埃博拉疫情防控正压生物防护服研究

目的 :研究正压生物防护关键技术,研发用于埃博拉个人防护的系列正压生物防护服。方法 :采用聚氨酯双面贴膜研究正压生物防护服复合面料,设计全身式和半身式正压生物防护服结构;采用高性能风机和控制系统,研究电动送风系统;参照相关标准对系列正压生物防护服进行安全性评价。结果:研制的聚氨酯复合面料复合正压生物防护服符合防护要求,研制了系列正压生物防护服,防护服正压差>150 Pa,噪音<70 d B,连续工作时间>4 h,对0.3μm粒径气溶胶整体防护因子>100 000,整体防液体渗透性能满足标准GB 24539—2009要求。结论:研制的系列正压生物防护服可以应用于埃博拉等烈性传染病的医护人员高水平个人防护。

Research of positive-pressure bio-protective suit for Ebola disease

Objective To study the key techniques of positive-pressure protection and series of suits for Ebola disease.Methods The suit had composite fabric made of double-side filmed polyurethane, an electric blower system made of high-performance blower and control system as well as an one-piece and two-piece structure. Safety evaluation of the suit was carried out according to standard related. Results The suite could meet the desired requirements, with the positive pressure difference more than 150 Pa, noise less than 70 d B, continuous operating time more than 4 h and general protection factor more than 100 000 against 0.3 μm aerosol particles. The anti-seepage performance against liquid accorded with GB 24539—2009. Conclusion The suit can be used for the protection of medical staffs against the fulminating infectious diseases such as Ebola disease.
