SAFE-FLO® Saliva Ejector Valves from Crosstex are a one-way check valve to prevent back flow from the saliva ejector. The user inserts any standard saliva ejector into the end of the SAFE-FLO SE valve and when the On/Off vacuum switch is opened, the  system sucks air through the check valve and the aspirator tip. The check valve opens in the direction of air and fluid flow. If the suction is stopped or blocked, the check valve closes and stops air and fluid from returning to the aspirator tip or the patient.

Item includes: Bag  of 100 SAFE-FLO Valves
