Description

[Detailed explanation of the idea] Industrial applications This invention relates to a suction device for dental treatment.

Therefore, this invention can be used not only in dental treatment, but also in the dental treatment machine and instrument manufacturing industry.

BACKGROUND OF THE INVENTION Teeth polishing is often performed during dental treatment. At this time, it is necessary to cool down the heat of polishing and to remove fine tooth dust generated by polishing from the affected area. For this purpose, powerful water jets are used.

The above-mentioned jet water, fine tooth dust, and saliva secreted during treatment (sometimes also mixed with therapeutic drugs)
The mixture accumulates in the patient's throat, and as the patient tries not to swallow the mixture, he or she has difficulty breathing and experiences pain. To alleviate this patient's pain, the dentist or his assistant typically inserts a breathing tube into the oral cavity and suctions out the accumulated fluid. However, the state of accumulation of fluid in the oral cavity is
Since it is not clearly visible from outside the oral cavity, it is difficult to apply the suction port of the suction tube to the appropriate position, and the accumulated fluid is not removed properly. For this reason,
Dentists are unable to concentrate on treatment, which is a major obstacle in dental treatment.

Problems to be Solved by the Invention The purpose of this invention is to provide a suction device component for dental treatment that can easily and efficiently remove accumulated fluid that accumulates in the oral cavity during dental treatment.

Means for Solving the Problem This invention consists of a hollow body having a shape similar to a hollow elliptical hemisphere, a drainage pipe 2, and a breathing pipe 3, and the hollow body has a front side wall 11 and a rear side wall 12 connected to each other. A side wall is formed by surrounding the cavity 13, and the front side wall 11 and the rear side wall 12 have a large number of pores, and the breathing pipe 3 is fixed to the drain pipe 2, and the drainage pipe 2 is fixed to the drain pipe 2. The suction instrument for dental treatment is characterized in that the tube 2 passes through the side wall so that one end opens into the cavity 13, and the breathing tube 3 has both ends opening outside the cavity 13.

Next, the constituent elements of this invention will be explained in detail.

(breathing pipe and drainage pipe) The breathing tube 3 is fixed to the drain tube 2.

When the breathing tube 3 is fixed to the drain pipe 2, the breathing tube 3
may be located outside the drain pipe 2 (see Figures 5 and 6).
(see figure), a part of the breathing pipe 3 may be located inside the drain pipe 2 (see Figs. 2 and 3).

The breathing tube 3 may protrude forward of the front side wall 11 enough to prevent cooling water injected from the front of the front side wall 11 (outward direction of the oral cavity) from entering the breathing tube 3. desirable.

The side wall through which the drain pipe 2 passes may be the front side wall 11 or the rear side wall 12 (see FIGS. 3 and 8).

(Side Wall) The side wall is formed by combining the front side wall 11 and the rear side wall 12. The rear side wall 12 is desirably made of an elastic material such as elastic rubber, soft polyvinyl chloride, or soft polyethylene so that it can flexibly deform according to the shape of the oral cavity and not cause discomfort to the patient. The front side wall 11 is made of elastic rubber, for example.
It may be made of an elastic material such as soft polyvinyl chloride or soft polyethylene. For example, it may be made of metal, ceramic, or hard material such as hard polyethylene.

(Others) During dental treatment, the front side wall 11 and the back side are used to prevent cooling water sprayed from the front (outward direction of the oral cavity) from entering the deep part of the oral cavity through the gap between the side wall and the oral cavity. An annular water-intrusion prevention membrane 6 may be fixed at the boundary of the wall 12 (see FIGS. 9 and 10). The water intrusion prevention membrane 6 is preferably made of an elastic material such as elastic rubber, soft polyvinyl chloride, or soft polyethylene in order to flexibly deform according to the shape of the oral cavity and not cause discomfort to the patient.

Function During dental treatment, the suction device for dental treatment of this invention is inserted into the oral cavity with the front side wall 11 facing the front of the oral cavity (outward direction of the oral cavity) and the rear side wall 12 facing the back of the oral cavity. , When the drain pipe 2 is connected to a pipe such as a rubber pipe and suction is performed with a vacuum pump, the empty chamber 13
becomes depressurized. When the pressure in the cavity 13 is reduced, liquid and tooth polishing powder pass through the pores 5 and enter the cavity 13.
The liquid becomes foamy and is discharged to the outside through the drain pipe 2. The breathing tube 3 allows the patient to breathe comfortably through the mouth.

EXAMPLES Next, the breathing apparatus for dental treatment of this invention will be specifically explained using examples.
