2. Description of the Related Art Dental care rooms have a large number of outpatients,
If care is taken to effectively sterilize and disinfect the room, a large number of microorganisms may remain on the floor, on the surfaces of instruments and instruments, or in the air, etc. From the surgeon to the surgeon or from the surgeon to the patient. On the other hand, since various microorganisms inhabit the human oral cavity, there is a danger that secondary infection by the oral microorganisms may occur due to dental treatment, and in recent years, hospital infections caused by Staphylococcus aureus have occurred. Infection is gaining attention. Therefore, in dental treatment, it has recently been proposed to use a vacuum device to protect the surgeon from floating dust and bacteria, and to catch floating dust and bacteria leaking from the patient's mouth to the outside during medical treatment at the patient's mouth. ing.

FIG. 2 is a view for explaining an example of a dental treatment unit to which the extraoral vacuum apparatus proposed by the present applicant has been applied. In the figure, reference numeral 1 denotes a treatment chair, 2 denotes a work table, and 3 denotes a work table. Is a spitton, 4 is an arm for an operating light (not shown), 5 is a box for water supply and drainage, which has various control valves in the water supply and drainage box 5, and opens and closes the control valve. Vacuum (vacuum) suction of dirt discharged to the spitton 3 is performed. Also, 11 is an intake port, 1
Reference numeral 2 denotes an exhaust pipe (duct) connected to the intake port 11, and reference numeral 13 denotes a mounting member for rotatably mounting the arm mechanism 12 to the water supply / drain box 5, and an end of an exhaust duct 14 extending below the mounting member 13. The section is guided to a piping box 10 and the like disposed under the floor, etc., connected to a solenoid valve that is controlled to be turned on and off in the piping box, and guided to a vacuum pump (not shown) via the solenoid valve. I have.

[0004] The intake port 11 is generally used by being positioned near the mouth of a patient when the treatment chair 1 is moved to a treatment position (sleeping position). It is evacuated to a position where it does not get in the way when getting on or off the. In order to raise and lower the treatment chair 1, the memory switch is pressed to raise and lower the treatment chair 1 to a predetermined position. However, the air inlet 11 may be similarly moved to a predetermined position. However, if a dedicated memory switch is provided for moving the intake port 11 to move the intake port 11, the number of operations for that purpose will increase, and the efficiency of the treatment operation will be impaired.

Therefore, the movement of the air inlet 11 is controlled by the treatment chair 1.
It is moved in association with the movement of. That is, in order to move the treatment chair 1 to the treatment position, the memory switch is pressed, and when the treatment chair 1 falls to the predetermined position, the intake port 11 automatically moves following the end of the movement of the treatment chair 1. It starts, moves to a predetermined position near the patient's mouth, and stops. The determination of the predetermined position in this case is performed at the same time when the tilting position of the treatment chair 1 is determined. For example, the treatment chair 1 and the intake port 11 are adjusted to the predetermined positions according to the height, body shape, etc. of the patient, and the state is determined. When the memory setting switch is pressed, the positions of the treatment chair 1 and the intake port 11 in the inverted position are stored. Thereafter, when the inverted memory switch for the treatment chair 1 is pressed, the inhalation is performed following the operation of tilting the treatment chair 1. The mouth 11 is moved to a desired position near the patient's mouth.

When the treatment chair 1 is set at the starting position (gargle position), the starting position of the treatment chair 1 and the position of the air inlet 11 are set in the same manner. Is pressed, the intake port 11 is first moved to a desired starting position, and then the treatment chair 1 is raised. Reference numerals 15 and 16 denote piston cylinders provided with an inlet 11 at the joint of the support arm 12. By operating these piston cylinders 15 and 16, the arms supporting the exhaust pipe 12 or the flexible tube described above are indicated by arrows. It is moved in the directions A and B, whereby the intake port 11 can be moved to a desired position in conjunction with the movement of the treatment chair 1. In order to store the position of the intake port 11, the piston / cylinder 15,
The movement positions of the 16 pistons may be stored, and by storing and setting the positions, the pistons can be automatically moved to this position thereafter.

[0007] Basically, the intake port 11 may be moved between two positions according to the tilting of the treatment chair 1. However, when the operator performs processing, adjustment, or the like of the denture, the operator needs to draw the intake port 11 close to him. I want to use. Therefore, the exhaust pipe 12 is attached to the support member 13 so as to be rotatable in the direction of arrow C, whereby the exhaust pipe 12 can be drawn to the surgeon's hand by a manual operation. Is returned to the vicinity of the patient's mouth again by manual operation. In this case or in other cases, the user may want to adjust the direction of the intake port 11 to a desired direction. In consideration of such a case, the attachment portion 12a of the intake port 11 is made of a flexible tube or the like. The flexible tube 12a so as to direct the intake port 11 in a desired direction,
The intake port 11 may be attached to the tip of an arm mechanism (also serving as an intake duct) 12 using a universal joint. After the suction port 11 is positioned near the patient's mouth as described above, the suction / exhaust operation is started, and the suction air is suctioned / discharged with the contaminated air mixed with the sewage liquid, cutting powder and the like scattered during the treatment. This suction / discharge operation is performed in the piping box 2
This is performed by turning on and off the solenoid valve within 0.

[0008]

However, the above-mentioned dental extraoral vacuum apparatus operates as intended with respect to moving the inhalation port to the vicinity of the patient's oral cavity. In many cases, starting and stopping are performed by manual operation.
If stopped, the operator's hand repeatedly touches this switch, which is unsanitary. The present invention has been made in view of the above-described circumstances, and automatically activates and stops an extraoral vacuum device, so that an operator does not need to touch an operation switch or the like for starting or stopping. Thus, it is intended to provide a more hygienic dental treatment unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS When a surgeon pulls out a dental treatment instrument from an instrument holder, the dental extraoral vacuum device is automatically driven.

FIG. 1 is a view for explaining an embodiment of a dental treatment unit provided with a vacuum apparatus according to the present invention. In the drawing, reference numeral 21 denotes an intake port 11 or an object provided near the intake port 11. The detection sensor 22 is a switch that operates by tilting the arm or the exhaust pipe 12 that supports the intake port 11 or a sensor that detects the tilt of the arm or the exhaust pipe 12, and is similar to the dental unit shown in FIG. The parts that operate are given the same reference numbers as in FIG.

Thus, in the present invention, as described above, the sensor 21 is provided at the intake port 11 or near the intake port 11, and the sensor 21 causes the intake port 11 to approach the vicinity of the oral cavity of the patient. Or that it has moved away, and, by the detection signal, drives the vacuum device,
Alternatively, it is designed to stop. That is, in FIG. 1, when the intake port 11 is at the solid line position I, the vacuum device is operating, and when it is at the dotted line position, it is stopped. As the sensor 21, a known non-contact type sensor such as a reflection type ultrasonic sensor, an infrared sensor, or a temperature sensor for detecting a patient's body temperature is used.

In FIG. 1, reference numeral 22 denotes an exhaust pipe which activates the vacuum device when the arm supporting the exhaust pipe 12 is at a predetermined angle or less, that is, when the arm is at a position I indicated by a solid line in FIG. A switch (eg, a reed switch) or a sensor (eg, an optical sensor or a magnetic sensor) is stopped when it is in the dotted line position II. In the vicinity of the mouth can be accurately detected.

In the dental treatment, various instruments such as a micro engine, an air turbine, a scaler, and a syringe are used. These instruments are usually stored in an instrument holder. At the time of dental treatment, it is pulled out from the instrument holder and used. Therefore, when these instruments are pulled out of the instrument holder, the extraoral vacuum device is activated (the solenoid valve in the piping box 10 is turned on), and when the instruments are returned to the instrument holder,
The operation may be stopped (the electromagnetic valve is turned off). In this case, of course, a sensor for detecting the presence / absence of each instrument or a switch for turning on / off depending on the presence / absence of the instrument is provided in the instrument holder. The vacuum device is started and stopped by a sensor or a switch.

[0015]

As is apparent from the above description, according to the present invention, the dental extraoral vacuum apparatus can be operated and stopped without any trouble of the operator, and the dental treatment can be performed more efficiently. Treatment can be given. In addition, since the operator does not need anything that the operator touches, for example, a manual switch, to operate and stop the vacuum device, more hygienic dental treatment can be performed.
