 The 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 to make a sample at a hospital for testing. In qualitative analysis using latex, the designated stool collection stick is used because there are restrictions on the amount of stool when preparing a sample, but even if a stool collection stick is used, an accurate amount of stool can be 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. As a result, the sample creator was often troubled by the bad odor, which was a problem. Also, with the conventional stool collection container containing the lysate, especially for some subjects such as the elderly, even if the lid was intended to be closed after stool collection, it could not be completely closed and was in transit. Liquid leakage may occur.

Therefore, as a solution to the above problems, a stool collection container disclosed in Japanese Utility Model Publication No. 2-140468 has been proposed. This stool collection container is an elongated 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 feature is that the space is sealed with an O-ring, and a malt and a filter are provided inside the drip section. Insert the stick into the insertion hole of the rubber stopper to wipe off excess stool adhering to the stick. It has become. However, this stool collection container also has a high cost because it has to be fixed in the body of the stool, which increases the cost of the stool collection container. It is necessary to perforate the sealing part of the dripping part with a perforator when dripping (a suspension), which is time-consuming and may soil the hands, and the perforator must be washed once. There are drawbacks such as

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, is lower in cost than the conventional one, requires less labor in manufacturing, and can open the drip portion of the suspension with a simple operation of twisting. It is intended to provide a stool collection container with good reproducibility of inspection.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a bottomed tubular body consisting of a solution storage portion having a mouth portion and a small diameter drip portion having a closed end, and a mouth portion of the tubular body having a stick insertion hole. It has a rubber plug that is inserted into and fixed to a rubber plug, and a plug portion that is similar to the stick insertion hole of the rubber plug and has an outer diameter larger than the inner diameter of the rubber plug. It consists of a cap member that is attached to the mouth of the body and a filter that is inserted into the drip portion of the tubular body adjacent to the solution storage portion, and the closed end is between the drip portion filter and the closed end. The stool collection container is provided with a rupture portion for separating the stool.

According to the above configuration, when a stool collection stick (having a shape similar to the stick insertion hole and having an outer diameter slightly larger than its inner diameter) is inserted into the stick insertion hole of the rubber stopper, Excessive stool attached to the stick is wiped clean with a stick insertion hole smaller than the outer diameter of the stool collection stick, so a fixed amount of stool sample is collected in the lysis solution in the lysis solution storage section. In addition, when the suspension is dropped onto the test device, it can be opened by a simple operation in which the tip of the lower part of the drop is simply twisted at the break. Further, by providing a liquid reservoir in the above configuration, the amount of the stool sample dropped can be quantified.
