Description

本発明は、鍼治療に用いる鍼灸針に関し、詳しくは、針体を皮膚に刺入するときに、所望の量の薬剤を体内に経皮的投与することができる鍼灸針に関するものである。   The present invention relates to an acupuncture needle used for acupuncture treatment, and more particularly to an acupuncture needle capable of transdermally administering a desired amount of a drug into the body when the needle body is inserted into the skin.

従来から、鍼治療に用いる鍼灸針として、通常の鍼治療の効能効果に加えて、薬剤を体内に経皮的投与し得るものがあった。このような鍼灸針の一例として、針体の表面に、その軸線と略平行の溝部を設けておき、この溝部に薬剤を保持したものが知られている。このような鍼灸針の針体を、治療部位(つぼ)に刺入することによって、通常の鍼治療の効能効果が得られると共に、体内に薬剤が経皮的投与されるようになっていた。(特許文献1参照)。
特開2003−116962号公報
Conventionally, there are acupuncture needles used for acupuncture treatment, in addition to the efficacy and effect of normal acupuncture treatment, a drug can be transdermally administered into the body. As an example of such an acupuncture needle, there is known one in which a groove portion substantially parallel to its axis is provided on the surface of a needle body and a drug is held in this groove portion. By inserting the needle body of such an acupuncture needle into a treatment site (acupuncture point), an effect effect of a normal acupuncture treatment is obtained, and a drug is transdermally administered into the body. (See Patent Document 1).
JP 2003-116962 A

しかしながら、上記特許文献1に記載の鍼灸針においては、鍼治療の際に、針体の表面が皮膚に擦られて刺入されるので、針体の溝部をかなり深く形成しなければ、薬剤を保持しておくことができないことがあった。そして、鍼治療の際に、針体の溝部に保持された薬剤がずれてしまうと、必要な量の薬剤が体内に投与されないこととなり、改善の余地があった。   However, in the acupuncture needle described in Patent Document 1, since the surface of the needle body is rubbed into the skin during acupuncture treatment, the drug must be formed unless the groove of the needle body is formed very deeply. In some cases, it could not be retained. When the drug held in the groove of the needle body is displaced during acupuncture, a necessary amount of drug is not administered into the body, and there is room for improvement.

そこで、本発明は、通常の鍼治療の効能効果に加えて、所望の量の薬剤を体内に経皮的投与することのできる鍼灸針を提供することを目的とする。   Accordingly, an object of the present invention is to provide an acupuncture needle capable of transdermally administering a desired amount of a drug into the body in addition to the efficacy effect of ordinary acupuncture treatment.

本発明に係る鍼灸針は、その中実の針体の所定位置に、該針体の軸に対して交差する方向に、針体の外周面の一位置から針体の軸中心を通って針体の外周面の他位置へ一直線に貫通する薬剤保持用の細孔を形成したものである。 The needle according to the present invention has a needle passing through the center of the needle body from one position on the outer peripheral surface of the needle body in a direction intersecting the axis of the needle body at a predetermined position of the solid needle body. The drug-holding pores are formed so as to penetrate straight to other positions on the outer peripheral surface of the body .

本発明によれば、薬剤を保持した針体を皮膚に刺入することで、通常の鍼治療の効能効果に加えて、薬剤を体内に経皮的投与することができる。この薬剤は、針体の細孔の内部に保持されているので、針体の表面が皮膚に擦られて刺入されても、薬剤がずれることがなく、所望の量の薬剤を体内に経皮的投与することができる。   According to the present invention, by inserting a needle body holding a drug into the skin, the drug can be transdermally administered into the body in addition to the effect of normal acupuncture. Since this drug is held inside the pores of the needle body, even if the surface of the needle body is rubbed against the skin and inserted, the drug does not shift and a desired amount of drug passes through the body. It can be administered dermally.

以下に図面を参照して、本発明の実施の形態について説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図1は、本発明による鍼灸針の一例としての円皮針を示す説明図であって、(a)は平面図を示し、(b)は正面図を示す。また、図2は、図1(b)に示す点線の範囲の拡大図である。   FIG. 1 is an explanatory view showing a circular needle as an example of an acupuncture needle according to the present invention, where (a) shows a plan view and (b) shows a front view. FIG. 2 is an enlarged view of the range of the dotted line shown in FIG.

図1に示すように、円皮針1は、粘着テープ2と、剥離紙3と、針体4と、樹脂材5とから構成されている。この粘着テープ2は、例えば、直径が15mm程度の円形状のもので、布、不織布、あるいはプラスチックテープなどでできており、その下面は粘着性を有し、皮膚に貼り付け可能とされている。この粘着テープ2の中央部には、図2に示すように、針体4を通す穴2aが空けられている。   As shown in FIG. 1, the circular needle 1 includes an adhesive tape 2, a release paper 3, a needle body 4, and a resin material 5. The adhesive tape 2 is, for example, a circular shape having a diameter of about 15 mm, and is made of cloth, non-woven fabric, plastic tape, or the like, and its lower surface has adhesiveness and can be attached to the skin. . As shown in FIG. 2, a hole 2 a through which the needle body 4 passes is formed in the central portion of the adhesive tape 2.

この粘着テープ2の下面の粘着面には、円形状の剥離紙3が貼付されている。この剥離紙3は、粘着テープ2の粘着面を保護するもので、図1に示すように、粘着テープ2よりも、やや大きめに形成されている。この剥離紙3の中央部には、図2に示すように、粘着テープ2の穴2aと同様の穴3aが空けられている。この剥離紙3は、図1(a)に示すように、所定の位置に切り込み3bが形成されており、穴3aを有する大きな片3cと、穴3aを有さない小片3dとに2分割できるようになっている。   A circular release paper 3 is affixed to the adhesive surface of the lower surface of the adhesive tape 2. The release paper 3 protects the adhesive surface of the adhesive tape 2 and is formed slightly larger than the adhesive tape 2 as shown in FIG. As shown in FIG. 2, a hole 3 a similar to the hole 2 a of the adhesive tape 2 is opened at the center of the release paper 3. As shown in FIG. 1 (a), the release paper 3 is provided with a cut 3b at a predetermined position, and can be divided into a large piece 3c having a hole 3a and a small piece 3d having no hole 3a. It is like that.

また、図1(b)に示すように、粘着テープ2の上面の非粘着面には樹脂材5が設けられ、この樹脂材5によって針体4が固定されている。この針体4は、線径が例えば0.1〜0.5mm程度のステンレスでできており、図2に示すように、例えばL字型に屈曲され、その先端部4aが粘着テープ2の穴2a及び剥離紙3の穴3aを通って、剥離紙3の下面側から突出している。なお、本実施例において、針体4の先端部4aの突出する長さは、例えば0.3mm程度(又はそれ以上)とされているが、その長さは任意に設定できる。   Further, as shown in FIG. 1B, a resin material 5 is provided on the non-adhesive surface of the upper surface of the adhesive tape 2, and the needle body 4 is fixed by the resin material 5. The needle body 4 is made of stainless steel having a wire diameter of about 0.1 to 0.5 mm, for example, and is bent into an L shape, for example, as shown in FIG. It protrudes from the lower surface side of the release paper 3 through 2a and the hole 3a of the release paper 3. In the present embodiment, the protruding length of the tip 4a of the needle body 4 is, for example, about 0.3 mm (or more), but the length can be arbitrarily set.

このような針体4の基端側4bを固定する樹脂材5は、射出成形樹脂、熱硬化樹脂、常温硬化樹脂、紫外線硬化樹脂又はエラストマー樹脂などでできており、針体4の基端側4bを覆うように射出成形される。これにより、針体4が粘着テープ2に固定される。   The resin material 5 for fixing the proximal end side 4b of the needle body 4 is made of an injection molding resin, a thermosetting resin, a room temperature curing resin, an ultraviolet curable resin, an elastomer resin, or the like. Injection molding is performed so as to cover 4b. Thereby, the needle body 4 is fixed to the adhesive tape 2.

また、針体4を粘着テープ2に固定する方法は、前記射出成形樹脂等の樹脂材5を針体4の基端部4bを覆うように射出成形するものに限られず、他の固定方法でもよい。例えば、樹脂材5としてエポキシ樹脂等の接着剤を用いて、針体4の基端部4bを粘着テープ2に接着固定してもよい。   Further, the method for fixing the needle body 4 to the adhesive tape 2 is not limited to the one in which the resin material 5 such as the injection molding resin is injection-molded so as to cover the base end portion 4b of the needle body 4, and other fixing methods may be used. Good. For example, the base end portion 4 b of the needle body 4 may be bonded and fixed to the adhesive tape 2 using an adhesive such as an epoxy resin as the resin material 5.

このような射出成形樹脂等又はエポキシ樹脂などの樹脂材5を用いて、針体4を粘着テープ2に固定する場合には、射出成形又は接着固定等に伴う樹脂材5のバリを防止するために、その中央下部に窪み5aが設けられている。   When the needle body 4 is fixed to the adhesive tape 2 using such an injection molding resin or the like or a resin material 5 such as an epoxy resin, in order to prevent burrs of the resin material 5 due to injection molding or adhesive fixing. In addition, a depression 5a is provided at the center lower portion.

なお、針体4の形状は、図2に示すL字型のものに限られず、樹脂材5を用いて粘着テープ2に固定できるものであれば、どのような形状でもよい。   The shape of the needle body 4 is not limited to the L shape shown in FIG. 2 and may be any shape as long as it can be fixed to the adhesive tape 2 using the resin material 5.

ここで、本発明による円皮針1においては、図2に示すように、針体4の所定位置に、具体的には、針体4の先端部4aの近傍にて体内に挿入される部分に、細孔6が形成されている。この細孔6は、針体4の軸に対して交差する方向、例えば図3に示すように、針体4の軸に対して垂直方向に貫通して形成されている。この細孔6の内部には、例えば痛み止めや局所麻酔剤などの薬剤7が保持されている。なお、この細孔6は、任意の形状、大きさに形成することができるが、本実施例においては、例えば円形形状の開口部で、その直径は数十μm程度とされている。   Here, in the circular skin needle 1 according to the present invention, as shown in FIG. 2, a portion to be inserted into the body at a predetermined position of the needle body 4, specifically, in the vicinity of the distal end portion 4 a of the needle body 4. In addition, pores 6 are formed. The pore 6 is formed so as to penetrate in a direction intersecting the axis of the needle body 4, for example, in a direction perpendicular to the axis of the needle body 4 as shown in FIG. 3. Inside the pores 6, for example, a medicine 7 such as a painkiller and a local anesthetic is held. The pores 6 can be formed in any shape and size, but in the present embodiment, for example, a circular opening has a diameter of about several tens of μm.

この細孔6の内部に薬剤7を保持するときは、針体4を医薬品の溶液に浸けてから、その表面に付着した溶液を拭き取って、細孔6の内側にのみ溶液を保持させる。そして、これを凍結乾燥させることで、細孔6の内部に薬剤7が保持された円皮針1を製造することができる。なお、細孔6に保持される薬剤7は、液体を凍結乾燥したものに限られず、粉末状のものでもよいし、膏薬でもよい。   When the drug 7 is held inside the pore 6, the needle body 4 is dipped in a pharmaceutical solution, and then the solution adhering to the surface is wiped off so that the solution is held only inside the pore 6. And the circular needle 1 by which the chemical | medical agent 7 was hold | maintained inside the pore 6 can be manufactured by freeze-drying this. In addition, the chemical | medical agent 7 hold | maintained at the pore 6 is not restricted to what freeze-dried the liquid, A powder form may be sufficient and a plaster may be sufficient.

このように構成された円皮針1を用いて鍼治療を行う際には、図4に示すように、剥離紙3の小さな片3dと粘着テープ2とを摘まんで持って、剥離紙3の大きな片3cを粘着テープ2から剥がす。この状態で、円皮針1の針体4を治療部位(つぼ)の位置に合わせて刺入しながら、粘着テープ2の粘着面が露出した部分を皮膚に貼り付けて固定する。さらに、粘着テープ2に残された剥離紙3の小片3dを剥がし、この部分の粘着面も皮膚に貼り付ける。これにより、手で押さえておかなくても、長時間、針体4を体内に刺入した状態とすることができる。   When performing acupuncture using the thus configured circular skin needle 1, as shown in FIG. 4, a small piece 3 d of the release paper 3 and the adhesive tape 2 are held and held. The large piece 3 c is peeled off from the adhesive tape 2. In this state, the needle body 4 of the circular skin needle 1 is inserted in accordance with the position of the treatment site (acupuncture point), and the portion where the adhesive surface of the adhesive tape 2 is exposed is affixed to the skin and fixed. Further, the small piece 3d of the release paper 3 left on the adhesive tape 2 is peeled off, and the adhesive surface of this part is also attached to the skin. Thereby, even if it does not hold down by hand, it can be in the state which inserted the needle body 4 in the body for a long time.

このようにして、円皮針1の針体4を所定の治療部位に刺入することにより、通常の鍼治療の効能効果に加えて、薬剤7を体内に経皮的投与することができる。このとき、薬剤7は、針体4に形成された細孔6の内部に保持されているので、針体4の表面が皮膚に擦られて刺入されても、薬剤7がずれることはない。したがって、鍼治療の際に、針体4の細孔6の内部に保持された薬剤7を漏れなく体内に投与することができ、必要とされた薬剤7の全量が経皮的投与されることになる。   In this way, by inserting the needle body 4 of the circular skin needle 1 into a predetermined treatment site, the drug 7 can be transdermally administered into the body in addition to the efficacy effect of normal acupuncture treatment. At this time, since the medicine 7 is held inside the pores 6 formed in the needle body 4, even if the surface of the needle body 4 is rubbed against the skin and inserted, the medicine 7 does not shift. . Therefore, during acupuncture, the drug 7 held inside the pore 6 of the needle body 4 can be administered into the body without omission, and the required amount of the drug 7 is transdermally administered. become.

以下に、他の実施形態について説明する。   Other embodiments will be described below.

図5は、本発明の第2の実施形態に係る円皮針1の針体4を示している。本実施形態においては、針体4の軸に対して斜め方向に、細孔6′が形成されている。この場合は、細孔6が針体4の軸に対して垂直方向に形成されたもの(図3参照)と比べて、その開口部を大きくできるので、鍼治療の際に、細孔6′の内部に保持された薬剤7が、短時間で体内に投与されることになる。   FIG. 5 shows the needle body 4 of the circular skin needle 1 according to the second embodiment of the present invention. In the present embodiment, a pore 6 ′ is formed in an oblique direction with respect to the axis of the needle body 4. In this case, since the opening can be made larger compared to the case where the pore 6 is formed in the direction perpendicular to the axis of the needle body 4 (see FIG. 3), the pore 6 ' The medicine 7 held inside the body is administered into the body in a short time.

図6は、本発明の第3の実施形態に係る円皮針1の針体4を示している。本実施形態においては、針体4の長手方向に、例えば2個の細孔6,6が並べて形成されている。この場合は、一本の針体4が保持できる薬剤7の量を2倍に増やすことができるので、鍼治療の際に、より多くの薬剤7を体内に投与することができる。なお、細孔6の個数に制限はなく、3個以上としてもよい。   FIG. 6 shows the needle body 4 of the circular skin needle 1 according to the third embodiment of the present invention. In the present embodiment, for example, two pores 6 and 6 are formed side by side in the longitudinal direction of the needle body 4. In this case, since the amount of the drug 7 that can be held by one needle body 4 can be doubled, more drug 7 can be administered into the body during acupuncture. The number of pores 6 is not limited and may be 3 or more.

また、図6に示すように、針体4に複数個の細孔6,6を形成した場合には、各細孔6に異なる種類の薬剤7を保持しておくことができる、という効果も得られる。   In addition, as shown in FIG. 6, when a plurality of pores 6, 6 are formed in the needle body 4, there is an effect that different types of medicines 7 can be held in each pore 6. can get.

なお、以上に説明した円皮針1は、例えばL字型に屈曲した針体4を、樹脂材5を用いて粘着テープ2に固定したものとしたが、本発明はこれに限られず、他の構成のものでもよい。例えば、図7に示すように、針体4の基端部4bを、針体4の軸に対して直交する面内で曲げて円形の部分を形成し、この円形とされた基端部4bを支持部として、粘着テープ2と支持用テープ8との間に固定した構成のものでもよい。図7中では省略したが、この粘着テープ2及び支持用テープ8の下面の粘着面に、図1に示すと同様の剥離紙3を貼付しておけば、鍼灸針1を皮膚に容易に貼り付けることができる。   In addition, although the circular needle 1 demonstrated above fixed the needle body 4 bent in L shape to the adhesive tape 2 using the resin material 5, for example, this invention is not limited to this, Other The thing of the structure of may be sufficient. For example, as shown in FIG. 7, the base end portion 4b of the needle body 4 is bent in a plane orthogonal to the axis of the needle body 4 to form a circular portion, and this base end portion 4b having a circular shape is formed. As a support portion, a configuration in which the support portion is fixed between the adhesive tape 2 and the support tape 8 may be used. Although omitted in FIG. 7, if the release paper 3 similar to that shown in FIG. 1 is attached to the adhesive surface of the adhesive tape 2 and the supporting tape 8, the acupuncture needle 1 can be easily applied to the skin. Can be attached.

また、本発明は、円皮針に適用したものに限られず、他の形状の鍼灸針に適用したものでもよい。例えば、図8に示すように、長さ数十mmの針体9の基端部に、例えばプレスチック製の針柄10が取り付けられた鍼灸針に適用することもできる。この場合においても、上述したものと同様の効果が得られる。   In addition, the present invention is not limited to the one applied to the circular needle, and may be applied to other shape needles. For example, as shown in FIG. 8, the present invention can be applied to an acupuncture needle in which a needle handle 10 made of, for example, a plastic is attached to a proximal end portion of a needle body 9 having a length of several tens of millimeters. Even in this case, the same effect as described above can be obtained.

このような鍼灸針において、針体9の長手方向に、薬剤保持用の細孔6を複数個並べて形成しておけば、鍼治療の際に、針体9を体内に刺入する深さに応じて、体内に投与される薬剤の量を適宜変えることができる。   In such an acupuncture needle, if a plurality of drug-holding pores 6 are formed side by side in the longitudinal direction of the needle body 9, the needle body 9 can be inserted into the body at the time of acupuncture treatment. Accordingly, the amount of drug administered into the body can be appropriately changed.
