Description

  The present invention relates to a medical gauze, and more particularly to a medical gauze in which an X-ray contrast yarn arranged in the weft direction of a gauze body is difficult to fall off.

  Medical gauze is used in large quantities, for example, by absorbing blood or the like when performing surgery, or by being sandwiched between a scissor and tissue to prevent tissue damage when pulling the tissue with a scissors. In order to prevent gauze from being left in the body after surgery, precautions have been taken, such as counting used gauze to prevent mistakes.

  In addition, in the event that the gauze is left in the body, a medical gauze in which an X-ray contrast member (thread) is knitted into the gauze body is used. As a result, gauze remaining in the body can be found by radiography after surgery.

  In this type of conventional medical gauze, an X-ray contrast member is woven in the warp direction of the gauze body. This is knitted using a shuttle (杼) when passing the weft yarn of the gauze body, and the weft yarn is formed by a single long yarn that is folded back at the end. This is because it is complicated or difficult to knitting an X-ray contrast member having a certain length. In the warp direction, by using a part of the warp arranged in the beam as an X-ray contrast member, a medical gauze in which the X-ray contrast member is woven can be easily and continuously knitted. .

  Since the X-ray contrast yarn is made of synthetic resin fiber, there is a problem that the X-ray contrast yarn tends to come off from the gauze body made of cotton yarn. For this reason, there has been proposed a medical gauze that is densely plain-woven on one side of the X-ray contrast yarn to make it difficult for the X-ray contrast yarn to fall out (see Patent Document 1). Thus, there has been a demand for a medical gauze that is easy to handle because it is difficult for the X-ray contrast yarn to fall off the gauze body.

1 is a schematic plan view of a medical gauze according to an embodiment of the present invention. It is an enlarged plan view which shows the outline of a entanglement structure. It is a schematic plan view which shows the original fabric of the medical gauze of this invention.

  As shown in FIG. 1, the medical gauze 10 has a plain weave gauze body 11 in which warp yarns 14 and weft yarns 15 alternately intersect. The thickness of the warp yarn 14 and the weft yarn 15 and the size of the gauze body 11 are not particularly limited. However, in the embodiment, the warp yarn 14 and the weft yarn 15 are made of cotton yarn, both 40th (length per unit weight of about 453.5 g) Is a plain weave with a density of about 12 pieces / cm, and the size of the gauze body 11 is about 30 cm × 30 cm. The medical gauze 10 of the embodiment is manufactured by cutting a large-size original fabric F, as will be described later, and a middle ear portion 17 is formed on the side end portion 16 in the direction of the weft 15. A thick step portion 19 is formed at the end portion 18 in the warp yarn 14 direction.

  The X-ray contrast yarn 20 is provided in the warp direction of the gauze body 11. That is, at least one warp forming the gauze body is an X-ray contrast yarn. The X-ray contrast yarn 20 is woven together with the warp yarn 14 and the weft yarn 15. As the X-ray contrast yarn 20, a conventionally known one is used. For example, an X-ray contrast yarn in which barium sulfate is added to synthetic resin fibers such as polypropylene resin, polyester resin, polyethylene resin, and polyvinyl chloride resin, or a metal wire Etc.

  The medical gauze 10 shown in FIG. 1 has one X-ray contrast yarn 20 woven in the warp direction. When the medical gauze 10 remains in the body, when X-ray imaging is performed, the X-ray contrast yarn 20 is reflected in the X-ray photograph, and the medical gauze 10 in the body is more easily found.

  As shown in the enlarged view showing the outline of the entanglement structure 40 in FIGS. 2 (a) and 2 (b), the X-ray contrast yarn 20 is woven with one adjacent warp 14 (auxiliary yarn 30) and weft 15. As a result, the entangled structure 40 is provided. Tangle weave refers to a weaving method in which warps are entangled. In the case of a normal woven fabric, the warp and the weft are perpendicular to each other and the warps are parallel (so-called plain weave). Become. The entanglement structure 40 according to the medical gauze 10 of the present invention has an entanglement structure 40A called “紗” as shown in FIG. 2 (a) and an entanglement called “よ う な” as shown in FIG. 2 (b). Structure 40B is used.

  The entangled structure 40A in FIG. 2A is woven by twisting and twisting two adjacent warps (in the present invention, the X-ray contrast yarn 20 and the auxiliary yarn 30) for each weft 15. That is, as described in claim 2, one weft 15 penetrates through the entangled portion 41 where the X-ray contrast yarn 20 and the auxiliary yarn 30 are entangled, and this one set is continuously entangled structure 40A (紗). This entanglement structure 40A is easy to weave.

  The entangled structure 40B in FIG. 2 (b) is woven by repeating an odd-numbered (three, five, etc.) plain weave, then entwining the X-ray contrast yarn 20 and the auxiliary yarn 30. That is, as described in claim 3, a plurality of wefts 15 penetrate through the entangled portion 41 where the X-ray contrast yarn 20 and the auxiliary yarn 30 are entangled. In particular, when the weft 15 is woven in the tangled portion 41 using the X-ray contrast yarn 20 and the auxiliary yarn 30 as warps, the X-ray contrast yarn 20 is difficult to fall off. This entangled structure 40B is an entangled structure called a soot and is easy to weave.

  These entanglement structures 40 may be used when forming a middle ear entanglement weave disposed on the outer edge of the middle ear 17 portion such as gauze. Adjacent warp yarns 14 form an entangled structure by planetary gears incorporated in the loom, and the outer edge of the middle ear 17 portion is entangled to form a middle ear entangled weave portion. The entanglement structure 40 of the present invention can interweave the X-ray contrast yarn 20 and the auxiliary yarn 30 using a planetary gear used for weaving the middle ear entanglement weave. Thereby, it is possible to weave the medical gauze 10 in which the X-ray contrast yarn 20 is not easily dropped from the gauze body 11 with existing equipment. Since existing equipment can be used, it can be easily woven and is economical.

  As shown in FIG. 3, in the raw fabric F of the medical gauze 10, by forming a thick step portion 19 in which the weft 15 is rough in the warp direction, the thick step portion 19 is cut to form a plurality of medical gauze 10. Can be produced. In addition, as in the case of the densely woven portion 51 in which the wefts 15 are densely arranged at both ends of the thick step portion 19 and the entangled weave of the X-ray contrast yarn 20 and the reinforcing yarn 30, the middle entangled woven portion in which the wefts 15 are entangled is formed. Thus, the gauze after cutting is less likely to fray.

  Further, when a plurality of sheets are produced in the transverse direction using a wide loom, a large amount of the middle ear 17 having a coarse warp 14 is formed at predetermined intervals, and the middle ear 17 is cut to produce a large amount at a time. The medical gauze 10 can be manufactured economically. In the embodiment, 30 × 30 cm was produced by arranging the equivalent of 5 sheets in the weft direction. At both ends of the middle ear portion 17, the warp yarns 14 are densely formed to form the densely woven portion 52 so that fraying hardly occurs.

  In this medical gauze 10, an X-ray contrast member 20 is integrally disposed on a gauze body 11 composed of warps 14 and wefts 15. Therefore, it is possible to manufacture very easily without requiring a complicated process and equipment. The medical gauze of the present invention is not limited only to the above-described embodiment, and may be smaller than 30 × 30 cm, and the yarn count is more adjusted to adjust water absorption and flexibility. In the range which does not deviate from the meaning of this invention, such as using a thick thing or a thin thing, a part of composition can be changed suitably and can be carried out. ,
