Electronic identification device for operating room instruments

The invention relates to an electronic identification device for operating room instruments that can be simply and firmly fixed on the handle of a metal instrument, and has an external wireless reading device with good and stable reading effects.

Today's medical institutions are constantly striving to improve the quality of medical care to avoid medical errors; unfortunately, medical errors are still inevitable. Therefore, the issue of patient safety has always been one of the most important issues of the World Health Organization (WHO) and European, American, and Japanese countries, and it is also an important issue for the health care service systems of countries around the world.

The operating room is indeed a high-risk, high-cost and complex, specialized, high-tech unit. Generally, when performing an operation, a team of surgeons, anesthesiologists, anesthesia nurses, mobile nurses and other operating room personnel must be formed. In the case of medical errors, 16.9% of surgical adverse events were medical negligence. In order to reduce medical errors and negligence and improve the safety of preoperative care for patients in the operating room, the preoperative disinfection and supply department checks and packs the equipment; supervises the use of equipment during the operation; recovers, sorts, counts and disinfects the equipment after the operation work is of paramount importance. The use of RFID radio frequency identification technology in the identification of surgical instruments should bring safety and efficiency to the above work, especially the identification/tracking of surgical instruments before and after use. The hospital can ensure complete and thorough disinfection, avoid the risk of nosocomial infection, or avoid Medical accidents occurred in which surgical instruments were left in the human body.

However, the use of RFID electronic identification tags on surgical instruments today still has the following problems Problem to be solved:

1. The electronic label on the device is easy to lose:

If surgical instruments are to be identified by the RFID system, they must first face how to incorporate the huge number of existing instruments into the system management; the existing sticker-type RFID electronic tags on the market are generally only attached to the instruments with adhesives, which are easy to be lost during the cleaning and disinfection process Situation; especially referring to scalpels, surgical tweezers and other instruments, due to the smooth surface and unreliable sticking and fixation of stickers, it is difficult to use RFID electronic tags on scalpels/tweezers.

2. Electronic tag reading signal is susceptible to interference:
