Embodiment Construction

[0025] Such as figure 1 As shown, the fine particle inhalation device for constructing an animal injury model according to the present invention includes a dust smoke generator and a dust smoke inhaler connected in sequence, wherein the dust smoke generator is used to form uniform smoke, and the dust smoke inhalation The device was used to inhale the dust and fumes of the poisoned animals to construct the injury model.

[0026] The dust and smoke generator includes a support 15, and a dust storage bin 3 arranged on the support 15 for storing smoke and dust, a constant speed regulating device that can adjust the amount of smoke and dust output, and is connected with the dust and smoke inhaler to discharge the dust and smoke. The dust and smoke generation pipeline 5 delivered to the dust and smoke inhaler. The constant-speed regulating device adjusts the dust output of the dust to ensure uniformity, and then the dust and smoke are transported to the dust and smoke inhaler throu...

Abstract

The invention belongs to the technical field of animal model building, and particularly relates to a fine particle inhaling device for building an animal injury model. The fine particle inhaling device for building the animal injury model comprises a dust smoke generator, a dust inhaling device and a dust smoke recovering device, wherein the inhaling device can form stable fine particle inhaling environment with controllable concentration so as to build the animal injury model for simulating a dust-haze environment; meanwhile, the inhaling device can achieve the goal of performing stable fine particle inhaling on various animals at the same time in one step; various particles can even be used for realizing the absorption contamination. The inhaling device has the advantages that the structure is simple; the operation is easy; the animal absorption contamination effect is more stable and more uniform; the recovering device is installed, so that the particle recovery can be realized; the secondary pollution on environment and the injury on the experiment personnel are avoided.

Description

technical field [0001] The invention belongs to the technical field of animal model building, and in particular relates to a fine particle inhalation device for building animal injury models. Background technique [0002] PM2.5, also known as inhalable lung particulate matter, refers to particulate matter with an aerodynamic diameter less than or equal to 2.5 μm in the total suspended particulate matter in the atmosphere. Although PM2.5 is only a small component in the earth's atmospheric composition, it has an important impact on environmental quality, air visibility and human health. Existing studies have shown that particulate matter stays in the atmosphere for a long time, can be transported over a long distance, and has a large impact range. The smaller the particle size, the greater the harm to human health. There is a negative correlation with diameter: particles with a diameter of 10 μm are usually deposited in the upper respiratory tract, while those below 2 μm can...
