Effect of the microenvironment of powered air-purifying medical protective hood on the body's physiological parameters / 医疗卫生装备

ABSTRACT

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.
