Résumé
In 2003, the responsibility of radiation source safety supervision was redivided and transferred from the health department to the environmental protection department. After the promulgation and implementation of the Rule on the Administration of Radiodiagnosis and Radiotherapy in 2006, due to the incorporation of a large number of medical practice supervision rules, the radiation health supervision of medical institutions has evolved into the radiodiagnosis and radiotherapy supervision. In the past 16 years, radiation, occupational health supervision, and medical practice supervision have not been well integrated, and there are many legal problems in radiodiagnosis and radiotherapy supervision. The regulation rules of environmental protection, metrology, and other relevant departments on radiation sources and radiation devices have been constantly changing, resulting in overly complex regulatory requirements on radiodiagnosis and radiotherapy, which increases the burden of medical institutions. This paper reviews the historical evolution and legal system changes of radiodiagnosis and radiotherapy supervision, analyzes the problems and challenges faced by the relevant regulatory departments, and proposes ways to improve the supervision system.
Résumé
Objective To enhance the verification coverage of mercury sphygmomanometer by PDCA.Methods PDCA cycle principle was used to determine the causes for the low verification coverage of mercury sphygmomanometer,and some countermeasures were put forward accordingly.Results The involvement of PDCA increased the verification coverage of mercury sphygmomanometer,standardized mercury sphygmomanometer metrological verification,and thus ensured the quality of mercury sphygmomanometer for clinical use.Conclusion PDCA cycle principle can improve hospital metrological device management effectively,and thus is worthy promoting practically.
Résumé
Objective To improve the coverage rate of medical equipment metrological verification to ensure medical equipment safety and efficiency.Methods PDCA cycle was used to analyze the main problems in medical equipment metrological verification from the aspects of personnel,institution,management and flow,and the solutions were put forward accordingly.A certain of verification devices were sampled after verification,and the coverage rate of medical equipment metrological verification in the hospital was estimated based on the corresponding value of the sampled devices.Results Statistical analysis on the verification devices in 3 a showed the coverage rate of verification was enhanced from 45.5％ to 97.5％.Conclusion PDCA cycle contributes to increasing the coverage rate of medical equipment metrological verification.
Résumé
Objective To analyze the metrological verification parameters and methods for dual-energy X-ray absorptiometry (DEXA) to facilitate magnitude traceability.Methods DEXA's principle was discussed from the aspects of dual-energy X-ray absorption method and hardware structure.The method combining corresponding theory and specifications was used to describe the measurement accuracy and repeatability as well as the verification method and data processing for radiation protection performance parameters.Theoretical analysis was executed on corresponding parameters.Results Theoretical analysis was carried out on the metrological verification parameters of DEXA from the aspects of principle structure and measuring method.Conclusion It's of great significance for enhancing DEXA metrological verification to master the metrological verification parameters and methods.
