This creation is about a wireless identification device for operating room instruments that can be easily and firmly fixed on a metal instrument ring, and has a good external reading device and a stable reading effect.

Today's medical institutions are constantly striving to improve the quality of medical care to avoid medical negligence; unfortunately, medical negligence is still inevitable. Therefore, the topic of patient safety has always been one of the most important topics of the World Health Organization (WHO), Europe, America, and Japan, and it is also an important topic of health care service systems in countries around the world.

The operating room is indeed a high-risk, high-cost, complex, professional, and high-tech unit. In general, a team of surgeons, anesthesiologists, anesthesiologists, mobile nurses, and other operating room personnel must be used to perform operations. In the case of medical errors, 16.9% of adverse surgical events were medical negligence. In order to reduce medical errors, negligence and improve the safety of pre-operative care for patients in the operating room, the disinfection and supply department before the operation performs the inventory and distribution of the equipment; the supervision of the use of the equipment during the operation; the recovery, classification, inventory and disinfection of the equipment after the operation The work is of utmost importance.
