【Example】

 Hereinafter, the present invention will be clarified by explaining a fecal sampling device according to an embodiment of the present invention with reference to the drawings.

First Embodiment FIGS. 1 (a) and 1 (b) are a cross-sectional view and a perspective view for explaining a stool collection device according to a first embodiment of the present invention, respectively.

The stool collection device 1 has a stool collection device body 2 which is substantially rod-shaped as a whole, and an excess stool removal member 4 which is connected to the stool collection device body 2 by means of a ridge 3. The stool collection device body 2 is made of a material having an appropriate shape-retaining property such as a synthetic resin, and has a substantially rod-like shape as a whole. A recess 2b is formed on the outer surface near the lower end 2a of the stool collection device body 2. The recess 2b is provided to quantitatively store the collected fecal sample. In this embodiment, the concave portion 2b is formed so as to have a half-moon shape in cross section, but the concave portion 2b is formed by forming a square groove or by forming a hole having an appropriate shape. It may be configured. Also, a plurality of recesses 2b may be formed.

A flange portion 2c is formed on the upper end side of the stool collection device body 2. The flange portion 2c is provided to fix one end of the spring 3. Further, the spring 3 is composed of a pressing spring, and normally urges the surplus feces removing member 4 toward the lower end 2a side of the feces collecting instrument body 1. Instead of the spring 3, the surplus feces removing member 4 may be biased toward the lower end 2a by biasing means made of an elastic material such as rubber.

The surplus feces removing member 4 is made of, for example, a synthetic resin, and as shown in the figure, the inner surface 4 a thereof has a shape conforming to the side surface of the feces collecting instrument body 2. Further, the excess stool removing member 4 has a claw 4b extending in the same direction as the body of the stool collecting device on the upper end side, and is attached by the claw 4b so as not to fall off laterally from the body 2 of the stool collecting device. Therefore, the excess stool removing member 4 is configured to be slidable in the length direction of the stool collection instrument main body 2 while the inner surface 4a is in contact with the outer surface of the stool collection instrument main body 2.

In use, as shown in FIG. 2 (a), the surplus feces removing member 4 is slid against the upper end side of the feces collecting tool body 1 against the urging force of the pressing spring 3 with a finger to form the recess 2b. Expose. In this state, the stool sample body 2 is pierced into the stool sample, and the stool sample 5 is sampled on the recess 2b as illustrated. Then, the finger is removed from the excess stool removal member 4, and the excess stool removal member 4 is slid to the lower end 2a side by the urging force of the spring 3. As a result, the excess stool sample 5a rising on the recess 2b is removed by the excess stool removal member 4 and dropped downward from the tip 4c of the excess stool removal member 4 (see FIG. 2 (b)).

Therefore, it is possible to reliably collect the stool sample 5b in an amount corresponding to the volume of the recess 2b, and it is not necessary to wipe the stool collection device with paper or cloth when removing the surplus stool 5a. When dipping the collected stool sample 5b in a liquid for suspending a stool sample prior to the inspection, the surplus stool removing member 4 is pulled up again against the biasing force of the pressing spring 3 to expose the recess 2b, It may be immersed in the above liquid.

In the present embodiment, as shown in the drawing, an inclined surface 4 d is formed on the tip 4 c side of the surplus feces removing member 4, so that the tip 4 c has a knife-edge shape. Therefore, the surplus stool that has risen above the recess 2b is more reliably removed. However, the tip side of the surplus feces removing member 4 does not have to have the inclined surface 4d as described above, and even in that case, the surplus feces sample bulged on the recess 2b is removed by the surplus feces sample. It can be removed by the member 4.

FIG. 3 is a perspective view for explaining the stool collection device according to the second embodiment. The stool collection tool body 12 and the excess stool removal member 14 in the stool collection tool 11 of the second embodiment are configured similarly to the stool collection tool body 2 and the excess stool removal member 4 of the first embodiment. Therefore, the corresponding portions will be denoted by the corresponding reference numerals, and the description thereof will be omitted.

The feature of this embodiment is that the spring 13 is composed of a tension spring, and as shown in FIG. 3, the surplus feces removing member 14 is always attached to the flange 12c of the feces collecting tool body 12 as shown in FIG. It is biased to the side, thereby exposing the recess 12b. The other points are similar to those of the first embodiment.

In use, as shown in FIG. 4 (a), the stool collection device body 12 with the recess 12 b exposed is pierced into the feces to collect the stool sample 17 in the recess 12 b. Then, the surplus feces removing member 14 is slid to the lower end 12a side against the biasing force of the spring 13, and the surplus feces sample adhered on the recess 12b is scraped off by the surplus feces removing member 14 to the tip side. Let it fall. In this way, the amount of feces according to the volume of the recess 12b is reliably collected. Also in this embodiment, it is not necessary to wipe the stool collection device with paper or cloth when removing the excess stool.

After removing the excess stool, the excess stool removing member 14 is returned to the initial position by releasing the finger from the excess stool removing member 14 and releasing the finger, and by the biasing force of the spring 13. As a result, the stool sample collected in the recess 12b is exposed. In this state, the collected stool sample can be suspended by dipping the stool sample body 12 in a liquid for suspending the stool sample.

FIGS. 5A and 5B are cross-sectional views for explaining the stool collection device according to the third embodiment. In the stool collection tool 21 of the third embodiment, a concave portion 22b is formed on the outer side surface near the lower end 22a of the substantially rod-shaped stool collection tool body 22. Up to this point, the construction is similar to that of the stool collection instrument main bodies 2 and 12 of the first and second embodiments. The difference is that a knob 22c having a larger diameter than the main body portion of the stool collection device body 22 is integrally provided on the upper end side of the stool collection device body 22.

A pressing spring 23 is wound around the body portion of the toilet bowl body 22 below the knob 22c of the toilet bowl body 22. Furthermore, the upper end of the spring 23 is fixed to the lower surface of the knob 22c. A cylindrical surplus feces removing member 24 having a diameter larger than that of the wound portion of the spring 23 is connected to the lower end of the spring 23. Therefore, the excess feces removing member 24 is connected to the knob 22c by the spring 23. However, the excess stool removal member 24 and the stool collection device main body 22 may not be connected, and therefore the spring 23 may not be fixed to the lower surface of the knob 22c and the upper surface of the excess stool removal member 24.

The surplus feces removing member 24 is a cylindrical member and is made of a material having an appropriate shape-retaining property such as synthetic resin. A state in which the inner diameter of the through hole 24a extending in the length direction of the surplus feces removing member 24 is configured to be substantially equal to the outer diameter of the main body portion of the stool collection device main body 22 and is urged downward by the spring 23. In the above, the excess feces removing member 24 has a length capable of covering the recess 22b.

In use, the surplus feces removing member 24 is held by hand, and the knob 22c is pressed downward with a finger. As a result, as shown in FIG. 5B, the spring 23 is pressed and the recess 22b is exposed. In this state, the stool sample body 22 is pierced into the stool sample, and the stool sample is collected in the recess 22b. Then, while holding the surplus feces removing member 24 by hand, the force applied to the knob 22c is released, and the restoring force of the spring 23 causes the main body 22 of the fecal sampling device to be in the state shown in FIG. 5 (a). Return to. As a result, surplus stool attached to the recess 22b is scraped off by the lower surface 24a of the surplus stool removing member 24, and an amount of stool sample corresponding to the shape of the recess 22b is collected in the recess 22b.

When suspending the collected stool sample in the stool suspension, the knob 22a is pressed again to expose the recess 22b, and the stool sample collected in the recess 22b is immersed in the stool suspension. Good.
