2. Description of the Related Art A fecal occult blood test is widely used for screening for colorectal cancer and rectal cancer, but in general, a stool collected at home is used as a sample for testing in a hospital. In qualitative analysis using latex, the designated stool collection stick is used because there is a restriction on the amount of stool preparation when preparing a sample, but even if a stool collection stick is used, an accurate amount of stool is collected. This is difficult, and in the past, after collecting stool, excess stool was removed by wiping the stool stick with paper or the like.

However, the stool is dirty and has a strong odor, and when wiped off with paper or the like, the stool may accidentally adhere to the hands, and the cap of the stool collection container is opened to collect it on the stool collection stick. Therefore, it was a problem that the creator of the sample often suffers from a bad odor. In addition, with the conventional stool collection container containing the solution, especially for some subjects such as elderly people, even if the lid was intended to be closed after stool collection, it could not be completely closed and leakage occurred during transportation. May occur.

Therefore, as a means for solving the above problems, a stool collection container disclosed in Japanese Utility Model Laid-Open No. 2-140468 has been proposed. This stool collection container is a long and narrow container body having a drip at the tip sealed with a lid with a stick, and a rubber stopper having a stick insertion hole is fixed inside the container body to separate the lid and the container body. The space between them is sealed with an O-ring, and the malt and filter are provided inside the drip part, so that you can insert the stick into the insertion hole of the rubber stopper and wipe off the excess stool attached to the stick. Has become. However, this stool collection container also has an expensive rubber stopper, and since the rubber stopper must be fixed inside the container body, the cost of the stool collection container is high, and the stool suspension (hereinafter, simply suspended) is required. It is necessary to perforate the sealing part of the dripping part with a perforator when dripping the turbid liquid), which is time-consuming, and there is a risk of soiling the hands, and it is necessary to clean the perforator once. There are some drawbacks such as being present.

[0005]

The present invention has been made in view of the above circumstances and has a lower cost than the conventional one.
The purpose of the present invention is to provide a stool collection container that requires no labor for production, can open the dripping portion of the suspension with a simple operation of twisting, has a good inspection accuracy, and has good reproducibility. To do.

[0006]

In order to solve the above-mentioned problems, the present invention provides a flat sample container having a small-diameter tubular dropping portion at its bottom, and a mouthpiece of the sample container. A cap member, the drip opening at the tip of the drip portion is closed by an easily openable closing member, and the lumen except the portion adjacent to the drip opening is filled with a filter. The stool collection container is characterized in that a pair of stool collection stick insertion ports that are symmetrical with respect to the short axis of the sample storage container are provided on the top surface of the member. Further, a stool collection container set in which the stool dissolution buffer is stored in the above stool collection container and the stool collection stick insertion opening is liquid-tightly closed with a stool collection stick shaped to match the insertion opening is adopted. is doing.

[0007]

According to the construction of the above-mentioned stool collection container set, the stool collection stick is shaped to fit the stool collection stick insertion opening, and the stool collection stick insertion opening is closed in a liquid-tight manner. When the stool stick is inserted into the stool stick insertion slot, excess stool attached to the stool collection stick is scraped off neatly at the stool collection stick slot, and a fixed amount of stool sample is collected in the sample storage container. Further, when the suspension is dropped onto the test device, the dropping port can be opened by a simple operation such as twisting off the closing member that closes the dropping port. Further, since two fecal sampling stick insertion ports are provided so that fecal samples on the deep part and the surface of excreted feces can be respectively collected and stored, highly accurate screening can be performed.
