Guidelines for checking your transducers

ProbeLogic recommend the following test procedure as a guideline before every use. If a probe is found to fail any of these guidelines it is recommended that the probe not be used and a full transducer test be performed by a qualified ProbeLogic representative.
Scrutinize the entire transducer and test all controls (if relevant) including inspections of the case, cable and connector. In the case of TEE probes carefully inspect the entire surface of the insertion tube, distal tip and lens checking for protrusions, holes, dents, abrasions, cuts, burrs or cracks to ensure that no damage is present. Obviously this is very important for your safety and the safety of your patient.
If your transducer type requires disinfection of the probe after each use, it is recommended a visual inspection be performed before the disinfection process, to ensure there is no damage that could allow fluid ingress into the probe. If fluid ingress does occur, do not connect the transducer to the machine as this could cause electrical damage to the probe internals. Send the probe to us as rapidly as possible as there is a very good chance that the probe can be repaired before corrosion begins.
Electrical leakage test your transducers. This is especially important on TEE transducers where the electrical leakage limit is 180uA. On general imaging transducers the leakage limit is 500uA but most transducers will measure below 50uA if there are no problems.
When using TEE transducers, ALL PATIENTS SHOULD WEAR BITE GUARDS. This protects against mechanical and electrical malfunction in the event of involuntary biting. Even anesthetized patients require bite guards to prevent damage to both their teeth and the transducer.
Following these recommendations as well as any recommendations from the manufacturer will help to reduce costs by diagnosing and repairing faults before they turn into major repairs.
