BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a centrifuge tube used for clinical examination.

[0002]

2. Description of the Related Art Conventionally, when a liquid sample sediment is smeared on a slide glass or the like to perform a clinical test such as a cytological test or a bacterial test, a sample for clinical test as shown in FIG. 3 is used. A sinking tube and spoid were used.

In FIG. 3, reference numeral 20 is a centrifuge tube for clinical examination set in a centrifuge. The centrifuge tube 20 is a substantially cylindrical container body 21 made of transparent polyethylene.
And a lid 22 attached to a mouth portion 23 of the container body 21. Reference numeral 10 is a liquid sample contained in the container, and 11 is a sediment. And the container body 2
The bottom 24 of No. 1 is formed in a substantially conical shape so that the sediment 11 is deposited.

In order to smear the sediment 11 from the specimen 10 onto the slide glass for smearing using the centrifuge tube 20, the specimen 10 is first collected in the centrifuge tube 20 and centrifuged, and then the separated specimen 10 is separated. After removing the supernatant liquid by suction with an aspirator from the mouth portion 23 of the container body 21 or by inverting the container body 21, the sediment 11 is collected from the mouth portion 23 with the spid 25 and slide glass It was dripped on top, and another slide glass was used to spread the sediment thinly.

[0005]

As described above, in this conventional centrifuge tube, in order to smear the sediment 11 on a slide glass or the like, first, the supernatant of the separated sample 10 is removed by some method and then the container The sediment 11 was collected from the mouth portion 23 with a spoid or the like, dropped on a slide glass, and the sediment 11 was thinly spread using another slide glass or the like, which was a troublesome work. . In particular, when the amount of the sediment 11 is small, much attention and time are required to smear the sediment 11 on a slide glass or the like using a spoid or the like.

Further, this centrifuge tube is often used for medical treatment, and in this case, the liquid separated as the specimen 10 is
It is discharged from the human body such as urine, and it is very unsanitary to inhale and discharge it with something like a spoid, so that mutual contamination does not occur,
There is a drawback in that it is necessary to change the spoid used for each specimen 10 each time or to wash each time.

The present invention has been made in consideration of the above points, and it is a clinical method in which the sediment of a separated sample for clinical examination can be applied to a slide glass hygienically and very easily. It is intended to provide a sediment smear container for inspection.

[0008]

Means for Solving the Problems That is, the present invention comprises a container main body for accommodating a liquid sample and a lid detachably attached to a mouth portion provided in the container main body. And the bottom of the lid is funnel-shaped, and further, a plurality of wart-shaped projections are provided on the bottom of the lid, and the sediment is guided to the bottom of the lid near the mouth of the container body. It is characterized by having a constricted neck.

[0009]

In the above-mentioned present invention, when the specimen is centrifuged by making the inner surface of the shoulder portion of the sediment smear container for clinical examination and the bottom surface of the lid into a funnel shape, the lid should be placed down, contrary to the conventional case. By centrifuging, sediment can be deposited on the funnel-shaped bottom formed on the lid.After centrifugation, remove the lid with the lid facing upwards, and slide the bottom on the slide glass. By rubbing the sample, it is possible not only to omit the supernatant removal work and to improve the sample preparation work such as no need for spoids, but also to facilitate the sample work of a sample with a small amount of sediment that was difficult to smear by the conventional method.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partial cross-sectional view of a sediment smearing container for clinical examination showing an embodiment of the present invention. In FIG. 1, reference numeral 1 is a sediment smearing container for clinical examination set in a centrifuge. This sediment smearing container 1 is composed of a container body 2 made of transparent polyethylene and a lid 3 made of soft rubber or synthetic resin and attached to an opening 2b of the container body 2. A sample 10 is contained in the container body 2.
Reference numeral 11 is a sediment of the sample 10.

Further, the lower end portion 2a of the container body 2 and the upper end portion 3a of the lid body 3 are shaped so as to fit in a conventional centrifuge so that they can be used in a general centrifuge and the container body 2
By setting the internal volume of 60 ml to 60 ml, which is six times that of an ordinary centrifuge tube, a sufficient amount of the sediment 11 for the test can be taken out even for a sample having a small amount of sediment.

When centrifuging using this sediment smear container 1, the sediment smear container 1 is set so that the lid body 3 faces downward, but the inner surface of the shoulder portion 4 of the container body 2 and the bottom surface 5 of the lid body 3 are Since it has a funnel shape, the sediment 11 is deposited on the bottom surface 5 of the lid 3. Also,
A slight constriction 8 is provided near the mouth of the container body 2 so that the sediment 11 is completely guided to the bottom surface 5 of the lid 3.

On the other hand, since the inner surface of the bottom portion 6 of the container body 2 is also formed in a funnel shape, the specimen 1 having an extremely large amount of sediment 11 is present.
When handling 0, centrifugation may be performed with the lid body 3 facing up as in the conventional case, and at this time, the sediment 11 is deposited around the lowermost portion 6a of the bottom portion 6. Further, the container body 2 is provided with scales 7 in both the forward and reverse directions so that the volume of the sample 10 in the container can be seen regardless of whether the lid 3 is on the top or the bottom.

The lid 3 has a bottom surface 5 as described above.
Is formed in a funnel shape having an inclination of about 45 °, and is shaped like a suction cup. Further, the corners 3b of the lid 3 are rounded so that the sediment smearing container 1 will not be displaced when it is set in the centrifuge so that the lid 3 is placed downward.

Even if the lid 3 is not screwed, if the angle (45 °) shown in the figure, the lid 3 is the mouth 2 of the container body 2.
Since the force pressed against b is much stronger than the force with which the lid 3 tries to come off, as a result of the experiment, liquid leakage does not occur even at 3000 rpm. However, the shape of the lid body 3 is not limited to this, and may be a funnel shape so that the sediment 11 is deposited on the bottom portion 5 of the lid body 3, and may be, for example, a screw type.

FIG. 2 is a perspective view showing a procedure for smearing the sediment 11 deposited on the bottom surface 5 of the lid 3 after centrifugation. In FIG. 2, reference numeral 12 is a slide glass on which a sample is placed for cytodiagnosis test, bacteria test, or the like.

The sediment 11 deposited on the bottom surface 5 of the lid body 3 after centrifugation can be separated from the specimen 10 by simply placing the lid body 3 on top, and the lid body 3 is removed from the container body 2. By pressing the suction cup-shaped bottom surface 5 against the slide glass 12, the whole amount of the sediment 11 can be smeared on the slide glass 12, the supernatant removal operation can be omitted, and a specimen can be prepared without the need for any spoid. You can

Further, since the portion on which the sediment 11 is deposited is formed in a suction cup shape, it becomes a flat surface only by lightly pressing it against the smeared surface of the slide glass 12 or the like. There are four 9s (see Fig. 1).

[0019]

As described above, the sediment smear container for clinical examination of the present invention has a funnel shape on the inner surface of the shoulder of the container body and the bottom surface of the lid, so that the specimen can be used for clinical examination. In the case of performing the centrifugal separation of, by performing the centrifugation with the lid body as the bottom contrary to the conventional method, it is possible to deposit the sediment on the funnel-shaped bottom surface formed in the lid body,
After centrifugation, the sediment accumulated on the lid can be separated simply by placing the lid on top, so the supernatant removal operation can be omitted,
Not only can the sample preparation work be improved by eliminating the need for sucking with a spoid, etc., but also the sample work of a sample with a small amount of sediment that was difficult to smear by the conventional method can be easily performed.
Also, since the neck is provided, it is possible to guide the sediment completely to the bottom surface of the lid without leaving it near the mouth,
This has the advantage that even a sample with a smaller amount of sediment can extract a sufficient amount of sediment for examination. Furthermore, it is necessary to press the lid against the smearing surface in order to smear the sediment accumulated on the bottom surface of the lid onto the slide glass, but since the wart-shaped protrusions are provided, this lid causes the slide glass to move. It also has the advantage that it can be moved easily by avoiding close contact with.

Therefore, by using the sediment smearing container for clinical examination of the present invention, the sediment centrifugally separated in the clinical examination can be collected and smeared very easily and hygienically.
