[0002] A concentration system for enriching parasite eggs in herbivorous animal feces is to effectively collect, enrich and extract parasite eggs in fecal samples for disease diagnosis, research or treatment. Parasites are a type of organism that biologically depends on other organisms (called hosts) to survive and obtain nutrition from them. They can live inside or outside the host, sometimes causing harm to the host and causing diseases. Parasites can be transmitted in various ways, including food, water, air, contact infection and other routes. Some parasites can cause serious infectious diseases, such as malaria, schistosomiasis, scabies, etc. Therefore, it is very important to prevent and control parasites, including health education, environmental sanitation improvement, drug treatment and other measures.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a concentration system for enriching parasite eggs in herbivorous animal feces, comprising an upper chamber collecting tube and a sample chamber, the interior of the upper chamber collecting tube is fixedly connected with filter screen one, the interior of the upper chamber collecting tube is fixedly connected with filter screen two, the interior of the upper chamber collecting tube is fixedly connected with filter screen three, the bottom of the upper chamber collecting tube is threadedly connected with a lower chamber collecting tube, and the outside of the upper chamber collecting tube is provided with a sealing assembly; as a further description of the above-mentioned technical scheme: the sealing assembly comprises an upper chamber top threaded sealing cover, the inner thread of the upper chamber top threaded sealing cover is threadedly connected to the outside of the top end of the upper chamber collecting tube, and the bottom end of the lower chamber collecting tube is threadedly connected to the lower chamber top threaded sealing cover.

[0005] As a further description of the above technical solution: the top of the sample chamber is fixedly connected to the top inner wall of the upper chamber top threaded sealing cover, and the outside of the sample chamber is slidably connected to the inner wall of the upper chamber collection tube.

[0006] The utility model has the following beneficial effects: In the utility model, the sample inside the sample chamber is filtered multiple times by the filter screen 1, filter screen 2 and filter screen 3 inside the upper chamber collection tube, which can effectively remove the debris and impurities in the feces and retain the integrity of the parasite eggs. The threaded connection between the upper chamber collection tube and the upper chamber top threaded sealing cover, the threaded connection between the upper chamber collection tube and the lower chamber collection tube, and the threaded connection between the lower chamber collection tube and the lower chamber top threaded sealing cover form a closed environment during collection, reducing pollution, odor and leakage without requiring too many conventional laboratory consumables.
