Description

Technical Field

[0001] The utility model relates to the technical field of poisoning experiments, in particular to an exposure poisoning cabin. Background Art

[0002] Equipment that exposes the respiratory system to toxicity by inhaling the test substance through the respiratory tract is collectively referred to as an inhalation exposure system. According to the degree of exposure of the animal to the test substance, it is divided into an oral and nasal inhalation exposure system and a whole-body inhalation exposure system. During the animal exposure room experiment, the former only exposes the mouth and nose to the test substance environment, thereby only toxicating the respiratory system; the latter will expose the whole body of the small animal to the test substance environment to complete the respiratory system toxicity.

[0003] The animals in the whole body inhalation exposure system are exposed to the test substance environment, so generally in a larger poisoning chamber, the animals can move freely, the real poisoning environment can be simulated, and the behavioral effects of animal toxicology can be recorded. However, due to the large poisoning chamber, the system occupies a lot of space and the amount of test substance required is also large, and the operating cost of the equipment and the experimental reagents are high. In addition, if the test substance has the characteristics of being toxic by inhalation through the animal skin or hair, it will interfere with the experimental results.

[0004] The oral and nasal inhalation exposure system restricts the animal's activities through an animal holder, directly connects the animal's mouth and nose to the aerosol pipe of the test substance, and exposes the animal's respiratory system only through the mouth and nose. In this way, the consumption of the test substance is greatly reduced and the possibility of animal skin and hair contamination is avoided, while the requirements for experimental space are also reduced. According to the different experimental animals, it can be divided into small animal oral and nasal exposure system and large animal oral and nasal exposure system, among which beagles are the representatives of large animals. However, when animals are given drugs through the mouth and nose, drug aerosols are easy to leak into the laboratory, which may cause damage to the health of the experimenters and do not meet the requirements of occupational health.
