BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing scattering of saliva or the like for dental treatment.

[0002]

2. Description of the Related Art When using Tabin in the oral cavity for the treatment of dental diseases, saliva and gums bleed and blood scatters out of the oral cavity, making it difficult to treat. If it is, there is a risk that bloody blood may infect doctors, hygienists, and assistants. Therefore, the actual situation is that the number of applicants for hygienists and assistants has decreased dramatically.

At present, as protective measures against the scattering of saliva and blood, there are glasses and face guards.

[0004]

[Problems to be Solved by the Invention] However, since the above-mentioned glasses and face guards are unpleasant when used, female hygienists and assistants are unwilling to use them, and these are not recommended. It may put more psychological pressure on the patient and may cause fear of dental treatment more than necessary, and may even refuse treatment, especially for infants.

The present invention has been made in view of the above-mentioned problems of the above-mentioned prior art, and is constituted so as to prevent the saliva and blood from scattering near the mouth of a patient, so that the scattering-preventing receiving plate is provided. Dental treatment that makes it difficult to enter the patient's field of view and allows dental treatment without giving anxiety or fear tubes to the patient, and that it is possible to perform saliva and blood suction operations and treatment without obstacles with a transparent support plate. It is an object of the present invention to provide a device for preventing saliva and the like from scattering.

[0006]

In order to achieve the above object, a saliva spatter preventive tool for dental treatment according to the present invention comprises a vacuum tube having a suction nozzle for saliva at its tip, It is characterized in that a transparent receiving plate for preventing saliva or the like provided with a receiving part for saliva or the like is attached to the upper part of the nozzle so as to be detachable and rotatably laterally.

[0007]

[Function] During dental treatment, when Tabin is used in the oral cavity, saliva and blood bleeding from the gingiva try to scatter from the inside of the oral cavity to the outside, but it collides with the transparent receiving plate provided in the vacuum tube. , Will not scatter to the hygienist or assistant side. That is, airborne scattering of saliva, blood, etc. is prevented.

The saliva and blood that hit the transparent receiving plate flow down along the receiving plate to the receiving portion provided at the base. Therefore, by connecting the receiving part to the vacuum tube with a hose, saliva and blood flowing down to the receiving part are guided to the vacuum tube through the hose and sucked by the vacuum tube. become.

On the other hand, saliva and blood in the oral cavity are sucked into the vacuum tube from the suction nozzle at the tip of the vacuum tube and discharged into a tank or the like to which the vacuum tube is connected.

Further, since the receiving plate is made of a transparent material,
The inside of the oral cavity can be seen through, and the suction operation and treatment of saliva and blood by the vacuum tube can be performed without any trouble. Furthermore, when there is no risk of saliva, blood, etc. being scattered, by avoiding the transparent support plate by rotating it laterally, the visual field inside the oral cavity can be widened and the visual field can be brightened.

When the transparent backing plate becomes dirty, it is removed and cleaned, or replaced with a new one.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a vertical sectional view in a use state. FIG. 2 shows a plan view.

As shown in FIGS. 1 and 2, the vacuum tube 1 is formed so as to be easily held, a suction nozzle 2 is provided at the tip bent downward, and a hose 3 is provided at the base end. Is connected to a vacuum pump (not shown). A holder 4 is fitted and fixed to the vacuum tube 1, and a main body 5 of the device for preventing the saliva, blood, etc. from scattering is freely attached to the holder 4 in a vertical direction and a horizontal direction by a ball joint 6 or the like. It is supported so that it can change its direction.

Since the main body 5 is supported on the upper portion of the vacuum tube 1, a fitting concave portion 8 of the receiving plate 7 is formed on the front portion of the main body 5 in a substantially U-shaped side surface. The base end 7a of the receiving plate 7 can be freely attached to and detached from the fitting recess 8, and the arrows a and a'in FIG.
It is rotatably fitted to the side indicated by.

On the upper portion of the main body 5, there is formed a finger insertion hole 9a for the thumb or the like in the upper portion so as to penetrate in the front-rear direction, and a support shaft 9b is vertically provided at the lower end of the operation plate 9, and a rear end connecting portion. The fulcrum 10 is used to open and close.

When the main body 5 and the operation plate 9 are formed separately, the rear ends of both are connected by a hinge (not shown), but when both are integrally formed of plastic,
As shown in the figure, the rear ends of both are continuously provided at the thin portion 10a.

Furthermore, on the front upper surface of the main body 5,
A shaft hole 11 is communicated with the fitting recess 8 and opened at a position corresponding to the support shaft 9b, and a shaft hole 12 is also formed in the base portion 7a of the receiving plate 7 corresponding to the shaft hole 11. It is formed through.

Therefore, with the base portion 7a of the receiving plate 7 fitted in the fitting concave portion 8 described above, the operation plate 9 is rotated counterclockwise in FIG. By closing the support shaft 9b into the shaft holes 11 and 12 of the main body 5 and the receiving plate base portion 7a by closing it upward, the receiving plate 7 can be attached to and detached from the main body 5, and the arrow in FIG. It is rotatably attached at a predetermined angle (about 90 degrees) to the side indicated by a and a '.

The receiving plate 7 is formed of a transparent plate made of plastic or the like that allows the inside of the suction nozzle 2 and the oral cavity of the patient A to be seen through and that can be easily deformed with only a fingertip. In addition, the receiving plate 7 is
The mouth B is formed to have a size large enough to cover it at a position separated by an appropriate size, and is formed so as to incline and rise forward from the base 7a. Blood is allowed to flow from the tip side to the base side.

Further, the receiving plate 7 is formed with a receiving portion 7b for saliva or the like in a lower portion near the base portion 7a so that saliva or the like adhering to the receiving plate 7 can be stored under flow.
The receiving portion 7b is connected to the vacuum tube 1 by a hose 13 so that saliva and the like in the receiving portion 7b is sucked into the vacuum tube 1.
