2. Description of the Related Art In a dental treatment room, many outpatients come and go,
If care is not taken to effectively sterilize and disinfect the room, a large number of microorganisms may remain on the floor, surfaces of instruments and appliances, or in the air. It may become a place for transmission of pathogenic microorganisms from the patient to the operator or from the operator to the patient. On the other hand, since various miscellaneous microorganisms inhabit the oral cavity of humans, there is a risk that secondary infection due to oral resident microorganisms will occur due to dental treatment. Infection is attracting attention. Therefore, in dental treatment, it has recently been proposed to use a vacuum device to protect the operator from airborne dust and bacteria, and to catch airborne dust and bacteria that leak from the patient's mouth to the outside during medical treatment at the patient's mouth. ing.

FIG. 2 shows an operator who effectively utilizes a vacuum device incorporated in a dental treatment unit, an arm of a surgical light, or an arm of a work table to catch floating dust at the patient's mouth. FIG. 1 is a diagram showing an example of a dental treatment unit capable of protecting the health of the user. As is well known, the dental unit 10 includes a treatment chair 1, a work table 2, a spittoon 3, a surgical light 4, a water supply / drainage and vacuum unit 5.
And the like, and the water supply / drainage device provided in the unit 5 (in the case of the illustrated example, the treatment chair 1 and the water supply / drainage / vacuum unit 5 are independently configured separately),
For example, water for gargle is supplied, cooling water for instruments is supplied, or water for spraying is supplied, and further, by a vacuum device provided in the unit 5, for example, The waste excreted in the spittoon 3, saliva in the patient's mouth, or cutting powder generated in the patient's mouth during treatment is sucked.

The dust attracted nearby and floating in the patient's mouth is effectively sucked.

[0005]

Therefore, according to the above-mentioned conventional dental treatment unit, in order to bring the intake port to the vicinity of the patient's oral cavity, the operating light must be moved at the same time. This moving operation is performed by the surgeon, so the burden on the surgeon is large, and even if you try to only inhale, the shadowless lamp is always attached together, so the environment around the patient's oral cavity is not clean, There was a problem that it was difficult to perform the operation. Moreover, since the surgical light and the intake port are always in front of the patient, there is a problem that the patient feels intimidated.

[0006]

In order to solve the above-mentioned problems, the present invention provides (1) for an assistant having one end connected to a spitton body or a water supply / drainage box and the other end having an instrument holder for an assistant attached thereto. In a dental treatment unit having an arm movably, an intake port is provided at the tip end, and the other end has a vacuum device in communication with the spittoon body or the water supply / drainage box, and the vacuum device together with the assistant arm. (2) The vacuum device has a ventilation arm that communicates from the intake port to the spittoon body or the water supply / drainage box, and the ventilation arm is provided in parallel with the assistant arm. In addition, (3) the assistant arm and / or the ventilation arm is a flexible tube. Further, (4) the assistant arm also serves as a part of the ventilation arm, and (5) the assistant for adjusting the distance from the spitton body or the water supply / drainage box. The length of the extension arm and / or the ventilation arm from the spittoon body or the water supply / drainage box is adjustable, or (6) one end is connected to the water supply / drainage and vacuum unit and the other end has an assistant instrument. In a dental treatment unit having an assistant arm to which a ment holder is attached movably, it has an intake port at its tip and the other end has a vacuum device communicating with the water supply / drainage and vacuum unit. It is characterized in that it moves together with the assistant arm.

1 is a perspective view of an essential part for explaining an embodiment of a dental treatment unit according to the present invention, in which 10 is a dental treatment unit, 11 is a treatment chair, and 12 is an arm for a work table. , 13 is a spittoon, 14 is a water supply / drainage box, and 15 is a spitton main body. In the illustrated example, the spitton main body 15 is attached to the treatment chair 11 and is configured separately from the water supply / drainage box 15. However, functionally, it has the same function as that of the water supply / drainage and vacuum unit 5 shown in FIG. Therefore, the water supply / drainage box 14 and the spittoon body 15 are, for example, the same as the water supply and vacuum unit 5 in the prior art shown in FIG. The cooling water of the instrument is supplied, or the water for spraying is supplied, and further, by the vacuum device provided in the main body of the spittoon, for example, the waste excreted in the spittoon 13 and the patient The saliva in the oral cavity or the cutting powder generated in the oral cavity of the patient during treatment is sucked.

Reference numeral 16 is an instrument holder for an assistant, and the instrument holder 16 for an assistant comprises a holder portion 16a, a handle portion 16b, and an operation panel portion 16c. As described above, the instruments such as saliva drainage tubes, vacuum tubes, and spray syringes used by the assistant are suspended. These instruments are connected to the spitton main body 15 through a flexible hose, and an assistant drives these instruments by operating a push button or the like on the operation panel 16c, and, for example, in the oral cavity during treatment. The saliva or the like generated in the above is sucked and discharged, or a spray or the like is sprayed into the oral cavity to clean the oral cavity.

The assistant instrument holder 16 has an arm 17 for an assistant instrument holder, one end of which is connected to the spittoon body 15.
It is fixed or pivotably attached to the arm 17 for the assistant instrument holder.

Moreover, the intake port 18 is attached so as to be tiltable in the arrow F direction by a bellows mechanism or the like so that when the treatment chair is tilted, the position and orientation of the intake port 18 can be adjusted to the oral position of the patient. You can do it.

In the above description, the case where the suction arm 19 of the vacuum device is provided side by side with the arm for the assistant instrument holder has been described, but the present invention is not limited to the above-mentioned embodiment. It is also possible to share the spittoon body 15 to the assistant instrument holder 16 and use only the extension after that, that is, the assistant instrument holder 16 to the intake port 18 as the intake arm. In other words, it is possible to attach the assistant instrument holder 16 to the intake arm 19 of the vacuum device, which not only simplifies the structure and lowers the cost. , The assistant area can be made cleaner.

In the above, the spittoon body 15 is integrally attached to the treatment chair 11, and the water supply / drainage box 14 is attached.
A case in which the present invention is applied to a dental treatment unit configured separately from the above will be described. However, the present invention is not limited to the illustrated embodiment, and for example, as shown by a chain line I in the drawings, The arm 17 for the assistant instrument holder may be attached to the water supply / drainage box 14, and the above-mentioned intake arm 19 may be added to the arm 17.

In the above, an example in which a vacuum device such as a vacuum pump is built in the water supply / drainage box 14 has been described, but when a central vacuum system is used, as shown by a chain line II in the figure. In addition, the vacuum device may be commonly used for all treatment units by piping from the central vacuum device. Further, the case where the present invention is applied to the dental treatment unit in which the spittoon body 15 and the water supply / drainage box 14 are separately configured has been described above. However, like the dental treatment unit shown in FIG. It can be easily understood that the present invention can be applied to a water supply / drainage and vacuum unit in which the box is integrally configured and is separate from the treatment chair.
