摘要
采用环境生理学测量方法,对送风过滤式医用防护头罩进行了人体工效学试验,旨在为该装备的性能和结构设计及其适合人体生理特点的程度提供科学的依据和评价。一是分析了不同给气流量条件下头罩内环境氧气、二氧化碳、温度和湿度指标变化;二是通过测定受试者的心率和血氧饱和度生理参数变化,考察对头罩的适应能力;三是利用国际通用的疲劳感知分级表RPE对受试者进行考察并填写调查表。结果显示,在适宜给气流量条件下该装备能够满足受试者的生理需求。
Environmental physiological method adopted, the ergonomic experiment is to seek the best parameter of the protective hood structural size, on which the structure design of the protective hood will be based, through the analysis of the organic relationship between the microenvironment of power air-purifying medical protective hood and the body's physiological characteristics. The changes of such indexes due to different air currents are analyzed as the oxygen, carbon dioxide, temperature and humidity in the microenvironment. The changes of testees' physiological parameters and their responses to psychological loads and body strengths are paid attention to. The results show the hood can meet the testees' demands with proper air current.
