Description

DENTAL SUCTION MIRROR

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a dental suction mirror and, more

particularly, to a dental suction mirror which is to efficiently suck blood, saliva,

cleaning water and antiseptic solution as well as sucked scraps, having an

optical fiber to brighten inside the patient's mouth, a slant surface to prevent the

decrease of its suction efficiency and prevent the skin of the mouth from being

sucked into the holes thereof, and a stainless connection tube for economical

sterilization and replacement.

Discussion of Related Art

When a dentist gives a patient a dental treatment such as extracting a

tooth, there is inevitably discharge a lot of blood and saliva through the gums in

the patient's mouth. The blood and saliva standing in the patient's mouth

hinders the dentist in his dental treatment. Therefore, the dentist has to check up

the teeth and gums of the patient. With a suction mirror during a dental

treatment.

With this, however, the dentist cannot hold a suction hose for sucking in and discharging blood, saliva, cleaning water or antiseptic solution standing in

the patients mouth, because he has to hold the suction mirror by one hand and a

dental tool by the other hand. For that reason, at least one practical nurse to

assist the dentist is needed in discharging the blood and saliva in the patient's

mouth with the suction hose.

Therefore, there are caused a lot of problems as follows. If the nurse

does not work hand in hand with the dentist in discharging the blood, saliva,

cleaning water and antiseptic solution standing in the patient's mouth, a

successful treatment for the patient is hard to attain due to undesired blood and

saliva in the patient's mouth and a longer time required for the treatment.

Furthermore, the nurse can make mistakes in assisting the dentist and

spoil the patient's dress with the blood and saliva flowing out of the patient's

mouth, because it is difficult for the nurse to place the suction hose in an

adequate position of the patient's mouth when the dentist looking into the mouth

obstructs the view of the nurse.

In addition to the problems as described above, the space for the dental

treatment in the patient's mouth gets relatively smaller due to the suction mirror,

dental tools and the suction hose introduced in the mouth during the treatment,

which suffers the patient who has to reluctantly open his mouth much wide in

front of the dentist for a long time. FIGS. 8, 9 and 10 illustrate a conventional suction mirror to solve the

above problems. In the suction mirror, as shown in FIG. 8, a disklike stainless

reflecting plate 100 having a polished specular surface 101 is welded to a handle

tube 109. In the rear part of the handle tube 109, a screw tube 110 is provided

to be inserted into a suction hose 200.

Inside the stainless reflecting plate 100, there are provided a hole 102

piercing to the handle tube 109 and an aperture 105 formed rectangularly to the

hole in the center of the hole 102. On both sides of the hole 102, holes 103 and

104 are further formed slantly towards the central aperture 105. The respective

three holes 102, 103 and 104 have apertures rectangularly formed on the fore

parts thereof. ^•

However, the above constructed dental suction mirror involves some

problems in that the sucked materials are caught in the complex structure where

the two bilateral holes 103 and 104 meet at the point of the central aperture 105

formed on the hole 102 piercing to the handle tube 109. Dental calculus, tooth

pieces an plaster fragments (which is used in a dental pretreatment) are hard to

discharge through the handle tube 109 of the conventional suction mirror,

because they are sucked through the three holes 102, 103 and 104 and the four

aperture 105 through 108, and gathered at the edge of the central aperture 105.

Due to the poor suction performance in the prior art, it is required to frequently displace the suction hose 200 form the handle tube 109 so as to open

through the closed holes, which takes too much time.

Moreover, because the holes 102, 103 and 104 are formed rectangularly to

the vertical surface of the stainless reflecting plate 100, the outer edges of them

often get in contact with the skin in the patient's mouth, and thereby resulting

small diameter of the holes lowers the suction efficiency of the suction mirror.

The conventional dental suction mirror whose whole surface is coated

with nickel-chrome is not good for the patient's health. It has no light

equipment for brightening the inside of the patient's mouth, which results in the

difficulty in a precise treatment for the patient.

The suction mirror of the prior art additionally exhibits the disadvantages

in that the handle tube 109 has to inconveniently be taken off from the suction

hose 200 every time for sterilization of it and the suction power is weakened due

to too many holes formed thereon. Moreover, it is required to replace the whole

apparatus when a new suction mirror is to be used.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Reference will now be made in detail to the preferred embodiments of the

present invention, examples of which are illustrated in the accompanying

drawings.

Referring to FIG. 1, in the present invention, holes 14, 15 and 16 piercing

the inside of a stainless reflecting plate 10 make different paths to the stainless

reflecting plate 10 without meeting together at the centering point. Therefore, the

scraps passing through the holes can be successfully discharged through a

stainless connection tube 20 and a handle tube 30 without gathering, which

serves the time required for reluctantly opening through the holes. The area of the holes' outer end portions which contact the skin of a

patient's mouth is small because a slant depression 12 is made in the front side

of the stainless plate 10 and the holes are pierced thereto, which solves the

problem of the prior art that the skin of the mouth is sucked into the holes

during suction.

Additionally, the suction efficiency can be secured because the outer end

portions of the holes are getting apart from the skin inside the patient's mouth

as the diameters of the holes get larger in an oblong form due to the slant

depression 12. Therefore, it is useful for sucking and discharging a long scraps

in the mouth under dental treatment.

The present invention is also effective in maintaining the suction

efficiency to rapidly discharge blood, saliva, cleaning water and antiseptic solution

owing to small number of the holes provided in the suction mirror.

The stainless connection tube 20 is inserted between the stainless

reflecting plate 10 and the handle tube 30. Thus, it is convenient for sterilization

of the stainless reflecting plate 10 and the stainless connection tube 30 by simply

taking the stainless connection tube 20 off from the handling tube 30 after

separating the plastic clip 80. Economically, the handle tube 30 is not needed to

be sterilized.

An optical fiber 50 is inserted into an optical fiber's insertion groove 31 of the handle tube 30 and an optical fiber's end portion 51 is made to be curved

slightly upwards over a polished specular surface 11. Because the plastic clip 80

is inserted into a narrow part 23 of the stainless connection tube 20, the optical

fiber's end portion 51 is curved slightly upwards. Thus, the optical fiber's end

portion 51 under the light emitted by a luminous body brightens the dark inside

of the patient's mouth.

In FIG. 2, the rear part of the optical fiber is desirably affixed to a

suction hose with a plastic ring 90, more preferably, with several plastic rings. If

necessary, it is preferable to use a vinyl tape.

According to the present, it has no harm to a human health because all

components are coated with nickel- chrome and additionally with Si0₂ thereon.

When a new device is to be used, economically we have only to replace the

stainless plate 10 and the stainless connection tube 20. Further, a thin mirror can

be provided on the upper surface of the stainless reflecting plate 10.

It will be apparent to those skilled in the art that various modifications

and variations can be made in the dental suction mirror of the present invention

without departing from the spirit or scope of the invention. Thus, it is intended

that the present invention cover the modifications and variations of this invention

provided they come within the scope of the appended claims and their

equivalents.
