摘　　要：目的:分析复杂环境下不同型号频谱治疗仪质量检测结果,以提高其临床使用的可靠性,并为医疗机构选择适应不同环境的频谱治疗仪提供参考。方法:选择4款不同品牌的频谱治疗仪(品牌A、B、C、D),分别模拟寒冷、炎热、湿热和盐雾地区的环境,对频谱治疗仪展开低温储存、高温储存、湿热储存以及盐雾检测试验。依据国家标准《医用电器环境要求及试验方法》《军用装备实验室环境试验方法第11部分:盐雾试验》对检测试验后的频谱治疗仪外观功能和温度控制等质量检测结果进行分析。结果:外观功能检测中,品牌A、品牌B和品牌C在低温储存、高温储存、湿热存储和盐雾试验之后其外观功能正常,品牌D仅在盐雾试验后表面出现明显锈蚀。温度控制检测中,4款频谱治疗仪在低温储存、高温储存、湿热存储和盐雾试验后其温度不均匀度的误差均≤10%;品牌B和品牌D已知辐射器表面温度标称值,其误差为-10%~+10%,品牌A和品牌C未知标称值,故无法进行分析。结论:在复杂环境下对频谱治疗仪进行质量检测分析,可提高频谱治疗仪的临床使用可靠性,并可为不同环境地区医疗机构选择适用的品牌型号,从而保障临床治疗效果。Objective:To analyze the results of quality detection of different brands of spectrum therapy apparatuses in complex environment,so as to improve the reliability of that in clinical use and to provide reference for medical institutions in selecting spectrum therapy apparatus that suits to different environments.Methods:A total of 4 different brands of spectrum therapy apparatuses(brand A,B,C,D)were selected,and the environments of cold,hot,wet and heat,and salt fog area were respectively simulated.The detection tests of low temperature storage,high temperature storage,wet and heat storage,and salt fog were conducted on the spectrum therapy apparatuses.According to the national standard"Environmental requirements and test methods for medical electrical equipment"and"Laboratory environmental test methods for military materiel Part 11:salt fog test",the results of quality tests of appearance function and temperature control of the spectrum therapy apparatuses after the test were analyzed.Results:In the test of appearance function,the appearance functions of brand A,brand B and brand C were normal in the tests of low temperature storage,high temperature storage,wet and heat storage,and salt fog,and brand D only showed obvious surface corrosion after salt fog test.In the test of temperature control,the errors of the temperature non-uniformity of the 4 spectral therapy apparatuses were less than 10%after the tests of low temperature storage,high temperature storage,wet and heat storage,and salt fog.The error ranges of brand B and brand D were between-10%and+10%due to the marked values of the surface temperatures of radiation devices of them were known,while those of brand A and C could not be analyzed due to the marked values of them were not known.Conclusion:The analysis on the quality detection of spectrum therapy apparatuses in the complex environment can improve the reliability of that in clinical use,and can choose the suitable brand and model for medical institutions at differently environmental regions,so as to
