Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dental chair unit.

[0002]

[Prior art]

 In the past, when performing cutting work in the oral cavity of a patient, bacteria and the like possessed by the patient may be scattered in the air together with cutting powder, which has been a problem of infection to a dentist or a dental hygienist. Further, when the cutting work is performed on the chair side for fine adjustment of the prosthesis, there is a problem that cutting powder is scattered in the treatment room and the treatment room cannot be kept clean.

In order to deal with these problems, there has been a dust collector using a suction device until now, but when a dentist wants to use this dust collector during treatment, he / she must remove the dust collector. Not only is it cumbersome to handle because it is necessary to walk around, but since this device is relatively large, it occupies space and is an obstacle when not in use.

[0004]

[Problems to be solved by the device]

 The present invention prevents these problems, namely, scattering of cutting powder during cutting work in the oral cavity of a patient or scattering of bacteria etc. possessed by the patient to prevent infection to a dentist or dental hygienist. It is an object of the present invention to obtain a dust collector that can prevent the cutting powder from scattering in the cutting work for fine adjustment of the prosthesis, clean the treatment room, facilitate handling, and save space. To do.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a dust collecting pipe provided at the tip and made of a hard flexible tube is rotatably attached to the upper portion of the chair base of the dental chair unit to collect dust. When not in operation, the dust collecting pipe is stored outside the chair base, that is, `` a chair including a seat, a backrest, a headrest, a footrest and a dental chair unit including a chair base, A dust collection pipe consisting of a flexible tube connected to the dust collection device with a dust collection cup at the tip is rotatably attached to the upper part of the chair base.When the dust collection work is not performed, the dust collection pipe of the chair base is A dental chair unit characterized in that it is configured to be stored in the upper part.

[0006]

[Action]

 When performing the cutting work in the patient's oral cavity, the dust collecting pipe and the dust collecting cup according to the present invention are placed near the patient's mouth to perform the dust collecting work, and the cutting work for fine adjustment of the prosthesis is performed. When performing, the dust collecting pipe and the dust collecting cup according to the present invention are located near the cutting work position to perform the dust collecting work. Also, when the dust collection work is not performed, store the dust collection pipe in the upper part of the tire base.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a state in which the dust collecting device of the dental chair unit of the present invention is used. This dental chair unit is composed of a chair 1 including a seat 3, a backrest 4, a headrest 5 and a footrest 6, and a chair base 2.

A dust collecting cup 7 is attached to the upper end of the chair base 2, and a dust collecting pipe 8 made of a hard flexible tube such as a metal corrugated pipe is attached by a rotary connecting portion 9. There is. Further, inside the chair base 2, a dental chair unit control unit, a chair drive unit (neither shown), and a dust collector 10 for both wet and dry are built in, and the dust collector 10 has a rotary connection unit. The dust collecting pipe 8 is connected via 9 An operation unit 11 such as a switch for operating the dust collecting device is provided at the end of the dust collecting pipe 8 on the dust collecting cup side.

When using this dust collector to collect the cutting powder during the cutting work in the patient's oral cavity, the dust collecting cup 7 and the dust collecting pipe 8 are positioned at the position A shown by the solid line in the figure, When collecting the cutting powder during the cutting operation during fine adjustment of the prosthesis, the dust collecting cup 7 and the dust collecting pipe 8 are located at the position B shown by the dotted line in the figure.

FIG. 2 shows the storage state of the dust collecting cup 7 and the dust collecting pipe 8. When the dust collecting operation is not performed, the dust collecting cup 7 and the dust collecting pipe 8 are stored at the position C on the upper portion of the chair base 2.

Next, another embodiment of the present invention different from the above embodiment will be described. The dust collecting pipe 8 is composed of a hard flexible tube such as a metal corrugated pipe, a hard flexible tube of synthetic resin or the like, or a soft flexible tube, and is arranged near the working position by an appropriate means. You may. The dust collector 10 may be a dry-wet type or a dry-type only. The dust collector 10 may be installed not only inside the chair base 2 but also outside the chair base 2 or in a machine room separate from the treatment room and connected to the dust collecting pipe 8 via an underfloor pipe. . The mounting position of the operation portion 11 may be the backrest 4 or the chair base 2 in addition to the end of the dust collecting pipe 8 on the side of the dust collecting cup 7. In that case, the dust collecting device may be provided near the storing position of the dust collecting pipe 8. The dust collecting device 10 may be automatically operated by providing the switch 10 and moving the dust collecting pipe 8 from the storage position to perform the dust collecting operation.

[0012]

[Effect of device]

 In the dental chair unit of the present invention, the dust collecting cup 7 and the dust collecting pipe 8 for collecting the cutting powder are attached to the chair base 2 by the rotary connection portion 9, so that the cutting powder for the cutting work in the patient's oral cavity is Prevents splattering or bacteria contained in the patient from infecting dentists or dental hygienists, and in order to make fine adjustments to the prosthesis, a cutting room to prevent scattering of cutting powder during cutting work. Can be cleaned, is easy to handle, and saves space.
