A7™ Operating Instructions 046-004667-00 xiii
Warnings Introduction
WARNING: Usage of accessories found with damaged packaging may cause
biocontamination or failure. The operator should check accessory
packaging integrity before use.
WARNING: Before using the A7 System (after cleaning or disinfecting), power up
the system and follow the on-screen prompts to perform the leak test
and the compliance test. See section 4.5 (page 4-8) "Leak and
Compliance Tests".
WARNING: Improperly cleaned materials may result in biocontamination. Use a
cleaning and disinfection schedule that conforms to your institution's
disinfection and risk-management policies.
• Refer to the material safety data as applicable.
• Refer to the operation and maintenance manuals of all disinfection
equipment.
The user should follow the recommended disinfection routine for this
machine and any reusable accessories.
WARNING: If the A7 is damaged in any way that compromises the safety of the
patient or user, discontinue use and attach a visible tag that marks the
A7 as unusable. Call Mindray Technical Support.
WARNING: Oxygen, when present in high concentrations, can significantly
increase the chance of fire or an explosion. Oil and grease may
spontaneously ignite and as such should not be used where oxygen
enrichment may occur.
WARNING: Use of lubricants not recommended by Mindray may increase the
danger of fire or explosion. Use lubricants approved by Mindray.
WARNING: Low-pressure regulators and flow-meters are susceptible to high
pressure, and may burst if improperly maintained or disassembled
while under pressure. Only qualified personnel should change
connectors or dissemble.
WARNING: Do not disassemble the low-pressure regulator, flow-metering device,
or connector while under pressure. The release of sudden pressure may
cause injury.
WARNING: Review the specifications of the AGSS transfer and receiving systems
and the specifications of the A7 System to ensure compatibility and to
prevent a mismatched receiving system.
WARNING: Avoid connecting two or more hose assemblies in series as this may
cause a loss of pressure and flow.
WARNING: A hazard may exist due to the use of improper connectors. Ensure all
assemblies use the proper connectors.
WARNING: Avoid replacing a high-pressure flexible connection with one of lower
nominal inlet pressure.
WARNING: Reusing breathing circuits or reusable accessories that are not
disinfected may cause cross-contamination. Disinfect the breathing
circuits and reusable accessories before use.
WARNING: Inspect all breathing system components carefully before each use.
Ensure all components do not contain any obstructions or debris that
can cause a potential hazard to the patient.
WARNING: Use breathing circuits and manual bags in accordance with ASTM F1208
and compatible with standard 22mm male conical fittings per ASTM
specifications F 1054.
