Description

  The present invention relates to a disposable sanitary member such as gauze provided with an X-ray contrast yarn and a method for manufacturing the same.

Conventionally, as this type of disposable sanitary member , gauze is used to absorb blood and body fluids in a surgical operation or the like. Although this gauze is removed from the body after surgery, it often becomes stained with blood during surgery, making it difficult to distinguish it from organs, etc., so it is possible to terminate the operation by suturing it while remaining in the body There is sex. For this reason, a gauze provided with an X-ray contrast thread is used during surgery. That is, by performing an X-ray after performing an operation using the gauze in which the X-ray contrast yarn is arranged, the X-ray contrast yarn arranged in the gauze can be contrasted on a radiograph. You can check if there is any leftover from the body at the time of surgery.

  In this type of gauze, one or a plurality of X-ray contrast yarns are arranged for one gauze. Specifically, this type of gauze is configured such that an X-ray contrast yarn is woven by weaving with a warp yarn of a gauze body with a woven yarn, and the X-ray contrast yarn is not easily removed from the gauze body. Further, in this gauze, the X-ray contrast yarn is disposed between both ends in the longitudinal direction of the gauze body, and the X-ray contrast yarn has the same length as the warp of the gauze body. A configuration that protrudes outward is known (see, for example, Patent Document 1).

Furthermore, this type of gauze is constructed so that a plurality of X-ray contrast yarns can be replaced with one warp thread of the gauze body and plain weave so that the X-ray contrast yarns can be reliably confirmed during X-ray imaging. . Further, in this gauze, the X-ray contrast yarn is disposed between both ends in the longitudinal direction of the gauze body, and the X-ray contrast yarn has the same length as the warp of the gauze body. Projecting outwards. Further, since the X-ray contrast yarn of this gauze is formed to a certain thickness so that it can be easily confirmed at the time of X-ray imaging, a configuration having higher rigidity than the warp and weft of the gauze body is known (for example, (See Patent Document 2).

  However, in the above-described gauze, since both ends of the X-ray contrast yarn are the same length as the warp and are located outward from the gauze body, the X-ray contrast yarn may be picked by mistake. There is a possibility that this X-ray contrast thread may be cut off halfway when it is picked and pulled. Furthermore, since this X-ray contrast yarn is formed to have higher rigidity than the warp and weft of the gauze body, the X-ray contrast yarn is in contact with the gauze body at a portion located outside the gauze body of the X-ray contrast yarn. There is a problem that there is a possibility of damaging a contact object such as a body or skin.

  This invention is made | formed in view of such a point, and it aims at providing the disposable hygiene member which an X-ray contrast thread cannot pick easily, and cannot damage a to-be-contacted object, and its manufacturing method.

The disposable sanitary member according to claim 1 is a sanitary material in which a plurality of warps along the longitudinal direction and a plurality of wefts along the width direction are alternately cross-woven, and along the longitudinal direction of the sanitary material. A disposable sanitary member that is arranged to intersect with the wefts and has a warp of this sanitary material and an X-ray contrast yarn having higher rigidity than each of the wefts, at both ends in the longitudinal direction of the sanitary material , The weft stoppers are formed so that the weft yarns are densely arranged in contact with each other along the longitudinal direction, and the weft yarns are disposed outward of the sanitary material in the longitudinal direction from the weave stoppers. stopped but is being woven stopper outer part no is formed disposed, the X-ray opaque filament has two ends,, and is located inside the end portion of the warps of the weave retaining outer portion, the weave Outside the weft located at the outer edge of the section Only in those protruding.

A plurality of warp yarns along the longitudinal direction and a plurality of weft yarns along the width direction cross alternately with the weft yarns along the longitudinal direction of the sanitary material plain woven, and the warp yarns and weft yarns of this sanitary material X-ray contrast yarns having higher rigidity are disposed. Further, at both ends of the sanitary material in the longitudinal direction, weaving stoppers are formed in which a plurality of wefts are arranged in contact with each other along the longitudinal direction so that the wefts are dense. Further, the outer side of the sanitary material in the longitudinal direction is formed with a weaving outer portion where no weft is disposed. Then, both end portions of the X-ray opaque filament, along with being position inwardly from the end portions of the weaving stop the outward portion warp protrudes outward from the weft yarn located on the outer edge of the weaving stop portion . For this reason, since it becomes difficult to pick both ends of this X-ray contrast thread, this X-ray contrast thread is not picked, and when this X-ray contrast thread is picked and pulled, it is prevented from being cut halfway. it can. In addition, since the portion of the X-ray contrast yarn that protrudes from the outer portion of the X-ray contrast yarn is reduced, it is possible to prevent the contacted object that contacts both ends of the X-ray contrast yarn from being damaged.

The disposable sanitary member according to claim 2 is a sanitary material in which a plurality of warps along the longitudinal direction and a plurality of wefts along the width direction are alternately cross-woven, and along the longitudinal direction of the sanitary material. Disposable sanitary members that are arranged so as to intersect with the weft yarns and have an X-ray contrast yarn having higher rigidity than each of the warp yarns and the weft yarns of the sanitary material, and at both ends in the longitudinal direction of the sanitary material, The weft stoppers are formed so that the weft yarns are densely arranged in contact with each other along the longitudinal direction, and the weft yarns are disposed outward of the sanitary material in the longitudinal direction from the weave stoppers. There is being woven stopper outer part no is formed disposed, the X-ray opaque filament is one that is located between the outer edge and the inner edge of the retaining portion both end portions weave.

A plurality of warp yarns along the longitudinal direction and a plurality of weft yarns along the width direction cross alternately with the weft yarns along the longitudinal direction of the sanitary material plain woven, and the warp yarns and weft yarns of this sanitary material X-ray contrast yarns having higher rigidity are disposed. Further, at both ends of the sanitary material in the longitudinal direction, weaving stoppers are formed in which a plurality of wefts are arranged in contact with each other along the longitudinal direction so that the wefts are dense. Further, the outer side of the sanitary material in the longitudinal direction is formed with a weaving outer portion where no weft is disposed. Since both ends of the X-ray contrast yarn are located between the outer edge and the inner edge in the width direction of the weaving stopper, both ends of the X-ray contrast yarn are not located at the outer portion of the weaving stopper. . For this reason, it can prevent reliably picking up this X-ray contrast thread, and can prevent reliably that the to-be-contacted object which contacts the both ends of this X-ray contrast thread is damaged.

According to a third aspect of the present invention, there is provided a method for manufacturing a disposable sanitary member, the step of arranging an X-ray contrast yarn in parallel along the transport direction together with a plurality of warps, and A plurality of wefts are alternately crossed so that the wefts are densely arranged so that the wefts are in close contact with each other along the longitudinal direction, and the warps and the wefts are alternately crossed. a plain weave has been flat woven portion, and the woven stopper portion, the steps of said weft threads outwardly stop weaving not disposed portion is sequentially continuous sanitary material which is formed continuously in the carrying direction repeatedly formed , with both end portions of the front Symbol X-ray opaque filament is positioned more on the inner side end portion of the warp stop outward portion weaving the, outward from the weft yarn positioned outside the edge of the woven stopper portion or by cutting the X-ray opaque filament so as to project It is intended to cut along the respective weaving stop outward portion each of the warp in the width direction of the sanitary materials.

Then, X-ray contrast yarns are arranged in parallel along the transport direction together with a plurality of warps. Thereafter, a plurality of wefts were alternately crossed in a direction perpendicular to the conveying direction of these warps and X-ray contrast yarns, and a plurality of wefts were arranged in contact with each other along the longitudinal direction so that the wefts became dense. A sanitary material in which a weaving stop, a plain weaving part in which warps and wefts are alternately crossed, a plain weaving part, a weaving stopping part, and a weaving outer part where no weft is arranged are successively formed Are continuously and repeatedly formed in the conveying direction . Furthermore, as both ends of the X-ray opaque filament, along with being located from the end of the weaving stop the outward portion warps inward projecting outward from the weft yarn located on the outer edge of the weaving stop portion Cut the X-ray contrast thread. As a result, both end portions of the X-ray opaque filament, along with being position inwardly from the end portions of the weaving stop the outward portion warp, projecting outward from the weft yarn located on the outer edge of the weaving stop portion A disposable sanitary member can be manufactured easily and continuously. Therefore, it is difficult to pick both ends of the X-ray contrast yarn, and it is possible to easily manufacture a disposable sanitary member that can prevent an object to be in contact with the both ends of the X-ray contrast yarn from being damaged.

According to disposable sanitary member according to claim 1, wherein both ends of the X-ray opaque filament, along with being position inwardly from the end portions of the weaving stop the outward portion warp, positioned outside the edge of the woven stopper portion Since it protrudes outward from the weft , both ends of the X-ray contrast thread can be difficult to pick, so that it can be prevented from being cut off halfway when this X-ray contrast thread is picked and pulled. Since the portion of the X-ray contrast yarn that protrudes to the outside of the weave is reduced, it is possible to prevent the contacted object from being damaged at both ends of the X-ray contrast yarn.

According to disposable sanitary member according to claim 2, wherein, since the position between the outer edge and the inner edge in the width direction of the stopper portion weave both ends of the X-ray opaque filament, to pluck the X-ray opaque filament Can be reliably prevented, and the contacted object can be reliably prevented from being damaged at both ends of the X-ray contrast yarn.

According to the manufacturing method of disposable hygiene member according to claim 3, wherein both ends of the X-ray opaque filament, along with being position inwardly from the end portions of the weaving stop the outward portion warps, weaving stop portion of the outer edge The disposable sanitary member protruding outward from the weft located at the position can be easily and continuously manufactured, so that both ends of the X-ray contrast yarn are difficult to pick, and the contacted object is placed at both ends of the X-ray contrast yarn. A disposable sanitary member that can be prevented from being damaged can be easily manufactured.

  Next, the structure of 1st Embodiment of the disposable sanitary member of this invention is demonstrated with reference to FIG. 1 and FIG.

  1 and 2, 1 is a gauze as a disposable sanitary member. This gauze 1 is a disposable sanitary material containing an X-ray contrast yarn, and is used for absorbing blood, body fluid, or the like for surgery such as surgery or for medical purposes. The gauze 1 includes a gauze body 4 as a sanitary material, which is formed by alternately weaving straight warps 2 and wefts 3 into a plain weave.

  Here, each of the warp 2 and the weft 3 of the gauze body 4 was spun linearly with a material such as cotton, cellulose fibers such as rayon, or a mixture of cellulose fibers and plastic fibers such as polypropylene or polyester. It is formed into a thread.

  Specifically, the gauze body 4 includes a plurality of warp yarns 2 that are spaced apart in parallel along the longitudinal direction and a plurality of weft yarns 3 that are spaced apart in parallel along the width direction. It has a rectangular plain weave portion 5 configured to intersect and plain weave. The plain weave portion 5 is formed by plain weaving a plurality of warp yarns 2 and a plurality of weft yarns 3 alternately intersecting at equal intervals.

  A plurality of, for example, about six wefts 3 are arranged in contact with each other along the longitudinal direction so that the wefts 3 are densely arranged at both end edges as both ends along the longitudinal direction of the plain weave portion 5. Each of the constructed weaving stoppers 6 is formed. The weave stoppers 6 are formed by weaving a plurality of wefts 3 alternately intersecting with each of the warp yarns 2 at narrower intervals than the interval between the warp yarns 2.

  Furthermore, wefts 3 are not provided on both side edges, which are both ends along the longitudinal direction of the plain weave part 5 of the weave stoppers 6, and only the warp 2 protrudes outward from the weave stoppers 6. Stopping outer portions 7 are respectively formed. These outer weave stoppers 7 are provided outward in the longitudinal direction of the plain weave 5 from the outer edge of each weave stopper 6. Further, these outer weave stoppers 7 are formed at the end 8 of each warp 2 that protrudes outward from the weft 3 woven into the outer edge of the weave stopper 6.

Thus, each warp yarn 2 of the gauze body 4 is disposed over the outer edge of one of the weaving stop outer portion 7 of the gauze body 4 to the outer edge of the other weaving stop outward portion 7. Further, these warp yarns 2 are alternately woven and woven between the wefts 3 over the entire region in the width direction of the plain weave portion 5 of the gauze body 4.

  Furthermore, these wefts 3 are arranged from one side edge to the other side edge in the width direction of the plain weave portion 5 of the gauze body 4. Further, these wefts 3 are woven by alternately plain weaving between the warp yarns 2 from the outer edge of one weave stopper 6 of the gauze body 4 to the outer edge of the other weave stopper 6.

  The gauze body 4 is provided with an X-ray contrast yarn 11 that can be contrasted with an X-ray image obtained by X-ray imaging. As shown in FIG. 1, the X-ray contrast thread 11 is attached to a position closer to one side in the width direction of the gauze body 4 in plan view. Further, the X-ray contrast thread 11 is a filament formed as a single continuous thread, and has a certain thickness so that it can be easily confirmed during X-ray imaging. Accordingly, the X-ray contrast yarn 11 is formed with higher rigidity than each of the warp yarn 2 and the weft yarn 3 of the gauze body 4.

  Further, the X-ray contrast thread 11 is formed by forming a thread from an X-ray contrast medium and a plastic resin. Here, as an X-ray contrast agent, barium sulfate or the like is used as a material. As the plastic resin, polyvinyl chloride, polypropylene, polyester, polyethylene, polystyrene, silicone, or the like is used.

Specifically, the X-ray contrast yarn 11 is disposed such that both longitudinal ends 12 of the X-ray contrast yarn are located on the inner side of the longitudinal ends of each warp 2 of the gauze body 4. Yes. Further, as shown in FIG. 2, both end portions 12 of the X-ray contrast thread 11 are positioned on the inner side of the outer edge of the weaving outer portion 7 formed at each end portion in the longitudinal direction of the gauze body 4. In addition, it protrudes slightly outward from the weft 3 located at the outer edge of the weave stopper 6 provided inside each of the outer weave stoppers 7. In addition, the X-ray contrast yarn 11 is woven so as to alternately cross each weft 3 of the gauze body 4 in a state where any one warp 2 of the gauze body 4 is replaced.

  Next, the manufacturing method of the disposable sanitary member of the first embodiment will be described with reference to FIG.

  First, as step 1, a single linear X-ray contrast yarn 11 along with a plurality of straight warp yarns 2 is conveyed, and the warp yarn 2 and the X-ray contrast yarn 11 are conveyed. They are spaced apart from each other in parallel along the flow direction.

Next, as step 2, a plurality of warps 2 and X-ray contrast yarns 11 are crossed alternately while being spaced apart in parallel in a direction orthogonal to the flow direction of each of the plurality of warp yarns 2 and X-ray contrast yarns 11, 6, the gauze body 4 in which the plain weave part 5, the weave stopper 6 and the weave outer part 7 are successively formed in succession is repeatedly formed continuously in the flow direction to form the connected gauze 1. .

Further, as step 3, both end portions 12 of the X-ray contrast yarn 11 are located on the inner side of the end portion 8 of the warp 2 of the weaving outer portion 7 and from the weft 3 located on the outer edge of the weaving portion 6. After cutting the X-ray contrast yarn 11 so as to protrude outward, the warp yarns 2 of the respective weaving outer portions 7 of the gauze 1 continuously connected in the flow direction are cut along the width direction. Thus, the gauze 1 containing the X-ray contrast yarn 11 is manufactured.

As described above, according to the first embodiment, the length of the gauze body 4 in which a plurality of warp yarns 2 along the longitudinal direction and a plurality of weft yarns 3 along the width direction alternately intersect and are plain woven. An X-ray contrast yarn 11 having higher rigidity than each of the warp 2 and the weft 3 of the gauze body 4 is disposed so as to cross the weft 3 along the direction. Further, at both ends of the gauze body 4 in the longitudinal direction, weaving stoppers 6 each having a plurality of wefts 3 arranged in contact with the longitudinal direction so that the wefts 3 are dense are formed. On the outer side of the gauze body 4 in the longitudinal direction from the stop portion 6, a weave stop outer portion 7 in which the weft 3 is not disposed is formed. Then, both end portions 12 of the X-ray opaque filament 11, along with being position inwardly from the end portion of the warp yarn 2 of the retaining outer portion 7 weave, outward from the weft 3 which is located outside the edge of the woven stopping part 6 It was set as the structure which protruded toward .

As a result, both end portions 12 of the X-ray contrast yarn 11 are located on the inner side of the weave stop outer portion 7 of the gauze body 4 and outward of the weft 3 located on the outer edge of the weave stop portion 6. since protrudes toward less likely knob only both end portions 12 of the X-ray opaque filament 11. Therefore, since it is possible to prevent only the X-ray contrast thread 11 from being picked by mistake, when the end 12 of the X-ray contrast thread 11 is picked and pulled, the X-ray contrast thread 11 is cut off halfway. Can be prevented. At the same time, the portions protruding from the weave stopper 6 of the both ends 12 of the X-ray contrast thread 11 to the outer weave stopper 7 can be reduced. It is possible to prevent the contacted object such as the body and skin from being damaged, and to prevent the occurrence of itching caused by rubbing the end 12 of the X-ray contrast thread 11 against the skin.

Further, the X-ray contrast yarns 11 are arranged in parallel with the plurality of warps 2 along the flow direction, and then the plurality of wefts 3 are alternately arranged perpendicular to the flow directions of the warp yarns 2 and the X-ray contrast yarns 11. The gauze body 4 in which the weave stopper 6, the plain weave 5, the weave stopper 6 and the weave outer part 7 are successively formed in succession in the flow direction, Let it be a concatenated gauze 1. Thereafter , both end portions 12 of the X- ray contrast yarn 11 are located on the inner side of the end portion 8 of the warp 2 of the weave stopper outer portion 7 and outward of the weft yarn 3 positioned on the outer edge of the weave stop portion 6. After cutting the X-ray contrast yarn 11 so as to protrude toward the end, the warp yarns 2 of the respective weaving outer portions 7 of the gauze 1 continuously connected in the weaving flow direction of the gauze 1 in the width direction It was set as the structure which continuously cuts the several gauze 1 cut | disconnected along and cut | disconnected individually.

As a result, the weft 3 at both ends 12 of the X-ray opaque filament 11, along with being position inwardly from the end portion 8 of the warp yarn 2 of the retaining outer portion 7 each weave, which is located outside the edge of the woven stopping part 6 The gauze 1 containing the X-ray contrast yarn 11 protruding outward can be easily and continuously manufactured. Therefore, it is difficult to pick both ends 12 of the X-ray contrast thread 11, and the gauze 1 containing the X-ray contrast thread 11 can be easily prevented from being damaged by contact of both ends 12 of the X-ray contrast thread 11. Can be manufactured.

In the first embodiment, the end portion 12 of the X-ray contrast yarn 11 is slightly protruded from the weft 3 located at the outer edge of the weaving stop portion 6 of the gauze body 4, but the second embodiment shown in FIG. As in the embodiment, both end portions 12 of the X-ray contrast yarn 11 can be positioned inwardly of the weft yarns 3 positioned at the outer edges of the weave stoppers 6 of the gauze body 4. The both end portions 12 of the X-ray contrast yarn 11 are arranged so as to overlap a plurality of, for example, the fourth warp yarns 2 counted from the outer edge of each weave stopper 6 of the gauze body 4. Therefore, the X-ray contrast yarn 11 has the gauze body 4 so that both ends 12 of the X-ray contrast yarn 11 are located between the outer edge and the inner edge of the outer weave 7 of the gauze body 4. Is woven into.

As a result, both ends 12 of the X-ray contrast yarn 11 are located between the outer edge and the inner edge in the width direction of the weave stopper 6, so that both ends 12 of this X-ray contrast thread 11 are not weaved. It is no longer located in the side part 7. For this reason, it is possible to more reliably prevent the X-ray contrast thread 11 from being picked, and it is possible to more reliably prevent the body and skin from being damaged by both end portions 12 of the X-ray contrast thread 11. It is possible to more reliably prevent itching from occurring at the end 12 of the contrast thread 11.

That is, both end portions 12 of the X-ray contrast yarn 11 may be located inside the both end portions 8 of the warp yarn 2, but the end portions 8 of the warp yarn 2 and the end portions 12 of the X-ray contrast yarn 11 may be located. When the difference is small, the effect that the both end portions 12 of the X-ray contrast yarn 11 are difficult to pick is not obtained so much. It is preferable to position it. Further, both end portions 12 of the X-ray opaque filament 11, considering that to prevent inadvertent this X-ray opaque filament 11, and the outer edge is the length hands outward portion of the gauze body 4 in the weaving stop section 6 It is preferable that it is located between the inner edge which is a longitudinally inner part.

  In addition, although one X-ray contrast thread 11 is woven into the gauze body 4, in order to make this X-ray contrast thread 11 easily imaged by X-ray photography, a plurality of X-ray contrast threads 11 are gathered into one gauze. The plurality of X-ray contrast threads 11 can be woven into the gauze body 4 separately.

Further, the X-ray contrast yarn 11 is cut so that both end portions 12 of the X-ray contrast yarn 11 are located on the inner side of the end portion 8 of the warp 2 of the weaving outer portion 7, and then continuously connected in the flow direction. It has been but each weaving stop outward portions 7 each warp yarn 2 of gauze 1 was cut along the width direction, after cutting the retaining outer portion 7 of each warp yarn 2 weave each moth over peptidase 1, gauze body 4 A plurality of gauze 1 cut individually can also be manufactured continuously by cutting the X-ray contrast yarns 11 woven into the yarn separately.
