Technical Field

[0001] The utility model relates to the technical field of feces collection, in particular to a feces collection device for experimental animals. Background Art

[0002] Intestinal flora is a hot topic in biomedical research. It plays an important role in the occurrence and prevention of many diseases such as intestinal diseases, tumors, and nervous system diseases. Collecting fresh feces is the first condition for studying intestinal flora. Feces collection is often based on metabolic cage breeding supplemented by manual collection.

[0003] The utility model with the announcement number CN210782454U discloses an animal feces collection device including a cage body, a collection assembly, a collection cage and a temperature control element. The lower end of the cage body is open and the cage body is configured to accommodate experimental animals. The collection assembly is located below the cage body. The collection assembly includes a shell, a mesh body and a filter element. The two ends of the shell body are open and the upper end of the shell body is corresponding to the lower end of the cage body. The mesh body is arranged inside the shell body. The upper end surface of the mesh body is configured to support the experimental animal. The filter element is sandwiched between the circumference of the mesh body and the shell body. The filter element is configured to absorb urine of the experimental animal. The collection cage is provided with a collection hole corresponding to the lower end of the shell body.
