According to the CDC, studies indicate that backflow in low-volume suction lines can occur and microorganisms present in the lines can be retracted into the patient’s mouth, when a seal around the saliva ejector is created, or when a length of the suction tubing holding the tip is positioned above the patient’s mouth. This backflow can be a potential source of cross-contamination. SAFE-FLO salivia ejectors and valves makes it easy for dental professionals to avoid the risk of exposing patients to saliva, blood and other potentially infectious material from previous patients, and is available as an all-in-one saliva ejector or as an add-on for your customer’s favorite SE or HVE tips.
