Description

Operating room stick instrument electronic identifier

The present invention relates to a wireless identification device for rod-type instruments in operating room, which can be easily, stably and reliably installed on the rod body of metal instruments, and has a good and stable reading effect of an external electronic reading device.

Today's medical institutions are constantly striving to improve the quality of medical care to avoid the occurrence of medical negligence; but unfortunately, medical negligence is still inevitable. Therefore, the issue of patient safety has always been one of the most important issues for the World Health Organization (WHO) and countries in Europe, America and Japan, 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, a team of surgeons, anesthesiologists, anesthesia nurses, mobile nurses and other operating room personnel is required to perform surgery. In the case of medical error, 16.9% of adverse surgical events were medical negligence. In order to reduce medical errors, negligence and improve the safety of preoperative care of patients in the operating room, the preoperative disinfection supply department will check and package the equipment; supervise the use of the equipment during the operation; post-operative equipment recovery, classification, inventory and disinfection work is very important. RFID radio frequency identification technology is used for the identification of surgical instruments, which should bring safety and efficiency to the above work, especially the identification/tracking of surgical instruments before and after use. The hospital can ensure the completeness and thoroughness of 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 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 be faced with how to incorporate a large number of existing instruments into system management; the existing sticker-type RFID electronic tags on the market are generally only attached to the instruments by stickers, which are easy to be lost during the cleaning and disinfection process. Situation; especially for stick-type instruments such as blood aspirator heads, nerve strippers, curettes, laparoscopes, etc., due to the smooth rod body, it is difficult for RFID electronic tags to be reliably attached and used on the instrument rod body.

2‧Electronic label reading signal is susceptible to interference:

Most surgical instruments are made of non-rusting metal materials, and RFID tags on the market are attached to the instruments. The transmission and reception of electromagnetic wave reading signals are susceptible to metal interference, resulting in unstable, bad or wrong signal reading.

Therefore, in order to solve the above problems, how to reliably install RFID electronic identification elements on existing instruments and have stable and effective reading effects is a technical problem that needs to be solved urgently in the use of RFID identification systems for surgical instruments today.
