9 - 16 WS80A Service Manual
Using Sheaths
Sheaths are recommended for clinical applications of invasive nature, including intraoperative,
transrectal, transvaginal, and biopsy procedures, during which the sheath prevents material from the
human body from contaminating the probe.
Samsung Medison does not supply sheaths, so appropriate sheaths should be purchased
independently.
WARNING
■ Always keep sheaths in a sterile state.
■ Sheaths are disposable. Do not reuse them.
■ If sheaths are torn or soiled after use, clean and disinfect the probe.
■ In neurosurgical applications, a disinfected probe must be used with
sterile gel and a sterile pyrogen-free sheath.
■ If the sterile sheath becomes compromised during neurosurgical
applications involving a patient with Creutzfeldt-Jakob disease, the probe
cannot be successfully sterilized by any disinfection method.
■ Some sheaths contain natural rubber latex and talc, which may cause
allergic reactions in some individuals. Please refer to the FDA Medical
Alert released on March 29, 1991.
▌ Installing the Sheath
1. Put on sterile gloves. Unpack the sheath and fill it with acoustic coupling gel.
2. Insert the probe into the sheath and pull the latex tip to cover the probe completely. If
possible, cover the probe cable as well.
3. Ensure that there are no air bubbles within the ultrasound gel. If necessary, secure the
sheath to the probe and the probe cable.
4. Dispose of the sheath after use.
