Individual dustproof respirator efficiency test experiment device and method

Abstract

The invention discloses an individual dustproof respirator efficiency test experiment device and method, and relates to the technical field of pneumoconiosis prevention and treatment. The experiment device comprises two animal experiment cavities, a connecting pipe and a humanoid respiration simulator, wherein the two animal experiment chambers are a first experiment chamber and a second experiment chamber respectively, and a dust production system is arranged in the first experiment chamber; an individual dustproof respirator filter material is arranged in the connecting pipe and used for filtering dusty airflow flowing through the connecting pipe. The influence of dust on the lung health of a mouse and the dustproof effect of an individual dustproof respirator can be displayed more accurately and visually; experimental results are presented by comparing lung anatomy and pathological sections of the mouse, so that strong visual impact is caused to people, and a greater warning effectis achieved; and meanwhile, in the experiment process, according to the fact that the respiration of the human body is more similar to sinusoidal circulation flow, the accurate simulation of the respiration of the worker during operation is realized by utilizing the humanoid respiration simulator technology, and the experiment result is more accurate.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment of pneumoconiosis, in particular to an experimental device and method for testing the effectiveness of an individual dust-proof respirator. Background technique [0002] With the rapid development of industry, workplaces and positions that produce dust in engineering construction, gold mining, quartz processing and gem processing industries continue to appear, and the number of people exposed to dust has greatly increased. However, the operators of some enterprises neglect labor hygiene management and invest very little in protection funds, resulting in poor working environment and serious dust occupational hazard situation. Among them, coal mining enterprises are the most serious dust hazards. There are generally high-concentration dust environments where the dust concentration seriously exceeds the occupational health standards. The respiratory protection problems of dust-expose...

AI Technical Summary

Problems solved by technology

Therefore, in actual work, workers are often unwilling to wear respiratory protective equipment, and feel that wearing it is troublesome, uncomfortable after wearing it, inconvenient to work after wearing it, and it doesn’t matter whether they wear it or not, etc.

Even where protective masks are mandatory, workers are reluctant to wear them

In the existing research, there is also a lack of scientific experiments to prove that wearing a personal dust-proof respirator can effectively prevent the occurrence of pneumoconiosis
