Chapter 6 Maintenance and Cleaning   

6.1 Maintenance   

6.1.1Checking Before Using   

■ 

Check the patient monitor for mechanical damages;   

■ 

Check all exposed conductors, connectors and accessories;   

■ 

Check all functions that are possibly enabled for the monitored patient, and                  

ensure the device is in good working status. 

In case of any damage, stop using this patient monitor, and contact biomedical 
engineers of the hospital or Mindray maintenance engineers.   

6.1.2 Regular Checking   

An all-around check, including the safety check, should be done by qualified personnel 
every 6-12 months or after maintenance each time. 
All checks in which the patient monitor should be disassembled should be done by 
qualified maintenance personnel. The safety and maintenance checks can be done by 
Mindray engineers. The local office of Mindray at your region will be pleased to provide 
you with the information about the maintenance contract.   

6.2 Cleaning  

Do switch off the patient monitor and disconnect the AC power supply before 

cleaning it or the probes.   

The PM-9000 Express patient monitor should be dust free. To clean the surface of its 
enclosure and screen, use the cleaning agent that is not corrosive, for example, soap 
and water.   

1.    Do not use strong solvent, such as acetone; 

2.    Most cleaning agents must be diluted before being used, so conduct dilution under 

the instruction of manufacturers;   

3.    Do not use any erosive material (such as steel wool or polishing agent); 

4.    Prevent the ingress of any liquid to the enclosure and any part of the device;   

5.    Ensure no residue of cleaning liquid on the surface of the device.   

6.3 Cleaning Reagent 

1.    Diluted aqua ammonia 

2.    Diluted sodium hypochlorite (bleaching powder for washing) 

3.    Diluted formaldehyde 35 – 37% 

4.    Hydrogen peroxide 3%
