Description

Technical Field

[0001] The utility model relates to medical research experimental equipment, in particular to a novel mouse feces collecting device for experiments. Background Art

[0002] Intestinal flora-related detection has been a popular medical research topic in recent years, and the detection method is to collect feces or colon contents. Among them, the feces collection method does not require the dissection of experimental animals, which is more conducive to long-term observation of living bodies, and is therefore more convenient and commonly used. However, the traditional feces collection method is to fix the feces collection container on the excretion site of rodents for collection. This method has the following disadvantages: the collection container is inconvenient to fix and is easy to fall off and lose, the collection container is easily contaminated during the activities of rodents, the collected feces and urine are mixed together, and the integrity is easily destroyed by urine, etc. Once contaminated with foreign matter, it will directly affect the quality of the fecal sample, causing great trouble to scientific research. For this reason, we need a feces collection device that can combine the characteristics of sampling, anti-falling, easy collection and keeping the sample contamination-free. Utility Model Content

[0003] The utility model provides a novel experimental mouse feces collection device specially used for collecting mouse feces. The device is convenient and quick to collect feces, and can avoid the shedding and contamination of feces samples to the greatest extent, thereby ensuring the rigor and accuracy of scientific research experiments, and greatly facilitating the application of collecting mouse feces for intestinal flora detection in medical research.

[0004] The utility model is achieved through the following technical solutions:

[0005] A feces collection device specifically for mice and rats, comprising an upper operating platform, a paper roll fixing device, and a plurality of supporting legs supported on the bottom of the upper operating platform;

[0006] The upper operating table includes a frame and a rat fixing table, a feces collection table, and a sample dispensing table arranged on the frame and arranged in sequence from one side to the other in the transverse direction; a through slot for passing a paper towel is provided between the rat fixing table and the feces collection table, extending in the longitudinal direction and penetrating the upper and lower surfaces;

[0007] The rat fixing platform is composed of crisscross grids laid in the frame, which are convenient for rats to grab and pounce on;

[0008] The stool collection platform is composed of a plurality of support rods extending in the longitudinal direction and arranged in sequence in the transverse direction within the frame;

[0009] The sample dispensing platform comprises a flat plate fixedly mounted on the frame and laid horizontally;

[0010] The roll paper fixing device comprises a support base fixed on the frame and located on one longitudinal side below the through slot, and a fixing rod provided on the support base and extending from the support base to the other longitudinal side for inserting the roll paper.

[0011] During use, the irradiated sterilized sterile roll of paper is placed outside the fixed rod, the free end of the roll of paper is passed through the bottom of the groove, and then pulled to the side of the feces collection platform, and then the mouse is grabbed and made to pounce on the mouse fixing platform. Since the mouse fixing platform is a stainless steel grid, the mouse will naturally grab the grid, and then pulling the mouse's tail will stimulate its defecation, and the feces will fall on the roll of paper on the feces collection platform. If there is urine, it can be directly absorbed by the roll of paper. Then continue to pull the roll of paper, pull the roll of paper with mouse feces to the sample packaging platform, and then package the mouse feces on the roll of paper. At the same time, the new roll of paper pulled to the feces collection platform can be used for the next experimental mouse operation process. This method ensures the effective collection of scientific research samples, sterile quality, high efficiency and convenience.

[0012] Preferably, in order to facilitate fixing of the roll of paper, the free end of the fixing rod is provided with an annular flange to prevent the roll of paper from falling.

[0013] Preferably, in order to facilitate cutting of the roll of paper on the sample dispensing table, a serrated strip extending in the longitudinal direction with the blade facing upward is provided on the lateral side of the upper surface of the sample dispensing table close to the feces collection table.

[0014] Preferably, the upper surface of the flat plate of the sample dispensing platform and the upper surface of the support rod are located at the same horizontal plane.

[0015] Specifically, in order to be more durable, the grid is a stainless steel grid.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The novel experimental mouse feces collection device described in the present invention is convenient and quick to collect, does not require the collection container to be fixed at the mouse's excretion site, and is applicable to mice of various body shapes. When used, the mice are accurately fixed, and the mice have high compliance, comfort, and cooperation. It can minimize the impact of fecal sample shedding and contamination on scientific research results, ensure the quantity and quality of experimental samples, and thus ensure the rigor and accuracy of scientific research experiments. In addition, the present invention has high collection efficiency, can reduce the burden on staff, and is simple, safe, and low-cost to operate. Therefore, it has great significance in medical research involving the collection of mouse feces. BRIEF DESCRIPTION OF THE DRAWINGS
