Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a clinical test sample,
In particular, it is convenient to collect stool used as a sample for detecting occult blood, enzymes, viruses, etc., and transport the quantified amount in a stool lysis buffer in a container in a suspended state. It relates to a stool container.

[0002]

2. Description of the Related Art Fecal occult blood testing is widely used for screening for colorectal cancer and rectal cancer. In general, a specimen is prepared and inspected at a hospital based on stool collected at home. In qualitative analysis using latex, there is a restriction on the amount of stool at the time of sample preparation, so the designated stool bar is used, but the exact amount of stool is collected using the stool bar In the past, it was difficult to remove excess stool by collecting the stool and then wiping the stool stick with paper or the like.

[0003] However, the stool is dirty and has a strong smell. When the stool is wiped off with paper or the like, the stool may accidentally adhere to the hand or the like. The creator of the specimen often suffered from bad smell, which was a problem. In the case of a conventional sample container containing a stool lysis buffer, especially for some subjects such as the elderly, even if the lid is intended to be closed after stool collection, it cannot be completely closed, and during transportation. Liquid leakage sometimes occurred.

[0004] To solve the above-mentioned problem, Japanese Unexamined Utility Model Publication No. 2-140468 discloses a stool collection container. This stool collection container is one in which an elongated container main body having a drip portion at the tip is sealed with a lid with a stick, a rubber stopper having a stick insertion hole is fixed inside the container main body, and the lid and the container main body are fixed. The gap is sealed with an O-ring, and a malt and a filter are provided inside the drip part. Insert a stick into the rubber stopper insertion hole and wipe off excess stool attached to the stick. Has become. However, this collection container also requires an expensive rubber stopper, and the rubber stopper must be fixed inside the container body, so that the cost of the collection container increases, and when dropping a stool suspension, Since it is necessary to pierce the sealing part of the drip part with a piercing machine, it is troublesome and there is a risk of soiling the hand, and that the piercing machine needs to be washed each time,
It has disadvantages such as.

In order to improve the disadvantages of the stool container disclosed in Japanese Utility Model Laid-Open Publication No. 2-140468, Japanese Unexamined Patent Publication No.
As disclosed in JP-A-186227, the container includes a container body containing a liquid, a lid provided with a stool collection rod, and a drip portion. By allowing the stool sample to be wiped off, and by piercing the thin end face of the tip of the drip portion, the stool sample dissolved by the liquid is filtered by the filter provided at the lower part of the container body, and is quantitatively dropped. And a container body containing a liquid whose intermediate part is closed with a thin film, a sampling means, and a cap for closing a lower part of the container body as disclosed in JP-A-8-292189. A thin film piercing the thin film by the sampling portion of the sampling means so that excess stool sample of the sampling means can be wiped off, and a closing portion of a nozzle provided on the cap member is removed. And a, have been proposed feces collection containers to be dropped into quantitatively on determination chromatographic specimen filtrate.

[0006] However, all of these stool collection containers are suitable for collecting solid stool, but are not suitable for collecting liquid diarrhea stool. There is a need for a stool collection container that is suitable for detecting the bacteria of a patient having a stool.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a lower cost than conventional ones.
An object of the present invention is to provide a stool collection container having good test accuracy and reproducibility, particularly suitable for collecting liquid diarrhea.

[0008]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, have conceived to adopt a stool collection means provided with suction means instead of the conventional stool collection rod. Thus, the present invention has been completed. That is, the present invention provides a syringe-like defecation means, a defecation means insertion port and a drip port at the base end and the distal end, respectively, the base end of which has a through-hole through which the defecation means can be inserted in a liquid-tight manner. It is a stool collection container including a container body partitioned by a partition wall having the stool. Here, the stool collection means includes a cylinder having a means for engaging with the container body at the base end, and a plunger that is inserted from the base end to the tip of the cylinder, and slides in close contact with the inner wall of the cylinder at the tip. Preferably, a protrusion for stopping sliding of the plunger may be provided at a predetermined position on the inner wall of the cylinder. The stool collection container of the present invention mounts a fitting member of a predetermined length having a groove having a shape complementary to the cylinder insertion portion of the plunger on the base end side of the cylinder insertion portion of the plunger, and collects stool on the distal end side of the cylinder. A concave portion for use may be formed.
