Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a cell storage container for storing cells scraped from an affected area with a brush and removed from the brush.

(Prior art) In so-called abrasion cytology, in which cells are scraped directly from a lesion using a brush called an abrasion brush, and the cells are examined and diagnosed, a brush called an abrasion brush is used to scrape off cells attached to the brush. A cell storage container equipped with the following methods is used.

A scraping brush insertion hole is provided in the lid of the container.The tip of the brush with cells attached is inserted into the container through the hole, and the brush is pulled out from the hole while pressing the brush tip against the edge of the hole. This will scrape off any cells that have adhered to the brush into the container.

(Problem to be solved) The brush insertion hole is opened in the shape of a slit, and the hole is formed with a uniform width smaller than the diameter of the brush part of the abrasion brush, so when the brush is inserted into the hole, the cells are attached to the edge of the hole. There was a problem that the cells were scraped off and the amount of cells collected into the container was reduced.

(Purpose of the present invention) The purpose of the present invention is to provide a cell storage container with high cell recovery efficiency.

(Means for solving the problem) In order to achieve the above object, the cell storage container of the present invention has a scraping brush insertion hole 4 formed in the lid body 2.
, a narrow portion 42 through which the shaft portion 51 of the brush 5 can barely pass, and a wide portion 41 having a width approximately corresponding to the diameter of the brush portion 52 are continuous.

(Operation and Effect) Insert the brush 5 with cells attached into the container from the wide part 41 of the brush insertion hole 4 of the lid 2, slide the tip of the brush to the narrow part 42 side of the insertion hole 4, and then insert the brush 5 into the container. bring out.

When inserting the brush 5 into the container, the brush 5 is passed through the wide portion 41 of the insertion hole 4, so that only a small amount of cells attached to the brush 5 are scraped off by the upper edge of the insertion hole 4.

When removing the brush 5, use the narrow part 4 of the insertion hole 4.
2, cells adhering to the brush 5 are effectively scraped off into the container by the lower edge of the insertion hole 4, and the recovery rate of cells adhering to the brush 5 is improved.

(Example) As shown in FIG. 2, the scrubbing brush 5 has a flexible shaft 51 with a diameter of about 0.3 mm formed by twisting metal wires together.
It has a brush part 52 made of synthetic resin at the tip thereof, and the diameter of the brush part 52 is about 2 mm.

The cell storage container is composed of a container body 1, a lid 2 covering the main body 1, and an outer lid 3 covering the lid 2, each of which is made of synthetic resin.

The container body 1 is a transparent cylindrical body with a bottom having a vertical length of about 32 mm, an outer diameter of 12 mm, and a wall thickness of about 1 mm.

The container body 1 has a thread 12 formed on the inner surface of the opening,
The bottom part 11 has a raised bottom, and the bottom part 11 is formed in a mortar shape with a lower central part.

The lid body 2 has a large-diameter cylindrical portion 21 with an open top surface at the top and a small-diameter cylindrical portion 22 with a bottom at the bottom. A thread 24 is formed, and a thread 23 into which the outer lid 3 is screwed is formed on the inner surface of the large diameter cylindrical portion 21.

A brush insertion hole 4 is provided at the bottom of the lid 2.

As shown in FIG. 3, the insertion hole 4 has an isosceles triangular shape extending in the diameter direction of the bottom surface.
The maximum width of is slightly larger than the outer diameter of the brush portion 52 of the scrubbing brush 5.

As shown in FIG. 1, the top surface of the bottom of the lid 2 is sloped low on the wide side of the insertion hole 4, and sloped low on the edge side of the hole.

A through hole 25 is formed in the circumferential surface of the small diameter portion of the lid body 2 slightly above the bottom portion.

The outer lid 3 has a threaded cylinder 31 at the bottom that is screwed into the lid body 2.
is provided protrudingly, the upper part becomes a knob part 32, and the cover plate 33
is blocking the inside.

A lid 2 and an outer lid 3 are screwed onto the container main body 1, and a cell fixative such as a sputum preservation fixative is previously filled in the main body to the extent that it reaches the top of the lid 2.
Prevent the collected cells from drying out.

Then, the outer lid 3 is removed, and the brush 5 with the cells attached thereto is inserted into the container through the wide part 41 of the disassemble insertion hole 4 of the lid 2.

Since the bottom of the lid body 2 is sloped low on the wide side of the insertion hole 4, the tip of the brush 5 is guided into the insertion hole 4 along the slope.

After sliding the brush 5 toward the narrow part 42 side of the insertion hole 4, the brush 5 is pulled out.

As mentioned above, when inserting the brush 5 into the container, it is passed through the wide part 41 of the insertion hole 4 of the lid 2,
Since the wide portion 41 has a width approximately corresponding to the brush portion 52, only a small amount of cells attached to the brush 5 are scraped off by the upper edge of the hole 4.

When removing the brush 5, the cells that have adhered to the brush 5 are effectively scraped off into the container by the lower edge of the insertion hole 4 because they are passed through the narrow part 42 of the insertion hole 4. The recovery rate of attached cells is improved.

If the through hole 25 is provided in the lower circumferential surface of the lid body 2 as in the embodiment, when the brush 5 is inserted into the insertion hole 4, a portion of the collected cells will be removed at the upper edge of the insertion hole 4. Even if the cells are scraped off, the cells float in the cell fixative and move into the container through the through hole 25, thereby increasing the recovery rate of the cells.

4 to 6 show other embodiments of the brush insertion hole 4 provided in the lid body 2, and in FIG. 4, the round hole side from both sides on the diameter line with respect to the central round hole 43 is shown. The brush insertion hole 4 is a series of gradually narrowing holes 44, 44. The brush insertion hole 4 shown in FIG. The brush insertion hole 4 has a plurality of narrow notches 46 at the edge of the hole 45.

The drawings and the description of the above-mentioned embodiments are for explaining the present invention, and are not intended to limit or reduce the scope of the invention described in the claims of the utility model registration.
