Technical Field
[0001] This utility model relates to the field of animal metabolic cage technology, specifically a metabolic cage for diabetic modeling animals with independent compartments. Background Technology
[0002] Animal metabolic cages are important research equipment in the field of clinical medical research, mainly used to simultaneously monitor basic physiological data such as energy metabolism, food intake, and water intake of experimental animals.
[0003] Traditional animal metabolic cages typically employ an integrated structural design, with animals placed directly on the bottom mesh of the cage. Lacking effective isolation measures, animal excrement produced during metabolism adheres directly to the cage bottom and mixes with the animal's activity area. This not only easily leads to cross-contamination, affecting the accuracy and purity of metabolite collection, but also hinders subsequent cleaning and collection of metabolites. The cleaning process can cause unnecessary disturbance and stress to the animals, thereby affecting the reliability of experimental results.
[0004] To address the above technical issues, it is necessary to design a metabolic cage for diabetic model animals with independent compartments. Utility Model Content
[0005] The purpose of this invention is to provide a metabolic cage for diabetic modeling animals with independent compartments, which has the advantages of isolating the animal's metabolism and facilitating the collection of metabolites. It solves the problem that traditional animal metabolic cages usually adopt an integral structure design, in which the excrement produced by the animal during metabolism will directly adhere to the bottom of the cage, making it inconvenient to collect metabolites.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a metabolic cage for diabetic model animals with independent compartments, comprising a breathable cage, a transparent box fixedly connected to the bottom of the breathable cage, a box door movably connected to the surface of the breathable cage via a rotating shaft, a partition provided in the inner cavity of the breathable cage, the top of the partition extending through to the top of the breathable cage and fixedly connected to a first sealing plate, a rotating rod movably connected to the inner wall of the breathable cage, a conveyor belt sleeved on the surface of the rotating rod, a scraper provided at the bottom of the conveyor belt, a conveying pipe provided in the inner cavity of the breathable cage, and a spray pipe connected to the surface of the conveying pipe.
[0007] Preferably, one end of the conveying pipe extends to the outside of the ventilated cage, a disc is fitted on the surface of the conveying pipe, a bolt is connected through the surface of the disc, the bolt passes through the disc and contacts the ventilated cage, and the bolt is threadedly connected to the disc.
[0008] Preferably, the front and rear sides of the scraper are fixedly connected to the inner wall of the air cage, the top of the scraper is in contact with the bottom of the conveyor belt, the rear end of the rotating rod extends through to the outside of the air cage, the rear end of the rotating rod is fixedly connected to a turntable, and the rear side of the turntable is fixedly connected to a rocker arm.
[0009] Preferably, a first pad is fixedly connected to the inner wall of the ventilated cage, the bottom of the partition plate contacts the first pad, and a first handle is fixedly connected to the top of the first sealing plate.
[0010] Preferably, a support plate is provided on the top of the first pad, the top of the support plate extends through to the outside of the ventilated cage and is fixedly connected to a second sealing plate, and a second handle is fixedly connected to the surface of the second sealing plate.
[0011] Preferably, the inner cavity of the transparent box is movably connected to a drawer, the surface of the drawer is fixedly connected to a handle, the bottom of the front of the drawer is connected to a drain pipe, and the surface of the drain pipe is threaded with a pipe cap.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting up a partition, divides the ventilated cage into two independent spaces. Animals are raised on a conveyor belt, which is cleaned periodically or according to the amount of excrement. This allows the excrement produced by the animals during metabolism to be transported downwards through the conveyor belt to the designated collection location, greatly simplifying the cleaning process and improving cleaning efficiency. Before cleaning, the partition is opened to guide the animals to the support plate, without removing the animals from the cage. This reduces interference with the animals during cleaning, minimizes the impact of animal stress on experimental results, facilitates the collection and cleaning of metabolites, and avoids pollution of the laboratory environment caused by removing animals from the cage.
[0015] 2. During the operation of the conveyor belt, the scraper can continuously and effectively remove residual excrement and stains from the surface of the conveyor belt, ensuring the cleanliness of the conveyor belt and preventing the accumulation of excrement on the conveyor belt from affecting the metabolic environment of animals and the accuracy of experimental data.

[0021] Please see Figures 1-4 A metabolic cage for diabetic model animals with independent compartments includes a ventilated cage 1, a transparent box 2 fixedly connected to the bottom of the ventilated cage 1, a box door 3 movably connected to the surface of the ventilated cage 1 via a rotating shaft, a partition 4 provided in the inner cavity of the ventilated cage 1, the top of the partition 4 extending through to the top of the ventilated cage 1 and fixedly connected to a first sealing plate 5, a rotating rod 6 movably connected to the inner wall of the ventilated cage 1, a conveyor belt 7 sleeved on the surface of the rotating rod 6, a scraper 8 provided at the bottom of the conveyor belt 7, a conveying pipe 9 provided in the inner cavity of the ventilated cage 1, and a spray pipe 10 connected to the surface of the conveyor pipe 9. By setting the partition 4, the ventilated cage 1 is divided into two independent spaces. The animal is placed on top of the conveyor belt 7, and the excrement produced by the animal during metabolism can be conveyed downward through the conveyor belt 7 to transport the excrement to the designated collection location, which greatly simplifies the cleaning process, improves cleaning efficiency, reduces interference to the animal during the cleaning process, reduces the impact of animal stress on experimental results, and facilitates the cleaning and collection of metabolites.
[0022] Please see Figures 1-2 One end of the conveying pipe 9 extends to the outside of the ventilation cage 1. A disc 11 is fitted on the surface of the conveying pipe 9. A bolt 12 is connected through the surface of the disc 11. The bolt 12 passes through the disc 11 and contacts the ventilation cage 1. The bolt 12 is threadedly connected to the disc 11. By setting the disc 11 and the bolt 12, the disc 11 can be fixed. The rotation angle of the conveying pipe 9 can be flexibly adjusted according to the actual situation. The conveying pipe 9 drives the spray pipe 10 to rotate, so that the spray pipe 10 is aligned with the contact position between the scraper 8 and the conveyor belt 7, and sprays water to wash the scraper 8, ensuring that the scraper 8 is thoroughly and effectively washed, and improving the cleaning effect.
[0023] Please see Figures 1-4The scraper 8 is fixedly connected to the inner wall of the ventilation cage 1 on both the front and rear sides. The top of the scraper 8 contacts the bottom of the conveyor belt 7. The rear end of the rotating rod 6 extends to the outside of the ventilation cage 1. The rear end of the rotating rod 6 is fixedly connected to the turntable 19. The rear side of the turntable 19 is fixedly connected to the rocker arm. During the operation of the conveyor belt 7, the scraper 8 can continuously and effectively scrape off the excrement and stains remaining on the surface of the conveyor belt 7, ensuring the cleanliness of the conveyor belt 7 and preventing the accumulation of excrement on the conveyor belt 7 from affecting the metabolic environment of the animals and the accuracy of experimental data. By setting the turntable 19 and the rocker arm, it is easy to drive the conveyor belt 7 to rotate, which facilitates the transport of metabolites.
[0024] Please see Figures 1-3 The inner wall of the ventilated cage 1 is fixedly connected to a first pad 13. The bottom of the partition 4 is in contact with the first pad 13. The top of the first sealing plate 5 is fixedly connected to a first handle. The first pad 13 provides a stable support platform for the partition 4. During animal activity, the partition 4 will be subjected to a certain external force. The first pad 13 can enhance the stability of the partition 4, prevent the partition 4 from shaking or shifting, ensure the stability of the independent compartment, and guarantee the reliability of the experimental environment.
[0025] Please see Figures 1-3 A support plate 14 is provided on the top of the first pad 13. The top of the support plate 14 extends through to the outside of the ventilation cage 1 and is fixedly connected to the second sealing plate 15. A second handle is fixedly connected to the surface of the second sealing plate 15. By providing the support plate 14, the inner cavity of the ventilation cage 1 can be supported, and the animal can be supported. By providing the second handle, it is convenient to pull the second sealing plate 15 and the support plate 14 to move, and to disassemble and clean the support plate 14.
[0026] Please see Figure 1 The inner cavity of the transparent box 2 is movably connected to a drawer 16, and a handle is fixedly connected to the surface of the drawer 16. The bottom of the front of the drawer 16 is connected to a drain pipe 17, and a pipe cap is threaded onto the surface of the drain pipe 17. Metabolites can be collected in the drawer 16. Experimenters can easily pull out the drawer 16 for cleaning by using the handle, avoiding the inconvenience of direct contact with metabolites and improving cleaning efficiency and hygiene. The design of the transparent box 2 also makes it convenient for experimenters to observe the collection of metabolites in the drawer 16 and clean it in a timely manner. By setting up the drain pipe 17 and the pipe cap, it is easy to drain animal urine from the inner cavity of the drawer 16.
[0027] Please see Figure 4The inner cavity of drawer 16 is equipped with a filter frame 20, and a second pad 18 is fixedly connected to the inner wall of drawer 16. The top of the second pad 18 contacts the filter frame 20. The bottom of the transparent box 2 is fixedly connected with a support leg. The filter frame 20 can separate solid and liquid metabolites. During the metabolism process, solid excretions will remain on the filter frame 20, while liquid urine will flow into the bottom of drawer 16 through the filter frame 20. This separation method facilitates the separate processing and analysis of metabolites in different forms, improving the accuracy and efficiency of experimental data analysis. The filter frame 20 is supported by the second pad 18.
[0028] In use, the partition 4 divides the ventilated cage 1 into two independent spaces. Animals are usually placed on the conveyor belt 7, and animal metabolites fall onto the conveyor belt 7. When cleaning metabolites, the first sealing plate 5 is moved upward, causing the partition 4 to move upward, driving the animal onto the support plate 14. Then, the partition 4 is reset to isolate the animal. The rotating rocker causes the turntable 19 to rotate, which in turn causes the conveyor belt 7 to rotate. The conveyor belt 7 transports metabolites to the inner cavity of the filter frame 20 below. The filter frame 20 filters the liquid in the metabolites. The scraper 8 scrapes off the metabolites adhering to the surface of the conveyor belt 7. The drawer 16 is pulled to disassemble it, making it easy to pour out the metabolites. When cleaning the conveyor belt 7, an external water pipe is fitted on the surface of the conveyor pipe 9 to supply water to the inner cavity of the conveyor pipe 9. The water is sprayed out through the spray pipe 10 and sprayed between the scraper 8 and the conveyor belt 7 to clean the scraper 8 and the conveyor belt 7.
[0029] In summary, this metabolic cage for diabetic modeling animals with independent compartments, through the use of a breathable cage 1, a transparent box 2, a partition 4, a first sealing plate 5, a rotating rod 6, a conveyor belt 7, and a scraper 8, solves the problem that traditional animal metabolic cages, which typically use an integral structure design, cause animal excrement to adhere directly to the bottom of the cage during metabolism, making it inconvenient to collect metabolites.
