摘要
目的:为实现长航时空运后送呼吸道传染病病员过程中对医务人员保护性隔离并解决其饮水和能量补充等问题,设计一种适合长航时空运后送使用的医用正压防护服。方法:该防护服采用连体式结构,面料选用水刺无纺布,头部和前胸位置采用聚对苯二甲酸乙二醇酯防雾材料,穿脱部位选用拉链+自粘方式进行密封处理。该防护服配备便携式正压送风装置、机载集中正压送风装置和监测预警装置。其中,便携式正压送风装置固定在防护服背后腰间,机载集中正压送风装置在市场现有正压送风机的基础上进行改进,监测预警装置主要对风机送风量、电池电量和防护服内压力进行监测。结果:该防护服防护效果较好,且在休息状态下清洁新风供给不受时间限制,可以释放3个活动空间,方便医务人员进行水分和能量补给。结论:该防护服能够持续提供清洁、舒适的微环境,可满足长航时空运后送呼吸道传染病病员时医务人员防护、补充水分和能量的需要。
Objective To develop a medical positive pressure protective suit for long-voyage aeromedical evacuation to realize protective isolation and drinking water and energy supply for medical personnel during long-voyage aeromedical evacuation of respiratory infectious disease patients.Methods The medical positive pressure protective suit had a one-piece structure,with its main part made of hydroentangled non-woven fabric,head and forebreast parts made of amorphous polyethylene terephthalate anti-fog material and wearing-and taking-off parts sealed with zipper and autohesion,which was equipped with a portable positive pressure air supply device,an airborne centralized positive pressure air supply device and a monitoring and warning device.The portable positive pressure air supply device was fixed in the back of the suit at the waist,the airborne device was made by modifying the commercially available positive pressure air supply fan,and the monitoring and warning device monitored the air supply volume of the fan,the battery power and the pressure inside the suit.Results The suit behaved well in protection,clean fresh air supply without time limitation and facilitating hydration and energy replenishment of medical personnel by forming three activity spaces.Conclusion The suit developed can continuously provide a clean and comfortable microenvironment,meeting the requirements of medical personnel for protection and hydration and energy replenishment during long-voyage aeromedical evacuation.
