Abstract:
A deformable disposable high volume dental aspirator comprising:a) a flexible conduit for the transmission of aspirated fluids comprising a tubular peripheral sidewall and an evacuation chamber formed by said sidewall; b) a means for selectively deforming said flexible conduit comprising a resilient wire member that is longitudinally integral with said conduit and provides semi-rigid characteristics thereto allowing a user to quickly and easily manipulate said conduit into a desired shape and have it remain in that shape until further manipulation by the user; c) a means for diffusing suction during high volume aspiration comprising a substantially cylindrical peripheral housing, a suction channel formed by said housing, a first end of said housing for sealably engaging with said flexible conduit, furcations projecting longitudinally toward a second end of said housing, evacuation recesses formed between said furcations, and retaining flanges extending medially from the distal ends of each said furcation terminating such as to form a central opening communicating with said evacuation recesses; d) a substantially disc-shaped suction tip member mounted inside said housing adjacent said flanges such that said flanges overlap and hold in place said suction tip member, said suction tip member having a central recess passing therethrough; and e) means for connecting said flexible conduit to a vacuum valve.
