従来、医療の外科手術分野において、Ｘ線検知エレメントをガーゼに包含させ ることはよく行われている。Ｘ線検知エレメントが包含されたスポンジガーゼは 手術中に不注意で体内に残留された場合にも、後のＸ線撮影で容易に探知するこ とが可能である。 Conventionally, in the field of medical surgery, X-ray detection elements have been incorporated into gauze. This is often done. Sponge gauze containing X-ray detection elements Even if it is inadvertently left inside the body during surgery, it can be easily detected with subsequent X-rays. is possible.
【０００３】 手術用スポンジは通常、尺角及び柄付きガーゼとして使用されるが、手術用折 り込みガーゼ、手術用パッド、線球等も含まれる。 従来、Ｘ線検知エレメントは次のような種々な方法によって、ガーゼ等の手術 用スポンジ材料に取り着けられている。 ガーゼの場合は、Ｘ線検知エレメントのフィラメントがガーゼ布中に織り混ぜ られる、すなわち、縱糸の一部をＸ線検知フィラメントに置き換える方法がある 。さらに、ガーゼ間にＸ線検知エレメントをサンドイッチし、縫い着ける方法が ある。0003 Surgical sponges are usually used as ulnar and handled gauze; This also includes stuffed gauze, surgical pads, line balls, etc. Conventionally, X-ray detection elements have been used to remove surgical objects such as gauze using various methods such as It is attached to a sponge material. In the case of gauze, the filament of the X-ray detection element is woven into the gauze cloth. In other words, there is a method of replacing part of the thread with an X-ray detection filament. . Furthermore, there is a method of sandwiching the X-ray detection element between gauze and sewing it on. be.
【０００４】 又、布の場合は、布の表面にＸ線検知エレメントを熱溶融し、固定して取り着 ける方法がある。そしてさらには、特開昭６２−８２９５６号公報のように、Ｘ 線検知エレメントを含むロービングと熱可溶融性繊維を含む繊維状不織布とをウ オータージェットで絡み合わせ、さらに、その後熱融着させ一体化させる方法も 提案されている。0004 In addition, in the case of cloth, the X-ray detection element is heat-fused to the surface of the cloth and fixed and attached. There is a way to do it. Furthermore, as in Japanese Patent Application Laid-Open No. 62-82956, A roving containing a line detection element and a fibrous nonwoven fabric containing thermofusible fibers are combined. There is also a method of intertwining with autojet and then heat-sealing and integrating. Proposed.
【０００５】 しかしながら、これらの手術用スポンジは様々な問題点を含んでいる。ガーゼ 布中に織り混ぜる場合、ガーゼ自体、短い繊維からなる撚の甘い紡績糸で構成さ れており、尺角などに断裁する工程でＸ線検知エレメントが抜け易く、同時に紡 績糸の毛羽、脱落繊維の発生が多く、手術用スポンジ中に包含されてしまう。 さらに、このような織り混ぜの場合、縫製が必須であり、従って安価に提供す ることに限界がある。[0005] However, these surgical sponges include various problems. gauze When woven into cloth, the gauze itself is made of twisted, sweet spun yarn made of short fibers. The There is a lot of fuzz and fallen fibers in the spinning yarn, which end up being included in the surgical sponge. Furthermore, in the case of such a mixed weave, sewing is mandatory and therefore it is not possible to provide it at low cost. There are limits to what can be done.
【０００６】 布表面にＸ線検知エレメントを熱溶融し、接着固定する方法は加熱によってエ レメントが硬化するし、セルロース系繊維の布との場合は接着力が弱く不充分で ある。そして布の間にサンドイッチし縫い着ける方法は、Ｘ線検知エレメントを 縫針で傷つけることが多く、手間もかかり実用的と言えない。 特開昭６２−８２９５６号公報に開示された方法は、繊維状不織布が短繊維及 び低融点での可溶融性繊維から構成されており、尺角などを製造する際の断裁加 工時に繊維の脱落が生じたり、布表面に毛羽が発生することが多い。又低融点で の、可溶融性繊維はその後の蒸気滅菌時の加圧蒸気でさらに溶融硬化し、皮膚刺 戟性の危険性、さらには皮膚組織を傷つける原因となる危険性が高い。[0006] The method of heat-melting and adhesively fixing the X-ray detection element to the cloth surface is to The element will harden, and if it is attached to cellulose fiber cloth, the adhesive force will be weak and insufficient. be. The method of sandwiching and sewing the X-ray detection element between cloth It is often damaged by sewing needles, is time-consuming, and is not practical. In the method disclosed in JP-A No. 62-82956, the fibrous nonwoven fabric is made of short fibers and It is composed of fusible fibers with a low melting point and is suitable for cutting when manufacturing squares, etc. During processing, fibers often fall off and fluff appears on the fabric surface. It also has a low melting point The fusible fibers are further melted and hardened by pressurized steam during subsequent steam sterilization to prevent skin irritation. There is a high risk of injury and even damage to the skin tissue.

本考案者は接着剤や低融点での可溶融性繊維を用いずに皮膚刺戟性が少なく、 しかも脱落繊維が極めて少ない上、柔軟で強度も高く、安価な手術用不織布スポ ンジを得るため、種々研究した結果本考案に到達した。 すなわち、本考案は、不織布の間に、ヤーン又はモノフィラメントからなるＸ 線検知エレメントが配置された手術用不織布スポンジにおいて、上記不織布が繊 維長５１ｍｍ以上からなり、しかも上記不織布の繊維同士が交絡、一体化されて いることを特徴とするＸ線検知エレメントを備えた手術用不織布スポンジ、であ る。 The inventor of the present invention has created a product with less skin irritation without using adhesives or fusible fibers with a low melting point. In addition, it has extremely low shedding fibers, is flexible, has high strength, and is an inexpensive surgical nonwoven fabric. As a result of various researches, we arrived at this invention. That is, the present invention provides X made of yarn or monofilament between nonwoven fabrics. In a surgical nonwoven sponge in which a line detection element is arranged, the nonwoven fabric is The nonwoven fabric has a fiber length of 51 mm or more, and the fibers of the nonwoven fabric are intertwined and integrated. A non-woven surgical sponge equipped with an X-ray detection element characterized by Ru.
【０００９】 本考案に用いる繊維長５１ｍｍ以上からなる不織布は、海島綿のような繊維長 の長い綿、ビスコースレーヨン、キュプラアンモニュームレーヨン等セルローズ 系繊維及びポリフエニレンテレフタレート繊維、ナイロン６，６６，６Ｔ等のポ リアミド系繊維等の合成繊維、そしてこれらのブレンドからなるものが好ましい 。さらに好ましくは血液吸収性能の高いセルロース系繊維である。[0009] The nonwoven fabric having a fiber length of 51 mm or more used in this invention is a fiber length such as sea island cotton. long cotton, viscose rayon, cupro ammonium rayon, etc. cellulose fibers, polyphenylene terephthalate fibers, nylon 6, 66, 6T, etc. Synthetic fibers such as lyamide fibers and blends of these are preferred. . More preferred are cellulose fibers with high blood absorption performance.
【００１０】 本発明の手術用不織布スポンジに用いる繊維は繊維長が５１ｍｍ以上のもので ある。繊維長が５１ｍｍ以上であれば、脱落繊維が極めて少なく有効である。さ らには１００ｍｍ以上が好ましい。最も好ましいものは連続フィラメントである 。 本考案の手術用不織布スポンジに用いる不織布は予備交絡又は自己接着された 不織布を用いることが好ましい。予備交絡された不織布は移動する孔あきベルト 或はネット上に繊維状ウエブを載置し、２５〜１００ｋｇ／ｃｍ2 の圧力の柱状 水流を作用させて準備されたものが好ましい。The fibers used in the surgical nonwoven sponge of the present invention have a fiber length of 51 mm or more. When the fiber length is 51 mm or more, the number of fallen fibers is extremely small and it is effective. Furthermore, 100 mm or more is preferable. Most preferred are continuous filaments. Preferably, the nonwoven fabric used in the surgical nonwoven sponge of the present invention is a preentangled or self-adhesive nonwoven fabric. The preentangled nonwoven fabric is preferably prepared by placing a fibrous web on a moving perforated belt or net and applying a columnar water stream at a pressure of 25 to 100 kg/cm 2 .
【００１１】 又、自己接着された不織布は特公昭５２−６３８１号公報に開示されているよ うな方法で準備された連続フィラメントのものが好ましい。 本考案に用いる不織布は、繊維長５１ｍｍ以上のもので構成されているので、 容易に絡み合わされることが困難であり、予備交絡又は自己接着されているもの であることが好ましく安価に製造するためにも重要である。[0011] Furthermore, a self-adhesive nonwoven fabric is disclosed in Japanese Patent Publication No. 52-6381. Continuous filaments prepared in this manner are preferred. Since the nonwoven fabric used in this invention is composed of fibers with a length of 51 mm or more, Items that are difficult to entangle easily and are pre-entangled or self-adhesive. This is preferable and also important for manufacturing at low cost.
【００１２】 一体化された手術用不織布スポンジは乾燥重量で約２０〜１５０ｇ／ｍ2 であ ることが好ましい。重量が少ないものは、絡み合わされる度合に限界があり、布 帛強度が低く実用的でない。また、重量が多すぎるものは絡み合わされ度合は充 分だが、繊維密度が高くなり過ぎて硬くなり風合が悪くなる。従って手術用パッ ド等に使用する場合には、これら風合が良好な重量範囲のものを２枚、３枚重ね て使用される。Preferably, the integrated surgical nonwoven sponge has a dry weight of about 20-150 g/m 2 . If the weight is small, there is a limit to the degree of entanglement, and the fabric strength is low, making it impractical. On the other hand, if the weight is too high, the degree of entanglement is sufficient, but the fiber density becomes too high, resulting in hardness and poor feel. Therefore, when used for surgical pads, etc., two or three sheets of these materials with a good feel and weight range are used in layers.
【００１３】 手術用スポンジに用いられる通常のＸ線検知エレメントは、たとえば硫酸バリ ューム等のようなＸ線不透過性充填材料を含むものである。 本考案に用いるＸ線検知エレメントは硫酸バリューム等を充填した高分子樹脂 のヤーン又はモノフィラメントである。 高分子樹脂はポリイソブチレン、ポリ塩化ビニル、そして酢酸ジニルと塩化ビ ニルとの共重合体等が好ましいものである。[0013] Typical X-ray detection elements used in surgical sponges include, for example, sulfuric acid A radiopaque filler material such as a filler material such as a filler material such as a filler material such as The X-ray detection element used in this invention is a polymer resin filled with sulfuric acid barium, etc. yarn or monofilament. Polymeric resins include polyisobutylene, polyvinyl chloride, and dinylacetate and vinyl chloride. A copolymer with Nyl is preferred.
【００１４】 本考案に用いるＸ線検知エレメントは青色、緑色等血液と鮮やかに対照するよ うな色彩に着色されていることが好ましい。この色彩は手術用不織布スポンジ中 のＸ線検知エレメントの存否の認識を容易にすることができる。本発明で不織布 の間にＸ線検知フィラメントが配置されたとは、繊維と接着せず、はさまれ包含 されている状態をいう。[0014] The X-ray detection elements used in this invention are blue, green, and other colors that contrast vividly with blood. It is preferable that it be colored in a bright color. This color is in surgical non-woven sponge The presence or absence of the X-ray detection element can be easily recognized. Non-woven fabric according to the present invention The X-ray detection filament placed between the fibers does not adhere to the fibers, but is sandwiched between them. It refers to the state in which
【００１５】 本考案の手術用不織布スポンジは図１の斜視図に示すようにモノフィラメト （２）（又はヤーン（４））が不織布の間にサンドイッチされているものである 。図２はモノフィラメント（２）がサンドイッチされ、実質的に境目なく交絡、 一体化されている状態を模式的に示す断面図である。不織布（１）及び（３）は 予め交絡又は自己接着された不織布が用いられるが、その後の柱状水流で更に交 絡度合を密にするため、不完全で予備的に交絡又は自己接着されているものであ ることが好ましい。用いる不織布が単にランダム配置或はカードウエブそのまま であれば、交絡が完結するまでに柱状水流処理密度が高くなり過ぎて、Ｘ線検知 エレメントが傷つけられたり、処理速度が遅くなり過ぎたりして工業生産が困難 となる。本考案でいう繊維同士が交絡、一体化されているとは手術用不織布スポ ンジの断面に実質的に熱融着したような境目がなく相互に絡み合っているものを いう。[0015] As shown in the perspective view of Figure 1, the surgical nonwoven sponge of the present invention is a monofilament sponge. (2) (or yarn (4)) is sandwiched between non-woven fabrics . Figure 2 shows that monofilaments (2) are sandwiched and intertwined with virtually no boundaries. FIG. 3 is a cross-sectional view schematically showing an integrated state. Nonwoven fabrics (1) and (3) are A pre-entangled or self-adhesive non-woven fabric is used, which is then further interlaced with a columnar water stream. In order to make the degree of entanglement dense, it is incomplete and pre-entangled or self-adhesive. It is preferable that The nonwoven fabric used is simply a random arrangement or a card web as it is. If so, the density of the columnar water treatment will become too high before the entanglement is completed, making X-ray detection impossible. Industrial production is difficult due to elements being damaged or processing speed becoming too slow. becomes. In this invention, the fibers are intertwined and integrated with each other, which means a surgical non-woven fabric. The cross section of the wire is essentially heat-fused and intertwined with no boundaries. say.
【００１６】 本考案の手術用不織布スポンジは、まず、広巾の不織布として製造され、必要 とされる狭い幅に分割することができるように、Ｘ線検知エレメントが互いに一 定間隔で離間した列として包含されていることが好ましい。製造工程では分割さ れたときの不織布には一本以上のＸ線検知エレメントが流れ方向に、直線的でか つ離間した状態で包含されているものである。[0016] The surgical nonwoven fabric sponge of the present invention is first manufactured as a wide nonwoven fabric, and then The X-ray sensing elements are aligned with each other so that they can be divided into narrow widths. Preferably, they are contained in regularly spaced rows. Separated in the manufacturing process One or more X-ray sensing elements are placed in the nonwoven fabric in a straight line in the flow direction. It is contained in a spaced state.
【００１７】 本考案の手術用不織布スポンジの製造は、Ｘ線検知エレメントを流れ方向に含 む、長尺で広巾のロール状に巻かれた不織布が、まず３０ｃｍ巾に輪切り切断さ れ、ロール状に巻き上げられる。 次いで更に３０ｃｍ長の間隔で切断し、３０×３０ｃｍの尺角の手術用不織布 スポンジとなるようにして作られる。[0017] The manufacturing of the surgical nonwoven sponge of the present invention includes an X-ray detection element in the flow direction. First, a long, wide roll of nonwoven fabric is cut into 30cm wide pieces. and then rolled up into a roll. Next, the surgical nonwoven fabric was further cut into 30 cm long intervals to obtain a 30 x 30 cm square surgical nonwoven fabric. It is made to look like a sponge.
【００１８】 本考案の手術用不織布スポンジは図１に示すように一体化されたＸ線検知エレ メントを含むモノフィラメント（２）を備えた切断しただけの不織布で縫製など の作業を省くことができるものである。 予備交絡又は自己接着された不織布をさらに交絡度合を密にするためには、高 圧の柱状水流を用いるのが好ましい。高圧の柱状水流により、多孔板或はネット の開孔状態に応じ、詰め込まれ密着したり、又、繊維の自由端が絡ったりする。 この場合、Ｘ線検知エレメントを含む不織布はエレメント自体の強度より強く、 繊維が多孔板やネットの開孔状態に応じ、交絡、密着しているので、容易に抜け ることがない不織布が得られる。[0018] The surgical nonwoven sponge of this invention has an integrated X-ray detection element as shown in Figure 1. Sewing with just cut non-woven fabric with monofilament (2) containing It is possible to omit the work of In order to further increase the degree of entanglement of preentangled or self-adhesive nonwoven fabrics, high Preferably, a columnar water stream of pressure is used. A high-pressure columnar water stream is used to clean perforated plates or nets. Depending on the state of the pores, the fibers may be packed tightly together, or the free ends of the fibers may become entangled. In this case, the nonwoven fabric containing the X-ray detection element is stronger than the element itself; The fibers are intertwined and adhered to each other depending on the pores of the perforated plate or net, so they can be easily pulled out. A nonwoven fabric is obtained that does not cause any stains.
