Description

Technical Field

[0001] The present application relates to the technical field of indoor laboratory mouse breeding, and in particular to a cage rotating cage rack for laboratory mice with an isolation bag. Background Art

[0002] Mice are the most common experimental animals and are indispensable in medicine, vaccine production, biological drug production, surgical practice drills, drug and food quality inspection and safety evaluation, and life science research.

[0003] In laboratories, mouse cages are usually used for breeding and experimental observation of experimental mice. When conducting different experiments, experimental mice with different breeding conditions need to be raised in different mouse cages according to the experimental requirements. This leads to the use of multiple mouse cages in the laboratory. When placing multiple mouse cages, the bottom space is limited. Therefore, there are usually two ways to place the mouse cages. One is to place multiple mouse cages together by stacking them in layers, and the other is to hang the mouse cages in the air.

[0004] However, in actual use, it is found that the above two cage placement methods have the following problems:

[0005] 1. In the first method, when there are many layers of cages, due to the different heights of different experimenters, when the cages on the upper layer need to be replaced, watered or ventilated, the cages on the upper layer need to be taken down before the operation, and it is difficult for shorter experimenters to take and put the cages on the upper layer. The second method also has the above problem when the cages are suspended in the air;

[0006] 2. When the above two methods are used to take and place the mouse cages, the experimenters are in direct contact with the mouse cages when taking them, especially when the mouse cages need to be replaced. This can easily cause quality contamination of the laboratory mice, thereby affecting the breeding quality of the laboratory mice.

[0007] In summary, the existing mouse cage placement method is inconvenient to use and easily causes pollution to the quality of laboratory mouse breeding. Utility Model Content

When in use, water is passed through the water inlet 75 on the isolation bag 7, and water is supplied to the first water inlet pipe 631 and the second water inlet pipe 641 respectively through the water inlet 75, so that water can be supplied to all cage boxes 4 in the isolation bag 7 at the same time, which is simple and convenient to use.

[0061] Reference Fig.10 and Fig.12 The second water rack 62 is divided into a first rack 621, a second rack 622 and a third rack 623. The second rack 622 is fixed on the first water rack 61. The first rack 621 is located at the top of the second rack 622. The third rack 623 is located at the bottom of the second rack 622. The first rack 621 and the third rack 623 both slide on the second rack 622. Four second electric guide rods 66 are provided, and the telescopic directions of two of the second electric guide rods 66 are toward the top of the cage frame 1, and the telescopic directions of the other two second electric guide rods 66 are toward the bottom of the cage frame 1.

[0062] Reference Fig.10 and Fig.12In the present embodiment, the first water inlet pipe 631 and the second water inlet pipe 641 are both flexible hoses. When in use, the first frame 621 is driven to be extended or retracted by two second electric guide rods 66, thereby driving the second water inlet pipe 641 on the first frame 621 to move its position. The third frame 623 is controlled to be extended or retracted by another two second electric guide rods 66, thereby driving the second water inlet pipe 641 on the third frame 623 to move its position. In this way, the second water inlet pipe 641 is prevented from affecting the circulation movement of the cage box 4 without affecting the normal use of the automatic drinking water module 6.

[0063] The implementation principle of the embodiment of the present application is as follows: when in use, a clean cage box 4 is placed in the transfer cylinder 72. After disinfection, the experimenter replaces the used dirty cage box 4 with the clean cage box 4 through the operating gloves 78 and places it on the mounting seat 21. The dirty cage box 4 is placed in the transfer cylinder 72 and can be taken out from the outside of the isolation bag 7. Then the motor 54 is controlled to start, driving the sprocket 51 to rotate, and the chain 53 to rotate synchronously, thereby driving the cage box 4 to move synchronously with the rotation of the chain 53, so as to rotate the cage box 4 at the upper level to the lower level, and rotate the cage box 4 at the lower level to the higher level, so as to facilitate the staff to replace the cage box 4 at the higher level. The first guide rail 26 and the first slider 25, the second guide rail 84 and the second slider 83 are used in coordination to ensure the stability of the cage box 4 during the movement. When it is necessary to supply water to the cage box 4, first control the motor 54 to stop running, so that the cage box 4 rotates to the specified position and then stops moving, and then the first frame 621 and the third frame 623 are driven to move to the specified position through the second electric guide rod 66. At this time, the first water outlet 632 and the second water outlet 642 are respectively aligned with the drinking water port on the cage box 4, and then the second electric guide rod 66 is started to drive the first water frame 61 to slide, so that the first water outlet 632 and the second water outlet 642 are respectively inserted into the corresponding drinking water port 42, so as to realize synchronous water supply processing for all cage boxes 4, and ventilate the isolation bag 7 through the air inlet 73 and the air outlet 74 on the isolation bag 7, thereby ventilating the cage box 4. The overall use is simple and convenient, which reduces the workload of the experimenter.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
