Detailed Description
In order to make the present invention easier to understand, the following will further illustrate specific embodiments of the present invention.
A device for experimental animal anesthesia and euthanasia comprises a box body 1 and a box cover 2.
The box body 1 is in a square box shape with an opening at the upper end and is made of glass or acrylic plates made of transparent materials, a plurality of vertical sliding grooves 4 used for fixing the partition boards 3 are formed in the lower portion of the inner wall of the box body 1, and the partition boards 3 are fixed through the sliding grooves 4. The height of the partition board 3 can be designed according to actual needs, so that the animal can be effectively partitioned to observe the state of the animal.
The box cover 2 comprises a fixed layer 5 and a movable layer 6, the fixed layer 5 can completely cover the opening of the box body 1, and a rubber pad for sealing is arranged at the contact position of the fixed layer 5 and the opening edge of the box body 1. The movable layer 6 is positioned below the box cover 2, and the shape and the size of the movable layer are matched with the inner wall of the box body 1. The movable layer 6 is connected with the fixed layer 5 through the hydraulic telescopic device 7, so that the movable layer 6 can move up and down in parallel along the inner wall of the box body 1 under the action of the hydraulic telescopic device 7.
