Description
本発明は歯垢検出機能付き歯ブラシシステムに関する。 The present invention relates to a toothbrush system with a plaque detection function.
従来から、う蝕や歯周疾患は、歯垢中に存在する細菌に起因する感染症と考えられており、歯垢の除去が口腔の健康のために非常に重要であることが知られているが、歯垢は肉眼的に容易に識別しにくく、その付着部位及びその程度を正確に確認することが困難である。 Traditionally, caries and periodontal diseases are considered to be infections caused by bacteria present in plaque, and it is known that removal of plaque is very important for oral health. However, it is difficult to identify plaque easily with the naked eye, and it is difficult to accurately check the adhesion site and the degree thereof.
そこで、付着した歯垢を明らかにするために、歯垢を色素含有の歯垢染色剤で赤色に染色し、その存在部位を顕示させるのが一般的であるが、その赤色は、容易に除去し難く、通常の歯ブラシによる歯磨き行為では十分に除去できず、歯間部、歯肉、唇等に残存する為、不快感を伴うという問題があった。 Therefore, in order to clarify the adhering plaque, it is common to stain the plaque in red with a pigment-containing plaque stain and reveal the location of the plaque, but the red is easily removed. However, it cannot be removed sufficiently by brushing with a normal toothbrush, and it remains in the interdental region, gums, lips, etc., causing uncomfortable feeling.
ここで、従来の歯垢を検出する方法に関しては、例えば口腔内に光を照射する器具（特許文献１）や、特定の光を照射して光のみで歯垢を検出する技術（特許文献２）等も提案されている。 Here, with regard to a conventional method for detecting plaque, for example, a device that irradiates light into the oral cavity (Patent Document 1), or a technique that irradiates specific light and detects plaque only by light (Patent Document 2). ) Etc. are also proposed.
しかしながら、上記の従来の技術では、歯ブラシを使って歯垢を除去する場合に、使用者が歯垢を目視により確認しなければならず、必ずしも確実に歯垢を除去できなかったり、また、歯磨きの前後にどの程度の歯垢が残っているかを正確に把握できなかったりする問題があった。 However, in the conventional technique described above, when removing plaque using a toothbrush, the user must visually check the plaque, and the plaque cannot always be removed with certainty. There is a problem that it is impossible to accurately grasp how much plaque remains before and after.
そこで、本発明は、歯垢染色剤を用いなくても、光源により可視化された歯垢を前記イメージセンサで検出して数値化し、歯垢の量を測定することができる歯垢検出機能付き歯ブラシシステムを提供することを目的とする。 Therefore, the present invention provides a toothbrush with a plaque detection function capable of measuring the amount of plaque by detecting and quantifying the plaque visualized by a light source without using a plaque stain. The purpose is to provide a system.

When the toothbrush is an electric toothbrush provided with an overpressure stopper and the head portion of the toothbrush moves back and forth in the length direction of the toothbrush, the movement of the head portion is suppressed by the overpressure stopper , A toothbrush system with a plaque detection function is provided.
上記本発明の歯垢検出機能付き歯ブラシシステムにおいては、前記光源が前記歯ブラシに内蔵されていること、が好ましい。 In the toothbrush system with a plaque detection function of the present invention, it is preferable that the light source is incorporated in the toothbrush.
本発明の歯垢検出機能付き歯ブラシシステムによれば、光源により可視化された歯垢を前記イメージセンサで検出して数値化し、歯垢の量を測定することができる。これにより、歯ブラシを使って歯垢を除去する場合に、歯垢の量や位置を確実に把握することができるため、歯垢の除去が容易となったり、歯科医師による歯磨きの指導の方針を立て易くなったりするという効果がある。 According to the toothbrush system with a plaque detection function of the present invention, the plaque visualized by the light source is detected and digitized by the image sensor, and the amount of plaque can be measured. As a result, when removing the plaque using a toothbrush, the amount and position of the plaque can be reliably grasped, which makes it easier to remove the plaque and provides a guideline for brushing instructions by the dentist. There is an effect that it is easy to stand.
以下、本発明の歯垢検出機能付き歯ブラシシステムの代表的な実施形態について、図面を参照しながら説明するが、本発明はこれらのみに限定されるものではない。 Hereinafter, although typical embodiment of the toothbrush system with a plaque detection function of the present invention is described, referring to drawings, the present invention is not limited only to these.
図１は、本発明の歯垢検出機能付き歯ブラシシステムの代表的な実施形態を示す模式図である。本実施形態の歯垢検出機能付き歯ブラシシステム１は、グリップ部２、ブラシ４が設けられたヘッド部６、グリップ部２とヘッド部６とを接続する柄部８、及びヘッド部６に設けられたイメージセンサ１０、を含む歯ブラシ１４と、発光素子を有する光源１２と、を具備する。 FIG. 1 is a schematic view showing a typical embodiment of a toothbrush system with a plaque detection function of the present invention. The toothbrush system 1 with the plaque detection function of the present embodiment is provided in the grip portion 2, the head portion 6 provided with the brush 4, the handle portion 8 that connects the grip portion 2 and the head portion 6, and the head portion 6. A toothbrush 14 including the image sensor 10 and a light source 12 having a light emitting element.
光源１２は歯ブラシ１４に内蔵されており、光源１２により光を照射されて可視化された歯垢はイメージセンサ１０で検出して数値化され、携帯端末１６によって歯垢の量を検知することができる。例えば、２５０〜５００ｎｍの波長の紫外線を照射するブラックライトを用い、可視化された歯垢をＶＧＡ（６４０×４８０）の低画素センサからなるイメージセンサ１０で検出すればよい。本実施形態では、光源１２とイメージセンサ１０は互いに近傍に設けられている。 The light source 12 is built in the toothbrush 14, and the plaque visualized by being irradiated with light from the light source 12 is detected and digitized by the image sensor 10, and the amount of plaque can be detected by the portable terminal 16. . For example, a black light that irradiates ultraviolet rays having a wavelength of 250 to 500 nm may be used, and the visualized dental plaque may be detected by the image sensor 10 including a low pixel sensor of VGA (640 × 480). In the present embodiment, the light source 12 and the image sensor 10 are provided in the vicinity of each other.
本実施形態においては、Ｗｉ−Ｆｉ又はＢｒｕｅｔｏｏｔｈ（登録商標）等の無線システムによって、イメージセンサ１０と携帯端末１６が接続されており、この携帯端末１６で所定期間の歯垢の量や歯磨き前後の歯垢の量を記録することができる。このような記録ができれば、携帯端末１６を通じて使用者に歯磨きの指導や診断をしたり、歯科医院へ行くことを勧めたりすることができる。 In the present embodiment, the image sensor 10 and the portable terminal 16 are connected by a wireless system such as Wi-Fi or Bluetooth (registered trademark). The amount of plaque can be recorded. If such a record can be made, the user can be instructed and diagnosed with brushing teeth through the portable terminal 16, or can be encouraged to go to the dental clinic.
ここで、歯垢は、一般的に、口腔内細菌が、歯面上のタンパク被膜に付着する初期状態を経て、菌体外多糖類を形成後、多種多様な常在菌が、更に、付着・定着して、増加するため、経時的に、その構造・菌種が変化することが知られている。したがって、本発明における歯垢とは、時間の経過に制限されず、歯の表面に付着・定着し、歯石状の物も含んだ、細菌や細菌の生産物からなる複合体の総称である。 Here, plaque is generally in an initial state where oral bacteria adhere to the protein coating on the tooth surface, and after forming an extracellular polysaccharide, a wide variety of resident bacteria further adhere to it.・ It is known that the structure and bacterial species change over time because it settles and increases. Therefore, the plaque in the present invention is not limited by the passage of time, but is a general term for a complex composed of bacteria and bacterial products that adheres and settles on the tooth surface and includes calculus.
また、光源１２により口腔内の歯に照射される光は、２５０〜５００ｎｍの範囲内に波長を有するものが用いられる。前記範囲内の波長を有する光を照射可能であれば、光源は種類を問わない。例えば、２５０〜５００ｎｍの範囲内の波長を有する光を放射する発光ダイオード（ＬＥＤ）やブラックライト等を用いることができる。 Moreover, the light with which a light source 12 irradiates the teeth in the oral cavity has a wavelength in the range of 250 to 500 nm. The type of light source is not limited as long as it can irradiate light having a wavelength within the above range. For example, a light emitting diode (LED) that emits light having a wavelength in the range of 250 to 500 nm, a black light, or the like can be used.
その他にも、例えばキセノンランプ、キセノンフラッシュランプ、メタルハライドランプ、ホローカソードランプ等を用いることもできる。これらのランプから出射される光が広範囲の波長を有する場合、２５０〜５００ｎｍの範囲内の波長の光を選択的に透過させるバンドパスフィルターを用いることにより、又は、ハイパスフィルターとローパスフィルターを組み合わせたものを用いることにより、２５０〜５００ｎｍの範囲内の波長の光を選択的に透過させてもよい。この場合、容易性の点でバンドパスフィルターを用いるのが好ましい。 In addition, for example, a xenon lamp, a xenon flash lamp, a metal halide lamp, a hollow cathode lamp, or the like can be used. When the light emitted from these lamps has a wide range of wavelengths, a bandpass filter that selectively transmits light having a wavelength in the range of 250 to 500 nm is used, or a high-pass filter and a low-pass filter are combined. By using one, light having a wavelength in the range of 250 to 500 nm may be selectively transmitted. In this case, it is preferable to use a bandpass filter in terms of ease.
また、発光素子から放射される光の波長が、２５０〜５００ｎｍの範囲から外れる場合は、この発光素子と前記バンドパスフィルターを組み合わせて用いてもよい。 Moreover, when the wavelength of the light radiated | emitted from a light emitting element remove | deviates from the range of 250-500 nm, you may use combining this light emitting element and the said band pass filter.
前記ローパスフィルターとしては、例えば、５００ｎｍ以下の波長の光を透過するものが用いられる。前記ハイパスフィルターとしては、例えば、２５０ｎｍ以上の波長の光を透過するものが用いられる。 As the low-pass filter, for example, a filter that transmits light having a wavelength of 500 nm or less is used. As the high-pass filter, for example, a filter that transmits light having a wavelength of 250 nm or more is used.
ここで、図１に示す歯垢検出機能付き歯ブラシシステム１には、過圧ストッパー１８及び押付け防止センサー２０が設けられている。過圧ストッパー１８は、使用者が歯ブラシ１４のブラシ４を歯に強い力で押し付け過ぎた場合に、歯磨きの動きをストップさせるためのものである。また、押付け防止センサー２０は、使用者が歯ブラシ１４のブラシ４を歯に強い力で押し付け過ぎた場合に、ランプを点灯させて使用者の注意を喚起するものである。 Here, the toothbrush system 1 with the plaque detection function shown in FIG. 1 is provided with an overpressure stopper 18 and a pressing prevention sensor 20. The overpressure stopper 18 is for stopping the movement of toothpaste when the user presses the brush 4 of the toothbrush 14 against the teeth with a strong force. In addition, the pressing prevention sensor 20 is to turn on the lamp to alert the user when the user presses the brush 4 of the toothbrush 14 with a strong force against the teeth.
以上、本発明の代表的な実施形態としての歯垢検出機能付き歯ブラシシステム１を説明したが、本発明の技術的思想を具備するのを前提に種々の設計変更が可能であり、それら設計変更をした態様も当然に本発明の技術的範囲に含まれる。 As described above, the toothbrush system 1 with a plaque detection function as a representative embodiment of the present invention has been described. However, various design changes are possible on the assumption that the technical idea of the present invention is provided, and those design changes are possible. Naturally, the above-described embodiments are also included in the technical scope of the present invention.
例えば、従来の電動歯ブラシのように、ヘッド部６が歯ブラシ１４の長さ方向において前後に動く機能を有していてもよい。この場合、上記の過圧ストッパー１８によってヘッド部６の動きが抑制される構成を有していてもよい。また、本実施形態によれば、基本的に歯垢染色剤を用いなくてもよいが、歯垢染色剤を用いてもよい。 For example, like the conventional electric toothbrush, the head unit 6 may have a function of moving back and forth in the length direction of the toothbrush 14. In this case, you may have the structure by which movement of the head part 6 is suppressed by said overpressure stopper 18. In FIG. Further, according to the present embodiment, it is not necessary to basically use a plaque stain, but a plaque stain may be used.
従来は、歯科医師による治療が必要なため高額な費用がかかったり、診断に時間がかかり治療まで１週間〜数週間かかったり、異常があれば歯医者へ行かなければならないという問題があったが、本発明によれば、歯科衛生士による歯垢除去も可能であり費用が安くて済んだり、自宅で歯垢の量を把握して使用者自ら１次診断が可能であり、かつその情報を歯科医師が活用すれば短時間で治療・診断（クリーニングを含む。）を終えることができる。また、使用者は、自宅で気軽に診断することができ、予防歯科観点からも好適である。 In the past, treatment by a dentist was necessary, so it was expensive, it took a long time to diagnose, and it took a week to several weeks. If there was an abnormality, there was a problem that you had to go to a dentist. According to the present invention, dental hygienist can remove the plaque and the cost is low, or the user can make a primary diagnosis by grasping the amount of plaque at home, and the information is stored in the dentist. If used by a doctor, treatment and diagnosis (including cleaning) can be completed in a short time. In addition, the user can easily make a diagnosis at home, which is preferable from the viewpoint of preventive dentistry.
