ISO 17664 compliance The process for cleaning, disinfection and sterilization of the applicable parts of the anesthesia system has been validated and found to be in compliance with ISO 17664. These instructions have been validated by the manufacturer of the medical device as being capable of preparing a medical device for reuse. It remains the responsibility of the processor to make sure that the reprocessing is actually performed using equipment, materials, and personnel in the reprocessing facility to achieve the desired result. This requires validation and routine monitoring of the process. Any deviation by the processor from the instructions provided should be properly evaluated for effectiveness and potential adverse consequences. The manufacturer recommends the use of filter(s) that protect both the inspiratory and expiratory ports to reduce the risk of crosscontamination. See "Breathing system removal", "Breathing system disassembly", and "Sterilization".

Cleaning information Clean and sterilize the breathing system prior to first use after installation. See "Compatible chemical agents" for a list of the approved cleaning agents. Immediately clean potentially infectious material, for example blood or secretions, from the system by wiping the contaminated area using a disposable cloth and an approved cleaning and disinfectant agent. Parts marked 134°C are autoclavable. All parts in the breathing system, except the circuit O2 cell and flow sensors, can be washed in an automated washer using mild detergent. Only surface clean the circuit O2 cell. Do not autoclave the circuit O2 cell. Do not wash the circuit O2 cell or flow sensors in an automated washer. A Cleaning Cassette kit is available to assist in the cleaning of the breathing system when using an automatic washer. Always perform a preoperative test after reassembly and prior to use. The anesthesia system User’s Reference manual contains a preoperative checkout list and preoperative test instructions. Inspect and replace any damaged parts in the breathing system, if the test failed.

WARNING

2076865-001

Obey applicable safety precautions:

3

Read and understand the material safety data sheet for each cleaning agent.

•

Read and understand the manual for all sterilization equipment to be used.

•

Follow facility guidelines for use of personal protective equipment during cleaning and sterilization procedures.

•

A damaged O2 cell can leak and cause burns. Do not breathe the fumes.

•

Failure to properly install and use bacterial or viral filters in a way that protects the inspiratory and expiratory ports will result in additional required cleaning and sterilization procedures. If bacterial or viral filters are not used, perform the cleaning and sterilization procedures specified in this guide before each patient to avoid crosscontamination between patients.

•

The breathing system should be reprocessed regularly. Contamination is possible. Follow facility guidelines to determine requirements for reprocessing that addresses potential contamination, including an adequate minimum interval between reprocessing which addresses all potential sources of contamination.

•

To help prevent fires: •

All covers used on the system must be made from antistatic (conductive) materials. Static electricity can cause fires.

•

Desiccated (dehydrated) absorbent material may produce dangerous chemical reactions when exposed to inhalation anesthetics. Adequate precautions should be taken to ensure that absorbent does not dry out. Turn off all gases when finished using the system.

•

Obey infection control and safety procedures. Used equipment may contain blood and body fluids.

•

Moveable parts and removable components may present a pinch or a crush hazard. Use care when moving or replacing system parts and components.

CAUTION

Refer to the manufacturer’s data if you have questions about a cleaning agent. Follow facility procedures for cleaning areas of the machine not specified in this section. Do not wipe the surfaces or clean the system using organic, halogenated, or petroleum-based solvents, anesthetic agents, glass cleaners, acetone, or other harsh cleaning agents. Doing so can damage the labels or the system. Do not use abrasive cleaning agents (such as steel wool, silver polish or cleaner). Keep all liquids away from electronic parts. Do not permit liquid to go into the equipment housings. Do not soak parts for more than 15 minutes. Swelling or accelerated aging can occur. Only autoclave parts marked 134°C. Do not exceed 134°C. Cleaning solutions must have a pH of 7.0 to 10.5. Organic, halogenated or petroleum-based solvents, anesthetic agents, glass cleaners, acetone, and other harsh cleaning agents should not be used.

5

Cleaning and maintenance schedule Refer to the anesthesia system’s User’s Reference manual for complete maintenance instructions regarding the anesthesia system. Minimum Frequency During cleaning and setup As necessary

•

Inspect the parts for damage. Replace, repair or reprocess as necessary.

•

Wipe the anesthesia system’s external surfaces. Empty the absorber canister body and replace the absorbent in the canister. Empty the overflow trap on the optional suction regulator. Replace the circuit O2 cell. (Under typical use the cell meets specifications for 2 years). Replace the autoclavable flow sensors. (Under typical use the sensor meets specifications for a minimum of 1 year.)

Surface cleaning and disinfection External parts and exposed surfaces that are touched while using this device must be cleaned and disinfected when soiled. Follow healthcare facility guidelines for cleaning and disinfecting intervals.

CAUTION

Do not use a dripping cloth on surfaces. Make sure there is no liquid pooling on surfaces or entering the device. Damage to the device could occur. Replace the cloth as needed.

WARNING

Make sure that cleaning and disinfecting solutions do not penetrate the inside of the device. Electrical shock could occur.

Cleaning instructions Cleaning solution Bleach solution (1:10 diluted 5.25% sodium hypochlorite solution) 70% Isopropyl Alcohol

•

• •

Thoroughly clean the surfaces of the device with a lint-free cloth pre-soaked with the cleaning solution. Wring excess liquid from the cloth before wiping the surfaces. Clean the surfaces until soil and organic matter is visibly removed. Pay attention to connected surfaces, recessed areas, ridges, and other difficult to clean areas of the device. Inspect the device to confirm the complete removal of soil from surfaces. If soil is still present, clean the device again.

Disinfecting instructions Disinfecting solution

If the surface dries before the disinfection time duration, wipe the surface again with another new lint-free cloth pre-soaked with disinfecting solution.

2076865-001

Compatible chemical agents The compatible chemical agents listed have been tested and found not to cause harm to the anesthesia system parts. Read the material safety data sheet (MSDS) for each chemical agent. Use of these chemicals will not damage the components when used as suggested, but efficacy of cleaning or disinfection has not been demonstrated in all cases. The compatible chemical agents listed may not be available or approved for use in all countries. Follow hospital guidelines for cleaning and chemical agent use.

CAUTION

Important Note

Cleaning solutions not shown in the chemical agents list must have a pH of 7.0 to 10.5. Organic, halogenated or petroleum-based solvents, anesthetic agents, glass cleaners, acetone, and other harsh chemical agents are not recommended. Use of any chemical agents other than listed in this table may degrade system performance. The use of chlorinated cleaning and disinfecting agents on metal parts can over time lead to small cosmetic surface oxidation spots on the metal parts.

Breathing system cleaning Use the recommended method to clean the breathing system parts. See "Compatible chemical agents" for a list of cleaning agents that have been tested and found to cause no harm to breathing system parts.

Cleaning cassette kit The cleaning cassette kit is intended to enhance the cleaning of the breathing system. Using the cleaning cassette and automated washer plugs provides effective particulate removal using optimal water flow management through the breathing system parts. Disassemble the breathing system to the level shown in the "Breathing system removal" and "Disassemble the breathing system" procedures. Plug the unused washer ports before starting the automatic washer, using the cleaning cassette. After washing, remove the parts from the washer and drain any water. Allow parts to cool and dry completely before reassembling the breathing system.
