TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device for oral care, and more particularly, to a hand piece for removing tongue coating used for removing tongue coating and a tip for removing tongue coating attached to the tip thereof.
[0002]
[Prior art]
Oral care is not only to remove bacteria present in teeth and periodontal tissue, but also to perform total care including the tongue, and by doing this, it is possible to maintain and improve oral health. it can. The tongue accounts for about 30% of the entire oral cavity, and removal of tongue coating on the surface of the tongue is very important for oral hygiene. The tongue coating is composed of oral bacteria, saliva components, food residue, exfoliated epithelial cells, and the like, and is a highly viscous deposit. The oral bacteria include various bacteria such as caries or periodontal disease-causing bacteria. In particular, at the base of the tongue at the back of the tongue, the above-mentioned adhering substances are difficult to be removed. The causative bacteria of the periodontitis easily proliferated, and the accumulated deposits were one of the main causes of bad breath.
[0003]
Recently, it has been recognized that the removal of tongue coating is extremely important for oral care, and accordingly, a dedicated device for removing tongue coating has been developed and used at the home care level. As an example of such a dedicated device for removing tongue coating, there is a tongue brush proposed in Patent Document 1. This tongue brush attaches a brush body to the front side of the grip handle, and the user holds the grip handle, rubs the back of the tongue with the brush body, and connects the tongue moss on the back of the tongue to the front side of the grip handle. It is intended to be stored in the formed spoon-shaped cover.

[Problems to be solved by the invention]
The tongue brush as described above has a simple structure, is easily available, and can be easily handled, so that it is suitable for use at a home care level. However, when such a tongue brush is used, it is difficult for the brush body to reach the tongue base at the back of the tongue, and if the brush body is forcibly inserted into the back of the mouth, it may be irritated. In addition, the tongue coating adhering to the deep part of the tongue papillae cannot be removed, and especially in the rear part of the tongue, the flow of saliva is small and dirt easily accumulates on the surface of the tongue. The tongue brush could not sufficiently remove it because it adhered firmly to the surface. Therefore, the amount of tongue coating that can be removed by such a tongue brush is about 20 to 30% of the whole, and it cannot be denied that it is still insufficient from the viewpoint of oral care.
[0006]
Further, since the tongue brush is applied directly to the surface of the tongue, it sometimes stimulates the mucous membrane or damages the mucous membrane. In addition, in the case of a person with dry mouth symptoms (dry mouth), the salivary secretion lowers the self-purifying action of saliva and the inside of the mouth becomes dirty, and the bacteria in the mouth are easily propagated, and the tongue liquor tends to adhere. Increased stickiness makes removal of tongue coating more difficult. As described above, at the home care level, it is difficult for tongue coating to be sufficiently removed, but at the professional level, total oral care including tongue care in addition to tooth and periodontal tissue care is also required. However, despite the fact that it is important for maintaining and improving oral health, there has been no effective tongue coating removal device.
[0007]
The present invention has been made in view of the above circumstances, and is a novel tongue coating removal chip that can perform not only the removal of bacteria present in teeth and periodontal tissue but also total oral care including the tongue. And a handpiece for removing tongue coating using the same.
[0008]
[Means for Solving the Problems]
In order to solve the above problem, a tip for removing tongue coating according to the invention of claim 1 includes a tip base and an action part on the tip side thereof, and is detachably attached to a tip of a handpiece body containing a vibration source. A tongue coating removal chip to be attached, wherein the action portion acts on the tongue surface by vibrating propagated from a vibration source via a tip base, and is provided for tongue coating removal. .
[0009]
The action portion is formed in a ring shape (Claim 2), formed of a brush body (Claim 3), and the brush body is formed of a metal wire in which a large number of hairs are planted in a ring shape. (Claim 4) and the like are adopted. It is desirable that such an action portion is detachably attached to the tip of the chip base (claim 5). As such a detachable attachment mechanism, in addition to the screw-in type, a base portion of the action portion is preferable. However, it is also possible to employ a configuration in which the elastic member is elastically fixed to the tip end of the chip base by the restoring elasticity, and the action portion can be detached from the chip base by a pressing operation against the elasticity (claim 6).
[0010]
As another form of the tip for removing tongue coating, a tip base having an elongated rod shape, the action portion having a small spherical shape and integrally formed at the tip of the tip base is also adopted (claim 7). You.
[0011]
The tip for removing tongue coating is provided with a liquid injection port for communicating with a liquid injection pipe in the main body of the handpiece and ejecting liquid toward an affected portion of the tongue surface when the chip is attached to the main body of the handpiece. It is desirable that they be performed (claim 8). When the operation section is detachable from the chip base as described above, this liquid injection port is provided at the base of the operation section, and the chip base is provided with a liquid injection pipe in the handpiece body. It is desirable to employ a pipe in which a pipe for communicating with the liquid inlet is provided.
[0012]
The handpiece for removing tongue coating according to the tenth aspect of the present invention is a handpiece using the tip for removing tongue coating, and is attached to a handpiece body containing a vibration source and a tip of the handpiece body. The tip for removing tongue coating according to any one of 1 to 9, wherein the vibration from the vibration source is transmitted to the working portion of the chip via the chip base. In addition, in the hand piece main body, a liquid injection conduit communicating with a liquid injection port provided in the tongue coating removal chip is provided (claim 11). A working liquid supply device is connected to the liquid injection pipe, and the liquid is discharged and ejected from the liquid injection port toward the affected portion on the tongue surface. Examples of the working liquid include water, oxidol, sodium bicarbonate solution, physiological saline, low-concentration (0.1% or less) chlorhexidine solution, acrinol solution, low-concentration iodine solution, zinc-containing solution or gel thereof, sodium peroxide , Sodium bicarbonate, and a chemical solution such as a mixed solution containing these as a main component and a bactericide or the like are used.
[0013]
Further, any one of an air type oscillator, an ultrasonic oscillator, a sound wave oscillator, and a motor is adopted as the vibration source. These vibration sources are lightweight, and even if they are built into the handpiece body, the weight of the handpiece itself does not increase, so that even when used for a long time, the operator's fingers can be overwhelmed. Absent.
[0014]
According to the tongue coating removal tip and the tongue coating removal handpiece having such a configuration, the tongue coating removal tip is attached to the tip of the handpiece body, inserted into the oral cavity of the patient, and the action portion is applied to the tongue surface. The switch of the vibration source is turned on. Vibration from the vibration source is propagated to the working part via the tip base, and the vibrating action of this working part causes the tongue coating to float up and be removed from the tongue surface. In particular, since the vibration caused by the vibration source is a continuous mechanical micro-vibration, the vibration action extends to the deep part of the tongue papillae at the back of the tongue, and the tongue coating firmly attached to this part can also be lifted and removed. it can.
[0015]
In addition, in parallel with the above, if water is spouted from the liquid injection port toward the affected part of the tongue surface, the tongue surface is cooled and moistened to relax the tongue and remove tongue coating. It will be easier. When a chemical solution is jetted, the removal of deposits on the tongue surface, bacteria, food debris, and the like is accelerated, and disinfection is performed at the same time. Furthermore, if the operating portion is lightly applied to the tongue surface and the vibration source is turned on in a state where water is contained in the oral cavity of the patient, the vibration is propagated from the operating portion to the water via the tip base, and the vibration action of the water As a result, the tongue coating is liberated and removed from the tongue surface as bubbles. In particular, in the case where water is contained as described above, since the action portion acts indirectly on the tongue surface and the water exhibits a lubricating effect, irritation to the tongue surface is reduced and the mucous membrane is not damaged.
[0016]
When a brush body is used as the action part, the action is applied to the deep part of the tongue papillae by the brushing action by vibration, and the tongue sticking to this part is suitably removed. As the brush body, an inter-tooth brush-shaped brush body in which a bristle body is implanted in the thrust direction at the base of the action portion or a bristle body in the radial direction is implanted in a metal wire in a straight line, A ring-shaped member obtained by implanting a hair is used. In particular, in the case of this ring-shaped product, vibrations are concentrated and amplified at the center of the ring, and when a liquid is added thereto, tongue coating is bubbled at the center and released from the tongue surface . Since the brush body is worn by use, it is economical if the brush body is used as a consumable and is detachably attached to the tip of the chip base.
[0017]
In addition, when using a tip in which a small spherical portion is integrally formed as a working portion at the tip of an elongated rod-shaped tip base, the acting portion has a small spherical shape, so that a soft feeling is given to the patient without damaging the tongue papillae. Even if it is inserted into the back of the tongue or the lower root, there is little irritation, and the patient does not get tired. In addition, since the tip base is in the shape of an elongated rod, it can be appropriately formed so as to conform to the shape of the surface of the tongue. The convenience of handling is improved by bending the shape to a shape that can function.
[0018]
The tongue coating removal handpiece can also be used as a dental scaler by replacing the tongue coating removal tip with a scaler tip. When used as a scaler, it is necessary to increase the vibration power as compared with the removal of tongue coating, so it is desirable to provide a power adjusting means to the vibration source. In this way, if the dental scaler can also be used, the dentist can provide total oral care including tartar removal, tooth surface cleaning, and tongue coating removal in a short time and efficiently without increasing the number of facilities to the left. Can be performed.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described. 1 is a partially cutaway exploded view of an embodiment of the tongue coating removal handpiece of the present invention, FIG. 2A is an enlarged view of a part X in FIG. 1, and FIG. 2B is an AA in FIG. FIG. Reference numeral 1 denotes a handpiece main body including a grip portion to be gripped by an operator. The handpiece main body 1 has a built-in vibration source 10 using air, ultrasonic waves, magnetostriction, or electrostriction as a power medium. At the base end of the handpiece body 1, a pipe or an electric wire for supplying air to the vibration source 10, and a liquid injection pipe communicating with a liquid injection pipe in the handpiece main body 1 described below (both of them). (Not shown) are connected and connected to a flexible hose 11.
[0020]
A tip 2 for removing tongue coating is attached to the tip of the handpiece body 1. The tip 2 for removing tongue coating comprises an elongated rod-shaped tip base 3 and an action portion 4 on the tip side thereof. The chip base 3 is made of metal or resin, and includes a male screw part 31 on the base side, an elongated body part 32, and a fixing part 33 on the tip side thereof. It is screwed and fixed to the tip. In normal use, the tip base 3 is not frequently replaced according to the contents of the treatment, unlike the action part 4. However, it is necessary to clean the tip base 3 itself, to replace the tip base 3 due to damage, or to perform other maintenance. In some cases, the male screw portion 31 can be separated from the handpiece body 1 by loosening the male screw portion 31. The total length of the tip base 3 is determined so that the action portion 4 reaches the back of the tongue, and the elongated body portion 32 is appropriately bent so as to be parallel to the tongue surface and to remove tongue coating. In some cases.
[0021]
The fixing part 33 is a part for detachably attaching the operation part 4. The action portion 4 is formed by bending a base portion 40 screwed into the fixing portion 33 with a male screw portion 40a and a metal wire 41b having a hair body 41a planted in a ring shape, and is caulked and fixed to the base portion 40. Brush body 41. The base 40 is formed with a liquid inlet 42 for ejecting liquid to the affected part, and the liquid inlet 42 is formed through a pipe 34 provided in the chip base 3 along the longitudinal direction thereof. It communicates with a liquid injection pipe line 12 provided in the piece body 1.
[0022]
FIG. 3 is a diagram illustrating a usage state using the tongue coating removal handpiece of the embodiment, and FIG. 4 is a diagram schematically illustrating a tongue papilla at the back of the tongue. The tip base 3 is formed in an elongated rod shape, and is bent into a shape in which the action portion 4 easily contacts the tongue surface T as shown in the figure. As shown in FIG. 1, when the vibration source 10 is turned on with the tongue debris removal chip 2 screwed to the handpiece body 1, the vibration generated by the vibration source 10 passes through the chip base 3. Propagated to the action section 4. In this way, if the brush body 41 as the action portion 4 is applied to the tongue surface T, the tongue coating on the tongue surface T is removed by the contact of the brush body 41 and the vibration action.
[0023]
At this time, if water or a chemical solution is sprayed from the liquid inlet 42 toward the affected portion of the tongue surface T, the cleaning action of these liquids and the vibration action of the brush body 41 are combined, so that the tongue surface T Tongue sticking to the surface is more easily released. In particular, since the brush body 41 is formed in a ring shape, the vibration is concentrated and amplified at the center thereof, and due to the concentration of the vibration, the vibration adheres to the deep part (bottom part) T2 of the tongue nipple T1 shown in FIG. The tongue liquor that floats also floats up, and is preferably removed by washing.
[0024]
Further, in a state where water is contained in the oral cavity of the patient, the brush body 41 is lightly applied to the tongue surface T so as to be immersed in the water, and the brush body 41 is vibrated as described above. The vibration propagates to the water, and the tongue liquor is released from the tongue surface T due to the vibration action of the water, so that the tongue surface easily floats. In such a usage mode, since the brush body 41 only lightly touches the tongue surface T and has a lubricating effect of water, the stimulation to the tongue surface T is small, and there is no fear of damaging the tongue surface T.
[0025]
As shown in FIG. 4, the tongue surface T at the back of the tongue is composed of a large number of mushroom-like or thread-like tongue papillae T1. Saliva may not easily flow around the back of the tongue, and food debris and the like may accumulate in the deep portion T2 between the tongue papillae T1 and tend to adhere firmly, and this becomes tongue coating. The width dimension W of the tongue papilla T1 is 0.9 to 1.0 mm, and the height H is about 0.6 to 0.8 mm for the mushroom papilla and about 2 mm for the thread papilla. The amplitude of the action portion 4 suitable for removing tongue coating adhering to the deep portion T2 is 50 to 400 μm, the material of the brush body 41 is nylon or the like, the hair length of the hair body 41a is 1.5 to 3.5 mm, and the thickness is Is 50 to 100 μm and the flocking density is 1 to 5 fibers / mm ² It has been experimentally confirmed that the ring diameter of the wire 41b is preferably 7 to 12 mm. When an ultrasonic oscillator is used as the vibration source 10, the power level is lowered, and when an air oscillator is used, the air pressure is 3.0 to 3.8 kg / cm. ² It was experimentally confirmed that the frequency was preferably 4 to 7 kHz.
[0026]
As the pneumatic oscillator, for example, those disclosed in Japanese Patent Publication No. 60-1017 and Japanese Patent Application Laid-Open No. 56-83341 can be used. When an ultrasonic oscillator is used, a magnetostrictive element, an electrostrictive element, a well-known Langevin type vibrator, a ceramic vibrator, a piezoelectric vibrator, or the like can be used. In addition, a vibrator disclosed in Japanese Patent Application Laid-Open No. 2002-176758, a vibrator that converts the rotation of a well-known motor into reciprocating vibration, or the like can be used.
[0027]
The bristle body 41a of the brush body 41 may be worn due to long-term use. In such a case, the male screw portion 40a can be loosened and replaced with a new one. Further, a suitable chip is selected from various types of chips described later according to the state of the affected part, and is used by being attached to the tip of the chip base 3. Therefore, it is economical because only the action part 4 can be replaced as a consumable, and it is possible to carry out an appropriate tongue coating removal treatment according to the state of the affected part. Since the tip base 3 is also detachable from the handpiece body 1, it is extremely convenient for sterilization, disinfection and cleaning. A dedicated wrench-like tool (not shown) prepared separately is used for attaching and detaching the tip and the tip base.
[0028]
FIG. 5 shows a tip 2 for removing tongue coating according to another embodiment. The tip 2 for removing tongue coating comprises an elongated rod-shaped tip base 3 made of metal and a small spherical action part 4 integrally formed at the tip thereof. The tip base 3 is detachably attached to the tip of the handpiece main body 1 with a male screw portion 31 at the base, similarly to the first embodiment. The body 32 of the chip base 3 is bent and formed into an appropriate shape. In the illustrated example, it is shown that the portion is further bent to the back side of the paper at the Y portion. With such a shape, the action portion 4 can be brought into contact with the surface of the tongue so as to smoothly slide along the shape of the tongue side, the back of the tongue, and the shape of the base of the tongue.
[0029]
A pipe 34 is provided at the base of the chip base 3, and a liquid inlet 35 communicating with the pipe 34 is opened at the base so as to face the working section 4. The pipe 34 communicates with a liquid injection pipe (not shown) provided in the handpiece body 1 in the same manner as described above. The tip 2 for removing tongue coating having such a configuration is attached to the tip of the handpiece main body 1 and inserted into the oral cavity, and the vibration source is turned on to be used for removing tongue coating. The action part 4 is slid on the surface of the tongue with a slight vibration. At this time, water or a chemical is injected from the liquid inlet 35 toward the affected part.
[0030]
In the tongue coating removal operation as described above, the action portion 4 is brought into sliding contact with the tongue surface of the tongue side, the back of the tongue or the tongue base with vibration. At this time, water or a chemical is injected from the liquid inlet 35 toward the affected part. Then, the tongue coating is released from the tongue surface and removed by the vibration / sliding action of the action section 4 and the ejection of the liquid. Since the action part 4 is small spherical and is operated to slide smoothly on the tongue surface, it does not damage the tongue papillae on the surface of the tongue, and there is little irritation even when it is inserted into the back of the oral cavity, so that the patient can be exhausted. Nor. It is preferable that the diameter of the small spherical action portion 4 is 1.2 to 2.0 mm, and such a size allows the action portion 4 to be slightly fitted between the tongue papillae T1 shown in FIG. As a result, the vibration also propagates to the deep part T2, and the floating and release of the tongue coating adhering to this part are promoted.
[0031]
FIG. 6 shows another embodiment of the tip for removing tongue coating, and FIGS. 6 (a) and 6 (b) show a modification in which the action section 4 is a brush body. In the example of FIG. 6A, hairs 41a are radially implanted in a straight metal wire 41b, and the hairs 41a are cut into a conical shape. In the example of FIG. 6B, the hairs 41a are implanted directly in the thrust direction on the base 40. These have a shape similar to an interdental brush and are used for relatively mild removal of tongue coating, and are gentle on the tongue surface and cause little discomfort to the patient. In addition, it can be used as an interdental brush, and tongue debris removal and interdental cleaning can be performed in parallel, which is effective in performing total oral care. Other configurations are the same as those of the first embodiment, and thus the same reference numerals are given to the common parts, and the description thereof will be omitted.
[0032]
The tip 2 for removing tongue coating shown in FIG. 7A has an action section 4 in a ring shape, and the ring action section 4 and the tip base 3 are integrally formed. FIG. 7B is a view taken along the line BB of FIG. 7A, and FIG. 7C shows a modified example thereof. In this example, since the action section 4 is not worn like a brush body, it is not necessary to be left detachable with respect to the chip base 3 as far as the left. When the action portion 4 is ring-shaped, the vibration from the vibration source is concentrated and amplified at the center thereof as in the first embodiment, thereby improving the tongue coating removal effect and contacting the tongue surface. The area is large and the removal procedure is performed efficiently. In the example of FIG. 7 (c), the action portion 4 is curved so as to follow the concave shape of the tongue surface, and the tongue coating removal performance is further improved. Since other configurations are the same as those described above, the same reference numerals are given to the common portions, and the description thereof is omitted here.
[0033]
FIGS. 8A, 8B, and 8C are modifications of the example of FIG. 7, in which the ring-shaped acting portion 4 is formed in an open ring shape. When the ring is opened in this manner, a characteristic occurs in which the amplitude is small at the base of the ring and the amplitude increases toward the tip. Therefore, when the action portion 4 is operated along the surface of the tongue, a removal effect corresponding to various tongue coatings adhered to the surface of the tongue is exerted by its vibration characteristics. The difference between (a), (b) and (c) is a difference in shape, and various shapes such as an annular shape, a horizontal or vertical ellipse or an oval, and an oval shape can be adopted. Since other configurations are the same as those described above, the same reference numerals are given to the common portions, and the description thereof is omitted here.
[0034]
FIGS. 9A and 9B show a modified example of how to attach a chip, and FIGS. 10A and 10B are enlarged longitudinal sectional views of the main part. A tip base 3 is detachably attached to the tip of the handpiece body 1 with a male screw portion 31 at the base thereof, and a fixing portion 5 is provided at the tip of the tip base 3. An operator accommodating hole 50 is dug from the distal end side of the fixing portion 5, and an operator 51 and a compression spring 52 for urging the operator 51 toward the distal end side of the fixing portion 5 are provided in the accommodating hole 50. Is housed. 53 is a cap for preventing the actuator 51 from jumping out, and is screwed and fixed to the fixing portion 5. In the screw-fixed state of the cap 53, the pressing operation portion 51a of the actuator 51 protrudes from the opening thereof, and the pressing operation portion 51a is pressed against the elasticity of the compression spring 52 to operate. The child 51 can reciprocate left and right in the accommodation hole 50.
[0035]
The actuator 51 has a long hole 51b penetrating vertically and having a long diameter along the biasing direction of the compression spring 52. On the other hand, the fixing portion 5 is formed with a holding hole 50a which is orthogonal to the accommodation hole 50 and communicates with the long hole 51b.
[0036]
When attaching the tip 2 for removing tongue coating to the fixing portion 5, first, the pressing operation portion 51 a is manually pressed in against the elasticity of the compression spring 52, and the base 40 of the action portion 4 is connected to the holding hole 50 a and the length. Insert into the hole 51b. Next, when the pressing of the pressing operation section 51 a is released, the actuator 51 is pushed back to the tip side of the chip base 2 by the restoring elasticity of the compression spring 52. At this time, the base 40 of the working portion 4 is elastically and securely fixed by the inner wall of the elongated hole 51b and the inner wall of the holding hole 50a accompanied by the biasing elastic force of the compression spring 52.
[0037]
When removing the action section 4, if the pressing operation section 51 is pushed again, the above-mentioned biasing elasticity of the action section 4 with respect to the base 40 is released, so that the action section 4 can be taken out. As described above, in this embodiment, the one-touch operation of the pressing operation unit 51 allows the attachment / detachment of the action unit 4, thereby eliminating the need for a dedicated tool and simplifying the operation. The exchange of the various action parts 4 according to the state of the part can be performed flexibly and efficiently.
[0038]
As shown in FIGS. 10 (a) and 10 (b), small-diameter recesses 40a and 40b are formed in the base portion 40 of the action portion 4, while protrusions which fit into the small-diameter recesses 40a and 40b are formed on the inner wall of the long hole 51b. Parts 51c and 51d are formed. In a state in which the action portion 4 is attached and fixed, the action portion 4 is prevented from coming off by mutual fitting of the small-diameter concave portions 40a, 40b and the protrusions 51c, 51d. Other configurations are the same as those of the above-described embodiment. Therefore, the same reference numerals are given to common portions, and description thereof will be omitted.
[0039]
FIG. 11 shows a modification of the method of attaching and detaching the operation section 4 by the one-touch operation shown in FIGS. 9 and 10, such that the operation section 4 is detachably attached to the tip of the chip base 3 in a straight line. It was done. Accordingly, since the internal structure is the same except that the direction of the fixing portion 5 is different from that shown in FIGS. 7 and 8 by 90 °, detailed description thereof is omitted.
[0040]
In the above description, the handpiece is mainly used for removing tongue coating at a professional level. However, the handpiece of the present invention can be commercialized for home care. In the above embodiments, all the devices provided with a liquid injection mechanism have been illustrated. However, when a handpiece or the like dedicated to liquid injection is used together, the liquid injection mechanism can be omitted. Furthermore, if the tip for removing tongue coating of the present invention can be attached to an existing electric toothbrush, total oral care such as cleaning of teeth and removal of tongue coating at home can be easily and conveniently performed.
[0041]
【The invention's effect】
According to the tongue coating removal chip of the present invention and the tongue coating removal handpiece using the same, the vibration from the vibration source is propagated to the action section via the chip base, and the action section vibrates to cause the tongue coating to float. Is released and removed from the tongue surface. In particular, since the vibration caused by the vibration source is a continuous mechanical microtremor, the vibration action extends to the deep part of the tongue papillae behind the tongue, and also lifts and removes tongue moss firmly attached to this part Can be. Further, since the tongue coating removal tip is detachable from the handpiece body, it can be selectively used as appropriate according to the symptoms (claims 1 and 10). In the case of having a liquid injection function, water or a chemical solution is sprayed onto the affected part in parallel with the vibration, so that the action of releasing the tongue coating from the tongue surface is promoted, and the removal is more reliably performed. 8, 11).
[0042]
When the brush body is used as the action part, the vibration is propagated also to the tip of the hair constituting the brush body, whereby the tongue coating adhering to the deep part of the tongue nipple can be released and removed. 3, 4). In the case of the ring-shaped acting portion, the tongue coating is suitable for removing a wide range of tongue coating, and the liberation of the tongue coating is promoted by the action of concentrating and amplifying the vibration at the center (claims 2 and 4). If the tip for removing tongue coating is composed of an elongated rod-shaped tip base and the action part on the small ball at the tip, even if it is inserted deep into the oral cavity, there is little irritation to the tongue surface, and the patient does not get rid of It can be applied smoothly to a wide range from the tongue side to the back of the tongue (claim 7).
[0043]
If the operating portion is detachably attached to the tip of the tip base, the economical burden can be reduced when the operating portion is a consumable such as a brush body. In addition, if a one-touch mechanism by finger operation is adopted as the attachment / detachment mechanism, a dedicated tool is not required, and the tongue coating removal treatment is efficiently performed (claim 6).
[0044]
If any of an air-type oscillator, an ultrasonic oscillator, an acoustic wave oscillator, and a motor is used as the vibration source, the handpiece itself does not become heavy and the burden on the user can be reduced (claim 12). Further, if the tip for removing tongue coating of the hand piece for removing tongue coating of the present invention is used by replacing it with a dental scaler tip, it can also be used as a dental scaler. It is extremely effective in performing total oral care such as removal (claim 13).
