Embodiment Construction

[0027] 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.

[0028] like figure 1 and figure 2 As shown, the embodiment of the present invention provides a gas or aerosol mixing or dilution device, including a first gas channel and a sleeve arranged on the periphery of the first gas channel, and a second gas channel is formed between the sleeve and the first gas channel. material channel. The first gas is air, and the second substance is aerosol. This device is mainly used in the dilution of aerosols and in inhalation toxicology experiments. This protocol can also be used for the mixing of two substances. Such as the mixing of gas and gas.

[0029] The first gas channel includes a gas inlet 1, a gas inlet pipe 2, a gas static pressure chamber 4 and a static pressure chamber outlet 5 connected in sequence,...

Abstract

The invention discloses a gas or aerosol mixing or diluting device, which comprises a first gas passage, and the first gas passage includes a gas inlet (1), a gas inlet pipe (2) and a gas static pressure chamber connected in sequence (4) and the static pressure chamber outlet (5), characterized in that the static pressure chamber outlet (5) is a gap provided on the wall of the gas static pressure chamber (4). By setting the outlet of the slit-shaped static pressure chamber, the gas entering the mixing place is more uniform and stable, the mixing or 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...
