At least one side of the upper end of the base 6 is provided with a limiting part 11 extending upward, when the slide 7 is placed on the base 6, the side wall of the slide 7 needs to abut against the limiting part 11 on the side thereof, and a soft rubber pad 10 is arranged at the cup opening of the sampling cup 1, which is an annular structure matched with the cup opening of the sampling cup 1, and the soft rubber pad 10 can be made of a material with certain elasticity such as silicone rubber or rubber.

[0023] Specific use method: first, the examinee removes the cup cover 2 from the sampling cup 1, and then spits sputum into the sampling cup 1, at this time the cup opening of the sampling cup 1 faces upward. Then, the examinee hands over the sampling cup 1 to the detection personnel, who adds digestive solution, inactivation solution or the like into the sampling cup 1. Then the detection personnel screws the cup cover 2 tightly on the sampling cup 1 from top to bottom, so that the soft rubber pad 10 tightly contacts with the slide 7, and the base sheet 8 is located inside the soft rubber pad 10.

[0024] The detection personnel checks whether the sampling cup 1 is tightly covered, and then performs marking, collection or the like. The detection personnel brings the collected sampling cup 1 back to the detection center, and performs centrifugation in a centrifugal device in the detection center. Before centrifugation, the detection personnel places the sampling cup 1 on a tooling 12 with the cup opening facing downward, a groove matched with the base 6 is arranged on the tooling 12, and then the tooling 12 is placed on the centrifugal device, which can be a horizontal centrifuge. During centrifugation, the bacteria, cells or the like in the specimen are adsorbed by the base sheet 8.

After the above actions are completed, the examinee hands over the sampling cup 1 to the detection personnel.

[0029] The detection personnel checks whether the sampling cup 1 is tightly covered, and then marks, collects and the like. The detection personnel brings the collected sampling cup 1 back to the detection center, and performs centrifugation in the centrifugal equipment of the detection center. Before centrifugation, the detection personnel places the sampling cup 1 on the tooling 12 with the cup opening facing downward, the tooling 12 is provided with a groove matched with the base 6, and then places the tooling 12 on the centrifugal equipment, which can be a horizontal centrifuge. During centrifugation, the pretreatment liquid in the inner cup 3 pushes open the sealing cover 4 under the action of centrifugal force or the like, so as to treat the specimen.
