Description

Experimental animal padding transfer device

Technical Field

The utility model belongs to the field of experimental animal auxiliary equipment, and particularly relates to an experimental animal padding transfer device.

Background

The experimental animals commonly used in the clinical research of the traditional medicine are non-human primates, mice, rats, dogs, rabbits, pigs and the like. Laboratory animals such as mice, rats, rabbits and the like must be kept with padding, which is commonly used as shavings or corncobs, which have water absorbability and require autoclaving before use. Padding is used because rodents prefer to level the bottom of the cage with padding. For animals such as mice, rats, rabbits, etc., direct contact with litter increases the chances that they will express natures, such as searching, digging, and nesting.

The pad can absorb the moisture in the excrement of the experimental animal, so that the pad is convenient to clean; in addition, the method can keep the microenvironment dry, inhibit the propagation of microorganisms by absorbing moisture by the padding, prevent the microorganisms from decomposing urea in excrement to generate ammonia and carbon dioxide, and further prevent the ammonia and harmful bacterial toxins in the microenvironment from gathering, but if the ammonia in the microenvironment is increased or the padding is saturated in absorption, the continuous use can cause respiratory damage and eye problems.

The padding contains a great amount of ammonia gas because of animal manure. Studies have shown that when ammonia concentration reaches 4 mL/L (about 0.003 mg/m 3), eyes are stimulated, and workers are exposed to environments with high ammonia concentration for a long time, so that symptoms such as cough, allergy and the like can appear. Therefore, it is necessary to collect the padding in the animal room at intervals, then transport the padding out of the laboratory area through the transfer car and dispose of the padding in an environmentally safe manner, and finally replace the padding with new padding.

In the prior art, for excrement, padding and biological waste generated in animal houses, plastic bags or other bags are generally adopted to collect the mixture, and then the waste such as the padding is manually and directly conveyed to the outside of a laboratory. During the process of collecting padding, loading or unloading the padding, workers often need to be in close contact with the padding and stay in an animal house for a long time, and leakage, dissipation and the like occur when the plastic bags are broken. These conditions all lead to the continuous diffusion of odors into the animal housing environment, which can cause serious discomfort to operators, laboratory personnel and laboratory animals, contaminating the clean laboratory environment.
