DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved stool collection tool which collects a certain amount of stool and can work comfortably in measurements such as fecal occult blood test.

[0002]

2. Description of the Related Art Fecal occult blood tests are often performed in colorectal cancer screening and the like. In performing a fecal occult blood test, it is necessary to collect feces as a specimen without excess or deficiency. As a collection tool used for collecting feces, a stick made of a hygroscopic material is pierced into the feces several times, and the excess feces that have adhered are wiped with paper, etc., and a tool for collecting the required amount (Japanese Utility Model No. 1-158964) A tool (Publication No. 2-140468) for piercing a feces with a groove or hook at the tip and wiping excess feces with a rubber O-ring is known.

[0003] Further, in handling fecal occult blood, when handling a specimen, the fecal sampling rod is transferred to another container having a dropper function containing an extract, and a tool used for the test (actually used in a test).
No. 1-158964) and the stool collection rod is kept in the buffer solution without being transferred to another container, and the container tip is opened by cutting, piercing, removing the cap, etc. 140468
No.) are known.

[0004]

The conventional stool collection device is
Work that was extremely uncomfortable for the collector, such as wiping the stool attached to the stool collection rod with paper, was required. In addition, there is a problem that the amount collected differs depending on the viscosity of the feces.

[0005] In the form having a buffer solution in a container,
Since a liquid leak easily occurs, a plurality of O-rings are used, or a soft material that is easily deformed and difficult to handle is used, and has a complicated structure and is expensive.

[0006] Further, in performing a fecal occult blood test or the like, the fecal sampling stick to which feces are attached is taken out of the extraction solution container, transferred to another container containing a buffer solution, and further, the sample solution is taken out. Therefore, there is a risk that the operator may touch the stool solution when cutting the tip of the container, piercing, removing the cap, etc.If the solution scatters as fine droplets, In addition, there was a problem of polluting the surroundings.

[0007]

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

Further, by installing a dropper having a hollow needle so as to be able to pierce the extraction solution holding container at the same time as mounting the extraction solution holding container at the tip, it is possible to perform a fecal occult blood test without worrying about contamination. And found that the stool collection device of the present invention was completed.

That is, the present invention relates to a feces collection rod (hereinafter, referred to as a collection rod) made of a fiber bundle having water absorbency, and a feces collection rod support member (hereinafter, referred to as a collection rod support member).
A stool collection 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), wherein the scraper is engaged with an inner wall of the container and a lower portion of a collection rod support member, and further collected. This is a stool collection tool whose tip is sharp. Further, the present invention is a feces collecting tool which may be provided with a dropper having a hollow needle for piercing a thin portion of a container, and which may have a filter in either the container or the dropper.

The stool collection tool of the present invention comprises a collection rod made of a water-absorbing fiber bundle, a collection rod support member serving as a handle for the collection rod, a scraper, 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-absorbing fiber bundle,
Except for the tip, it is coated with a heat-shrinkable resin to prevent liquid leakage from the side of the sampling rod. For this reason, when stabbed in feces, feces penetrate between fibers, and the surface may be smooth. Therefore, it is more suitable for collecting a certain amount of feces regardless of the viscosity of the feces, as compared with a case in which grooves and notches are provided to scrape feces. Further, the tip is a sharp cone, which is shaped so that excess feces are completely removed by the scraper.

The collection rod support member serves as a handle for the collection rod,
Usually, it is used with the support member attached. Further, the support member is configured so as to seal and hold excess feces adhered to the sampling rod by engaging with the scraper.

On the one hand, the scraper wipes excess feces adhering to the collection rod, engages with the collection rod support member and keeps it tightly closed, and on the other hand seals the container to prevent liquid leakage from the container.

The scraper has in the center a hole of a smaller diameter than the collecting rod and a membrane blocking this hole, which film is broken by the collecting rod and a hole penetrates from one end of the scraper to the other end. . Excess feces must not come into contact with the sample solution even if the holes penetrate. 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 broken by inserting the sampling rod adheres to the sampling rod, and maintains the same sealing as when the thin film is present.

Materials usable as the scraper include, for example, thermal plastic elastomer, rubber, various soft plastics, urethane rubber, polyurethane and the like.

[0017] Since the scraper is soft, it is significantly deformed by receiving an external force, and if it is used as it is for a feces collection tool, the operability is reduced at first. Therefore, in the present invention, operability is improved by using a hard scraper holding member.

In the present invention, the container, the scraper holding member, and the sampling rod supporting member use relatively hard materials. In order to combine members made of hard materials and try to occlude without leaking liquid, it is necessary to increase the accuracy of each member and tighten the occlusion, which not only reduces operability but also reduces the sample solution. It scatters and causes pollution.

Therefore, by combining a soft scraper with the above-mentioned relatively hard member, the use of a relatively low-precision member achieves both prevention of liquid leakage and improvement of operability.

The container is a cylindrical container having a thin end. The thin part has a thickness of 0.1 mm to 0.5 mm and can be easily penetrated by a 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. A hollow needle penetrates the thin film at the tip of the container at the same time as the mounting,
The stool collection tool can be used as a dropper without touching the sample solution.

At this time, it goes without saying that the material of the container can be appropriately selected so that the side wall of the container can be pressed with a finger and the sample solution can be dropped.

As a material that can be used as a material for the container, polyethylene, polypropylene, polyvinyl acetate and the like can be used.

A filter may be provided in either the container or the dropper for use. Also, it goes without saying that a solution can be taken out by inserting a commercially available chip after penetrating the hole instead of the dropper.

[0025] 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 having the extraction solution are easily cut. Needless to say, the specification of the dropper or chip is possible.

By integrally forming the container and the scraper holding member, it is possible to prevent a user from erroneously using the container such as directly filling the container with feces. Also, since the number of parts can be reduced, the number of working steps can be reduced, and the manufacturing cost can be reduced.
