Maternity Transducer Belt This belt is used to secure the probe (transducer) during a Non-Stress Test (NST), a fetal monitoring test. Due to infection control measures like those for COVID-19, pregnant women were required to purchase their own for individual use. I used it about 10 times before giving birth in April 2025. I have safely given birth and do not plan to become pregnant again, so I am selling it. I have discarded the original packaging. I have washed it at home, dried it thoroughly, and stored it in a zip-lock bag. The edges appear to be frayed, but it was like this when I bought it, and it doesn't seem to fray further. In my case, I was carrying a single baby, so one set was sufficient. However, if you are carrying multiple babies, you will need one belt per baby (number of babies x 1 belt). (Your hospital will likely explain this.) 【Product Description】 - Color: Pink and Green (Set of 2) - Purpose: Probe belt - Material: Stretchy material - Size: Approximately 6cm wide - Features: Foldable and compact Thank you for looking.
