Description

Oral care device and oral care method

The present invention relates to an oral cleaning apparatus for managing an oral cavity, and more particularly, to an oral cleaning apparatus and an oral cleaning method capable of recovering a fluid supplied to the oral cavity without leakage.

Food residues in the teeth or oral cavity may become corrupt as time elapses, causing a mouth odor, or causing various oral diseases such as cavities and gum diseases. To maintain healthy teeth and oral conditions, you should keep your mouth clean, often by brushing and rinsing your mouth with an oral cleanser.

Generally, toothbrushes and floss are used for cleaning teeth. However, it is difficult to completely remove food waste residing between teeth by using a toothbrush and a floss, and excessive use thereof may cause gum or periodontal damage have.

Therefore, in recent years, a variety of oral cleaning apparatuses have been proposed which can wash the mouth by spraying the washing water. A conventional oral cleaning apparatus is an apparatus configured to remove water or a germicidal cleaning liquid at a high pressure to remove foreign substances trapped between the oral cavity and teeth. The apparatus includes a container for containing the cleaning liquid, a spray nozzle, a pump for supplying the cleaning liquid of the container to the spray nozzle As shown in FIG.

However, since the conventional oral cleaning apparatus is configured to spray the cleaning liquid through the spray nozzle, the cleaning liquid splashes to the outside of the oral cavity and can be used only in a limited place such as a bathroom.

Accordingly, as disclosed in Patent Document 1, an apparatus and a method for cleaning an oral cavity, particularly, cleaning an oral cavity, have been developed by supplying a liquid to the mouthpiece structure and discharging the liquid to the mouthpiece structure, thereby suppressing the outflow of the cleaning liquid.

In the case of the device as in Patent Document 1, the mouthpiece takes a double structure and serves as a chamber for dispersing the introduced liquid in order to evenly distribute the liquid to teeth.

However, in the case of such a structure, since the mouthpiece has to have a double structure, it is not only difficult to manufacture but also disadvantageous for liquid control because the liquid is supplied to the teeth after passing through the chamber.

In addition, when the liquid is supplied to the mouthpiece in order to secure a sufficient liquid supply speed, a gap is generated between the mouthpiece and the teeth and the gums due to the liquid being injected into the teeth. In such a case, Liquid may leak between the pieces, which is the same when liquid is sucked from the mouthpiece through the suction pump.

Even if a liquid is partially leaked in the case of a normal user, it is not difficult to discharge the liquid again to the outside of the body. However, in the case of an infant or a patient, the leaked liquid may fall into the throat.

Particularly, in case of unconscious patient, even if some liquid is leaked, it can not be discharged. Therefore, a device for spraying a cleaning liquid can not be used.

In other words, the oral care means of the present invention can be used not only as an advantageous effect on the teeth but also as an apparatus capable of acquiring information as to which advantageous effect should be given by grasping the state of the teeth or oral cavity.

Figures 3 and 4 show perspective views of an embodiment of the management means 100 of the oral care device 1 of Figures 1 and 2 and Figures 5 and 6 and Figures 7 and 8 show cross- Respectively.

3 and 4, the management means 100 includes a fluid inlet 110 through which liquid or air (gas) can flow and a fluid introduced into the fluid inlet 110 through the space 140 A fluid outlet 120 is formed in the fluid outlet 120. The fluid outlet 120 is connected to the outer wall 101 forming the space 140 and the sealing part 130 And a connection part 160 connecting the sealing part 130 and the outer wall part 101. [

The sealing portion 130 on the vertical section may have a constricted shape with a narrow space in comparison with the side end portion of the connection portion or the opening side end portion. For example, it may have a semicircular shape in cross section. Through this, insertion is easy, and a plurality of protrusions 150 can be disposed in the inner space portion.

The connection portion 160 may be made of a material having a thickness or rigidity higher than that of the outer wall 101 or the sealing portion 130 for maintaining the shape and strength of the management means 100. It is also possible to add a frame structure for rigidity to the same material.

The connection portion 160 is formed along the outer surface of the management means 100 except for the rear side of the management means 100 but does not pass through the rear side of the management means 100 and instead, The inner connecting portion and the outer connecting portion are connected to each other. The upper portion and the lower portion of the mandible are different from each other in the rear of the management means 100 so that the connection portion 160 providing the rigidity has no connecting portion disposed behind the management means 100 and only the sealing portion 130 is disposed, It is advantageous.

In general, the management means 100 has a mouthpiece shape, and the outer wall 101 is configured such that one side thereof is opened so that teeth can be inserted. That is, the outer wall 101 has a "C" shape as a whole. A plurality of protrusions 150 are formed on the inner surface of the outer wall 101. The protrusion 150 may be formed of the same material as the outer wall 101, but may be formed of another material.

The outer wall 101 and the protrusion 150 are preferably made of a soluble material and are preferably formed of a soft material such as silicon or silicone rubber so as not to have a sense of resistance to the human body. It is also possible to use.

The sealing portion 130 is connected to the outer wall 101 and the protrusion 150 is not formed so that the sealing portion 130 is formed at the opening side end portion of the outer wall 101 which is an area in contact with the gum or at the distal end portion of the outer wall 101 And may be made of a thinner or thinner material than the outer wall 101. The sealing portion 130 may be formed to have a smooth sealing and an incision for common use in the upper and lower mandibles. The incision may include a small incision line and a posterior incision in the front (lips side) inside and outside (the mouth side) and the back (oral cavity innermost side), and the sealing part 130 may smooth A plurality of cut-out portions may be formed at regular intervals along the circumference of the management means 100. [ The incision part may be formed perpendicularly to the connection part in the direction of the connection part from the free end of the sealing part and may be formed so as to have a larger incision width toward the free end side.

The protrusions 150 are mainly protruded from portions contacting the teeth, and a plurality of protrusions 150 may be uniformly dispersed inside the outer wall 101. As shown in FIG. 4, protrusions 155 may be formed on the protrusions 150. The protrusions 155 may be threaded on the protrusions 150, but protrusions may be formed in other shapes.

The operation of the oral care apparatus 1 of the present invention will be described with reference to Figs. 5 and 6. Fig. The oral care apparatus 1 according to the present invention can prevent the oral cavity of the oral cavity from entering the teeth and the gums in the space 140 of the mouthpiece type management means 100 because the fluid (liquid / gas) is moved only through the suction force of the suction means 15 The suction force is generated in the space portion 140 of the management means 100 so that the air in the space portion 140 moves to the suction means 15 while the rear control portion 90 operates the suction means 15, 130 are brought into close contact with the gums Q and the space 140 is sealed.

The suction force caught in the space portion 140 while the liquid control means 25 is opened causes the liquid in the liquid supply portion 20 to be sucked into the space portion 140 so that the space portion 140 ). &Lt; / RTI > Thereafter, when the liquid control means 25 blocks the inflow of the liquid and the air control means 35 also blocks the inflow of air, the suction means 15 receives negative pressure in the space portion 140, The outer wall 101 is deformed in such a manner that the tooth T is brought into close contact with the tooth T by the pressure difference inside the tooth (refer to FIG. 5 (b) and FIG. 6 (b);

At this time, the protrusion 150 formed on the outer wall 101 moves along the surface of the tooth T, and physically scratches the foreign substances and bacteria attached to the teeth.

When the air control means 35 then opens the external connection passage 30, the pressure of the space portion 140 becomes equal to the external atmospheric pressure, and thereby the external wall (not shown) deformed by the negative pressure in the space portion 140 The protruding portion 150 formed on the outer wall 101 is moved along the surface of the tooth T at this time as well as returning to the original shape (Fig. 5 (a), Fig. 6 So that foreign substances and bacteria attached to the teeth are physically scratched.

If the air control means 35 is repeatedly opened / closed while the suction means 15 is continuously operated, negative pressure is repeatedly formed / released in the space portion 140, (101) is moved. The protrusion 150 formed on the outer wall 101 can be repeatedly moved along the surface of the tooth T so that the surface of the tooth T can be wiped off. Even if the liquid control means 25 and the air control means 35 are intercepted alternately, the outer wall 101 is repeatedly deformed, and the protruding portion 150 can be moved along the surface of the teeth T and wiped.

When there is the additional component supply unit 40 as shown in FIG. 2, the non-water component of the liquid and additional components is supplied to the space unit 140 and then the control of the air control unit 35 described above is performed, The opening / closing of the means 35 is repeated several times, then again supplying liquid or additional components, and again performing the opening / closing of the air control means 35. At the end of the series of processes, water is supplied and aspirated to terminate.

The supply of the liquid and the opening / closing repetition of the air control means 35 perform the same effect as brushing the teeth T, and it is possible to provide an improved effect than simply flowing water.

7 and 8 show a state in which the oral care device of the present invention is installed. As shown in FIGS. 7 and 8, the sealing part 130 is in close contact with the gums Q regardless of the front teeth or the molar teeth, 140 and the protrusion 150 formed on the outer wall 101 scratches the surface of the tooth to provide an improved tooth cleaning.

If necessary, the protrusion 150 can be protruded toward the gum Q. In this case, the protrusion 150 has an effect of irritating the gum.

Fig. 9 shows another embodiment of the management means 100. Fig. 9, the upper outer surface 101a of the outer wall 101 of the management means 100 has the same structure as that of FIG. 7 or 8, but the side outer wall 101b has a bent portion 102 formed like a wrinkle structure do. The bent portion 102 is formed on the side outer wall 101b in this embodiment, but may also be formed on the upper outer surface 101a.

When the bending section 102 is formed on the outer wall 101 as in this embodiment, the outer wall 101 is deformed around the bending section 102 at the time of negative pressure formation, This allows the projection 150 to scrape a specific portion of the tooth T by the deformation of the outer wall 101. [

Considering that the toothless (T) usually lacks brushing, it is self-cleansed by friction between the mucous membrane of the ball and the lips and the area where tooth decay does not occur well, The bending portion 102 is preferably formed so that the outer wall can be deformed about the groove between the tooth and the tooth or the tooth top surface.

Alternatively, a groove having a thickness smaller than that of the other outer wall 101 may be formed instead of the bent portion 102 to induce deformation.

10-12 illustrate other embodiments of the management device 100 of the present invention.

10, the management means 100 is formed in the form of a mouthpiece, and the fluid inlet 110 is disposed at the rear (the innermost side of the mouth) of the mouthpiece-type management means 100, F) flow from the inside of the mouth to the outside (the lip side). At this time, the fluid inlet 110 is disposed on both the rear sides so that it has two inlets, whereas only one of the fluid outlets 120 is disposed. At this time, the inlet and outlet of the fluid may be changed, and the fluid flow may flow from the outside of the mouth to the inside.

Another embodiment is disclosed in Figure 11 wherein the fluid inlet 110 is disposed on one side of the rear of the management means 100 and the fluid outlet 120 is disposed on the other side of the management means 100 rearward. As a result, the fluid flow F passes through the entire tooth region while flowing from the rear side to the rear side from the rear side.

In FIG. 12, the management means 100 'is disposed symmetrically in the up-and-down direction so as to simultaneously manage the upper and lower teeth. At this time, the fluid inlet and the fluid outlet are connected to the side outer wall 101b rather than the upper outer wall 101a of the outer wall 101. [ In the case of this embodiment, since both sides can be managed simultaneously, it is advantageous in terms of management time. In this embodiment, a fluid inlet and an outlet are formed on the molar's posterior (lateral) side surface of the upper and lower teeth, and the upper and lower space portions 140 are opened in the anterior portion. On the other hand, It is also possible to form the inlet and the outlet respectively and to open the upper and lower space portions 140 at the posterior portion.

In FIG. 12, the management means 100 'is formed by joining or attaching the management means 100 as shown in FIG. 11, but it is needless to say that the management means 100' can be integrally manufactured.

13 and 14 show another embodiment of the management device of the present invention.

As mentioned above, not all areas of the tooth are covered with foreign substances, but they are forced to concentrate in specific areas, and the areas where the foreign substances are caught are mainly concave areas or grooves.

13 and 14, the space 140 is formed to correspond to the tooth T, and a contact area in which the outer wall 101 contacts the tooth and the gum, so that the fluid can flow around the region where the foreign matter is caught. (C) and a non-contact area (N) which is convex outwardly from the contact area (C) and through which the liquid passes. Although the protrusion 150 (see FIG. 4) is not formed in the embodiment of FIGS. 13 and 14, the protrusion 150 may be selectively formed only in the non-contact area N. FIG.

The flow rate of the fluid changes depending on the space between the outer wall 101 and the tooth or the gum. If the space between the outer wall 101 and the gum is small, the fluid flow rate decreases. If the space between the outer wall 101 and the tooth or gum is small, Is increased. The faster the fluid flow rate, the greater the debris removal effect.

13 and 14, the non-contact area N through which the liquid passes is formed as a portion frequently adhered to the foreign object, and the portion where the foreign matter does not stick is formed in the outer wall 101 so as to be the contact area C in contact with the teeth or the gums, To provide a structure that limits the area through which the liquid passes and allows it to pass through the required area in a fast flow.

In order to accurately form the contact area C and the non-contact area N in the case of the embodiments of FIGS. 13 and 14, it is necessary to match the mouth structure for each user, so that the management means 100 is preferably manufactured in a customized manner Do.

Fig. 15 shows a flow chart of a method of manufacturing the customized management means in the embodiment of Figs. 13 and 14.

The customized management means includes a duplicate shape preparation step (SlOO) for obtaining the shape of the user's teeth; Attaching a flow path forming member (S110) for attaching the flow path forming member to the replica shape; A flow path forming member curing step (S120) for curing the flow path forming member in the replicated shape to which the flow path forming member is attached; An outer wall forming step (S130) of forming an outer wall by applying a resin material to the replicated shape to which the flow path forming member is attached; An outer wall hardening step (S140) of hardening the resin material adhering to the replica shape; And an outer wall separating step (S130) for separating the formed outer wall. A connection port such as a fluid inlet or a fluid outlet may be formed at the same time as or before the outer wall separating step (S150).

More specifically, the replica shape preparation step (SlOO) is a step of preparing a shape similar to a tooth shape of a user by using a method used in a conventional dentistry. The method of preparing the replicated shape is not particularly limited.

In the step of attaching the flow path forming member (S110), a flow path forming member, which is a light-curing resin in a kneaded state, is attached to the replicated shape prepared at the portion where the foreign matter is easily caught. 16, since the flow path forming member 190 forms the flow path of the management means 100, the flow path forming member 190 is formed over the entire tooth T ', but by self-cleaning action by the oral mucosa or tongue, Except for the parts that do not adhere well. For example, it is formed around the boundary between the gum (Q1) and the tooth (T '), between the tooth and the tooth, or around the tooth top surface groove.

In the flow path forming member curing step (S120), the replica form with the flow path forming member 190 is placed in the light curing unit and light is irradiated to cure the flow path forming member 190. At this time, a port for forming a fluid inlet or a fluid outlet may be attached to the cured flow path forming member, but it is also possible to attach the port after forming the outer wall on the above.

In this embodiment, the flow path forming step is divided into the step of attaching the flow path forming member (S110) and the flow path forming member curing step (S120), but in another embodiment, it is possible to form the flow path from the flow path forming member . For example, it is possible to use a self-polymerizing material without a separate curing step, or it is also possible to form a flow path using a thermoplastic resin and cure.

In the outer wall forming step S130, the silicon material before curing is pressed onto the replicated shape with the flow path forming member 190 attached thereto, and then the outer wall is hardened or pressed with a softened resin material to form an outer wall having a certain thickness. The silicon pressure hardening is performed by pressing a silicon material in a state before curing to a replicated shape with the flow path forming member 190 attached thereto, and then curing the silicon material using a conventional silicon hardening method. The thermoplastic sheet is placed on a resin vacuum molding machine, and then heated to dissolve. Then, a vacuum is applied to adhere the resin material to the replicated shape having the flow path forming member 190 (refer to FIG. 17).

The outer wall hardening step S140 is a step of cooling and hardening the adhered resin material, and it is possible to perform hardening through separate cooling or natural cooling. In this embodiment, the outer wall is divided into an outer wall forming step (S130) and an outer wall hardening step (S140). However, depending on the material used, the outer wall may be formed in a single step without a separate hardening step Of course it is.

The formed outer wall is separated from the replicated shape in the outer wall separation step (S150). A port for the fluid inlet or fluid outlet is formed in the separated outer wall.

15 to 17, the customized management means 100 has a shape corresponding to the user's teeth, provides a fast fluid flow to the part where the foreign object mainly strikes, and the amount of water required for cleaning is small, Do. In particular, in the present invention, it is possible to provide a fast fluid flow without injecting the fluid by the pressurizing means.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
