[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0026] The present invention will be further described below with reference to the embodiments.
[0027] Example:
[0028] Please refer to the appendix. Figures 1-4 This paper proposes a multifunctional open-type experimental cage for rodents. Cage 1 is designed as an open cage structure, which can effectively promote air circulation and maintain good ventilation within the cage, providing a good foundation for rodent rearing. It also facilitates researchers' observation of animal behavior from different angles. The top of cage 1 is designed as an opening, allowing for easy removal of the animals for experimental operations.
[0029] Specifically, the upper end of the cage 1 is provided with two groups of mounting seats 3, and the detachable top cover 2 is installed through the two groups of mounting seats 3. The opening above the cage 1 can be sealed through the top cover 2 to avoid the escape of rodents during feeding. At the same time, the surface of the top cover 2 is provided with an operation port 4, and the researcher can make the cage 1 have an opening above without opening the top cover 2 through the operation port 4, so as to facilitate the quick taking out of the rodents in the cage 1, thereby reducing the influence on the animals when the top cover 2 is opened, causing the rodents to be uneasy and fearful, further causing the stress of the rodents, and affecting the accuracy of the experimental data.
[0030] The vertical rods 5 are uniformly distributed on the outside of the operation port 4 on the top cover 2, and the vertical rods 5 are inserted into the inside of the cage 1. First, the size of the opening above the cage 1 can be reduced through the setting of the operation port 4, and then the surrounding of the operation port 4 can be shielded through the vertical rods 5, so as to avoid the rodents climbing through the cage 1 and escaping through the operation port 4. And the surface of the vertical rod 5 is provided with a smooth coating, which further reduces the friction when the rodents grab, so as to avoid the climbing of the rodents.
[0031] The top cover 2 is provided with two groups of operation ports 4, so that the researcher can insert both hands into the cage 1 when operating the rodents in the cage 1, improving the convenience of operation. The top cover 2 is slidingly installed between the two groups of mounting seats 3, so that when the researcher operates the rodents in the cage 1 through the operation port 4, the relative position of the operation port 4 on the cage 1 can be adjusted, further facilitating the experimental operation on the rodents at different positions in the cage 1, and improving the convenience of the device in use.
[0032] The lower surface of the cage 1 is provided with two groups of soft cloth 6, the distance between the two groups of soft cloth 6 is the same as the distance between the two groups of operation ports 4, and the area of the soft cloth 6 is larger than the area of the operation port 4. When the researcher completes the experimental operation, in order to prevent the rodents from jumping out of the operation port 4 and escaping, the top cover 2 is controlled to slide on the mounting seat 3, so that the two groups of operation ports 4 on the top cover 2 are aligned with the two groups of soft cloth 6 respectively. Further, when the rodents try to escape from the operation port 4, when the rodents are located on the outside of the soft cloth 6 and jump out of the operation port 4, they will be blocked by the vertical rods 5. When the rodents step on the soft cloth 6 and jump out of the operation port 4, the soft cloth 6 is relatively loose, which causes the rodents to be unable to obtain enough supporting force when jumping, thereby affecting the height and distance of jumping, effectively avoiding the escape of the rodents. Further, through the setting of the vertical rods 5 and the soft cloth 6, the cage 1 can be kept open through the operation port 4 without being watched, and the escape of the rodents can also be prevented.
[0033] More specifically, the surface of the mounting base 3 is provided with a sliding groove 301, the top cover 2 is inserted in the sliding groove 301, the inner wall of the sliding groove 301 is provided with mounting holes 302 distributed at equal distances in a circle, the inner part of each group of mounting holes 302 is inserted with a ball 303, and the top cover 2 abuts against the surface of the ball 303. When the top cover 2 linearly slides in the sliding groove 301, the ball 303 can reduce the friction of the top cover 2 sliding on the mounting base 3, further improve the sliding fluency of the top cover 2, reduce the sound when the top cover 2 slides, and avoid the influence of noise on rodents.
[0034] The length of the top cover 2 is greater than the length of the cage 1, and the two groups of operation ports 4 are located at the upper central position of the top cover 2, so that when the top cover 2 slides above the cage 1, the two groups of operation ports 4 and the cage 1 are aligned at different positions inside the cage 1, thereby facilitating the taking and experimental operation of rodents at different positions in the cage 1.
[0035] The difference is that the cage 1 comprises a fixed frame 101 and a movable frame 102, the bottom of the fixed frame 101 is provided with a bottom plate, and the net cage space is formed by the fixed frame 101 to limit the rodents. The surface of the fixed frame 101 is provided with vertical ribs 103 distributed uniformly, the surface of the movable frame 102 is provided with horizontal ribs 104 distributed uniformly, and the vertical ribs 103 and the horizontal ribs 104 are vertically distributed. Further, the vertical ribs 103 and the horizontal ribs 104 form a grid distribution, which reduces the pore size of the surface of the cage 1, thereby increasing the difficulty of escape of rodents.
[0036] It is worth noting that the surface of the vertical rib 103 is slidingly installed with a clamping block 105, and the horizontal rib 104 is fitted in the clamping block 105, further enabling the movable frame 102 to be slidingly installed on the fixed frame 101 in the vertical direction. When the fixed frame 101 and the movable frame 102 are used and adhere to stains, the clamping block 105 can realize the quick disassembly of the fixed frame 101 and the movable frame 102, thereby facilitating the cleaning of the cage 1.
[0037] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
