[Industrial applications]

 The present invention relates to a sample collecting tool capable of easily and accurately collecting and storing samples in clinical tests and medical research in a hygienic manner.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, spatula, match stick, toothpick, cotton swab and various other plastic molded products have been known as sample collecting tools used for clinical tests. The sample collected with this sample collection tool was transferred to an empty container and transported to the laboratory, or it was diluted by placing it in a separately prepared container containing the dissolving solution, and this diluted sample solution was the subject of the test. In addition, as a sample collecting tool for collecting a small amount of a fixed amount, there is known a device in which a groove or uneven portion is formed in a part of a rod-shaped device and the groove or uneven portion is filled with the sample. However, since this device fills the groove or uneven part with the sample for a fixed amount, it was necessary to squeeze the excess sample adhering to it by squeezing it with the edge of the container or paper. In addition to dropping the required sample, it was also extremely unsanitary because the sample adhered to the container.

In addition, in an inspection performed by diluting a sample with a lysis solution, a method is also known in which the lysis solution container is attached with a sample collection tool as a lid, and the sample collection tool is withdrawn from the container when the sample is collected. However, in this method, when the sample is taken out, the lysate in the core leaks out and the sample does not reach the specified dilution, or the sample cannot be collected sufficiently because the sample sampling tool is wet with the lysate. However, since the sample collecting tool is fixed in the solution, there is a problem that the sample stuck to the sample collecting tool is difficult to dissolve in the solution. Recently, a large number of simultaneous tests called mass screening have been widely performed, but this test is particularly simple, accurate, and hygienic, because ordinary people collect their samples or dilute them with lysis solution. However, the above-mentioned conventional sample collecting tools have not yet sufficiently met this requirement.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of such a point, and an object thereof is to provide a sample collection tool capable of collecting and diluting a sample simply, quantitatively, and sanitarily. .

[0005]

[Means for Solving the Problems]

 The configuration of the present invention in accordance with the above object is a sample collecting tool comprising a container body for containing a liquid for diluting a sample, and a sample collecting tube attached to the container body, wherein the sample collecting tube is a tubular body. A push rod is fitted to the lower end of the push rod, and a sample collecting portion for collecting and storing a sample is formed between the lower end of the push rod and the lower end of the tube body, and the lower end of the sample collection tube can be opened in the container body. It is characterized in that the closing means can be opened by facing or abutting against the closing means and pushing the push rod.

[0006] In short, the present invention forms a container of a constant volume with a tube and a push rod that fits into the tube, and collects a sample in this container to easily collect a sample of a constant volume. In addition to being able to collect samples, it was possible to add a fixed amount of sample to the diluent simply by pushing the push rod so that samples could be collected and diluted in a hygienic manner. Is the gist. In the present invention, the sample collecting tube is kept in a dry state before use because it is blocked from the lysing solution by the opening and closing means. Also, after collecting the sample, it is sufficient to insert it into the container body as it is, so it is not necessary to wipe off the extra sample adhering to the outer circumference of the tube, and even if it is wiped off, it will not affect the sample in the tube storage part at all. . After collecting the sample, insert the sample collection tube into the container body and press the push rod to open the closing means.The sample will be pushed into the lysate, so even ordinary people can collect the sample accurately and easily. can do.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a sample collecting tube 19 includes a tube body 17 in which a grasping portion 2, a fitting portion 16 and a tube portion 3 are integrally connected, and a push rod fitted to the tube body 17. 1, the tip 4 of the push rod 1 is thinly formed, and the push rod tip 4 and the inner wall of the tip of the tube 3 form a space of a constant volume, that is, a sample collecting portion 12. There is. As shown in FIG. 2, a small protrusion or step 13 is formed in the center of the container body 18, a concave stopper 6 is fixed to the small protrusion or step 13, and the bottom surface of the stopper 6 is A thin film 11 that can be opened is formed. The stopper 6 may be a sphere as long as it can be opened by the push rod 1, or the entire stopper 6 may be formed of a thin film, and is not particularly limited. When the stopper 6 is a sphere, the sphere may be configured to drop by the push rod 1, and the small protrusion or the step 13 is not particularly necessary. A drip section 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 liquid drop section 8 is formed at the center, and a manually foldable knob section 9 is formed at the lower end. There is. In the present invention, the drip unit 20 itself may have any structure.

[0008]

[Action]

 Next, an example in which the above-described sample collecting tool of the present invention is used as a fecal transport container used for mass screening for colorectal cancer will be shown. First, as shown in FIG. 1, the sample collecting tube 19 is pulled out from the container body 18, and the push rod 1 of the sample collecting tube 19 is pushed downward to cause the push rod tip 4 to project from the lower end, as shown in FIG. , Insert into feces 15 several times. At the time of the final insertion, if only the grasping part 2 is grasped and inserted into the feces 15 several times, the protruding push rod tip part 4 is pushed back into the tube part 3 together with the feces 15 and is inserted into the sample collecting part 12. A fixed amount of feces 15 can be collected.

Immediately after the stool collection, as shown in FIG. 3, the sample collection tube 19 is inserted into the container body 18 and sealed. Next, as shown in FIG. 4, when pushing the push rod 1 until the upper end 21 is buried, the push rod tip 4 breaks the thin film 11 of the stopper 6, and at the same time, the feces in the specimen collecting unit 12 is diluted. It is pushed out to the liquid 10 side. The feces 15 thus put into the liquid can be transported to the laboratory as they are. After transportation, the knob portion 9 at the lower end may be folded by hand and dropped through the filter 7 from the liquid droplet portion 8 for inspection. The sample collecting tool of the present invention is not limited to feces, and can collect all clinical samples of blood, urine and other body fluids, mucous membranes, cells and the like regardless of the type. However, specimens are often filth, and sufficient sealing is required during transportation. Therefore, it is possible to prevent the leakage of the specimen by making the entire device thin to make the fitting portion small, smoothing the sliding portion through the O-ring or the like and improving the sealing degree.

[0010]

【effect】

 As described above, according to the present invention, since the sample is collected and accommodated in the sample collecting portion having a constant volume formed between the tube body and the tip of the push rod, the sample can be easily and quantitatively analyzed. The sample can be collected without the need to wipe it off, and the sample can be diluted simply by opening the closing means with the push rod tip, so that even a general person can easily and simply collect a sample in a hygienic manner. It can be diluted for collection, and since the sample collection tube is maintained in a dry state, it has many advantages such as not adversely affecting sample collection.
