DryShield performs all the tasks of a high-suction evacuator, bite block, tongue guard and oral pathway protector in one easy-to-use device. It has been engineered to be fully autoclavable. The multiple holes and passageways in the mouthpiece assist with removal of water and saliva from the oral cavity. Installation is simple, attaching directly to the HVE, no special equipment required. Isolation System: DryShield, Portable Operatory Kit, Y Connector Kit, Cleaning Brush
