Description

  The present invention relates to a dental instrument, and more particularly, to a dental instrument having a water circuit, in which bacteria are prevented from entering the water circuit from the open end of the water circuit. .

  FIG. 3 is a schematic overall configuration diagram for explaining an example of a dental treatment unit to which the present invention is applied. In the figure, 10 is a dental treatment unit, and the unit 10 includes a treatment chair 1, a work table 2, and a spittoon. 3. Gargle water injection tube 4, surgeon instrument holder 5, surgeon instrument 6, instrument hose 7, assistant instrument holder 8, etc., instrument holder 5 Accommodates various instruments 6 used in dental treatment, and as is well known, during dental treatment, a patient sits on a chair 1 and his head is fixed to an abutment base 11 for treatment. . During the treatment, the surgeon moves the treatment chair 1 up and down, tilts and tilts to make the patient easy to treat, pulls out the instrument 6 from the instrument holder 5 and performs treatment.

  The assistant holder 8 is provided with a syringe, a vacuum tube, a saliva discharge tube 9 and the like, and at the time of treatment, the assistant cleans the patient's oral cavity, or sucks sewage, saliva, etc. generated in the patient's oral cavity.・ It is trying to discharge. The assistant holder 8 is of a stand-alone type, but as shown in the figure, there is also a case where the assistant holder 8 is fixed to a fixing member, for example, a spitone water supply / drainage box 13 through an arm 12.

  As described above, in the dental treatment unit, the operator takes out the instrument 6 from the instrument holder 5 and, for example, takes out the air turbine and performs tooth cutting. Water is jetted from the area to cool the treatment site, and the assistant cleans the patient's oral cavity by taking out, for example, the syringe 9 from the assistant holder 8.

  As described above, in the dental treatment unit, water is injected into the patient's oral cavity through the water circuit in the instruments 6 and 9, or when gargle, the gargle water is discharged from the gargle water injection tube 4. It is practiced to gargle the oral cavity with gargling water.

  Thus, the instruments 6 and 9 etc. are suspended by the instrument holders 5 and 8 etc., and in the meantime, bacteria etc. enter the water circuit of these instruments 6 and 9 from outside air. However, the bacteria propagated in the water circuit of the instrument, and these bacteria entered the patient's mouth the next time the instrument was used and were unhygienic. The same can be said for the gargle water injection pipe 4. When not in use, bacteria enter the gargle water injection pipe 4 from the outside and propagate in the water circuit communicating with the gargle water injection pipe 4. When gargling, the bacteria entered the patient's mouth and were unhygienic.

  The present invention has been made in view of the above-described circumstances, and in particular, in a water circuit in a dental device, bacteria are prevented from entering the water circuit from the outside (outside air). It is an object of the present invention to provide a dental instrument that can prevent bacteria from growing inside and can perform hygienic dental treatment.
