Description

  The present invention relates to a gauze with an X-ray contrast yarn used for medical treatment.

  The gauze with X-ray contrast yarn of Patent Document 1 has a plain weave of warp and weft, and uses the folded end of the weft, the warp of the ear, or a warp close to this as the X-ray contrast yarn. The gauze with an X-ray contrast yarn is used in the human body at the time of surgery. When this gauze remains in the human body, the X-ray contrast thread is reflected on the X-ray photograph and is easy to find.

  The gauze with X-ray contrast yarn of Patent Document 2 has plain warps and wefts, and at least one of the warps is used as an X-ray contrast yarn to prevent the X-ray contrast yarn from coming off. According to Patent Document 2, this retaining is as follows. A plurality of warp yarns adjacent to both sides of the X-ray contrast yarn are closely woven so that they are in contact with each other and also in contact with the X-ray contrast yarn. The number of warp yarns densely woven on both sides of the X-ray contrast yarn is 2 or more and 4 or less, respectively. In addition, the two warp threads contacting both sides of the X-ray contrast yarn are flattened and woven so as to be in surface contact with the X-ray contrast yarn.

[Issues of background technology]
In the gauze with X-ray contrast yarn of Patent Document 1, the warp X-ray contrast yarn is only sandwiched between wefts by a normal plain weave. Easy to escape. If the gauze from which the X-ray contrast thread has fallen off remains in the human body, it will not appear in the X-ray photograph and is difficult to detect.

  In the gauze with an X-ray contrast yarn of Patent Document 2, the warp X-ray contrast yarn is sandwiched between the weft yarns on both sides in the thickness direction by plain weaving, while the weft yarns are densely woven on both sides in the weft direction. In contact.

  However, in the technique of Patent Document 2, in order to prevent the X-ray contrast yarn from coming off, it takes time and effort to closely weave the X-ray contrast yarn and the warp yarns adjacent to both sides so as to contact each other. In addition, the number of warp yarns is increased because the yarns are closely woven to prevent the X-ray contrast yarn from coming off. Manufacturing costs increase.

  Further, the warp X-ray contrast yarn is located in the middle of the gauze weft direction, and the outside of the retaining warp on both sides of the X-ray contrast yarn is a regular plain weave. Both the retaining warp yarn adjacent to one side of the X-ray contrast yarn and the retaining warp yarn adjacent to the other side are shifted from the X-ray contrast yarn to the opposite side of the X-ray contrast yarn side to the normal plain weave portion. May leave. When the retaining warp is separated from the X-ray contrast yarn, the X-ray contrast yarn is easily pulled out.

[Idea for solving problems]
Medical plain weave gauze generally does not densely weave gauze that tightly weaves the warp yarns around the ears on both sides in the weft direction and weft yarns to prevent fraying, and warp yarns near the weft yarn end. There is gauze. In addition, the gauze of patent documents 1 and 2 is the latter gauze which does not densely weave the warp of the ear | edge part.

  The present inventors paid attention to the former gauze and the gauze which closely weaves the warp yarns of the ear part to prevent fraying of the yarn. In this type of gauze, the densely woven warp yarns at the ears were also used to prevent the X-ray contrast yarn from coming off.

  When weaving the gauze fabric, X-ray contrast yarns are mixed as warp yarns into the group of warp yarns that become densely woven ears, and the warp yarn groups of the ears including the X-ray contrast yarns are densely woven to produce X-ray contrast yarns of warp yarns. Are densely woven in the middle of the weft direction of the densely woven warp group of the ear portion, and the densely woven warp yarn of the ear portion is arranged on the weft end side of the X-ray contrast yarn and the opposite side. The X-ray contrast yarn is sandwiched on both sides in the weft direction by densely woven warp yarns at the ears, and the retaining warp yarn is adjacent to both sides in the weft direction.

  This eliminates the trouble of densely weaving warps other than the densely wefted warp yarns for preventing the X-ray contrast yarn from coming off. In addition, the number of warp yarns need not be increased to prevent the X-ray contrast yarn from coming off.

  In addition, the retaining warp adjacent to the weft return end side of the X-ray contrast yarn is different from the retaining warp adjacent to the opposite side of the X-ray contrast yarn. Blocked by the folded end. That is, it is difficult to shift to the opposite side to the X-ray contrast yarn side, and it is difficult to separate from the X-ray contrast yarn. It is halved that the retaining warp yarn is shifted to the opposite side to the X-ray contrast yarn side and the X-ray contrast yarn is easily pulled out. The effect of preventing the X-ray contrast yarn from coming off is high.

  In the above case, the X-ray contrast yarn of the warp is arranged at the middle in the weft direction of the densely woven warp group of the ear part, but is arranged at the edge of the densely woven warp group of the ear part and the edge on the side of the weft end. Then, the X-ray contrast yarn is sandwiched between the weft end of the weft yarn and the densely woven warp yarn of the ear portion, and the close end yarn of the weft yarn and all the densely woven warp yarns of the ear portion are adjacent to each other in the weft direction. The folded end of the weft yarn is added to the densely woven warp yarn at the ear portion to prevent the X-ray contrast yarn from coming off.

  1) Plain weave warp and weft, mix X-ray contrast yarn as warp yarn in the weft yarn group of close-weaving ears near the fold end of the weft, close weave warp yarn group including X-ray contrast yarn, The X-ray contrast yarn of the warp is arranged in the middle of the densely woven warp group of the ear portion or the edge on the side of the fold back of the weft yarn, and the densely woven warp yarn of the ear portion is arranged on the opposite side of the weft end of the X-ray contrast yarn. A method for producing a gauze with an X-ray contrast yarn, characterized by being adjacent to each other.

2) A gauze in which warp yarns and weft yarns are plain woven, and the warp yarns in the ears near the folded end of the weft yarn are densely woven.
X-ray contrast yarns are mixed as warp yarns in the densely woven warp groups of the ears, and the X-ray contrast yarns of the warp yarns are woven into the middle of the close-weaved warp yarn groups of the ears or the edge on the side where the weft ends are folded, X A gauze with an X-ray contrast yarn, characterized in that densely woven warp yarns at the ears are arranged adjacent to each other on the opposite side to the weft return end side of the line contrast yarn.

3) In the gauze with X-ray contrast yarn of 2) above,
The X-ray contrast yarn of the warp is located in the middle of the group of closely woven warp yarns of the ear part, and the closely woven warp yarns of the ear part are adjacently arranged on the opposite side and the opposite side of the weft thread, and both sides in the weft direction. Is sandwiched between closely woven warp yarns at the ears.

4) In the gauze with X-ray contrast yarn of 2) above,
The X-ray contrast yarn of the warp is located at the edge on the weft end side of the group of closely woven warp yarns in the ear part, and the closely woven warp yarn of the ear part is arranged adjacent to the opposite side of the weft end of the weft end, and in the weft direction. It is characterized in that both sides are sandwiched between folded ends of closely woven warp yarns and weft yarns at the ears.

  The trouble of densely weaving warp yarns other than the ears to prevent the X-ray contrast yarn from coming off is saved. There is no need to increase the warp to prevent the X-ray contrast yarn from coming off.

  In addition, when a warp warp yarn is adjacent to the weft return end side of the X-ray contrast yarn, the retaining warp yarn is blocked by the return end of the weft yarn, unlike the retaining warp adjacent to the opposite side. , Difficult to shift to the opposite side to the X-ray contrast yarn side, and difficult to separate from the X-ray contrast yarn. The effect of preventing the X-ray contrast yarn from coming off is high.

[First example (see FIGS. 1 to 5)]
The gauze with an X-ray contrast yarn of this example is for medical use and is used in a human body during surgery.

  In the loom, the gauze base fabric is a 40-th cotton yarn for the warp and weft yarns, and the density of the warp and weft yarns is 12 ± 1 / cm, excluding the densely woven portion, and is about 30 cm wide. Plain weave. At this time, the warp yarn groups of the ears on both sides near the folded end of the weft yarn are each densely woven at the maximum density. X-ray contrast yarns are mixed as warp yarns into the warp yarn group of one ear.

  As shown in Fig. 1, the plain weave base fabric of the gauze with X-ray contrast yarn is a warp densely woven portion 1 for the left and right ears 1 on each side, and the yarn is removed without a weft every about 30 cm in length. The portion 2 is formed, and the weft yarn groups 3 on both sides before and after the thread withdrawal portion 2 are respectively formed into the weft densely woven portion 3. In the densely woven ear portion 1 on one side, an X-ray contrast yarn 4 is woven as a warp yarn at an intermediate position in the weft direction.

  The X-ray contrast yarn 4 is a yarn of a synthetic resin such as polypropylene or polyester containing a contrast agent barium sulfate that does not transmit X-rays. The diameter is about 0.6 to 1 mm, which is thicker than the 40th cotton yarn.

  The plain weave base fabric in which the X-ray contrast yarn 4 is woven into the densely woven ear portion 1 on one side cuts the warp yarn of each thread release portion 2 and the X-ray contrast yarn 4 at an intermediate position, and as shown in FIG. Make an angle shaku gauze.

  The ear part 1 and the warp densely woven part 1 on both sides of the shaku gauze each have a density of the warp yarn 6 that is the maximum density of the plain woven fabric, and the distance between the warp yarns 6 is equal to or less than the diameter of the weft yarn 7. 7 is the minimum distance. The warp yarn 6 and the weft yarn 7 are cotton yarns, yarns that are easily deformed, and are curved or flattened. Therefore, the densely woven warp 6 of the ear 1 may be in contact with the adjacent warp 6 except for the crossing portion of the weft 7. The X-ray contrast yarn 4 is not easily deformed to warp yarn 6, weft yarn 7, and cotton yarn.

  As shown in FIG. 3 to FIG. 5 in an enlarged manner, the one-side ear portion 1 and the warp densely woven portion 1 have the warp X-ray contrast yarn 4 located at the center in the direction of the weft yarn 7. The densely woven warp yarns 6 of the ear portion 1 are arranged adjacent to each other on the side of the X-ray contrast yarn 4 at which the weft yarn 7 is turned back and on the opposite side. The densely woven warps 6 on both sides of the X-ray contrast yarn 4 are each half of all densely woven warps 6 of the ear 1. The X-ray contrast yarn 4 of the warp is sandwiched between densely woven warps 6 of the ear portion 1 on both sides in the direction of the weft 7. Further, the warp X-ray contrast yarn 4 has a large number of wefts 7 alternately contacting and intersecting both sides of the gauze in the thickness direction, the upper side surface and the lower side surface, and both sides in the thickness direction intersect with the many weft yarns 7. It is sandwiched. The densely woven warp yarns 6 on both sides of the X-ray contrast yarn 4 prevent the weft yarn 7 sandwiching the X-ray contrast yarn 4 from loosening. This is used to prevent the X-ray contrast yarn 4 from coming off.

  Unlike the retaining dense weave warp 6 adjacent to the opposite side of the weft yarn 7, the weft yarn 6 adjacent to the weft 7 folding end side of the X-ray contrast yarn 4 is blocked by the folded end of the weft yarn 7. It is difficult to shift to the opposite side to the X-ray contrast thread 4 side, and it is difficult to separate from the X-ray contrast thread 4. The retaining effect of the X-ray contrast yarn 4 is high. In addition, the outside of the close-weaving dense weft warp 6 adjacent to the side opposite to the side where the weft yarn 7 is turned back of the X-ray contrast yarn 4 is a plain coarse weave.

  The same number of retaining weft warp yarns 6 on both sides of the X-ray contrast yarn 4 are used, but the number of retaining weaving warp yarns 6 on the folding end side of the weft yarn 7 is reduced to prevent the weaving yarn 7 on the opposite side of the folding end side. The densely woven warp yarn 6 may be increased. Further, the increase / decrease may be reversed.

[Second Example (see FIGS. 6 to 8)]
The gauze with an X-ray contrast yarn of this example is different from that in the first example in the arrangement position of the warp X-ray contrast yarn 4. The X-ray contrast yarn 4 is located not on the middle of the densely woven ear portion 1 on one side in the direction of the weft yarn 7 but on the edge of the weft yarn 7 folding end side.

  As shown in FIGS. 6 to 8 in an enlarged manner, the ear portion 1 and the warp densely woven portion 1 on one side of the gauze are located at the edge on the side where the weft yarn 7 is turned back. ing. The X-ray contrast yarn 4 is in contact with the outer end of the outer circumferential surface of the circumferential surface, with the folded end of the weft yarn 7 wound spirally. There is no densely woven warp yarn 6 of the ear portion 1 on the side of the X-ray contrast yarn 4 on the side where the weft yarn 7 is turned back, and the turning end of the weft yarn 7 is adjacent. All densely woven warp yarns 6 of the ear portion 1 are arranged adjacent to each other on the opposite side of the X-ray contrast yarn 4 from the side where the weft yarn 7 is turned back. The X-ray contrast yarn 4 is sandwiched between all densely woven warp yarns 6 and the end of the weft yarn 7 at both ends in the direction of the weft yarn 7. In addition, the X-ray contrast yarn 4 is folded between a large number of weft yarns 7 in contact with the outer half circumference of the circumferential surface and is sandwiched between the many weft yarns 7.

  As in the first example, the densely woven warp yarn 6 on the opposite side of the end of the weft yarn 7 from the X-ray contrast yarn 4 prevents the weft yarn 7 sandwiching the X-ray contrast yarn 4 from loosening. The number of the densely woven warp yarns 6 is more than that in the first example. The weft thread 7 is wound around a little more than half the circumference of the X-ray contrast thread 4, and the area in contact with the X-ray contrast thread 4 is wider than in the first example. The retaining effect of the X-ray contrast yarn 4 is high.

  Other points are the same as in the first example.
