Chapter 6 Maintenance 

6.1 Maintenance 

You must check that the equipment does not have visible evidence of damage that may affect the 

patient and the operator’s safety or the Doppler’s capability before each use. Pay special attention 

to the cracks on the probe and the cable before immersing them into conductive fluid. If the 

damage is evident, replacement is recommended. 

The probe is frangible and must be handled with care. 

Wipe the remaining gel after use to prolong the probe life. 

The overall check of the Doppler, including safety check and function check, should be 

performed by qualified personnel every 12 months, and each time after service. Besides the above 

requirements, comply with local regulations on maintenance and measurement. 

6.2 Cleaning 

Before cleaning, switch off the Doppler. 

Keep the exterior surface of the device clean and free of dust and dirt.   

Clean the exterior surface (display screen included) of the main unit with a dry, soft cloth. If 

necessary, clean it with a soft cloth soaked in soap water and then wipe it dry with a dry cloth 

immediately. 

Wipe the remaining coupling gel off the probe. Clean it with a soft cloth dampened in solution 

(soap water, 70% ethanol or isopropranol alcohol) and then air-dry it or wipe the moisture with a 

soft dry cloth. 

CAUTION 

1  Clean the main unit with soap and water only. Avoid strong solvent, such as acetone. 

2  Never use an abrasive such as steel wool or metal polish. 

3  The main unit is not waterproof. Do not immerse any part of it into liquid. 

4  Avoid pouring liquids on the main unit while cleaning. 

5  Do not remain any solution on the surface after cleaning. 

6  Only the body and cable of the probe are waterproof. Do not immerse the probe 

socket into any liquid. 

6.3 Disinfection of the Probe 

Clean the probes as above. Immerse them into the solutions of Benzalkonium Bromide, 0.5% 

Chlorhexidine, 2% Glutaraldehyde or 75% ethanol, and then wipe them with a clean, dry cloth to 

remove the remaining moisture.
