Chapter 5 Maintenance

5.1 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.
