Processing information Processing information

Process the breathing system prior to the first use after installation. 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 chemical agent. See "Compatible chemical agents" for a list of the approved cleaning agents.

WARNING

CAUTION

•

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

•

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

•

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

To help prevent damage: • • • • • • • •

2094883-001

Refer to the manufacturer's data for specific cleaning agent information. Follow facility procedures for cleaning areas of the machine not specified in this manual. 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 30 minutes unless indicated. Swelling or accelerated aging can occur. Parts marked 134°C are autoclavable. Do not exceed 134°C. Cleaning solutions must have a pH of 7.0 to 10.5. Do not use organic, halogenated or petroleum-based solvents, anesthetic agents, glass cleaners, acetone, and other harsh cleaning agents.

Cleaning and Sterilization

Intended use Use this manual along with the anesthesia system User’s Reference manual. Always perform a preoperative checkout before using the anesthesia machine after reassembly. The anesthesia system User’s Reference manual contains a preoperative checkout list and preoperative test instructions.

ISO 17664 compliance The process for sterilization of the breathing 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 processing is actually performed using equipment, materials, and personnel in the processing facility to 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. Contamination from environmental exposure and crosscontamination from patient exposure are possible. It is recommended that filter(s) that protect both the inspiratory and expiratory ports are used to reduce the risk of contamination.

Processing overview This User’s Reference manual provides information and instructions for the Advanced Breathing System assembly and disassembly, manual cleaning, automated washing, and sterilization. For reliable operation of the Advanced Breathing System, clean and sterilize the system according to the information in this manual. An overview of the typical processing activity is described below. Not all components may follow these specific steps. Detailed instructions for each step are provided within this manual. Important

All parts must use the manual cleaning/soaking process or the automated washer process (if appropriate) before sterilization. 1. 2. 3.

Remove the absorber canister and breathing system. Disassemble the breathing system. Manually clean parts that are not allowed in the automated washer or if washer is not available, manually clean all parts. 4. Visually inspect parts for damage, deformations, cracking, and cleanliness. Replace parts as necessary. 5. Attach the cleaning accessories to the breathing system parts. Wash the breathing system using the cleaning accessories in the automated washer. 6. Remove the parts from the automated washer and remove the cleaning accessories from the breathing system parts. 7. Visually inspect parts for damage, deformations, cracking, and cleanliness. Replace parts as necessary. 8. Wrap parts prior to sterilization. 9. Perform sterilization (check parts for 134°C). 10. Allow parts to completely dry and cool. 11. Visually inspect parts for damage, deformations, cracking, and cleanliness before reassembly. Replace parts as necessary. 12. Reassemble the bellows and breathing system parts, install the breathing system, and the absorber canister.
