Abstract:
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 ensure the clinical treatment effect of them.
