Description

  The present invention relates to a medical gauze in which X-ray contrast yarns are integrally woven.

  2. Description of the Related Art Conventionally, during surgical operations, medical gauze has been used to absorb bleeding and body fluid at a patient's incision. It is necessary to remove all of the gauze after the operation so as not to leave unnecessary foreign matter in the body, but the gauze that has absorbed blood etc. is very difficult to visually recognize and remains in the body by mistake. There was a risk of it.

  Therefore, even if the medical gauze remains in the body, X-ray imaging of the incision part confirms the presence or absence of the remaining medical gauze and accurately grasps the position thereof. There is a medical gauze woven with an X-ray contrast yarn that can remove the gauze. However, the medical gauze simply woven with such an X-ray contrast yarn has a problem that the X-ray contrast yarn made of synthetic resin fibers easily slides out of the gauze main body made of cotton yarn.

  For this reason, a medical gauze that prevents the X-ray contrast thread from falling off has been proposed (see, for example, Patent Document 1). This medical gauze is for an endoscope and includes an X-ray contrast yarn made of an X-ray impermeable thermoplastic resin, and the X-ray contrast yarn is heat-sealed to a yarn constituting the gauze. It is. In addition, a sanitary material with an X-ray contrast thread is also disclosed in which an X-ray contrast thread is used as a sewing thread in a gauze (see, for example, Patent Document 2).

However, these medical gauze increases the number of steps and makes the production method extremely complicated as compared with a conventional gauze production method in which warp and weft are plain woven. Therefore, a medical gauze that can be manufactured by using a conventional gauze manufacturing method and that can reliably prevent the X-ray contrast yarn from falling off from the gauze body is desired.

  The present invention has been made in view of the above points, and can prevent the X-ray contrast yarn from coming off from the medical gauze with a very simple configuration and can be manufactured very easily. A medical gauze is provided.

  Specifically, in the medical gauze in which the warp and the weft are alternately crossed and the X-ray contrast yarn is integrally woven, the reinforcement yarn made of a twisted yarn thicker than the warp and the weft is the X-ray contrast yarn. The present invention relates to a medical gauze which is plain-woven in close contact with one side of a line contrast yarn.

  The invention of claim 2 relates to the medical gauze according to claim 1, wherein the reinforcing yarn is made of cotton or polypropylene resin.

  According to the medical gauze according to the first aspect of the present invention, in the medical gauze in which the warp and the weft are alternately crossed and the X-ray contrast yarn is woven together, the warp and the weft are thicker than the warp. Since the reinforcing yarn is plain-woven in close contact with one side of the X-ray contrast yarn, it is difficult for the X-ray contrast yarn to fall out of the medical gauze. Moreover, it can be manufactured very easily.

  According to the second aspect of the invention, in the first aspect, since the reinforcing yarn is made of cotton or polypropylene resin, it is possible to more reliably prevent the X-ray contrast yarn from falling off.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an overall schematic plan view showing an embodiment of the medical gauze according to the present invention, and FIG. 2 is an enlarged plan view showing a main part of the embodiment of FIG.

  As shown in FIGS. 1 and 2, the medical gauze 10 has warps 14 and wefts 15 alternately intersecting, and an X-ray contrast yarn 18 is woven together. A reinforcing yarn 16 made of a thick twisted yarn is plain-woven in close contact with one side of the X-ray contrast yarn 18.

  The warp yarns 14 and the weft yarns 15 are alternately crossed to form a plain weave gauze body 11. The thickness of the warp yarn 14 and the weft yarn 15 and the size of the gauze body are not particularly limited. In the embodiment, the warp yarn 14 and the weft yarn 15 are made of cotton yarn, and both are 40 counts (the length per unit weight of about 453.5 g). A plain yarn is used with a cotton thread of about 768 m × 40), and the size of the gauze body 11 is about 27 × 27 cm. As shown in the embodiment of FIG. 1, in the medical gauze 10, the warp yarns 14 and the weft yarns 15 are dense at the left and right side end portions 13, 13 and the upper and lower end portions 12, 12 which are the ears of the original fabric. Plain weave.

  The X-ray contrast yarn 18 is woven together with the warp yarn 14 and the weft yarn 15. As the X-ray contrast yarn 18, conventionally known ones are used, and examples thereof include those in which barium sulfate is added to synthetic resin fibers such as polypropylene resin, polyester resin, polyethylene resin, and polyvinyl chloride resin. As understood from the embodiment of FIG. 2, the X-ray contrast yarn 18 has a plurality of synthetic resin fibers constituting the X-ray contrast yarn and other fibers so that the frictional resistance between the reinforcement yarn 16 and the weft yarn 15 is increased. What is twisted with the thread member 19 is preferable. The thread member 19 is made of a synthetic resin fiber such as cotton thread, polypropylene, or polyethylene.

  The reinforcing yarn 16 is a twisted yarn thicker than the warp yarn 14 and the weft yarn 15 and is plain-woven in close contact with one side of the X-ray contrast yarn 18. When the reinforcing yarn 16 is a twisted yarn, the surface of the reinforcing yarn 16 becomes uneven, and the frictional resistance on the contact surface with the weft yarn 15 or the X-ray contrast yarn 18 increases. Therefore, it becomes difficult to slip in the direction of arrow A and arrow B in FIG. Further, since the reinforcing yarn 16 is thicker than the warp yarn 14 and the weft yarn 15, the surface area in contact with the X-ray contrast yarn 18 and the weft yarn 15 orthogonal to the reinforcing yarn 16 (a warp yarn when the reinforcing yarn is parallel to the weft yarn) is large. The friction resistance between the reinforcing yarn 16 and the X-ray contrast yarn 18 and a large number of wefts 15 crossing the upper and lower portions of the reinforcing yarn 16 is increased, and the X-ray contrast yarn 18 is securely held by the reinforcing yarn 16. The X-ray contrast yarn 18 is less likely to slip from the medical gauze 10.

  The reinforcing yarn 16 is a twisted yarn so that a plurality of yarns made of synthetic resin fibers such as cotton, polypropylene resin, polyethylene resin, polyester resin, and polyvinyl chloride resin are thicker than the warp yarn 14 and the weft yarn 15 by a known method. Is done. The reinforcing yarns 16 may all be composed of the same material yarn, or synthetic yarns made of polypropylene resin and cotton yarns are twisted together to form a reinforcing yarn. It may be combined as appropriate to form a twisted yarn. Further, as defined in the invention of claim 2, the reinforcing yarn 16 is preferably made of cotton or polypropylene resin from the viewpoint of difficulty in sliding with the warp yarn 14 and the weft yarn 15 and cost. As an example, for example, when 40th cotton yarn is used as the warp and weft, the reinforcing yarn is 10th (the length per unit weight is about 768 m × 10) and is about 60th (unit). About 2 to 8 cotton yarns having a weight per about 453.5 g and a length of about 768 m × 60) are twisted.

  The reinforcing yarn 16 is plain-woven in close contact with one side of the X-ray contrast yarn 18. As shown in the embodiment of FIGS. 1 and 2, in the medical gauze 10, the surfaces of the reinforcing thread 16 and the X-ray contrast thread 18 are dense over the entire longitudinal direction of each thread (in the direction of arrow A in FIG. 2). Is in contact with As described above, the surfaces of the reinforcing thread 16 and the X-ray contrast thread 18 are uneven, and the X-ray contrast thread 18 in the direction of arrow A in FIG. 2 (that is, the direction in which the X-ray contrast thread 18 falls out of the gauze). Further, the frictional resistance of the surface in contact with the reinforcing yarn 16 is further increased, and the X-ray contrast yarn 18 is securely held by the reinforcing yarn 16 without falling off the gauze 10. Further, the reinforcing yarn 16 and the X-ray contrast yarn 18 prevent the X-ray contrast yarn 18 from coming off from the medical gauze 10 due to the frictional resistance of the surface with a large number of wefts 15 that cross alternately up and down at a plurality of locations. Is done.

  Moreover, the gauze 10 for medical use of this invention can utilize the conventionally well-known manufacturing method of gauze. In the embodiment, two of the warp yarns 14 of the medical gauze 10 are replaced with the reinforcing yarn 16 and the X-ray contrast yarn 18. Therefore, it is possible to manufacture very easily without requiring a complicated process. Note that the medical gauze of the present invention is not limited to the above-described embodiment, and the X-ray contrast yarn and the reinforcing yarn are configured to be parallel to the weft, or the X-ray contrast yarn is used for medical purposes. A plurality of pieces may be woven into the gauze, and a part of the configuration can be changed as appropriate without departing from the spirit of the present invention.
