Description

Technical Field

[0001] The utility model relates to the technical field of mouse sampling and metabolism equipment, in particular to a mouse sampling and metabolism cage. Background Art

[0002] A mouse sampling and metabolism cage is an experimental device specifically used for studying the metabolism of mice. It can collect various excreta (such as urine, feces) and other samples of mice in a relatively independent environment, and study various physiological processes of mice such as energy metabolism and substance metabolism (such as protein, sugar, and fat metabolism) through the analysis of these samples;

[0003] Currently, the following risks may exist during the use of the existing mouse sampling and metabolism cage:

[0004] 1. There will be areas for collecting mouse urine and feces and a feeding trough for placing mouse food inside. Due to the small space inside the sampling and metabolism cage, when mice excrete or eat, it is easy to bring feces and urine into the feeding trough area, or bring food into the excretion area. In this way, sample contamination will occur, affecting the accuracy of later analysis, and at the same time, it may contaminate the mouse food and affect the health of the mice;

[0005] 2. The area for collecting feces and urine samples inside the sampling and metabolism cage is inside the cage, and the area for collecting feces and urine samples is fixed. Conducting multiple samplings is relatively cumbersome and is not conducive to sampling personnel to take samples regularly.

[0006] In summary, there is a need for a mouse sampling and metabolism cage that is not easily contaminated with samples and is convenient for sampling. Content of the Utility Model

[0037] Embodiment 2

[0038] As Figures 2 - 7 shown, on the basis of the above embodiments, the following content is further given in this embodiment:
