JP4669296B2 - Disposable sanitary member and method for manufacturing the same - Google Patents

Description

  The present invention relates to a disposable sanitary member such as a cotton ball provided with an X-ray contrast yarn and a method for manufacturing the same.

  Conventionally, as this type of disposable sanitary member, X-ray contrast yarns are woven into weft yarns and woven into a gauze body having a plain structure in which cotton warps and wefts are alternately crossed and plain woven. The X-ray contrast yarn is attached by being twisted by the weaving yarn substantially parallel to the warp yarn of the gauze body.

In addition, the gauze body has a twisted tissue formed by interweaving the X-ray contrast yarn and the weaving yarn, so that the weaving yarn is entangled with the X-ray contrast yarn, so that the X-ray contrast yarn is difficult to fall off. (For example, refer to Patent Document 1).
JP 2002-143212 A

  However, when the sanitary member has warps, wefts, and woven yarns, the X-ray contrast yarns are attached to the gauze body with the woven yarns, so that the X-ray contrast yarns cannot be easily removed from the gauze body. When a web-like absorbent cotton is used as this type of disposable sanitary material, the X-ray contrast yarn cannot be entangled with the absorbent cotton with the woven yarn, and it is difficult to make it difficult to remove the X-ray contrast yarn.

  In addition, cotton balls and swabs for sanitary materials using this web-like absorbent cotton are often smaller than the above-mentioned gauze body, so the X-ray contrast yarn that can be attached to these cotton balls and swabs is short. Therefore, the X-ray contrast yarn is difficult to be seen in the post-surgical radiographs, and it is difficult to find these cotton balls and swabs.

  The present invention has been made in view of such points, and an object of the present invention is to provide a disposable sanitary member such as a cotton ball which is difficult to come off an X-ray contrast yarn and can be easily found by X-ray photography, and a method for manufacturing the same.

Two of them are arranged inside. In addition, the X-ray contrast yarn 3 is located in the vertical direction in a transverse section 14 formed by a transverse virtual line 13 orthogonal to the longitudinal virtual line 11 at the center of the longitudinal virtual line 11 of the absorbent cotton 2. Along the absorbent cotton 2, two are disposed along the absorbent cotton 2. Here, the horizontal imaginary line 13 is an imaginary line that bisects the absorbent cotton 2 along the vertical direction when viewed from above.

  The X-ray contrast yarn 3 arranged along the longitudinal section 12 and the X-ray contrast yarn 3 arranged along the transverse section 14 are respectively divided into the longitudinal section 12 and the transverse section. 14 are arranged in parallel with each other at positions spaced apart at equal intervals from an intersection line 15 as a center line intersecting with the vertical direction. Therefore, the X-ray contrast yarn 3 is composed of the distance between the two X-ray contrast yarns 3 disposed along the longitudinal section 12 and the two X-rays disposed along the transverse section 14. It arrange | positions so that the distance between the contrast threads 3 may become equal. Here, the line of intersection 15 is a straight line passing through the absorbent cotton 2 along the vertical direction of the absorbent cotton 2 from the center of the absorbent cotton 2 as viewed from above.

  In other words, two X-ray contrast yarns 3 are substantially parallel in each of the longitudinal section 12 and the transverse section 14 along the vertical direction and the vertical direction of the lateral direction in which the absorbent cotton 2 intersects perpendicularly with each other when viewed from above. It is passed through. Further, the X-ray contrast yarn 3 is passed along the vertical direction at a position spaced apart from the outer surface of the absorbent cotton 2 by a predetermined distance from the center thereof, and is sewn into the absorbent cotton 2.

  Further, the X-ray contrast yarn 3 is disposed along one of the upper and lower portions of the absorbent cotton 2, for example, a portion slightly inside the upper surface, along the longitudinal imaginary line 11 and the transverse imaginary line 13 of the absorbent cotton 2. They are arranged so as to intersect in a substantially cross shape when viewed from above. Here, the portion of the X-ray contrast yarn 3 that intersects the upper part of the absorbent cotton 2 in a cross shape is spaced at equal intervals along the vertical imaginary line 11 and the horizontal imaginary line 13 around the intersection line. It is provided over the position.

  Next, the manufacturing method of the disposable sanitary member of the first embodiment will be described with reference to FIGS.

  First, as shown in FIGS. 2 (a) to 2 (c), as shown in FIG. 2 (a) to FIG. 2 (c), from the lower part of the absorbent cotton 2 which is appropriately separated from the intersecting line 15 of the absorbent cotton 2 along the horizontal imaginary line 13 by this distance. The X-ray contrast yarn 3 is passed through the X-ray contrast yarn 3 linearly toward the upper portion of the absorbent cotton 2 along the transverse cross section 14 and the vertical direction of the absorbent cotton 2, and the tip of the X-ray contrast yarn 3 is moved outward from the upper portion of the absorbent cotton 2. Make it protrude.

  Thereafter, as step 2, as shown in FIGS. 3 (a) to 3 (c), the tip of the X-ray contrast yarn 3 protruding outward from the upper part of the absorbent cotton 2 is the upper part of the absorbent cotton 2. At the same time, the base end portion of the X-ray contrast yarn 3 passing along the transverse cross section 14 of the absorbent cotton 2 is separated from the proximal end portion of the absorbent cotton 2 by a predetermined distance appropriately across the longitudinal virtual line 11. From the symmetrical position, along the transverse cross section and the vertical direction of the absorbent cotton 2, the X-ray contrast yarn 3 is linearly passed toward the lower portion of the absorbent cotton 2, and the tip of the X-ray contrast yarn 3 is attached to the absorbent cotton 2. Project from the bottom to the outside.

  Next, as step 3, as shown in FIGS. 4 (a) to 4 (c), the tip of the X-ray contrast yarn 3 protruding outward from the lower part of the absorbent cotton 2 is moved vertically from the intersection of the absorbent cotton 2. From the lower part of the absorbent cotton 2 that is appropriately separated by a predetermined distance along the imaginary line 11, the X-ray contrast line 3 passes linearly toward the upper part of the absorbent cotton 2 along the longitudinal section 12 and the vertical direction of the absorbent cotton 2. The tip of the X-ray contrast yarn 3 is projected outward from the top of the absorbent cotton 2.

  Thereafter, as step 4, as shown in FIGS. 5 (a) to 5 (c), the tip of the X-ray contrast yarn 3 protruding outward from the upper part of the absorbent cotton 2 is the upper part of the absorbent cotton 2. At the same time, the proximal end portion of the X-ray contrast yarn 3 passed along the longitudinal cross section 12 of the absorbent cotton 2 is separated from the proximal end of the absorbent cotton 2 by a predetermined distance appropriately across the horizontal virtual line 13. From the symmetrical position, along the longitudinal section 12 and the vertical direction of the absorbent cotton 2, the X-ray contrast yarn 3 is linearly passed toward the lower portion of the absorbent cotton 2, and the tip of the X-ray contrast yarn 3 is passed through the absorbent cotton 2 The disposable cotton ball 1 that protrudes outward from the lower part of the X-ray and can be contrasted in an X-ray photograph is obtained.

  As described above, according to the first embodiment, the two X-ray contrast yarns 3 are arranged in the vertical direction along the longitudinal section 12 of the spherical absorbent cotton 2, and the absorbent cotton 2 Two X-ray contrast yarns 3 are arranged in the vertical direction along the transverse section 14. As a result, a total of four X-ray contrast yarns 3 exist in the absorbent cotton 2 along the vertical direction. When the X-ray contrast yarn 3 is X-rayed on the cotton ball 1 attached to the absorbent cotton 2 Furthermore, the X-ray contrast yarn 3 attached to the cotton ball 1 is easily imaged on the X-ray photograph. Therefore, the cotton ball 1 can be easily found in the X-ray photograph.

  Further, when a single continuous filamentous X-ray contrast yarn 3 is passed along the up and down direction of the absorbent cotton 2 over a total of four times, the X-ray contrast yarn 3 is located above the absorbent cotton 2 and the absorbent cotton 2 The crosses were made in a substantially cross shape along each of the vertical virtual line 11 and the horizontal virtual line 13. As a result, the X-ray contrast yarn 3 is entangled at the upper part of the absorbent cotton 2, so that the X-ray contrast yarn 3 is not easily removed from the absorbent cotton 2. Therefore, the cotton ball 1 can be easily photographed in an X-ray photograph and the X-ray contrast yarn 3 is difficult to come off.

  Further, after passing the X-ray contrast yarn 3 from the lower part of the absorbent cotton 2 along the lateral imaginary line 13 from the intersection line 15 toward the upper part along the lateral cross section 14 of the absorbent cotton 2, From the upper part of the absorbent cotton 2 at a substantially symmetrical position across the longitudinal virtual line 11 along the transverse cross section 14 of the absorbent cotton 2 toward the lower part along the transverse cross section 14 of the absorbent cotton 2, Pass the tip. Furthermore, after passing the X-ray contrast yarn 3 from the lower part of the absorbent cotton 2 along the longitudinal imaginary line 11 from the intersection line 15 toward the upper part along the longitudinal cross section 12 of the absorbent cotton 2, The X-ray contrast yarn 3 from the upper part of the absorbent cotton 2 at a substantially symmetrical position across the horizontal imaginary line 13 along the longitudinal section 12 of the absorbent cotton 2 toward the lower part along the longitudinal section 12 of the absorbent cotton 2 It was set as the structure which let the front-end | tip part pass.

  As a result, a total of four X-ray contrast yarns 3 exist in the absorbent cotton 2 along the vertical direction, and the cotton ball 1 in which the X-ray contrast yarns 3 intersect in a substantially cruciform shape above the absorbent cotton 2 has a simple configuration. Therefore, it is possible to easily manufacture the disposable cotton ball 1 that is easy to find by X-ray imaging and is difficult to remove the X-ray contrast yarn 3.

  Further, by enlarging the substantially cross-shaped portion of the X-ray contrast yarn 3 positioned above the absorbent cotton 2, even when the cotton ball 1 is X-rayed from above, the X-ray contrast yarn of this cotton ball 3 becomes easy to be contrasted on the X-ray photograph. Therefore, no matter which direction the X-ray image of the cotton ball 1 is taken, the X-ray contrast yarn 3 of the cotton ball 1 can be easily imaged on the X-ray photograph. Therefore, the cotton ball 1 can be easily found in the X-ray image. You can be sure.

  In the first embodiment, the X-ray contrast yarn 3 is passed along the up-and-down direction of the absorbent cotton 2, but the longitudinal cross-section of the absorbent cotton 2 as in the second embodiment shown in FIG. Two X-ray contrast yarns 3 along either one of 12 or the transverse section 14 may be arranged so as to intersect in an X shape in a side view. Further, as in the third embodiment shown in FIG. 7, two X-ray contrast yarns 3 along the longitudinal section 12 of the absorbent cotton 2 and two along the lateral section 14 of the absorbent cotton 2. The X-ray contrast yarns 3 may be arranged so as to intersect with each other in an X shape in a side view.

  In addition, the X-ray contrast yarn 3 protrudes outward from the upper and lower portions of the absorbent cotton 2, but the portions protruding from the upper and lower portions of the absorbent cotton 2 of the X-ray contrast yarn 3 are some other things. The X-ray contrast yarn 3 may come off due to being caught on the surface of the absorbent cotton 2 without projecting the X-ray contrast yarn 3 to the outside at the upper and lower portions of the absorbent cotton 2. It is good to place it through.
