Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for using a container for collecting and transporting feces as a sample for clinical examination, particularly for detecting occult blood, enzymes, viruses and the like in feces, and for preparing a suspension thereof. It is a thing. More specifically, the present invention relates to a method of using a stool collection container that can easily carry out all steps from quantitative collection of stool to preparation of a test sample solution by filtration of a stool suspension.

[0002]

BACKGROUND OF THE INVENTION Feces, like urine, are suitable as a non-invasive test sample, and are widely used as a sample in some tests. Above all, the detection of occult blood in the feces is very important for the diagnosis of digestive system diseases, especially ulcers of the stomach and duodenum, cancer and the like. As a method for detecting occult blood in feces, a recently reported detection method based on the immunological reaction principle (Japanese Patent Laid-Open No. 59-125064) is compared with a conventional detection method using a test strip using a guaiac reagent. It excels in specificity and sensitivity, and is attracting attention as a new screening method for the above patients.

[0003]

By the way, in order to carry out the method of detecting fecal occult blood based on this immunological principle,
It is necessary to collect feces quantitatively to some extent in advance and suspend them in an appropriate liquid to prepare a fecal suspension. Because this immunological test reagent is set to have a sensitivity according to the amount of feces that can be expected, that is, the amount of feces, if the amount of feces to be tested is too small, the sensitivity is lowered, while if it is too large, it is transported. It is inconvenient, causes a bad odor, and causes a problem in disposal of an extra sample.

The applicant of the present invention has devised a stool collection container described in Japanese Utility Model Application Laid-Open No. 62-69160 for the purpose of eliminating such inconvenience. By using the fecal collection container of this invention,
It is possible to limit the amount of collected feces to some extent by the notch, the recess, or the through hole formed near the tip of the collecting rod. However, there is a limit to controlling the amount of collected feces only by the tip structure of the collecting rod, and for example, the collected amount may be excessive or insufficient depending on the physical properties of feces. The present invention provides a method of using a stool collection container, which does not impair the convenience of using the stool collection container described in Japanese Utility Model Laid-Open No. Sho 62-69160, and which enables more complete control of the stool collection volume. The purpose is to provide.

It is a figure. The structure of the stool collection container will be described below.

The shape of the container body 2 of the stool collection container is such that when the cap A4 is connected with the volume capable of containing the liquid 1 in an amount necessary to suspend the stool at a desired concentration, the collection rod is fixed to this. The shape is not particularly limited to a cylindrical shape, a prismatic shape, etc., as long as 3 has a length that cannot be used. The material is polyethylene, polyvinyl chloride,
Polypropylene or the like can be used. In particular, a stool collection container formed of a flexible material such as polyethylene or polypropylene is convenient because the stool suspension can be easily pushed out.

As the liquid 1 inside the container body, any liquid such as physiological saline or various buffer solutions may be used. Further, if it does not affect the analysis result, it is possible to add a dye, a preservative, a deodorant, etc., if necessary.

As means for sealing the container body 2 and the cap A4, there are a screwing type and a fitting type.

The drip unit 6 provided with the filter 5 can have the following structure, for example. That is, as shown in FIG. 1, a cap B9 having a protruding portion 10 accommodating a filter 5 therein is connected to the container body 2 by means capable of sealing, or a part of the container body 2 is protruded outward, For example, the filter 5 is housed in the inner space of the protruding portion (FIG. 2).

The filter 5 in the drip section 6 of the fecal collection container ensures that the fecal suspension is filtered when the drip suspension is dropped by providing a drip opening to the outside of the filter 5 of the drip section 6 by piercing or the like. Installed in the appropriate position. On the other hand, the portion of the drip portion 6 outside the filter 5 is a portion where a drip port is provided in the inspection as described later, so it is convenient to make it thin to facilitate perforation. The drip opening may be provided by previously making a scratch on the projecting portion in addition to the perforation and breaking the scratched portion. The location and shape of the drip unit 6 are limited as long as they satisfy the condition that the feces suspension can be dropped through the filter 5 when the drip port is provided as described above. Any material may be used, and the material is not particularly limited.

On the other hand, the filter 5 in the fecal collection container
Since it is installed for the purpose of filtering undigested solids that interfere with the inspection, the material is not particularly limited as long as it is inert to the substance to be analyzed. Specifically, porous materials such as sponge and filter paper,
