DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stool collection rod for collecting feces as a specimen, and a stool collection for storing a specimen collected by the stool collection rod and transporting the specimen to a laboratory such as a hospital or a health center. It concerns a container.

[0002]

2. Description of the Related Art Conventionally, as a stool collection rod used for collecting feces as a specimen, for example, a notch, a concave portion, or a through hole is provided near a tip of a shaft portion as described in Japanese Utility Model Publication No. 5-17652. Are known.

[0003] Such a conventional stool collection rod 100 is shown in FIG.
As shown in (A) to (C), the tip of the shaft 101 is pierced into the stool so that the stool 110 is attached to the notch 103, the recess 105, or the through hole 107 provided near the tip of the shaft 101. The specimen is collected by scooping it.

[0004]

In the examination of colorectal cancer and the like, it is desired to collect a specimen from the surface of feces coming into contact with the intestinal wall. In collecting the stool, it is desired to secure samples at the surface of various parts of the feces.

[0005] However, in the conventional stool collection bar 100,
There is a problem that it is difficult to reliably collect a sample from the vicinity of the surface of the stool, and that once the stool is clogged in the notch 103 or the concave portion 105, the sample cannot be collected from another location.

In addition, the one having the through hole 107 has a problem that it is difficult to dissolve when immersed in the liquid in the container body.

[0007] Further, with 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 application has previously filed Japanese Patent Application No.
No. 83260 (JP-A-9-126959),
A stool bar with a stool brush at the tip of the shaft has been proposed. A stool collection brush equipped with a stool collection brush can easily collect a sample from the vicinity of the surface by rubbing the surface of the stool with a stool collection brush, and can rub the sample from various places by rubbing various parts of the stool. Can be collected.
In addition, there is no unevenness in the sampling fee due to the hardness of the stool, and further, the stool is easily dissolved when immersed in the liquid in the container, and is very excellent.

[0009] However, in this feces collection brush system, the feces collection rod cannot be easily manufactured by injection molding or the like, and there is a problem that the cost is increased while having excellent performance.

Therefore, in the present invention, as in the case of the stool collection brush method, a sample can be easily collected from the vicinity of the stool surface, and a sample can be collected from various places of the stool. The purpose is to provide a stool that is easy to dissolve when immersed in a liquid, and that the sample can be reliably collected regardless of the hardness of the stool. It is another object of the present invention to provide a stool collection container using such a stool collection rod.

[0011]

A stool collection rod according to the present invention is a stool collection rod for collecting feces as a specimen sample, wherein a coil-shaped projection is provided at the tip of a shaft portion, and the coil-shaped projection is provided in the coil-shaped projection. The stool is configured to enter and hold feces. Here, the coil-shaped projection has a cavity extending in the axial direction at the center, and further refers to one formed with a gap of a predetermined width through which feces can enter and exit from the side,
It has the same shape as the state where no compression force is applied to the compression coil spring.

According to this stool collection rod, the stool can penetrate into the internal cavity from the hole formed at the tip of the coiled projection by piercing the tip of the shaft into the stool. At this time, since there is a gap on the side surface of the coil, air does not accumulate in the cavity and does not disturb the cavity, and the specimen can be easily collected by piercing. Also, by piercing another part of the stool, the first stool can be pushed into the interior of the cavity while part of the stool escapes from the side gap, and further new stool can be taken into the coil-shaped protrusion. .

In addition to the piercing method, the stool collection rod of the present invention can be used to collect a specimen by rubbing the surface of feces with the coil-shaped projection. In this case, feces enter the cavity from the gap on the side surface of the coil. Then, by rubbing the surface of the other part of the feces in the same manner, the feces that have entered first move in the cavity and can take in a new specimen. In this manner, feces can be collected by rubbing or piercing the surface of the feces, so that an appropriate amount of specimen can be collected regardless of the hardness of the feces.

When the specimen is collected by this scraping,
In particular, it is preferable that the coil-shaped projections have a shape in which the strip is twisted into a spiral shape. This is because the corners of the strip scratch the stool surface, so that the stool surface can be easily scraped off.

[0015] In these stool collection rods, it is preferable that a recess is formed in the distal end surface of the shaft portion, which is located deep in an axial cavity formed at the coil center of the coil-shaped projection. By forming the depression, feces that have been initially taken in by the piercing method can be reliably held in the depression.

When the stool collection rod of the present invention is inserted into a container after collecting a specimen, and the portion of the coil-shaped projection is immersed in the liquid in the container, the gap on the side surface of the coil-shaped projection and the various points of the hole at the tip end. In the above, the sample and the liquid can be brought into contact, and the sample can be easily dissolved into the liquid.

Further, the stool collection container of the present invention has a container body closed at one end and having an opening at the other end and capable of storing a liquid for suspending feces, and a container inserted into the container body. A cap member having a sealing portion for sealing the opening portion and the opening portion, and a through-hole provided in the container main body and through which a shaft portion of the stool collection rod can be inserted; In a stool container provided with a partition member for partitioning the inside of the container body into a liquid storage side and a cap member side by inserting a stool bar, any one of the above-mentioned stool bars is provided as a stool bar. It is characterized by.

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

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

In a stool container having such a filter member, there is a case where the filter member floats in the liquid and a gap is formed between the container and the container body, and does not function as a filter. However, as described above, the filter member is securely fixed in the container body by being sandwiched and fixed between the convex portion formed on the inner surface of the container body and the stool collection rod, and functions as a filter member. Is not lost.

Further, in the stool collection container of the present invention, the filter member is fixed to the liquid storage side by being sandwiched between a step formed on the inner surface of the container main body and the partition member. A bottomed hole for receiving the shaft of the toilet rod may be provided. 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 increased in diameter from the middle, and a tapered portion is provided at the tip end of the large diameter portion, so that the tapered portion and the partition member are separated from each other. By bringing the container body into close contact, the inside of the container body can be divided into a liquid storage side and a cap member side. According to such a configuration, the cap member side space is reliably separated from the liquid storage side space by the tapered portion, and it is possible to eliminate a problem that the suspension leaks out of the container due to various circumstances during transportation.

In these feces collection containers, a small hole having a diameter smaller than the distal end of the feces collection rod is formed on the opening side of the container body with respect to the partition member, and is formed radially from the small hole. A configuration may be adopted in which a film member having a notch is attached. By attaching this membrane member,
This is because feces that have excessively adhered to the surface of the shaft of the stool collection rod can be wiped off during sample collection. In particular, since the shaft portion of the stool bar is inserted while pushing a small hole having a smaller diameter than the tip portion of the stool bar, the excess feces protruding not only from the side surface but also from the tip of the coil-shaped protrusion are wiped off. Can be taken.
