<p>A transparent dental tube unit (1) contains a transparent turbine gas supply passage (3) for allowing a pressurized gas supplied from a pressurized fluid supply source to be passed to a dental handpiece for driving a turbine provided in the handpiece, a transparent liquid supply passage (5) for allowing a pressurized liquid from the pressurized fluid source to be passed to the dental handpiece for dissipating heat generated by friction, a transparent enclosure tube (2) for enclosing the transparent turbine gas supply passage (3) and the transparent liquid supply passage (5) therein, and a fixing device (8, 9) for fixing the transparent turbine gas supply passage (3) and the transparent liquid supply passage (5). <IMAGE></p> |
