As a fast, accurate and effective identification method, radio frequency identification technology has been widely used in the medical and health industry. This paper explores the potential interference of radio frequency identification (RFID) equipment by analyzing the electromagnetic compatibility standards and related requirements of medical equipment in the medical environment, and proposes measures to reduce interference. As a fast, accurate and effective identification method, radio frequency identification (RFID) technology has been widely used in the medical and health industry. With the rapid development of hospital informationization in recent years, RFID technology has been widely used in hospital personnel tracking management, blood product management, drug management, bed management, consumables and equipment tracking management. On the one hand, it can improve the efficiency of medical staff, on the other hand, it can reduce the occurrence of medical errors and reduce the risk of treatment. However, while a new technology brings convenience, it will inevitably bring about unknown problems. There is a risk of Electromagnetic Interference (EMI) in electronic medical devices. For the application of RFID devices in the medical environment, China has not developed corresponding use standards and specifications, so some scholars question whether it will cause potential electromagnetic interference to normal medical devices like mobile phones or other radio transmitting devices. Relevant research has been carried out abroad. In 2007, Seidman et al. of the US FDA demonstrated that RFID devices can cause certain electromagnetic interference to cardiac pacemakers and implantable cardiac defibrillators. In this report, 71% of low-frequency devices and 11% of high-frequency devices generate interference waves for implantable products. In 2008, Togt et al. of the University of Amsterdam Medical Center in the Netherlands demonstrated that RFID systems can cause different levels of electromagnetic interference to medical devices. The study, conducted in a controlled environment, showed that UHF RFID interfered with 63% of medical devices. Hoelsher et al. of the German Center for Medical Technology and Ergonomics also demonstrated through experiments that RFID UHF systems can generate electromagnetic fields that exceed safety standards for medical devices. These foreign test studies have proved that existing RFID devices can cause potential electromagnetic interference to medical devices, which affects the normal operation of the device and even threatens the patient's life safety. Therefore, the electromagnetic interference problem of RFID on medical devices is particularly worthy of careful consideration.
