Description Soft interdental cleaning device Technical field

Plaque adhering to the tooth surface and periodontal tissue becomes a breeding ground for bacteria that cause tooth decay and alveolar pyorrhea, and is a major cause of tooth loss. The present invention relates to an oral cleaning tool which is particularly suitable for controlling plaque in an interdental region causing periodontal disease. Technology background

In general, the two major diseases of tooth loss are caries and periodontal disease.Especially, in cases of periodontal disease and gingival regression, plaque control of the interdental region by a common tooth brush is common. There are limitations, and oral cleaning aids such as interdental brushes are widely used. A typical cleaning aid interdental brush is a metal twisted wire concentrically wrapped with a nipple brush, but if the tip hits the gingiva when the interdental part is inserted, it often damages the gingiva. However, if the metal at the tip of the tooth hits the teeth, it will cause discomfort, and the repeated use of the metal twisting wire will cause a high risk of breakage during cleaning due to metal fatigue.Therefore, there are a number of problems to establish in daily oral care. there were. Furthermore, if a pre-curve is applied to the cleaning brush to match the insertion direction, the metal wire itself has no shape restoring property, and there is a danger that unpolished portions will be generated at the root indentation and the like. As mentioned above, the usefulness of interdental plaque control is high. However, when inserting an interdental cleaning device into the interdrum space for cleaning the interdental region using an oral cleaning aid, pain and discomfort can be caused at the same time without damaging the gingiva at the tip of the cleaning portion. It can be easily inserted without causing any inconvenience, and it can be easily inserted into the interdental area where the insertion direction is restricted, such as a maze with a complex root shape, without any resistance. Another object of the present invention is to provide an interdental cleaning aid that is comfortable and less likely to be damaged during the cleaning operation. Disclosure of the invention

The present invention has been made to achieve the above-mentioned object, and a first invention is to provide a cross-sectional shape of a shaft portion of an interdental brush with a tapered shape, a reverse tapered shape, or providing a detail and a thick portion. In this way, any part can be made into a shape with higher stress deformation due to the use of a resin that has both the appropriate elasticity, shape resilience, and flexibility, and any part that exhibits elasticity by being partially baked or annealed. By using a metal that has been adjusted to a certain level, the sliding motion, the rotational motion, or the sliding motion, such as that of Japanese Patent Application No. 2000-38080, Japanese Patent Application No. 2001-1702. This is an interdental brush that is connected to the movement shaft of an electric interdental cleaning device that generates a rotating slide motion or a manual interdental cleaning device and cleans the tooth surface, gingiva and sulcus of the interdental area.

With the interdental brush having such a shaft, the insertion direction of the oral cavity of the manual interdental cleaning device or the electric interdental cleaning device with the tongue or lips is anatomically restricted, and the axial direction of the interdental cleaning unit When it is difficult to match the tongue-like penetration direction of the interdental space between the hourglass and the gingival side of the gingival side or the gingival side of the gingival side (palate side),頰 If pressed lightly in the tongue direction, the shaft of resin or metal, which has both appropriate elasticity and shape resilience, will be deformed at the tip with appropriate elasticity to serve as a guide. By doing so, insertion becomes possible easily,

In addition, after insertion into the interdental area, the interdental cleaning section slides and rotates. Or, by rotating and sliding, the shaft can be adapted to the complex anatomical shape of the interdrum space by simply inserting into the interdental space, such as a maze with a complex root shape. By deforming, the surface of the cleaning part is pressed against the tooth surface, gingiva and gingival sulcus of the interdental part without excess and deficiency, and fine irregularities on the surface remove plaque in the same part and clean it, and improve shape resilience and toughness Poor materials of the interdental cleaning part and the shaft part can prevent the deformation and fracture.

The second invention is a highly compressible natural cylindrical or polygonal pillar having a smooth rounded tip so as to enclose the tip of the shaft of the crown cleaning device according to the first invention. An interdental brush in which a sponge (special continuous porous body) made of fibrous material, synthetic fiber, nonwoven fabric made of the above-mentioned fiber, natural rubber, synthetic rubber, or synthetic resin is adhered or welded is disclosed in Japanese Patent Application No. 2000-200 3 8 0 6 8 6, Patent application 2 0 0 1-2 3 0 2 0 7 This is an interdental cleaning device equipped with an interdental cleaning sponge connected to the holding portion of the interdental cleaning device This sponge is made of elastic, highly compressible natural fiber, natural rubber, synthetic rubber, or synthetic resin. (Continuous porous body) By simply inserting the sponge into the sponge, the various shapes of the sponge surface are brought into contact with the tooth surface, gingiva and gingival sulcus, and fine irregularities on the surface of the sponge (continuous porous body) made of natural fiber, natural rubber, synthetic rubber, or synthetic resin. This enables the same part to be cleaned.

In addition, the shaft tip is covered with a sponge (continuous porous body) made of elastic, highly compressible natural fiber, natural rubber, synthetic rubber, or synthetic resin. To prevent marginal papillary gingiva injuries, and, even when the insertion direction of the shaft into the interdrum space is restricted tongue, along with the shaft, which has appropriate elasticity, shape resilience, and flexibility The intentionally designed more elastic (deformable) part of the interdental cleaning part has moderate elasticity. It can be easily inserted into the interdental cleaning part because it is deformed, and the interdental cleaning part is highly compressible by simply inserting it into the interdental part such as a maze with a complicated root shape without resistance. The sponge (continuous porous body) made of natural cellulose, natural rubber, synthetic rubber, or synthetic resin deforms and adapts, so it is possible to clean even the root root depression. In addition, the material of the interdental cleaning portion and the shaft portion having shape resilience and elasticity makes it possible to prevent deformation and fracture due to metal fatigue and the like, unlike a conventional interdental brush.

This tooth-tooth cleaning tool cleans cases with swelling due to gingival inflammation and molars that cannot be seen directly, especially the distal part of the posterior molars and the interdental area. Even if there is a restriction on the insertion direction of the part, the smoothly rounded tip of the interdental cleaning sponge should be inserted into the ない -side gingival-side interdental space or lingual side from any reasonable direction. (Palatal side) Positioned in the gingival-side interdental space, 軽 Gently press in the tongue direction, reach the target site, and hold it to enable plaque control. In addition to helping to prevent damage to the papillae and gingiva, the interdental cleaning sponge and the cleaning tip itself, or the joint between the mouth cleaning part and the body, are not subjected to unnecessary pressure to prevent damage and durability. It is possible to above.

In the third invention, in general, in the case of large retraction of the interdental papillae, the shape of the interdrum space is a triangle in which the apex is the contact point of both adjacent teeth, and the base is the end face of the adjacent periodontal pocket bottom. Since it has an outer shape, a relatively hard and highly compressible natural fibrous material is arranged radially from the center of the cross-sectional form similar to this shape to the vertex of the triangular shaped interdrum space, An interdental cleaning sponge made of sponge (continuous porous body) made of natural rubber, synthetic rubber, or synthetic resin, or the interdental cleaning sponge is a 0.1 mm to 2 mm plate-shaped piece. The center of the cleaned interdental cleaning fin has the same angle The sponge between teeth is continuously glued or welded in a rosary shape to the shaft that has appropriate elasticity, shape resilience, and flexibility. It is a tooth cleaning tool that can be rotated from 0 ° left and right to 45 ° left and right, and has a tooth cleaning sponge that fits into the holding part of the manual tooth cleaning tool or the slide shaft of the electric tool that slides. is there.

With this interdental cleaning tool, the holder of the manual interdental cleaning tool and the electric tool are simply inserted into the interdental area from any insertion angle and direction, and the mesio-distal free gingiva of the adjacent tooth is set with the tooth contact point as the apex. The interdental cleaning sponge is automatically rotated and fitted to an angle suitable for the isosceles triangular interdental space with the bottom as the base, and inserted so as to fill the interdental space without any gap. In this type of interdental cleaning sponge, if the outer shape of the interdental cleaning fin, which is a plate-shaped piece from the front end to the rear end in a tapered shape, is gradually increased, the operation for inserting the interdental portion becomes easier. become. In addition, due to the difference in the compressibility of the interdental cleaning fins that are closely pressed into the interdrum space, a relatively continuous sponge or other special continuous porous body is formed between the adjacent teeth and the adjacent teeth. It makes it possible to clean the plaque at the point of contact.

A fourth aspect of the present invention is an interdental cleaning tool provided with an interdental cleaning sponge having a spiral groove formed in a long axis surface of the interdental cleaning sponge according to the first invention. Electric interdental cleaning The helical groove on the long axis surface due to the rotational movement of the shaft of the instrument only allows plaque to be extracted and can be intentionally discharged in a certain direction on the left or lingual side. Rather, by changing the rotational movement direction of the electric tooth cleaning tool shaft as needed, the screw-shaped groove exerts propulsive force, so that the interdental cleaning sponge can enter the narrowed interdrum space. In addition to making it easier, driving the electric tooth cleaning tool in reverse rotation will help pull out the tooth cleaning sponge easily.

According to a fifth aspect of the present invention, the cleaning sponge portion according to the first aspect has a star-shaped cross-section. (Shade shape), gear shape, or star shape (shade shape), the shaft length is set so that the top of the protruding portion of the gear shape is spirally deformed in a constant spiral in the axial rotation direction. This is an interdental cleaning tool in which a plurality of grooves are formed parallel to the axial direction or in multiple spirals.

When the interdental cleaning device is inserted into the interdental portion and rotated, if it has a shape that has a groove parallel to the longitudinal axis, it will have a star shape (a star shape), a gear shape, or a star shape. With the cross-sectional shape in which the top of the protruding portion of the tooth (shape) and gear shape is constantly spirally deformed in the axial rotation direction, plaque is gathered at the bottom of the groove, and multiple grooves are formed in multiple spirals In the shape that forms, the collected plaque further extrudes plaque by the rotational movement of the electric interdental cleaning instrument shaft, and at the same time, is intentionally discharged in a certain direction on the contralateral or lingual side. It becomes possible. In addition, by changing the rotational movement direction of the shaft portion of the electric interdental cleaning tool as needed, the gap between the interdrum gaps narrowed by the multi-spiral (multi-screw) propulsion force as in the third invention. The interdental cleaning sponge facilitates intrusion of the interdental cleaning sponge, and driving the electric interdental cleaning tool in a reverse rotation can easily assist in pulling out the interdental cleaning sponge. The cleaning sponge has a star-shaped (star-shaped), gear-shaped, or star-shaped (star-shaped), and a cross-sectional shape with the apex of the gear-shaped protrusion rotated and deformed constantly in the axial rotation direction. 1 to 2 mm highly compressible sponge (continuous porous body) such as natural fiber, natural rubber, synthetic rubber, or synthetic resin, each having the same compressibility or different compressibility Pieces are randomly offset Or beaded or welded to the shaft in a bead shape so that it is displaced at a fixed angle to the axis (a plurality of spiral grooves are formed stepwise in the axial direction). It is a cleaning sponge between teeth. Simply insert and hold the tooth cleaning sponge in the interdental area and hold it. The apexes of the star-shaped and gear-shaped projections arranged randomly in the shaft rotation direction are plaque. And store plaque on its base. In addition, the interdental cleaning unit arranged so as to be displaced at a fixed angle to the shaft (shape a plurality of helical grooves in a stepwise fashion in the axial direction ^) uses the rotating force of the electric interdental cleaning tool. In addition to not only enabling plaque to be intentionally discharged in a certain direction on the 頰 or lingual side, as in the third and fourth inventions, it is also possible to remove plaque in multiple spirals (multiple spirals). In addition to facilitating penetration of the interdental cleaning sponge into the interdrum space narrowed by the propulsion force, driving the electric interdental cleaning tool in reverse rotation will help pull out the interdental cleaning sponge easily. .

The seventh invention is characterized in that a plurality of grooves are formed in a direction perpendicular to the axial direction on the surface of the sponge portion having various cross-sectional shapes according to the first invention and the fourth invention, or the outer peripheral shape is polygonal or circular. Interdental cleaning sponge, characterized in that it is provided with an interdental cleaning sponge in which pieces having the same compressibility or different compressibility are arranged in a beaded shape on a shaft portion, each of which is a force-up type. It is a device. The interdental cleaning sponge is slid in the axial direction using an electric interdental cleaning tool or a hand tool to trap plaque inside the groove or on the inner surface of the cup portion, and further to the 頰 or lingual side. Can be discharged to

According to an eighth aspect of the present invention, the sponge for cleaning teeth between teeth according to the first to the fourth aspects of the present invention is made of natural fiber and natural rubber so that the front end, the center and the rear end have different compressibility. Whether the sponge (continuous porous body) of synthetic rubber, synthetic resin, or the like is multiplex-moulded by transition or by site, the tip piece, the rear piece, and the center of the fifth and sixth inventions Is a sponge (continuous porous body) made of natural fiber, natural rubber, synthetic rubber, or synthetic resin with different compressibility. —For example, the sponge (continuous porous body) made of natural fiber, natural rubber, synthetic rubber, or synthetic resin that is relatively compressible at the front and rear ends and relatively soft at the center, and relatively soft at the center. With this configuration, when inserting the interdental part, the frictional resistance of the relatively hard parts at both ends can be sensed with the feel of a finger, and the cleaning sponge can be accurately inserted into the interdental part without using a mirror. You can check. In addition, a relatively soft part or a soft piece in the central part is well adapted to a root indentation and enhances plaque removal efficiency.

According to a ninth aspect of the present invention, the cross-sectional shape of the resin whose surface is made of resin, metal, or the like constituting the shaft portion according to the first invention is circular, polygonal, or star-shaped, or the vertical cross-sectional shape is changed. An interdental cleaning device characterized in that the shape of a brush portion obtained by electrostatically flocking a pile of a single length of nylon or the like on the shaft portion is freely reproduced by forming a corrugated or uneven shape. .

Such a shape of the shaft portion allows the pile of single length nylon or the like to reproduce the outer shape of the brush portion subjected to electrostatic flocking processing in a similar shape. Applicable to the tooth surface, gingiva and gingival sulcus, and efficiently remove and clean plaque.

According to a tenth aspect of the present invention, in addition to the first aspect of the ninth aspect, when a pile such as a nipple is electrostatically implanted on a shaft portion, a portion to be implanted is masked in advance and electrostatic implantation is performed. It is a tooth cleaning device characterized by being processed. Since the site where hair is implanted can be designed freely, it is possible to freely reproduce the optimal hair implantation shape according to brushing methods such as spiral, side-by-side rotation, sliding, or rotating slide interlocking.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 3 to 9 show an example of the embodiment of the present invention. In the drawings, the portions denoted by the same reference numerals as those in the drawings represent the same items, and are basically used when actually used in the oral cavity. The configuration is the same as the conventional one shown in Figs. 1 and 2, but the features of this example are the electric tooth cleaning tool shown in Fig. 1 and the manual tooth brush shown in Fig. 2. The point is that the cleaning brush portion made of metal twisted wire and nap fiber is made of a special continuous porous material such as a sponge and a flexible metal or resin having an appropriate elasticity and shape resilience. As shown in FIG. 1, the interdental cleaning sponge part 1 adhered or welded to the shaft part 2 of the electric interdental cleaning tool is inserted into the interdental part, and the electric interdental cleaning tool holding part 11 is maintained at that position. The plaque in the interdental area is pressed against the sponge surface in various shapes and the tooth surface, gingiva and gingival sulcus by the rotary motion 21, reciprocating motion 23, or rotary slide motion of the natural fiber It is automatically removed and cleaned by fine irregularities on the surface of sponge (continuous porous body) such as element, natural rubber, synthetic rubber, or synthetic resin. In addition, when the sponge for cleaning between teeth shown in Fig. 3 is inserted into the interdental area while the electric tooth cleaning device is in operation, the sponge tip 1a is covered with a sponge that has elasticity. To prevent damage to the margins and papillary gingiva when inserted into the part, the shaft 2 made of resin or metal, etc. that has both appropriate elasticity, shape resilience, and flexibility If there is a restriction on the shaft insertion direction with respect to the gap, the interdental cleaning sponge 1 together with the shaft 2 is deformed as shown in Fig. 4 with appropriate elasticity, so that a maze-like interdental part with a complex root shape is formed. Not only can it be inserted without any resistance, but it can also be deformed by the compressible elasticity of the special continuous porous body, so that it is possible to clean even the root root depression. In addition, due to the material of the interdental cleaning part and the shaft part that have shape resilience and elasticity, deformation and fracture due to metal fatigue and the like are different from the conventional interdental brush Is prevented. In addition, the sponge part 2 as shown in Fig. 7 is combined with a hard sponge part 7b and a soft sponge part 7a that are similar to the tongue-shaped tongue-shaped tongue-shaped cross-section and connected in a bead shape. The continuous sponge-shaped inter-tooth gap sponge 7 is rotated in the axial direction by the rotation stopper 3 from left and right 0 ° to left and right 4 5 ° freely repetitive operation 2 2 When the cleaning sponge fixed to the interdental papillary retraction site is inserted into the interdental papillary retraction site, the apex of the triangle is used as the contact point between the adjacent teeth. Then, the cleaning sponge is automatically rotated to an angle suitable for the shape of a triangle having both ends at the bottom of the adjacent periodontal pocket, and the cleaning sponge is guided to the interdrum space. Further, since the continuous sponge-shaped interdental cleaning sponge 7 is composed of the soft sponge portion 7a and the hard sponge portion 7b, the hard sponge portion 7b is located inside the adjacent periodontal pocket bottom. Remove and clean the tooth slope. Needless to say, this mechanism is similarly useful in an electric interdental cleaning device that slides the shaft portion 2. In addition, as shown in Fig. 3, the interdental cleaning sponge, consisting of a hard sponge 24 at the front and rear ends and a soft sponge 25 at the center, has a narrowed interdental tooth, as shown in Fig. 4. When inserted into the gap, the frictional resistance of the relatively hard hard sponge 24 at both ends is sensed with the feel of a finger, and the cleaning sponge is accurately inserted into the interdental area without using a mirror or the like. Confirm, you can. In addition, the relatively soft soft sponge 25 at the center is well fitted to the tooth (root) cross-section depression 34 and improves plaque removal efficiency. As shown in Figs. 3, 5, 6, 6, 7, 8 and 9, the periphery of the tip of the shaft, such as resin or metal, which has both appropriate elasticity and shape resilience and flexibility. A sponge (continuous porous body) of highly compressible natural fibrous material, natural rubber, synthetic rubber, or synthetic resin, which is deformed in various forms, is spliced or welded between teeth. Alternatively, it can be used for the movement axis of an electric interdental cleaning device that generates a rotating slide motion or a manual interdental cleaning device. If used, the interdental cleaning sponge shown in Fig. 3, Fig. 6, and Fig. 9 will extract dental plaque and simultaneously rotate the tooth according to the direction of rotation of the shaft part 2 by rotating the tooth to the right or left side. While being discharged to the lingual side, the interdental cleaning sponge shown in Figs. 6 and 9 has a multiple spiral (multiple screw), and the interdental cleaning sponge shown in Fig. 3 has a narrow (screw) propulsion force. In addition to facilitating penetration of the interdental cleaning sponge into the formed interdental space, driving the electric interdental cleaning tool in reverse rotation will help pull out the interdental cleaning sponge easily. In addition, the interdental cleaning sponge of the form shown in FIG. 8 is not capable of cleaning while storing the plaque generated in the reciprocating motion 23 in the continuous force type interdental cleaning sponge recess 8b. Pleasure can be reduced. Naturally, the shape of the interdental cleaning sponge shown in Fig. 3, Fig. 5, Fig. 6, Fig. 7, Fig. 8, and Fig. 9 can increase the cleaning ability even if it is used alone. I do. In the deformed invention, as shown in FIG. 10, a fiber brush 26 a made of a natural fiber, a natural rubber, a synthetic rubber, or a synthetic resin having a moderate elasticity and a high compressibility is used. The fiber brush 26 b is made of resin or metal, etc., which has appropriate elasticity, shape resilience, and flexibility connected to the slide shaft so that it has a cylindrical or polygonal cylindrical shape with a smooth roundness. Electrodeposited, glued or welded to the shaft 2 to prevent damage to the margin and papillary gingiva when inserted into the interdental area, and to use the を -side gingival-side interdrum space as a guide The axial direction of the firer brush, which is determined by the direction of insertion of the interdental cleaning device or electric interdental cleaning device into the mouth, is deformed by the appropriate elasticity of the shaft, shape resilience, and flexibility, and the interdrum gap At the same time as leading to the tongue-winning direction When the fiber brush is moved in a sliding motion, a rotating motion, or a rotating sliding motion, the shaft portion of the interdigital tooth gap is merely inserted into a maze-like interdental space having a complicated root shape. It adapts and deforms according to the complex anatomical morphology. Similarly, the fiber brush is pressed against the tooth surface of the interdental area and the gingival gingival sulcus by excessively deforming, removing and cleaning the teeth, as well as reshaping the shaft with elasticity and elasticity. The material prevents deformation and breakage.

In addition, the sponge brush shown in Fig. 1 is divided into a shaft section thin (stress deformation) section 40 and a thick section like the sponge brush shown in Fig. 11 to form a shaft section thin (stress deformation) section. Since 0 undergoes more stress deformation, — it will be deformed by the external force, and it is possible to deform the entire brush at any set location. If the present invention is further developed, as shown in Fig. 12, a shaft cross-section detail 37 and a shaft cross-section thick portion 38 are provided in the shaft vertical cross-section, and an equal-length nipper pile 39 is subjected to electrostatic flocking processing. For example, it is possible to set an arbitrary brush outer shape in which the outer shape of the brush portion is similar to the shaft portion. In addition, by setting the shaft cross section 41 to a star shape or a polygon as shown in Fig. 13, the cross section of the brush section is also formed by an equal length nylon pile 39 that is also electrostatically flocking. Can be set arbitrarily. Also, as shown in Fig. 14, the brushing position of the brush part is the masking part 35 except for the flocking processing of the shaft part 2 and the electrostatic flocking processing is applied to the adhesive application part 36. Since the flocking position can be set, the entire flocking flow can be set freely, such as spiral or point (dot).

In addition, the overall shape and shaft of the present invention and the material of sponge (continuous porous body) such as natural fiber, natural rubber, synthetic rubber, or synthetic resin with high compressibility, and the method of bonding or welding, The mechanism of the interdental cleaning device, such as a sliding motion, a rotating motion, or a rotating sliding motion, and the shape of the manual interdental cleaning device are not limited to the above-described illustrated examples, but are essential to the present invention. Of course, various changes can be made without departing from the spirit of the invention.
