Such a conventional fecal sampling stick 100 is shown in FIG.
As shown in (A) to (C), the tip of the shaft 101 is pierced into the feces so that the feces 110 are attached to the notch 103, the recess 105, or the through hole 107 provided near the tip of the shaft 101. Samples are collected by scooping this out.

[0004]

By the way, in the examination of colorectal cancer and the like, it is desired to collect a sample from the surface portion of the feces that comes out by touching the intestinal wall. Further, in collecting, it is desired to secure specimens on the surface of various places of feces.

However, in the conventional stool collecting rod 100,
There is a problem that it is difficult to reliably collect a sample from the vicinity of the surface of feces, and once the notch 103 or the recess 105 is clogged with feces, a sample cannot be collected from another place.

Further, in the case of having the through hole 107, there is a problem that it is difficult to dissolve when immersed in the liquid in the container body.

Furthermore, in the conventional stool collection rod, depending on the hardness of the stool, it may not be possible to collect an appropriate amount of stool in the notch 103, the recess 105 or the through hole 107.

For this reason, the applicant of the present invention has previously filed Japanese Patent Application No. 7-2.
83260 (JP-A-9-126959),
We have proposed a stool collection stick with a stool collection brush on the tip of the shaft. A stool collection stick equipped with this stool collection brush can easily collect a sample from the vicinity of the surface by rubbing the surface of stool with a stool collection brush, and by scraping various parts of the stool, the sample can be collected from various parts. Can be collected.
In addition, there is no unevenness in the collected material due to the hardness of the stool, and the ease of dissolution when immersed in the liquid in the container is good, which is very excellent.

However, the stool collection brush system has a problem that the stool collection rod cannot be easily manufactured by injection molding or the like, resulting in high performance and high cost.

Therefore, in the present invention, similar to the stool collection brush method, the sample can be easily collected from the vicinity of the surface of the stool and the sample can be collected from various places of the stool. The purpose of the present invention is to provide a stool collection rod which is capable of surely collecting a sample regardless of the hardness of feces, is easily dissolved when immersed in a liquid, and is easy to manufacture. It is also intended to provide a stool collection container using such a stool collection rod.

The fecal sampling rod of the present invention is a fecal sampling rod for collecting feces as a specimen sample, wherein a coil-shaped projection is provided at the tip of the shaft portion, and the coil-shaped projection is provided in the coil-shaped projection. It is characterized in that it is configured to enter and hold feces. Here, the coil-shaped projection has a cavity that extends in the axial direction at the center, and is formed so as to have a gap of a predetermined width that allows feces to enter and exit from the side surface,
It has the same shape as the state in which no compression force is applied to the compression coil spring.

According to this stool collecting rod, the stool can be introduced into the internal cavity through the hole formed at the tip portion of the coil-shaped projection by piercing the stool with the tip of the shaft portion. At this time, since there is a gap on the side surface of the coil, air is not accumulated in the cavity and does not interfere, and the sample can be easily collected by piercing. Also, by piercing another part of the feces, it is possible to push in the first collected feces into the depth of the cavity while allowing some of the feces to escape from the gaps on the side surface, and to take new feces into the coiled protrusions. .

In addition to such a piercing method, the stool collection rod of the present invention can be used to collect a sample by rubbing the surface of feces with the coil-shaped projections. In this case, the feces enter the cavity through the gap on the side surface of the coil. Then, by rubbing the surface of the other part of the stool in the same manner, the stool that first entered moves in the cavity and can take in a new sample. As described above, since the stool can be collected by either scraping the surface of the stool or piercing the stool, an appropriate amount of the sample can be collected regardless of the hardness of the stool.

When collecting a sample by this abrasion,
In particular, it is preferable that the coil-shaped projection is formed by twisting the strip plate in a spiral shape. This is because the corners of the strip scratch the surface of the feces, and thus the faeces surface can be easily scraped off by rubbing.

Further, in these fecal sampling rods, it is preferable that a dent located at the back of an axial cavity formed at the coil center of the coil-like projection is formed on the tip end surface of the shaft portion. This is because by forming this depression, the feces first captured by the puncture method can be reliably retained in this depression.

When these stool collecting rods of the present invention are inserted into a container after the sample is collected and the coil-shaped projections are immersed in the liquid in the container, the gaps on the side surfaces of the coil-shaped projections and the holes at the tips are located at various locations. In, the sample and the liquid can be brought into contact with each other, and the sample can be easily dissolved in the liquid.

Further, the stool collection container of the present invention has one end closed and an opening at the other end, and a container body capable of containing a liquid for suspending feces, and the container body inserted into the container body. A capping member having a stool collecting rod and a sealing portion for sealing the opening, and an insertion hole that is provided in the container body and through which the shaft of the stool collecting rod can be inserted, and the sampling hole is inserted into the insertion hole. In a stool collection container that includes a partition member that partitions the interior of the container body into a liquid storage side and a cap member side by inserting a stool stick, the stool collection rod includes any one of the above-described stool collection rods. Is characterized by.

According to this stool collection container, as described above, the specimens collected from various places on the surface of the feces can be easily suspended in the liquid, and in particular, it is highly effective for early detection of colorectal cancer and the like. can do.

In this stool collection container, a filter member is arranged on the liquid storage side of the container body, and the filter member is sandwiched between the convex portion formed on the inner surface of the container body and the stool collection rod. It can be configured to be attached and fixed.

In a stool collection container having such a filter member, the filter member may float in the liquid to form a gap with the container body, which may not serve as a filter. However, as described above, the filter member is securely fixed in the container body by the structure in which the convex portion formed on the inner surface of the container body and the stool collecting rod are sandwiched and fixed, and functions as a filter member. You will never lose your ability.

Further, in the stool collection container of the present invention, the filter member is fixed to the liquid storage side by being sandwiched between the step portion formed on the inner surface of the container body and the partition member, and the sampling member is attached to the filter member. You may make it provide the hole with a bottom for receiving the shank of a flight stick. Also in this case, the filter member is firmly fixed in the container body.

Further, in these stool collection containers, the shaft portion of the stool collection rod is made to have a large diameter from the middle, and a taper portion is provided on the tip side of the large diameter portion so that the taper portion and the partition member are connected to each other. By closely contacting each other, the inside of the container body can be divided into a liquid storage side and a cap member side. With this configuration, the taper portion reliably separates the space on the cap member side from the space on the liquid storage side, and it is possible to eliminate the problem that the suspension leaks out of the container due to various circumstances during transportation.

Further, in these stool collection containers, small holes having a diameter smaller than the tip portion of the stool collection rod and radially extending from the small holes are formed on the opening side of the container body with respect to the partition member. A film member having a cut may be attached. By attaching this membrane member,
This is because it is possible to wipe off excess feces adhering to the surface of the shaft portion of the stool collection rod when collecting a sample. In particular, the shaft of the stool is inserted while opening a small hole with a diameter smaller than the tip of the stool, so the excess feces protruding not only from the side but also from the tip of the coiled protrusion can be wiped off. Can be taken.
