that patients can experience allergic reactions with natural rubber latex. See
"FDA Medical Alert on Latex" on page 45.
NOTE
The ultrasound system and transducers discussed here do not contain natural
rubber latex that contacts humans. Natural rubber latex is not used on any Philips
ultrasound transducers.
Preventing TEE Transducer Problems
Meticulous inspection and correct and careful operation of the TEE
(transesophageal) transducer is imperative to patient safety. The situations listed
here affect safe operation as well as the ability to service mechanical problems
under the Philips one-year warranty or service contract. Transducer repairs
necessitated by misuse of the transducer are not covered and can be very costly,
often requiring complete disassembly and rebuilding of the transducer.
There are three primary areas of transducer misuse:
• Cuts and abrasions on the transducer and insulation from teeth or sharp
instruments such as scalpels, scissors, and clamps
• Improper disinfection techniques, causing fluid to enter the control head
assembly, transducer handle, and the rest of the transducer
• Consistently applying too much force to the control wheels of a TEE
transducer, which can break the steering mechanism
Review the following table to familiarize yourself with specific problems, to learn
how to avoid them, and to identify the sections in this manual where details are
provided. Philips also strongly recommends that you clearly post stringent
protocols for TEE transducer care, based on the information in this manual, to
minimize the chance of damage.
WARNING
For any other irregularity not listed in the following table, do not use the
transducer. Potentially serious consequences could result. Contact your Philips
representative.
