摘要:
A dental device that mates a high volume extraction unit to a tongue retractor to allow the dental assistant to remove fluids and debris from the mouth of a patient with ease and using a minimal volume of the space in a patients mouth. The device has a straw collar that encircles the shaft of a suction straw in a “Vee” configuration with a set of opposing half-bands. A post extending inward from the front half band locks the suction straw in place. Affixed to the suction straw is a paddle shaped tongue retractor with an array of orifices there through to allow the vacuuming of fluids and debris from the bottom side of the retractor.
