3 is a disassembled perspective view illustrating the configuration of the dental mouthpiece 100. Fig. 4 is an exploded perspective view of the dental mouthpiece 100 according to the present invention. FIG. 2 is a cross-sectional view showing a state in which the light emitting diode is coupled to the light emitting diode.

As shown in FIG. 4, the mouthpiece 100 of the present invention is used in combination with the adapter a of the measuring device A. FIG. At this time, the measuring device (A) may be a smoking meter for smoking measurement, or a spirometer for measuring the volume of the spirometer.

The dental mouthpiece 100 of the present invention is provided with a filter 120 capable of filtering out foreign matter (C) such as virus. The foreign matter C is blocked by the filter 120 and only the exhalation unit B is inside the measuring unit A even if the foreign matter C flows together with the exhalation unit B supplied from the mouth of the examinee into the mouthpiece 100 Lt; / RTI >

Thus, it is possible to solve the problem that the foreign matter (C) flows into the measuring instrument (A) and causes secondary infection to other examinees.

The mouthpiece body 110 supplies the inside of the measuring device A to the breathing apparatus B flowing from the mouth of the examinee. The mouthpiece body 110 is formed in the form of a hollow tube having both ends opened. An insertion hole 113 is formed at one end of the mouthpiece body 110 and connected to the adapter a of the measuring instrument A. The other end is connected to the mouth of the examinee and inserted into the inlet hole 111, .

The diameter of the mouthpiece body 110 is formed such that the examinee can easily hold the mouthpiece. Since the mouthpiece body 110 is used only once, the mouthpiece body 110 is formed of a cheap material.

In the preferred embodiment of the present invention, the mouthpiece body 110 is formed in the shape of a cylindrical hollow tube, but this is merely an example, and may have various sectional shapes and lengths.

On the other hand, on the side of the coupling hole 113 of the mouthpiece body 110, a filter supporting jaw 115 is provided so as to project radially inward. The filter support jaw 115 is formed to extend in the circumferential direction and toward the center of the certain area to prevent the filter 120 received therein from being separated from the outside.

The filter 120 can be held in contact with the filter support jaw 115 to maintain a stable position within the mouthpiece body 110 as shown in FIG.

It is preferable that the extension length of the filter support jaw 115 is formed to a minimum area that can sufficiently support the filter 120 in a range that does not affect the influx of the exhalation machine B. [

The filter 120 is accommodated in the mouthpiece body 110 to block the foreign body C moving along the mouthpiece body 110. The foreign substance (C) includes bacteria or viruses, and includes saliva or saliva contained in the patient's exhalation.

 The filter 120 is formed of a non-woven material of an environmentally friendly material. The filter 120 is formed in a disc shape having an outer diameter corresponding to the inner diameter of the mouthpiece body 110.

 As an example of the filter 120, when a PP material manufactured by a needle punching method with a thickness of 2.5 mm and a weight of 165 g is used, it was tested that it can block 99.90% of bacteria and 99.90% of viruses on the basis of Nelson.

On the other hand, a fitting protrusion 121 protruding downward is provided on the outer circumferential lower portion of the filter 120 as shown in FIG. The fitting protrusion 121 is fitted into the filter fitting groove 131 of the filter fixing member 130 so that the filter 120 and the filter fixing member 130 are coupled to each other.

As shown in the figure, the shape of the fitting protrusions 121 may be variously formed in such a manner that the male and female protrusions are physically inserted and fixed in place, in addition to the shape of the protrusions formed on the outer periphery.

The filter fixing member 130 is supported on the mouthpiece body 110 such that the filter 120 is fixed in position within the mouthpiece body 110. The filter fixing member 130 is formed of an elastic material having an outer diameter larger than the inner diameter of the mouthpiece body 110. For example, the filter fixing member 130 may be formed of sponge, silicon, or the like.

The filter fixing member 130 having a larger diameter than the mouthpiece body 110 is inserted into the mouthpiece body 110 in a state of being elastically compressed by the pressure of the operator. And is inserted into the mouthpiece body 110 and expanded into an initial state while being inserted into the mouthpiece body 110 and fixed in position.

A filter coupling groove 131 into which the fitting protrusion 121 is inserted is formed in the outer periphery of the coupling surface to which the filter fixing member 130 and the filter 120 are coupled. In this state, the filter fixing member 130 is resiliently compressed and inserted into the mouthpiece body 110. In this state, the filter fixing member 130 and the filter 120 are fixed to each other, .

The operator moves the filter fixing member 130 to the coupling hole 113 of the mouthpiece body 110 by using a long rod or the like. The filter 120 hits the filter support jaw 115 of the mouthpiece body 110 and is fixed in position within the mouthpiece body 110 as further movement is inhibited.

The use of the filter fixing member 130 is for fixing the filter 120 inside the mouthpiece body 110 without using an adhesive harmful to the human body. The concave and convex shapes of the fitting protrusion 121 and the filter coupling groove 131 are used for coupling the filter 120 and the filter fixing member 130 without using an adhesive for the same reason.

As a result, it is possible to block the foreign matter C and at the same time eliminate the use of elements harmful to the human body.

The use process of the dental mouthpiece 100 according to the present invention having such a configuration will be described with reference to Figs. 2 to 4. Fig.

The operator inserts the filter 120 and the filter fixing member 130 into and from each other as shown in Fig. Then, the filter fixing member 130 to which the filter 120 is coupled is inserted into the mouthpiece body 110. The filter fixing member 130 is pressed toward the coupling hole 113 of the mouthpiece body 110 by using a long rod or the like.

When the filter 120 touches the filter support jaw 115 and is no longer moved, the pressure is stopped.

The mouthpiece 100 to which the filter 120 is coupled is coupled to the adapter a of the measuring device A as shown in Fig. Then, the measuring instrument A is operated, and the subject inserting the mouthpiece 111 of the dental mouthpiece 100 into his / her mouth and blowing the breathing mouth B is blown.

As shown in FIG. 4, when the exhalation machine B is introduced into the mouthpiece body 110, foreign substances such as saliva, viruses and the like are introduced together. When the exhalation machine B and the foreign matter C move and reach the filter 120, the exhalation machine B passes and the foreign substance C is blocked.

As a result, only the exhalation unit B can be introduced into the measuring instrument A, and secondary infection through the measuring instrument A can be prevented.

As described above, the dental mouthpiece according to the present invention can block a foreign object introduced together with the exhalation unit by receiving the filter therein. As a result, it is possible to prevent foreign matter from flowing into the measuring instrument coupled with the mouthpiece, thereby preventing secondary infection by foreign matter.

Further, since the foreign matter does not flow into the measuring instrument, it is possible to prevent the life of the measuring instrument from shortening or malfunctioning due to foreign matter.

In addition, the mouthpiece for use in the present invention is advantageous in that it is harmless to the human body because the filter is housed in the mouthpiece body by the filter support member without using an adhesive.

Further, since the filter is fixed to the inside of the mouthpiece body made of paper without using the adhesive by the filter fixing member of the sponge material, the whole structure is simple and the manufacturing cost can be made low.

In the meantime, the dental mouthpiece body 110 may be formed with an antifouling coating layer coated with a composition for preventing contaminants so as to effectively prevent and remove the contaminants.

The anti-contamination coating composition contains alkanolamide and amphopropionate in a molar ratio of 1: 0.01 to 1: 2, and the total content of alkanolamide and amphopropionate is 1 to 10 Weight%.

The molar ratio of alkanolamide and amphopropionate is preferably in the range of 1: 0.01 to 1: 2. When the molar ratio is out of the range, the coating property of the base material is lowered or the moisture adsorption on the surface is increased, There is a problem to be removed.

The alkanolamide and amphopropionate are preferably used in an amount of 1 to 10% by weight in the aqueous solution of the total composition. When the amount is less than 1% by weight, the applicability of the base material is deteriorated. When the amount is more than 10% by weight, So that crystal precipitation is likely to occur.

On the other hand, as a method of applying the present anti-fouling coating composition onto a substrate, it is preferable to coat it by a spray method. The thickness of the final coated film on the substrate is preferably 500 to 2000 angstroms, more preferably 1000 to 2000 angstroms. When the thickness of the coating film is less than 500 ANGSTROM, there is a problem that it deteriorates in the case of a high-temperature heat treatment. When the thickness is more than 2000 ANGSTROM, crystallization of a coated surface tends to occur.

The anti-contamination coating composition may be prepared by adding 0.1 mol of alkanolamide and 0.05 mol of amphopropionate to 1000 mL of distilled water, followed by stirring.

In addition, the filter 120 may be coated with a perfume material having a function of treating respiratory diseases or the like, thereby exhibiting an effect on the user's fatigue recovery and health promotion.

The functional oil may be mixed with 95 to 97% by weight of a perfume, 3 to 5% by weight of a functional oil, 50% by weight of a functional oil, 50% by weight of a tangerine oil, And 50% by weight of palmitoleic acid oil.

Here, the functional oil is preferably mixed with 3 to 5% by weight based on the perfume. If the mixing ratio of the functional oil is less than 3% by weight, the effect is insignificant. If the mixing ratio of the functional oil exceeds 3 to 5% by weight, the function is not greatly improved, but the manufacturing cost is greatly increased.

Tangerine oil in functional oil is citronellol, linalool, cital, etc. It has good effect on relieving stress by preserving, shaking and sedating.

 Palmitoleic acid oil is antioxidant, good for dry or aged skin, and has excellent effects on cell regeneration, sterilization, skin inflammation treatment.

As the functional oil is coated on the filter 120, it contributes to restoration of the user's fatigue and health improvement.

The filter fixing member 130 may be made of a rubber material. The ratio of the raw material content of the filter fixing member 130 to the rubber fixing material 130 may be 60% by weight of rubber, 33 to 36% by weight of carbon black, 2 to 5% , And 1 to 3% by weight of sulfur as a promoter.

When the content is less than 33% by weight, the elasticity and abrasion resistance are reduced. When the content is more than 36% by weight, the rubber content of the main component is relatively small and the elasticity may be lowered. , And 33 to 36% by weight.

The antioxidant is selected from 3C (N-PHENYL-N'-ISOPROPYL-P-PHENYLENEDIAMINE) or RD (POLYMERIZED 2,2,4-TRIMETHYL-1,2-DIHYDROQUINOLINE) If the content is less than 5% by weight, the content of the rubber as a main component may be relatively small and the elasticity may be lowered. Further, since the cost of the antioxidant is high, To 5% by weight is appropriate.

Sulfur, which is an accelerator, is mixed in an amount of 1 to 3% by weight. When less than 1% by weight, the effect of vulcanization is insignificant in the heating process during molding, so 1% by weight or more is added. If the content is more than 3% by weight, the content of the rubber as the main component may be relatively small and the elasticity may be lowered. Therefore, 1 to 3% by weight is appropriate.

Accordingly, since the elasticity, toughness and rigidity of the filter fixing member 130 are increased, the durability of the filter fixing member 130 is improved and the lifetime of the filter fixing member 130 is increased.

The embodiments of the mouthpiece for an arm according to the present invention described above are merely illustrative and those skilled in the art will appreciate that various modifications and equivalent embodiments can be made without departing from the scope of the present invention. You will know. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments.
