摘要/Abstract

摘要：

针对医护人员长时间穿着医用防护服工作导致体感闷热潮湿、疲劳增加、工作效率降低的问题,设计真人穿着试验,分析人体的热生理和主观感觉参数,从医用防护服的热湿性能角度分析对人体疲劳度的影响。试验结果表明:搭配短袖套装的防护服热湿舒适性最好,搭配长袖厚款套装的防护服热湿舒适性最差;穿着不同热湿性能的防护服在进行不同强度的运动中对人体疲劳度的影响不同,穿着防护服在静坐状态下,人体疲劳程度差异较小;在低、中、高强度运动和恢复状态下,防护服热湿舒适性越差,人体疲劳程度越深;平均皮肤温度、心率、能量代谢当量参数与主观疲劳感呈显著相关性,通过回归分析得到疲劳感与心率的模型,心率可以反映人体的疲劳程度。

Abstract:

It has been a noted problem that medical staff wearing medical protective clothing for a long time would feel hot and humid, leading to fatigue and low work efficiency. A research based on human wearing experiment is carried out. Through the analysis of human thermal physiology and subjective fatigue parameters, the influence of the thermal-moist comfort performance of medical protective clothing on human fatigue was analyzed. The results show that the thermal-moist comfort of protective clothing with short sleeves is the best, and that with long sleeve and thick suit was the worst.Wearing protective clothing with different thermal-moist comfort performance has different effects on human fatigue under different exercise intensity. Wearing protective clothing in the state of sitting, the difference of human fatigue degree is small. Under the conditions of low, medium and high exercise intensity and recovery, it was shown that the worse the thermal-moist comfort of protective clothing, the deeper the fatigue degree of human body. The average skin temperature, heart rate and metabolic equivalent of energy were found to be significantly correlated with subjective fatigue. Regression analysis was used to get the model of fatigue and heart beat rate, which reflects the fatigue degree of human body.

Key words: medical protective clothing, thermal-moist comfort, metabolism, mean skin temperature, fatigue
