10.1.1 Maintaining Inspection
(1) Visual Inspection
Prior to using the monitor, perform the following inspections:
1. 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 seams on the transducers and cables
before immersing them into conductive fluid.
2. Check all the outer cables, power socket and power cables.
3. Check if the monitor functions properly.
If any damage is detected, stop using the monitor. Replace the damage part(s) or contact Wallach
Surgical Devices 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 live
parts. 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.
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.
10.1.2 Maintenance of Monitor
Keep the exterior surface of the monitor clean and free of dust and dirt.
The appearance of moisture on the screen may occur with abrupt temperature or humidity
changes. A stable environment is recommended.
Avoid scratching and damaging the screen.
