Metabolic cage of laboratory mice

Abstract

The invention provides a metabolic cage of laboratory mice. The metabolic cage of the laboratory mice is used for solving the problem that manure and urine of the laboratory mice can not be completely separated in the prior art. The metabolic cage of the laboratory mice comprises a support, a mouse cage, a separation collecting device, a conical separator, a urine collecting ring and an excrement tube. The mouse cage is fixed on the support, a mesh is arranged on the bottom of the mouse cage, and the separation collecting device is arranged below the mouse cage. The separation collecting device comprises a funnel, and the size of an upper opening of the separation collecting device is matched with the size of the mesh. The lower end of the conical separator is in an opening design. The conical separator is arranged inside the funnel and is coaxial with the funnel, the size of an upper opening of the conical separator is smaller than the size of a lower opening of the conical separator, and the size of the lower opening of the conical separator is larger than the size of the neck portion of the funnel. An annular urine collecting groove is formed in the upper surface of the urine collecting ring, and a lower opening of the funnel is placed in the urine collecting groove. The urine collecting ring is obliquely arranged, a urinary catheterization opening is formed in the lowest end of the urine collecting ring, and a urine tube used for containing urine is arranged below the urinary catheterization opening. The excrement tube is arranged below the funnel and used for containing excrement, a filtering membrane is arranged on the opening portion at the upper end of the urine tube, and the filtering membrane can be used for stopping and preserving the excrement so that the manure and urine separation effect can be made to be more obvious.

Description

technical field [0001] The invention relates to the field of animal experiment equipment, in particular to a metabolic cage for experimental mice. Background technique [0002] The method of directly collecting animal metabolites with a feces-urine separation device is called the metabolic cage method. The metabolic cage is used to collect the urine and feces naturally excreted by experimental animals. It is a specially designed closed breeding cage for collecting various excreted substances of experimental animals, and some can also collect the carbon dioxide exhaled by experimental animals. Experimental rat metabolic cage is a breeding cage specially used to collect excrement of experimental rats. It is used for in vivo metabolism experiments of experimental rats. It can provide a comfortable living environment for experimental rats. It can quantify the drinking water and food of experimental rats, allowing experimental rats to naturally Metabolism, the separation device ...
