Description

[Detailed Description of the Invention] The present application relates to a dental treatment chair equipped with an auxiliary device, and in particular, a dental treatment chair equipped with an auxiliary device so that a patient can easily get on and off the treatment chair.

In dental treatment, the treatment chair is usually set so that the patient gets on and off from the position on the left side when facing the treatment chair, but the treatment table and treatment instruments are arranged in the treatment room or in a seated position so that the treatment chair can be placed in a position that is most convenient for treatment. When setting the patient on the left side of the treatment chair, it is necessary to get the patient in and out of the treatment chair on the right side.

However, if the right side of the treatment chair is equipped with auxiliary equipment such as a water spout, a vomiting device used exclusively by an assistant, a vacuum, and a spray syringe, it will be difficult for the patient to get on and off the chair.

Therefore, the present application is intended to improve such defects, and the embodiment thereof will be described in detail below with reference to the drawings.
Reference numeral 1 denotes a chair body installed on elevating legs 2, and is provided with a backrest 3 that can be raised and lowered as is well known. Reference numeral 4 denotes a cylindrical support that is disposed on the right side of the chair body 1 and extends upward, and its base 4' is bent inward and extends horizontally.
It is supported so as to be movable in the front and rear directions via a guide mechanism 5. The guide mechanism 5 includes a guide shaft 6 that is long in the front-rear direction and passes through the base 4' of the column 4.
and a screw shaft 7 screwed into the base 4', and brackets 8, 8 supporting both ends of the guide shaft 5.
The screw shaft 7 is rotatably supported. One end of the screw shaft 7 protrudes from one bracket 8, and a drive wheel 9 (not shown), which is rotated by a drive motor provided at the bottom of the pedestal via a belt or a dental mechanism, is supported on this protrusion, for example. . The support column 4 thus moves along the guide shaft 6 from one end to the other due to the rotation of the drive wheel 9.

A discharge bowl 10 is provided on the upper part of the support 4,
Further, a support 15 equipped with a discharge tool 12, a spray syringe 13, and a vacium nozzle 14, respectively, is attached to the lower part of the water spouting bowl 10 via a horizontally extending support rod 11 so as to be horizontally rotatable. 16 is a flexible hose.

However, in the treatment position where the patient is seated on the chair body 1, the support column 4 is moved to the state shown by the solid line in the figure.
When the patient gets off the chair body 1, the patient moves to the position shown by the imaginary line in the figure.

In the above, the screw shaft 7 may be rotated manually, or the screw shaft 7 may be replaced with a guide shaft and the support 4 itself may be moved along two guide shafts. Of course, it may be configured to be automatically movable by a combination of a pressure fluid actuating body and a link piece.

Furthermore, although the above embodiment shows the case where the support is installed on the right side of the chair body, in the treatment room, for example, the chair body may be placed with the right side close to the indoor wall. In such a case, the support column will be installed on the left side of the chair body on which the patient gets on and off the chair so as not to interfere with its placement.

Since the present application is configured as described above, even if the treatment chair is equipped with a support at the side position where the patient gets on and off, the patient can get on and off without any problem.
It has the advantage that auxiliary devices can be used effectively during treatment.
