Abstract

The invention provides a whole body exposure system for animals. The whole body exposure system comprises a whole body exposure chamber, an aerosol generation system, a sampling system, a waste gas recycling and treating system and a control system; the whole body exposure chamber is used for placement of animals for toxicity experiment; the aerosol generation system is communicated with the whole body exposure chamber and used for generating aerosol for inhalation toxicity experiment; the sampling system is used for collecting concentration of the aerosol in the whole body exposure chamber; the waste gas recycling and treating system is communicated with the whole body exposure chamber and used for recycling and treating waste gas generated by the animals and excessive aerosol; the control system is used for regulating the concentration of the aerosol in the whole body exposure chamber in the experiment process. The concentration of the aerosol in the whole body exposure chamber is detected through the control system and the sampling system, automatic control of the whole body exposure system is realized, accurate control on the concentration of the aerosol in the whole body exposure chamber is realized, and requirements of experiments are met. The whole body exposure system with the automatic control system is high in automation degree and experiment accuracy.

Description

technical field [0001] The invention relates to the field of animal inhalation toxicology experiments, in particular to an animal whole body exposure system. It can be used for the safety evaluation of inhalation toxicology drugs, the inhalation experiment research of acute toxicity of pesticides, the construction of various animal disease models and the experimental research of their drug efficacy, the research of the influence of air pollutants on the animal respiratory system, etc. Background technique [0002] Inhalation toxicology is a science that studies the various conditions, laws and mechanisms of the occurrence, development and elimination of the toxic effects of inhalable substances on the body, as well as the risk assessment of inhalable substances. His professional research contents mainly include: the physical and chemical properties of various substances in the air; the basic biology of the respiratory tract; the deposition and retention of inhaled substances...
