In other embodiments, filter screen 32 may be provided as a separate component.

Through setting up filter assembly 30, can utilize filter assembly 30 to filter the particulate matter that is greater than the filtration diameter in the excrement and urine, after the residue of large granule was filtered through this structure to the sample, can improve the save effect of sample in the preservation liquid to a certain extent on the one hand, on the other hand can avoid when follow-up detection sample, large granule thing jam pipetting gun head, the sample of influence pipetting gun or pipetting instrument.

In order to seal the collection assembly, the blending part 20 of the collection assembly further comprises a protective plug 25, and the protective plug 25 is clamped in the blending pipe 22 and is arranged close to the outlet of the blending pipe 22. After the user has collected the sample with collection piece 10, because the export of mixing pipe 22 is provided with protection stopper 25, and the import of mixing pipe 22 is provided with gathers skull 14, mixing pipe 22 can form seal structure, and the mixed liquid can not leak from gathering the subassembly. Specifically, the protective plug 25 has a second blocking position and a second opening position which are opposite to each other, and when the protective plug 25 is located at the second blocking position, the protective plug 25 blocks the outlet of the mixing pipe 22. Through being provided with boss 33 in filter tube 31, make boss 33 correspond protection stopper 25 setting, because the position between filter tube 31 and the mixing pipe 22 is adjustable, through adjusting the relative position between filter tube 31 and the mixing pipe 22, can utilize boss 33 drive protection stopper 25 to remove, when protection stopper 25 moved to the second open position by the second shutoff position, mixing pipe 22 communicated with filter tube 31. And, through setting up protection stopper 25, the testing personnel is at the in-process of connecting the filter tube, and the mixing pipe can keep vertical direction to change, and liquid does not spill.

Specifically, after the protective plug 25 is pushed into the blending pipe, due to the existence of the boss 33, even if centrifugal force is applied to accelerate the filtering of the sample, the protective plug cannot block the lower pipe opening or the filter screen, so that the sample is blocked to flow into the filter pipe.

Wherein, can set up the push-and-pull structure between filter tube 31 and mixing pipe 22, utilize the adjustable relative position between filter tube 31 and the mixing pipe 22 of push-and-pull structure, perhaps, can be with filter tube 31 and mixing pipe 22 threaded connection, through making filter tube 31 rotate relative mixing pipe 22, can adjust the relative position between filter tube 31 and the mixing pipe 22. In this embodiment, the filtering pipe 31 is screwed to the kneading pipe 22.

In order to collect the filtered liquid, the collecting device further comprises a collecting pipe 40, the collecting pipe 40 is detachably connected with the filtering assembly 30, and the collecting pipe 40 is used for collecting the liquid filtered by the filtering assembly 30. Wherein the collecting pipe 40 is detachably connected with the second end of the filtering pipe 31. Specifically, the collecting pipe 40 is screwed to the second end of the filtering pipe 31.

Wherein, one-dimensional codes or two-dimensional codes can be printed on the bottom and the side of the filter tube 31 and/or the rear collection tube 40 for tracking and recording the sample information. According to needs, the tube cover of the collecting tube 40 can be a groove hexagon socket, and the tube bottom can be hexagonal or hexagonal clamping lines, so that the cover and the tube bottom can be fixed by a corresponding cover opening instrument and realize automatic cover opening of the instrument, and the tube bottom is conical, so that the biological sample can be conveniently treated and taken.
