呼吸防护用品的人机工效学问题分析

呼吸防护用品符合人的形态与生理特征,才能保证其防护效果和舒适性。笔者从人体的面部形态与生理机能角度,分析了呼吸防护用品与人体的适配性,系统提出密合性、呼吸阻力、死腔、视野等呼吸防护用品的人机工效学问题。该论文取得的成果,对进一步丰富呼吸防护用品人机工效学研究内容,指导呼吸防护用品的设计与生产,提升我国呼吸防护用品的防护效果与核心竞争力,以期发挥积极的推动作用。

Analysis on the Problems of Protective Respirators Based on Ergonomics

Only such protective respirators in accordance with human being's figure and physiological features can ensure them effective and comfortable. Based on this view, this paper analyzes the suitability of protective respirators to human body, and systematically puts forward such ergonomic problems as seal, respiratory resistance, dead space and field of vision about protective respirators at the angle of human facial features and bio-mechanical characteristics of head and neck. This researching result will play an active role in enriching the ergonomic research of protective respirators, directing the design and production of protective respirators, and promoting the effect and competition of protective respirators in our country.
