Study on Electromagnetic Interference Risk of Active Implantable Medical Devices in Multiple Unit Environment / 中国医疗器械杂志

Concerning on the safety risks caused by electromagnetic interference of patients implanted with high-risk active implantable medical devices in the environment of domestic MUs, this study evaluates and focuses on the requirements of electromagnetic compatibility in domestic and international standards for rail transit vehicles, the main mechanism of risks caused by EMI, the actual measurement of environmental data in MUs and the working performance of various active implantables in the compartment. The test results shows that all kinds of active implantable medical device samples works normally in the CRH2A EMU in China, and there is still a large margin between the measured radiation emission in MU and the limit required by the standards.

Mitigating EMI with healthcare electronic facilities referring to FDA recommendations / 医疗卫生装备

In view of China's medical equipment industry has not been equipped with a sound system and strict administration, it is wise to draw on FDA recommendations and seek effective ways of solving EMI problems. Further should focus on improving the performance of medical equipment so as to adapt to the different environment. In the end, the design of healthcare facilities to meet EMC standards is put forward specifically in four parts of electronic circuits, power circuits, display device, and the mechanical shell.
