Description

DETAILED DESCRIPTION OF THE INVENTION The present application discloses that, in the process of transitioning from a non-treatment position in which the backrest of a treatment chair is upright to a treatment position in which it lies down, for example, a surgical light arm treatment table, a treatment instrument holder, etc. After guiding the therapeutic working mechanism to the operating position most suitable for the therapeutic work, one of the therapeutic working mechanisms is moved away from the operating position t so as to turn on the surgical light, drive the therapeutic equipment, or operate the water supply mechanism. When the chair is moved to the non-operating position, the operating light is turned off or the treatment equipment is in a non-operating state, so that the light beam from the operating light does not stimulate all of the patient's eyes during the raising and lowering movement of the treatment chair. The present invention relates to a dental treatment device whose entire purpose is to prevent the risk of the treatment instrument being accidentally driven and the necessary water supply being performed due to injury, so that the treatment work can be carried out safely. It is something.

All the drawings of the example of a serious crime will be explained in detail below.

In a conventional treatment chair, the lifting and lowering of the seat, the raising and lowering of the backrest, and the tilting of the seat (tWI) as needed are performed via an operation control circuit using an automatic operation switch and a manual operation switch. A dental treatment chair that can be automatically and manually moved by η between the treatment position and the oil-free position is disclosed in, for example, Japanese Patent Publication No. 53-41477, No. 53-41478, and Japanese Patent Publication No. 53-41478. 54-30233
It is publicly known in the publication No. 1, and A in Fig. 1 is a treatment chair configured with this construction. It shows. B is a support part (2) provided integrally with the base (1) of the treatment chair A.
An operating light mechanism mounted on the upper end of an upright column (31), for example, a drive unit consisting of a fluid placement unit and an IJ.

Figure 2 is a block diagram of the operating circuit showing the operational relationship between the treatment chair A, the operating light mechanism B, and the operating light (51). 1
is the operation switch for guiding the treatment chair A to the non-oil abutment, and to each operation switch, the treatment chair A is connected to the operation control circuit (121° (13m)) to set the treatment position. The movement between the non-treatment position and the non-treatment position is the same as that of the known dental treatment chair mentioned earlier. The first operation control circuit O2 fully controls the drive section (4) so that the operation position is set at the operation position! (the position indicated by the solid line in Figure 1).
The third operation control circuit that operates in response to the operation stop signal a of Totame et al. The actuation signal b&cjpf''I of the second actuation control circuit (137/'' et al.

This is a fifth operation control circuit that stops the lighting of the operating light (51) when the IJ set signal dK↓ is applied.

Therefore, during treatment, when the patient operates the setting operation switch 0I while seated on the treatment chair, the treatment chair A moves to the treatment position via the O1 operation control circuit Oa. Then, when the treatment chair A reaches the treatment position, the operating light mechanism B is moved to the inoperative position via the third operation control circuit (141) which generates an operation stop signal aK↓ of the driver's first operation control circuit Q21 and vh. η moves to the operating position, and when it reaches the operating position, the operation stop signal C of the third operation control circuit IJ41.c generated from the third operation control circuit α is the fifth operation control. By inputting this signal, the power supply (161) is energized and the operating light (51
lights up.

Next, when the treatment work is completed, the 1 noset operation switch (til't-operate). Then, the treatment chair A moves to the non-treatment position via the second operation control circuit 1 (131), and the second The fourth operation control circuit t151 receives the operation signals blC and C from the operation control circuit (131), and the operating light mechanism B starts moving to the inoperative position with all valves turned on. The fifth actuation control circuit is turned OFF by the reset signal dK, the electricity is cut off, the operating light (5+) is turned off, and after that, the treatment chair A is

A fourth operation control circuit (19) is actuated by the reset operation switch dll that controls the drive unit (41) so as to restore the drive unit (41) to the position indicated by the virtual line.
and the operation stop signal e from the operation control circuit a21.
and an operation stop signal f from the third operation control circuit 181.
By each input, the operating light (51) is allowed to turn on, and the operation start signal gK↓ of the fourth operating control circuit a is turned on, and the fifth operation completely stops the lighting of the operating light (5+). It is a control circuit.

When performing treatment, press the set operation switch (1 (l) with the patient seated on the treatment chair.
The treatment chair A moves to the treatment position via the O1 operation control circuit (121), and the surgical light mechanism B moves to the operation position via the third operation control circuit Q1.

Then, when the treatment chair A reaches the treatment position and the sword and surgical light mechanism B reach the operating position, the fang [and the three operation control circuits]
The operation stop signal elf from 121 and Q81 is input to the fifth operation control circuit ■, and the input of these signals causes the source (16
1 is energized and the operating light (51) lights up.

Next, when the treatment work is finished, operate the reset operation switch (tll').Then, the treatment chair A will switch to the second position.
When the operating light mechanism B enters the non-treatment state via the operation control circuit α&, the operating light mechanism B starts moving to the non-operation position via the fourth operation control circuit (lFt-), and the operation of the fourth operation control circuit at that time Operation start signal (11 set signal)gKEL 5th operation control circuit Cυ is turned OFF and power is cut off, operating light +5
1 goes out, after which the treatment chair A returns to its non-treatment position and the surgical light mechanism B returns to its inoperative position.

Although the above example uses the surgical light machine #I as the treatment working mechanism and the surgical lamp as the working member, Tsukuda also uses a treatment device as shown in, for example, Japanese Utility Model Application No. 56-113526. Even if the treatment instrument hanger is configured to be movable via a guide shaft on the side of the back of the chair between the lower position, which is the inactive position, and the upper position, which is the activated position. As a power source, a treatment instrument such as an air turbine handpiece is used, and as a power source, a pressurized air source or the like is used as a power source.

Based on the above, according to the present application, when the treatment chair moves to the treatment position and the treatment work mechanism also reaches the operating position most suitable for the treatment work, the work members are fully allowed to operate, and the treatment chair is in the non-operative position. In the treatment position, the treatment work mechanism is configured to stop the operation of the work members when the treatment is moved to the IU and the kJJ meeting starts, so for example, if the back of the treatment chair is in a prone position or
There is no longer any risk that the operating light will stimulate the patient's recording during the process of transitioning from the patient's position to the standing position, or that the treatment instrument will accidentally activate and cause injury, or that the water supply mechanism will operate unnecessarily. A safe treatment operation can be carried out, and the operation of moving the treatment working mechanism between the inoperative position and the working position and the movement of the working member each time the movement is performed.

It is also possible to omit the conventional troublesome work of manually performing the stop switching operation, and there is no malfunction, making this invention extremely useful for dental treatment work.
