摘要
目的解决传统医用气体管道系统在维护关键控制节点时遇到的风险。方法采用冗余设计方法,将医用气体管道系统从气源敷设双主管到医疗建筑,通过双立管到护理单元,采用U型管道结构,用维修隔离阀将气体终端划分成较小区域。结果此系统增加了管道结构的复杂度,增加了15%～30%的前期投入成本,但提高了系统的可靠性,降低后期维护费用和医疗维护风险成本。在管道分配系统中,任何部位出现故障需要维护时,气体终端的连续供气不受影响,或仅影响几间病房。结论适用于规模较大的医院和局部生命支持区域。
Objective To solve the high risk when maintaining the key node of medical gas pipeline systems in large scale hospitals.Methods Adopting redundancy design method,medical gas pipeline system could transfer the air across double main pipes to medical building,through the double riser pipe to nursing unit,maintenance isolation valve,using U pipe structure,also could divide gas terminal into smaller area.Results On one hand,the medical gas pipeline system based on redundancy increases 15%～30% cost of installation,and makes the structure of pipeline complex,on the other hand,it improves the reliability of this system and reduces the follow-up maintenance cost and risk.It can also guarantee the continuous gas supply of terminal not be affected when fixing the failure,or only effect several wards.Conclusion The pipeline system is suitable to large scale hospitals and lifeline support areas.
