Abstract
The utility model relates to a room of animals for experiments, in particular to an improved metabolism cage for laboratory mice. The metabolism cage comprises a mouse cage (1) of which the lateral surface is provided with a food accommodating container (4) and a water accommodating container (3) and which is made of metal grid bars, a conical funnel (11), an excrement containing disc and a urine accommodating container (12), and is characterized in that the excrement containing disc, the conical funnel (11) and the urine accommodating container (12) are arranged under the bottom of the mouse cage (1) from top to bottom; and the excrement containing disc is a first meshed sheet (9) of which the pore diameter is smaller than grain sizes of excrement of laboratory mice. The metabolism cage is good in effect of separating the excrement from urine, and the urine is not sprinkled outside the urine accommodating container.
Description
Technical field
The utility model relates to the room of animal for research, is specifically related to a kind of metablism device of experimental mouse.
Background technology
The experimental mouse metabolic cage is the metabolism device commonly used that experimental mouse urine and ight soil detect and frequent micturition is counted, and plays an important role at medical medicine toxicity test and the physiological research of urinary system pathology.Accurate urine collecting need to separate urine, the excrement of rat, accurately collects whole urines, to calculate the urine amount and to collect urine and carry out biochemical analysis.Granted publication number discloses a kind of " large and small mouse metabolic cage " for the utility application of CN 2705008Y, this metabolic cage, comprise mouse cage, feeding trough feed trough, drinking bowl and faeces collector, faeces collector is arranged at the mouse cage bottom, it is characterized in that, faeces collector is comprised of funnel, ball separator, urine-containing cup and dropping tray, and funnel is positioned at the beneath side of mouse cage cage, and its upper inlet is over against the coop base net grid; Ball separator is suspended on the lower outlet below of funnel, and the ball separator trans D is more than or equal to lower outlet diameter; Urine-containing cup is placed in the dropping tray and is positioned at the ball separator below, and the rim of a cup diameter of urine-containing cup is less than or equal to the ball separator trans D.Although the described metabolic cage of above-mentioned patent application can be collected urine and the ight soil of experimental mouse, obviously has following deficiency: 1, lack the frequent micturition counting device.2, dropping tray is positioned at the below of urine-containing cup, and the rim of a cup of urine-containing cup must be less than the diameter of ball separator, therefore, first when the amount of urinating of experimental mouse is larger, urine then is spread across outside the urine-containing cup, and second ight soil easily sticks to the ball separator surface of urine and being flushed in the urine-containing cup of again being flowed down; Above-mentioned two point defects have a strong impact on the calculating of precision and the urine amount of composition detection in the urine.
Summary of the invention
In view of the existing deficiency of prior art, a kind of modified experimental mouse of the technical problems to be solved in the utility model metabolic cage, this metabolic cage be excrement, urine good separating effect not only, and urine can not be spread across outside the chamber pot container.
The scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of modified experimental mouse metabolic cage, this metabolic cage comprises that the side is provided with mouse cage, conical hopper, dropping tray and chamber pot container that the employing metal grizzly bar of food container and water container is made, it is characterized in that, described dropping tray, conical hopper and chamber pot container be located at successively from top to bottom at the bottom of the mouse cage cage under, and described dropping tray is that the aperture is less than the first net sheet of experimental mouse ight soil particle diameter.
For setting up the function of frequent micturition counting, an improvement project of metabolic cage described in the utility model is, as being provided with the second net sheet that can lay the urine colour developing test paper that carries out the frequent micturition counting between dropping tray the first net sheet and the conical hopper.
Metabolic cage described in the utility model, wherein, described the first net sheet is located in the first slot, and described the second net sheet is located in the second slot; Above-mentioned the first slot and the first net sheet and the second slot and the second net sheet form respectively a drawer-type structure, and this structure both had been convenient to sampling, also was convenient to disassembly, cleaning.
Urine colour developing test paper is to utilize transparent anhydrous cupric sulfate (CuSO
4) crystal meets water and become blue cupric sulfate pentahydrate (CuSO
45H
2O) principles of chemistry of crystal are made, and its concrete method for making is, with common A3 paper be infiltrated on copper/saturated copper sulphate solution in, then put into the oven dry in 40 minutes of 300 degrees centigrade baking boxs.When the urine of experimental mouse is spread across on the described urine colour developing test paper, anhydrous cupric sulfate then can become rapidly cupric sulfate pentahydrate, just shows blue patch trace.Because cupric sulfate pentahydrate is just beginning dehydration more than 100 ℃, so formed blue patch trace can remain the research for the experimenter for a long time on the urine colour developing test paper.
The utility model utilizes the physical state of experimental mouse ight soil and urine dexterously, adopt the net sheet as dropping tray, and make it to be positioned at conical hopper it, not only realized ight soil and urine separation, and overcome urine that prior art adopts ball separator separating experiment mouse ight soil and urine to cause and be spread across urine-containing cup (being chamber pot container described in the utility model) ight soil outer and that stick to the ball separator surface and easily rushed in defective in the urine-containing cup.
