Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool used for collecting feces and preparing a fecal suspension in clinical tests, particularly in examining fecal occult blood and viruses. It is used in the medical field.

[0002]

Similar to urine, feces are suitable as a non-invasive test sample, and are commonly used as a sample in some tests. Recently, a fecal occult blood test by an immunological method such as latex agglutination reaction, EIA, and RIA has attracted attention as a primary screening test method for cancer of the digestive system such as colon cancer.

In this test, it is necessary to collect a predetermined amount of feces and then suspend the feces in a liquid such as physiological saline. Conventionally, an inspector has performed this work, but it unnecessarily bothers the inspector and has a problem in hygiene. For this reason, in recent years, a fecal collection container or a fecal suspension preparation tool that allows the subject himself to relatively easily and easily perform quantitative collection of feces to preparation of the suspension thereof. It has been proposed (Japanese Utility Model Publication No. 62-69160).

This stool collection container comprises a container body capable of containing a liquid for suspending feces and a lid. One lid for stool collection inserted into the container body is fixed to the lid, and at least one of a notch, a recess, or a through hole is provided as a stool storage portion at the tip of the stool collection rod. There is. When collecting stool, remove the lid from the container body, pierce the stool with the tip of the stool collection rod fixed to the lid, and wipe off excess stool to retain a predetermined amount of stool in the stool storage unit. .. After that, the feces suspension can be prepared by sealing the container body with the lid. That is, since the stool storage part is immersed in the liquid in the container body, by shaking the container body, the stool held in the stool storage part is easily suspended in the liquid in the container body. .. The suspension thus obtained is taken out of the container through a filter by making a hole in the tip of the lid or by cutting off the tip, and provided for inspection.

On the other hand, the stool collection container described in Japanese Utility Model Publication No. 1-85668 is used for the same purpose as the above-mentioned container, but a groove is provided on the bottom surface of the tip of the stool collection rod. Therefore, it has an effect that the stool can be collected reliably and evenly when the stool is pierced with the sampling rod.

However, in any of the above-mentioned stool collection containers, when the excess stool attached to the tip of the stool collection rod is wiped off with toilet paper or the like, if the stool is wiped off tightly, one Parts may be scraped off, resulting in inaccurate inspections. In addition, when wiped off tightly, the fecal collection rod fixed to the lid may come off the lid or be damaged. Furthermore, it is difficult to collect a certain amount of stool at once even with a stool collection rod that has a groove for collecting and storing stool on the side of the tip. The stick is wiped with paper etc. to remove excess feces adhering to the part other than the groove.

However, this operation is not only troublesome for the inspector, but also has a problem in hygiene such that the hand is soiled during wiping. In any case, conventional stool suspension preparation tools, stool collection tools and stool collection rods have complicated operations for stool collection and inspection, and there is a risk that the inspector's hands will be contaminated with stool and its suspension. However, it has a problem in any one or more of that it is unhygienic.

A first object of the present invention is to provide a hygienic fecal suspension preparation device which is easy to operate for fecal collection and examination, and is free from the possibility of soiling the inspector's hand with feces or its suspension. Is provided. A second object of the present invention is to provide a stool collection rod and a stool collection tool which are capable of easily collecting and storing a fixed amount of stool and which are also preferable in terms of hygiene.

[0009]

Means for Solving the Problems As a result of repeated studies to achieve the above object, the present inventors have adopted a feces storage container having a specific structure or a feces suspension preparation tool, and collecting feces. It has been found that the first object can be achieved by separating the rod from the lid, rather than fixing it to the lid. Further, by slidably fitting the stool wiping tool on a stool collection rod provided with a groove for collecting and storing stool on the side surface of the tip, more preferably, the stool collection rod having a lid It has been found that the second purpose can be achieved by using the container together.

The present invention has been completed on the basis of the above new findings. First of all, the feces suspension preparation tool of the present invention comprises a container body containing a liquid for feces suspension, A first lid provided in the opening of the container body and having a means for filtering the fecal suspension therein, and a second lid capable of sealing the opening provided in the upper portion of the first lid. It can be stored in the stool storage container consisting of the lid body and the stool storage container,
In addition, it is provided with a separate stool collecting rod having a plurality of grooves for collecting and storing stool on the side surface.

Secondly, the stool collection rod of the present invention is a stool collection rod having a groove for collecting and storing the stool on the side surface of the tip, and a stool wiping tool is slidably fitted therein. It is characterized by that. Furthermore, the above-mentioned stool collection rod can be used in combination with a stool collection container having a lid to provide a more suitable stool collection tool. Furthermore, a more convenient stool collection tool can be provided by combining the stool suspension preparation tool of the first invention and the stool collection rod or stool collection tool of the second invention.

EXAMPLES The feces collecting tool of the present invention will be described more specifically with reference to the drawings. FIG. 1 is a cross-sectional view showing an example of a feces storage container constituting the feces suspension preparation tool of the present invention. The feces storage container A has a container body 1, a first lid body 2 and a second lid body 3. The first lid 2 is screwed into the upper opening of the container body 1 and is mounted in a liquid-tight manner. As the mounting means of the first lid body 2, in addition to the above-mentioned screw attachment, means such as crown attachment, fitting attachment, and insertion attachment can be arbitrarily adopted. Inside the first lid 2, a filter 4 such as sponge or filter paper is provided as a means for filtering the fecal suspension, and a nozzle-shaped opening is provided in the upper part. The second lid 3 is mounted in a liquid-tight manner by being screwed into a nozzle-shaped opening provided in the upper portion of the first lid 2, and the mounting is performed by the mounting means of the first lid 2 described above. The same means as can be used.

A liquid 5 for suspending feces such as physiological saline or various buffers is contained in the container body 1. As a material for the container body 1, a soft plastic material such as polyethylene or polypropylene is preferable for the container body 1. A relatively hard plastic material is preferably used for the first lid 2 and the second lid 3.

FIG. 2 is a perspective view showing an example of a fecal sampling rod constituting the feces suspension preparation tool of the present invention. The stool collection rod 6 is provided with a plurality of grooves 7 for holding the stool after collecting the stool, and an elongated spatula-shaped one is preferable so that the stool collection rod 6 can be stored in the container from the opening of the container body 1. .. The groove can be provided in any shape. Although the width and depth of the groove are not particularly limited, a width of 0.1 to 0.1 mm is provided so that the feces stored in the groove cannot be wiped off when the excess feces are wiped off.
The width of the groove is preferably 1.0 mm, and the width / depth of the groove is preferably in the range of 0.5 to 1.0, and the bottom of the groove is preferably round so that faeces can be easily dissolved.

By the way, unlike the case of the blood test or the urine test, the test substance is not always uniformly distributed in the stool in the fecal test. It may be preferable to collect from. In response to such a request, if there is only one stool collection stick, it is necessary to stab at several places, but the stool collection part is filled with one puncture, and then the stool collection stick is separated from the stool. There is a problem that the stool of the part cannot be collected even if the part is pierced.

Therefore, in the fecal suspension preparation tool of the present invention, it is preferable to use at least two fecal collection rods 6 to reliably and quantitatively collect the required amount of feces from several locations. This also applies to the fecal collection rod shown in FIG. 3 described later. Examples of the material of the fecal collection rod 6 include polystyrene, hard plastic such as ABS resin, metal, glass, and wood. The fecal collection rod 6 is a separate body, but the separate body here means a state in which it is not fixed to the feces storage container A. However, it may be detachably attached to the feces storage container A by an appropriate means.

The stool suspension preparation tool, stool collection tool and stool collection rod of the present invention are specifically used as follows. A predetermined amount of the liquid 5 for suspending feces is put in the container body 1 of the feces storage container A, the opening is closed by the first lid 2, and the nozzle-like opening at the tip of the first lid 2 is further placed. The feces storage container A is handed to the subject in a state in which is closed with the second lid 3. At this time, the fecal collection rod 6 (preferably two or more) is also handed to the subject. The subject who receives the stool collection rod 6 and the stool collection container A first pierces the stool with the tip portion of the first stool collection rod 6 and rubs the groove 7 on the stool. As a result, feces are stored in the groove 7. Next, the excess feces adhering to the portions other than the groove 7 are wiped off with toilet paper or the like, and the feces corresponding to the volume of the groove 7 are quantitatively held on the tip portion of the feces sampling rod 6. next,
Feces are collected from another location of the feces in the same manner as above using the second fecal collection rod 6.

Next, each feces sampling rod 6 from which feces were collected,
The first lid 2 of the feces storage container A is opened and inserted, and the container body 1 is closed with the first lid 2. Next, the feces storage container A is passed to the inspector by mail or the like with the feces collection rod 6 contained therein, but since the feces storage container A is liquid-tightly sealed, it is hygienic. It can be delivered in a simple state. The inspector who has received the fecal collection container A shakes the container body lightly to suspend and dissolve the feces contained in the groove 7 of the fecal collection rod 6 in the fecal suspension liquid 5.

Next, the inspector opens the second lid 3 of the stool storage container A and presses the side surface of the stool storage container A in which the stool collection rod 6 is contained to take out the liquid in which the stool is suspended. At this time, the fecal suspension in the container body 1 passes through the filter 4 provided inside the first lid body 2 and the insoluble matter is filtered off. At this time, if the opening at the tip of the first lid 2 is made into a drip mouth, the amount of fecal suspension to be taken out can be adjusted by adjusting the diameter of the drip, so that the inspector can obtain the necessary amount of feces. The suspension can be easily removed. Further, the inspector does not stain his hands with the feces or the solution thereof after receiving the fecal collection container A.
