  • Patent number: 6056260
    Abstract: This invention relates to a seamless system for controlling the flow of fluids, such as liquids or compressed air, through a non-fragmented length of flexible tubing. It incorporates into a single system a number of functions currently performed with separate valves within conventional dental handpiece fluid flow control units. The invention can be fitted to an existing flexible fluid supply line, within a dental delivery system without destructive insertion or removal of any intermediary parts and without contact with the fluid medium itself. The invention is conceived to accommodate from the outside, three contiguous portions (a first, an intermediate and a second portion) of a non-fragmented length of flexible tubing.
