以下、本発明を図面に示す形態に基づき説明する。ただし本発明はこれら形態に限定されるものではない。なお、以下に説明する歯肉溝滲出液の採取用具は小さい器具であるので、分かり易さのため、各図では形状を誇張、変形して表すことがある。   Hereinafter, the present invention will be described based on embodiments shown in the drawings. However, the present invention is not limited to these forms. Note that the gingival crevice exudate collection tool described below is a small instrument, and for ease of understanding, the shape may be exaggerated and deformed in each figure.

図１は１つの形態にかかる歯肉溝滲出液の採取用具１０（以下、「採取用具１０」と記載することがある。）の斜視図である。図１からわかるように、採取用具１０は全体として中空の筒状であり、その長手方向一方側である採取部１０ａ及びその他方側である保持部１０ｂを有して構成されている。そのために採取用具１０は筒状体１１及び樹脂１２を備えている。筒状体１１及び樹脂１２については、採取用具１０の製造方法の一例を説明する際に合わせてその形態を説明する。ここでは、始めに採取用具１０に具備される採取部１０ａ及び保持部１０ｂについて説明する。   FIG. 1 is a perspective view of a gingival crevicular fluid collection tool 10 (hereinafter sometimes referred to as “collection tool 10”) according to one embodiment. As can be seen from FIG. 1, the sampling tool 10 has a hollow cylindrical shape as a whole, and includes a sampling portion 10a on one side in the longitudinal direction and a holding portion 10b on the other side. For this purpose, the collection tool 10 includes a cylindrical body 11 and a resin 12. The cylindrical body 11 and the resin 12 will be described in conjunction with an example of the method for manufacturing the collection tool 10. Here, first, the collection unit 10a and the holding unit 10b included in the collection tool 10 will be described.

採取部１０ａは歯肉溝滲出液を採取する部位であり中空状とされている。一方保持部１０ｂは、樹脂１２等により固められており中空の内側がこの樹脂などにより埋められており、ここでは歯肉溝滲出液を採取しない構造とされている。ただし、このように筒状体１１が筒状体であることを維持することができれば、必ずしも中空の内側を埋める必要はなくここが中空であってよく、樹脂１２等で埋められている必要はない。ただし、このように樹脂１２等により固められることで、この部分（保持部１０ｂ）を使用者がピンセットで摘む等して採取用具１０の取り回しが容易になる。また後で説明するように、歯肉溝滲出液の採取用具１０はシート状の材料が筒状に巻かれることにより形成されているので、樹脂１２等で固められることにより当該巻かれた状態を維持（展開してしまわない。）することができる。   The collection part 10a is a part that collects the gingival crevicular fluid and has a hollow shape. On the other hand, the holding portion 10b is hardened with a resin 12 or the like, and a hollow inner side is filled with this resin or the like, and here, the gingival crevicular exudate is not collected. However, if it can be maintained that the cylindrical body 11 is a cylindrical body in this way, it is not always necessary to fill the inside of the hollow, and this may be hollow, and it is necessary to be filled with the resin 12 or the like. Absent. However, by being hardened with the resin 12 or the like in this manner, the user can easily handle the collection tool 10 by picking this portion (holding portion 10b) with tweezers. Further, as will be described later, the gingival crevicular fluid collection tool 10 is formed by winding a sheet-like material into a cylindrical shape, so that the wound state is maintained by being hardened with resin 12 or the like. (Do not expand.)

採取用具１０はさらに次のような特徴を有していることが好ましい。すなわち、採取用具１０は、筒状（筒状体１１）の壁部はその厚さ方向において、薄い壁が複数重ねられるようにしてなる部位を具備している。そして、採取部１０ａ及び保持部１０ｂの少なくとも一方では、重ねられている薄い壁の数が筒状の長手方向中央に対して、少なくなるように構成されていることが好ましい。そして最端部では当該薄い壁が１枚となる部位があってもよい。
より好ましくは少なくとも採取部１０ａにおいて当該重なりの数が少なくされている。これにより採取部１０ａの先端がより細くなり、歯肉溝に採取部１０ａを差し入れたときに患者の負担を減らすことができる。
以上のような構造により簡易な構造であるとともに、後述するように作製し易いし採取用具１０とすることが可能である。また採取用具１０は筒状であること、及び、この筒状では複数の薄い壁が複数重ねられていることから折れ難く扱い易いものとなる。特に限定されることはないが、最も重ねられている部位において３重〜７重であることが好ましい。 The collection tool 10 preferably further has the following characteristics. That is, the sampling tool 10 includes a portion in which a plurality of thin walls are stacked in the thickness direction of the cylindrical wall portion (tubular body 11). And at least one of the collection part 10a and the holding | maintenance part 10b is preferably comprised so that the number of the piled thin walls may decrease with respect to a cylindrical longitudinal direction center. And there may be a part where the thin wall becomes one sheet at the extreme end.
More preferably, the number of overlaps is reduced at least in the collection part 10a. Thereby, the front-end | tip of the extraction | collection part 10a becomes thinner, and a patient's burden can be reduced when the extraction | collection part 10a is inserted in a gingival crevice.
The structure as described above is a simple structure, and is easy to manufacture as described later, and the sampling tool 10 can be obtained. Further, the sampling tool 10 is cylindrical, and in this cylindrical shape, a plurality of thin walls are stacked, so that it is difficult to break and easy to handle. Although not particularly limited, it is preferably triple to sevenfold in the most overlapped portion.

採取用具１０は、その性質上、その直径は小さくするとともに、取り扱いの観点からはある程度の長さがあることが好ましい。従って、図１に示したように、採取用具１０の長手方向全長をＡとし、採取部１０ａの長手方向の大きさをＢ、採取部１０ａの外周の直径の最大値をＣとしたとき、Ａは２５ｍｍ以上７０ｍｍ以下、Ｂは８ｍｍ以上１５ｍｍ以下、及びＣは０．８ｍｍ以上１．５ｍｍ以下とすることが好ましい。
全長Ａが２５ｍｍより短くなると取り扱いし難くなる虞があり、全長Ａが７０ｍｍより長くなると取り扱い中に折れる可能性が高くなる。
採取部１０ａの長手方向の大きさＢが８ｍｍより小さくなると、場合によっては採取される歯肉溝滲出液の量が不足する虞があり、Ｂが１５ｍｍより大きいと取り扱い中に折れる可能性が高くなる。
採取部１０ａの外周の直径の最大値Ｃが０．８ｍｍより小さいと場合によっては歯肉溝滲出液の量が不足したり、取り扱い中に折れる可能性が高くなり、Ｃが１．５ｍｍより大きいと採取部１０ａを歯肉溝に挿入した際に患者が違和感や痛みを感じる可能性が高まる。
さらに、採取部１０ａにおいて、中空であるその内径は一定であることが好ましい。 The collection tool 10 preferably has a small diameter and a certain length from the viewpoint of handling due to its nature. Therefore, as shown in FIG. 1, when the total length in the longitudinal direction of the sampling tool 10 is A, the size in the longitudinal direction of the sampling portion 10a is B, and the maximum value of the outer diameter of the sampling portion 10a is C, A Is preferably 25 mm to 70 mm, B is preferably 8 mm to 15 mm, and C is preferably 0.8 mm to 1.5 mm.
If the total length A is shorter than 25 mm, it may be difficult to handle, and if the total length A is longer than 70 mm, the possibility of breaking during handling increases.
If the length B in the longitudinal direction of the collection part 10a is smaller than 8 mm, the amount of gingival crevicular fluid collected may be insufficient in some cases, and if B is larger than 15 mm, the possibility of breaking during handling increases. .
If the maximum diameter C of the outer circumference of the sampling part 10a is smaller than 0.8 mm, the amount of gingival crevice exudate may be insufficient or may break during handling, and if C is larger than 1.5 mm When the collection part 10a is inserted into the gingival sulcus, the patient is likely to feel discomfort and pain.
Furthermore, in the collection part 10a, it is preferable that the hollow internal diameter is constant.

次に本形態の採取用具１０の製造方法について説明する。図２及び図３に説明のための図を示した。図２（ａ）は筒状体１１が展開された状態の図、図２（ｂ）は筒状体１１を巻き取る場面を表した図、図３（ａ）は筒状体１１が芯棒２０に巻かれた図、図３（ｂ）は筒状体１１から芯棒２０を抜き取った状態の図、及び図３（ｃ）は保持部１０ｂが形成された状態の図をそれぞれ表している。   Next, the manufacturing method of the collection tool 10 of this form is demonstrated. FIG. 2 and FIG. 3 are diagrams for explanation. 2A is a diagram showing a state in which the cylindrical body 11 is unfolded, FIG. 2B is a diagram showing a scene where the cylindrical body 11 is wound up, and FIG. 3A is a diagram illustrating the cylindrical body 11 being a core rod. FIG. 3B shows a state in which the core rod 20 has been removed from the cylindrical body 11, and FIG. 3C shows a state in which the holding portion 10b has been formed. .

図２（ａ）からわかるように、本形態で筒状体１１は等脚台形のシート状である。筒状体１１の材料としては、特に制限はなく、例えば、和紙、パルプ紙等の他、不敷布を用いた繊維、糊で固めた布を併用することもできる。
このような巻かれる前の展開された状態の筒状体１１に対して、図２（ｂ）に示したように筒状体１１の台形である下底に沿って平行に芯棒２０を配置する。この芯棒２０の外周の直径は完成する採取用具１０の中空部の内面の直径と概ね同じとなる。また、芯棒２０はその外周の直径が長手方向には一定であることが好ましい。これにより採取用具１０の採取部１０ａにおける中空部の内面の直径も一定となる。 As can be seen from FIG. 2A, in this embodiment, the cylindrical body 11 is an isosceles trapezoidal sheet. There is no restriction | limiting in particular as a material of the cylindrical body 11, For example, in addition to Japanese paper, a pulp paper, etc., the fiber using non-laying cloth and the cloth hardened with paste can also be used together.
The core rod 20 is arranged in parallel with the lower base which is the trapezoid of the cylindrical body 11 as shown in FIG. 2 (b) with respect to the cylindrical body 11 in the unfolded state before being wound. To do. The diameter of the outer periphery of the core rod 20 is substantially the same as the diameter of the inner surface of the hollow part of the sampling tool 10 to be completed. Moreover, it is preferable that the outer diameter of the core rod 20 is constant in the longitudinal direction. Thereby, the diameter of the inner surface of the hollow part in the collection part 10a of the collection tool 10 is also constant.

そして図２（ｂ）に矢印ＩＩｂで示したように芯棒２０の外周面に、巻かれる前の展開された筒状体１１の下底を巻き付け、そのまま芯棒２０を軸線に沿って回転させながら上底に向けて転がす。これにより図３（ａ）に示したように、筒状体１１が芯棒２０の外周に巻かれた状態となる。その後、芯棒２０を抜き取ることで図３（ｂ）に示したように巻かれた状態の筒状体１１のみとなり、内側に中空部が形成される。このように巻かれていることで、筒状の壁部では薄い壁が複数重なった部位が形成される。そして、図３（ｃ）に示したように巻かれた状態の一方側の端部を樹脂１２等により固めることで保持部１０ｂを形成して巻かれた状態が保持される。これは例えば溶融した樹脂１２に、巻かれた状態の筒状体の一端側を浸した後に引き上げることで樹脂１２が固まることで行うことができる。当該樹脂としては熱可塑性樹脂を用いることができる。より具体的にな例としては、ポリビニルアルコール、ポリ酢酸ビニル、ポリビニルピロリドン、ブチラール樹脂、デンプン等が挙げられる。
これにより歯肉溝滲出液の採取用具１０となる。 Then, as shown by the arrow IIb in FIG. 2 (b), the lower bottom of the expanded cylindrical body 11 before being wound is wound around the outer peripheral surface of the core rod 20, and the core rod 20 is rotated as it is along the axis. While rolling towards the bottom. Thereby, as shown in FIG. 3A, the cylindrical body 11 is wound around the outer periphery of the core rod 20. Thereafter, by pulling out the core rod 20, only the cylindrical body 11 is wound as shown in FIG. 3B, and a hollow portion is formed inside. By being wound in this way, a portion where a plurality of thin walls overlap is formed in the cylindrical wall portion. And the holding | maintenance part 10b is formed and the state which was wound is hold | maintained by hardening the edge part of the one side of the wound state as shown in FIG.3 (c) with the resin 12 grade | etc.,. This can be performed by, for example, hardening the resin 12 by immersing one end side of the wound cylindrical body in the molten resin 12 and pulling it up. A thermoplastic resin can be used as the resin. More specific examples include polyvinyl alcohol, polyvinyl acetate, polyvinyl pyrrolidone, butyral resin, starch and the like.
Thereby, it becomes the extraction tool 10 of gingival crevicular fluid.

このように歯肉溝滲出液の採取用具１０は容易に製造することが可能であり、製造の観点からも利点がある。   In this manner, the gingival crevicular fluid collection tool 10 can be easily manufactured, and is advantageous from the viewpoint of manufacturing.

本形態では巻かれる前の展開された筒状体１１の形態として等脚台形であるシート状を用いた。しかしながらこれに限られず、他の形態が用いられてもよく、等脚でない台形、平行四辺形（正方形、長方形を含む）、三角形、円形、楕円形等が挙げられる。   In this embodiment, a sheet shape that is an isosceles trapezoid is used as the expanded cylindrical body 11 before being rolled. However, the present invention is not limited to this, and other forms may be used. Examples include trapezoids that are not equilateral, parallelograms (including squares and rectangles), triangles, circles, and ellipses.

以上説明した歯肉溝滲出液の採取用具１０は、例えば図４に示したように歯牙３０と歯肉３１との間に形成されている歯肉溝３２に採取部１０ａを挿入して、毛細管現象により滲出液３３を吸い上げて採取することができる。   In the gingival crevicular fluid collecting tool 10 described above, for example, as shown in FIG. 4, the sampling part 10a is inserted into the gingival sulcus 32 formed between the tooth 30 and the gingiva 31 to exude by capillary action. The liquid 33 can be sucked up and collected.
