Chapter 10 Maintenance and Cleaning
10.1 Maintenance
10.1.1 Maintaining Inspection
1) Visual Inspection
Prior to using the monitor every time, do the following inspections:
Check the monitor and accessories to see if there is any visible evidence of damage that may affect
patient safety. Pay special attention to the cracks on the transducers and cables before immersing
them into conductive fluid.
Check all the outer cables, power socket and power cables.
Check if the monitor functions properly.
If any damage is detected, stop using the monitor on the patient. Replace the damage part(s) or
contact the manufacturer for service before reusing it.
2) Routine Inspection
The overall check of the monitor, including safety check and function check, should be performed by
qualified personnel every 6 to 12 months, and each time after service.
The equipment should undergo periodic safety testing to ensure proper patient isolation from leakage
currents. This should include leakage current measurement and insulation testing. The recommended testing
interval is once a year or as specified in the institution’s test and inspection protocol.
3) Mechanical Inspection
Make sure all exposed screws are tight.
Check the external cables for splits, cracks or signs of twisting.
Replace any cable that shows serious damage.
Pay particular attention to the supply socket.
WARNING:
Failure on the part of the responsible individual hospital or institution employing the use of this equipment to
implement a satisfactory maintenance schedule may cause undue equipment failure and possible health
hazards.
CAUTION:
Besides the maintenance requirements recommended in this manual, comply with local regulations on
maintenance and measurement.
10.1.2 Maintenance of Monitor
Keep the exterior surface of the monitor clean, and free of dust, dirt and residual liquids. Clean with a damp
cloth using mild soap and water or hospital approved non-abrasive disinfectants.
The gathering of dew on the screen may occur with abrupt temperature or humidity changes. A table
environment is recommended. Stop using the monitor and contact the service personnel immediately if
accidental wetting occurs.
