The development of RFID technology is changing with each passing day. From warehouse management to banknote tracking of bank ATMs, almost every industry can find corresponding applications. In the medical field, which is closely related to people's lives, RFID gradually reflects its advanced nature in a more practical and innovative application. The application of RFID in the medical field is mainly based on tracking medical equipment, and it has already developed quite mature applications in hospital beds, wheelchairs, infusion pumps and other equipment. RFID helps medical institutions locate the location of these assets, records the use and maintenance information of assets, and prevents the theft and loss of assets. It is very important for medical institutions to efficiently and reasonably manage inventory. In addition to large asset management, RFID can also be used to set permissions for certain confidential files, track documents, and manage patient information. However, with the deeper application of RFID, the medical field has put forward more challenging requirements for it: tracking surgical instruments to avoid the loss of surgical instruments in patients and causing serious medical accidents and complications. At present, in the inventory and management of surgical instruments, laser marking or high-frequency RFID tags are frequently used. However, the effect of these methods is not ideal. In addition to the slow reading speed, these technologies do not allow multiple tags to be read at the same time, and still cannot achieve efficient and safe management. UHF RFID tags have the characteristics of long-distance reading and simultaneous group reading, which is very suitable for process management that requires real-time monitoring. The RFID tags used for medical surgical instrument tracking must meet medical standards and biocompatibility, and can withstand repeated high temperature and high pressure steam sterilization and chemical cleaning cycles. In addition, due to the special volume shape of surgical instruments, the size and installation of the label itself The method must be very special, and the tag must be able to be used in a metal environment. These conditions are indispensable for the application of surgical instrument RFID. At present, Xerafy XS series high-temperature and high-pressure steam sterilized metal tags have appeared in the industry to meet all the above requirements. The XS series of labels have 2 different types of labels, and their sizes are suitable for installation on most surgical instruments, and can be embedded in instruments to minimize the impact on use. These 2 labels have a long read and write distance It is up to 2 meters, which meets the US FDA medical device specifications, can withstand repeated high temperature and high pressure steam sterilization cycles, and is the smallest UHF metal tag in the industry. Such a small size label is also suitable for future minimally invasive surgery, such as orthopedics, spinal shell, neurosurgery, otolaryngology, etc. RFID replaces optical or electromagnetic technology to help doctors accurately locate the position of equipment and record important information. The price of RFID gradually decreases with the popularization of applications, especially in some emerging industries, such as medical and health. According to data from the research institute TechNavio, the application of RFID in the medical industry grew at a rate of 29% per year from 2010 to 2014.
