2. Description of the Related Art FIG. 4 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, 1 is a dental treatment chair, 2 is a spittoon body, 3 is a bowl portion, 4 is a dental treatment work table for an operator used by a doctor, 5 is an instrument holder for an assistant used by an assistant, 6 is an instrument, and 7 is a base part. Sit on chair 1 and fix his head on an armchair to receive treatment. In the dental treatment, the doctor (operator) knocks down the treatment chair 1 and
Alternatively, further, the entire chair is tilted and moved up and down to make it easy to treat, and then the treatment is performed from the back side or side of the patient's head.

In addition, in dental treatment, an assistant uses a syringe, a vacuum, or the like to perform auxiliary work such as cleaning of the oral cavity. The dental treatment unit has an instrument holder 5 for assistant for that purpose. , The assistant instrument holder 5 is located on the side opposite to the surgeon's work table 4 (with the instrument holder) on the head side of the patient, but as described above, When the instrument holder 4 for the surgeon is arranged for the left-handed person, the position of the instrument holder 5 for the assistant must be changed accordingly, which is a difficult task.

As a dental unit in which the assistant instrument holder 5 is used for both left and right, conventionally, as shown in FIG. 4, the assistant instrument holder 5 is rotatably attached to the spittoon body 2. However, it was necessary to remove the contour sheet 1a of the dental treatment chair 1 in order to change the left and right positions and rotate the main body of the spittoon, which took time, and in fact, it was decided to be placed in either one.

A dental treatment unit in which an assistant arm is rotatably attached to a chair pedestal has also been proposed, but an instrument holder for an assistant is used when the physique of patients is different or different doctors use it. Moved up and down as the chair moved up and down, and the assistant couldn't use the assistant's instrument holder at the same height, and the height changed each time, which made assisting work very inconvenient.

The present invention has been made in view of the above circumstances, and (1) simply switches the left and right by rotating the arm of the assistant instrument holder and moving the operator work table left and right. (2) 4
An ideal assist position can be set for hand (doctor and assistant) treatment (whether a right-handed doctor or a left-handed doctor, the assistant's instrument is symmetrical to the head rest) (Holder can be installed), (3) The height of the instrument holder for assistant does not change depending on the height of the dental treatment chair, and it is possible to assist at the same height position at any time. is there.

It has a table and an instrument holder for an assistant, and a supporting arm of the instrument holder for an assistant is rotatably attached to a base portion of the dental treatment chair at a lower portion of a substantially central portion of the dental treatment chair. The dental treatment work table for an operator is attached, is connected to the base portion via a flexible hose, and is movable by a caster.

According to the invention of claim 2, a dental treatment chair, a dental treatment chair lifting device for moving the dental treatment chair up and down at a side portion of the dental treatment chair, a dental treatment work table for an operator, and an assistant in-vehicle. A support arm of the instrument holder for an assistant and a support arm of the dental treatment arm for an operator are provided at a lower portion of a substantially central portion of the dental treatment chair. It is characterized in that it is coaxially and rotatably attached to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an overall schematic configuration diagram for explaining an embodiment of a dental treatment unit according to the present invention.
In the figure, 1 is a dental treatment chair, 2 is a spittoon body, 3 is a bowl, 4 is a dental treatment table and an instrument holder for an operator, 5 is an instrument holder for an assistant, 6 is an instrument for dental treatment. , 7 is a base portion of the dental treatment chair 1, 8 is an arm that supports the instrument holder 5 for an assistant, and the arm 8 is attached so as to be movable in the arrow R direction around the support point P.

In the present invention, the arm 8 of the instrument holder 5 for an assistant is substantially at the center of the dental treatment chair 1 and the tilting / rotating portion of the backrest 1b (of the contour sheet portion 1a and the backrest portion 1b). It is mounted rotatably in a direction of an arrow R about a point P at a substantially lower portion of the connection portion), and in the vicinity of the rotation center P, a power supply line of the dental treatment table 4 for an operator, an air supply hose, and a water supply. A flexible cable 9 containing a hose or the like is connected, and the dental treatment work table 4 for the operator can be moved by a caster 10 or the like to a position where a doctor can easily use it.

FIG. 2 is a plan view of the dental treatment unit according to the present invention shown in FIG. 1 when viewed from above (however, the dental treatment work table 4 for the operator is omitted), which is a right-handed doctor. When treating, the assistant instrument holder 5 is rotated to the A position in FIG. 2, and when treating by a left-handed doctor, the assistant instrument holder 5 is rotated to the B position in FIG. Has been used.

Although FIG. 1 shows an example in which the dental treatment table 4 for the operator can be moved by using the flexible cable 9 and the casters 10, as shown in FIG.
The dental treatment table 4 for the operator is also constituted by an arm 11 like the arm 8 of the instrument holder 5 for assistant, and the rotation center thereof is the rotation center P of the arm 8 of the instrument holder 6 for assistant. You may make it rotate coaxially with. Although FIG. 3 shows an example in which the caster dental treatment table 4 is not provided with casters, of course, casters may be provided.

[0013]

As is apparent from the above description, according to the present invention, (1) the arm of the instrument holder for the assistant is rotated and the work table for the operator is simply moved to the left or right. Can be switched, (2) 4
An ideal assist position can be set for hand (doctor and assistant) treatment (the assistant holder arm extends from the base of the chair, so the assistant instrument holder is placed in a symmetrical position with respect to the head rest). If the assistant holder arm is out of the Spitton body as before, the arm will come to the assistant area and this position cannot be obtained.) (3) Depending on the height of the dental treatment chair, The height of the instrument holder does not change, and it is possible to assist at the same height position at any time. (4) The dental treatment table for the operator and the instrument holder for the assistant can be quickly changed position. Units can be provided and therefore Academic hospitals and, in the case or the like for public clinics, such as the use is more than one doctor, right-handed, left-handed doctor there is no problem even if the mix.
