Description

[Detailed description of the invention] (Scope of industrial use) This invention is a suction device for drainage, etc. that automatically suctions and disposes of wastewater accumulated in the oral cavity of a dental treatment patient to the outside. It is related to.

(Conventional technology) In normal dental treatment, when preparing upper molar teeth, a dentist (hereinafter referred to as an operator)
The tooth is ground down using a grinder, and cooling water is poured into the patient's oral cavity during this grinding to protect the tooth pulp and tooth supporting tissue.

The water injected into the oral cavity is mixed with cuttings, patient's saliva, etc., and then becomes waste water.

This wastewater is sucked into the vacuum suction port placed in the cooling water discharge direction, and most of it is automatically discharged to the outside. The current situation is that they are excluded.

By the way, wastewater that is not sucked into the vacuum suction port and remains in the oral cavity accumulates in a low place in the oral cavity (called a retention spot), and in order to dispose of this, the surgeon takes a break from time to time and then calls the assistant. The position of the vacuum suction port was temporarily moved to the storage spot, thereby draining the water stored in the cavity.

(Problems that the invention aims to solve) However, such conventional wastewater treatment methods require an entire assistant in addition to the operator, and the above method also ensures that the vacuum suction port does not reach the oral cavity. Since it is not fixed, it is difficult to avoid an increase in the amount of stored water, which has the problem of hindering treatment efficiency.

Therefore, the present invention has developed a drainage system that allows the operator to easily prepare the patient's mouth with the patient's mouth open without the assistance of an assistant, and to suction the wastewater efficiently. The purpose is to provide a suction device for

(Means for solving the problem) In order to achieve the purpose, the structure of the suction device for drainage, etc. of the present invention has a shape in which a rectangular plate is bent into a substantially V shape as a whole. An occlusal part 5a, which has an insertion hole penetrating in the front-rear direction at the center of the bend, and whose upper and lower outer opposing ends are sandwiched between the upper and lower teeth of a dental treatment patient;
an opening holder 2 formed into a shape 5a, and a small tube 3 which is slidably inserted and held in the insertion hole, the tip of which is continuous with the saliva ejector 3 in the axial direction. It is characterized in that it is formed into a suction nozzle 8 having a small suction hole, and its base end is formed by a saliva ejection tube 3 connected to a vacuum suction hose.

(Function) Due to the structure of such a suction tool for drainage, etc., the insertion position of the saliva ejector, which has a drainage suction nozzle at the tip, is securely fixed and held by the patient's occlusion with the patient's teeth. In addition to ensuring that the insertion position remains at the reservoir spot, aligning and adjusting the position of the suction nozzle with the reservoir spot requires a simple one-touch operation, thus eliminating the need for any assistance from an assistant. Moreover, since the suction side of the saliva ejector is connected to the vacuum suction hose,
Provides strong drainage power.

(Example) Hereinafter, the structure of the present invention will be specifically described based on the example shown in FIGS. 1 to 8.

First Embodiment (See FIGS. 1 to 6) A suction device 1 for draining water, etc. of this embodiment includes an opening holder 2 and a saliva ejecting tube 3 that are integrally molded. First, the opening holder 2 has a substantially V-shaped arm 5;
A boss tube 6 that extends outward on the axis of the arm 5
and an interlocking portion 5a formed at the upper and lower opposite ends of the arm 5. This occlusal part 5
A may be formed to have a U-shaped cross section at the opposite end of the arm 5, and an uneven portion 5b may be formed on the intermediate outer surface as shown in FIG.

Next, the saliva ejecting tube 3 has a tube 7 as its main body, and a suction nozzle 8 is formed at the tip of the tube 7, and a stopper 9 is provided on the outer peripheral surface of the tube 7 near the nozzle 8. It is bulged and has the function of regulating the sliding position of the tube 7.

Furthermore, a metal wire 4 is embedded in the tube wall along the inner hole of the saliva ejecting tube 3 along the linear direction of the tube 7 in order to give the tube 7 appropriate flexibility.

Next, when the suction tool 1 for drainage, etc. of the embodiment configured as described above is used, as shown in FIG. It is connected to the intermediate hose 11 of the system.

Next, this suction tool 1 is inserted into the oral cavity M of the patient P, and its occlusal part 5a is brought into contact with each of the upper and lower molars T of the patient. Close it halfway until it hits.

In this way, the suction nozzle 8 can be reliably and firmly fixed and held at the required storage spot position, allowing the operator to perform treatment efficiently.

In addition, as shown in FIG. 7, the occlusal part 5a and the molar tooth T
Absorbent cotton 14 may be interposed between them, or the occlusal portion 5a and the molar tooth T may be bonded together using an instant polymerization range adhesive.

Here, the suction device 1 for drainage, etc. of the embodiment is used as described above, but when the operator performs reduction treatment on the molars of the upper jaw, in most cases, the suction tool 1 for draining, etc. Since the center of the diagonal line within the right mandibular ramus is the storage spot position, the patient's mouth is kept open during treatment.
Drainage water during treatment is automatically vacuumed to the outside and removed.

In addition, when preparing the upper right molar teeth, the suction device 1 for drainage, etc. is interposed on the occlusal surfaces of the upper and lower left molars, but at this time, the patient's head tilt is the same as in the previous section. leaning slightly to the right.

Therefore, the patient's head should be tilted to the left from time to time to allow drainage, etc. to be suctioned out.

As described above, with the suction device 1 of the embodiment, the operator can perform preparation without using an assistant by simply putting in the slight effort of setting the suction device, and also, Since the treatment of wastewater etc. during treatment is carried out automatically and powerfully,
Treatment time is shortened and patients are more comfortable.

Note that this suction tool 1 can also be applied to the preparation of mandibular molars and other teeth.

(Effects of the invention) As described above, according to the suction device for drainage, etc. according to the present invention, the opening holder 2 is held between the teeth of a patient to be treated, and the saliva ejector 3 is inserted through the holder.
By configuring the suction device according to This has the effect of improving performance and efficiency.

Further, according to the present invention, the opening holder 2 has a shape in which a rectangular plate is bent into a substantially V shape, and is slidably inserted into the insertion hole at the center of the bend. Suction nozzle 8 at the tip of the saliva ejector 3 held
Since it is formed into a small cylindrical shape that is continuous with the saliva ejector 3 and has a small suction hole, it is simple and gives less foreign body sensation to the patient, and does not interfere with treatment.

The saliva ejection tube 3 is slidably inserted and held in the insertion hole provided at the center of the bend of the opening holder 2, so that the small cylindrical suction nozzle 8 at the tip thereof
It can be easily set in a drainage spot in a patient's mouth to forcefully and effectively drain water.

Furthermore, in the present invention, the saliva ejector 3 and the suction nozzle 8 at its tip are on the same side as the opening holder 2, that is, if the opening holder 2 is on the left side of the patient's mouth, the saliva ejector 3 is also on the left side. Because of its location, there is little foreign body sensation to the patient.
