The BACSTOP™ dental waterline Anti-retraction valve is normally closed disposable valve, which is replaced every week, or 5 working days. It is intended to be used in-line on dental unit water lines as a means of preventing the retraction of orally contaminated fluids into the coolant and irrigant water hoses. It is to be used for all patients.

BACSTOP™ is to be installed within the last several inches of tubing, before the dental handpiece, air/water syringe or ultra sonic scaler. It opens only under sufficient pressure (equivalent to 1.5 psi) and snaps closed and seals against backflow when the pressure drops below this point. The device is inserted by connection to luer mounts placed permanently in-line.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
