Abstract

The invention discloses a gas or aerosol mixing or dilution device, which comprises a mixing injection tube (6) and a mixing cavity (7), the first end of the mixing injection tube (6) is a first material inlet (1 ), the second end of the mixing injection tube (6) communicates with the mixing chamber (7); it is characterized in that it also includes a second material inlet (3), and the second material inlet (3) is A slit arranged on the wall of the mixing injection tube (6), the slit is formed by a first surface and a second surface parallel to each other. By setting the slit-shaped gas solvent inlet, the air intake is more uniform and stable, the dilution effect is better, the concentration after mixing or dilution is stable, and the distribution is uniform.

Description

technical field [0001] The invention belongs to the technical field of substance mixing and dilution, and in particular relates to a gas or aerosol mixing or dilution device. 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 models of COPD and the experimental research of its drug efficacy, the research of the influence of air pollutants on the respiratory system of animals, etc. Background technique [0002] At present, in various scientific researches related to inhalation toxicology, especially the research on some substances harmful to human health, such as PM2.5, etc., because it cannot be tested directly or first on humans, experimental animals are often used for inhalation. exposure evaluation. Therefore, animal exposure devices have a wide range of applications in industry, agriculture, medicine, environmental pollution and military scientifi...
