Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction device for suctioning liquid or the like discharged from a patient's mouth or cutting chips or the like generated when cutting dentures in dental treatment.

[0002]

2. Description of the Related Art A conventional suction apparatus for dental treatment will be described with reference to FIG. 3. Reference numeral 50 denotes a suction pipe, which is connected to a suction apparatus (not shown). A suction port (suction shield plate) 52 made of a conical transparent synthetic resin is connected to an end of the suction tube 50 via a flexible tube 51. Incidentally, 53
Is a guide body for the flexible tube 51. When treating the patient's teeth, the dentist 55 wears a mask or glasses, places the suction shield plate 52 at the mouth from the front of the patient, and treats the patient with the treatment tool 56 from the back of the patient's head. Do. At this time, cutting chips, blood, body fluid, and the like discharged from the patient's mouth are sucked into the suction shielding plate 52, and the flexible tube 5
1. It is sucked by the suction device through the suction tube 50.

[0003]

When a treatment is performed using a suction device of the type described above, cuttings, blood or body fluid discharged from the mouth of the patient are discharged at a high speed and sucked into the suction shield plate. Sometimes, blood and the like of a patient may adhere to a dentist's mask and the like. Therefore, it is not enough to deal with hospital-acquired infections, which have recently become a problem. Further, in dental treatment, it is necessary to perform a cutting process to correct dentures and the like, and to process the scattered cutting chips. Therefore, there is a demand for a suction device that can sufficiently exhibit suction ability and can be easily used for other purposes in preparation for such various cases.

[0004]

According to the present invention, a suction rotating body having an opening of a suction main body and a suction device connected through a suction tube and having a plurality of tension outlets is provided. Is rotatably attached to the suction main body 1 and a communication hole 3 is formed on the periphery of the suction main body so as to be able to communicate with any of the tension outlets, and a suction hood is attached to the tension outlet. Therefore, by rotating the suction rotating body 5, suction can be performed with a suction hood of another shape, and the suction hood can be easily used as a suction device for various purposes.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front sectional view of a suction device, and FIG. 2 is a diagram showing a use state of the suction device. The suction body 1 is formed in a cylindrical shape made of synthetic resin or the like, and has an opening 1a.
Is connected to a flexible suction tube 2 and can be suctioned by a suction device (not shown). On the circumference of the suction main body 1, a communication hole 3 is formed in an elongated shape over about 1/3 circumference (half a circumference or less), and a suction hood 10 (10a, 10a,
0b). A suction rotating body 5 having a pair of right and left tension outlets 6a and 6b is rotatably inserted into the suction main body 1, and a circumferential O-ring 4,
Seal through 4. A support 7 is stretched around the suction main body 1 around the circumference, and supports the suction rotating body 5.

A ball 8 to be pressed by an elastic body (coil spring) 7 is embedded in two places around the tension outlets 6a and 6b, and the suction hood 1 is pressed by the pressing force of the ball 8.
The suction hood 10 can be easily replaced with various suction hoods 10 suitable for the intended use. In the present embodiment,
As shown in FIG.
Is provided with a suction nozzle 10a which can be applied to the mouth, and a flapper hood 10b which can suction cutting chips when cutting dentures or the like is attached to one of the outlets 6b.

A liquid suction device 12 for sucking liquid or the like discharged from a patient's mouth is connected to the bottom of the suction main body 1 via a tube 13 via a cock 13. On the other hand, an L-shaped suction pipe 16 having a suction port 16a near the bottom is provided in the suction body 1 and connected to a liquid suction device (not shown) by a tube 17.

Next, a method of using the suction device having the above-described configuration will be described. FIG. 2 shows a state in which dental treatment is performed using a suction device. Since a suction device (not shown) is in operation, air or the like in the suction main body 1 is sucked. Also, since the suction nozzle 10a communicates with the suction main body 1, the tension outlet 6a
When the suction rotary body 5 is rotated so that the position of the suction rotary body 5 matches the position of the communication hole 3, the one outlet 6 b is closed with the communication hole 3. In this state, the spit, air, etc. in the mouth of the suction from the suction nozzle 10a can be sucked by the suction device through the stretch outlet 6a, the communication hole 3, and the suction body 1.

[0009] Saliva, tooth shavings and the like discharged from the patient during the treatment are sucked by the suction nozzle 10a and enter the suction main body 1. Light weight ones are sucked through the suction pipe 2, while heavy ones are sucked out. A spiral vortex is formed in the suction body 1 and accumulates at the bottom of the suction body 1. Then, by the activated liquid suction device,
The liquid or the like collected at the bottom is sucked from the suction port 16a via the suction pipe 16 and the tube 17. The dirt and the like accumulated in the patient's mouth are sucked into the suction body 1 by opening the cock 13 and sucked by the liquid suction device 12, and then sucked and exhausted in the manner described above.

Next, a description will be given of a case where the suction device is used not for treatment of a patient but for suction of cuttings such as dentures. By rotating the suction rotating body 5 to the position where the tension outlet 6b matches the communication hole 3, the hood 1
0b is allowed to be sucked, while the tension outlet 6a is closed.
Therefore, when a cutting action such as dentures is performed in front of the wrapper hood 10b, the cutting chips are sucked and conveyed via a suction device or a liquid suction device.

As described above, the suction device of the present invention can be suctioned by the suction hood 10 having a different purpose (shape) by a simple operation of rotating the suction rotation body 5. Further, since the suction hood 10 is of a fitting type through the pressing force of the ball 8, it can be easily replaced with suction hoods of various shapes.

[0012]

As described above, the suction device of the present invention can be suctioned with a suction hood having a different shape by rotating the suction rotary member, so that the suction device can be easily used for various purposes. can do.
