Biological safety type cage changing platform

Abstract

The invention discloses a biological safety type cage changing table. An operation cavity is formed in a cage changing table body, a workbench is arranged at the bottom of the operation cavity, a ventilation channel exists between the side wall of the operation cavity and the side wall of the cage changing table body, and an air supply efficient filter, an air collection chamber and an air exhaust efficient filter are sequentially arranged at the top of the operation cavity from bottom to top; a dirty cage inlet is formed in the side, close to the cage changing table body, of a dirty cage box collecting barrel, and a sealing door is arranged at the joint of the dirty cage box collecting barrel and the cage changing table body; a new cage disinfection box comprises a box body, a liquid storage box, a first air-tight sealing door and a second air-tight sealing door; and a new cage inlet is formed in the connecting position of the box body and the cage changing table body, the new cage inlet communicates with the interior of the cage changing table body, the new cage inlet is connected with the first air-tight sealing door, the new cage outlet is further formed in the surface of the box body, and the second air-tight sealing door is fixed to the new cage outlet. According to the biological safety type cage changing table, an operator cannot be hurt, disinfection is thorough, and environmental pollution and virus diffusion cannot be caused.

Description

technical field [0001] The invention relates to the technical field of cage changing platforms, and more specifically relates to a biologically safe cage changing platform. Background technique [0002] The biosafety IVC cage is a kind of feeding used in high-level virus animal experiments. Since the cage needs to be cleaned regularly during the feeding process, the experimental animals need to be changed to ensure the continuous and smooth progress of the experiment. At present, the cage changing operation of IVC cages is carried out on ordinary clean benches or cage changing workstations or in ordinary clean areas. When replacing the cage, it is easy to pollute the surrounding environment and the operator, endangering the life and health of the operator. [0003] There are still some problems when the existing cage changing station or cage changing workstation is used to change the IVC cages for high-level virus experiments: [0004] 1. The protection of the environment ...

AI Technical Summary

Problems solved by technology

[0004] 1. The protection of the environment and operators during the cage changing operation is not thorough enough, which is likely to endanger the life and health of operators;

[0005] 2. After the cage change is completed, the operation area of ​​the cage changing platform or the cage changing workstation is a polluted area without self-disinfection function, which will cause environmental pollution and spread of viruses after shutdown;

[0006] 3. Failure to isolate and disinfect the replaced old cages in time will pollute the environment and cause the spread of the virus;

[0007] 4. Since the operation area during the cage change process is a polluted area, the surface of the new cage box has been polluted after the cage change is completed, and the surface cannot be isolated and disinfected in time, which will pollute the environment and cause the spread of the virus;

[0008] 5. After the cage is changed, due to the existence of live animals in the new cage, the surface disinfection of the cage is limited, and it is easy to cause environmental pollution and virus spread due to incomplete disinfection.
