PROBLEM TO BE SOLVED : To provide a dental clinic apparatus which has a simple structure, and can perform the sterilization of contaminants in a fluid circuit. SOLUTION : The dental clinic apparatus includes a fluid conduit in which water, air and so forth to be fed to treatment instruments such as an air turbine 14 and a micro-motor 15 used for the treatment of teeth of a patient from a fluid supply source flow. At a part or the total of the fluid circuit, the conduit is formed into a dielectric pipe structure. An electric field is formed by two high electric potential electrodes which are set on the outer periphery on the upstream and the downstream of the conduit and a high-voltage power source so that discharge may occur in the longitudinal direction of the conduit by stopping the supply of a fluid such as water or air, and feeding a rare gas in the fluid circuit. Thus, a plasma jet is formed in the conduit between the two high electric potential electrodes, and the inside of the conduit is sterilized. COPYRIGHT : (C)2010, JPO&INPIT |
