Description

Technical Field

[0001] The utility model relates to a collection and processing device, in particular to a feces collection and processing device. Background Art

[0002] In the POCT industry during feces detection, usually after collecting feces, it is necessary to dilute, mix evenly, remove feces residues, and sample before testing.

[0003] When the applicant was making this application, after retrieval, it was found that the Chinese patent disclosed "a feces collection and processing device" with the application number "CN201721059197.1". This patent mainly uses a single sampling structure. When this sampling device is used, its single sampling structure cannot filter impurities in feces, which may lead to errors during testing.

[0004] Therefore, we propose a collection and processing device for removing inhibitors in feces samples. Content of the Utility Model

[0005] The utility model provides a collection and processing device for removing inhibitors in feces samples. Before use, after putting the stainless steel screen on the inner surface of the filter tube, then put activated carbon and filter cotton into the filter tube in sequence. Finally, put the four columns of the pressing ring upward into the filter tube. After the filter material structure is placed in the filter tube structure, then put the filter tube structure into the sample collection tube filled with preservation liquid until the lower surface of the fixing seat contacts the upper surface of the sample collection tube. Finally, threadedly install the tube cap on the threaded annular surface at the upper end of the sample collection tube until the lower surface of the tube cap contacts the upper surface of the fixing port, and the preservation liquid seeps into the filter tube through the filter port. When in use, first put a spoonful of feces into the filter tube containing preservation liquid, tighten the tube cap, and then vortex and oscillate for five minutes to make the feces disperse evenly. Then put the collection and processing device into the centrifuge. At this time, under the action of centrifugal force, the feces in the sample filter tube pass through the filtration of the pressing ring, filter cotton, activated carbon and stainless steel screen, and the clear liquid will enter the collection tube through the filter port. Finally, discard the filter tube containing feces residues and keep the clear liquid in the collection tube, and take it out for inspection. The setting of the filter tube structure can enable the feces sample to obtain the final inspected sample during centrifugation, increasing the accuracy of experimental detection. The setting of the filter material structure is to be able to completely filter the impurities in feces and reduce experimental errors.
