Safety test overview (continued)
Prior to initiating any electrical test, the Ultrasound system must
be visually inspected. Perform the following visual checks:
• Check for missing or loose enclosure covers that could
allow access to internal live parts.
• Examine the mains cord, mains plug and appliance inlet for
damaged insulation and adequacy of strain relief and cable
clamps.
• Locate and examine all associated transducers. Inspect the
cables and strain relief at each end. Inspect the transducer
enclosure and lens for cracks, holes and similar defects.
Test the system, peripherals and probes for leakage current.
Excessive leakage current can cause injury or death in sensitive
patients. High leakage current can also indicate degradation of
insulation and a potential for electrical failure. Do not use probes
or equipment having excessive leakage current.
To minimize the risk that a probe may shock someone the
customer should:
• Not use a probe that is cracked or damaged in any way.
• Check probe leakage current:
• Based on your facilities QA program for surface probes.
• Based on your facilities QA program for endocavitary
probes.
• whenever probe damage is suspected.
