Description

High-efficient collection device of laboratory mouse crowd excrement and urine

Technical Field

The utility model belongs to the technical field of biological assay, concretely relates to high-efficient collection device of laboratory mouse crowd's excrement and urine.

Background

The study of intestinal microorganisms is an extremely important field in life science, and the collection of rat or mouse feces is an essential operation for the study of intestinal microorganisms. Because of experimental needs, rats or mice are usually reared in cages, and when feces need to be collected, each is placed in a metabolic cage separately, and then the feces are collected from cage to cage. Long-term experiments show that the prior excrement collecting device has the following defects that the occupied area is large, and the device is inconvenient to move when a plurality of animal excrement needs to be collected simultaneously; when excrement is collected, due to special research requirements such as research on intestinal anaerobes and the like, the time of exposing the excrement in the air is shortened as much as possible, the excrement is collected in a collecting pipe and is covered as soon as possible, each cage of the conventional device is only provided with one excrement collector, the defecation time of an experimental mouse cannot be determined, and the excrement collection condition of each collector needs to be checked for many times, so that time and labor are wasted; after the excrement is collected, in order to prevent bacteria cross contamination, the excrement collecting device needs to be cleaned and disinfected one by one with larger workload. Especially, intestinal microorganism research often involves the multifactor grouping experiment, and when experimental mouse crowd scale increases to hundreds of experimental animals, current mouse excrement and urine collection device is unable to handle the collection clearance demand of the large amount of excrement and urine of mouse crowd especially.

SUMMERY OF THE UTILITY MODEL

To the problem, the utility model aims at providing a high-efficient collection device of laboratory mouse crowd's excrement and urine.

In order to achieve the purpose, the utility model adopts the following technical proposal:

an efficient experimental mouse group excrement collecting device comprises mouse cages, collecting drawers and a support, and is characterized in that the mouse cages consist of single cages which are opposite in pairs, several in a row and connected together in a plane mode, a cage cover is arranged at the upper part of each cage, a hollowed cage bottom grid is arranged at the bottom of each cage, and the left side, the right side, the front side and the rear side of each cage are enclosing plates; the bracket consists of small box-type spaces with the same number and arrangement as the cages, each small box-type space corresponds to the upper cage respectively, the inner side of the bracket of each small box-type space contains a plurality of rows of clamping grooves which are arranged up and down, and each clamping groove corresponds to the bulge at the bottom of the collection drawer and is used for fixing the collection drawer; every row of draw-in groove of a line of support corresponds a collection drawer, collect the drawer and constitute side by the little drawer of several that handle and connecting rod are connected, the quantity and the position of little drawer correspond with single file cage utensil, and every little drawer side is the inclined plane of interior height outside low, and outside bottom contains two rows of urine leakage mouths, and urine leakage mouth lower part has the collection canal.

Preferably, the urine collecting channel is in a channel shape with two closed sides, an opening at the outer side, a low left side and a high right side.

Preferably, the inner side of the bracket comprises an upper row of clamping grooves and a lower row of clamping grooves, namely a clamping groove A and a clamping groove B.

Preferably, the squirrel cage is composed of single cages which are opposite pairwise and are connected together in a plane manner, 6 cages and 12 cages in one line are connected together in two lines, the support is composed of small box-type spaces at intervals, the number and arrangement of the small box-type spaces are the same as those of the cages, and the collection drawer is composed of 6 small drawers which are connected through handles and connecting rods.

The utility model discloses owing to take above technical scheme, it has following advantage:

1) each cage corresponds to the upper drawer and the lower drawer, and when the upper-layer excrement of an uncertain mouse is collected or cleaned, the lower-layer drawer can still continuously collect the excrement so as to improve the collection efficiency.

2) Six cages are pieced together one row, and following two-layer every layer of drawer links together, can realize collecting faecal batch processing, need not to look over the defecation condition in turn by the squirrel cage, only needs regularly to extract individual layer drawer and collects, can guarantee the high efficiency of extensive experiment and go on.

3) The collection drawer can be taken out for cleaning after being used, and the workload of removing and cleaning one by one is reduced.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, but the scope of the present invention is not limited thereto. All equivalent replacements of the number and the size of the squirrel cages made by the person skilled in the art on the basis of the present invention fall within the scope of protection of the present invention.

The utility model provides a high-efficient collection device of laboratory mouse crowd's excrement and urine is constituteed and is included: 1. the novel urine collector comprises a squirrel cage, 2 collecting drawers, 3 supports, 4 cage covers, 5 cage bottom grids, 6 clamping grooves A, 7 clamping grooves B, 8 drawer handles, 9 urine leakage openings, 10 connecting rods, 11 bottom protrusions, 12 urine collecting channels and 13 drawer side faces. As shown in fig. 1, 2, 3, 4, 5 and 6.

The squirrel cage 1 is composed of twelve single cages which are opposite in pairs and connected together in a plane manner, wherein each cage is provided with a cage cover 4 at the upper part, a hollowed cage bottom grid 5 at the bottom and coamings at the left side, the right side, the front side and the rear side. The bracket 3 is composed of twelve small box-type spaces at intervals, and each small box-type space corresponds to the upper cage respectively. The inner side of the bracket comprises an upper clamping groove 6 and a lower clamping groove 7 which correspond to the bulges 11 at the bottom of the collection drawer 2 and are used for fixing the collection drawer 2. The collecting drawer 2 is composed of 6 small drawers connected by a handle 8 and a connecting rod 10, and the side surface of each drawer is an inclined surface with a high inside and a low outside. The bottom of the outer side of the urinal is provided with two urine drainage ports 9, and the lower part of the urine drainage port is provided with a urine collecting channel 12.
