directions for Use provided with the specific instrument, instruments and instrument trays may be sterilized by the following moist heat (steam) sterilization methods:

  • Pre-vacuum High Temperature Autoclave: 270ºF (132ºC) for 4 minutes; wrapped.
  • Standard Gravity Autoclave: 250ºF (121ºC) for 30 minutes; wrapped.
  • High Speed (Flash) Autoclave: 270ºF (132ºC) for 10 minutes; unwrapped, but covered.

WARNING: Instruments processed in a wrapped instrument tray should be placed within the tray in a manner that allows steam to contact all surfaces of the instrument. Do not pile instruments on top of each other as this may block steam penetration and condensate drainage. Do not overload the tray. Heavily loaded instrument trays should be processed by high temperature pre-vacuum steam sterilization.

WARNING: Flash (Immediate Use Steam) sterilization processing should be reserved for emergency reprocessing only and should not be employed for routine processing of the instrument. Instruments processed by flash sterilization should be processed individually or in trays specifically designed for use with flash sterilization. Flash sterilized items should be used immediately, and not stored for later use. See ANSI/AAMI ST79, current revision, and your institution’s policies for restrictions regarding the use of flash sterilization.

WARNING: Single-use instruments should not be reprocessed.

The instrument and/or instrument tray should be processed through a complete sterilization drying cycle as residual moisture from autoclaves can promote staining, discoloration, and rust.

WARNING: Although instruments have been validated to Type 121ºC Gravity, 30 Minute Full Cycle, the user must ensure that if using a sterilization tray, that instruments are not overloaded which could result in uneven dry times.

WARNING: Rigid Instrument Tip Protectors should only be sterilized five (5) times or less. Silicone Tubing Tip Protectors should never be sterilized

WARNING: Silicone Bulbs are to be sterilized under pre-vacuum conditions only.

Storage
Following sterilization processing, packaged instruments may be stored in a clean area free of temperature and humidity extremes in accordance with your institution’s policies.
