Maintenance
Transducer precautions and maintenance
Do not drop the transducer on the hard surface, as this will damage
the transducer elements and compromise the electrical safety of the
transducer.
Avoid kinking or pinching the transducer cable.
Use only the approved ultrasound coupling gels.
Do not immerse the transducer into liquids beyond its binding line,
and must not immerse the transducer connector into any liquids at all
times.
Do not use damaged or flawed transducers.
Use only couplants specifically designed for ultrasound examinations.
Do not use mineral-oil or vegetable-based couplants, which can
damage transducers.
Do not expose transducers to direct heat such as strong sunlight
or local heat sources. Heat ages the crystal and causes loss of
sensitivity.
Transducers are highly-sensitive instruments and are easily
damaged due to improper operations. Use the transducers with
extra care and avoid damages when not in use.
A recommendation calling the operator’s attention to the need for
regular testing and periodic maintenance including inspection of the
transducer assembly for cracks that allow the ingress of conductive
fluid shall be provided.
Inspect the transducer
Inspect the transducer’s acoustic lens, outer cover, the cable, and
the transducer connector before each use. Check the transducer
carefully and see if there are cracks, cuts, or any other damages
which may admit fluids. Do not use the transducer if it is damaged.
If the transducer is dropped accidentally, examine it immediately for
signs for damage. Perform a sample scan to make sure it operates
correctly. Contact the Qisda dealer for service or replacement if any
abnormalities are found.
To avoid any possibilities of hurting the patient, check if the transducer
has a smooth edge and an even surface before each use.
Cleaning and disinfection
Clean the transducer and the transducer handle after use.
For surface transducers, disinfect the transducer periodically.
Keep a log of maintenance (inspection, cleaning and disinfection)
and malfunction.
