Description

  The present invention relates to a stool collection sheet used when collecting stool in a flush toilet.

Medical examinations in medical examinations are widely used in medical examinations such as medical checkups, medical checkups, and health management of employees in food factories, for the purpose of examining colorectal cancer, the presence of parasites, and the presence of intestinal bleeding. Yes.
Such stool collection for inspection is performed from the stool excreted in the toilet using a stool collection tool.

In recent years, toilet bowls have been flushed, and most of the toilet bowls have been made into Western style toilets. In these Western style flush toilets, the area of the puddle is widened, so the excreted feces sink into the puddle. It is difficult to collect feces.
For this reason, a stool collection sheet that can temporarily receive and hold the discharged stool and can be washed away with the stool after collection is used.

As the stool collection sheet, a sheet obtained by treating one or both surfaces of a water-soluble paper sheet with a water-resistant treatment agent such as a water-resistant printing ink or a water-resistant resin coating agent is known. (Patent Document 1)
In the case of such a single sheet, if there is a lot of stool, it may not be able to fully support this. First, a toilet paper folded in two or three layers is laid on the surface of the puddle, and then the stool The collection sheets are spread and spread, but because of the high water absorption of the toilet paper itself, it often sinks and cannot hold the feces sufficiently.

Also known is a stool collection sheet in which water-dispersible paper is laminated on both sides of a water-soluble film of polyvinyl alcohol obtained by partially saponifying polyvinyl acetate to form a three-layered paper and the outer periphery of the paper is adhered. . (Patent Document 2)
This is intended to keep the air between the film and paper and to increase the retention of stool on the surface of the water pool by its buoyancy, but it is folded small before use, It can also be seen that the air cannot be sufficiently retained by simply expanding it.

  In the present invention, the stool for stool examination can be collected by reliably holding the excreted stool by laying it on the puddle of the flush toilet, and after the collection, it is washed away with the stool. It is intended to obtain a stool collection sheet that can be used.

  Since such a stool collection sheet needs to be washed away after use, a water-soluble adhesive was used even when an adhesive was used. However, as a result of various studies by the present inventor, even if it is a water-insoluble adhesive, when the amount of use is small, the flush toilet is not clogged, and it is easily dispersed and cleaned with the stool. The present inventors have found that it can be washed away and have completed the present invention.

  The present invention has two paper sheets having water dispersibility and water resistance that can cover the water surface of a flush toilet. Between the two paper sheets, water-insoluble By adhering the adhesive in the form of dots and disposing the dot-shaped adhesive portions so as to be dispersed throughout the sheet, the two paper sheets are integrated into a stool collection sheet. .

  The stool collection sheet of the present invention is usually provided by being folded. However, when the sheet is expanded, air is introduced between the two overlapping paper sheets from the outer peripheral edge to form an air layer. So, if you lay it so as to cover the water surface of the flush toilet, the paper sheet is water-resistant, and the stool collection sheet floats on the water surface due to the air layer between the paper sheets Therefore, even if stool is received by this sheet, it does not sink easily. Also, when the stool is received by this collection sheet, the paper sheet is wet with the water in the water reservoir, but the adhesive used in this collection sheet is water-insoluble, so the two paper sheets may be peeled off immediately. Therefore, it is possible to keep the collection sheet integrated and securely hold the stool.

  After collecting the stool sample from the stool held by the stool collection sheet, this stool collection sheet is also flowed together with the stool, but the adhesive that integrates these two paper sheets is dot-shaped, Moreover, since it is provided in a dispersed state, the adhesive hardly inhibits the water dispersibility of the paper sheet, and it flows cleanly without causing troubles such as clogging the flush toilet. be able to.

It is a perspective view which shows the Example of this invention. It is an AA line expanded partial sectional view of what is shown in FIG. It is explanatory drawing which shows the use condition of what is shown in FIG. It is a top view which shows the other Example of this invention. It is a top view which shows other Example of this invention. It is a top view which shows the other example of this invention.

The paper sheets 10 and 20 of the stool collection sheet 1 of the present invention have water dispersibility so as not to clog the toilet when flushed away from the flush toilet. At the same time, the water surface of the reservoir of the flush toilet is used. It also has water resistance so that when it is covered, it absorbs water immediately and does not sink into a puddle.
As such paper sheets 10 and 20, known ones can be used, and a water-resistant agent such as ink or resin is applied to one side or both sides of paper having excellent water dispersibility, or paper is used. A paper sheet or the like obtained by adding a water-resistant agent during papermaking can be suitably used. Giving water resistance to the paper sheet generally acts in the direction of hindering the water dispersibility, so that the water dispersibility as the paper of the stool collection sheet 1 described above is moderately waterproofed. To.

The paper sheets are stacked in two, and are integrated by interposing an adhesive 30 between the paper sheets 10 and 20. As such an adhesive 30, a water-insoluble adhesive 30 is used. .
The water-insoluble adhesive 30 may be a stool collected from a natural product such as paraffin or casein, a rubber material, or a resin material that can integrate the paper sheets 10 and 20. However, since this paper sheet is likely to be washed away by water, it is not required to have very strong adhesiveness, and paraffin is an adhesive in the present invention. One of the preferred agents 30 is.

Such an adhesive 30 is formed into small dots and arranged in a dispersed state on the entire paper sheets 10 and 20. In the case of a circle, the size of the dot is preferably 20 mm or less, and when the adhesive 30 has a large adhesive action, the dot can be a small dot.
In this way, both the paper sheets 10 and 20 are integrated by the adhesive 30 dispersed and arranged in the form of dots, and the stool collection sheet 1 is obtained.

  The stool collection sheet 1 shown in FIG. 1 has four paraffin dots having a diameter of 20 mm on a paper sheet 20 formed in a square shape with a side of 30 cm, and four corners thereof and spaces between them. Eight pieces are dispersedly arranged so as to be positioned, and another paper sheet 10 is stacked thereon and bonded and integrated. This can be integrated by placing the paraffin dissolved by heating on one paper sheet in the form of dots in a dispersed manner, and stacking the other paper sheet on the paper sheet and press-bonding them.

Such a stool collection sheet 1 is usually provided for two days of collection, two small folds together with two collection tools, and two collections in a plastic bag.
When using this, when the stool collection sheet 1 taken out from the plastic bag is expanded, the two paper sheets 10 and 20 are only partially bonded in a dispersed state. Thus, air can easily flow in between the two paper sheets from the outer peripheral edge of the sheet, thereby forming an air layer 40 between the paper sheets 10 and 20 (see FIGS. 1 and 2).

  When the stool collection sheet 1 thus formed with the air layer 40 is laid so as to be placed on the water reservoir surface 71 of the western flush toilet 70 as shown in FIG. 3, the paper sheet absorbs water appropriately due to its waterproofness. The part that is in contact with the water reservoir surface 71 while being blocked and that is not in contact with the water reservoir surface 71 follows the inner wall 72 of the western flush toilet 70 with the outer peripheral edge facing upward. And in the part which contacted the water reservoir surface 71, the paper sheet in contact with water absorbs water and contracts, while the paper sheet in contact with water partially absorbs water and contracts slightly. Since the air layer 40 is hardly contracted, the air layer 40 can be sufficiently retained.

  When stool is excreted on the stool collection sheet 1, the excreted stool is firmly received by the stool collection sheet 1, and the adhesive 30 that integrates both paper sheets 10 and 20 is water-insoluble. Therefore, the two paper sheets 10 and 20 are not easily separated and the outer peripheral edge is along the inner wall of the toilet, so that the water layer does not enter between the two sheets, and the air layer 40 is maintained, so that the state of floating in the water reservoir can be maintained with the stool placed thereon, so that the stool for stool examination can be reliably collected from the stool thus held using a sampling device. it can.

When the stool collection is completed, the stool collection sheet 1 is allowed to flow together with the stool. However, even if there is an air layer 40 between the paper sheets 10 and 20, it does not interfere with the flow. , 20 is water-insoluble, but is only partially adhered in a dot shape, so that the water dispersibility of the paper sheet of the stool collection sheet 1 may be hindered. Absent.
In the case of using paraffin, buoyancy is generated in the adhesive part because it is lighter than water, and there is a tendency to sink in the other part. It is easy to tear and can be smoothly washed away from the toilet.

  The size of the adhesive 30 may be substantially the same as shown in FIG. 1, but may be different from each other. In FIG. 4, the size of the inner adhesive 32 is smaller than that of the outer adhesive 31, so that the air layer 40 is made larger while maintaining the integrity between the paper sheets. It can be formed, facilitating the retention of feces, and since there are few adhesion parts, it can be made difficult to clog when flushing away.

  The arrangement of the adhesive 30 can be an appropriate arrangement as long as the two paper sheets are integrated and the air layer 40 is formed, and may be irregular. In this case, as shown in FIG. 5, the adhesive 33 is arranged at the four corners, and the adhesive 34 is arranged so as to form a small square rotated 45 degrees inside thereof, or as shown in FIG. The dot-shaped adhesives 35 can be arranged in a staggered arrangement so that the number of dispersed adhesives 35 can be increased. When arranged in this way, the adhesive when one of the stool drops and the other adhesive pulls with the other adhesive, and the paper sheets 10 and 20 tend to have a mesh-like wrinkle. Even if the amount of water in the stool is large, the stool can be prevented from spreading over the entire paper sheet.

  The shape of the stool collection sheet 1 of the present invention can be an appropriate shape that matches the shape of the toilet, such as a rectangle, an ellipse, and a circle, in addition to the square shape described above. In addition to the circular shape shown in the figure, a triangular shape, a polygonal shape, or other shapes may be used. The stool collection sheet 1 can also be used in a Japanese style flush toilet.
