Pratt Urethral 11 Inch Sounds
This set consists of 8 sounds, graduated in size. Their medical purpose is to dilate the cervix, but they can also be used to clear blocked areas in the urethra. They are 11.5" long and are very similar to the hegar set. Made of stainless steel, so it is safe and easy to clean and sterilize. The sizes range from .170 inches to .445 inches in diameter. The tubes come packaged in a high-quality, velvet lined zippered pouch.
