[Industrial applications]

 The present invention relates to a sample container equipped with a sample collecting tool that can easily and accurately collect and store a sample in the fields of clinical examination and medical research.

[0002]

[Prior Art]

 Examples of test sample collection devices used for clinical tests include spatulas, matchsticks, toothpicks, cotton swabs, and various other plastic molded products.The samples collected by these are transferred into empty containers and transported to a laboratory. Alternatively, it is placed in a container containing a liquid prepared separately for suspension or dissolution, and a suspension or solution of the sample is prepared for testing. However, in order to perform an accurate test, it is necessary to adjust the amount of sample to be collected and the concentration of the test solution within a predetermined range suitable for the test, but an appropriate product that is still practical is realized. Not not.

[0003]

[Problems to be solved by the device]

 Conventionally, as a device for collecting a fixed amount of a small amount or a small amount of a sample, many methods are performed by forming a groove or unevenness in a part of the molded instrument and filling the part with the sample, which is accurate. To prevent this, excess adhered sample is removed by squeezing the edges of the container and paper. In this case, even the most important sample is removed, and if the sample adheres to the outside of the container, it is extremely uncomfortable and unsanitary. In addition, in the test performed after dissolving or suspending the sample in a liquid, attach the sample collection tool to the container containing the solution with the lid attached, and remove it together with the lid from the container when collecting the sample. A type to be used has also been devised, but when it is withdrawn, the lysate in the core leaks out and the sample is not diluted to the specified concentration, or the sample collection device has been in contact with the liquid from the beginning. The sample is not sufficiently collected because it is wet and the sample collection device is fixed at a predetermined position in the container containing the liquid. Alternatively, it can be extremely difficult to dissolve. Further, in the simultaneous examination of a large number of samples called mass screening, it is necessary for an ordinary person who is not accustomed to handling the sample to process his or her own sample, and in particular, simplicity, accuracy and cleanliness are required.

[0004]

[Means for Solving the Problems]

 The present invention is intended to solve the above problems. In the present invention, by removing the lid, the exposed portion of the rod-shaped sample collecting tool is inserted into the specimen, the specimen is filled in the collecting portion provided at the tip of the rod, and then the lid is reapplied. The specimen sampling rod is pushed into the container body, and at this time, the excess specimen is sealed in the space formed by the outer wall of the narrow end portion and the inner wall of the lid portion in the container. Since both the collected sample and sample sampling rod are released into the container body, if the sample is not dissolved or is filled with suspended liquid, the sample sampling rod will function as an agitator by shaking the container. Also, the reliability of dissolution or suspension is enhanced. Since the above can be easily performed as a series of operations, even a general person who is not accustomed to handling can easily and accurately collect a sample.

[0005]

[Constitution and operation of device]

 The sample collecting rod is slidably projected from a thin tube portion provided at one end of the container body, and fixed by a small projection or an O-ring from the inner wall of the container to form a stopper. Further, a lid is provided so as to cover the sample collecting rod. This lid also serves as protection of the specimen collecting rod. A cylinder is provided between the lid and the container lid stopper, but this cylinder is discarded after the lid is removed during use. Since the cylinder to be discarded is to secure the space between the lid and the container lid stopper before use, it can be substituted by changing the structure of other articles or related parts. At the tip of the sample-picking rod, a part that can be filled with the sample, such as a notch, groove, or hole, should be provided. By forming the container body into an elongated shape, the whole body becomes a sample collection tool that is easy to operate. After collecting the specimen, the lid is put on again and the lid is tightened up to the lid stopper part of the container body, and the protrusion provided inside the lid causes the specimen collecting rod to be ejected into the container body. The protrusion on the inside of the lid body is directly inserted into the thin tube portion of the container to form a plug body. The other end of the container body is sealed with another lid, stopper or welding, and if the liquid for dissolution or suspension is filled, the other end should be filled with droplets necessary for inspection. It is possible to provide a thin tube part so that the amount can be taken out, and to add a filtering function to the inside.

【Example】

 Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. Reference numeral 1 denotes a lid, which is fixed so as to slide with the base of the container thin tube portion 3. The cylindrical body 4 is fixed to the position of the lid before use, and is covered to protect the specimen collecting rod 2 and maintain its position. The sample collecting rod 2 is pressed and fixed by an inner wall 11 of the tip portion of the container thin tube portion 3 and an O-ring 10 which is in sliding contact with the inner wall step portion 12 of the container 3, and also serves as a stopper of the container body. The container body is composed of a container thin tube part 3 and an outer cylinder 16 of a collected sample holding part 5 (which becomes a liquid storage part in the case of suspension or dissolution), and is closely contacted by a fitting part 14 and an O-ring 8. There is. When the sample is dissolved and suspended, the other end 15 of the outer cylinder 16 is inserted with a filter medium 6 (addition of a continuous foamed or mesh-like object) in order to add a filtering function, if necessary. First, the tip end portion 15 having an inner diameter suitable for forming a desired amount of droplets can be provided. It is preferable that the tip portion 15 has a structure in which it is sealed by welding or another lid or stopper. The container thin tube portion 3 has a container lid body stopping portion 7 so as to be in close contact with the lid body 1, and a step crimping portion 13 formed by a screw or a groove and a protrusion.

When collecting a sample, first, the lid 1 is removed, and at the same time, the cylinder 4 is discarded. Then, the exposed sample collecting rod 2 is pierced or entangled with the sample to fill the sample in the sampled site provided at the tip of the sample 2. The lid 1 is put on the original position again, and the container lid stopper 7 is tightened. By this operation, the sample-picking rod 2 is pushed by the inner protrusion 9 of the lid 1 and released into the sample-holding section 5. At the same time, the excess sample is scraped off by the inner wall 11 of the tip portion, and is hermetically retained in the gap formed by the lid 1 and the container thin tube portion 3, that is, the excess sample retaining section 17. When the lid 1 is tightened, the inner protrusion 9 is fitted to the inner wall 11 of the distal end portion and serves as a stopper of the sample holding portion 5. When suspending or dissolving the collected sample, the sample storage section 5 is filled with the liquid to be used for the sample in advance, and after the lid 1 is tightened, the entire instrument is shaken. At this time, the sample-collecting rod 2 functions as a stirrer and is effective in completing suspension or dissolution. The suspension solution is opened by removing the lid or stopper from the tip 15 or by punching with a needle or scissors, and pressing the outer cylinder 16 with a finger to take out a required amount of solution.
