Description

Technical Field

[0001] The utility model belongs to independent ventilation equipment for animal breeding, and relates to a cover opener for a purification cage for experimental animals and a purification cage for experimental animals. Background Art

[0002] Laboratory animals usually refer to animals that are artificially raised, have controlled microorganisms, have a clear genetic background or clear source, and are used for scientific research, teaching, production, verification, and scientific experiments. Purification cages are usually IVC independent ventilation cages, which use power and equipment to efficiently filter the air, and then continuously input clean airflow into a relatively independent and sealed cage through a pipeline. After sufficient and smooth circulation, the exhaust gas is output from the cage through another pipeline and discharged after high-efficiency filtration. The microenvironment indicators in the cage can reach or exceed the barrier environment standards, and are used in SPF-level laboratory animal breeding rooms, suitable for breeding SPF (specific pathogen-free)-level laboratory animals. It effectively ensures the safety of operators, animals, and the environment, and greatly saves operating costs.

[0003] The Chinese utility model patent with the announcement number CN220157297U discloses an experimental mouse cage that is convenient for replacing bedding, including a cage body, a partition net, a cage cover and a water feeder, wherein the cage body is provided with a partition net, the bottom of the cage body is used to place bedding, and the cage cover is sealed and installed above the cage body; a drawer for placing bedding is provided at the bottom of the cage body; a partition that can be pulled out is provided above the drawer, and the partition is used to drive the experimental mouse from the top of the drawer to the top of the partition. Through the utility model, a drawer for placing bedding is provided at the bottom of the cage body, which can facilitate the replacement of bedding, and a partition is provided above the drawer. After the partition is gradually inserted into the cage body, the experimental mouse will be expelled to the top of the partition, thereby realizing the isolation of the experimental mouse, avoiding moving the entire mouse cage, and there is no need to take out the mouse. The mouse can be directly isolated in the mouse cage and the bedding can be replaced, which is convenient and fast, reducing the risk of scientific researchers being bitten by mice, and also reducing unnecessary damage and stress to mice. The life window of the application is clamped with a sealing cover made of rubber or plastic, but the sealing cover is stuck in the experimental mouse cage, so it is more difficult for the experimenter to replace the sealing cover, resulting in reduced efficiency. At present, multiple protrusions are usually set on the surface of the sealing cover, but if the protrusions are too large, it will affect the stacking or layering of the experimental mouse cage (stacking or layering is to reduce the volume occupied by the experimental cage); if the protrusions are too small, the experimenter needs to spend a lot of effort to operate, which is especially unfriendly to female workers.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0019] This embodiment provides a laboratory animal purification cage, such as Figure 1 As shown, it includes a box body 1 and a cover body 2 detachably mounted on the top of the box body 1. Specifically, the circumferential surface of the box body 1 is provided with a snap-fitting protrusion, and the circumferential surface of the cover body 2 is provided with a snap-fitting protrusion 22, so that the box body 1 and the cover body 2 are snap-fitted. The cover body 2 has a cover body 21, and a life air window sealing cover 23 is threadedly mounted on the cover body 21 (at this time, the life air window sealing cover 23 is embedded in the cover body 21 through its own external thread). The life air window sealing cover 23 includes a cover body 231 and two lugs 232 formed on the outer surface of the cover body 231 and spaced apart, and the two lugs 232 are in the same plane passing through the axial center line of the cover body 231 (the height of the lug 232 is usually 1~3mm, and when it is higher than 3mm, it usually affects the stacking of cages), as shown in FIG. Figure 2 shown.

[0020] This embodiment also provides an experimental animal purification cage cover opener for unscrewing the life air window sealing cover 23. Figure 3 and Figure 4As shown, it includes a plate body 31, a handshake slot 32 provided on the plate body 31, and a plurality of slots 33 provided at the four corners of any circumference of the plate body 31 and extending inward, and the slots 33 are matched with the lugs 232. By providing the slots 33 at the four corners of any circumference of the plate body 31, when the user holds the cover opener, the slots 33 are matched with the lugs 232, and a large torque can be applied to the lugs 232 by turning the cover opener with force to rotate the lugs, which is conducive to reducing the effort required by the experimenter to open the cover and improving the efficiency of the experimenter to open the cover. Specifically, the surface of the cover opener opposite to the life window sealing cover 23 when in use is defined as the working surface, and these slots 33 are provided at the four corners of the working surface and extend to the inside of the plate body 31. There are two or four card slots 33; when there are two card slots 33, the two card slots 33 extend to two opposite sides of the plate body 31 respectively; at this time, the cover opener is located between the two lugs 232 so that the two lugs 232 are respectively inserted into the two card slots 33 to realize the rotation of the life window sealing cover 23. In this embodiment, there are four card slots 33, so both sides of the cover opener can be used. In this embodiment, the card slot 33 of the experimental animal purification cage cover opener has a depth of 4-5 mm and a length of 15-20 mm. The thickness of the plate body 31 is 10-16 mm, the length is 90-100 mm, and the width is 40-45 mm, and the length of the handshake slot 32 is 40-55 mm and the width is 20-25 mm. Example

[0021] This embodiment provides a cover opener for a laboratory animal purification cage, such as Figure 5 As shown, it is basically the same as the structure of the cover opener in Example 1, except that: two plug holes 33' are provided on any circumferential surface of the plate body 31 to match the lug 232; that is, two plug holes 33' are provided on the working surface to be recessed into the plate body 31, and the cross-sectional dimensions of the two plug holes 33' are slightly larger than the cross-sectional dimensions of the lug 232. Similarly, the depth of the plug hole 33' is 4-5 mm, and the length is 15-20 mm. Compared with the cover opener in Example 1, the disadvantage of such a cover opener is that it is only applicable to match the lug 232 of fixed position and size, and the scope of application is limited.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
