Technical Field

[0001] The present application relates to the field of cages, and in particular to a cage for small animal transmission infection experiments. Background Art

[0022] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiment is only one embodiment of the present invention, not all embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Unless otherwise defined, technical or scientific terms used in the present invention shall have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs.

[0024] This embodiment provides a cage for small animal transmission infection experiments.

[0025] Reference Figure 1 and Figure 2A cage for small animal transmission infection experiments includes a first cage 1 with a cage cover, a second cage 2, and a third cage 3. The first cage 1 is used to house infected animals and healthy animals, i.e., infected animals and healthy animals are mixed in the first cage 1 for conducting contact infection experiments; the first cage 1 is connected to an air inlet 11.

[0026] The second cage 2 is used to place healthy animals and is integrally formed with the first cage 1. The first cage 1 and the second cage 2 are connected, and the connection is isolated by two layers of partition nets to conduct droplet transmission infection experiments in the second cage 2.

[0027] The third cage 3 is also used to house healthy animals and is connected to the second cage 2 via a transmission pipe, allowing aerosol transmission experiments to be conducted within the third cage 3. The third cage 3 is also connected to an air outlet 31, which can be connected to a fan to accelerate the circulation of aerosols through the first cage 1, the second cage 2, and the third cage 3, thereby improving the efficiency of the transmission experiment.

[0028] To ensure a single route of infection for animals within the second and third cages 2 and 3, multiple partitions 4 are evenly spaced vertically along their lengths. These partitions 4 form animal isolation chambers, each capable of housing a single animal. The partitions 4 are detachably connected to the second and third cages 2 and 3, using snap-on or threaded connections to adjust the size of the isolation chambers to the size of the animals.

[0029] A water trough 5 is provided between the first cage 1 and the second cage 2, and a water trough 5 is also provided on the third cage 3. The water trough 5 is connected to the first cage 1, the second cage 2 or the third cage 3 through a water feeding pipe; at the same time, a cover frame 6 for covering the experimental animals is provided in the first cage 1, the second cage 2 and the third cage 3, and a food trough 61 is provided on the cover frame 6 to ensure the normal diet of the experimental animals.

[0030] In order to facilitate the transportation of the cages, handles 7 are provided on both sides of the first cage 1 , the second cage 2 and the third cage 3 .

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
