Description

本発明は、鍼灸に用いられる円皮針に関する。   The present invention relates to a circular skin needle used for scissors.

円皮針（パイオネックス）は、針体と絆創膏とからなり、身体に貼る鍼である。
特許文献１には、円皮針において、一方の面が粘着面をなす絆創膏と、この絆創膏の粘着面側に剥離可能に貼り付けられる剥離紙と、基端側が絆創膏の他方の面側に固定され、先端側が絆創膏及び剥離紙の貫通孔（中央孔）から突出する針体と、を含んで構成されることが記載されている。なお、剥離紙は、切り込み線により貫通孔を有する側（大きい側の剥離紙）と有しない側（小さい側の剥離紙）とに２分割されることが記載されている。
特開２０００−５１３１５号公報 A circular needle (Pionex) consists of a needle and an adhesive bandage, and is a sticker to be attached to the body.
In Patent Document 1, in a circular needle, an adhesive bandage in which one surface forms an adhesive surface, a release paper that is detachably attached to the adhesive surface side of the adhesive bandage, and a proximal end side fixed to the other surface side of the adhesive bandage In addition, it is described that the tip side includes a bandage and a needle body protruding from a through hole (center hole) of the release paper. In addition, it is described that the release paper is divided into two by a cut line, that is, a side having a through hole (large release paper) and a side having no through hole (small release paper).
JP 2000-51315 A

しかしながら、特許文献１に記載の円皮針において、貫通孔を有する側（大きい側）の剥離紙を収容容器に固着させて用いるとき、針体が長い場合において貫通孔を有しない側（小さい側）の剥離紙とこの部分に粘着された絆創膏とを指で把持して一緒に捲り上げることで、貫通孔を有する側（大きい側）の剥離紙（収納容器）から円皮針を分離する際、針体の先端が貫通孔を有する側（大きい側）の剥離紙の貫通孔に接触してしまい、針体の先端への異物の付着や針体を損傷する原因となっていた。 However, in the circular needle described in Patent Document 1, when the release paper on the side having the through hole (large side) is fixed to the storage container and used, the side without the through hole when the needle body is long (small side) ) When separating the circular needle from the release paper (storage container) on the side with the through hole (large side) The tip of the needle body comes into contact with the through-hole of the release paper on the side having the through-hole (large side), which causes adhesion of foreign matter to the tip of the needle body and damage to the needle body.

ここで、絆創膏及び剥離紙の貫通孔の径が小さいほど絆創膏と針体とを固定する強度が強くなるが、針体が長い場合には貫通孔の直径を拡大しなければならないため、絆創膏と針体とを固定する強度が低下してしまうという問題があった。
本発明は、このような問題に着目してなされたもので、絆創膏と針体とを固定する強度を確保しつつ針体を保護することを目的とする。 Here, the smaller the through-hole diameter of the adhesive bandage and release paper, the stronger the strength to fix the adhesive bandage and the needle body, but when the needle body is long, the diameter of the through-hole must be enlarged, There was a problem that the strength for fixing the needle body was lowered.
The present invention has been made paying attention to such a problem, and an object thereof is to protect the needle body while securing the strength for fixing the adhesive bandage and the needle body.

そのため本発明では、剥離紙の切り込み線は、その中間部を大きい側の剥離紙側に凸とし、切り込み線の中央部にて貫通孔を横断する直線状の貫通孔切り込み部と、切り込み線の両端部にて貫通孔からオフセットした位置で直線状をなし貫通孔切り込み部に対して平行な直線切り込み部とを有する。また、前記凸部は、直線切り込み部の延長線を下底とし、貫通孔切り込み部を上底とし、下底の両端の内角が鋭角をなす台形形状とした。 For this reason, in the present invention, the cut line of the release paper is formed such that the middle portion thereof is convex to the release paper side of the larger side, and the straight through hole cut portion that crosses the through hole at the center portion of the cut line, It has a straight line shape at a position offset from the through hole at both ends, and has a straight cut part parallel to the through hole cut part. Further, the convex portion has a trapezoidal shape in which an extension line of the straight cut portion is a lower base, a through hole cut portion is an upper base, and inner angles at both ends of the lower base are acute angles.

本発明によれば、切り込み線の中間部により、剥離紙の貫通孔が２つの剥離紙に含まれて分割されるため、小さい側の剥離紙とこの部分に粘着された絆創膏とを指で把持して一緒に捲り上げることで、円皮針を大きい側の剥離紙（収納容器）から分離する際、針体の先端の軌跡上には貫通孔がなくなり、貫通孔を通過させる動作がなくなるため、針体が剥離紙に接触することによる異物の付着及び損傷を防止することができるという効果がある。   According to the present invention, since the through-hole of the release paper is included in the two release papers and divided by the middle part of the score line, the small release paper and the adhesive bandage adhered to this part are gripped with fingers. When the circular needle is separated from the release paper (storage container) on the larger side, the through hole disappears on the locus of the tip of the needle body, and the operation of passing the through hole is lost. There is an effect that it is possible to prevent adhesion and damage of foreign matters due to the contact of the needle body with the release paper.

ここで、本発明の円皮針１について図１〜図３を用いて詳細に説明する。
図１は、本発明の円皮針１の断面図である。図２は、図１のＡ−Ａ線における平面図である。図３は、円皮針１の剥離紙３の貫通孔６を含むように剥離紙３を第１剥離紙８及び第２剥離紙９の２つに分割して第２剥離紙９とこの部分に粘着する絆創膏２とを指で把持して捲り上げることにより円皮針１を第１剥離紙８（支持体としての収納容器１１）から分離する状態を示す断面図である。 Here, the circular needle 1 of the present invention will be described in detail with reference to FIGS.
FIG. 1 is a cross-sectional view of a circular needle 1 of the present invention. FIG. 2 is a plan view taken along line AA of FIG. FIG. 3 shows that the release paper 3 is divided into two parts, that is, a first release paper 8 and a second release paper 9 so as to include the through-hole 6 of the release paper 3 of the circular needle 1. It is sectional drawing which shows the state which isolate | separates the circular needle 1 from the 1st release paper 8 (storage container 11 as a support body) by grasping the bandage 2 which adheres to a finger | toe with a finger, and rolling up.

円皮針１は、大別して、絆創膏２と、剥離紙３と、針体４とを含んで構成され、収納容器１１に収納される。
絆創膏２は、円形であり、中央部に貫通孔５を有し、上面２ａには針体４の基端側が固定されている一方、下面２ｂには粘着面が形成されている。
剥離紙３は、絆創膏２より直径が大きい円形であり、中央部に貫通孔６を有し、上面３ａが絆創膏２の粘着面２ｂ側に剥離可能に貼り付けられる。 The circular needle 1 is roughly divided and includes a bandage 2, a release paper 3, and a needle body 4, and is stored in a storage container 11.
The adhesive bandage 2 is circular, has a through hole 5 in the center, and the proximal end side of the needle body 4 is fixed to the upper surface 2a, while an adhesive surface is formed on the lower surface 2b.
The release paper 3 has a circular shape with a diameter larger than that of the adhesive bandage 2, has a through-hole 6 in the center, and an upper surface 3 a is detachably attached to the adhesive surface 2 b side of the adhesive bandage 2.

この剥離紙３には、図２に示すように、剥離紙３の貫通孔６を横断する切り込み線７が形成されている。
切り込み線７は、平面視（図２）において、切り込み線７の中間部で貫通孔６を横断し、両端部が貫通孔６からオフセットした位置で直線状をなし、両端部に対し中間部が凸をなしている。この切り込み線７により、剥離紙３は、第１剥離紙８と第２剥離紙９との大小２つに分割される。 As shown in FIG. 2, a cut line 7 is formed in the release paper 3 so as to cross the through hole 6 of the release paper 3.
The cut line 7 crosses the through hole 6 at the middle part of the cut line 7 in a plan view (FIG. 2) and forms a straight line at positions where both end parts are offset from the through hole 6, and the middle part is at both ends. Convex. With this score line 7, the release paper 3 is divided into two parts, a first release paper 8 and a second release paper 9.

なお、第１剥離紙８及び第２剥離紙９には、貫通孔６が半分ずつ形成されている。更に、第１剥離紙８の下面は、後述する収納容器１１の剥離紙配置部１６の上面１６ａに熱溶着されている。
剥離紙３の切り込み線７は、その中間部で、貫通孔６から、円形の樹脂材１０の外径と同じ位置まで上下方向にそれぞれ切り込まれる貫通孔切り込み部７ａを含んでいる。この貫通孔切り込み部７ａにより、第２剥離紙９の貫通孔６側の先端部には第１直線部９ａが形成される。 The first release paper 8 and the second release paper 9 have half through-holes 6 formed therein. Furthermore, the lower surface of the first release paper 8 is thermally welded to the upper surface 16a of the release paper placement portion 16 of the storage container 11 described later.
The cut line 7 of the release paper 3 includes a through hole cut portion 7 a that is cut in the vertical direction from the through hole 6 to the same position as the outer diameter of the circular resin material 10. By the through-hole cut portion 7a, a first straight portion 9a is formed at the tip of the second release paper 9 on the through-hole 6 side.

そして、切り込み線７は、その両端部が貫通孔６からオフセットした位置に直線状に切り込まれる直線切り込み部７ｅを含んで形成している。直線切り込み部７ｅは、貫通孔切り込み部７ａと平行に形成されている。この直線切り込み部７ｅにより、第２剥離紙９には第２直線部９ｅが形成される。この第２直線部９ｅ（直線切り込み部７ｅ）は、図２に示す通り、剥離紙３の第１剥離紙８及び第２剥離紙９の両側に形成された円形の切り欠き３ｃまで形成されている。   And the cut line 7 is formed including the straight cut part 7e cut in the shape of a straight line in the position where the both ends were offset from the through-hole 6. FIG. The straight cut portion 7e is formed in parallel with the through hole cut portion 7a. A second straight line portion 9e is formed on the second release paper 9 by the straight cut portion 7e. As shown in FIG. 2, the second straight line portion 9 e (straight cut portion 7 e) is formed up to the circular cutout 3 c formed on both sides of the first release paper 8 and the second release paper 9 of the release paper 3. Yes.

更に、切り込み線７は、貫通孔切り込み部７ａの外端７ｂ（第１直線部９ａの外端９ｂ）から直線切り込み部７ｅの内端７ｄ（第２直線部９ｅの内端９ｄ）まで、それぞれ径方向外側に円周方向所定角度で切り込まれる２つの斜め切り込み部７ｃを含んでいる。この斜め切り込み部７ｃにより、第２剥離紙９には傾斜部９ｃが形成される。
なお、傾斜部９ｃ（斜め切り込み部７ｃ）は、直接貫通孔６を含んで形成するようにしてもよい。 Further, the cut line 7 extends from the outer end 7b of the through hole cut portion 7a (the outer end 9b of the first straight portion 9a) to the inner end 7d of the straight cut portion 7e (the inner end 9d of the second straight portion 9e). Two oblique cut portions 7c cut at a predetermined angle in the circumferential direction are included on the radially outer side. An inclined portion 9c is formed on the second release paper 9 by the oblique cut portion 7c.
In addition, you may make it form the inclination part 9c (diagonal cut | notch part 7c) including the through-hole 6 directly.

このようにして、切り込み線７の凸部は、貫通孔切り込み部７ａ及び斜め切り込み部７ｃにより台形形状をなす。
なお、第２直線部９ｅ（直線切り込み部７ｅ）の形成される位置は、後述する容器本体１２の剥離紙配置部１６に形成された折り曲げ溝１８と一致している。
針体４は、ステンレス鋼等で構成されており、Ｌ字状に屈曲形成されている。その基端（上端）側は、絆創膏２の非粘着面側である上面２ａ側に樹脂材１０により覆われることで固定されている。 Thus, the convex part of the cut line 7 forms a trapezoidal shape by the through-hole cut part 7a and the oblique cut part 7c.
In addition, the position where the 2nd linear part 9e (straight cut part 7e) is formed corresponds with the bending groove | channel 18 formed in the peeling paper arrangement | positioning part 16 of the container main body 12 mentioned later.
The needle body 4 is made of stainless steel or the like, and is bent in an L shape. The base end (upper end) side is fixed by being covered with the resin material 10 on the upper surface 2 a side which is the non-adhesive surface side of the adhesive bandage 2.

一方、針体４の先端（下端）側は、絆創膏２及び剥離紙３に形成された貫通孔５，６から突出している。この突出した部分により、針体４を皮下に刺通可能となる。針体４の突出部の長さは適宜決められる。
円皮針１を収納する収納容器１１は、容器本体１２と、シールシート１３とから構成される。容器本体１２は、プラスチック等により形成され、鍔部１４と、筒部１５と、剥離紙配置部１６と、針体収納部１７とから構成される。 On the other hand, the tip (lower end) side of the needle body 4 protrudes from the through holes 5 and 6 formed in the adhesive bandage 2 and the release paper 3. This protruding portion allows the needle body 4 to be pierced subcutaneously. The length of the protruding portion of the needle body 4 is appropriately determined.
A storage container 11 for storing the circular needle 1 includes a container body 12 and a seal sheet 13. The container main body 12 is formed of plastic or the like, and includes a collar portion 14, a cylinder portion 15, a release paper placement portion 16, and a needle body storage portion 17.

剥離紙配置部１６は、剥離紙３より直径の大きい略円形板状であり、この略中央部には図４の下側に突出する円筒状の針体収納部１７が形成されている。そして、剥離紙配置部１６は、切り込み線７が形成されている第２剥離紙９側が大きく形成され、この部分が、円皮針１を取り出す際において第２剥離紙９とこの部分に粘着された絆創膏３とを一緒に把持するために指を入れる部分となる。   The release paper placement portion 16 has a substantially circular plate shape with a diameter larger than that of the release paper 3, and a cylindrical needle body storage portion 17 protruding downward in FIG. The release paper placement portion 16 is formed to be large on the second release paper 9 side where the cut line 7 is formed, and this portion is adhered to the second release paper 9 and this portion when the circular needle 1 is taken out. It becomes a part to put a finger to hold the adhesive bandage 3 together.

剥離紙配置部１６の上面１６ａは、第１剥離紙８の下面の外周近傍においてのみ第１剥離紙８と熱溶着されている。そして図１に示す通り、剥離紙配置部１６には、剥離紙３の第２直線部９ｅと同じ位置に下から上に向かうＶ字状の折り曲げ溝１８が形成されている。この折り曲げ部１８は、図２では、剥離紙配置部１６の裏側に剥離紙３の第２直線部９ｅと同じ位置に形成されている。   The upper surface 16 a of the release paper placement unit 16 is thermally welded to the first release paper 8 only in the vicinity of the outer periphery of the lower surface of the first release paper 8. As shown in FIG. 1, a V-shaped bent groove 18 is formed in the release paper placement portion 16 at the same position as the second linear portion 9 e of the release paper 3 from the bottom to the top. In FIG. 2, the bent portion 18 is formed at the same position as the second linear portion 9 e of the release paper 3 on the back side of the release paper placement portion 16.

剥離紙配置部１６の外端には、筒部１５が形成されている。この筒部１５の下面１５ｂは、針体収納部１７の下面と面一になるように形成されている。
筒部１５の上端には、径方向外側に広がるように鍔部１４が形成されている。この鍔部１４の上面１４ａには、シールシート１３が剥離可能に貼り付けられている。これにより円皮針１を収納容器１１内に密封して収納可能とする。 A cylindrical portion 15 is formed at the outer end of the release paper placement portion 16. The bottom surface 15 b of the cylindrical portion 15 is formed to be flush with the bottom surface of the needle body storage portion 17.
A flange portion 14 is formed at the upper end of the cylindrical portion 15 so as to spread outward in the radial direction. A seal sheet 13 is detachably attached to the upper surface 14a of the flange 14. Thereby, the circular needle 1 is sealed in the storage container 11 and can be stored.

次に、図３に示すように、円皮針１を第１剥離紙８（支持体としての収納容器１１）から分離する状態について説明する。
円皮針１を第１剥離紙８（収容容器１１）から分離するには、先ず、シールシート１３を容器本体１２から剥がす。そして、図１に示す剥離紙配置部１６の折り曲げ溝１８において容器本体１２の右側を時計周りに折り曲げる。更に、第２剥離紙９とこの部分に粘着する絆創膏２とを指で掴み、第１剥離紙８のＢ点を支点として第２剥離紙９を絆創膏２と共に反時計回りに捲り上げる。 Next, as shown in FIG. 3, a state in which the circular needle 1 is separated from the first release paper 8 (the storage container 11 as a support) will be described.
In order to separate the circular needle 1 from the first release paper 8 (storage container 11), first, the seal sheet 13 is peeled off from the container body 12. And the right side of the container main body 12 is bent clockwise in the bending groove 18 of the release paper arrangement | positioning part 16 shown in FIG. Further, the second release paper 9 and the adhesive bandage 2 that adheres to this portion are grasped with a finger, and the second release paper 9 is rolled up together with the adhesive bandage 2 counterclockwise with the point B of the first release paper 8 as a fulcrum.

ここで剥離紙３には、切り込み線７により剥離紙３の貫通孔５が第１剥離紙８及び第２剥離紙９にそれぞれ含まれて分割されるため、針体４の先端の軌跡上には貫通孔６（第２剥離紙９）がなくなる。
すなわち、切り込み線７の凸部（貫通孔切り込み部７ａ及び斜め切り込み部７ｃ）は、台形形状をなしているため、これに対応する形状を有する第２剥離紙９（第１直線部９ａ及び傾斜部９ｃ）の先端部が針体４を保持した状態のまま、円皮針１を第１剥離紙８（収納容器１１）から分離可能となる。これにより、貫通孔６を通過させる動作がなくなるため、針体４が剥離紙３に接触することによる異物の付着及び損傷を防止する。 Here, in the release paper 3, the through-hole 5 of the release paper 3 is included in the first release paper 8 and the second release paper 9 by the cut line 7, so that the release paper 3 is divided on the locus of the tip of the needle body 4. Eliminates the through-hole 6 (second release paper 9).
That is, since the convex portions (through-hole cut portions 7a and oblique cut portions 7c) of the cut line 7 have a trapezoidal shape, the second release paper 9 (the first straight portion 9a and the inclined portion) having a shape corresponding thereto. The circular needle 1 can be separated from the first release paper 8 (storage container 11) while the tip of the portion 9c) holds the needle body 4. Thereby, since the operation | movement which lets the through-hole 6 pass is lost, the adhesion and damage of the foreign material by the needle body 4 contacting the release paper 3 are prevented.

そして、円皮針１を収納容器１１から取り外した後に円皮針１の針体４を皮下に刺通させる際には、第２剥離紙９の先端部である第１直線部９ａを、刺通させる部位に針体４の位置を合わせると共に、第１剥離紙８側に貼り付けられていた絆創膏２の下面２ｂを皮膚に貼り付ける。
更に、第２剥離紙９の先端側を反時計回りに捲ることで、第２剥離紙９と粘着する部分である絆創膏２の下面２ｂを第２剥離紙９から剥離しつつ、この部分の絆創膏２を皮膚に貼り付ける。これにより、針体４を皮下に刺通した状態で円皮針１を皮膚に貼り付けることが可能となる。 Then, when the needle body 4 of the circular skin needle 1 is pierced subcutaneously after the circular skin needle 1 is removed from the storage container 11, the first straight portion 9 a that is the tip of the second release paper 9 is inserted into the needle. While aligning the position of the needle body 4 with the site | part to let through, the lower surface 2b of the adhesive plaster 2 currently affixed on the 1st release paper 8 side is affixed on skin.
Furthermore, by peeling the tip side of the second release paper 9 counterclockwise, the lower surface 2b of the adhesive bandage 2 which is a part that adheres to the second release paper 9 is peeled off from the second release paper 9, and this part of the adhesive bandage 2 is applied to the skin. As a result, the circular needle 1 can be attached to the skin with the needle body 4 pierced subcutaneously.

次に、本発明の円皮針１との比較のため、従来の円皮針２１（例えば特許文献１に記載の円皮針）について図４〜図６を用いて説明する。
図４は、従来の円皮針２１の断面図である。図５は、図４のＡ−Ａ線における平面図である。図６は、従来の円皮針２１を剥離紙２３（支持体としての収納容器１１）から分離させた場合における針体４の先端の軌道を示す断面図である。なお、図１〜図３にて説明した円皮針１と同じ部分については同じ符号を付し、詳細な説明は省略する。 Next, for comparison with the circular skin needle 1 of the present invention, a conventional circular skin needle 21 (for example, the circular skin needle described in Patent Document 1) will be described with reference to FIGS.
FIG. 4 is a cross-sectional view of a conventional circular needle 21. FIG. 5 is a plan view taken along line AA of FIG. FIG. 6 is a cross-sectional view showing the trajectory of the tip of the needle body 4 when the conventional circular needle 21 is separated from the release paper 23 (the storage container 11 as a support). In addition, the same code | symbol is attached | subjected about the same part as the circular needle 1 demonstrated in FIGS. 1-3, and detailed description is abbreviate | omitted.

従来の円皮針２１における剥離紙２３には、図５に示す通り、貫通孔５，６より右側に縦方向に直線の切り込み線２７が形成されている。この切り込み線２７により、剥離紙２３は、中央部の貫通孔６を含む第１剥離紙２８と、貫通孔６を含まない三日月状の第２剥離紙２９とに２分割される。
円皮針２１を剥離紙２３（収容容器１１）から分離する際には、第２剥離紙２９とこの部分に粘着する絆創膏２とを指で把持し、第１剥離紙２８のＢ点を支点として第２剥離紙２９を絆創膏２と共に反時計回りに捲り上げる。 As shown in FIG. 5, a linear cut line 27 is formed on the release paper 23 in the conventional circular needle 21 in the vertical direction on the right side of the through holes 5 and 6. With this cut line 27, the release paper 23 is divided into a first release paper 28 that includes the central through-hole 6 and a crescent-shaped second release paper 29 that does not include the through-hole 6.
When separating the circular needle 21 from the release paper 23 (container 11), the second release paper 29 and the adhesive bandage 2 that adheres to this portion are held with fingers, and the point B of the first release paper 28 is a fulcrum. The second release paper 29 is rolled up counterclockwise together with the adhesive plaster 2.

この際、円皮針２１の針体４が長い場合には、針体４の先端の軌道上に剥離紙２３（貫通孔６）があるため、針体４が第１剥離紙２８に接触してしまう。この結果、針体４を損傷することや針体４に異物が付着するおそれがあった。針体４が剥離紙２３に接触することを防止するためには、剥離紙２３の貫通孔６の直径を大きくすることが考えられる。
しかしながら、剥離紙２３の貫通孔６の直径を大きくすると、絆創膏２と針体４とを固定する強度が低下してしまう。 At this time, when the needle body 4 of the circular needle 21 is long, the release body 23 (through hole 6) is on the track of the tip of the needle body 4, so that the needle body 4 contacts the first release paper 28. End up. As a result, the needle body 4 may be damaged or foreign matter may adhere to the needle body 4. In order to prevent the needle body 4 from coming into contact with the release paper 23, it is conceivable to increase the diameter of the through hole 6 of the release paper 23.
However, when the diameter of the through hole 6 of the release paper 23 is increased, the strength for fixing the adhesive bandage 2 and the needle body 4 is reduced.

このため、本発明では、図１〜図３に示すように、円皮針１の剥離紙３を、貫通孔６を横断する切り込み線７を形成して第１剥離紙８及び第２剥離紙９の２つに分割することで、円皮針１の針体４が長い場合においても、円皮針４を捲り上げて剥離紙３から剥がす際に、針体４が剥離紙３に接触しないようにして、針体４を保護している。
なお、本発明の円皮針１では、絆創膏２及び剥離紙３の貫通孔５，６の径を従来の円皮針２１の貫通孔より小さくして、絆創膏２と針体４とを固定する強度を十分に確保するようにしてもよい。 For this reason, in this invention, as shown in FIGS. 1-3, the release paper 3 of the circular needle | hook 1 forms the cut line 7 which crosses the through-hole 6, and forms the 1st release paper 8 and the 2nd release paper 9, even when the needle body 4 of the circular needle 1 is long, the needle body 4 does not contact the release paper 3 when the circular needle 4 is lifted and peeled off from the release paper 3. In this way, the needle body 4 is protected.
In addition, in the circular needle 1 of this invention, the diameter of the through-holes 5 and 6 of the adhesive bandage 2 and the release paper 3 is made smaller than the through-hole of the conventional circular skin needle 21, and the adhesive bandage 2 and the needle body 4 are fixed. You may make it ensure sufficient intensity | strength.

本実施形態によれば、一方の面２ｂが粘着面をなす絆創膏２と、この絆創膏２の粘着面２ｂ側に剥離可能に貼り付けられて、切り込み線７により大小２つに分割され、大きい側（第１剥離紙８）が支持体（収納容器１１）に固着される剥離紙３と、基端側が絆創膏２の他方の面２ａ側に固定され、先端側が絆創膏２及び剥離紙３の貫通孔６から突出する針体４と、を含んで構成される円皮針１において、剥離紙３の切り込み線７の中間部（貫通孔切り込み部７ａ、斜め切り込み部７ｃ）を大きい側の剥離紙８側に凸として、切り込み線７の中間部を貫通孔６を横断させて形成した。このため、剥離紙３の貫通孔６が２つの剥離紙８，９に含まれて分割される一方、第２剥離紙９とこの部分に粘着された絆創膏２とを指で把持して捲り上げることで、円皮針１を第１剥離紙８（収納容器１１）から分離する際に、針体４の先端の軌跡上には貫通孔６（剥離紙３）がなくなり、貫通孔６を通過させる動作がなくなるため、針体４が剥離紙３に接触することによる異物の付着及び損傷を防止する。そして、貫通孔６の直径を小さくすることが可能であるため、絆創膏２と針体４とを固定する強度を十分に確保することができる。   According to the present embodiment, the adhesive bandage 2 in which one surface 2b forms an adhesive surface and the adhesive surface 2b side of the adhesive bandage 2 are detachably pasted and divided into two large and small by the cut line 7, and the larger side The release paper 3 (first release paper 8) is fixed to the support (storage container 11), the base end side is fixed to the other surface 2a side of the adhesive bandage 2, and the distal end side is a through-hole of the adhesive bandage 2 and the release paper 3 In the circular needle 1 configured to include the needle body 4 protruding from 6, the intermediate portion of the cut line 7 of the release paper 3 (through-hole cut portion 7a, oblique cut portion 7c) is the release paper 8 on the larger side. The intermediate portion of the cut line 7 is formed so as to cross the through-hole 6 so as to protrude to the side. For this reason, while the through-hole 6 of the release paper 3 is divided by being included in the two release papers 8 and 9, the second release paper 9 and the adhesive bandage 2 adhered to this part are grasped with a finger and rolled up. Thus, when the circular needle 1 is separated from the first release paper 8 (storage container 11), the through hole 6 (release paper 3) disappears on the locus of the tip of the needle body 4 and passes through the through hole 6. This eliminates the operation to prevent foreign matter from attaching and damaging when the needle body 4 contacts the release paper 3. And since it is possible to make the diameter of the through-hole 6 small, the intensity | strength which fixes the adhesive bandage 2 and the needle body 4 can fully be ensured.

また本実施形態によれば、凸部（貫通孔切り込み部７ａ及び斜め切り込み部７ｃ）は、台形形状をなす。このため、円皮針１の針体４を皮下に刺通する際に、針体４の位置を容易に合わせることができる。   Further, according to the present embodiment, the convex portions (the through-hole cut portions 7a and the oblique cut portions 7c) have a trapezoidal shape. For this reason, when the needle body 4 of the circular needle 1 is pierced subcutaneously, the position of the needle body 4 can be easily adjusted.
