Next, one mode of using the pressing device of the mode shown in FIG. 1 will be described. FIG. 3 is a schematic cross-sectional view showing one embodiment of a sample collecting device (for example, a fecal test device) that is preferably used in combination with the pressing device of the present invention described above.
As shown in FIG. 3, the stool examination device, which is one mode of this sample collection device, has a container body 10, a lid 12, and a stool collection stick 14. The lid 12 is preferably made of an elastic material such as rubber, and is fitted into the opening at the upper end of the container body 10 to seal the container body.

A through hole 16 is provided in the vertical direction at a substantially central portion of the lid body 12. The inner diameter of the through hole 16 is substantially the same as or slightly smaller than the outer diameter of the fecal sampling stick (an aspect of the sampling portion) 14. The stool collection stick 14
Is detachably inserted into the through hole 16 and held therein.

In a preferred embodiment, the lid 12 is provided with a cavity 17 having an open upper end inside, and a stool collection stick extruding member (one embodiment of extruding member for sampling portion) 18 is fitted into the inside. Has been The push-out member 18 has a thumbtack-like shape having a head portion 18a and a foot portion 18b. The head portion 18a is inscribed in the upper portion of the cavity 17 and has a foot portion 18b.
Is inserted halfway through the through hole 16. In this usage mode, the upper end of the stool collection stick 14 is inserted partway through the through hole 16.

In a preferred embodiment, the lid body 12 has a shoulder portion 12a, and the lid body 12 has such a size that the shoulder portion 12a contacts the upper end portion of the container 10 when the lid body 12 is fitted into the container 10. have. The container body 10 is preferably made of a colored transparent material. As the color of the container body 10,
For example, green is preferable.

The outer diameter of the container body 10 is about 10 mm.
It is preferably about 15 mm to 15 mm, particularly about 13 mm, and the height is preferably about 50 mm to 100 mm, more preferably about 80 mm to 95 mm. This is significantly larger than the conventional stool inspection container, and with such a size, the identification label can be directly attached to the container, it is possible to prevent confusion of samples and the sample rack. It facilitates automation of handling / analysis.

Next, an aspect of a method of using the above-mentioned stool collecting device will be described. At the time of collecting stool, with the stool collection stick 14 inserted in the through hole 16 in the lid 12, the lid 12 is pinched with a finger to attach stool to the tip of the stool collection stick. After the stool collection, the lid 12 is fitted into the opening of the container body 10 with the collection stick 14 attached, and the lid is closed. The lid 12
However, when the sticking stick extruding member 18 is provided as shown in FIG. 3, the extruding member 18 is also provided with the lid 1 as shown in FIG.
The stool collection operation is performed in a state where the stool is inserted into the second cavity 17.
The stool collection stick 14 is accommodated in the container body 10 while floating in the air, and is transported in this state.

In the inspection facility, first, the stick is inserted into the through hole 16 from above and pushed downward to detach the fecal sampling stick 14 from the lid 12 and drop it into the container body 10. When the stool collection stick pushing member 18 is provided, this operation can be easily performed by pushing the head portion 18a of the pushing member 18 downward.

At the time of this pressing operation, it is preferable to use the pressing device of this embodiment shown in FIG. 1 because such pressing operation can be simultaneously performed on a large number of containers.

Next, the lid 12 is removed from the container body 10. After opening the lid 12, the sample can be analyzed by injecting a buffer solution or the like into the container body 10 as in the conventional case. If the container body 10 has the preferred dimensions described above,
A plurality of the container main bodies 10 are attached to a sample rack (sample stand) 2
By setting it up to 0 (see FIG. 1), it becomes extremely easy to perform automatic dispensing to an analysis tray or the like and mass processing by mechanization.

According to the study of the present inventor, the pressing force when the lid 12 is pressed by the rod-shaped body 4 as described above is in consideration of the rapid pressing and the balance of the strength of the pressing device and the like. 500g ~ 3kg weight per one (more 1kg ~ 2
It is preferably about kg weight).

From the point of surely pressing the plurality of lids 12 described above, for example, as shown in FIG. 4, the head portion 18a of the pushing member 18 in the lid 12 is provided with a taper portion 18c, and
A protrusion 4a may be provided substantially at the center of the rod-shaped body 4 erected on the pressing plate 3 so that the center of the rod-shaped body 4 reliably presses the center of the pushing member 18 (direction b).

In the embodiment of FIG. 1 described in detail above, the manual lever 8 and the cam 7 are used as the driving means of the pressing plate 3, but other manual, as long as the above-mentioned predetermined pressing force can be generated, Of course, mechanical, electrical, or magnetic drive means may be used.

FIG. 5 thus shows another driving means (manual).
It is a schematic side view (partial cross section) which shows the pressing device of this invention at the time of using. In FIG. 5, for simplification,
Only one pair of the rod-shaped body 4 and the container 10 and the like are shown and the others are omitted. FIG. 6 is a stylized plan cross-sectional view of the pressing device taken along line BB in FIG. 5 (a view from below in FIG. 5).

Referring to FIGS. 5 and 6, in this embodiment, the L-shaped member 9, the cam 7 and the lever 8 of FIG.
Instead of the upper plate 19 fixed to the support 2,
A lever 8a rotatably arranged with respect to the lever 8a and a bolt 21 fixed to the lever 8a are provided. Figure 5
In addition, a nut 22 screwed to the bolt 21 is arranged, the pressing plate 3 is fixed to the nut 22, and is rotatably arranged with respect to the bolt 21. Therefore, when the lever 8a is rotated in a predetermined direction, the bolt 21 fixed to the lever 8a also rotates at the same time, so that the bolt 21 and the nut 22 fixed to the pressing plate 3 are rotated.
The pressing plate 3 is driven downward (against the urging force of the spring 5) based on the screw engagement with the rod-shaped body 4 in the same manner as in the embodiment of FIG.
As a result, at least a part of the lid 12 attached to the container body 10 is pressed, and the stick 14 falls into the container body 10.

In the embodiment of FIG. 5, as shown in FIG. 6, the rod-shaped body 4 is provided with a plurality of penetrating holes provided at positions corresponding to the rod-shaped body 4 so as to pass through the substantially central portion thereof. A perforated plate 23 having a hole 23a is arranged, and the spring 5 is arranged between the perforated plate 23 and the pressing plate 3. The perforated plate 23 is fixed to the column 2. Providing such a perforated plate 23 means that the perforated plate 23 is a rod-shaped body 4.
It is preferable in that it has a function as a guide and a function of preventing damage to the container 10.

[0029]

As described above, according to the present invention, there is provided a pressing device capable of simply and quickly disposing a measurement sample in a bottomed tube for measurement.

If the pressing device of the present invention is used, in particular, at least a part of the plurality of lid-shaped members mounted on the opening side of the bottomed tubes are simultaneously pressed so that they can be detachably attached to the lid-shaped members. It is possible to efficiently drop the inserted stick-shaped member into the bottomed tube.
