DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical and dental chair unit, and more particularly to a medical and dental unit having an auxiliary tray table in an instrument holder on an assistant side.

[0002]

2. Description of the Related Art Conventionally, a drawer-shaped tray having a deep recess which can be pulled out or stored together with an instrument behind an instrument holder on the assistant side of a medical / dental chair unit. In addition, a small table was attached to the rear of the instrument holder, but none of them could be easily attached and detached. On the tray or the small table, the examination instrument is placed on the surface thereof, or a portable tray on which the examination device is set is placed, or the operation such as mixing of therapeutic drugs is performed on the surface. Had been Therefore, cleaning and disinfection when the tray or the small table is contaminated is troublesome, and further, when the inspection device or the portable tray on which the inspection device is set is placed on the surface, an instrument holder is required. The position of the appliance may be shifted due to vibrations when the robot is moved or contact with an assistant, and there is a problem in stability.

[0003]

(1) A medical and dental chair unit including a chair, a bracket table, and the like, comprising: an instrument holder on an assistant side; and an auxiliary tray table detachably disposed adjacent to the instrument holder. A medical and dental chair unit wherein a permanent magnet is fixed on a bottom surface of an auxiliary tray table in a planar manner. (2) The medical and dental chair unit according to (1), wherein the auxiliary tray table is made of a non-magnetic material. (3) The medical and dental chair unit according to (1), wherein the auxiliary tray table is made of a magnetic material. (4) The medical device according to any one of (1) to (3), wherein the permanent magnet on the bottom surface of the auxiliary tray table and the entire auxiliary tray table are covered with a non-magnetic thin film. Dental chair unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, with the structure and operation of the embodiments being taken as examples. FIG. 1 is an external perspective view of an auxiliary tray table adjacent to an instrument holder on the assistant side. In the figure, 1 is an auxiliary tray table (tray-shaped small table), 8 is an operation keyboard, 9 is an instrument holder and a rotating arm for taking in and out an auxiliary tray table, 1
0 is a chair unit, 11 is an instrument holder, 12 is a bracket table, 13 is a gargle, 14
Is a chair, 15 is an overarm, 16 is a foot switch, 27 is an instrument holder and an auxiliary tray table. FIG. 2 is a detailed view of the auxiliary tray table. FIG. 2 (A) is a plan view of the auxiliary tray table, and FIG. 2 (B) is a sectional view of FIG. In the figure, 2 is an auxiliary tray table chassis, 3 is an upper surface cover, 4 is a magnet, 5 is a support, 6 is an auxiliary tray table attaching / detaching plate, 7 is a leaf spring, 26 is an insertion or pulling-out direction,
It is. The auxiliary tray table 1 is inserted behind the instrument holder 11 by an auxiliary tray table attaching / detaching plate 6 at the base of the auxiliary tray table. As shown in the figure, the auxiliary tray table 1 has an auxiliary tray table attaching / detaching plate 6 fixed to the bottom surface of the chassis 2 of the auxiliary tray table by a support tool 5 under the leaf spring 7 at the bottom of the instrument holder 11. By inserting or pulling out in the direction of arrow 26, it can be easily attached and detached. A flat magnet 4 (for example, a plastic magnet) is attached to the upper part of the chassis 2 of the auxiliary tray table 1, and the upper surface thereof is further covered by a nonmagnetic upper cover 3.

FIG. 3 is an external view showing a portable examination instrument tray and examination instrument placed on an auxiliary tray. In the figure, 17 is a portable examination instrument tray, 18 is a mirror, 19 is tweezers, 20 to 22 are spoon extractors, and 23 is a dental probe. In general, the material of the portable medical examination instrument tray 17 is often made of stainless steel (austenitic: soft viscous, large anti-corrosion, suitable for containers, etc., non-magnetic material) in accordance with the application. Stainless steel (martensant type: high hardness, magnetic material suitable for cutting tools, instruments, etc.).

FIG. 4 is a cross-sectional view when the portable examination instrument tray 17 and the examination instrument (22) are placed on the auxiliary tray table 1. As shown in the figure, the spoon extractor 22 (magnetic material) of the examination tool is a magnetic field line of the magnet 4 of the auxiliary tray table 1 passing through the bottom surface of the portable examination instrument tray 17 (non-magnetic material). As a result, the position is stabilized because it is sucked in the suction direction 24.
Further, since the other examination instruments are also magnetic materials, the position of the portable examination instrument tray 17 on which the examination instruments are placed is also stabilized. Therefore, it is possible to prevent the placement instrument from moving due to vibration or the like. The above is an example in which the portable examination instrument tray 17 is used. However, even if the examination instrument is placed directly on the tray table 1, the above-mentioned suction action is the same. When the auxiliary tray table 1 is to be cleaned and disinfected, the auxiliary tray table attaching / detaching plate 6 can be detached to facilitate the cleaning.

[0007]

According to the present invention, the following effects are exhibited. Cleaning and disinfection when the auxiliary tray table provided on the assistant side is contaminated can be easily performed,
In addition, when the inspection instrument is placed, the instrument is stabilized by the attractive force of the magnet, so that it is possible to prevent the vibration of the instrument holder from moving and the displacement of the instrument due to the contact with the assistant. it can. The auxiliary tray table may be magnetic or non-magnetic, and the permanent magnet on the flat plate disposed on the bottom surface may be simply placed when the auxiliary tray table is magnetic, and When the tray table is a non-magnetic material, it is fixed on the bottom surface. Further, the magnet and the entire auxiliary tray table may be covered and fixed with a non-magnetic material. Therefore, medical care work in medical dentistry can be performed smoothly, which contributes to work efficiency.
