摘要
目的:为了满足伤病员高压氧就地治疗、转运的需求,设计一种高压氧舱急救车。方法:该高压氧舱急救车以YJ2080轮式装甲车为车载底盘,并集成舱体、气源、氧源、控制系统、电源等部件。其中,舱体设计为3层复合结构,外层为高强度金属框架,内层为由聚氨酯材料制成的外缚尼龙抗压带的囊体,舱体与车厢之间填充保温材料;气源设计采用“无油空气压缩机+储气瓶+减压器”方案;氧源设计采用“20 L制氧机+氧气增压泵+40 L氧气瓶”方案;控制系统选用EX2N-100HA系列触摸屏可编程逻辑控制器(programmable logic controller,PLC)一体机作为控制器;电源选用ACD-15.0DR/48-H发电机系统。结果:该高压氧舱急救车在治疗压力为1.3、1.6、1.8 ATA(1 ATA=0.1 MPa)时均能稳定控制舱内压力,在低氧气体积分数模式和高氧气体积分数模式下舱内氧气体积分数均能控制在要求范围内,且紧急减压时间均控制在60 s以内。结论:该高压氧舱急救车机动性强,能够有效满足伤病员高压氧就地治疗、转运的需求。
Objective To design a hyperbaric oxygen chamber ambulance to meet the requirements for on-site hyperbaric oxygen treatment and transport of casualties.Methods A hyperbaric oxygen chamber ambulance was formed based on a YJ2080 wheeled armored vehicle,which had the components of a chamber,a gas source,an oxygen source,a control system and a power source.The chamber had a 3-layer composite structure,with a high-strength metal frame in the outer layer,a capsule made of polyurethane material bound with nylon pressure-resistant tape in the inner layer and a layer of thermal insulation material filled between the chamber and the vehicle;the gas source was composed of the oil-free air compressor,gas cylinder and pressure reducer;the oxygen source was made up of the 20 L oxygen generator,oxygen booster pump and 40 L oxygen cylinder;the control system involved in an EX2N-100HA series touch screen programmable logic controller(PLC)all-in-one(AIO);an ACD-15.0DR/48-H generator system was used as the power source.Results The hyperbaric oxygen chamber ambulance could stably control the chamber pressure when the therapeutic pressure was set as 1.3,1.6 and 1.8 ATA(1 ATA=0.1 MPa),the volume fraction of oxygen in the chamber could be limited within the required range under the low oxygen volume fraction mode and high oxygen volume fraction mode,and the emergency decompression time could be restrained within 60 s.Conclusion The hyperbaric oxygen chamber ambulance behaves well in maneuverability,and can be used for on-site hyperbaric oxygen treatment and transport of casualties.
