Abstract

PROBLEM TO BE SOLVED: To judge whether suction-exhaustion operation is properly performed or not by providing an indicator displaying the vacuum suction force in an exhaust pipe to the outside of the exhaust pipe. SOLUTION: An exhaust pipe (flexible tube) 6 is attached so as to be guided into a water supply/drain box 4 by an attaching member 12 having an arm 11 integrally provided thereto. The indicator 20 obserbing the suction force (exhaustion quantity) in the exhaust pipe 6 is provided to monitor whether clogging is generated in an exhaust pipe route. The indicator 20 is constituted so that a piston 22 is provided in a transparent cylinder 21 and the spring 23 transferring the piston 22 to one end in the cylinder 21 and the cylinder 21 is allowed to communicate with the exhaust pipe 6 on the side where the spring 23 is arranged. By this constitution, it can be judged whether suction- exhaustion operation is certainly performed or not and, when exhaustion is not sufficiently performed, a vacuum pump is stopped to inspect an exhaustion pipe route to prevent the burn-off of the vacuum pump.

2. Description of the Related Art In a dental treatment room, many outpatients come and go,
If care is not taken to effectively sterilize the room, a large number of microorganisms may remain on the floor and on the surface of instruments and appliances, or in the air. From the operator to the operator, or from the operator to the patient, may become a place to transmit the pathogenic microorganism. On the other hand, since various miscellaneous microorganisms inhabit the oral cavity of humans, there is a risk of secondary infection due to oral resident microorganisms triggered by dental treatment. Recently, in the hospital due to Staphylococcus aureus Infection is attracting attention. Therefore, in dental treatment, it has recently been proposed to use a vacuum device to protect the operator from airborne dust and bacteria, and to catch airborne dust and bacteria that leak from the patient's oral cavity to the outside during medical treatment. ing.

FIG. 2 is a view for explaining an example of a vacuum device incorporated in a dental treatment unit. As is well known, the dental unit 10 comprises a treatment chair 1, a work table 2, a spittoon 3 and the like. Further, for example, various control valves are provided in the water supply / drainage box 4, and the control valves are controlled to be opened / closed so that, for example, filth excreted in the spittoon 3 is vacuumed (vacuum).

The dental unit 10 further includes an intake port 5, an exhaust pipe 6 for exhausting the contaminated air sucked from the intake port 5, a mounting member 7 for rotatably mounting the exhaust pipe 6, and Has an exhaust duct 8 extending below the attachment member 7, and guides an end portion of the exhaust duct 8 to a piping box 9 or the like arranged under the floor or the like.
Inside, it is connected to an on / off controlled solenoid valve, and is connected to a vacuum pump (not shown) via the solenoid valve.

In the dental treatment, the treatment chair 1 is controlled to a treatment position (tilt or sleep position) and a gargling position (starting position), and the tilting position and starting position are set and stored in accordance with the height of the patient. Memory), and thereafter, every time the memory (and auto) switch is pressed, it is automatically controlled to the set inclining position and starting position.
Is also moved to the vicinity of the patient's oral cavity, and dust such as cutting powder generated by dental treatment is sucked and discharged. When the treatment chair 1 is returned to the starting position, the intake port 5 is first moved to a predetermined position (a position where it does not hit the patient).

[0006]

In the dental extraoral vacuum device as described above, due to some cause,
Exhaust pipe system (system from intake port to vacuum pump)
If there is clogging in the inside, the vacuum pump is in full operation, but intake from the intake port 5 is rarely performed, and not only does the desired suction / exhaust action not be achieved. However, there was a problem that the vacuum pump burned out.

[0007]

According to a first aspect of the present invention, there is provided an intake port movably arranged in the vicinity of the oral cavity of a patient and an exhaust pipe movably supporting the intake port during dental treatment. In the dental extraoral vacuum device that moves the intake port to the vicinity of the patient's oral cavity, scatters from the patient's oral cavity during treatment, and sucks and exhausts dust and the like floating near the patient's oral cavity, An indicator for displaying the vacuum suction force inside the exhaust pipe is provided outside the pipe so that whether or not suction and exhaust are appropriately performed can be known.

According to a second aspect of the present invention, in the first aspect of the present invention, the indicator comprises a transparent cylinder, a piston arranged in the cylinder, and the piston biased to one end of the cylinder. And a spring for arranging the cylinder, and the side of the cylinder on which the spring is disposed communicates with the exhaust pipe, so that it is easier to determine whether or not the exhaust pipe 10 is appropriately exhausted. It was done so.
