Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0022] Such as figure 1 As shown, a whole-body exposure chamber for animals includes a cylindrical cavity in the middle section, a conical cavity at the upper end, and a conical cavity at the lower end; an aerosol inlet 10 is arranged on the top of the conical cavity at the upper end, and the aerosol inlet 10 is connected with the experimental The aerosol generator of the device is connected, and the aerosol inlet 10 is connected to an atomizing diffuser 20, and the atomizing diffuser 20 is used to diffuse the aerosol entering the animal's whole body exposure chamber. The structure has no vertical corner design, so the flow of aerosol in the exposure chamber has no influence of corners. The exposure chamber cavity with this structure has a more unifo...

Abstract

The invention provides a whole body exposure chamber for animals. The whole body exposure chamber comprises a middle cylindrical cavity, an upper-end conical cavity and a lower-end conical cavity, and an aerosol inlet is arranged in the top of the upper-end conical cavity and connected with an atomization diffuser which is used for diffusing aerosol entering the whole body exposure chamber for animals. Since the whole body exposure chamber comprises the middle cylindrical cavity, the upper-end conical cavity and the lower-end conical cavity, the exposure chamber of the structure is more uniform in distribution of the internal aerosol and more conformable to international testing standards in size. No vertical corner is designed in the structure, so that the aerosol flows in the exposure chamber without influence of the corners.

Description

technical field [0001] The invention relates to the field of animal inhalation toxicology experiments, in particular to an animal whole body exposure chamber for inhalation toxicology. 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 rete...
