Abstract

PURPOSE:To simplify a series of operations for the pickup of the specimen of the secretion from a vagina and cervical dust, the dissolution of the specimen after the pickup of the specimen and the dropping of the dissolution liquid by providing a plugs at the head part of a tubular container comprising flexible synthetic resin so that the plug can be attached and removed, and tightly sealing the tip of the bill pipe at the lower part of container with the synthetic resin. CONSTITUTION:A tubular container 3 comprises elastic polyethylene. A plug 4 is provided at the head part. The tip of a bill pipe 5 at the lower part of the container 3 is tightly sealed with the polyethylene. The tightly sealing point is formed of a weak part 6. A specimen pickup tool 1 is the rod-shaped body. A secretion attaching part 7 is provided at one end, and the other end is connected to the inner surface of the plug 4. After the specimen is picked up into the secretion attaching part 7, the pickup tool 1 is dipped into dissolution liquid 2 in the container 3. At the same time, the head part of the container 3 is tightly plugged with the plug 4 by screwing. When the specimen is dissolved and the measurement is performed, the weak part 6 at the lower part of the container 3 is twisted off, and the bill pipe 5 is opened. When the container 3 is pushed with the hand and the dissolution liquid 2 is dropped into a test tube, the role of a syringe can be performed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sample collecting device used for measuring the contents of vaginal and cervical secretions, that is, viral antigens, antibodies, proteins, enzymes and the like.

[0002]

2. Description of the Related Art When measuring the content of vaginal or cervical canal secretions, it is necessary to quantitatively collect the secretions and drop them into a predetermined cassette or the like. However, since this secretion is mucous, it is difficult to collect a fixed amount of it, and when it is applied to a test strip for chromatographic analysis, the sample is quickly absorbed and absorbed.
Do not deploy. For this reason, the secretion is collected with a cotton swab, and a certain amount of the solution is dropped in the test tube to elute the solution.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention Regarding the method of collecting secretions, a method of directly collecting with a pipette or the like, and a collecting tool such as a cotton swab as disclosed in US Pat. No. 3,776,219 are disclosed. However, in all cases, it was necessary to dissolve the collected secretions and then collect the lysate with a dropper for inspection or measurement. As described above, members for the sample collecting tool, the dissolution container, the dropper, and the test tube were required.

An object of the present invention is to provide an integrated sample collecting tool, dissolution container and dropper.

SUMMARY OF THE INVENTION The present invention is a cylindrical container for containing a sample collecting tool and a solution, wherein the material of the cylindrical container is a synthetic resin having elasticity, and the cylindrical container is transparent. There is a detachable fitting plug attached to the head of the, the lower part of the cylindrical container is the beak tube, the tip of the beak tube is sealed with synthetic resin, the sealing point is formed by the fragile part, the specimen The gist of a sample collecting tool is characterized in that the collecting tool is a rod-shaped body, and a secretion adhering portion is provided at one end and the other end is connected to the inner surface of the stopper.

In the present invention, the sample collecting tool is a rod-shaped body having a secretory substance attachment portion at one end and a plug body at the other end. Here, the secretory substance-attached portion is required to have physical properties such that it is soft to the touch, flexible, and elastic. The material may be made of water-absorbent material such as cotton, gauze, non-woven fabric, sponge-like regenerated cellulose, etc., but if the secretion is highly viscous, it is made of hydrophobic material such as rubber or plastic, such as polyurethane foam. It does not affect the collection of secretions. Examples of secretions include vaginal and cervical secretions and pharyngeal swab.

The rod of the sample collecting tool has an outer diameter of 2 to 4 mm,
Polymer materials are preferable in terms of lightness, durability, flexibility, etc.
The means for connecting the sample collecting tool to the stopper is not particularly limited, such as using an adhesive or physically inserting it. The size of the whole sample collecting tool is selected so that the secretion-attached part is immersed in the solution in the sample collecting device, but the length is 5 to 5
It is about 17 cm.

In the present invention, a phosphate buffer or the like is used as the dissolving solution. The amount of the solution needs to be enough to immerse the secretory substance-attached part, but it is not preferable to exceed half the total volume of the cylindrical container.

In the present invention, the cylindrical container is made of a synthetic resin having elasticity because the function of a dropper is required at the time of use, and the inside of the cylindrical container is transparent for confirming the positions of the sample collecting tool and the solution. It is necessary to be able to do it. Since the sample container and the dissolution liquid must be stored in the cylindrical container, for example, the inner diameter is 5 to 15 mm and the length is 7 to 2
It is 0 cm.

In the present invention, the stopper attached to the sample collecting tool is for substantially preventing gas and liquid from leaking inside the cylindrical container. Therefore, the plug is detachably attached and fitted at the head of the cylindrical container. If it is satisfied that gas and liquid do not leak, for example, screwing may be used instead of fitting.

In the present invention, the beak tube in the lower part of the cylindrical container is such that the beak tube opens when the fragile portion is screwed or is torn off, and the solution in the cylindrical container does not fall due to the effect of surface tension. Required to have inner diameter.

[0012]

The device for collecting a specimen of the present invention is a container for dissolving and dropping the secretion after collecting the secretion when measuring the substance in the secretion of the vagina and cervix.

A collecting tool such as a cotton swab from which a sample is collected is put into the container from the head of the collecting tool to form a stopper, and the sample adhered to the cotton swab of the collecting tool is dissolved with a dissolving solution, and then the fragile portion is twisted during inspection. Then, the solution of the sample is dropped from the opening of the beak tube while pulling off and pressing the cylindrical container from the outside. According to the present invention, a storage container for a solution, a test tube for dissolution, and a dropper for dropping are integrated to simplify a series of operations for dissolution and dropping after sample collection.

[0014]

EFFECT OF THE INVENTION Since the sample collecting device of the present invention has the above-mentioned structure, it can collect samples of secretions from the vagina and cervix.
It is a container that can easily perform a series of operations of dissolving a sample and dropping a solution after the sample is collected. In addition, the container can be inexpensively supplied by such integration.

FIG. 1 is a cross-sectional view of the sample collecting device of the present invention as viewed in the longitudinal direction, and FIG. 2 is a cross-sectional view of the sample collecting device of the present invention as viewed in the longitudinal direction for explaining the dissolution droplets. .

FIG. 1 shows the time when the sample is dissolved. One end of the sample collecting tool 1 is connected to the stopper 4 with an adhesive. After collecting the sample in the secretory substance attaching part 7, the sample collecting tool 1 is immersed in the solution 2 in the cylindrical container 3. At the same time, the head of the cylindrical container 3 is tightly plugged with the plug 4 by screwing. When the sample is dissolved and ready for measurement, twist the fragile portion 6 at the bottom of the cylindrical container 3 completely,
