Preparing transducers WARNING:
Some transducer sheaths contain natural rubber latex and talc, which can cause allergic reactions in some individuals. Refer to 21 CFR 801.437, User labeling for devices that contain natural rubber. Some gels and sterilants can cause an allergic reaction on some individuals.
Caution:
To avoid damage to the transducer, use only gels recommended by SonoSite. Using gels other than the one recommended by SonoSite can damage the transducer and void the warranty. If you have questions about gel compatibility, contact SonoSite or your local representative. SonoSite recommends that you clean transducers after each use. See “Cleaning and disinfecting transducers” on page 58.
Acoustic coupling gel must be used during exams. Although most gels provide suitable acoustic coupling, some gels are incompatible with some transducer materials. SonoSite recommends Aquasonic® gel and provides a sample with the system. For general use, apply a liberal amount of gel between the transducer and the body. For invasive or surgical use, apply a transducer sheath. For information about preparing the TEEx transducer, see the TEEx Transducer User Guide.
WARNING:
To prevent contamination, the use of sterile transducer sheaths and sterile coupling gel is recommended for clinical applications of an invasive or surgical nature. Do not apply the transducer sheath and gel until you are ready to perform the procedure.
To apply a transducer sheath SonoSite recommends the use of market-cleared, transducer sheaths for intracavitary or surgical applications.To lessen the risk of contamination, install the sheath only when you are ready to perform the procedure. 1 Place gel inside the sheath. 2 Insert the transducer into the sheath. 3 Pull the sheath over the transducer and cable until the sheath is fully extended. 4 Secure the sheath using the bands supplied with the sheath. 5 Check for and eliminate bubbles between the face of the transducer and the sheath. Bubbles between the face of the transducer and the sheath may affect the ultrasound image.
