TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gauze provided with an X-ray contrast member.
[0002]
[Prior art]
Generally, in a surgical operation or the like, a gauze is used to absorb blood, a body fluid, or the like of a subject. This type of gauze is removed from the body of the patient after the operation is completed.However, the gauze stains the blood of the patient and makes it difficult to distinguish it from the organs of the patient. There is a risk of suturing accidentally while remaining in the body.
[0003]
For this reason, a gauze provided with an X-ray contrast thread is used so that it is possible to confirm whether or not the gauze is left in the body of the subject by performing X-ray imaging of the operated part after the operation. Have been.
[0004]
Conventionally, this type of woven gauze or non-woven gauze is provided with one X-ray contrast yarn per gauze.
[0005]
Furthermore, this type of gauze includes a gauze main body in which cotton warps and wefts are alternately crossed and plain-woven, and one x-ray contrast yarn and one weaving yarn are kinked on this gauze main body with each other. For example, a configuration in which a weaving structure that is woven into a weft and substantially parallel to a warp is formed is known. As a result, this gauze makes it difficult for the X-ray contrast thread to fall out of the gauze main body, and facilitates confirmation of the gauze during X-ray imaging (for example, see Patent Document 1).
[0006]

[0007]
[Problems to be solved by the invention]
However, in the above-described gauze, although the X-ray contrast yarn is woven into the gauze main body, the X-ray contrast yarn can be prevented from falling off from the gauze main body. When hidden in a complicated skeletal part, or when it overlaps with a calcified organ, the sharpness in X-ray imaging may be reduced and confirmation may not be easy.
[0008]
In addition, when a gauze having a small size is used, the X-ray contrast yarn itself becomes short, and it is not easy to confirm the X-ray image.
[0009]
Furthermore, a configuration in which the X-ray contrast thread is thickened to improve the sharpness during X-ray imaging is also conceivable. However, the rigidity of the X-ray contrast thread increases, so that the rigidity of the gauze increases, and the organ of the surgical subject increases. May be damaged.
[0010]
Then, it is conceivable to increase the density of the X-ray contrast agent mixed in the X-ray contrast yarn to improve the sharpness at the time of X-ray imaging. However, if the concentration of the X-ray contrast agent is increased, the X-ray contrast agent is increased. The resin constituting the yarn becomes brittle and breaks, or it is difficult to form the yarn.
[0011]
The present invention has been made in view of such a point, and an object of the present invention is to provide a gauze that suppresses rigidity, maintains a texture, and can be easily confirmed at the time of X-ray imaging.
[0012]
[Means for Solving the Problems]
The gauze according to claim 1, a warp and a weft alternately intersect with each other, and a plainly woven gauze body having both longitudinal edges and lateral edges is provided. And a plurality of X-ray contrast members arranged substantially parallel to each other along any one direction.
[0013]
And, since a plurality of X-ray contrast members are arranged parallel to each other along at least one of the longitudinal direction and the lateral direction on the gauze body woven plainly by alternately intersecting the warp and the weft, manufacturing is easy. In addition, for example, the X-ray contrast member can be easily confirmed at the time of X-ray imaging without increasing the thickness of the X-ray contrast member or increasing the amount of the X-ray contrast agent contained in the X-ray contrast member. The rigidity of the gauze can be suppressed, the strength of the X-ray contrast member can be prevented from lowering, and the texture of the gauze can be maintained.
[0014]
The gauze according to claim 2 is a gauze main body formed of a nonwoven fabric in a shape having both ends in the vertical direction and both side edges in the horizontal direction, and the gauze main body is arranged along at least one of the vertical direction and the horizontal direction. And a plurality of X-ray contrast members arranged substantially in parallel with each other.
[0015]
And, since a plurality of X-ray contrast members are arranged on the gauze body in the gauze body formed of a nonwoven fabric, production becomes easy, and for example, the X-ray contrast member is made thicker, and the X-ray contrast member is included. The X-ray contrast member can be easily confirmed at the time of X-ray photography without increasing the amount of the X-ray contrast agent, and the gauze texture is suppressed by suppressing the rigidity of the gauze and preventing a decrease in the strength of the X-ray contrast member. It is possible to keep.
[0016]
According to a third aspect of the present invention, there is provided the gauze according to the first or second aspect, wherein the X-ray contrast member includes an X-ray contrast agent and a resin, and is compression-bonded to the gauze body.
[0017]
Then, by pressing the X-ray contrast member to the gauze main body, the manufacturing becomes easier as compared with, for example, weaving or sandwiching the X-ray contrast member in the gauze main body, and the X-ray contrast member has a required length. , And manufacturing costs can be reduced.
[0018]
A gauze according to a fourth aspect is the gauze according to the first or second aspect, wherein the X-ray contrast member includes an X-ray contrast agent and a solvent, and is applied to the gauze body.
[0019]
Then, by forming the X-ray contrast member with the X-ray contrast agent and the solvent and applying the X-ray contrast member to the gauze main body, the manufacturing becomes easier as compared with a case where the X-ray contrast member is woven or sandwiched in the gauze main body, for example. At the same time, it becomes possible to dispose a required amount of X-ray contrast members, and the manufacturing cost is suppressed. In addition, since the rigidity of the gauze main body can be suppressed as compared with a case where a thread-shaped X-ray contrast member is inserted into the gauze main body, the feeling is improved.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the gauze of the present invention will be described with reference to FIG.
[0021]
In FIG. 1, reference numeral 1 denotes a gauze. The gauze 1 has a substantially rectangular flat structure in which warp 2 and weft 3 are plainly woven alternately and crosswise and have both longitudinal edges and lateral edges. Gauze body 4.
[0022]
Here, the warp 2 and the weft 3 are, for example, cellulose fibers such as cotton and rayon, or a mixture of cellulose fibers and plastic fibers such as polypropylene and polyester.
[0023]
In the gauze body 4, a plurality of, for example, two X-ray contrast yarns 5 as X-ray contrast members are spaced apart from each other and woven in parallel with the warp 2.
[0024]
The X-ray contrast yarn 5 is obtained by mixing, for example, about 60% of barium sulfate with a fibrous resin molded of, for example, polyvinyl chloride, polypropylene, polyester, polyethylene, polystyrene, or silicone. It is. The X-ray contrast yarn 5 is thicker and less flexible than the warp 2 and the weft 3 due to its characteristics. For this reason, the woven X-ray contrast yarn 5 is substantially linear.
[0025]
The interval between the X-ray contrast yarns 5 is preferably about 2 to 30 mm.
[0026]
As described above, according to the above-described embodiment, a plurality of X-ray contrast yarns 5 are arranged in parallel with each other in the longitudinal direction on the gauze main body 4 in which the warp yarns 2 and the weft yarns 3 are alternately crossed and plain-woven. Since the X-ray contrast thread 5 is provided, for example, the X-ray contrast thread 5 can be easily confirmed at the time of X-ray imaging without increasing the thickness of the X-ray contrast thread 5 or increasing the amount of the X-ray contrast agent contained in the X-ray contrast thread 5. At the same time, it is possible to suppress the rigidity of the gauze 1 and prevent the strength of the X-ray contrast yarn 5 from decreasing, thereby maintaining the texture of the gauze 1.
[0027]
Further, by setting the interval between the X-ray contrast yarns 5 to about 2 to 30 mm, two X-ray contrast yarns within a relatively narrow range can be obtained at the time of X-ray imaging of the operated part of the subject after the operation. Since the image 5 is photographed, the gauze 1 can be easily confirmed when the gauze 1 is left in the body of the operation subject.
[0028]
Further, since the X-ray contrast yarns 5 are not in contact with each other, the warp yarns 2 and the weft yarns 3 constituting the gauze 1 exist between these X-ray contrast yarns 5, so that the X-ray contrast yarns 5 from the gauze body 4 are not in contact with each other. Missing can be prevented.
[0029]
If the distance between the X-ray contrast yarns 5 is too wide, it is not easy to confirm how many pieces of the gauze 1 are present in the body of the patient during X-ray imaging. By setting the interval to about 2 to 30 mm, the number of the gauze 1 left in the body of the subject during X-ray imaging can be easily confirmed.
[0030]
Further, since the two X-ray opaque yarns 5 are arranged in parallel to the warp yarns 2, the gauze 1 can be made easier than when the X-ray opaque yarns 5 are arranged irrespective of the directions of the warp yarns 2 and the weft yarns 3. Can be manufactured.
[0031]
In the above embodiment, each of the X-ray contrast yarns 5 may be arranged in parallel with the weft 3 as shown in FIG. 2, or as shown in FIG. 3, the warp 2 and the weft 3 May be arranged in parallel with each other. In this case, the same operation and effect as those of the above-described embodiment can be obtained.
[0032]
Further, the fibrous resin constituting the X-ray contrast yarn 5 may be a thermoplastic resin such as polyvinyl chloride, polypropylene, polyethylene, or polystyrene, and the X-ray contrast yarn 5 may be hot-melt-pressed to the gauze body 4. is there. As this method, for example, a method in which a thermoplastic resin mixed with an X-ray contrast agent is melted, disposed while being extruded from a nozzle onto the gauze main body 1, and pressure-bonded by a roll, or an X-ray contrast yarn already formed in a thread shape For example, a method of arranging 5 on the gauze main body 4 and compressing it with a hot roll is possible.
[0033]
In this case, as compared with a case where the X-ray contrast yarn 5 is woven or sandwiched in the gauze body 4, for example, it can be manufactured more easily, and it is not necessary to feed the continuous X-ray contrast yarn 5 and the necessary length is required. Only the gauze body 4 can be provided, and the manufacturing cost can be reduced.
[0034]
Further, the X-ray contrast member may be composed of an X-ray contrast agent and a petroleum organic solvent such as benzene or toluene and applied to the gauze main body 4. In this case, the X-ray imaging member can be easily manufactured as compared with the case where the X-ray imaging member is woven or sandwiched in the gauze main body 4, and the required amount of the X-ray imaging member can be disposed on the gauze main body 4, thereby suppressing the manufacturing cost. it can. Moreover, since the rigidity of the gauze main body 4 can be suppressed as compared with the case where a thread-shaped X-ray contrast member is inserted into the gauze main body 4, for example, the texture can be improved.
[0035]
And the gauze main body 4 may be formed of a nonwoven fabric as shown in FIG. At this time, each of the X-ray contrast yarns 5 is arranged so as to be sandwiched between the nonwoven fabrics in the longitudinal direction of the gauze main body 4 shown in FIG. 4, or in the horizontal direction of the gauze main body 4, or in the horizontal and vertical directions. . In this case, there is no need to weave the X-ray contrast thread 5 into the gauze body 4, and the gauze 1 can be manufactured more easily.
[0036]
Further, the number of X-ray contrast yarns 5 can be set to an arbitrary number of two or more, but if the number is too large, the rigidity of the gauze 1 becomes large. To
[0037]
