[Prior art]
Fecal occult blood tests are widely used for screening for colorectal cancer and rectal cancer, but in general, specimens are prepared and examined in hospitals based on stool collected at home.
In qualitative analysis using latex, because the amount of stool is restricted when preparing a sample, the specified stool collection rod is used. However, an accurate amount of stool can be collected using the stool collection rod. In the past, after collecting stool, the stool collection rod was wiped with paper etc. to remove the extra stool.
[0003]
However, the stool is dirty and has a strong odor, and when wiping it with paper, the stool may accidentally adhere to the hand, etc. The problem was often caused by the bad smell. In addition, in the case of a conventional specimen container containing a stool lysis buffer, even in the case of 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 the Liquid leakage sometimes occurred.
[0004]
In order to solve 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 obtained by sealing an elongate container body having a dropping portion at the tip with a lid with a stick. A rubber stopper having a stick insertion hole is fixed inside the container body, and the lid and the container body are fixed. The gap is sealed with an O-ring, and a malt and a filter are provided inside the dripping part. A stick is inserted into the insertion hole of the rubber plug to wipe off excess stool attached to the stick. It has become.
However, this stool collection container also has an expensive rubber stopper, and the rubber stopper must be fixed inside the container body. This increases the cost of the stool collection container, and drops the stool suspension. Since it is necessary to punch the sealing part of the dripping part with a punching machine, it takes time and there is a risk of dirtying the hand, and it is necessary to clean the punching machine every time. ing.
[0005]
Therefore, as a means for improving the shortcomings of the stool collection container of the above-mentioned Japanese Utility Model Laid-Open No. 2-140468, a container body containing a liquid and a lid provided with a stool collection bar as disclosed in JP-A-6-186227. And a dripping portion, and a separation wall provided on the upper part of the container body can wipe off an excessive stool sample of the stool collection rod and perforate a thin end surface at the tip of the dripping portion. Thus, a stool sample dissolved in a liquid is filtered through a filter provided at the lower part of the container body, and a stool collection container which can be dripped quantitatively, or an intermediate part as disclosed in JP-A-8-292189 Comprises a container body containing a liquid closed with a thin film, a sample collecting means, and a cap member that closes the lower part of the container body, and when the thin film is pierced by the sample collecting part of the sample collecting means Stool test A stool collection container has been proposed in which the sample filtrate can be quantitatively dropped onto the determination chromatograph by removing the nozzle closure provided on the cap member. Yes.
[0006]
However, in any case, these stool collection containers are in a state in which the tip of the stool collection stick to which the stool is attached is exposed, so that the stool sample is not suspended until it is suspended in the suspension. The hands and surroundings may be soiled, and when the stool collection rod with stool attached is inserted into the container containing the suspension, stool may be accidentally attached to the outer wall of the container. In addition, it is troublesome and unclean, and there is a risk of being infected with viruses and bacteria.
[0007]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a stool collection container having no possibility of being infected with a virus or bacteria and having good test accuracy and reproducibility.
[0008]
[Means for Solving the Problems]
As a result of intensive investigations in view of the above circumstances, the present inventors have housed the stool collection part in a suitable hollow container until the stool collection stick with the stool attached is inserted into the container containing the suspension. The present invention has been completed. That is, the present invention includes a stool collection rod having a gripping portion at a proximal end and a stool collection portion at a distal end, a tubular member having open ends at which both ends of the stool collection rod can be inserted and retracted, and a proximal end portion of the collection member. And a container main body having a dropping part closed by a closing membrane that can be pierced by a toilet bar and closed by a closing means that can be easily opened at the tip, and the outer wall of the toilet bar and the inner wall of the tubular member are liquid The stool collection container is configured to be closely engaged, and the distal end portion of the tubular member and the proximal end portion of the container body are liquid-tightly engaged. Here, as the dropping means closing means, a thin film that can be easily broken, a closing body that can be easily twisted off at the fragile part, a rubber cap, or the like is preferably employed.
[0009]
According to the above configuration, the stool collection part can be exposed from the tubular member or accommodated in the tubular member by moving the stool collection rod forward or backward in the tubular member. By storing the stool collection part in the tubular member until it is attached, contamination by the stool sample can be avoided. Further, since the stool collection part of the stool collection rod is inserted into the container body through the closure membrane of the container body, excess stool collected while the stool collection part pierces the closure membrane. The sample is removed and a fixed amount of stool sample is collected in the container body.
