Since there are many types of capacity, it is troublesome to select a container according to the capacity of the sample, and there are some that can not be applied to the centrifuge.In that case, it is necessary to transfer to a centrifuge container for the sample, but the operation is complicated. Not only that, there are cases where the sample may spill or stick to the fingers, and because the length of the body (4) is short, it is difficult to stand on the Spitz table. The bottom of the body (4) has a round bottom. Therefore, it is difficult to form a buffy coat even after centrifugation, which makes it difficult to collect nucleated cells, and because the cap (6) is a push-in type, the sample may scatter when the cap is attached or removed, and the fingers may become dirty. There were problems such as being hygienic. In particular, spilling of a sample or sticking to a finger is a serious problem because it may cause infection with hepatitis B, AIDS and the like.

衛生的である。The size of the container of the present invention is selected from the following range from the most efficient applicability to the conventional cytological liquid sample, buffy coat forming property, workability, and functionality that can be applied to a conventional centrifuge; ) Cylindrical head outer diameter D 1 = 26 to 33 mm Length L 1 = 26 to 33 mm (B) Tapered neck length L 2 = 6 to 10 mm (C) Cylindrical body outer diameter D 2 , D 3 = 13 to 17 mm Length L 3 = 50 to 70 mm (D) Tapered bottom length L 4 = 22 to 28 mm Total volume: 15 to 30 ml The cell sample container for liquid samples with the above configuration is a normal centrifuge as it is after sample collection. Can be used. The specimen forms a sediment on the tapered bottom portion (16) by centrifugation, and forms a buffy coat on the sediment. The buffy coat is collected, smeared on a slide glass, stained, and a cover glass is placed thereon to obtain a sample of nucleated cells. Container body (1
In 1), since the outer diameters D 2 and D 3 of the cylindrical body (15) are formed within the above ranges, respectively, it can be applied to a normal centrifuge as it is, and the sample can be transferred to another centrifuge container. No need to change. Also, the total length L 3 + L 4 of the cylindrical body (15) and the tapered bottom (16) is 72 to 98 mm, so
It can stand on a spitz table and is easy to handle and transport. Further, if the inside of the tapered bottom portion (16) is formed from the tapered hole (21) and the parallel hole (22) as shown in the figure, it is easier to form the buffy coat after centrifugation and collect the nucleated cells. Furthermore, since the cap (12) is a screw type, there is no scattering of specimens and stains on fingers when attaching and detaching,
It is hygienic.

効率的に採取することができる。By the way, according to the results of the actual investigation of the liquid specimen in the cytodiagnosis test conducted by the inventor, 69% of the investigations were 20 ml or less and 86% were 40 ml or less. Therefore, the cell collection container for liquid specimens of the present invention can be set to 15 to 30 ml by setting the volume to 20 ml, since one can handle 69% of cases and two can support 86% of cases. Almost if
You can see that it can handle 100%. Also, 56% of the surveyed specimens were able to centrifuge sediment into the parallel holes (22), and 95% of specimens were able to centrifuge into the parallel holes (22) with tapered holes (21). It was Therefore, even if the sediment contains many red blood cells, a buffy coat can be easily formed and nucleated cells can be efficiently collected.
