Laboratory mouse excrement collecting device

Abstract

The invention relates to a laboratory mouse excrement collecting device. The laboratory mouse excrement collecting device comprises a box body, a cover plate is arranged at the top of the box body, and three layers of barriers are arranged in the box body from top to bottom; the first-layer barrier is horizontally placed, and the space defined by the first-layer barrier, the box body and the cover plate is a mouse placing area; the second barrier and the third barrier are sieve plates, the second barrier and the third barrier are used for preventing excrement of mouse from falling down, and the second barrier and the third barrier are obliquely arranged and can be pulled out from one side of the box body; a urine collecting funnel is arranged below the third barrier, a urine collecting pipe is fixed below the funnel, and the urine collecting pipe is connected with a collecting bottle; a water feeding device and a food feeding device are arranged on the outer side of the box body, a food trough is fixedly arranged in the mouse placing area, and a food outlet of the food feeding device extends into the food trough; and a water outlet of the water feeding device extends into the mouse placing area from the side wall of the box body. According to the laboratory mouse excrement collecting device, and excrement and urine of the mouse can be effectively separated.

Description

Technical field [0001] The present invention relates to an experimental mouse excrement collecting device. Background technique [0002] The urine detection of mice is a comparative key physical and chemical indicator. Therefore, the urine to collect mice is a very critical step. The method of directly collecting animal metabolites directly with a manure separation device is the metabolic cage method. [0003] China's utility model patent ZL201310335359.X discloses a simple mouse as a cage, including a feed area, a metabolic area, a mesh, a negative row, a loop, a funnel, and a funnel. This kind of metabolic cage is simple, low cost, can be separated to a certain extent. However, this metabolic cage requires the operator to put mice from the breeding area to the metabolic area, requiring the operator to pay attention; if the manure separation is not thorough, the urine in the collecting pipe is easily mixed with feces; the entire device does not take closed measures, collect the ...

AI Technical Summary

Problems solved by technology

However, this kind of metabolic cage requires the operator to put the mice from the feeding area into the metabolic area, and the operator needs to pay attention at all times; the separation of feces and urine is not complete, and the urine in the collection tube is easily mixed with feces; the whole device does not take sealing measures, and the urine in the collection tube Fluid is volatile, resulting in changes in the concentration of urine components
