Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental extraoral vacuum device, and more particularly, to a dental extraoral vacuum device which is stored in a box when not in use. The present invention relates to a dental extraoral vacuum device that is not in the way.

[0002]

2. Description of the Related Art FIG. 3 is a view showing an example of a conventional dental treatment unit provided with a dental extraoral vacuum apparatus. As is well known, a dental unit 10 comprises a treatment chair 1, a work table 2, a spittoon 3, It comprises an operating light 4 and the like, and further has, for example, various control valves in a water supply / drainage box 5, and controls the opening and closing of the control valves so that, for example, vacuum (vacuum) suction of dirt excreted in the spitton 3 is performed. ing. 11
Is a suction port of a dental extra-oral vacuum device for sucking and discharging dust of tooth cutting powder generated by dental treatment, 12 is an arm mechanism for movably supporting the suction port 11, and 13 is a water supply / drain box for the arm mechanism 12 5, the end of an exhaust duct 14 extending below the mounting member 13 is guided to a piping box 15 disposed under the floor or the like.
In 5, the solenoid valve is connected to an on / off controlled electromagnetic valve, and is guided to a vacuum pump (not shown) via the electromagnetic valve.

[0003]

Generally, the intake port 11 is used by being positioned near the oral cavity of a patient when the treatment chair 1 is moved to a treatment position (sleeping position).
Normally (when not in use), the patient is evacuated to a position where the patient does not get in and out of the treatment chair 1. However, even if the patient is evacuated to a position where the patient does not get in and out of the treatment chair 1, This time, there was a problem that the operation of the doctor (doctor) and the assistant could be disturbed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been made in order to prevent a dental extraoral vacuum apparatus from hindering the operation of a doctor or an assistant when not in use. It is.

[0005]

According to the first aspect of the present invention, there is provided an inhaler which is movably disposed in the vicinity of a patient's mouth and sucks and exhausts waste liquid, bacteria, cutting powder and the like scattered from the patient's mouth. In a dental treatment unit including a dental extraoral vacuum apparatus having a mouth, a storage box for accommodating the extraoral vacuum apparatus, the extraoral vacuum apparatus includes:
It is normally stored in the box and pulled out and used only at the time of use.

According to a second aspect of the present invention, in the first aspect of the present invention, the extraoral vacuum device storage box is a water supply / drainage control box to which spittons are integrally attached.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic diagram showing a main part of an embodiment of a dental extraoral vacuum apparatus according to the present invention. In FIG. 1, reference numeral 20 denotes an extraoral vacuum apparatus; FIG. 1A shows a storage box for storing the outer vacuum device 20. FIG.
FIG. 7 is a diagram showing a state when the storage unit 0 is stored in the storage box 30;
FIG. 1 (B) shows that the extraoral vacuum device 20 is in use.
Is drawn out of the storage box 30. The storage of the extraoral vacuum device 20 in the storage box 30 and the withdrawal from the storage box 30 may be manual, electric, or hydraulic, but a manual type is shown in the figure. . FIG. 1 shows an example in which the extra-oral vacuum device 20 is entirely stored in the storage box 30.

The extraoral vacuum device 20 has an air inlet 21 like the above-mentioned conventional extraoral vacuum device, and the air inlet 21 extends and contracts telescopically through a flexible tube 22, for example, a telescopic tube portion. 23, the telescopic tube portion 23 is connected to a piping box as described above, and in the piping box, connected to a solenoid valve that is controlled to be turned on and off, and guided to a vacuum pump via the solenoid valve. I have. Reference numeral 31 denotes a lid member provided in the storage box 30, and the lid member 31 is opened and closed when the extraoral vacuum device 20 is taken in and out, but is not always necessary.

FIG. 2 is a view showing an example of an arrangement of a main part of a dental treatment unit when a water supply / distribution box 5 having a spitton 3 is used as an extraoral vacuum device storage box 30. As shown in FIG. According to this, the extra-oral vacuum device 20 is stored in the water supply and distribution box 30 when not in use, so that the extra-oral vacuum device 20 does not hinder the work of the doctor or the assistant. In addition, in FIG. 2, 40 is a doctor's chair,
50 is an instrument holder for assistants, 60
Indicates a monitor, and 70 indicates an operating light arm.

[0010]

As is apparent from the above description, according to the present invention, when the extra-oral vacuum device is not used in the dental extra-oral vacuum device, the extra-oral vacuum device is connected to a dental unit, preferably a dental unit. Since it can be stored in the water supply / drainage box of the spitton (it can be made compact even if it is not completely stored), the extraoral vacuum device can be prevented from hindering the work of the doctor or assistant.
