Description

【0001】
【発明の属する技術分野】
本発明は、X線造影糸を有したガーゼに関する。
【0002】
【従来の技術】
従来、この種のガーゼは、例えば手術の際に使用され、施術後のX線撮影により除去されずに体内に残ってしまっていないか確認できるように、硫酸バリウムなどを含有したX線造影糸が織り込まれている。そして、このX線造影糸を有する構成としては、例えば図2に示すガーゼ10ように、経糸11の一部がX線造影糸12に置換されて木綿の経糸11および緯糸13がX線造影糸12とともに交互に交差して平織されている。
【0003】
【発明が解決しようとする課題】
ところで、ガーゼ10は、吸水性、通気性、被覆性など各種医療措置に対応すべく経糸11および緯糸13が交互に交差した平組織を有する平織構造が採られている。そして、X線造影糸12は、硫酸バリウムなどのX線造影のための材料を含有することから、木綿糸に比して屈曲しにくい。このため、X線造影糸12を有するガーゼ10を切断などによりある程度の小さい面積となると、ピンセットでつまむなどの外部からの応力が作用した際に、X線造影糸12がガーゼ10から抜け落ちるおそれがある問題がある。
【0004】
本発明は、上記問題点に鑑みなされたもので、X線造影糸の抜け落ちを防止したガーゼを提供することを目的とする。
【0005】
【課題を解決するための手段】
請求項1記載のガーゼは、木綿の経糸と緯糸とが交互に交差して平織りされ平組織を有したガーゼ本体に、X線造影糸が織り糸と互いにもじれながら前記経糸と前記緯糸とのいずれか一方と織り込まれ、前記X線造影糸が前記経糸と前記緯糸とのいずれか他方と略平行なもじり組織が形成され、前記織り糸が前記X線造影糸の表側から交互に前記ガーゼ本体の緯糸の裏面側に掛け渡されたものである。
【0006】
そして、木綿の経糸と緯糸とが交互に交差させて平織りし平組織を形成するガーゼ本体に、X線造影糸が織り糸と互いにもじれながら経糸と緯糸とのいずれか一方と織り込み、X線造影糸が経糸と緯糸とのいずれか他方と略平行となるもじり組織を形成することにより、織り糸がX線造影糸に絡み付く状態となり、X線造影糸の抜け落ちが防止される。
【0007】
請求項2記載のガーゼは、請求項1記載のガーゼにおいて、織り糸は、木綿糸であるものである。
【0008】
そして、織り糸として木綿糸を用いることにより、織り糸がガーゼ本体を構成する経糸および緯糸と同質となり、外観が向上するとともに、織り糸として経糸および緯糸を用いることが可能で、製造性が向上する。
【0009】
【発明の実施の形態】
以下、本発明のガーゼの一実施の形態を図面を参照して説明する。
【0010】
図1において、1はガーゼで、このガーゼ1は、木綿の経糸2および緯糸3が交互に交差して平織りされ平組織を有するガーゼ本体4を有している。そして、このガーゼ本体4には、X線造影糸5が経糸2と同質および同形状の木綿糸である織り糸6ともじれながら緯糸3にもじり織りにて織り込まれている。
【0011】
すなわち、平組織を有するガーゼ本体4の一面側である表面側で隣接する経糸2,2間にX線造影糸5が位置し、もじり織り用の織り糸6がX線造影糸5の表側から交互にガーゼ本体4の緯糸3の裏面側に掛け渡されて、ガーゼ1は経糸2,2と緯糸3,3とによる平組織と、X線造影糸5と織り糸6とによるもじり組織とを有している。
【0012】
そして、X線造影糸5は、例えばポリプロピレン、ポリ塩化ビニル、シリコンなどの繊維状樹脂に硫酸バリウムが含浸されて製糸されたものである。また、X線造影糸5は、その特性上、経糸2、緯糸3および織り糸6より太くかつ可撓性が低い。このため、織り込まれたX線造影糸5はほぼ直線状となり、ガーゼ1は直線状となるX線造影糸5がガーゼ本体4の経糸2と略平行に位置し織り糸6がX線造影糸5に絡み付く状態のもじり組織が形成されている。
【0013】
上述したように、平織構造のガーゼ本体4にX線造影糸5および織り糸6をもじり織りにて織り込みガーゼ1を形成するため、ガーゼ全体4の構造は平組織であり、ガーゼ1の特性を変更することなく、従来のX線造影糸5を平織りしたガーゼ10に比して引き抜き抵抗が極めて大きくなってX線造影糸5の抜け落ちを防止できる。
【0014】
このため、手術用として体内に使用するなどの医療措置に用いるガーゼ1に接着剤などの添加物を使用することなくX線造影糸5を抜け落ちずに固定して設けることができる。
【0015】
さらに、ガーゼ本体4ももじり織りすると、木綿糸である経糸2および緯糸3は細く剛性がないために糸が寄ってしまうおそれがあるが、ガーゼ本体4は従来の平組織でX線造影糸5の部分のみを選択的にもじり織りとするので、X線造影糸5が抜け落ちることなく、従来のガーゼ10の機能を維持できるとともに、織り方に影響を受けることなく交差状のままで形成できる。
【0016】
そして、X線造影糸5が抜け落ちないため、確実にX線撮影によりガーゼ1の有無を確認できる。
【0017】
また、もじり織りは平織りに並ぶ四原組織であり、一般的に普及した織り方で形成できることから、上述したように従来のガーゼ10と同様に工程が煩雑とならず容易に形成できる。
【0018】
さらに、X線造影糸5ともじる織り糸6を経糸2と同質および同形状の木綿糸を用いるため、ガーゼ本体4にX線造影糸5のみが織り込まれた状態となり、外観が向上するとともに、織り糸6として経糸2を用いることができ、別途種類のことなる織り糸6を用いる必要がなく、製造性を向上でき、異質の織り糸を用いる場合に比してガーゼ1としての機能を向上できる。
【0019】
なお、上記実施の形態において、X線造影糸5としては、X線造影性を有したいずれの材料にて形成してもよい。
【0020】
また、ガーゼ1を形成する際にX線造影糸5および織り糸6を織り込んだり、あらかじめ平織りして形成したガーゼ本体4にX線造影糸5および織り糸6をもじり織りにより編み込むようにして織り込むなどしてもよい。
【0021】
また、織り糸6としては、経糸2と同質および同形状に限らず、異なる糸を用いてもよい。
【0022】
そして、X線造影糸5を経糸2と略平行に位置させて織り糸6ともじりながら緯糸3ともじり織りしたが、緯糸3と略平行に位置させて経糸2ともじり織りしてもよい。
【0023】
【実施例】
次に、上記実施の形態のガーゼの実験例を説明する。
【0024】
ガーゼ本体4を構成する経糸2および緯糸3は、40番手である約453.59〔g〕×約768.10〔m〕×40のものを用いた。そして、ガーゼ1は、1cm2で縦12±1〔本〕、横12±1〔本〕の条数で、標準幅が30+5〔cm〕、30−1.0〔cm〕に平織りされたものである。そして、得られたガーゼ1を長さ300mm、幅50mmに裁断して試料片とした。なお、X線造影糸5は、長さ寸法が200mmである。また、X線造影糸5としては、ポリプロピレン樹脂39%、硫酸バリウム60%、その他の添加剤1%の組成のものを用いた。
【0025】
そして、図示しない測定装置のチャック間が200mmとなるように試料片を保持し、X線造影糸5を引っ張りスピード300mm/分で引っ張り、その引っ張り荷重を測定した。なお、比較試料として、X線造影糸5を平織りした従来のガーゼ10を用いた。その結果を表1に示す。
【0026】
【表1】

Figure 0003658308
この表1に示す結果から、平織構造のガーゼ本体4にX線造影糸5および織り糸6をもじり織りにて織り込んで形成した本実施例のガーゼ1は、従来のX線造影糸5を平織りしたガーゼ10に比して、X線造影糸5の引き抜き抵抗が約20倍強となり、X線造影糸5が極めて抜け落ちにくくなっていることがわかる。
【0027】
【発明の効果】
請求項1記載のガーゼによれば、木綿の経糸と緯糸とが交互に交差する平組織のガーゼ本体に、X線造影糸および織り糸をもじりなから織り込んでもじり組織を形成するため、織り糸がX線造影糸に絡み付く状態となり、X線造影糸の抜け落ちを防止できる。
【0028】
請求項2記載のガーゼによれば、請求項1記載のガーゼの効果に加え、織り糸として木綿糸を用いるため、織り糸がガーゼ本体を構成する経糸および緯糸と同質となり、外観を向上できるとともに、織り糸として経糸および緯糸を用いることができ、製造性を向上できる。

BACKGROUND OF THE INVENTION
The present invention relates to a gauze having an X-ray contrast yarn.
[0002]
[Prior art]
Conventionally, this type of gauze has been used in, for example, surgery, and an X-ray contrast yarn containing barium sulfate or the like so that it can be confirmed whether it remains in the body without being removed by radiography after the operation. Is interwoven. As a configuration having the X-ray contrast yarn, for example, as shown in FIG. 2, a part of the warp 11 is replaced with the X-ray contrast yarn 12 so that the cotton warp 11 and the weft 13 are the X-ray contrast yarn. 12 are alternately crossed and plain woven.
[0003]
[Problems to be solved by the invention]
By the way, the gauze 10 has a plain weave structure having a plain structure in which the warps 11 and the wefts 13 are alternately crossed in order to cope with various medical measures such as water absorption, breathability, and covering properties. Since the X-ray contrast yarn 12 contains a material for X-ray contrast such as barium sulfate, it is less likely to bend than cotton yarn. For this reason, when the gauze 10 having the X-ray contrast thread 12 has a certain small area by cutting or the like, the X-ray contrast thread 12 may fall out of the gauze 10 when an external stress such as pinching with tweezers is applied. There is a problem.
[0004]
The present invention has been made in view of the above problems, and an object of the present invention is to provide a gauze that prevents the X-ray contrast yarn from falling off.
[0005]
[Means for Solving the Problems]
The gauze according to claim 1 is a gauze main body having a plain structure in which cotton warps and wefts alternately cross each other, and the X-ray contrast yarns are twisted together with the weaving yarns, and any of the warps and the wefts. A knitting structure is formed in which the X-ray contrast yarn is substantially parallel to either one of the warp and the weft, and the weft yarn of the gauze main body alternately from the front side of the X-ray contrast yarn It was hung on the back side .
[0006]
Then, the X-ray contrast yarn interweaves with one of the warp and the weft while the X-ray contrast yarn is twisted together with the weaving yarn in the gauze body that is plain-woven by alternately intersecting the warp and weft of the cotton to form a flat structure. By forming a twisted structure in which the yarn is substantially parallel to either the warp or the weft, the weaving yarn is entangled with the X-ray contrast yarn, and the X-ray contrast yarn is prevented from falling off.
[0007]
The gauze according to claim 2 is the gauze according to claim 1, wherein the woven yarn is cotton yarn.
[0008]
By using cotton yarn as the weaving yarn, the weaving yarn has the same quality as the warp and weft constituting the gauze body, the appearance is improved, and the warp and weft can be used as the weaving yarn, thereby improving the productivity.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the gauze of the present invention will be described with reference to the drawings.
[0010]
In FIG. 1, 1 is a gauze, and this gauze 1 has a gauze body 4 having a plain structure in which cotton warp yarns 2 and weft yarns 3 are alternately crossed and plain woven. In the gauze body 4, the X-ray contrast yarn 5 is woven into the weft 3 by weaving while being twisted with the weaving yarn 6 that is the same quality and the same shape as the warp yarn 2.
[0011]
That is, the X-ray contrast yarn 5 is located between the adjacent warp yarns 2 and 2 on the surface side, which is one surface side of the gauze body 4 having a flat tissue, and the weaving yarn 6 for knitting weave alternately from the front side of the X-ray contrast yarn 5 The gauze 1 is stretched over the back side of the weft 3 of the gauze body 4, and the gauze 1 has a plain structure composed of warps 2, 2 and wefts 3, 3, and a twisted structure composed of an X-ray contrast yarn 5 and a weaving yarn 6. ing.
[0012]
The X-ray contrast yarn 5 is produced by impregnating barium sulfate with a fibrous resin such as polypropylene, polyvinyl chloride, or silicon. Further, the X-ray contrast yarn 5 is thicker and less flexible than the warp yarn 2, the weft yarn 3 and the woven yarn 6 due to its characteristics. For this reason, the woven X-ray contrast yarn 5 is substantially linear, the gauze 1 is linear, the X-ray contrast yarn 5 is substantially parallel to the warp yarn 2 of the gauze body 4, and the woven yarn 6 is the X-ray contrast yarn 5. A crease structure that is entangled with each other is formed.
[0013]
As described above, the gauze 1 is formed by weaving the X-ray contrast yarn 5 and the weaving yarn 6 into the gauze body 4 having a plain weave structure, so that the structure of the entire gauze 4 is a plain structure, and the characteristics of the gauze 1 are changed. Without this, the pull-out resistance becomes extremely large as compared with the gauze 10 in which the conventional X-ray contrast yarn 5 is plain-woven, and the X-ray contrast yarn 5 can be prevented from falling off.
[0014]
For this reason, the X-ray contrast thread 5 can be fixed and provided without falling off without using an additive such as an adhesive in the gauze 1 used for medical treatment such as being used in the body for surgery.
[0015]
Further, when the gauze body 4 is also woven, the warp yarn 2 and the weft yarn 3, which are cotton yarns, are thin and not rigid, so there is a risk that the yarn will come close. However, the gauze body 4 is a conventional flat tissue and an X-ray contrast yarn 5 Therefore, the X-ray contrast yarn 5 does not fall out, the function of the conventional gauze 10 can be maintained, and it can be formed in a cross shape without being affected by the weaving method.
[0016]
And since the X-ray contrast thread | yarn 5 does not fall out, the presence or absence of the gauze 1 can be confirmed reliably by X-ray imaging.
[0017]
In addition, the knitting weave is a quaternary structure aligned with a plain weave, and can be formed by a generally used weaving method. Therefore, as described above, the process is not complicated and can be easily formed as in the conventional gauze 10.
[0018]
Furthermore, since the yarn 6 having the same quality and the same shape as the warp 2 is used for the weaving yarn 6 that also binds to the X-ray contrast yarn 5, only the X-ray contrast yarn 5 is woven into the gauze body 4, and the appearance is improved and the weaving yarn. The warp 2 can be used as 6, it is not necessary to use a different kind of weaving yarn 6, the productivity can be improved, and the function as the gauze 1 can be improved as compared with the case of using a different type of weaving yarn.
[0019]
In the above embodiment, the X-ray contrast yarn 5 may be formed of any material having X-ray contrast properties.
[0020]
Further, when forming the gauze 1, the X-ray contrast yarn 5 and the weaving yarn 6 are woven, or the X-ray contrast yarn 5 and the weaving yarn 6 are woven into the gauze body 4 formed by plain weaving in advance by weaving by weaving. Also good.
[0021]
The weaving yarn 6 is not limited to the same quality and shape as the warp yarn 2, and a different yarn may be used.
[0022]
Then, the X-ray contrast yarn 5 is positioned substantially parallel to the warp yarn 2 and woven with the weft yarn 3 while being woven with the weft yarn 6, but may be positioned substantially parallel to the weft yarn 3 and woven with the warp yarn 2.
[0023]
【Example】
Next, an experimental example of the gauze according to the above embodiment will be described.
[0024]
The warp yarn 2 and the weft yarn 3 constituting the gauze body 4 were about 453.59 [g] × about 768.10 [m] × 40, which is 40th. The gauze 1 is a plain weave with a standard width of 30 + 5 [cm] and 30-1.0 [cm] with a length of 12 ± 1 [pieces] and 12 ± 1 [sides] in 1 cm2. is there. The obtained gauze 1 was cut into a length of 300 mm and a width of 50 mm to obtain a sample piece. The X-ray contrast yarn 5 has a length dimension of 200 mm. Further, as the X-ray contrast yarn 5, one having a composition of 39% polypropylene resin, 60% barium sulfate, and 1% of other additives was used.
[0025]
And the sample piece was hold | maintained so that the chuck | zipper space | interval of the measuring apparatus which is not shown in figure might be set to 200 mm, the X-ray contrast thread 5 was pulled with the pulling speed of 300 mm / min, and the tensile load was measured. In addition, the conventional gauze 10 which plain-woven the X-ray contrast yarn 5 was used as a comparative sample. The results are shown in Table 1.
[0026]
[Table 1]
Figure 0003658308
From the results shown in Table 1, the gauze 1 of the present example formed by weaving the X-ray contrast yarn 5 and the weaving yarn 6 into the plain weave structure gauze body 4 by plain weaving, the conventional X-ray contrast yarn 5 was plain-woven. As compared with the gauze 10, the drawing resistance of the X-ray contrast yarn 5 is about 20 times more, and it can be seen that the X-ray contrast yarn 5 is very difficult to come off.
[0027]
【The invention's effect】
According to the gauze according to claim 1, since the warp and weft of the cotton alternately intersect with each other to form a twisted structure, the weaving thread is X It becomes in a state of being entangled with the radiographic thread, and can prevent the X-ray contrast thread from falling off.
[0028]
According to the gauze of the second aspect, in addition to the effect of the gauze of the first aspect, since the cotton yarn is used as the woven yarn, the woven yarn has the same quality as the warp and weft constituting the gauze main body, and the appearance can be improved. The warp and the weft can be used as the above, and the productivity can be improved.
