Pneumoconiosis Rat Dust Inhalation Simulation Experiment Chamber

Abstract

The invention discloses a pneumoconiosis mouse dust inhalation simulation experiment chamber, which comprises a rat movable chamber, which is a rectangular transparent glass chamber, and the rat movable chamber is provided with an air inlet and an air outlet. The tops of each corner are equipped with automatic dust spraying devices, two of which are equipped with automatic drinking water and feeding devices, and the bottom of the other two automatic dust spraying devices are equipped with automatic teeth grinding devices; the automatic dust spraying devices include hanging chains , dust chamber, conical nozzle, conical slider and electric telescopic rod, the shell of the conical nozzle is surrounded by a conical dust spray cover and a bottom plate, and a return spring and a dust falling cone are also installed in the shell. It can simulate the process of periodic exposure and active inhalation of dust by underground workers in coal mines, better simulate the working environment of underground workers, and provide data support for exploring the pathogenic mechanism of dust in coal mining environments.

Description

technical field [0001] The invention belongs to the technical field of coal worker pneumoconiosis animal simulation experiments, and mainly relates to a dust active inhalation simulation experiment device. Background technique [0002] In the process of coal mining, a large amount of dust is produced, which pollutes the roadway environment. Workers inhale dust for a long time and cause pneumoconiosis, which seriously threatens the occupational safety and health of workers. Underground coal mine workers suffering from pneumoconiosis due to long-term exposure to dust is a common problem at home and abroad. Moreover, there are few relevant experiments on workers exposed to dust, and dust will cause great harm to workers' bodies, which not only seriously affects the physical and mental health of workers, but also restricts the development of underground coal mining. [0003] The investigation of the current situation of prevention and control of occupational diseases in coal mi...

AI Technical Summary

Problems solved by technology

However, due to the limitations of the experiment, it is difficult to carry out the dust inhalation experiment on coal miners, and thus the follow-up pathological research cannot be carried out

At present, some researchers have begun to use pneumoconiosis rats to simulate the impact of dust on human body functions during the process of human inhalation of dust, but most of the methods are to let pneumoconiosis rats be passively exposed to dust, which cannot well simulate the process of human exposure to dust. Therefore, the follow-up research work cannot be carried out effectively
