BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sample collecting tool which can easily, accurately and hygienically collect and store a sample in a clinical test and medical research.

[0002]

2. Description of the Related Art Conventionally, a spatula, a matchstick, a toothpick, a cotton swab, and various other plastic molded articles have been known as sample collection tools used for clinical examinations. The sample collected by this sample collection tool is transferred to an empty container and transported to an inspection laboratory, or is diluted in a separately prepared container containing a dissolving solution, and the diluted sample solution is subjected to the test. In addition, as a sample collecting tool for collecting a small amount of a small amount, a device in which a groove or an uneven portion is formed in a part of a rod-shaped device and the sample is filled in the groove or the uneven portion has been known. However, since this instrument is designed to fill the groove or uneven portion with the sample to a certain amount, the excess sample must be removed by squeezing with the edge of the container or paper. In addition to dropping the sample that is essential, the sample adhered to the container and was extremely unsanitary.

[0003] In a test performed by diluting a sample with a lysis solution, a sample collection tool is attached to the lysis solution container as a lid.
It is also known to use a sample collection tool by extracting the sample from the container when collecting the sample.However, when extracting the sample, the essential lysate leaks out and the sample does not reach the specified dilution level. Since the sample collection device is wet, the sample cannot be sufficiently collected, or the sample collection device is fixed in the dissolving solution, so that the sample stuck to the sample collection device is difficult to dissolve in the solution. Recently, a large number of simultaneous tests called mass screening have been widely performed. In this test, the simplicity, accuracy, and hygiene are particularly high because ordinary people collect their own samples or dilute them with a lysis solution. Although required, the above-mentioned conventional sample collection tools have not yet sufficiently responded to this request.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a point, and a sample collection which can easily, quantitatively and sanitarily collect and dilute a sample. The purpose is to provide tools.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a sample collection tool having a container body for accommodating a liquid for diluting a sample, and a sample collection tube attached to the container body. The sample collection tube is formed by fitting a push rod to a tube, and forms a sample collection section for collecting and storing a sample between the lower end of the push rod and the lower end of the tube. The closing means can be opened by opposing or abutting the opening means of the container body and pressing the push rod.

In short, according to the present invention, a fixed volume storage section is formed by a tube and a push rod fitted into the tube, and a sample is collected in the storage section, thereby easily collecting a fixed volume sample. In addition to being able to do so, a fixed amount of sample can be put into the diluent just by pressing the push rod, and the sample can be collected and diluted in a sanitary manner. It is assumed that. In the present invention, the sample collection tube is kept dry before use, because the sample collection tube is blocked by the lysing solution and a closing means that can be opened. Further, after the sample is collected, it is only necessary to insert the sample into the container body as it is, so it is not necessary to particularly wipe off the extra sample attached to the outer periphery of the tube, and even if it is wiped, it does not affect the sample in the tube housing part at all. . After collecting the sample, insert the sample collection tube into the container body and press the push rod further to open the closing means, so that the sample is pushed into the dissolution solution, so that even ordinary people can collect and store the sample accurately and conveniently. Can be.

Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the sample collection tube 19 is
Tube 17 in which the tube, the fitting portion 16 and the tube portion 3 are integrally connected.
And a push rod 1 fitted into the tube 17. The tip 4 of the push rod 1 is formed to be thin, and the push rod tip 4 and the inner wall of the tip of the tube 3 define a fixed volume. A space, that is, a sample collection unit 12 is formed. As shown in FIG. 2, a small projection or step 13 is formed in the center of the container body 18, and a concave plug 6 is fixed to the small projection or step 13, and the bottom of the plug 6 is An openable thin film 11 is formed. The plug 6 may be a sphere or a thin film of the entire plug 6 as long as it can be opened by the push rod 1, and is not particularly limited. When the plug 6 is a sphere, the sphere may be configured to be dropped by the push rod 1, and the small projection or step 13 is not particularly required. The drip portion 20 at the lower end of the container body 18 is formed in a funnel shape, a filter 7 is mounted at the upper end, a drop portion 8 is formed at the center, and a knob 9 which can be folded by hand is formed at the lower end. I have. In the present invention, the drip portion 20 itself may be configured in any manner.

[0008]

Next, an example in which the sample collection device of the present invention is used as a stool transport container used for mass screening of colorectal cancer will be described. First, as shown in FIG. 1, the sample collection tube 19 is pulled out from the container main body 18, and the push rod 1 of the sample collection tube 19 is pushed downward, so that the push rod tip 4 protrudes from the lower end. Several times into feces 15. At the time of the last insertion, if the grasping part 2 is grasped only and inserted several times into the feces 15, the protruding push rod tip 4 is pushed back together with the feces 15 into the tube part 3, An amount of feces 15 can be collected.

Immediately after the collection of feces, a sample collection tube 19 is inserted into the container body 18 and sealed as shown in FIG. next,
As shown in FIG. 4, when the push rod 1 is pushed until the upper end 21 is buried, the push rod tip 4 breaks the thin film 11 of the plug 6, and at the same time, the feces in the sample collection unit 12 are moved toward the diluent 10. Extruded. Feces 1 thus injected into the liquid
5 can be transported to the laboratory as it is. After the transportation, the knob 9 at the lower end may be folded by hand and dropped from the droplet unit 8 through the filter 7 for inspection. The sample collection tool of the present invention is not limited to feces, blood, urine and other body fluids,
All clinical samples such as mucous membranes and cells can be collected regardless of their types. However, specimens are often contaminated, and a sufficient degree of sealing is required during transportation. Therefore, the fitting part is made smaller by making the whole instrument thinner,
The sliding part can be smoothened through an O-ring or the like, and the degree of sealing can be improved to prevent leakage of the specimen.

[0010]

[Effect] As described above, according to the present invention, the sample collection section of a fixed volume formed between the tube and the tip of the push rod is provided with:
Since the sample is collected and stored, the sample can be easily and quantitatively collected without necessity of wiping the sample, and the sample can be diluted simply by opening the closing means with the tip of the push rod. In addition to being able to easily and simply collect and dilute the sample in a sanitary manner even for ordinary people, since the sample collection tube is kept dry,
It has many advantages such as not adversely affecting sample collection.
