Experimental animal negative pressure isolator and using method thereof

Abstract

The invention provides an experimental animal negative pressure isolator and a using method thereof. The isolator mainly comprises a living module and a manure module, one side of the living module is provided with a transmission window, a fan is arranged at the upper end of the living module, a fresh air inlet is formed in the fan connected with an external efficient filter, a clamping groove is formed in the upper port of the manure module, the bottom of the living module is connected with the clamping groove of the manure module in a plugged mode, the front end of the living module is provided with first operation gloves, the front end of the manure module is provided with second operation gloves, the bottom of the manure module is connected with a manure cleaning device, four corners of the bottom of the manure module are connected with a base support, and the bottom of the base support is further provided with a brake roller. The experimental animal negative pressure isolator is simple in structure, convenient to use and capable of increasing experimental efficiency, the problem is eradiated that pathogens are exposed at the moment animal excrement is removed from the manure module, the probability of overflow of pathogenic microorganisms is reduced, the usage amount of plastic bags is reduced at the same time, and the environmental protection is promoted.

Description

[0001] Technical field: [0002] The invention relates to the field of isolators, in particular to a negative pressure isolator for experimental animals and a use method thereof. [0003] Background technique: [0004] At present, the negative pressure isolator for experimental animal breeding is used for high-standard live animal experiments to ensure that experimental animals are reliably isolated from the outside world, and can conveniently carry out feeding, research, excrement and corpse disposal. [0005] In the process of animal experiments, it is often necessary to inoculate and collect tissues under non-killing conditions. Because there is no partition device inside the traditional isolator, the traditional method is to use an oil-based pen to distinguish between treated and untreated chickens by dyeing their hair color. Both increase the workload, and the identification result is not sure. [0006] In the experiment, experimental animal welfare can affect the results...

Problems solved by technology

However, there is a potential danger of a large number of pathogens being exposed at the moment of leaving the dung hatch

[0009] In addition, the seams between the animal living compartment and the dung compartment of the traditional positive pressure isolator and the positive pressure to negative pressure isolator need to be sealed with scotch tape, but the adhesive tape is not completely tight enough and it is easy to be glued over time, causing the isolator to leak. Potential hazards of pathogenic microorganisms spilling out with aerosols in animal infection experiments
