Description

【0001】
【発明の属する技術分野】
本発明は、手術時に使用されるX線造影糸を具備する医療用ガーゼに係り、特にそのX線造影糸が簡単に抜け落ちないように構成された医療用ガーゼに関するものである。
【0002】
【従来の技術】
従来、医療従事者が外科手術等の手術を行う場合、患者からの出血,体液等の拭き取り及び吸収を行うため、大きさが例えば30cm×30cmのガーゼを多数枚使用する必要がある。そして手術後には、手術を行った医療従事者によって使用されたガーゼは、全て患者の体内から除去されることとなる。この時、手術中に使用されたガーゼは出血により赤く染まり、手術時の切開部において患者の臓器とガーゼとが目視により識別しにくくなるため、ガーゼが手術後の患者の体内に残ってしまう虞がある。もしこのように手術後の患者の体内にガーゼを取り残してしまった場合、患者の体内にガーゼが残存し続けると、その患者は違和感を覚えるだけでなく、身体に痛みを伴う、あるいは発熱する等の異状が患者に発生する虞がある。そこで医療従事者は、手術後の患者の体内にガーゼを取り残さないよう、手術時に使用した全てのガーゼを除去しなければならない。
【0003】
そこで上記のことを鑑み、主に手術で使用されるガーゼとしては、ガーゼを構成する多数の構成糸の内の一本を、例えば硫酸バリウムを含有するシリコン系樹脂から成るX線造影糸に置き換えて図3のように該X線造影糸を織り込んだ医療用ガーゼが一般的に採用されている。この図3に示される従来のガーゼでは、一本のX線造影糸と多数の経糸はほぼ等間隔に織り込まれ、また多数の緯糸についても、X線造影糸および多数の経糸と略直交する方向にほぼ等間隔に織り込まれている。
【0004】
このような一本のX線造影糸が織り込まれて成るガーゼにより、従来は手術時におけるガーゼの除去作業を行った後、手術の施術箇所をX線撮影することで、医療従事者は、このX線造影糸を目印としてガーゼの取り残しがないかを確認していた。またガーゼの取り残しがあった場合には、医療従事者は、このX線造影糸を目印として取り残しガーゼの位置を正確に認識し、このガーゼの除去作業を行っていた。以上のようにして、手術時に使用された全てのガーゼを除去する作業が行われていた。
【0005】
【発明が解決しようとする課題】
しかしながら、このX線造影糸の表面は非常に滑らかであるため、従来のガーゼでは、医療行為中にガーゼからX線造影糸が簡単に抜け落ちてしまうことがあった。このようにX線造影糸がガーゼから簡単に落ちてしまうようでは、取り残しのガーゼを探し出すための目印としてのX線造影糸の役割が果たされないため、従来のガーゼを用いて手術を行った後に施術箇所のX線撮影を行ったところで、医療従事者は、取り残しガーゼの存在有無および取り残しガーゼの位置を正確に認識することができないといった不都合が生じる虞があった。
【0006】
そこで上記の問題点を解決するために、ガーゼを構成する繊維糸にX線造影糸を融着させ、X線造影糸がガーゼから抜け落ちないようにすることが考えられる。しかしながら、繊維糸とX線造影糸との融着部分は固化しているため、このガーゼの使用時あるいはガーゼが患者の体内に取り残された場合に、患者により一層の違和感を与えるのみならず、この固化した融着部分が施術箇所に接触することによって、その接触箇所が傷付いてしまう虞がある。
【0007】
以上より本発明の目的は、上記の問題点を改善し、医療行為中にX線造影糸が簡単に抜け落ちることなく、また取り残しガーゼの存在有無および取り残しガーゼの残存位置の確認を医療従事者が正確に行えるようにし、且つ患者に対する安全性が確保された医療用ガーゼを提供することである。
【0008】
【課題を解決するための手段】
上記目的を達成するため、本発明は、多数の緯糸と,該緯糸と略直交する多数の経糸とを構成糸とする医療用ガーゼにおいて、前記構成糸の内の少なくとも一本をX線造影糸とし、該X線造影糸に対して略直交方向に且つほぼ等間隔に該X線造影糸と交差する構成糸は、一本置きにX線造影糸の上面側と下面側とを交差し、且つこのX線造影糸と接触し、さらに前記X線造影糸に対して略平行方向の構成糸の内、前記X線造影糸の両側に近接する複数本の構成糸は、お互いが接触し且つX線造影糸とも接触するように密に織り込まれて構成されている。
【0009】
また本発明の医療用ガーゼにおいて、前記X線造影糸に対して略平行方向の構成糸の内、前記X線造影糸の両側に密に織り込まれる構成糸の本数を、それぞれ2本以上4本以下とすることによって、上記目的を達成することができる。更には前記X線造影糸に対して略平行方向の構成糸の内、前記X線造影糸の両側に接触する二本の構成糸を偏平状とし、該X線造影糸と面接触するように織り込むことで、上記目的を達成することができる。
【0010】
【発明の実施の形態】
以下、本発明の一実施形態における医療用ガーゼについて、図1及び図2を参照して説明する。図1は本発明の一実施形態における医療用ガーゼの全体構成図であり、図2は本実施形態の医療用ガーゼにおけるX線造影糸近傍の構成を示す拡大構成図である。
【0011】
本実施形態における医療用ガーゼ1は、ガーゼの構成糸である多数の緯糸4と経糸2の内、多数の経糸2の内の一本をX線造影糸5に置き換え、該X線造影糸5を経糸2および緯糸4と共に織り込んで構成されている。ここで、本発明のガーゼを構成するX線造影糸5と各緯糸4とは、図2のように交絡した状態となっている。具体的には、各緯糸4はX線造影糸5に対して略直交方向に且つほぼ等間隔に該X線造影糸5と交差しているが、これらの各緯糸4は、一本置きにX線造影糸5の上面側と下面側とを交差し、且つこのX線造影糸5と接触している。尚、本実施形態では経糸2の内の一本をX線造影糸5に置き換えているが、緯糸4の内の一本をX線造影糸5に置き換えてもよく、また、置換するX線造影糸の本数は本実施形態では一本としているが、これに限定されるわけではない。
【0012】
また、この医療用ガーゼ1を構成する経糸2の交絡状態について図2を参照して説明すると、本実施形態の医療用ガーゼ1では、X線造影糸5の近傍における経糸3の密度が、このX線造影糸5近傍以外の部分における経糸2の密度に比べて非常に高い構成となっている。具体的には、X線造影糸5および該X線造影糸5の両側に近接する複数本(本実施形態ではそれぞれ4本)の経糸3は、それぞれ隣接するX線造影糸5あるいは経糸3a,3Aと互いに接触する程度に密に織り込まれており、X線造影糸5近傍以外の部分における各経糸2(即ち、上記複数本の経糸3以外の経糸2)は、従来と同様に、ほぼ等間隔に且つ各緯糸4に対して略直交方向に織り込まれている。
【0013】
以上のように構成された医療用ガーゼ1では、多数の緯糸4がX線造影糸5のガーゼ上面側とガーゼ下面側とで等間隔に且つ交互に交差,接触しているため、X線造影糸5が抜け落ちる際にX線造影糸5の表面には、これらの交差,接触する多数の緯糸4によって、ガーゼからX線造影糸5を抜け落ちる方向と反対方向に抵抗力(摩擦力)が生じる。この抵抗力により、ガーゼからX線造影糸5が容易に抜け落ちにくくなる。
【0014】
また、このX線造影糸5の両側の経糸3が緯糸4と共に密に織り込まれることにより、X線造影糸5と交差する各緯糸4が、図4に示すようにX線造影糸5近傍において固定されるような状態となるため、X線造影糸5が抜け落ちる際に、各緯糸4がX線造影糸5の抜け落ちる方向にずれてしまうことがない。これより、上記のような各緯糸4から発生する抵抗力は、X線造影糸5の表面に確実に伝達することが可能となる。
【0015】
さらに、X線造影糸5の両側に接触する経糸3Aは、上記の多数の緯糸4と同様、X線造影糸5が抜け落ちる際にX線造影糸5の表面に、ガーゼからX線造影糸5が抜け落ちる方向と反対方向に抵抗力(摩擦力)が生じる。ここで、このX線造影糸5の両側の最近接の経糸3Aは、該X線造影糸5の側面と所々で接触した状態となるので、これら最近接の経糸3AとX線造影糸5との間には、上記の多数の緯糸4により生じる抵抗力よりも大きい抵抗力が生じることとなる。また、このX線造影糸5近傍の両側にある複数本の経糸3は密に織り込まれているため、図2のように隣接するX線造影糸5と該X線造影糸5近傍の経糸3a,3Aとが互いに接触し、X線造影糸5の最近接経糸3Aの位置がずれることがない。これより、医療従事者が手術等でこの医療用ガーゼ1を使用する際に、X線造影糸5の両側の最近接経糸3Aが該X線造影糸5の表面から離れることなく、接触した状態が保たれる。つまり、X線造影糸5の表面に上記抵抗力を確実に発生させることができる。
【0016】
このように、従来のガーゼではX線造影糸5が該ガーゼから抜け落ちてしまっていた状態でも、本発明の医療用ガーゼ1では、X線造影糸5の表面に、交差,接触する多数の緯糸4からのみならず、X線造影糸5の両側にて接触する最近接経糸3Aからも上述のような抵抗力が生じることとなる。よって、医療従事者が手術等の医療行為中にガーゼを使用している最中に、この医療用ガーゼ1からX線造影糸5が容易に抜け落ちることはない。
【0017】
また本発明の医療用ガーゼ1におけるX線造影糸5は、簡単に抜け落ちないようにガーゼに融着されてはいないので、上述のように固化した融着部分によって患者が一層の違和感を覚えたり、患者の体内で融着部分が接触した箇所が傷付く虞がない。以上のことから、本発明の医療用ガーゼ1によれば、患者に対する安全性も確保されることとなる。
【0018】
尚、本実施形態では、X線造影糸5の両側で密に織り込まれる経糸3の本数をそれぞれ4本としているが、このX線造影糸5の両側にある最隣接の経糸3Aの位置がずれないように経糸3a,3Aが密に織り込まれていれば、本数は任意に設定可能である。ここで、本発明者らは、本実施形態の医療用ガーゼにおいて、密に織り込まれた経糸の本数とX線造影糸の抜け落ちにくさとの関係について調査し、最良の本数を求めるべく次のような実験を行った。以下、この実験方法及び得られた結果について説明する。
【0019】
まず、実験に使用した医療用ガーゼの構成糸たる経糸及び緯糸には綿糸40番手(約453.5g×約768.10m×40)のものを選定した。また、X線造影糸の組成は、ポリプロピレン樹脂約39%,硫酸バリウム約60%,その他の添加剤約1%とした。以上の構成糸およびX線造影糸から成る実験用のガーゼは、1cmにつき経糸12±1本,緯糸12±1本の条数とし且つガーゼの標準幅を縦30cm(誤差+0.5cm),横30cm(誤差−0.5cm)として平織りされて成り、さらにX線造影糸の両側に密に織り込まれる経糸の本数を後述の表1に示すように2本ずつ,2本と3本,3本ずつ,4本ずつとする4種類の試験片ガーゼを用意した。
【0020】
次に、上記構成の各種試験片ガーゼおよび図3のような従来のガーゼ(従来品)においてX線造影糸がガーゼから抜ける際に該X線造影糸の表面に発生する引抜き抵抗力を、各種試験片ガーゼおよび従来品について引張試験機を用いた引張荷重試験により測定した。この引抜き抵抗力の測定方法は、まず引張試験機に備わる一対のチャックの内、一方のチャックによりX線造影糸を保持すると共に、他方のチャックによりX線造影糸を挟まないような状態でガーゼを保持する。この時、引張荷重測定装置におけるチャック間距離を300mmとする。続いて、引張速度300mm/分でチャックを作動させ、X線造影糸をガーゼから前記引張速度で引き抜き、その時に生じる引張荷重を測定する。以上のようにして各種試験片ガーゼおよび従来品において生じる引抜き抵抗力の測定を行い、表1に示す測定値を得た。以下にこの実験による測定結果を表1に示す。
【0021】
【表1】

Figure 0003648727
【0022】
表1によれば、X線造影糸の両側に密に織り込まれる複数の経糸の本数を2本以上に設定すると、ガーゼからX線造影糸が抜け落ちる方向とは反対方向に働く抵抗力が大きくなってX線造影糸が抜け落ちにくくなるという効果が発生し、上記経糸の本数を増加させるにつれてその効果は大きくなることが判る。また、X線造影糸の両側に密に織り込まれる経糸の本数を4本ずつとすると、X線造影糸は抜け落ちる前に破断に至っている。
【0023】
ここで、本数を4本ずつとした場合にX線造影糸の破断が起こっていることを鑑みると、次のことが言える。まず3本ずつ以下の場合では、X線造影糸は従来品に比べてかなり抜け落ちにくくなるが、多少なりとも抜け落ちてしまう可能性は存在する。次に4本ずつに設定した場合には、X線造影糸が抜け落ちることなく破断してしまう程の引抜き抵抗力が生じている。また、密に織り込まれる経糸の本数を5本以上とした場合には、当然の事ながらX線造影糸は破断することとなり、またこの際に生じる引抜き抵抗力は実質的に4本ずつに設定した場合と同じになると言えるため、密に織り込まれる経糸の本数を4本ずつに設定することが、X線造影糸が抜け落ちないという効果を達成するには最も好ましいと言える。
【0024】
また、密に織り込まれる経糸の本数を多くすると、糸の使用本数が多くなってコストアップになると共に、X線造影糸近傍が硬くなってしまうためにガーゼ自体の柔らかさが失われるといった不都合が生じてしまう。以上のことを上記測定結果と合わせて鑑みると、本発明の医療用ガーゼにおいてX線造影糸の両側に密に織り込まれる複数本の経糸の本数は、それぞれ2本以上4本以下に設定することが好ましく、更にはX線造影糸の両側に4本ずつ密に織り込まれることが最良であると結論付けることができ、密に織り込まれる複数本の経糸の本数をそれぞれ2本以上4本以下に設定された医療用ガーゼによれば、医療行為中にガーゼからX線造影糸が簡単に抜け落ちなくなる。
【0025】
尚、上記実施形態の医療用ガーゼ1において、緯糸4の間隔を狭くすればする程、X線造影糸5の表面に交差,接触する緯糸4の数が増えるため、ガーゼからX線造影糸5を抜け落ちる方向と反対方向に抵抗力(摩擦力)がより大きくなり、その結果ガーゼからX線造影糸5が一層抜け落ちにくくなる。
【0026】
また、上記実施形態の医療用ガーゼ1において、X線造影糸5の両側に接触する二本の最近接経糸3Aに偏平状の糸を使用することで、この経糸3Aは、該X線造影糸5の側面と所々で面接触することが可能となるため、経糸3AとX線造影糸5との間には、より一層大きな抵抗力が生じることとなる。よって、X線造影糸5の両側に接触する二本の最近接経糸3Aとして偏平状の糸を使用すれば、さらに医療用ガーゼ1からX線造影糸5が抜け落ちにくくなる。
【0027】
【発明の効果】
以上述べたように、本発明の医療用ガーゼによれば、X線造影糸が簡単に抜け落ちることがなくなるため、医療従事者が手術後にX線撮影をする等して取り残しガーゼの存在有無および取り残しガーゼの残存位置の確認を確実に行うことができる。また、この医療用ガーゼには固化した部分が存在しないため、固化部分によって患者が一層の違和感を覚えたり、患者の体内において固化部分が接触することにより該接触箇所が傷付くこともなく、患者に対する安全性も確保されたものとなっている。

BACKGROUND OF THE INVENTION
The present invention relates to a medical gauze provided with an X-ray contrast yarn used during surgery, and more particularly to a medical gauze configured so that the X-ray contrast yarn does not easily fall off.
[0002]
[Prior art]
Conventionally, when a medical worker performs an operation such as a surgical operation, it is necessary to use a large number of gauze having a size of, for example, 30 cm × 30 cm in order to wipe and absorb bleeding and body fluid from a patient. After the operation, all gauze used by the medical staff who performed the operation is removed from the patient's body. At this time, the gauze used during the operation is dyed red due to bleeding, and it becomes difficult to visually distinguish between the patient's organ and the gauze at the incision at the time of the operation, so the gauze may remain in the patient's body after the operation. There is. If the gauze is left in the patient's body after surgery in this way, if the gauze continues to remain in the patient's body, the patient not only feels uncomfortable, but also causes pain in the body or fever, etc. May occur in patients. Therefore, the medical staff must remove all the gauze used at the time of the operation so as not to leave the gauze in the patient's body after the operation.
[0003]
In view of the above, as a gauze mainly used in surgery, one of a number of constituent yarns constituting gauze is replaced with, for example, an X-ray contrast yarn made of a silicon-based resin containing barium sulfate. As shown in FIG. 3, a medical gauze in which the X-ray contrast yarn is woven is generally employed. In the conventional gauze shown in FIG. 3, one X-ray contrast yarn and a large number of warps are woven at substantially equal intervals, and a large number of wefts are substantially perpendicular to the X-ray contrast yarns and a large number of warps. Are woven into almost equal intervals.
[0004]
Conventionally, after performing a gauze removal operation at the time of surgery with a gauze in which such a single X-ray contrast yarn is woven, a medical worker can take this operation by taking an X-ray image. It was confirmed that there was no gauze left over using the X-ray contrast yarn as a mark. In addition, when there is any remaining gauze, the medical staff has left this X-ray contrast thread as a mark, accurately recognizes the position of the gauze, and has performed the removal work of this gauze. As described above, an operation for removing all the gauze used at the time of surgery has been performed.
[0005]
[Problems to be solved by the invention]
However, since the surface of the X-ray contrast yarn is very smooth, in the conventional gauze, the X-ray contrast yarn may easily fall out of the gauze during medical practice. If the X-ray contrast thread easily falls off the gauze in this way, the role of the X-ray contrast thread as a mark for searching for the remaining gauze is not fulfilled, so surgery was performed using conventional gauze. When X-ray imaging of the treatment site was performed later, there was a risk that the medical staff would not be able to accurately recognize the presence or absence of the left gauze and the position of the left gauze.
[0006]
Therefore, in order to solve the above problems, it is conceivable to melt the X-ray contrast yarn from the gauze by fusing the X-ray contrast yarn to the fiber yarn constituting the gauze. However, since the fused portion of the fiber yarn and the X-ray contrast yarn is solidified, not only does the patient feel more uncomfortable when using this gauze or when the gauze is left in the patient's body, When this solidified fusion part contacts the treatment site, the contact site may be damaged.
[0007]
From the above, the object of the present invention is to improve the above-mentioned problems, so that the medical staff can confirm the presence / absence of the remaining gauze and the remaining position of the remaining gauze without causing the X-ray contrast yarn to easily fall out during medical practice. It is an object of the present invention to provide a medical gauze that can be accurately performed and is safe for patients.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a medical gauze comprising a large number of wefts and a large number of warps substantially orthogonal to the wefts, wherein at least one of the constituent yarns is an X-ray contrast yarn. And the constituent yarns that intersect the X-ray contrast yarn in a substantially orthogonal direction and at substantially equal intervals to the X-ray contrast yarn intersect the upper surface side and the lower surface side of the X-ray contrast yarn every other line, And a plurality of constituent yarns adjacent to both sides of the X-ray contrast yarn among the constituent yarns in contact with the X-ray contrast yarn and in a direction substantially parallel to the X-ray contrast yarn are in contact with each other; It is configured to be closely woven so as to be in contact with the X-ray contrast yarn.
[0009]
In the medical gauze according to the present invention, the number of constituent yarns that are closely woven on both sides of the X-ray contrast yarn among the constituent yarns in a direction substantially parallel to the X-ray contrast yarn is 2 or more and 4 respectively. The said objective can be achieved by setting it as follows. Further, of the constituent yarns in a direction substantially parallel to the X-ray contrast yarn, the two constituent yarns that come into contact with both sides of the X-ray contrast yarn are made flat and are in surface contact with the X-ray contrast yarn. The above purpose can be achieved by weaving.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a medical gauze according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is an overall configuration diagram of a medical gauze according to an embodiment of the present invention, and FIG. 2 is an enlarged configuration diagram illustrating a configuration in the vicinity of an X-ray contrast yarn in the medical gauze according to the present embodiment.
[0011]
The medical gauze 1 in the present embodiment replaces one of the multiple wefts 4 and warps 2 that are constituent yarns of the gauze with the X-ray contrast yarn 5, and the X-ray contrast yarn 5. Are woven together with the warp 2 and the weft 4. Here, the X-ray contrast yarn 5 and each weft 4 constituting the gauze of the present invention are in an entangled state as shown in FIG. Specifically, each weft 4 intersects the X-ray contrast yarn 5 in a direction substantially orthogonal to the X-ray contrast yarn 5 and at substantially equal intervals. The upper surface side and the lower surface side of the X-ray contrast yarn 5 intersect and are in contact with the X-ray contrast yarn 5. In the present embodiment, one of the warps 2 is replaced with the X-ray contrast yarn 5. However, one of the wefts 4 may be replaced with the X-ray contrast yarn 5, and the X-ray to be replaced The number of contrast threads is one in this embodiment, but is not limited to this.
[0012]
Further, the entangled state of the warp 2 constituting the medical gauze 1 will be described with reference to FIG. 2. In the medical gauze 1 of the present embodiment, the density of the warp 3 in the vicinity of the X-ray contrast yarn 5 is The density is very high compared to the density of the warp 2 in the portion other than the vicinity of the X-ray contrast yarn 5. Specifically, the X-ray contrast yarn 5 and a plurality of (four in this embodiment) warp yarns 3 adjacent to both sides of the X-ray contrast yarn 5 are respectively adjacent X-ray contrast yarns 5 or warps 3a, The warp yarns 2 are closely woven so as to come into contact with each other 3A, and the warp yarns 2 (that is, the warp yarns 2 other than the plurality of warp yarns 3) in portions other than the vicinity of the X-ray contrast yarn 5 are substantially equal as in the prior art. They are woven at intervals and in a direction substantially orthogonal to each weft 4.
[0013]
In the medical gauze 1 configured as described above, a large number of wefts 4 intersect and contact each other at equal intervals alternately on the gauze upper surface side and the gauze lower surface side of the X-ray contrast yarn 5. When the yarn 5 falls off, the surface of the X-ray contrast yarn 5 generates a resistance force (friction force) on the surface opposite to the direction in which the X-ray contrast yarn 5 falls off from the gauze due to the crossing and contacting many wefts 4. . This resistance force makes it difficult for the X-ray contrast yarn 5 to easily come off from the gauze.
[0014]
Further, the warp yarns 3 on both sides of the X-ray contrast yarn 5 are densely woven together with the weft yarn 4, so that each weft 4 intersecting the X-ray contrast yarn 5 is in the vicinity of the X-ray contrast yarn 5 as shown in FIG. Since the X-ray contrast yarn 5 falls off, the wefts 4 are not displaced in the direction in which the X-ray contrast yarn 5 falls off because the X-ray contrast yarn 5 falls off. Thus, the resistance force generated from each weft 4 as described above can be reliably transmitted to the surface of the X-ray contrast yarn 5.
[0015]
Further, the warp yarn 3A that contacts both sides of the X-ray contrast yarn 5 is placed on the surface of the X-ray contrast yarn 5 when the X-ray contrast yarn 5 falls off, like the above-mentioned many wefts 4, from the gauze to the X-ray contrast yarn 5 A resistance force (frictional force) is generated in the direction opposite to the direction in which the ink drops off. Here, since the closest warp 3A on both sides of the X-ray contrast yarn 5 is in contact with the side surface of the X-ray contrast yarn 5 in some places, the closest warp 3A and the X-ray contrast yarn 5 In the meantime, a resistance force larger than the resistance force generated by the multiple wefts 4 is generated. Further, since the plurality of warp yarns 3 on both sides in the vicinity of the X-ray contrast yarn 5 are densely woven, the adjacent X-ray contrast yarn 5 and the warp yarn 3a in the vicinity of the X-ray contrast yarn 5 as shown in FIG. , 3A are in contact with each other, and the position of the closest warp 3A of the X-ray contrast yarn 5 is not displaced. Thus, when a medical worker uses the medical gauze 1 for an operation or the like, the closest warp yarns 3A on both sides of the X-ray contrast yarn 5 are in contact with each other without leaving the surface of the X-ray contrast yarn 5 Is preserved. That is, the resistance force can be reliably generated on the surface of the X-ray contrast yarn 5.
[0016]
Thus, even in the state where the X-ray contrast yarn 5 has fallen off from the gauze in the conventional gauze, in the medical gauze 1 of the present invention, a large number of wefts that cross and contact the surface of the X-ray contrast yarn 5. The resistance force as described above is generated not only from 4 but also from the closest warp 3A that contacts on both sides of the X-ray contrast yarn 5. Therefore, the X-ray contrast yarn 5 does not easily fall out of the medical gauze 1 while the medical staff is using the gauze during a medical action such as surgery.
[0017]
Further, since the X-ray contrast yarn 5 in the medical gauze 1 of the present invention is not fused to the gauze so as not to easily fall off, the patient may feel further discomfort due to the fused portion solidified as described above. There is no possibility that the part where the fused part comes in contact with the patient's body is damaged. From the above, according to the medical gauze 1 of the present invention, patient safety is also ensured.
[0018]
In this embodiment, the number of warp yarns 3 densely woven on both sides of the X-ray contrast yarn 5 is set to four, but the position of the nearest warp 3A on both sides of the X-ray contrast yarn 5 is shifted. If the warps 3a and 3A are densely woven so as not to be present, the number can be arbitrarily set. Here, in the medical gauze according to the present embodiment, the present inventors investigate the relationship between the number of closely woven warp yarns and the difficulty of falling off the X-ray contrast yarns, and determine the best number as follows. Such an experiment was conducted. Hereinafter, this experimental method and the obtained results will be described.
[0019]
First, the warp and weft which are the constituent yarns of the medical gauze used in the experiment were selected as cotton yarn 40th (about 453.5 g × about 768.10 m × 40). The composition of the X-ray contrast yarn was about 39% polypropylene resin, about 60% barium sulfate, and about 1% other additives. The experimental gauze composed of the above-described constituent yarns and X-ray contrast yarns has a number of warps of 12 ± 1 and a weft of 12 ± 1 per 1 cm 2 , and a standard width of the gauze is 30 cm in length (error +0.5 cm). As shown in Table 1 below, two warps, two, three, and three, as shown in Table 1 below, are formed by plain weaving as 30 cm in width (error -0.5 cm) and further densely woven on both sides of the X-ray contrast yarn. Four types of test piece gauze were prepared, one for each and four for each.
[0020]
Next, in the various test piece gauze having the above-described configuration and the conventional gauze (conventional product) as shown in FIG. 3, when the X-ray contrast yarn is pulled out from the gauze, various pulling resistance forces are generated on the surface of the X-ray contrast yarn. The test piece gauze and the conventional product were measured by a tensile load test using a tensile tester. The method of measuring the pulling resistance force is to first hold the X-ray contrast yarn by one chuck of the pair of chucks provided in the tensile tester, and keep the X-ray contrast yarn not by the other chuck. Hold. At this time, the distance between chucks in the tensile load measuring device is set to 300 mm. Subsequently, the chuck is operated at a pulling speed of 300 mm / min, the X-ray contrast yarn is pulled out from the gauze at the pulling speed, and the tensile load generated at that time is measured. As described above, the resistance to pulling generated in various test piece gauze and conventional products was measured, and the measured values shown in Table 1 were obtained. The measurement results of this experiment are shown in Table 1 below.
[0021]
[Table 1]
Figure 0003648727
[0022]
According to Table 1, when the number of the plurality of warps closely woven on both sides of the X-ray contrast yarn is set to 2 or more, the resistance force acting in the direction opposite to the direction in which the X-ray contrast yarn falls from the gauze increases. It can be seen that the X-ray contrast yarn is less likely to fall off, and that the effect increases as the number of warps increases. Further, if the number of warp yarns densely woven on both sides of the X-ray contrast yarn is four, the X-ray contrast yarn reaches breakage before falling off.
[0023]
Here, in view of the fact that the X-ray contrast yarn breaks when the number is four, the following can be said. First, in the case of three or less, the X-ray contrast yarn is considerably more difficult to drop than the conventional product, but there is a possibility that the X-ray contrast yarn will fall off somewhat. Next, when the number is set to four, the drawing resistance force is generated so that the X-ray contrast yarn breaks without falling off. In addition, when the number of warp yarns densely woven is 5 or more, the X-ray contrast yarn naturally breaks, and the pulling resistance force generated at this time is set to substantially four. Therefore, it can be said that it is most preferable to set the number of warp yarns to be densely woven to 4 pieces in order to achieve the effect that the X-ray contrast yarn does not fall out.
[0024]
Further, if the number of warp yarns densely woven is increased, the number of yarns used increases and the cost increases, and the vicinity of the X-ray contrast yarn becomes hard, so that the softness of the gauze itself is lost. It will occur. Considering the above together with the above measurement results, the number of the plurality of warps closely woven on both sides of the X-ray contrast yarn in the medical gauze of the present invention should be set to 2 or more and 4 or less, respectively. It can be concluded that it is best to densely weave four on each side of the X-ray contrast yarn, and the number of the plurality of warp yarns densely woven is 2 or more and 4 or less, respectively. According to the set medical gauze, the X-ray contrast yarn does not easily fall out of the gauze during medical practice.
[0025]
In the medical gauze 1 of the above-described embodiment, as the distance between the wefts 4 becomes narrower, the number of wefts 4 that intersect and contact the surface of the X-ray contrast yarn 5 increases. The resistance force (frictional force) becomes larger in the direction opposite to the direction in which the X-ray contrast line 5 falls off, and as a result, the X-ray contrast yarn 5 becomes more difficult to fall out from the gauze.
[0026]
Further, in the medical gauze 1 of the above embodiment, by using flat yarns for the two closest warp yarns 3A that are in contact with both sides of the X-ray contrast yarn 5, the warp yarn 3A can be used as the X-ray contrast yarn. Therefore, even greater resistance is generated between the warp 3A and the X-ray contrast yarn 5. Therefore, if flat yarns are used as the two closest warp yarns 3 </ b> A that are in contact with both sides of the X-ray contrast yarn 5, the X-ray contrast yarn 5 is less likely to fall out of the medical gauze 1.
[0027]
【The invention's effect】
As described above, according to the medical gauze of the present invention, the X-ray contrast yarn does not easily fall off, so that a medical worker performs X-ray photography after the operation and the presence or absence of the left gauze. The remaining position of the gauze can be surely confirmed. In addition, since there is no solidified part in this medical gauze, the patient feels more uncomfortable with the solidified part, and the contacted part is not damaged by the solidified part coming into contact with the patient's body. Safety is also ensured.
