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 yarn (yarn) 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, X-ray contrast yarns are woven into each of the longitudinal direction and the weft direction so that it can be easily reflected in the camera during X-ray photography, so that the gauze that remains in the body can be found more reliably. Ingenuity is made to make it easier.

  Further, since the X-ray contrast yarn is made of synthetic resin fiber or the like, there is a problem that the X-ray contrast yarn tends to fall 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 in which the X-ray contrast yarn is less likely to fall off from the gauze body and more easily finds the gauze that remains in the body more reliably.

  The present invention has been made in view of the above points, and proposes a medical gauze in which the X-ray contrast yarn is not easily detached from the gauze body with a simple configuration, and the X-ray contrast yarn is easily reflected in the X-ray photograph. is there.

  In other words, the invention of claim 1 is a medical gauze in which an X-ray contrast yarn is integrally knitted on a gauze body formed by alternately intersecting warps and wefts, and a plurality of X-rays in the warp direction of the gauze body. The present invention relates to a medical gauze characterized in that a transcontrast part made of a line contrast thread is formed and a weft contrast part made of a plurality of X-ray contrast threads is also formed in the weft direction of the gauze body.

  The invention of claim 2 relates to the medical gauze according to claim 1, wherein each of the transcontrast part and the weft contrast part is composed of two X-ray contrast threads.

  The invention of claim 3 relates to the medical gauze according to claim 1 or 2, wherein the X-ray contrast yarn is a yarn impregnated with a contrast agent.

  The invention of claim 4 relates to the medical gauze according to claim 1 or 2, wherein the X-ray contrast yarn is a metal wire.

  A medical gauze according to the invention of claim 1 is a medical gauze in which an X-ray contrast yarn is integrally knitted on a gauze body composed of alternating intersections of warps and wefts, and a plurality of gauze bodies in the warp direction of the gauze body. A trans-contrast part made of a single X-ray contrast yarn is formed, and a weft contrast part made of a plurality of X-ray contrast yarns is also formed in the weft direction of the gauze body. It is possible to provide a medical gauze that does not easily drop the contrast yarn. In addition, since the X-ray contrast yarn can be woven with the entangled structure using existing equipment, weaving of the medical gauze is easy and economical.

  The medical gauze according to the invention of claim 2 is economical in that the transcontrast part and the weft contrast part are each composed of two X-ray contrast yarns in claim 1, and the X-ray contrast medium is economical and simple. The thread can be made difficult to fall off the gauze body.

  The invention of claim 3 is that in claim 1 or 2, since the X-ray contrast yarn is a yarn impregnated with a contrast agent, it is easy to weave a medical gauze.

  The bill of claim 4 is easily reflected in an X-ray photograph in claim 1 or 2 because the X-ray contrast yarn is a metal wire.

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 an intersection part vicinity. 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 yarns 23 constituting the warp contrast portion 21 and the weft contrast portion 22 cross in the warp direction of the gauze body 11 and are woven together with the warp yarns 14 and the weft yarns 15. The X-ray contrast yarn 23 is woven together with the warp yarn 14 and the weft yarn 15. As the X-ray contrast yarn 23, a conventionally known one is used. For example, an X-ray contrast yarn in which barium sulfate is added to a synthetic resin fiber such as polypropylene resin, polyester resin, polyethylene resin, polyvinyl chloride resin, or metal wire Etc.

  A medical gauze 10 shown in FIG. 1 has a transcontrast unit 21 and a transcontrast unit 22 each made up of a plurality of X-ray contrast threads 23 in the longitudinal and weft directions. Consists of two X-ray contrast threads 23. When the medical gauze 10 remains in the body, when X-ray imaging is performed, the transcontrast unit 21 and the wetting unit 22 are arranged in a cross shape. Even when it is difficult to reflect, the latitude imaging unit 22 is reflected in the X-ray photograph, and the medical gauze 10 in the body can be safely found. Since the transcontrast part 21 and the latitude contrast part 22 are arranged in a cross shape, at least one of them is reflected in the X-ray photograph, and the discovery rate of the remaining gauze is remarkably improved. Further, since two X-ray contrast yarns 23 are woven in each of the warp direction and the weft direction, the line reflected in the X-ray photograph becomes thick and easy to visually recognize, which is economical.

  As shown in the enlarged view showing the outline of the vicinity of the intersection 30 where the transillumination unit 21 and the wetting contrast unit 22 cross, the two adjacent X-ray contrast yarns 23 of the transcontrast unit 21 include the warp 14 and Since the weft 15 is plain woven together, the weft 15 is woven alternately. Then, at the intersection 30 where the transcontrast part 21 and the latitude contrast part 22 cross each other, the respective contrast yarns are plain woven. Since the same material is easier to fit when different materials are in contact with each other and the frictional force is increased, the X-ray contrast yarn 23 is woven alternately, and the friction is increased. 11 is more difficult to drop off.

  In the embodiment, the weft yarn 15 is knitted by an air jet loom. The air jet loom ejects compressed air from a weft insertion nozzle to inject the weft, the weft flies between shafts, and the tip is drawn into a suction pipe on the opposite side of the nozzle to perform weft insertion. In the air jet loom, since the weft is passed through only one direction, the weft is cut every time one stage is passed. Therefore, when weaving the X-ray contrast yarn as a weft, the contrast yarn nozzle is moved to the weft ejection position by a known means at a predetermined interval or position in the weaving process of the gauze body, and the X-ray contrast yarn And then knitting.

  Thereby, the X-ray contrast yarn can be woven very easily in the weft direction of the medical gauze, and the X-ray contrast yarn can be produced without causing surplus yarn due to folding at the side edge of the original fabric. It is extremely efficient and the number and position of the X-ray contrast threads can be set freely. In the case where a plurality of X-ray contrast threads are arranged in the weft direction, it is only necessary to change the interval for moving the contrast thread nozzles.

  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. Further, the formation of the densely woven part 51 in which the wefts 15 are densely arranged at both ends of the thick step part 19 and the middle ear entangled woven part in which the wefts 15 are entangled with each other makes the gauze after cutting difficult 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.

  Each of the contrast enhancement section 21 and the latitude contrast section 22 can use known dropout prevention means. For example, the warp and the weft on both sides of each of the contrast portions 21 and 22 are made dense, or the X-ray contrast yarn 23 is further twisted together with the above-described synthetic resin fibers and other thread members to further increase the friction resistance. May be raised.

  In the medical gauze 10, a transcontrast portion 21 and a weft contrast portion 22 each including a plurality of X-ray contrast yarns 23 are formed on a gauze body 11 including the warp 14 and the weft 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.
