  Then, the stool specimen container 12 is lowered by lowering the dilution head part 20, and the container body part 12b is clamped by the container body part holding member 24 (see FIGS. 6 and 7B). In the sandwiched state, the lid 12c is separated from the container body 12b by raising the lid holding member 18 while rotating it. At that time, a so-called semi-separated state is used instead of complete separation so as not to hinder liquid dripping during movement.

  Next, the dilution head unit 20 is moved to a predetermined position on the dilution plate 14 by the first movement control means 26 and the second movement control means 28. After the movement, the lid 12c is completely separated from the container body 12b by raising the dilution head 20. Then, the container body 12b is moved by retracting the container body holding member 24 by the holding mechanism 78 and the lid 12c is lowered, so that the sample rod 12k to which the stool sample adheres is diluted in the corresponding dilution hole 14h. Immerse in the liquid. Then, the specimen bar 12k is moved up and down 2-3 times and then raised. As a result, a diluted specimen (dilution completion liquid) obtained by diluting the specimen in the stool specimen container 12 is accommodated in the dilution hole 14h.

  Further, the container body holding member 24 is advanced by the holding mechanism 78 to reach a position directly below the lid 12c, and the lid 12c is lowered while being rotated, so that the lid 12c is attached to the container body 12b and the lid is covered. To.

  Thereafter, the holding member 24t is moved forward to release the holding of the container body 12b, and the dilution head unit 20 is moved to the stool sample container storage port 118 corresponding to each sample rack 13, so that the stool sample container 12 is put into the storage port 118.

  Further, the aggregation head portion 34 is pivotally moved to the disposal position of the chip nozzle 32 and discarded by removing the chip nozzle 32 (see FIG. 8B). Then, unused chip nozzles 32 are attached to the aggregation head portion 34, and the diluted nozzle 14 is inserted into the chip nozzle 32 through the chip nozzle outer opening 114e into the 50 dilution holes 14h arranged in the outer dilution plate 14e. And place it in another unused aggregation tube 30. The same is done for the other set of dilution plates 14. Note that the suction from the tip nozzle outer opening 114e may be performed earlier than the tip nozzle inner opening 114i, and the sucking order is not particularly limited.

  Thereafter, each aggregation tube 30 (four aggregation tubes) is sent to the inspection process. At this time, if it is negative that no bacteria are detected, it is determined that no bacteria are present in the specimens in the plurality (50) of stool specimen containers 12 corresponding to the aggregation tube 30, and the test for 50 persons is completed. It becomes. On the other hand, if the bacteria are detected positive, it is determined that the bacteria are present in at least one of the plurality (50) of stool specimen containers 12 corresponding to the aggregation tube 30, and the next step is as follows. The specimens in the plurality of stool specimen containers 12 introduced into the storage port 118 are re-inspected, for example, in several times.

  As a result, the inspection of a large number of stool specimens can be completed efficiently, and a petri dish containing an agar medium can be dispensed with. Further, if the dilution plate 14 is newly replaced, it is possible to quickly cope with the next inspection and, for example, when the detection target is a norovirus, an Eppendorf tube (a stool with a lid connected to the container body) is used. A dilution plate having a shape corresponding to the (sample container) can be used.
