Description

Technical Field

[0001] This utility model specifically relates to a multi-layer three-dimensional cage structure for laboratory mice. Background Technology

[0002] In the field of biomedical research, laboratory mice are one of the most commonly used experimental animals, and the rationality of their housing and experimental environment has a crucial impact on the accuracy and reliability of experimental results. As the primary environment for the living and experimental procedures of laboratory mice, the quality of the mouse cage's structural design directly affects the efficiency and quality of the experiment.

[0003] Currently, open-cage rearing is the most common method for raising mice in laboratories. While this method offers advantages such as low equipment cost, ease of operation, convenient observation, and easy cleaning and disinfection of the cages, traditional mouse cages often have low space utilization as experimental scales expand and research requirements increase. Most cage designs are relatively simple, typically accommodating only one or a few mice to facilitate observation of individual subjects. This limits the number of mice that can be housed within a limited laboratory space. This not only increases the cost of laboratory space but also hinders large-scale experiments.

[0004] Therefore, it is necessary to invent a multi-layered three-dimensional cage structure for laboratory mice to solve the above problems. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes a multi-layer three-dimensional cage structure for laboratory mice, which can expand the breeding space for mice.

[0009] Multiple water feeders are installed on one side of the side plate, and the multiple water feeders correspond to the areas separated by multiple support layers. A feeding port is also provided on one side of the side plate on the side of the water feeder, and a feeding trough is installed outside the feeding port.

[0010] Preferably, the mounting plates on both sides and the supporting base plate are provided with symmetrical positioning grooves, and the sides and bottom of the side plates are provided with positioning strips corresponding to the positioning grooves. A handle is also installed on the top of the side plate. Multiple mounting holes are opened on the side plate corresponding to the water feeder, and the feeding trough is fixed to the outside of the feeding port.

[0011] Preferably, the bottom of the inner side of the feeding trough is sloped, and a cover plate is fixed to one side of its top. A flip-top head is connected to the cover plate, and the cover plate is fixed to one side of the top of the feeding trough by a hinge. The bottom of the feeding opening is also sloped.

[0012] Preferably, the ventilation plate is provided with multiple ventilation holes, and the ventilation plates are all arranged between adjacent support layers. The flip cover is also provided with multiple ventilation holes. The flip cover is fixed to the top side of the mounting groove by a hinge, and a handle is also provided on the bottom side of the flip cover.

[0013] Preferably, the support layer is inserted into the slot, and the inner side of the mounting plate is provided with a locking groove to match the support layer. Support blocks are installed at the bottom of the locking groove and the bottom of the inner side of the slot. The support layer is disposed on the support block, and a handle is provided on one side of the support layer.

[0014] Preferably, a transparent plate is installed in the middle of the other side plate, and the height of the transparent plate covers the experimental mouse housing space inside the mounting plate.

[0015] Preferably, the installation position of the ventilation plate is symmetrical to the installation position of the flip-top plate, and the inner side of the side plate contacts the edge of the support layer on the inner side of the mounting plate.

[0016] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are:

[0017] 1. This utility model achieves a multi-layer three-dimensional layout through a slot-type support layer, which improves space utilization. At the same time, each layer is equipped with an independent water feeder and feeding system to meet the requirements of laboratory mice for activity space. The mesh openings combined with the transparent observation board form a three-dimensional activity space, which effectively promotes natural behaviors such as climbing and exploration of mice and reduces the incidence of stereotyped behaviors.

[0018] 2. The symmetrical arrangement of the ventilation plate and the flip-top plate of this utility model forms a gradient pressure difference, which, together with the independent ventilation system, ensures that the ammonia concentration reaches the standard. The inclined design of the feeding trough and the sealing structure of the flip-top reduce the feed residue rate. The slot-type support layer, together with the support block locking structure, eliminates the risk of excrement leakage. Attached Figure Description

[0031] In this embodiment, multiple water feeders 6 are installed on one side plate 2, corresponding to areas separated by multiple support layers 5. Each water feeder 6 is fixed through mounting holes 24 on the side plate 2 to ensure that experimental mice in different areas can easily obtain water. A feeding trough 7 is installed on the side plate 2 outside the feeding port 21 located on one side of the water feeder 6. The bottom of the inner side of the feeding trough 7 is designed with a slope to facilitate the collection and retrieval of food. A cover plate 71 is fixed to one side of the top of the feeding trough 7 by a hinge. A flip-top 72 connected to the cover plate 71 facilitates the opening and closing of the feeding trough 7 to prevent food spillage and external contamination.

[0032] Reference Figure 3-4 Symmetrical positioning grooves 15 are provided on the mounting plates 11 on both sides and the supporting base plate 1.

Handles 23 are installed on the top of the side plates 2 to facilitate subsequent handling and movement of the entire cage.

[0034] Specifically, the bottom of the inner side of the feeding trough 7 is sloping, and a cover plate 71 is fixed on one side of its top. A flip cover head 72 is connected to the cover plate 71. The cover plate 71 is fixed to one side of the top of the feeding trough 7 by a hinge. The bottom of the feeding port 21 is also sloping.

The height of the transparent plate 8 covers the experimental mouse housing space inside the mounting plate 11 so that the experimenters can clearly observe the activities of the experimental mice in the cage.

[0039] Reference Figure 5-6 The installation position of the ventilation plate 12 is symmetrical to that of the flip-up plate 4, and the inner side of the side plate 2 contacts the edge of the support layer 5 on the inner side of the mounting plate 11.

[0040] In this embodiment, a mesh 3 is installed on the top of the mounting plates 11 on both sides to form a top protective structure for the cage. On one side of the mounting plate 11, multiple ventilation plates 12 are installed at corresponding positions between adjacent support layers 5, with ventilation holes 16 on the ventilation plates 12 facing inwards to allow air circulation. On the other side of the mounting plate 11, a flip-top plate 4 is fixed to the top side of the mounting slot 13 via hinges within multiple mounting slots 13. The ventilation holes 16 on the flip-top plate 4 are symmetrically positioned with the ventilation holes 16 on the ventilation plates 12, and a handle 41 on the bottom side of the flip-top plate 4 facilitates its opening and closing.

[0041] In this embodiment, a support layer 5 is inserted into multiple slots 14, and the locking groove 17 on the inner side of the mounting plate 11 matches the support layer 5. Support blocks 18 installed at the bottom of the locking groove 17 and the bottom of the inner side of the slot 14 provide stable support for the support layer 5.

[0042] In this embodiment, the cage adopts a multi-layered three-dimensional structure. The support layer 5 divides the cage space into multiple independent areas, effectively increasing the usable space and allowing for the simultaneous housing of multiple groups of experimental mice. This facilitates group experiments and management, improving experimental efficiency. Both the ventilation plate 12 and the flip-top plate 4 are equipped with multiple ventilation holes 16. The ventilation plate 12 is installed between adjacent support layers 5, and the flip-top plate 4 is symmetrically positioned with the ventilation plate 11, ensuring smooth airflow within the cage, timely replacement of fresh air, reducing the accumulation of harmful gases and odors, providing a favorable living environment for the experimental mice, and reducing the probability of disease occurrence.

[0043] In this embodiment, the water feeder 6 is installed in the area separated by the support layer 5, allowing the mice in each area to easily drink water without frequent cage movement. The sloping design of the bottom inner side of the feeding trough 7 helps to concentrate food and reduce food residue; the top cover 71 is connected by a hinge, which can effectively prevent dust and debris from entering the feeding trough 7, keeping the food clean and hygienic, and also preventing the mice from taking food out of the trough, thus maintaining the cleanliness of the cage.
