Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention collects stool used as a sample for clinical examination, particularly a sample for detecting occult blood, enzyme, virus, etc. The present invention relates to a stool collection container that is convenient for transportation in a suspended state.

[0002]

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, since the stool is dirty and has a strong odor, the stool may accidentally adhere to a hand when wiped with paper or the like, and the cap of the stool collection container may be opened to make a stool collection stick. Since the sample was taken, the creator of the sample often suffered from a bad odor, which was a problem. 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 leaked 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 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, and the space between the lid and the container body is fixed. It is characterized by sealing the O-ring with a malt and a filter inside the drip part, so that the stick can be inserted into the insertion hole of the rubber stopper to wipe off excess stool attached to the stick. ing. However, this stool collection container also has a high cost because it has to be fixed in the container body, which increases the cost of the stool collection container. It is necessary to pierce the sealing part of the dripping part with a perforator when dripping the liquid), which may be time-consuming and dirty, and the perforator needs to be washed once. It has drawbacks.

[0005]

The present invention has been made in view of the above circumstances and has a lower cost than the conventional one.
It is an object of the present invention to provide a stool collection container in which the hollow portion of the nozzle can be opened by a simple operation of just twisting it without the labor required for manufacturing, and which has good reproducibility of inspection.
