DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
It was extremely uncomfortable for the collector to wipe the stool attached to the stool collection stick with paper. In addition, there was a problem that the amount collected was different depending on the viscosity of feces.

Further, the one having a buffer solution in the container is
Since liquid leakage is likely to occur, a plurality of O-rings are used, or a soft material that is easily deformed and difficult to handle is used, so that it has a complicated structure and is expensive.

Further, in conducting a fecal occult blood test or the like, the feces sampling rod with the feces attached is taken out from the extraction solution container and transferred to another container containing the buffer solution, and then the sample solution is taken out. Therefore, there is a risk that the worker may touch the solution of feces because the tip of the container is cut, pierced, the cap is removed, etc. Not only that, but there was a problem of polluting the surroundings.

[0007]

As a result of various investigations to solve the above problems, the present inventors have found that a scraper made of a soft material and a scraper holding member made of a relatively hard material for holding the scraper are used. It was found that feces can be collected without using unpleasant work by using the member, and the present invention has been completed.

Further, by mounting a dropper having a hollow needle at the tip of the container for holding the extraction solution at the same time as mounting it on the tip of the container, a fecal occult blood test can be carried out without worrying about contamination. They have also found out that they have completed the fecal collection tool of the present invention.

That is, according to the present invention, a stool collection rod (hereinafter referred to as a collection rod) made of a fiber bundle having water absorbability, a stool collection rod support member (hereinafter referred to as a collection rod support member),
A fecal sampling tool comprising a scraper having a soft thin film, a scraper holding member, and an extraction solution holding container (hereinafter referred to as a container), in which the scraper engages with the inner wall of the container and the lower part of the collecting rod support member, and is further collected. It is a fecal sampling tool with a sharp tip on the rod. Further, the present invention is a fecal collection tool that may be equipped with a dropper having a hollow needle for breaking through a thin portion of the container, and may have a filter in either the container or the dropper.

The feces collecting tool of the present invention comprises a collecting rod made of a water-absorbent fiber bundle, a collecting rod supporting member serving as a handle of the collecting rod, a scraper and a scraper holding member, a container and a dropper having a hollow needle. It consists of six members.

The sampling rod is made of a water-absorbent fiber bundle,
In order to prevent leakage from the side of the sampling rod, the tip is coated with heat-shrinkable resin except for the tip. Therefore, when the stool is pierced, the stool penetrates between the fibers, so the surface may be smooth. Therefore, it is suitable for collecting a fixed amount of stool regardless of the viscosity of the stool, as compared with a device that scrapes the stool by providing a groove or a notch. Furthermore, the tip is a cone with an acute angle, and the surplus feces are completely removed by the scraper.

The sampling rod support member serves as a handle for the sampling rod,
Usually, it is used with the support member attached. Further, the support member is in a form of engaging with the scraper and sealingly holding the excess feces adhering to the sampling rod.

On the one hand, the scraper wipes off the excess feces adhering to the collecting rod, and bites the collecting rod supporting member so as to keep it hermetically sealed. On the other hand, the scraper seals the container to prevent liquid leakage from the container.

The scraper has a hole having a diameter smaller than that of the sampling rod in the central portion, and a thin film that shields this hole, and the thin film is ruptured by the sampling rod, and the hole penetrates from one end of the scraper to the other end. . Even if the hole penetrates, the sample solution should not come into contact with excess feces. This is because a certain amount of feces must always be dissolved in the sample solution.

Therefore, in the scraper used in the present invention, the thin film portion, which is broken by inserting the sampling rod, adheres closely to the sampling rod, and maintains the same sealing as when there was a thin film.

As the material which can be used as the scraper, for example, thermal plastic elastomer, rubber, various soft plastics, urethane rubber, polyurethane and the like can be used.

Since the scraper is soft, it deforms remarkably when subjected to an external force, and if it is used as it is in a feces collecting tool, the operability is deteriorated at first. Therefore, in the present invention, the operability is improved by using the hard scraper holding member.

In the present invention, the container, scraper holding member and sampling rod support member are made of relatively hard materials. When combining members made of hard materials and trying to occlude without leaking liquid, it is necessary to increase the accuracy of each member and tighten the occlusion, which not only reduces the operability, but the sample solution It will also scatter and cause pollution.

Therefore, by combining a soft scraper and the above-mentioned relatively hard member, it is possible to achieve both prevention of liquid leakage and improvement of operability by using a member with relatively low accuracy.

The container is a cylindrical container having a thin tip. The thin portion has a thickness of 0.1 mm to 0.5 mm and can be easily penetrated by the hollow needle attached to the dropper.

The dropper has a hollow needle inside and is used by being attached to the tip of the container as required for inspection or the like. At the same time as mounting, a hollow needle penetrates the thin film part at the tip of the container,
The feces collecting tool can be used as a dropper without touching the sample solution.

At this time, needless to say, the material of the container can be appropriately selected so that the side wall of the container is pressed with a finger and the sample solution can be dropped.

Polyethylene, polypropylene, polyvinyl acetate and the like can be used as the material of the container.

A filter may be provided on either one of the container and the dropper for use. Needless to say, instead of the dropper, it is possible to insert a commercially available chip after the hole is penetrated to take out the solution.

The container may be formed integrally with the scraper holding member. In this case, a groove may be provided in the cylindrical portion of the integrally formed container and the scraper holding member so that the upper portion holding the scraper and the lower portion holding the extraction solution can be easily cut. Also, it goes without saying that the specifications of the dropper or chip are possible.

By integrally forming the container and the scraper holding member, it is possible to prevent the user from mistakenly using the method such as directly packing feces into the container. Further, since the number of parts can be reduced, the working process can be reduced and the manufacturing cost can be reduced.
