Dental valve tailpiece
A tailpiece for a dental valve device is disclosed which has a body having a valve receiving end, a hose receiving end, and a hose retaining section having a hose insertion section, an inclined section, a first flat section, a first tapered ring section having a central section, a second flat section, a second tapered ring section having a central section, and a third flat section.
1. A tailpiece for a dental valve device comprising:
a body having a valve receiving end having an exterior stop surface, a hose receiving end, and a hose retaining section between the hose receiving end and the valve receiving end with the hose retaining section having a straight cylindrical hose insertion section adjacent the hose receiving end, an inclined section adjacent the straight cylindrical hose insertion section, a first straight cylindrical section having a diameter, the inclined section between the straight cylindrical hose insertion section and the first straight cylindrical section, the inclined section increasing in diameter between the straight cylindrical hose insertion section and the first straight cylindrical section with the inclined section increasing in diameter to the diameter of the first straight cylindrical section, a first tapered ring section adjacent the first straight cylindrical section having a first central fillet section, a second straight cylindrical section adjacent the first tapered ring section, the first tapered ring section having a first section that increases in taper between the first straight cylindrical section and the first central fillet section and a second section that decreases in taper between the first central fillet section and the second straight cylindrical section, a second tapered ring section adjacent the second straight cylindrical section having a second central fillet section, and a third straight cylindrical section adjacent the second tapered ring section, and the exterior stop surface for allowing a hose to abut up against the exterior stop surface and for preventing the hose from being retained by the valve receiving end, the valve receiving end having an exterior surface that flares outwardly over the entire exterior surface from the exterior stop surface to the valve receiving end.
2. The tailpiece for a dental valve device of claim 1 wherein the second tapered ring section has a first section that increases in taper between the second straight cylindrical section and the second central fillet section and a second section that decreases in taper between the second central fillet section and the third straight cylindrical section.
3. The tailpiece for a dental valve device of claim 1 wherein the valve receiving end further comprises an annular interior surface having a back stop edge to allow a dental valve to be positioned within the valve receiving end.
4. A tailpiece for a dental valve device comprising:
a body having a valve receiving end having an exterior stop surface, a hose receiving end, a lumen formed between the valve receiving end and the hose receiving end; and
a hose retaining section formed between the exterior stop surface and the hose receiving end having a straight cylindrical hose insertion section adjacent to the hose receiving end, an inclined section adjacent the straight cylindrical hose insertion section, a first straight cylindrical section having a diameter, the inclined section between the straight cylindrical hose insertion section and the first straight cylindrical section, the inclined section increasing in diameter between the straight cylindrical hose insertion section and the first straight cylindrical section with the inclined section increasing in diameter to the diameter of the first straight cylindrical section, a first tapered ring section having a first central fillet section, a second straight cylindrical section, the first tapered ring section having a first section that increases in taper between the first straight cylindrical section and the first central fillet section and a second section that decreases in taper between the first central fillet section and the second straight cylindrical section, a second tapered ring section having a second central fillet section, and a third straight cylindrical section, and the exterior stop surface for allowing a hose to abut up against the exterior stop surface and for preventing the hose from being retained by the valve receiving end, the valve receiving end having an exterior surface that flares outwardly over the entire exterior surface from the exterior stop surface to the valve receiving end.
5. The tailpiece for a dental valve device of claim 4 wherein the second tapered ring section has a first section that increases in taper between the second straight cylindrical section and the second central fillet section and a second section that decreases in taper between the second central fillet section and the third straight cylindrical section.
6. A tailpiece for a dental valve device comprising:
a body having a valve receiving end having an exterior stop surface and an interior stop surface, a hose receiving end, and a lumen formed between the valve receiving end and the hose receiving end; and
a hose retaining section formed between the exterior stop surface and the hose receiving end, the hose receiving end having a straight cylindrical hose insertion section adjacent the hose receiving end, an inclined section adjacent to the straight cylindrical hose insertion section, a first straight cylindrical section having a diameter, the inclined section between the straight cylindrical hose insertion section and the first straight cylindrical section, the inclined section increasing in diameter between the straight cylindrical hose insertion section and the first straight cylindrical section with the inclined section increasing in diameter to the diameter of the first straight cylindrical section, a first tapered ring section having a first central fillet section, a second straight cylindrical section, the first tapered ring section having a first section that increases in taper between the first straight cylindrical section and the first central fillet section and a second section that decreases in taper between the first central fillet section and the second straight cylindrical section, a second tapered ring section having a second central fillet section, and a third straight cylindrical section, and the exterior stop surface for allowing a hose to abut up against the exterior stop surface and for preventing the hose from being retained by the valve receiving end, the valve receiving end having an exterior surface that flares outwardly over the entire exterior surface from the exterior stop surface to the valve receiving end and an interior surface that flares outwardly from the interior stop surface to the valve receiving end.
7. The tailpiece for a dental valve device of claim 6 wherein the second tapered ring section has a first section that increases in taper between the second straight cylindrical section and the second central fillet section and a second section that decreases in taper between the second central fillet section and the third straight cylindrical section.
